Physiological sign detection device

[0001] The present application claims priority to the Chinese patent application No. 202410869608.1, filed on June 29, 2024, entitled "Physiological sign detection device", the Chinese patent application No. 202411403418.7, filed on September 30, 2024, entitled "Physiological sign detection device", the contents of which are incorporated herein by reference in their entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of medical devices, and in particular to a physiological sign detection device. BACKGROUND

[0003] Diabetes is a chronic disease that can cause many complications. The traditional method of monitoring diabetes is to use a blood glucose meter to prick the finger to take blood and measure the glucose concentration in the venous blood at a single point. Some current minimally invasive blood glucose detection products can achieve continuous monitoring for more than 7 days by implanting a biosensor into subcutaneous tissue to contact with tissue fluid. The minimally invasive blood glucose detection product applies a small sensor device (usually referred to as a patch) to the skin of the human body through an implant device, the sensor of the patch is guided into the subcutaneous tissue by a puncture needle to contact with the body fluid, and the patch transmits the analyte data obtained by the sensor to a terminal such as a mobile phone or a display instrument. The existing physiological sign detection device is mostly of the button type, which pops out the patch by pressing the button of the physiological sign detection device. However, the button type physiological sign detection device is prone to accidental touch, and when the physiological sign detection device is not aligned with the skin, the patch will be popped out by accidental touch of the button, resulting in failure of the physiological sign detection device, the sensor cannot be implanted into the subcutaneous tissue, and thus the blood glucose detection cannot be achieved, and the user experience is poor. SUMMARY

[0004] The present application provides a physiological sign detection device.

[0005] In a first aspect, an embodiment of the present application provides a physiological sign detection device. The physiological sign detection device comprises a lower shell, a base, a support, a first elastic member, a sensor assembly, an upper shell and a blocking member. The lower shell comprises a top wall and a side wall, the side wall of the lower shell is connected to the periphery of the top wall of the lower shell in a surrounding manner, and the side wall of the lower shell forms an opening on the side away from the top wall of the lower shell. The base is mounted on the inner side of the lower shell and is slidingly connected to the side wall of the lower shell, and the base comprises an abutting end which protrudes out of the lower shell through the opening. The support is mounted on the inner side of the base and is slidingly connected to the base. The first elastic member is connected between the top wall of the lower shell and the support. The sensor assembly is fixed to the support and located on the side of the support away from the top wall of the lower shell, and the sensor assembly comprises a sensor and a puncture needle. The upper shell is detachably fixed to the end of the side wall of the lower shell away from the top wall of the lower shell, and the upper shell covers the opening. When the physiological sign detection device is in an unused state, the blocking member is used to block the base from moving relative to the lower shell in the axial direction of the physiological sign detection device. When the upper shell is separated from the lower shell, the abutting end abuts against a biological body, the lower shell moves relative to the base in the direction of approaching the biological body, the first elastic member pushes the support towards the biological body, the sensor assembly abuts against the biological body, and the sensor is implanted into the biological body under the guidance of the puncture needle.

[0006] It can be understood that the lower shell, the base and the support can constitute a triggering mechanism of the physiological sign detection device. Because the triggering device of the triggering mechanism needs to move a certain stroke in the axial direction to complete triggering and push the support out. When the physiological sign detection device is in an unused state, by arranging the blocking member, the relative movement trend between the base and the lower shell in the axial direction can be limited, the base is blocked from moving relative to the lower shell in the axial direction of the physiological sign detection device, that is, the axial movement stroke of the base in the triggering direction is limited, the axial movement stroke of the device of the triggering mechanism is limited, the limited axial stroke is smaller than the triggering stroke, and the purpose of preventing false triggering is achieved. When the top of the physiological sign detection device falls downward, the blocking member limits the relative movement between the base and the lower shell in the axial direction, so that the physiological sign detection device will not be tripped and triggered when falling and vibrating.

[0007] In some possible implementation manners, the blocking member comprises a first stop structure and a second stop structure, the first stop structure is fixedly connected to the outer side of the base, the second stop structure is fixedly connected to the upper shell, the first stop structure and the second stop structure are oppositely arranged in the axial direction of the physiological sign detection device, and the second stop structure is located on the side of the first stop structure close to the top wall of the lower shell.

[0008] It can be understood that the second stop structure is located on the side of the first stop structure close to the bottom wall of the lower shell, when the physiological sign detection device falls or vibrates, the base moves relative to the lower shell in the axial direction of the physiological sign detection device, and before the support is triggered, the first stop structure abuts against the second stop structure, so that the relative movement between the base and the lower shell is stopped.

[0009] In some possible implementation manners, the first stop structure and the second stop structure are threads, and the pitch of the first stop structure and the pitch of the second stop structure are the same.

[0010] It can be understood that the thread structure is simple and has low manufacturing difficulty, and the first stop structure and the second stop structure are provided in the form of threads, which is conducive to reducing production costs and simplifying the mechanism.

[0011] In some possible implementation manners, the outer side of the side wall of the lower shell is provided with a clamping thread, and the upper shell is detachably fixed to the lower shell through the clamping thread. The pitch of the first stop structure and the pitch of the clamping thread are the same.

[0012] In this way, when the upper shell is detachably fixed to the lower shell through the thread, the first stop structure and the second stop structure can be better in contact and cooperation.

[0013] In some possible implementation manners, the lower shell further includes a first limiting block, the first limiting block is fixed to the inner side of the side wall of the lower shell and exposed to the opening, the base further includes a second limiting block, the second limiting block is fixed to the outer side of the abutting end, and the first limiting block and the second limiting block are oppositely arranged in the axial direction of the physiological sign detection device. The blocking piece is detachably connected to the base and abuts between the first limiting block and the second limiting block. When the physiological sign detection device is switched from the non-use state to the use state, the upper shell is separated from the lower shell, the blocking piece is separated from the base, and the abutting end abuts the biological body.

[0014] It can be understood that the first limiting block and the second limiting block are oppositely arranged in the axial direction of the physiological sign detection device, when the physiological sign detection device is subjected to a collision, the blocking piece can abut between the first limiting block and the second limiting block, the blocking piece can limit the relative movement trend between the base and the lower shell in the axial direction, and the base is blocked from moving relative to the lower shell in the axial direction of the physiological sign detection device, that is, the axial movement stroke of the base towards the triggering direction is limited. The blocking piece can also be provided as a separate structure piece that is detachably connected.

[0015] In some possible implementation manners, the blocking piece is a half-ring structure, and the central angle of the half-ring structure is greater than 180°.

[0016] It can be understood that the blocking piece is a half-ring structure, which facilitates a user to remove the blocking piece after removing the shell cap assembly when using the physiological sign detection device, so as to unlock and enable the triggering mechanism to work normally. In addition, the central angle of the half-ring structure is greater than 180°, and the blocking piece can be clamped to the base by means of its own structure, without the need for additionally arranging a fixed structure piece.

[0017] In some possible implementation manners, the surface of the blocking piece away from the base is provided with an anti-skid pattern. In this way, it is convenient for a user to hold the blocking piece.

[0018] In some possible implementation manners, the abutting end is provided with a limiting slot, and an opening of the limiting slot is located on the outer side surface of the abutting end.

[0019] The upper shell comprises a top wall and a side wall, the side wall of the upper shell is connected to the periphery of the top wall of the upper shell in a surrounding manner, and the blocking piece is fixedly connected to the inner side of the side wall of the upper shell. When the upper shell is mounted on the lower shell, the blocking piece is partially located in the limiting slot.

[0020] It can be understood that, when the upper shell is mounted on the lower shell, the blocking piece is partially located in the limiting slot. In a direction parallel to the axial direction (Z-axis) of the physiological sign detection device, the blocking piece and the base are oppositely arranged, and when the physiological sign detection device is subjected to an impact, the blocking piece can limit the relative movement tendency between the base and the upper shell in the axial direction. In addition, the lower shell is fixed to the upper shell. Therefore, the blocking piece can limit the relative movement tendency between the base and the lower shell in the axial direction, and limit the axial movement range of the base towards the triggering direction.

[0021] In some possible implementation manners, the blocking piece is a screw, and the limiting slot is a threaded slot, and the pitch of the limiting slot is the same as the pitch of the blocking piece.

[0022] It can be understood that the blocking piece can be better matched with the limiting slot. The blocking piece can be longer in the axial direction of the upper shell. The contact area between the blocking piece and the base can be larger, and the base can be better blocked from moving relative to the lower shell in the axial direction of the physiological sign detection device.

[0023] In some possible implementation manners, the number of blocking pieces is multiple, the multiple blocking pieces are arranged at intervals, and the multiple blocking pieces are uniformly arranged in the axial direction of the physiological sign detection device.

[0024] It can be understood that, compared with the scheme in which the number of blocking pieces is one, the number of blocking pieces is set to be larger, which is beneficial to increasing the contact area between the blocking piece and the base, and the base can be better blocked from moving relative to the lower shell in the axial direction of the physiological sign detection device.

[0025] In some possible implementation manners, the base further comprises multiple seventh elastic arms, the multiple seventh elastic arms are arranged at intervals in the axial direction of the base, the end of the seventh elastic arm is provided with a hook, and the hook faces the inner side of the base.

[0026] When the support moves towards the biological body and the sensor assembly abuts against the biological body, the hook of the seventh elastic arm is clamped with the support.

[0027] It can be understood that the plurality of seventh elastic arms cooperate to limit the support in the horizontal direction (the horizontal direction is perpendicular to the axial direction of the physiological sign detection device), prevent the support from shaking after interacting with the skin of the organism, keep the relative position of the support and the skin fixed, reduce the shaking of the support relative to the skin, and reduce the wound damage.

[0028] In some possible implementations, the support further includes a fixing table, the fixing table is protruded from the outer side surface of the support, the hook of the seventh elastic arm is spaced apart from the fixing table when the physiological sign detection device is in the non-use state, and the hook of the seventh elastic arm is clamped to the fixing table when the support moves towards the organism and the sensor assembly abuts against the organism.

[0029] It can be understood that the seventh elastic arm and the fixing table constitute a locking mechanism for preventing the push mechanism from returning, which can effectively reduce the risk of sliding of the support, reduce the shock amount after the sensor is implanted, and reduce the wound damage caused by implantation.

[0030] In some possible implementations, the hook of the seventh elastic arm faces away from the abutting end, and the hook of the seventh elastic arm is clamped to the side of the fixing table close to the abutting end when the sensor assembly abuts against the organism. Alternatively, the hook of the seventh elastic arm faces towards the abutting end, and the hook of the seventh elastic arm is clamped to the side of the fixing table away from the abutting end when the sensor assembly abuts against the organism.

[0031] It can be understood that the orientation of the hook of the seventh elastic arm can be changed, and the connecting surface of the hook of the seventh elastic arm and the fixing table also changes correspondingly when the orientation of the hook of the seventh elastic arm changes.

[0032] In some possible implementations, the base further includes a plurality of elastic locking buckles, the elastic locking buckles are spaced apart in the axial direction around the base, one end of the elastic locking buckle away from the top wall of the lower shell and the abutting end are spaced apart, and the elastic locking buckle protrudes from the inner side of the base.

[0033] When the support moves towards the organism and the sensor assembly abuts against the organism, the elastic locking buckle abuts against the side of the support close to the top wall of the lower shell.

[0034] It can be understood that the plurality of elastic locking buckles can be used to limit the support in the axial direction to avoid sliding of the support in the axial direction. The plurality of elastic locking buckles abut against the support in the axial direction around the support, limit the support in the horizontal direction, prevent the support from shaking after interacting with the skin, keep the relative position of the support and the skin fixed, reduce the shaking of the support relative to the skin, and reduce the wound damage.

[0035] In some possible implementations, the support further includes a flange, the flange is protruded from the outer side surface of the support. When the support moves towards the organism and the sensor assembly abuts against the organism, the elastic locking buckle abuts against the side of the flange close to the top wall of the lower shell.

[0036] It can be understood that when the bracket is unlocked, under the action of the first elastic member, the flange of the bracket can expand the elastic locking buckle during the downward movement, and when the bracket pushes the sensor assembly to the position, the elastic locking buckle rebounds and abuts against one side of the flange of the bracket close to the top wall of the lower shell, so as to limit the bracket in the axial direction.

[0037] In some possible implementation manners, the sensor includes a switching magnet, and the switching magnet is used to control the on-off of the sensor.

[0038] The physiological sign detection device further includes a first magnet, the first magnet is fixedly connected to the bracket, and is located between the bracket and the sensor assembly. In the axial direction of the physiological sign detection device, the first magnet and the switching magnet are oppositely arranged. When the physiological sign detection device is in an unused state, the first magnet is used to make the sensor off.

[0039] It can be understood that by arranging the switching magnet and the first magnet, when the physiological sign detection device is in the unused state, the first magnet can act on the switching magnet to make the sensor off. By physically turning on and off the power, the storage power consumption of the physiological sign detection device is reduced, and the product endurance is improved. When the physiological sign detection device is in a used state, after the upper shell is opened, before the sensor assembly abuts against the biological body, the sensor can be powered on or off. Specifically, the sensor can be set according to requirements.

[0040] In some possible implementation manners, the physiological sign detection device further includes a second magnet, the second magnet is fixedly connected to the upper shell, and in the axial direction of the physiological sign detection device, the second magnet and the switching magnet are oppositely arranged.

[0041] When the physiological sign detection device is in the unused state, the second magnet is used to make the sensor off.

[0042] It can be understood that compared with the scheme of arranging only the first magnet, the first magnet and the second magnet are arranged at the same time, the switching magnet is acted on to make the sensor off, and the acting force of the first magnet and the second magnet on the switching magnet can be greater, which is beneficial to ensure that the sensor is off when the physiological sign detection device is in the unused state.

[0043] In some possible implementation manners, the sensor assembly can further include a first pole piece and a second pole piece, the first pole piece and the second pole piece are electrically connected to the positive electrode and the negative electrode respectively, and in the axial direction of the physiological sign detection device, the switching magnet is located between the first pole piece and the second pole piece. The switching magnet is fixedly connected to the first pole piece, the first pole piece can be deformed, the switching magnet and the second pole piece are spaced apart when the physiological sign detection device is in the unused state, the sensor is off, and the switching magnet and the second pole piece are in contact and electrically connected when the physiological sign detection device is in the used state, the sensor is powered on.

[0044] It can be understood that, compared with the switch magnet being located on the same side of the first pole piece and the second pole piece, the switch magnet needs to contact the first pole piece and the second pole piece at the same time to realize the power-on of the sensor. In the embodiment, the switch magnet only needs to contact the unconnected pole piece to realize the power-on of the sensor, thereby reducing the risk that the sensor cannot be normally powered on.

[0045] In some possible implementation manners, the first pole piece comprises an ultrathin steel sheet. It can be understood that the ultrathin steel sheet can conduct electricity and has better strength.

[0046] In some possible implementation manners, the sensor assembly further comprises a needle seat, the puncture needle is fixedly connected to the needle seat, and the puncture end of the puncture needle protrudes relative to the needle seat. The physiological sign detection device further comprises a needle pulling seat, the needle pulling seat is clamped to the support, the lower shell or the base, and the needle pulling seat clamps the needle seat. When the support moves towards the biological body, the support pushes the needle seat towards the biological body through the needle pulling seat, and the puncture end of the puncture needle penetrates into the biological body.

[0047] It can be understood that the needle pulling seat clamps the needle seat, so that the needle seat can move synchronously with the needle pulling seat. When the support moves along the implantation direction, the support can push the sensor assembly to also move along the implantation direction, so that the adhesive part of the sensor assembly can be pasted to the biological body. Moreover, the support pushes the needle seat towards the biological body through the needle pulling seat, so that the puncture needle can penetrate into the biological body. When the needle pulling seat moves along the reverse direction of the implantation direction, the needle pulling seat drives the puncture needle to move along the reverse direction of the implantation direction through the needle seat, so that the puncture needle can be separated from the biological body.

[0048] In some possible implementation manners, the physiological sign detection device further comprises a second elastic member, the second elastic member is located between the support and the needle pulling seat, or the second elastic member is located on the side of the needle pulling seat close to the top wall of the lower shell. When the sensor penetrates into the implanted biological body, the second elastic member is used to move the needle pulling seat away from the biological body, the needle pulling seat and the puncture needle move away from the biological body, and the puncture needle is separated from the biological body.

[0049] In some possible implementation manners, the second elastic member abuts between the support and the needle pulling seat, and the second elastic member is in a compressed state.

[0050] It can be understood that the second elastic member can be a compression spring or the like. The second elastic member pushes the needle pulling seat away from the support, that is, away from the biological body, from the side of the needle pulling seat close to the support.

[0051] In some possible implementation manners, the second elastic member is located on the side of the needle pulling seat close to the top wall of the lower shell, one end of the second elastic member is connected to the needle pulling seat, and the other end is connected to the lower shell. The second elastic member is in a stretched state.

[0052] It can be understood that the second elastic member can be a tension spring, a clockwork, or the like. The second elastic member pulls the needle holder away from the bracket from the side of the needle holder away from the bracket, that is, away from the living body.

[0053] In some possible implementations, the second elastic member is located between the bracket and the needle holder, and the second elastic member is a spring. Alternatively, the second elastic member is located at the side of the needle holder close to the top wall of the lower shell, and the second elastic member is a needle holder clockwork or a tension spring.

[0054] In some possible implementations, the bracket includes a side plate and a bottom plate, the side plate of the bracket is in a cylindrical shape, and the side plate is fixedly connected to the side of the bottom plate close to the top wall of the lower shell, the needle holder is located on the inner side of the side plate of the bracket, and the sensor assembly is located on the side of the bottom plate of the bracket away from the top wall of the lower shell. The base includes a pre-needle pressing rib and a needle pressing rib, and the pre-needle pressing rib and the needle pressing rib are both protruded on the inner side of the base. The side plate of the bracket is provided with a clamping hole penetrating through the side plate of the bracket, the wall surface of the clamping hole includes a first step surface and a second step surface, the distance between the first step surface and the base is smaller than the distance between the second step surface and the base, and the distance between the first step surface and the bottom plate of the bracket is smaller than the distance between the second step surface and the bottom plate of the bracket. The needle holder includes an elastic buckle, when the physiological sign detection device is in an unused state, one end of the elastic buckle abuts against the first step surface, the middle part of the elastic buckle protrudes out of the side plate of the bracket via the clamping hole, in the axial direction of the physiological sign detection device, the middle part of the elastic buckle is oppositely arranged with the pre-needle pressing rib and the needle pressing rib. The first elastic member pushes the bracket towards the living body, during the process that the sensor assembly abuts against the living body, when the bracket moves to a first position, the middle part of the elastic buckle abuts against the pre-needle pressing rib, one end of the elastic buckle abuts against the second step surface, when the bracket moves to a second position, the middle part of the elastic buckle abuts against the needle pressing rib, the elastic buckle is entirely located on the inner side of the side plate of the bracket, when the bracket moves to a third position, the sensor assembly abuts against the living body, when the sensor is implanted into the living body, the second elastic member is used to move the needle holder and the puncture needle away from the living body, the puncture needle is separated from the living body.

[0055] It can be understood that the present embodiment shows a segmented needle extraction design, the pre-needle can pull the puncture needle by a distance, so that the threaded plastic on the needle holder is retracted in advance during implantation. Avoiding the plastic part from contacting the skin and causing extrusion to the wound.

[0056] In some possible implementations, the sensor assembly further includes a sealed bottle, the sealed bottle is detachably fixedly connected to the needle holder, and the sealed bottle has a hollow cavity, part of the sensor and the puncture end of the puncture needle are located in the hollow cavity of the sealed bottle.

[0057] The sealed bottle comprises a plurality of first elastic arms protruding from the outer side of the sealed bottle, and the upper shell further comprises an unlocking ratchet wheel, which is arranged in cooperation with the plurality of first elastic arms. During the screwing of the upper shell relative to the lower shell, the first elastic arms are slidingly connected to the unlocking ratchet wheel, and during the disengagement of the upper shell from the lower shell, the first elastic arms are clamped to the unlocking ratchet wheel and push the sealed bottle away from the needle seat.

[0058] It can be understood that the sealed bottle can be used to protect the puncture needle from microbial contamination. The unlocking ratchet wheel cooperates with the first elastic arms, and when the upper shell is disengaged from the lower shell, the sealed bottle is pushed away from the needle seat, so that the puncture needle and the sensor are exposed, which helps to simplify the operation steps of the physiological sign detection device and improve the user experience.

[0059] In some possible implementations, the sealed bottle further comprises a plurality of second elastic arms protruding from the outer side of the sealed bottle, and the ratchet wheel is arranged in cooperation with the plurality of second elastic arms. The plurality of first elastic arms constitute a first elastic arm group, and the plurality of second elastic arms constitute a second elastic arm group, and the first elastic arm group and the second elastic arm group are arranged staggered in the axial direction of the physiological sign detection device.

[0060] It can be understood that the rotation angles of the elastic arms in different groups are different, and there is a rotation angle a between the two groups of elastic arms. That is, any one group of elastic arms in the two groups of elastic arms is rotated by an angle a relative to the other group of elastic arms, and the two groups of elastic arms coincide in the axial direction. For example, when the sealed bottle is installed on the unlocking ratchet wheel, the end surface of the first group of elastic arms can be engaged with the short side of the inclined teeth of the ratchet wheel, and the end surface of the second group of elastic arms is arranged in a spaced manner with the short side of the inclined teeth of the ratchet wheel. At this time, the sealed bottle needs to be rotated by an angle a1 relative to the unlocking ratchet wheel to realize the engagement of the end surface of the second group of elastic arms with the short side of the inclined teeth of the ratchet wheel. a can be equal to C x (360° / n)+a1, C is a non-zero integer. a1 can be greater than 0° and less than (360° / n). For example, a1=(360° / 2n), when n=12, a can be (C x 30°+15°), and a1 can be (360° / 24)=15°. In this way, the second group of elastic arms only needs to be rotated by 15° relative to the unlocking ratchet wheel to realize the engagement with the short side of the inclined teeth of the ratchet wheel.

[0061] In some possible implementation manners, the sensor assembly further includes a needle seat, the puncture needle is fixedly connected to the needle seat, and a puncture end of the puncture needle protrudes relative to the needle seat. The sensor assembly further includes a sealed bottle, the sealed bottle is detachably fixed to the needle seat, and the sealed bottle has a hollow cavity, part of the sensor and the puncture end of the puncture needle are located in the hollow cavity of the sealed bottle. The upper shell includes a bottom wall, a side wall, a clamping arm and a clamping boss, the side wall of the upper shell is connected to a circumferential edge of the bottom wall of the upper shell in a surrounding manner, one end of the side wall of the upper shell away from the bottom wall of the upper shell detachably fixes the lower shell, and the clamping boss is fixedly connected to one side of the bottom wall of the upper shell facing the top wall of the lower shell, the clamping boss is provided with a clamping groove, an opening of the clamping groove faces the top wall of the lower shell, and when the physiological sign detection device is in an unused state, one end of the sealed bottle away from the needle seat abuts in the clamping groove;

[0062] The bottom wall of the upper shell is provided with a mounting hole penetrating through the bottom wall, one end of the clamping arm is detachably connected to the bottom wall of the upper shell, the other end of the clamping arm extends into one side of the bottom wall of the upper shell facing the top wall of the lower shell through the mounting hole, and the other end of the clamping arm is detachably connected to the sealed bottle. During the process that the upper shell is separated from the lower shell, the clamping arm clamps the sealed bottle and pushes the sealed bottle to separate from the needle seat.

[0063] It can be understood that, in the embodiment, the clamping arm is taken as an independent detachable structural member, and the sealed bottle is assembled first, so that the sealed bottle can be prevented from being knocked and deviated when the clamping arm is assembled, and the subsequent separation of the sealed bottle is facilitated.

[0064] In some possible implementation manners, the sealed bottle has a limiting groove, and an opening of the limiting groove is located on a side wall of the sealed bottle. One end of the clamping arm away from the top plate of the upper shell is provided with a clamping hook, the clamping hook of the clamping arm faces the sealing member, the clamping hook of the clamping arm is at least partially located in the limiting groove, and a groove wall of the limiting groove includes a first limiting surface and a second limiting surface, the first limiting surface and the second limiting surface are arranged at intervals along a circumferential direction of the sealed bottle, and the clamping hook of the clamping arm is located between the first limiting surface and the second limiting surface.

[0065] It can be understood that, in the embodiment, along the circumferential direction of the sealed bottle, the limiting groove of the side surface of the sealed bottle has two limiting surfaces (the first limiting surface and the second limiting surface), during the process that the upper shell drives the sealed bottle to rotate during the process that the upper shell is separated from the lower shell, the contact surface between the clamping arm and the sealed bottle is relatively large, the clamping hook of the clamping arm has limiting surfaces on both sides, and the sealed bottle is not easy to separate from the upper shell, thereby reducing the risk that the sealed bottle falls and damages the puncture needle and the adhesive member during the separation of the sealed bottle.

[0066] In some possible implementation manners, the groove wall of the limiting groove further includes a third limiting surface, the third limiting surface is connected to the first limiting surface and the second limiting surface, and the third limiting surface and the clamping hook of the clamping arm are arranged opposite to each other in a direction parallel to an axial direction of the sealed bottle.

[0067] It can be understood that when the physiological sign detection device switches from the non-use state to the use state, the clamping arm can clamp the sealed bottle through the third limiting surface and push the sealed bottle away from the needle seat during the process of the upper shell being separated from the lower shell.

[0068] In some possible implementation manners, the limiting grooves are a plurality of limiting grooves, the plurality of limiting grooves are arranged at intervals along the circumference of the sealed bottle, and the clamping arms are a plurality of clamping arms, the plurality of clamping arms and the plurality of limiting grooves are arranged in one-to-one correspondence.

[0069] In this way, a plurality of clamping arms can be arranged to clamp the sealed bottle from all around, so as to reduce the risk of the sealed bottle falling when the sealed bottle is taken off.

[0070] In some possible implementation manners, the outer diameter of the clamping protrusion is greater than the outer diameter of the sealed bottle. In this way, the clamping arm is not easy to knock against the sealed bottle during installation, so as to reduce the risk of the sealed bottle being damaged and avoid the sealed bottle being unable to be taken off together with the upper shell when the upper shell is separated from the lower shell.

[0071] In a second aspect, the embodiments of the present application provide a physiological sign detection device. The physiological sign detection device comprises a shell, a support, a first elastic member, a sensor assembly, a key module, and a front sealing cover. The shell comprises a middle plate, an upper sidewall, and a lower sidewall. The middle plate comprises a first face and a second face arranged oppositely. The upper sidewall is fixedly connected to the first face. The lower sidewall is fixedly connected to the second face. The upper sidewall and the lower sidewall are both circumferentially connected to the periphery of the middle plate. The upper sidewall and the middle plate enclose a first space. The lower sidewall and the middle plate enclose a second space. The middle plate has a first clamping hole penetrating through the middle plate and connecting the first space and the second space. The support comprises a main body, two first clamping arms, and at least one second clamping arm. The main body is located on the inner side of the lower sidewall and is slidably connected to the lower sidewall. The first clamping arm and the second clamping arm are both fixedly connected to one end of the main body close to the middle plate. The two first clamping arms and the second clamping arm are circumferentially connected to the periphery of the main body at intervals. The first clamping arm has a first clamping hook at the end away from the main body. The second clamping arm has a second clamping hook at the end away from the main body. The first clamping arm and the second clamping arm are both partially located in the first clamping hole. The first clamping hook is located in the first space and clamped to the middle plate. The second clamping hook is located in the first space and clamped to the middle plate. The first elastic member is abutted between the middle plate and the support. The sensor assembly is fixed to the main body and located on the side of the main body away from the middle plate of the shell. The sensor assembly is located in the second space. The sensor assembly comprises a sensor and a puncture needle. The key module comprises two keys, two first push blocks, and at least one second push block. The first push block and the second push block are both located in the first space. The upper sidewall has two mounting holes penetrating through the upper sidewall and connecting the first space and the outside. The keys are mounted in the mounting holes. One end of the keys is exposed to the outside, and the other end is abutted to the first push block. The two ends of the second push block are respectively abutted to the two first push blocks. The first clamping arm and the first push block are oppositely arranged in a first direction. The second clamping arm and the second push block are oppositely arranged in a second direction. The first direction and the second direction are arranged at an angle. The front sealing cover is detachably fixed to the end of the lower sidewall away from the middle plate. When the front sealing cover is separated from the lower sidewall, the end of the lower sidewall away from the middle plate abuts against a living body. The two keys are simultaneously subjected to pressure towards the central axis of the physiological sign detection device, pushing the two first push blocks towards the central axis of the physiological sign detection device. The two first push blocks push the second push block towards the central axis of the physiological sign detection device. The first clamping hook and the second clamping hook enter the second space from the first space. The first elastic member pushes the support towards the living body. The sensor assembly abuts against the living body. The sensor is implanted into the living body under the guidance of the puncture needle.

[0072] It can be understood that the key module of the embodiment includes two keys. When the physiological sign detection device falls or is accidentally touched, one side key is pressed and only one first push block moves, and two second push blocks cannot move at the same time, so at most one clamping arm is released, and the other three clamping arms can still be clamped with the shell to prevent falling or accidental touch. In this way, the physiological sign detection device in the embodiment only presses one key, or the key touches the ground when falling, or the key is not accidentally triggered when vibrating.

[0073] In some possible implementation manners, two ends of the second push block are located on the sides of the two first push blocks close to the central axis of the physiological sign detection device. The first clamping arm part is located on the side of the first push block close to the central axis of the physiological sign detection device. The second clamping arm part is located on the side of the second push block close to the central axis of the physiological sign detection device.

[0074] In some possible implementation manners, the shell further includes a boss fixedly connected to the middle part of the middle plate and located in the first space, and the two first push blocks and the at least one second push block are located between the boss and the upper side wall. The key module further includes an elastic piece located between the boss and the second push block.

[0075] It can be understood that the elastic piece can be used for resetting the first push block or the second push block after the support is released. When the user presses two keys at the same time, the first push block presses the second push block to move close to the middle, and the elastic piece is pressed. When the user removes the pressure on the first key and the second key, the elastic piece can push the second push block back to the original initial position. At the same time, the second push block abuts against the first push block, and the second push block is reset by the force of the elastic piece, which can also push the first push block back to the initial position. The first push block moves outward, further pushing the two keys back to the positions before being pressed.

[0076] In some possible implementation manners, the number of elastic pieces is two, the second push block includes a first abutting end and a second abutting end, the first abutting end is located between one first push block and one elastic piece, and the second abutting end is located between another first push block and another elastic piece.

[0077] It can be understood that the number of elastic pieces can be twice the number of second push blocks, and the two abutting ends (the first abutting end and the second abutting end) of the second push block abutting against the first push block correspond to one elastic piece, so that the force acting on the second push block is more balanced.

[0078] In some possible implementation manners, the number of second push blocks is two, and the two second push blocks are arranged in the second direction and located on the two sides of the central axis of the physiological sign detection device. In this way, the force acting on the key module is more symmetrical.

[0079] In some possible implementation manners, the sensor assembly further comprises a needle seat, the puncture needle is fixedly connected to the needle seat, and a puncture end of the puncture needle protrudes relative to the needle seat. The physiological sign detection device further comprises a needle extraction seat, the needle extraction seat is clamped to the shell, and the needle extraction seat is clamped to the needle seat. When the support moves towards the living body, the support pushes the needle seat towards the living body through the needle extraction seat, and the puncture end of the puncture needle penetrates into the living body.

[0080] It can be understood that the needle extraction seat clamps the needle seat, so that the needle seat can move synchronously with the needle extraction seat. When the support moves in the implantation direction, the support can push the sensor assembly to also move in the implantation direction, so that the adhesive part of the sensor assembly can be attached to the living body. In addition, the support pushes the needle seat towards the living body through the needle extraction seat, so that the puncture needle can penetrate into the living body. When the needle extraction seat moves in the direction opposite to the implantation direction, the needle extraction seat drives the puncture needle to move in the direction opposite to the implantation direction through the needle seat, so that the puncture needle can be separated from the living body.

[0081] In some possible implementation manners, the physiological sign detection device further comprises a second elastic member, the second elastic member is located between the support and the needle extraction seat, or the second elastic member is located on one side of the middle plate of the needle extraction seat close to the shell. When the sensor penetrates into the living body, the second elastic member is used to move the needle extraction seat away from the living body, the needle extraction seat and the puncture needle move to the side away from the living body, and the puncture needle is separated from the living body.

[0082] It can be understood that the second elastic member can be a compression spring or the like. The second elastic member pushes the needle extraction seat away from the support, that is, away from the living body, from the side of the needle extraction seat close to the support. The second elastic member can also be a tension spring, a clockwork or the like. The second elastic member pulls the needle extraction seat away from the support, that is, away from the living body, from the side of the needle extraction seat away from the support.

[0083] In some possible implementation manners, the physiological sign detection device further comprises an inclined tooth buckle, the inclined tooth buckle comprises a limiting rib and a rotating part, the rotating part is fixedly connected to the support, and the limiting rib is fixedly connected to the rotating part.

The shell further comprises the limiting rib, when the physiological sign detection device is in an unused state, the limiting rib of the inclined tooth buckle abuts against the limiting rib of the shell in the circumferential direction of the rotating part. When the support moves towards the living body, the limiting rib of the inclined tooth buckle is separated from the limiting rib of the shell, and the second elastic member is used to move the needle extraction seat away from the living body, the needle extraction seat and the puncture needle move to the side away from the living body, and the puncture needle is separated from the living body.

[0084] It can be understood that the bracket is subjected to the force of the first elastic member, the bracket moves towards the direction close to the organism, and the sensor assembly moves downwards. When the adhesive member of the sensor assembly is substantially flush with the end face of the abutting end of the shell (the trigger position of the needle extraction action), the first limiting rib and the second limiting rib are released from the constraint, the first limiting rib is separated from the second limiting rib, the bevel tooth buckle can be driven to rotate by the bevel tooth of the needle seat exerting force, the needle seat is released from the constraint locking, and the needle seat can move upwards with the guide needle under the abutting force of the second elastic member, thereby completing the needle extraction.

[0085] In some possible implementations, the physiological sign detection device further includes a plurality of lever buckles arranged around the central axis of the physiological sign detection device. The lever buckle includes a head, a middle part, and a tail. The middle part is connected between the head and the tail. The head abuts one side of the middle plate of the needle seat close to the shell. The middle part is rotationally connected to the bracket. The tail is clamped to the shell. When the bracket moves towards the direction close to the organism, the tail is separated from the shell, the needle seat and the puncture needle move away from the side of the organism, the head is pushed away from the central axis of the physiological sign detection device, and the puncture needle is separated from the organism.

[0086] It can be understood that the bracket is subjected to the force of the first elastic member, the bracket moves towards the direction close to the organism, and the sensor assembly moves downwards. When the adhesive member of the sensor assembly is substantially flush with the end face of the abutting end of the shell (the trigger position of the needle extraction action), the first limiting rib and the second limiting rib are released from the constraint, the first limiting rib is separated from the second limiting rib, the bevel tooth buckle can be driven to rotate by the bevel tooth of the needle seat exerting force, the needle seat is released from the constraint locking, and the needle seat can move upwards with the guide needle under the abutting force of the second elastic member, thereby completing the needle extraction.

[0087] In some possible implementations, the physiological sign detection device further includes a rear sealing cover detachably fixed to the end of the upper side wall away from the middle plate. The rear sealing cover wraps the end of the upper side wall away from the middle plate and closes the first space.

[0088] It can be understood that the rear sealing cover, the front sealing cover, and the shell can constitute a shell of the physiological sign detection device, for protecting internal devices of the physiological sign detection device.

[0089] In a third aspect, the embodiments of the present application provide a physiological sign detection device.

The sensor assembly is fixed to the main body and located on the side of the main body away from the middle plate of the shell, the sensor assembly is located in the second space, and the sensor assembly comprises a sensor and a puncture needle. The rear sealing cover is detachably fixed to the end of the upper sidewall away from the middle plate, the rear sealing cover wraps the end of the upper sidewall away from the middle plate, the rear sealing cover is provided with a mounting hole penetrating through the rear sealing cover and connecting the outside and the first space. The key module comprises a key, a first return spring and a sliding block, the key is fixedly connected in the mounting hole, one end of the key is exposed in the first space, the other end of the key is exposed outside through the mounting hole, the first return spring is abutted between the key and the middle plate, the sliding block is located in the rotating space, the sliding block comprises a ring part and a clamping part, the ring part is sleeved on the boss, the clamping part is connected to the side of the ring part away from the boss, and the clamping hook of the clamping arm is clamped to the clamping part of the sliding block. The front sealing cover is detachably fixed to the end of the lower sidewall away from the middle plate, the rear sealing cover wraps the end of the lower sidewall away from the middle plate and closes the second space. When the front sealing cover is separated from the lower sidewall, the end of the lower sidewall away from the middle plate abuts against a living body, the key is subjected to a pressure towards the first space, the sliding block is pushed to rotate around the central axis of the physiological sign detection device, the clamping hook of the clamping arm is separated from the sliding block, the first elastic member pushes the support towards the living body, the sensor assembly abuts against the living body, and the sensor is implanted into the living body under the guidance of the puncture needle.

[0090] It can be understood that, compared with the traditional key scheme, the embodiments convert the force received by the key in the axial direction into the force rotating in the horizontal direction, so as to avoid that the force received by the physiological sign detection device in the axial direction collides to cause the support to be loosened during the falling process.

[0091] In some possible implementation manners, the key module further includes a push block located between the slider and the key, the push block includes a first surface and a second surface located opposite to each other, the key abuts against the first surface, and the first reset spring abuts between the second surface and the middle plate. The second surface of the push block is provided with a first inclined surface, a side surface of the slider facing the push block is provided with a second inclined surface, and the first inclined surface and the second inclined surface are matched. The key is subjected to a pressure towards the first space, and when the key moves relative to the shell towards the direction close to the living body, the key moves the push block relative to the shell towards the direction close to the living body, and the push block pushes the slider to rotate around the central axis of the physiological sign detection device through the matching of the first inclined surface and the second inclined surface.

[0092] It can be understood that the user presses the key, the key can abut against the push block, the push block abuts against the abutting inclined platform of the slider, the slider is pushed to rotate relative to the shell around the axis through the matching of the first inclined surface of the push block and the second inclined surface of the slider, and the bracket can be stationary relative to the shell in the process of rotation. The clamping portion of the slider rotates relative to the clamping arm of the bracket until the clamping arm is disengaged, the clamping arm exits the first space in the first clamping hole, the bracket is released from the restriction, and the bracket moves downward under the action of the first elastic member.

[0093] In some possible implementation manners, the push block further includes a limiting portion, the limiting portion is protruded on the second surface, the boss is provided with a limiting groove, an opening of the limiting groove is located on a side surface of the boss facing the key, and the limiting portion is used to cooperate with the limiting groove to block the movement of the push block relative to the shell around the central axis of the physiological sign detection device.

[0094] It can be understood that the limiting portion can be used to clamp the boss of the shell to limit the rotation of the push block, so that the push block can move along the axial direction. The second inclined platform is used to cooperate with the inclined surface of the inclined platform of the slider to push the slider to rotate.

[0095] In some possible implementation manners, the clamping arm is a plurality of clamping arms, the plurality of clamping arms are connected to the periphery of the main body portion in a spaced and surrounding manner, the clamping portion is a plurality of clamping portions, the plurality of clamping portions are arranged around the ring portion, and the plurality of clamping arms and the plurality of clamping portions are arranged in one-to-one correspondence.

[0096] It can be understood that compared with one clamping arm, the plurality of clamping arms must be disengaged from the clamping portion at the same time to realize the launching of the bracket, and therefore, the plurality of clamping arms are beneficial to reduce the risk of false triggering of the bracket.

[0097] In some possible implementation manners, the key module further includes a second reset spring, and the shell further includes a limiting block, the limiting block and the clamping portion are arranged in a spaced manner around the central axis of the physiological sign detection device, and the second reset spring abuts between the limiting block and the clamping portion.

[0098] When the key is pressed towards the first space, the sliding block is rotated around the center axis of the physiological sign detection device, and the clamping portion is close to the limiting block, and the second reset spring is compressed.

[0099] It can be understood that by arranging the second reset spring, the sliding block is prevented from rotating in the shell due to external impact before use, so that the bracket is not triggered by mistake.

[0100] In some possible implementations, an end surface of the key away from the middle plate is located in the mounting hole and recessed towards the first space.

[0101] It can be understood that the rear sealing cover is higher than the end surface of the key. In the falling process, the rear sealing cover is deformed first after contacting the ground, and the deformation amount of the key is much smaller than the required stroke for triggering (the distance that the key needs to move upwards to contact the limiting shaft of the bracket in the normal state), so that the physiological sign detection device in the embodiment can be prevented from being triggered by mistake in the falling process.

[0102] In some possible implementations, the sensor assembly further includes a needle seat, the puncture needle is fixedly connected to the needle seat, and the puncture end of the puncture needle protrudes relative to the needle seat. The physiological sign detection device further includes a needle pulling seat, the needle pulling seat is clamped to the shell, and the needle pulling seat is clamped to the needle seat. When the bracket moves towards the biological body, the bracket pushes the needle seat towards the biological body through the needle pulling seat, and the puncture end of the puncture needle penetrates into the biological body.

[0103] It can be understood that the needle pulling seat clamps the needle seat, so that the needle seat can move synchronously with the needle pulling seat. When the bracket moves in the implantation direction, the bracket can push the sensor assembly to also move in the implantation direction, so that the adhesive member of the sensor assembly can be attached to the biological body. In addition, the bracket pushes the needle seat towards the biological body through the needle pulling seat, so that the puncture needle can penetrate into the biological body. When the needle pulling seat moves in the direction opposite to the implantation direction, the needle pulling seat drives the puncture needle to move in the direction opposite to the implantation direction through the needle seat, so that the puncture needle is separated from the biological body.

[0104] In some possible implementations, the physiological sign detection device further includes a second elastic member, the second elastic member is located between the bracket and the needle pulling seat, or the second elastic member is located on the side of the needle pulling seat close to the middle plate of the shell. When the sensor penetrates into the implanted biological body, the second elastic member is used to move the needle pulling seat away from the biological body, the needle pulling seat and the puncture needle move to the side away from the biological body, and the puncture needle is separated from the biological body.

[0105] It can be understood that the second elastic member can be a compression spring or the like. The second elastic member pushes the needle pulling seat away from the bracket, that is, away from the biological body, from the side of the needle pulling seat close to the bracket. The second elastic member can also be a tension spring, a clockwork or the like. The second elastic member pulls the needle pulling seat away from the bracket, that is, away from the biological body, from the side of the needle pulling seat away from the bracket.

[0106] In some possible implementation manners, the physiological sign detection device further comprises an inclined tooth buckle, the inclined tooth buckle comprises a limiting rib and a rotating part, the rotating part is fixedly connected to the support, and the limiting rib is fixedly connected to the rotating part. The rotating part is in a cylindrical shape, the inner surface of the rotating part is provided with inclined teeth, the outer side surface of the needle puller base is provided with inclined teeth, the inclined teeth of the rotating part and the inclined teeth of the needle puller base are meshed, and the needle puller base is rotationally connected to the inner side of the rotating part. The shell further comprises a limiting rib, when the physiological sign detection device is in an unused state, the limiting rib of the inclined tooth buckle abuts against the limiting rib of the shell in the circumferential direction of the rotating part. When the support moves towards the biological body, the limiting rib of the inclined tooth buckle is separated from the limiting rib of the shell, the second elastic member is used to move the needle puller base away from the biological body, the needle puller base and the puncture needle move to the side away from the biological body, and the puncture needle is separated from the biological body.

[0107] It can be understood that the support is subjected to the force of the first elastic member, the support moves towards the biological body, and the sensor assembly moves downwards. When the adhesive member of the sensor assembly is substantially flush with the abutting end surface of the shell (a trigger position of the needle pulling action), the first limiting rib and the second limiting rib are released from the constraint, the first limiting rib is separated from the second limiting rib, the inclined tooth buckle can be driven to rotate by the inclined teeth of the needle puller base, the needle puller base is released from the constraint locking, and the needle puller base can move upwards with the guide needle under the abutting force of the second elastic member, thereby completing the needle pulling.

[0108] In some possible implementation manners, the physiological sign detection device further comprises a plurality of lever buckles, the plurality of lever buckles are arranged around the central axis of the physiological sign detection device, the lever buckle comprises a head part, a middle part and a tail part, the middle part is connected between the head part and the tail part, the head part abuts against one side of the middle plate of the needle puller base close to the shell, the middle part rotationally connects the support, and the tail part is clamped to the shell. When the support moves towards the biological body, the tail part is separated from the shell, the needle puller base and the puncture needle move to the side away from the biological body, the head part is pushed away from the central axis of the physiological sign detection device, and the puncture needle is separated from the biological body.

[0109] It can be understood that the support is subjected to the force of the first elastic member, the support moves towards the biological body, and the sensor assembly moves downwards. When the adhesive member of the sensor assembly is substantially flush with the abutting end surface of the shell (a trigger position of the needle pulling action), the first limiting rib and the second limiting rib are released from the constraint, the first limiting rib is separated from the second limiting rib, the inclined tooth buckle can be driven to rotate by the inclined teeth of the needle puller base, the needle puller base is released from the constraint locking, and the needle puller base can move upwards with the guide needle under the abutting force of the second elastic member, thereby completing the needle pulling.

[0110] In a fourth aspect, the embodiments of the present application provide a physiological sign detection device. The physiological sign detection device comprises a lower shell, a base, a support, a first elastic member, a sensor assembly, an upper shell and a shielding mechanism. The lower shell comprises a top wall and a side wall, the side wall of the lower shell is connected to the periphery of the top wall of the lower shell in a surrounding manner, and the side wall of the lower shell forms an opening on the side away from the top wall of the lower shell. The base is installed on the inner side of the lower shell and is slidingly connected to the side wall of the lower shell. The support is installed on the inner side of the base and is slidingly connected to the base. The first elastic member is connected between the top wall of the shell and the support. The sensor assembly is fixed to the support and located on the side of the support away from the top wall of the lower shell, and the sensor assembly comprises a sensor and a puncture needle. The upper shell is detachably fixed to the end of the side wall of the lower shell away from the top wall of the shell, and the upper shell covers the opening. The shielding mechanism is used to shield the puncture needle, the shielding mechanism is fixed to the side of the base away from the top wall of the lower shell, and part of the shielding mechanism protrudes out of the lower shell through the opening. When the upper shell is separated from the lower shell, the shielding mechanism switches from the closed state to the open state when the lower shell moves towards the biological body relative to the base, the puncture needle is exposed, the first elastic member pushes the support towards the biological body, the sensor assembly abuts against the biological body, and the sensor is implanted into the biological body under the guidance of the puncture needle.

[0111] It can be understood that when the upper shell is separated from the lower shell, the shielding mechanism switches from the open state to the closed state, the shielding mechanism shields the puncture needle, and this is conducive to eliminating the fear of the puncture needle of the user during use of the physiological sign detection device.

[0112] In some possible implementation manners, when the physiological sign detection device is in an unused state, the upper shell is installed on the lower shell, and the shielding mechanism is in the open state.

[0113] When the upper shell is separated from the lower shell, the shielding mechanism switches from the open state to the closed state, and the shielding mechanism shields the puncture needle. In this way, it is conducive to eliminating the fear of the puncture needle of the user during use of the physiological sign detection device.

[0114] In some possible implementation manners, the shielding mechanism comprises a plurality of hinges, and when the shielding mechanism is in the closed state, the plurality of hinges are located on the side of the puncture needle away from the top wall of the lower shell to shield the puncture needle.

[0115] In some possible implementation manners, when the shielding mechanism is in the open state, the included angle between the plane where the hinge is located and the axial direction of the physiological sign detection device is less than or equal to 10°.

[0116] It can be understood that the hinge does not limit the axial direction of the physiological sign detection device to be parallel to the hinge, and the hinge can also be set to a larger angle, so that the hinge can be opened larger and the interference with the support is reduced.

[0117] In some possible implementation manners, the shielding mechanism further includes fixing columns, hinge shafts and torsional springs, the number of the fixing columns, the number of the hinge shafts, the number of the torsional springs and the number of the hinges are equal, the fixing columns are fixedly connected to one end of the base away from the top wall of the lower shell, the fixing columns are circumferentially connected to the periphery of the base, the hinge shafts are connected to one end of the fixing columns away from the base, the torsional springs are sleeved on the hinge shafts, the hinges are rotationally connected to the fixing columns, and the torsional springs abut against one side of the hinges close to the base.

[0118] It can be understood that when the shielding mechanism is switched from the open state to the closed state, the torsional springs can be used to provide the rotation force of the hinges; and in the closed state, the torsional springs can be used to support the hinges to shield the puncture needle.

[0119] In some possible implementation manners, the hinge includes a rotating part, a limiting part and a shielding part, the rotating part is connected between the limiting part and the shielding part, the shielding part is in a plate shape, the rotating part is rotationally connected to the fixing column, the fixing columns enclose a third space, the shielding part is located in the third space, and the limiting part is located outside the third space. The lower shell has an abutting part, the abutting part is protruded from the inner side of the side wall of the lower shell, the limiting part and the abutting part of the shell are oppositely arranged in a direction parallel to the axis of the physiological sign detection device, and the limiting part is located on one side of the abutting part away from the top wall of the lower shell. During movement of the lower shell relative to the base towards the biological body, the abutting part pushes the limiting part, one end of the limiting part away from the shielding part moves towards the biological body, the shielding part moves towards one side away from the biological body, the shielding mechanism is switched from the closed state to the open state, and the puncture needle is exposed.

[0120] In some possible implementation manners, the number of the hinges is three, and the three hinges are sequentially arranged around the central axis of the physiological sign detection device.

[0121] In some possible implementation manners, the support is provided with a sixth guide structure, the sixth guide structure is fixedly connected to one end of the support away from the top wall of the lower shell and protrudes from the outer side of the support. The physiological sign detection device further includes a guide column, the guide column is fixedly connected to one end of the base away from the top wall of the lower shell, the guide column and the fixing column are circumferentially connected to the periphery of the base, and one side of the guide column towards the third space is provided with a seventh guide structure. During pushing of the support towards the biological body by the first elastic member, the sixth guide structure and the second guide structure are slidingly connected to realize directional movement of the support.

[0122] It can be understood that during pushing of the support towards the biological body by the first elastic member, the sixth guide structure and the seventh guide structure are slidingly connected to realize directional movement of the support. Thus, the support has no activity gap with the base, so that when the support moves downwards, the amount of horizontal shaking of the support relative to the base is minimized, so as to ensure that the horizontal shaking amount of the hard needle during implantation is minimized, and the subcutaneous damage is minimized.

[0123] In some possible implementation manners, the shielding mechanism further includes a first limiting block, the first limiting block is fixedly connected to the fixed column, and is located on a side of the shielding part of the hinge away from the base. In the axial direction parallel to the physiological sign detection device, the first limiting block and the shielding part of the hinge are oppositely arranged. When the shielding mechanism is in the closed state, the first limiting block abuts against the shielding part of the hinge.

[0124] It can be understood that, by arranging the first limiting block, when the shielding mechanism is in the closed state, the first limiting block abuts against the shielding part of the hinge, so that the hinge is prevented from being abutted by the force of the torsion spring, thereby preventing the opening angle from being too large and exposing the puncture needle.

[0125] In some possible implementation manners, the shielding mechanism further includes a limiting column, a bearing plate, a second limiting block, a first push block, and a first push block return spring. The bearing plate is fixedly connected to one end of the top wall of the base away from the lower shell. The limiting column and the fixed column are both fixedly connected to a side of the bearing plate away from the base. The fixed column and the limiting column are arranged in a spaced manner. The limiting column is in a plurality. The plurality of limiting columns are arranged in a spaced manner around the central axis of the physiological sign detection device. The second limiting block is fixedly connected to the limiting column and is arranged in a spaced manner with the bearing plate. The first push block is movably connected to the limiting column. The first push block is partially located between the second limiting block and the bearing plate. The first push block return spring is abutted between the first push block and the bearing plate. The first push block includes an abutting end, which protrudes out of the lower shell through the opening. When the physiological sign detection device is in the unused state, the upper shell abuts against the first push block, and the first push block abuts against the hinge, so that the shielding mechanism is in the open state. During the process that the upper shell is separated from the lower shell, the first push block return spring pushes the first push block to move away from the top wall of the lower shell. The first push block and the hinge are arranged in a spaced manner. The hinge is pushed by the torsion spring to rotate away from the top wall of the lower shell. The shielding mechanism is switched from the open state to the closed state to shield the puncture needle. When the abutting end abuts against the living body and the lower shell moves relative to the base to move towards the living body, the first push block return spring is compressed, the first push block abuts against the hinge, the shielding mechanism is switched from the closed state to the open state, and the puncture needle is exposed.

[0126] It can be understood that, during the process that the user uses the physiological sign detection device, the upper shell is removed, the first push block return spring can apply a force to the first push block to move away from the base, the first push block moves away from the base, the two torsion springs apply a force to the two hinges to move away from the base, the hinges are closed, and the puncture needle of the sensor assembly is shielded. At this time, the user can be shielded by the hinge, and the user cannot see the puncture needle from the outside. This is favorable to eliminating the fear of the puncture needle of the user during the process that the user uses the physiological sign detection device.

[0127] In the assembly process of the physiological sign detection device, after the sensor assembly is installed to the support, the shielding structure is installed to the base, and then the upper shell is installed. The upper shell can exert a force on the push block of the shielding mechanism towards the base, the first push block moves towards the base, the first push block 5085 abuts against the hinge, so that one end of the hinge moves towards the bearing plate of the base, the torsion spring and the reset spring are compressed, and the upper shell is fixedly connected with the lower shell through threads. At this time, the hinge of the shielding mechanism remains in the open state.

[0128] In some possible implementations, the shielding mechanism further includes a bearing plate, a driving wheel, a second push block, a second push block reset spring and a driving wheel reset spring. The hinge includes a blade, a first guide column and a second guide column, the blade includes a first surface and a second surface arranged opposite to each other, the first guide column is fixedly connected to the first surface, and the second guide column is fixed to the second surface. The bearing plate is fixedly connected to one end of the top wall of the base away from the lower shell, and is provided with a first directional hole; the driving wheel is movably connected to the base, and is provided with a second directional hole; the first guide column is slidably connected to the first directional hole, and the second guide column is slidably connected to the second directional hole. The push block reset spring is arranged between the push block and the driving wheel, and the push block includes an abutting end which protrudes out of the opening relative to the lower shell. One end of the driving wheel reset spring is fixedly connected to the base, and the other end is fixedly connected to the driving wheel. When the physiological sign detection device is in an unused state, the driving wheel reset spring is in a stretched state. During the process of separating the upper shell from the lower shell, the push block reset spring pushes the push block to move away from one side of the bottom wall of the lower shell, the driving wheel reset spring is reset, the driving wheel is pulled to rotate in the opposite direction, and the plurality of hinges are rotated to make the shielding mechanism in the closed state. When the abutting end abuts against the living body, the lower shell moves relative to the base towards the direction close to the living body, the push block moves relative to the base towards the direction close to the bottom wall of the lower shell, the directional wheel is pushed to rotate, the driving wheel reset spring is stretched, and the plurality of hinges are rotated to make the shielding mechanism in the open state, and the puncture needle is exposed.

[0129] It can be understood that when the user uses it, the upper shell is removed, the plurality of hinges are rotated to make the shielding mechanism in the closed state, and when the user presses on the skin, the second push block first pushes the driving wheel to rotate by a certain angle, and then the shielding mechanism is opened, without affecting the pushing of the sensor assembly. During use, the user needs to press for a certain stroke first, then the shielding mechanism is opened, and the support is pushed out.

[0130] In some possible implementation manners, the shielding mechanism includes an alloy limiting cap and a plurality of alloy pieces, the alloy has a curved surface shape, the alloy is fixedly connected to the inner side of the base, and the alloy limiting cap is fixedly connected to the lower shell. When the physiological sign detection device is in an unused state, the end of the alloy piece away from the base is located between the base and the alloy limiting cap. After the upper shell is separated from the lower shell, the alloy limiting cap is separated from the base, and the end of the alloy away from the base is folded to shield the puncture needle. The base includes an abutting end that protrudes relative to the lower shell through the opening and abuts against the biological body, and when the lower shell moves relative to the base to the direction close to the biological body, the first elastic member pushes the support to the biological body, the support pushes away the alloy piece, so that the shielding mechanism is in an open state, and the puncture needle is exposed.

[0131] It can be understood that, compared with the previous embodiment of the shielding mechanism, in the present embodiment, the hinges of the shielding mechanism are opened while moving in the implantation process of the sensor assembly, and do not need to be pressed to open the hinges before triggering implantation, so that the pressing transmission stroke is small, and the length of the physiological sign detection device in the axial direction can be set to be smaller. In addition, the number of hinges is larger, and the hinges can better shield the puncture needle when the shielding mechanism is in a closed state, so as to ensure that the user cannot see the puncture needle, thereby eliminating the fear of needles of the user.

[0132] In some possible implementation manners, the shielding mechanism includes an alloy piece, the alloy has a curved surface shape, and the alloy is at least partially fixedly connected to the inner side of the base. When the physiological sign detection device is in an unused state, the end of the alloy piece away from the base is located between the base and the upper shell. After the upper shell is separated from the lower shell, the end of the alloy away from the base is folded to shield the puncture needle. The base includes an abutting end that protrudes relative to the lower shell through the opening and abuts against the biological body, and when the lower shell moves relative to the base to the direction close to the biological body, the first elastic member pushes the support to the biological body, the support pushes away the alloy piece, so that the shielding mechanism is in an open state, and the puncture needle is exposed.

[0133] It can be understood that, compared with the previous embodiment of the shielding mechanism, in the present embodiment, the number of hinges of the shielding mechanism is two, the occupied space is small, and in the implantation process of the sensor assembly, the hinges are opened while moving, and do not need to be pressed to open the hinges before triggering implantation, so that the pressing transmission stroke is small, and the length of the physiological sign detection device in the axial direction can be set to be smaller.

[0134] In a fifth aspect, an embodiment of the present application provides a physiological sign detection device. The physiological sign detection device includes a lower shell, a base, a support, a first elastic member, a sensor assembly, and an upper shell.

[0135] The lower shell includes a top wall and a side wall, the side wall of the lower shell is circumferentially connected to the periphery of the top wall of the lower shell, and the side wall of the lower shell away from the top wall of the lower shell forms an opening.

[0136] The base is mounted on the inner side of the lower shell and is slidingly connected to the side wall of the lower shell. The base includes a top plate, a side wall, and a resilient arm. The side wall of the base is circumferentially connected to the peripheral edge of the top plate. The resilient arm is fixedly connected to one side of the top plate away from the side wall of the base. The resilient arm abuts against the top wall of the lower shell. The base includes an abutting end which protrudes out of the opening relative to the lower shell. The support is mounted on the inner side of the base and is slidingly connected to the base. The first elastic member abuts between the base and the support. The sensor assembly is fixed to the support and is located on the side of the support away from the top wall of the lower shell. The sensor assembly includes a sensor and a puncture needle. The upper shell is detachably fixed to the end of the side wall of the lower shell away from the top wall of the shell. The upper shell covers the abutting end and closes the opening. When the abutting end abuts against the organism, the lower shell moves relative to the base towards the organism, the first elastic member pushes the support towards the organism, the sensor assembly abuts against the organism, and the sensor is implanted into the organism under the guidance of the puncture needle.

[0137] It can be understood that, when the physiological sign detection device is started, the first elastic member will not be further compressed, and the pressing force of the lower shell and the pushing force of the first elastic member are decoupled. The pressing force can be adjusted by the size of the resilient arm of the base, and the pressing force can be reduced. For example, in the previous embodiment, the pressing force = the buckle opening force + the compression force of the first elastic member. In this embodiment, the pressing force = the buckle opening force + the pressing resilient arm force.

[0138] In some possible implementations, the sensor assembly further includes a needle holder, the puncture needle is fixedly connected to the needle holder, and the puncture end of the puncture needle protrudes relative to the needle holder. The physiological sign detection device further includes a needle extraction holder, the needle extraction holder is clamped to the support, the lower shell, or the base, and the needle extraction holder clamps the needle holder. The physiological sign detection device further includes a second elastic member, the second elastic member is located between the support and the needle extraction holder, or the second elastic member is located on the side of the needle extraction holder close to the top wall of the lower shell. When the support moves towards the organism, the support pushes the needle holder towards the organism through the needle extraction holder, the puncture end of the puncture needle penetrates into the organism, and when the sensor penetrates into the organism, the second elastic member is used to move the needle extraction holder away from the organism, the needle extraction holder and the puncture needle move to the side away from the organism, the puncture needle is separated from the organism, and the first elastic member is sleeved on the outside of the second elastic member.

[0139] It can be understood that, compared with the arrangement of the first elastic member and the second elastic member in the previous embodiment which are arranged along the axial direction of the physiological sign detection device, in this embodiment, the first elastic member and the second elastic member are located on substantially the same horizontal plane and are located close to the abutting end of the physiological sign detection device. During use of the physiological sign detection device, the first elastic member and the second elastic member are more stable and less likely to shake. BRIEF DESCRIPTION OF DRAWINGS

[0403] Furthermore, “fixing” in this paper should also be understood broadly, for example, “fixing” can be direct fixing, or can be indirect fixing through intermediate medium. Wherein, “fixing” means being connected to each other and the relative positional relationship after connection is unchanged. The orientation language mentioned in the embodiments of the present application, for example, “upper”, “lower” and the like, is only the direction of the drawing, therefore, the orientation language used is to better and more clearly illustrate and understand the embodiments of the present application, and is not intended to indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore, it cannot be understood as limiting the embodiments of the present application. “Multiple” means two or more than two.

[0404] In the description of the embodiments of the present application, unless otherwise stated, “ / ” means or, for example, A / B can mean A or B; “and / or” in the text only describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can mean that A exists alone, A and B exist together, and B exists alone, in addition, in the description of the embodiments of the present application, “multiple” means two or more than two.

[0405] In the embodiments of the present application, the terms "first", "second", "third", "fourth" are only used for descriptive purpose, and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second", "third", "fourth" can explicitly or implicitly include one or more of the features.

[0406] In addition, in the embodiments of the present application, the relative position relationship mentioned, such as parallel, vertical, aligned, etc. These limits are for the current process level, not an absolute strict limit, allowing a small amount of deviation, approximately parallel, approximately vertical, approximately aligned, etc. For example, A and B are parallel, which means that A and B are parallel or approximately parallel, and the included angle between A and B can be between 0 degrees and 10 degrees.

[0407] In the embodiments of the present application, the axial arrangement around the structural member and the circumferential arrangement along the structural member are in one direction.

[0408] It can be understood that the axis of the structural member, also known as the central axis of the structural member, can also be referred to as the center axis of the structural member.

[0409] Please refer to FIG. 1 and FIG. 2, FIG. 1 is a schematic diagram of the physiological sign detection device 100 in some application scenarios provided by the present application, and FIG. 2 is a structural schematic diagram of the physiological sign detection device 100 shown in FIG. 1 in some embodiments.

[0410] As shown in FIG. 1 and FIG. 2, the physiological sign detection device 100 can include an implant device 10 and a sensor assembly 20 which is detachably mounted inside the implant device 10, and the implant device 10 is used to push the sensor assembly 20 to a target monitoring position on the living body 30 (for example, a part of the arm of the living body 30 rich in fat or the skin of the abdomen). The sensor assembly 20 can include a sensor 24244 and an adhesive 2827, and after the implant device 10 pushes the sensor assembly 20 out, the sensor assembly 20 is fixed to the living body 30 through the adhesive 2827 at the bottom of the sensor assembly 20. A part of the sensor 24244 of the sensor assembly 20 extends from the sensor assembly 20 and is implanted in the subcutaneous tissue of the skin of the living body 30 to collect and transmit blood information, so that the sensor 24244 can detect and quantify one or more physiological target substances, such as blood glucose, lactic acid, uric acid, dissolved oxygen, hydrogen peroxide, ions, etc. The sensor assembly 20 can transmit information to the terminal device 40 through short-range transmission methods such as Bluetooth or Near Field Communication (NFC). The terminal device 40 can be a display instrument, a mobile phone, an electronic watch, or other electronic devices with a display screen. In other embodiments, the terminal device can also not have a display screen. After the sensor 24244 is implanted in the living body 30, the detection of physiological target substances such as blood glucose can be set and started through an application (APP) on the terminal device 40, and the sensor assembly 20 transmits the collected physiological target substance data to the terminal device 40, and the terminal device 40 is used to observe the concentration information of the physiological target substance, so as to detect and manage the physiological and chemical indicators such as blood glucose. Among them, the sensor assembly 20 is consumable. For example, one sensor assembly 20 can be used continuously for 14 days or more. In other embodiments, the sensor assembly 20 can also be permanent.

[0411] The physiological sign detection device 100 is a one-piece device, and the sensor assembly 20 has been pre-installed inside the implant device 10 before packaging, and there is no need for the user to assemble the implant device 10 and the sensor assembly 20 during use. The user only needs to open one package and attach the physiological sign detection device 100 to the target monitoring position on the living body 30, and the implant device 10 of the physiological sign detection device 100 can push the sensor assembly 20 to the target monitoring position. The one-piece physiological sign detection device 100 helps to simplify the user's operation steps, which is convenient for the user to operate, and can also avoid the biological contamination risk caused by the user's assembly process. In addition, the physiological sign detection device 100 only needs one package, and does not need to be packaged separately for the sensor assembly 20 and the implant device 10, which is beneficial to reduce product cost and reduce packaging and waste.

[0412] FIG. 3 is a partially exploded structural schematic view of an embodiment of the physiological sign detection device 100 shown in FIG. 2.

The lower housing 1 can be generally cylindrical. The lower housing 1 has an axial direction, the side wall 11 of the lower housing 1 is arranged around the axial direction of the lower housing 1, and the top wall 12 of the lower housing 1 intersects the axial direction of the lower housing 1.

[0417] In some embodiments, the lower housing 1 can further include a first guide structure 13, which can be fixed to the inner side surface of the side wall 11 of the lower housing 1. The lower housing 1 has an inner side and an outer side, and the inner side surface of the side wall 11 of the lower housing 1 refers to the surface on the inner side of the side wall 11 of the lower housing 1, and the inner side surface hereinafter is understood in a similar manner, which will not be described herein again. The first guide structure 13 can extend along the axial direction of the lower housing 1. The number of the first guide structure 13 can be one or more, and when the number of the first guide structure 13 is more than one, the plurality of first guide structures 13 are arranged in a circumferential direction of the side wall 11 of the lower housing 1.

[0418] In some embodiments, the first guide structure 13 can include a first slider 131 and a second slider 132, which are spaced apart. The first slider 131 and the second slider 132 both extend along the axial direction of the lower shell 1. The first slider 131 and the second slider 132 are spaced apart from the top wall 12 of the lower shell 1. The number of the first slider 131 and the second slider 132 can be one or more. When the number of the first slider 131 and the second slider 132 is more than one, the plurality of first sliders 131 and the plurality of second sliders 132 are arranged in a spaced apart manner along the circumferential direction of the side wall 11 of the lower shell 1. The plurality of first sliders 131 and the plurality of second sliders 132 can be arranged alternately. For example, the number of the first slider 131 and the second slider 132 is two. The two first sliders 131 are arranged oppositely. The two second sliders 132 are arranged oppositely.

[0419] In some embodiments, the lower shell 1 can further include a first limiting boss 14 and a knob 15. The first limiting boss 14 and the knob 15 are both fixed to the top wall 12 of the lower shell 1 on the side facing the opening 101 of the lower shell 1.

[0420] In some embodiments, the first limiting boss 14 can be circular or annular. The first limiting boss 14 can enclose a first space 141 with the top wall 12.

[0421] In some embodiments, the knob 15 can be located outside the first limiting boss 14. The number of the knob 15 can be one or more. When the number of the knob 15 is more than one, the plurality of knobs 15 are arranged in a spaced apart manner along the circumferential direction of the first limiting boss 14. For example, the number of the knob 15 is two. The two knobs 15 are arranged oppositely. The knob 15 is provided with an opening slot 151. The opening slot 151 of the knob 15 can help reduce the material consumption and the weight of the lower shell 1.

[0435] FIG. 7 is a partial cross-sectional view of the physiological sign detection device 100 shown in FIG. 2, taken along the line B-B. FIG. 8 is a partial cross-sectional view of the physiological sign detection device 100 shown in FIG. 2, taken along the line C-C. FIG. 9 is a partial cross-sectional view of the physiological sign detection device 100 shown in FIG. 2, taken along the line D-D.

[0436] As shown in FIGS. 7-9, the base 5 can be mounted to the inner side of the lower housing 1 and slidingly connected to the side wall 11 of the lower housing 1. The axial direction of the base 5 can coincide with the axial direction of the lower housing 1. The end of the lower side wall 52 of the base 5 away from the upper side wall 51 is the abutting end 502, which protrudes out of the lower housing 1 through the opening 101 of the lower housing 1.

[0437] In some embodiments, the hook of the first elastic arm 54 can be clamped to the side wall 11 of the lower shell 1 to limit the movement of the lower shell 1 relative to the base 5 in a direction away from the abutting end 502. For example, the hook of the first elastic arm 54 can be clamped to the first sliding block 131, and the hook of the first elastic arm 54 is installed in the limiting space 103 between the first sliding block 131 and the top wall 12 of the lower shell 1. The first sliding block 131 abuts against the hook of the first elastic arm 54 to limit the movement of the lower shell 1 relative to the base 5 in a direction away from the lower side wall 52. It can be understood that, in the present embodiment, the hook of the first elastic arm 54 axially limits the first sliding block 131, thereby preventing the movement of the lower shell 1 relative to the base 5 in a direction away from the lower side wall 52, and preventing the lower shell 1 from being separated from the base 5.

[0438] In some embodiments, the first elastic arm 54 is circumferentially spaced apart from the upper side wall 51 of the base 5, and the hook of the first elastic arm 54 has an inclined end surface. When the base 5 is assembled with the lower shell 1, the first elastic arm 54 can elastically avoid the first sliding block 131 in a radial direction, and the inclined end surface of the hook of the first elastic arm 54 axially avoids the first sliding block 131, thereby facilitating the smooth installation of the base 5 inside the lower shell 1, reducing the clamping resistance, and also preventing damage to the base 5 and the lower shell 1 during assembly.

[0439] In other embodiments, the side wall 11 of the lower shell 1 can also have a clamping space or a clamping block, and the hook of the first elastic arm 54 can be clamped to the clamping space or the clamping block of the lower shell 1 to achieve the clamping of the first elastic arm 54 to the lower shell 1, which is not strictly limited in the present application.

[0440] In other embodiments, the positions of the hook of the first elastic arm 54 and the first sliding block 131 can also be interchanged.

[0441] In other embodiments, the first guide structure 13 is slidably connected to the second guide structure 55. The slide grooves of the first guide arm 551 and the slide grooves of the first elastic arm 54 can be used for guiding. For example, the first sliding block 131 (the first guide structure 13) is installed in the slide grooves of the first guide arm 551 and the slide grooves of the first elastic arm 54. That is, the first sliding block 131 can slide between the stepped surface 501 and the hook of the first elastic arm 54. The number of first guide arms 551 is adapted to the number of first sliding blocks 131; the second sliding block 132 is installed in the slide grooves of the second guide arm 552, and the second sliding block 132 can slide in the slide grooves of the second guide arm 552. The number of second guide arms 552 is adapted to the number of second sliding blocks 132.

[0442] It can be understood that the first guide structure 13 is slidingly connected to the second guide structure 55, and the first guide structure 13 and the second guide structure 55 cooperate to guide the lower shell 1 and the base 5 to slide relative to each other in the axial direction of the lower shell 1, and to limit the lower shell 1 and the base 5 relative to each other in the circumferential direction of the lower shell 1, so as to prevent the base 5 from rotating relative to the lower shell 1 in the circumferential direction. When the number of the first guide structure 13 and the second guide structure 55 is plural, it is helpful to balance the force between the lower shell 1 and the base 5, and to prevent the base 5 from being skewed relative to the lower shell 1. In addition, the first sliding block 131 can slide between the stepped surface 501 and the hook of the first elastic arm 54, so that the lower shell 1 can move relative to the base 5 in the axial direction, and limit the movement of the lower shell 1 relative to the base 5 in the axial direction, so as to limit the distance that the lower shell 1 can move relative to the base 5 in the implantation direction. The implantation direction is parallel to the Z-axis direction.

[0443] In other embodiments, the first guide arm 551 can also be arranged on the inner side of the lower shell 1, and the first sliding block 131 of the base 5 cooperates with the first guide arm 551 of the lower shell 1 to limit the lower shell 1 and the base 5 relative to each other in the circumferential direction, which is not strictly limited in the present application. In other embodiments, the second sliding block 132 can also be fixed to the outer side of the base 5, and the second guide arm 552 can also be fixed to the inner side of the side wall 11 of the lower shell 1, and the second sliding block 132 cooperates with the second guide arm 552 to limit the lower shell 1 and the base 5 relative to each other in the circumferential direction, which is not strictly limited in the present application. In other embodiments, the cooperation between the first guide structure 13 and the second guide structure 55 can not include the cooperation between the first sliding block 131 and the first guide arm 551, or the cooperation between the second sliding block 132 and the second guide arm 552, which is not strictly limited in the present application.

[0444] In some embodiments, the push block 15 can be located on the side of the top wall 12 of the lower shell 1 facing the base 5. When the lower shell 1 moves relative to the base 5 towards the direction of the abutting end 502, the push block 15 pushes the second elastic arm 56, and the second elastic arm 56 moves outwardly relative to the base 5.

[0445] For example, the wall surface of the guide groove of the second elastic arm 56 can further include a guide surface 261. The guide surface 261 is inclined relative to the axial direction of the base 5. One end of the push block 15 is arranged close to the guide surface 261 of the guide groove. When the push block 15 moves towards the direction of the abutting end 502, the push block 15 can move along the guide surface 261.

[0480] FIG. 18 is an assembly diagram of an embodiment of the needle holder 4 and the bracket 3 shown in FIG. 3. FIG. 19 is a partial cross-sectional view of an embodiment of the physiological sign detection device 100 shown in FIG. 2 at the section line B-B.

[0481] As shown in FIGS. 18 and 19, the needle holder 4 can be mounted to the inner side of the bracket 3. For example, the needle holder 4 can be mounted between the bottom plate 32 of the bracket 3 and the hooks of the fourth elastic arms 37. In this embodiment, the number of the fourth elastic arms 37 can be three to balance the force on the clamped needle holder 4. In this embodiment, the needle holder 4 is located between the bottom plate 32 of the bracket 3 and the hooks of the fourth elastic arms 37, so that the needle holder 4 and the bracket 3 maintain a relatively stable positional relationship, and the fourth elastic arms 37 can push the needle holder 4 to move with the bracket 3.

[0482] In some embodiments, the bracket 3 can further include a fourth limiting boss 39, which is arranged around the periphery of the mounting hole 321 and is fixed to the side of the bottom plate 32 of the bracket 3 facing the first accommodating space 301. The side plate 42 of the needle extraction seat 4 can be partially located between the fourth limiting boss 39 and the side plate 31 of the bracket 3.

[0483] In some embodiments, the guide strip 44 of the needle extraction seat 4 can be located in the guide groove 312 on the inner side of the side plate 31 of the bracket 3. The guide groove 312 of the side plate 31 of the bracket 3 can cooperate with the guide strip 44 of the needle extraction seat 4 to limit the rotation of the needle extraction seat 4. In other embodiments, the needle extraction seat 4 can be provided with a guide groove, and the inner side of the side plate 31 of the bracket 3 can be provided with a guide strip, which cooperate to limit the rotation of the needle extraction seat 4.

[0484] In some embodiments, the guide grooves of the side plate 31 of the bracket 3 and the fourth elastic arms 37 of the bracket 3 are sequentially and spacedly arranged along the circumference of the bracket 3. Any one of the guide grooves is located between two fourth elastic arms 37. In this way, the force acting on the needle extraction seat 4 is more uniform.

[0485] In some embodiments, the second elastic member 6 can be located between the bracket 3 and the needle extraction seat 4. The axial direction of the needle extraction seat 4 and the axial direction of the second elastic member 6 can both coincide with the axial direction of the bracket 3. The second elastic member 6 is in a compressed state.

[0486] For example, the needle extraction seat 4 is mounted in the first accommodating space 301 of the bracket 3, and the side plate 42 of the needle extraction seat 4 is located outside the fourth limiting boss 39. The second elastic member 6 is mounted in the third accommodating space 401 of the needle extraction seat 4. The second elastic member 6 can be, but is not limited to, a spring, elastic rubber, etc. The second elastic member 6 is located between the bottom plate 32 of the bracket 3 and the top plate 41 of the needle extraction seat 4, and is sleeved around the outer periphery of the first cantilever arm 43 and the fourth limiting boss 39. The second elastic member 6 is used to push the needle extraction seat 4 away from the bottom plate 32 of the bracket 3. The first cantilever arm 43 and the fourth limiting boss 39 limit and position the second elastic member 6, preventing the second elastic member 6 from being skewed during compression and rebound, thereby achieving the purpose of stabilizing the position of the second elastic member 6 and improving the reliability of the physiological sign detection device 100.

[0487] FIG. 20 is a partial cross-sectional structural schematic view of the physiological sign detection device 100 shown in FIG. 2 along B-B. FIG. 21 is a partial cross-sectional structural schematic view of the physiological sign detection device 100 shown in FIG. 2 along C-C. FIGS. 20 and 21 are used to show the assembly of one embodiment of the bracket 3 and the base 5.

[0488] As shown in FIG. 20 and FIG. 21, the bracket 3 is mounted inside the base 5 and is slidingly connected to the base 5. The axial direction of the bracket 3 can coincide with the axial direction of the base 5. For example, the sliding bar 392 of the bracket 3 can be slidingly connected to the sliding groove of the fifth guide structure 59 of the base 5.

[0489] In some embodiments, the third guide structure 57 of the base 5 is slidingly connected to the fourth guide structure 36 of the bracket 3. For example, the sliding block of the third guide structure 57 of the base 5 can be mounted in the sliding groove of the third elastic arm 35 and the sliding groove of the third guide arm 361 of the bracket 3, and the third sliding block can slide in the sliding groove of the third elastic arm 35 and the sliding groove of the third guide arm 361. The number of the third elastic arm 35 and the third guide arm 361 can be three, so as to balance the force of the connection between the bracket 3 and the base 5 and keep the bracket 3 and the base 5 relatively stable in the radial direction.

[0490] It can be understood that, in the present embodiment, the sliding bar 392 of the bracket 3 is slidingly connected to the sliding groove of the fifth guide structure 59 of the base 5. The third guide structure 57 of the base 5 is slidingly connected to the fourth guide structure 36 of the bracket 3, which cooperates with each other to limit the base 5 and the bracket 3 in the circumferential direction, so as to avoid the rotation of the bracket 3 relative to the base 5 in the circumferential direction. The sliding bar 392 of the bracket 3 is slidingly connected to the sliding groove of the fifth guide structure 59 of the base 5. The sliding block of the third guide structure 57 can slide in the sliding groove of the third elastic arm 35 and the sliding groove of the third guide arm 361, so that the bracket 3 can move relative to the base 5 in the axial direction.

[0491] For example, the third elastic arm 35 can also limit the movement of the bracket 3 in the axial direction. The third elastic arm 35 is arranged in the circumferential direction and is spaced apart from the side plate 31 of the bracket 3, and the other end of the third elastic arm 35 away from the bottom plate 32 of the bracket 3 is provided with an inclined end face. When the bracket 3 is assembled with the base 5, the third elastic arm 35 can elastically avoid the third sliding block in the radial direction, and the inclined end face of the third elastic arm 35 avoids the third sliding block in the axial direction, so as to facilitate the smooth installation of the bracket 3 into the inside of the base 5, reduce the clamping resistance, and also avoid damaging the bracket 3 and the base 5 during assembly.

[0492] In some embodiments, the clamping hook of the second elastic arm 56 is at least partially located in the first clamping space 303 of the bracket 3, so that the second elastic arm 56 clamps the bracket 3, and the base 5 limits the bracket 3 in the axial direction.

[0493] FIG. 22 is a partial cross-sectional structure schematic view of the physiological sign detection device 100 shown in FIG. 2 along B-B.

[0494] As shown in FIG. 22, the clamping hook of the second elastic arm 56 is at least partially located in the first clamping space 303 of the bracket 3, so that the second elastic arm 56 clamps the bracket 3, and the base 5 limits the bracket 3.

[0495] In some embodiments, the first magnet 9 can be fixedly connected to the support 3. For example, the first magnet 9 can be fixed to a side of the bottom plate 32 of the support 3 facing the lower side plate 33 of the support 3. The first magnet 9 can be used to form a magnetic activity switch.

[0496] FIG. 23 is a structural schematic diagram of an embodiment of the sensor assembly 20 shown in FIG. 3. FIG. 24 is an exploded schematic diagram of an embodiment of the sensor assembly 20 shown in FIG. 23.

[0497] As shown in FIGS. 23 and 24, the sensor assembly 20 can include a top cover 21, a needle seat 22, a puncture needle 23, a sensor 24, a battery assembly 25, an electrical connection assembly 26, a bottom cover 27, an adhesive 28, a gasket 201, and a sealing bottle 29.

[0498] In some embodiments, the top cover 21 and the bottom cover 27 can each be made of an engineering plastic such as polycarbonate, acrylonitrile-butadiene-styrene, or the like.

[0499] FIG. 25a is a structural schematic diagram of an embodiment of the sensor 24 shown in FIG. 24.

[0500] As shown in FIG. 25a, the sensor 24 can include a connecting portion 241, a fixing portion 242, and an implanting portion 243 (schematically distinguished by dashed lines in FIG. 25a), the fixing portion 242 connecting the implanting portion 243 and the connecting portion 241. The connecting portion 241 of the sensor 24 is used to electrically connect the electrical connection assembly 26 (shown in FIG. 24), and the implanting portion 243 of the sensor 24 is used to pierce the organism 30.

[0501] In some embodiments, the sensor 24 can include a substrate, an electrode layer, and a sensing layer (not shown). For example, the substrate can be made of polyethylene terephthalate (PET). The electrode layer is fixed on the surface of the substrate. The electrode layer can be formed on the surface of the substrate by an inkjet printing, screen printing, or other process to form an electrode system (e.g., two electrodes or multiple electrodes). The electrode layer can include a first portion located at the implanting portion 243, a second portion located at the fixing portion 242, and a third portion located at the connecting portion 241, and the second portion of the electrode layer connects the first portion of the electrode layer and the third portion of the electrode layer. The sensing layer is fixed on a partial area of the first portion of the electrode layer, i.e., the sensing layer is located at the implanting portion 243. The sensing layer can be formed by applying a sensing agent to the surface of the first portion of the electrode layer by inkjet printing or drop coating. The sensing agent can be a mixed solution including biological protease (e.g., glucose oxidase), an electron transfer mediator, and a cross-linking agent. After the sensor 24 is printed, the shape of the sensor 24 can be formed by femtosecond or picosecond laser cutting. It can be understood that the sensing agent of the sensing layer can be selected according to the physiological indicators to be detected.

[0502] FIG. 25b is an assembly diagram of an embodiment of the sensor 24, the needle seat 22, and the puncture needle 23 shown in FIG. 24.

[0503] As shown in FIG. 25b, the needle seat 22 can include a limiting buckle 221, a clamping portion 222, a limiting portion 223, a sealing portion 224, and a guide portion 225. The limiting buckle 221, the clamping portion 222, the limiting portion 223, the sealing portion 224, and the guide portion 225 are sequentially connected. The limiting portion 223 can be generally cylindrical, and the diameter of the clamping portion 222 is smaller than the diameter of the bottom surface of the limiting buckle 221 and the diameter of the limiting portion 223. The guide portion 225 has a recessed groove 2251 extending along the axial direction of the needle seat 22.

[0504] In some embodiments, the puncture needle 23 can be fixed to the needle seat 22 and extend along the axial direction of the needle seat 22. The puncture end 231 of the puncture needle 23 can protrude relative to the guide portion 225 of the needle seat 22. The puncture needle 23 is fixed to the recessed groove 2251 of the guide portion 225, and the shape of the recessed groove 2251 is adapted to the shape of the puncture needle 23. In some embodiments, the puncture needle 23 and the needle seat 22 can be integrally formed. In some embodiments, the two components are integrated by the integrally formed process, which means that one of the two components is connected with the other component during the process of forming the one component, and the two components are not connected together by bonding, welding, buckling, screwing, or other secondary processing.

[0505] For example, the needle hub 22 and the puncture needle 23 can be integrally formed by a mold injection process. The needle hub 22 can be made of polycarbonate, acrylonitrile butadiene styrene, or other engineering plastics. The puncture needle 23 can be made of 316 stainless steel, 304 stainless steel, medical-grade stainless steel (e.g., SUS316L), or other metal materials.

[0506] For example, the puncture needle 23 can have a substantially U-shaped cross section, and the puncture needle 23 is used to pierce and push away the tissue of the living body 30. The puncture end of the puncture needle 23 can be used to wrap the implanting part 243 of the sensor 24, and when the puncture needle 23 pierces into the living body 30, an implanting space can be formed for the implanting part 243 of the sensor 24 to pierce into the living body 30. In addition, the puncture end of the puncture needle 23 can also wrap the implanting part 243 of the sensor 24, and the implanting part 243 of the sensor 24 can also pierce into the living body 30 with the puncture needle 23, which is not strictly limited in the present application.

[0507] FIG. 26 is a partial cross-sectional view of an embodiment of the sensor assembly 20 shown in FIG. 23, along the line G-G. FIG. 26 shows an assembly schematic of an embodiment of the sensor 24, the needle hub 22, the puncture needle 23, and the sealed bottle 29.

[0508] As shown in FIG. 26, the sealed bottle 29 can be used to protect the puncture needle 23 from microbial contamination. The sealed bottle 29 has a hollow cavity. For example, the sealed bottle 29 can include a bottle body 291 and a bottle plug 292. The bottle body 291 has an internal placing space 2901 (hollow cavity). The placing space 2901 can extend along the axial direction of the bottle body 291, and pass through both ends of the bottle body 291 to form a first opening 2911 at one end of the bottle body 291 and a second opening 2912 at the other end. The bottle plug 292 can be detachably fixed to one end of the bottle body 291 to seal the first opening 2911. The other end of the bottle body 291 is close to the needle hub 22 and is fixed to the guide portion 225 of the needle hub 22.

[0509] In some embodiments, part of the sensor 244 and the puncture end 231 of the puncture needle 23 can be located in the hollow cavity of the sealed bottle 29. For example, the puncture needle 23 and the sensor 24 located in the puncture needle 23 can enter the placing space 2901 through the second opening 2912. The other end of the bottle body 291 can be provided with threads in the placing space 2901. The circumferential surface 2251 of the guide portion 225 of the needle hub 22 can be provided with threads matching the threads of the bottle body 291. In this way, the other end of the bottle body 291 can be fixedly connected to the guide portion 225 of the needle hub 22 by threads. It can be understood that the bottle plug 292, the threads in the placing space 2901, and the threads of the circumferential surface 2251 of the guide portion 225 can be used to seal, dustproof, and prevent contamination of the placing space 2901.

[0510] In other embodiments, the guide portion 225 of the needle hub 22 and the bottle body 291 can be locked by a slanted chute.

[0511] In some embodiments, the sealed bottle 29 can further include a ratchet 293. The ratchet 293 can be protruded on the outer side of the sealed bottle 29. Exemplarily, the number of the ratchets 293 can be one or more. When the number of the ratchets 293 is more than one, the plurality of ratchets 293 can be arranged around the circumference of the sealed bottle.

[0512] In other embodiments, the bottle body 291 and the bottle plug 292 can be an integral structure and not detachable.

[0513] FIG. 27 is an assembly view of an embodiment of the electrical connection assembly 26 and the battery assembly 25 shown in FIG. 24.

[0514] As shown in FIG. 27, the electrical connection assembly 26 can include a printed circuit board (PCB) 261 and an electrical connector 262. The electrical connector 262 is electrically connected to the PCB 261. Exemplarily, the PCB 261 includes a first surface 2611 and a second surface 2612 arranged oppositely. The electrical connector 262 can be fixed to the second surface 2612 of the PCB 261 and electrically connected to the PCB 261. The electrical connector 262 can be used for transmitting electrical signals between the PCB 261 and the sensor 24.

[0515] It can be understood that the PCB 261 can be provided with electronic components (not shown in the figure) such as chips, capacitors, resistors, near field communication (NFC) components, or Bluetooth components.

[0516] Exemplarily, the battery assembly 25 can include a first battery 251, a second battery 252, a first positive electrode sheet 253, a first negative electrode sheet 254, a second positive electrode sheet 255, a second negative electrode sheet 256, and a switch magnet 257. One end of the first positive electrode sheet 253 is fixedly connected to the PCB 261 and electrically connected to the PCB 261. The other end of the first positive electrode sheet 253 is fixedly connected to the first battery 251 and electrically connected to the positive electrode of the first battery 251.

One end of the second negative electrode sheet 256 is fixedly connected to the PCB 261 and electrically connected to the PCB 261.

[0517] Exemplarily, the switch magnet 257 can be movably connected between the other end of the first negative electrode sheet 254 and the other end of the second positive electrode sheet 255, for controlling the electrical conduction between the first negative electrode sheet 254 and the second positive electrode sheet 255. When the switch magnet 257 connects the first negative electrode sheet 254 and the second positive electrode sheet 255 at the same time, the first negative electrode sheet 254 and the second positive electrode sheet 255 can be electrically conducted through the switch magnet 257, and the current can pass through the switch magnet 257, so that the battery assembly 25 can normally transmit the current to the circuit board 261. When the switch magnet 257 disconnects the first negative electrode sheet 254 and the second positive electrode sheet 255, the first negative electrode sheet 254 and the second positive electrode sheet 255 are disconnected, and the battery assembly 25 cannot transmit the current to the circuit board 261. Details will be described below with reference to the accompanying drawings, how to realize the connection and disconnection between the switch magnet 257 and the first negative electrode sheet 254 and the second positive electrode sheet 255.

[0518] It can be understood that the application does not limit the positive and negative electrode sheets electrically connected by the switch magnet 257, and in other embodiments, the positions of the first positive electrode sheet 253 and the first negative electrode sheet 254 can be interchanged. The positions of the second positive electrode sheet 255 and the second negative electrode sheet 256 can be interchanged.

[0519] Exemplarily, the first positive electrode sheet 253, the first negative electrode sheet 254, the second positive electrode sheet 255 and the second negative electrode sheet 256 can be made of conductive steel sheets. The switch magnet 257 has an attractive force with the first negative electrode sheet 254 and the second positive electrode sheet 255.

[0520] Exemplarily, the switch magnet 257 can be composed of one or two magnets.

[0521] FIG. 28 is an assembly schematic view of an embodiment of the sensor 24, the needle seat 22, the puncture needle 23 and the electrical connection assembly 26 shown in FIG. 24.

[0522] As shown in FIGS. 27 and 28, the connecting portion 241 of the sensor 24 is connected to the electrical connector 262 and is electrically connected to the electrical connector 262. When the switch magnet 257 connects the first negative electrode sheet 254 and the second positive electrode sheet 255 at the same time, the first battery 251 and the second battery 252 can be electrically connected to the circuit board 261, and the circuit board 261 is electrically connected through the electrical connector 262 and the connecting portion 241 of the sensor 24. In this way, the first battery 251 and the second battery 252 can supply power to the sensor 24. In other words, the switch magnet 257 can be used to control the on-off of the sensor 24.

[0525] The first flange 2012 is exemplarily fixedly connected to the top surface 2014 of the plate portion 2011. The first flange 2012 is arranged around the first through hole 2016. The first flange 2012 is substantially annular, and a diameter of the annular shape can be smaller than a diameter of the plate portion 2011.

[0526] The second flange 2013 is exemplarily fixedly connected to the bottom surface 2015 of the plate portion 2011. The second flange 2013 can be arranged around the first through hole 2016.

[0527] The diameter of the first flange 2012 can be smaller than the diameter of the second flange 2013. In this way, during assembly of the gasket 201, the top surface and the bottom surface of the plate portion 2011 can be distinguished according to the diameters of the two structures, so as to determine the installation direction. In other embodiments, the diameter of the first flange 2012 can also be greater than the diameter of the second flange 2013, or the diameter of the first flange 2012 can also be equal to the diameter of the second flange 2013.

The guide portion 225 of the needle seat 22 can pass through the first through hole, the second through hole 2111 and the third through hole 2711 to extend out of the lower cover 27. Exemplarily, the first flange 2012 of the gasket 201 is located in the first limiting groove 5212101 of the upper cover 21, and the second flange 2013 is located in the second limiting groove 5212701 of the lower cover 27. It can be understood that the gasket 201 functions to form a bacteria-proof package together with other structural members, and to seal the part of the sensor 24 implanted under the skin.

[0539] In some embodiments, the sealing portion 224 of the needle seat 22 can abut between the limiting portion 223 of the needle seat 22 and the upper cover plate 211 of the upper cover 21. The sealing portion 224 can be used for sealing between the needle seat 22 and the upper cover 21. Exemplarily, the sealing portion 224 can be a silicone ring. The silicone ring can be fixedly connected to the limiting portion 223 of the needle seat 22 by means of adhesive bonding.

[0540] In some embodiments, the gasket 201 can further include a sealing ring 2017. The sealing ring 2017 can be fixedly connected to the side of the plate portion 2011 of the gasket 201 facing the second flange 2013, and is arranged around the first through hole. The sealing ring 2017 can be located inside the second flange 2013. The sealing ring 2017 can be exposed to the lower cover 27 through the third through hole 2711 of the lower cover 27, and abuts between the plate portion 2011 of the gasket 201 and the sealed bottle 29. The sealing ring 2017 can be used to form a sealed dustproof structure with the sealed bottle 29, and to achieve bacteria-proofing. In other embodiments, the sealing ring 2017 can also be fixed to the sealed bottle 29.

[0541] Exemplarily, the seal between the sensor 24 and the gasket 201 and the upper cover 21 can be achieved by glue dispensing. The sealing interface of the neck of the sensor 24 (the position where the fixing portion 242 is located) is composed of the upper cover 21, the gasket 201 and the glue.

[0542] Exemplarily, the fixation and seal between the gasket 201 and the upper cover 21 and the lower cover 27 can be achieved by glue dispensing.

[0543] Exemplarily, the fixation and seal between the first side plate 212 of the upper cover 21 and the second side plate 272 of the lower cover 27 can also be achieved by glue dispensing.

[0544] FIG. 30 is a partial cross-sectional view of one embodiment of the physiological sign detection device 100 shown in FIG. 2 at F-F.

[0545] As shown in FIG. 30, the sensor assembly 20 can be fixed to the bracket 3 and located on the side of the bracket 3 away from the top wall 12 of the lower housing 1. The axial direction of the sensor assembly 20 can coincide with the axial direction of the bracket 3. Exemplarily, the sensor assembly 20 can be installed in the second accommodating space 302 of the bracket 3. The upper cover 21 of the sensor assembly 20 is located between the lower cover 27 and the bottom plate 32 of the bracket 3.

[0546] In some embodiments, the clamping hook of the fifth elastic arm 38 of the bracket 3 can be clamped to the lower cover 27 of the sensor assembly 20. In the axial direction, the clamping hook of the fifth elastic arm 38 of the bracket 3 is at least partially located on the side of the lower cover 27 of the sensor assembly 20 away from the upper cover 21. It can be understood that the clamping hook of the fifth elastic arm 38 of the bracket 3 can be used to limit the sensor assembly 20 in the axial direction, reducing the risk of the sensor assembly 20 being loosened in the axial direction before being launched. For example, the second magnet 83 of the shell cap assembly 8 has an attractive force to the switch magnet 257 of the sensor assembly 20 when the upper housing 81 is removed, and by providing the fifth elastic arm 38, the risk of the sensor assembly 20 being attracted and falling off by the attractive force of the second magnet 83 can be reduced.

[0547] It can be understood that when the sensor assembly 20 is not launched, the side plate 31 of the bracket 3 abuts against the fifth elastic arm 38, so that the fifth elastic arm 38 is in a clamped state with respect to the sensor assembly 20.

[0548] In some embodiments, the needle holder 4 clamps the needle holder 22. In this case, the needle holder 22 can extend through the mounting hole 321 of the bracket 3 to the needle holder 4. The clamping portion 222 of the needle holder 22 is clamped by the clamping hook of the first cantilever arm 43, so that the needle holder 22 can move synchronously with the needle holder 4. When the number of the first cantilever arm 43 is multiple, the clamped needle holder 22 can be uniformly stressed. When the bracket 3 moves in the implantation direction, the bracket 3 can push the sensor assembly 20 to move in the implantation direction, so that the adhesive 28 of the sensor assembly 20 can be adhered to the living body. And the bracket 3 pushes the needle holder 22 to the living body through the needle holder 4, so that the puncture needle 23 can be inserted into the living body. When the needle holder 4 moves in the opposite direction of the implantation direction, the first cantilever arm 43 drives the puncture needle 23 to move in the opposite direction of the implantation direction through the needle holder 22, so that the puncture needle 23 can be separated from the living body.

[0549] In some embodiments, the center of the mounting hole 321 of the bracket 3 is located at or near the axis of the physiological sign detection device 100, and the multiple first cantilever arms 43 are arranged around the axis of the physiological sign detection device 100, so that when the needle holder 22 of the sensor assembly 20 clamps the first cantilever arm 43 through the mounting hole 321, the extension direction of the puncture needle 23 is located at or near the axis of the physiological sign detection device 100, so that when the bracket 3 pushes the sensor assembly 20 to move in the implantation direction, the puncture needle 23 can be more concentratedly stressed, which helps to reduce the user's pain of insertion.

[0550] FIG. 31a is a structural schematic diagram of an embodiment of the shell cap assembly 8 shown in FIG. 3. FIG. 31b is an exploded schematic diagram of an embodiment of the shell cap assembly 8 shown in FIG. 30.

[0551] As shown in FIGS. 31a and 31b, the shell cap assembly 8 can include an upper shell 81, a desiccant 82, and a second magnet 83. The desiccant 82 can be made of a material with adsorption function, for example. The desiccant 82 is used to adsorb moisture, so that the humidity inside the physiological sign detection device 100 can be maintained within a suitable range.

[0552] FIG. 32 is a structural schematic diagram of an embodiment of the upper shell 81 shown in FIG. 31b.

[0553] As shown in FIG. 32, the upper shell 81 can include a bottom wall 811, a side wall 812, a pawl 813, and a limiting member 814. The side wall 812 of the upper shell 81 surrounds and is connected to the periphery of the bottom wall 811 of the upper shell 81. The pawl 813 and the side wall 812 of the upper shell 81 are fixedly connected to the same side of the bottom wall 811 of the upper shell 81. The pawl 813 is located inside the side wall 812 of the upper shell 81. The upper shell 81 can be generally cylindrical.

[0554] Exemplarily, one end of the pawl 813 can be fixed to the bottom wall 811 of the upper housing 81, and the other end of the pawl 813 away from the bottom wall 811 of the upper housing 81 is provided with a clasp. The clasp of the pawl 813 can be formed by a smooth protrusion from one side to the other side. The number of the pawls 813 can be one or more, and the plurality of pawls 813 are arranged at intervals around the axis of the upper housing 81. Exemplarily, the number of the pawls 813 is two, and the two pawls 813 have the same extension direction.

[0555] Exemplarily, the limiting member 814 can be located outside the pawl 813 and arranged at intervals with the pawl 813. One end of the limiting member 814 is fixed to the bottom wall 811 of the upper housing 81. The number of the limiting member 814 can be one or more, and the plurality of limiting members 814 are arranged at intervals around the axis of the upper housing 81. The other end of the limiting member 814 away from the upper housing 81 is provided with a clasp, and the clasp can be towards the bottom wall 811. Exemplarily, the number of the limiting member 814 is four.

[0556] In some embodiments, the upper housing 81 can be a one-piece structure.

[0557] FIG. 33 is a cross-sectional view of one embodiment of the shell cap assembly 8 shown in FIG. 31a at H-H. FIG. 34 is a cross-sectional view of one embodiment of the shell cap assembly 8 shown in FIG. 31a at I-I.

[0558] As shown in FIG. 33 and FIG. 34, the desiccant 82 can be provided with a first mounting groove 821. The opening of the first mounting groove 821 can be towards the side away from the bottom wall 811 of the upper housing 81. The second magnet 83 can be mounted in the first mounting groove 821.

[0559] In some embodiments, the desiccant 82 can be clamped to the upper housing 81. Exemplarily, the side of the desiccant 82 can be provided with a boss 822. The clasp of the limiting member 814 can be clamped with the boss 822 of the desiccant 82. In the axial direction of the upper housing 81, the boss 822 can be partially located between the clasp of the limiting member 814 and the bottom wall 811 of the upper housing 81. In this way, the sliding of the desiccant 82 in the axial direction of the upper housing 81 can be avoided.

[0560] In some embodiments, the desiccant 82 can also be fixedly connected to the upper housing 81 by means of gluing. As shown in FIG. 32, the bottom wall 811 of the upper housing 81 can be provided with a glue groove 8111, and the opening 101 of the glue groove 8111 is towards the side wall 812 of the upper housing 81. The glue groove 8111 can be used to accommodate adhesive. When the desiccant 82 is fixedly connected to the upper housing 81 by means of gluing, the desiccant 82 and the bottom wall 811 of the upper housing 81 can also have an adhesive layer therebetween.

[0561] It can be understood that the connection between the desiccant 82 and the upper shell 81 can include both the clamping of the limiting member 814 and the gluing, or either one of them.

[0562] In some embodiments, the desiccant 82 can be provided with a second mounting groove 823, and the pawl 813 of the upper shell 81 can be located in the second mounting groove 823.

[0563] In some embodiments, the inner wall surface of the side wall 812 of the upper shell 81 can be provided with a clamping thread. The clamping thread is located on the side of the side wall 812 of the upper shell 81 away from the bottom wall 811 of the upper shell 81. The clamping thread can be used to fixedly connect the lower shell 1. Details will be described below in conjunction with the drawings.

[0564] In some embodiments, the upper shell 81 can further include a sealing strip 815. The sealing strip 815 can be fixedly connected to the inner wall surface of the side wall 812 of the upper shell 81 (the sealing strip 815 and the side wall 812 are distinguished by a dashed line in FIG. 33), and together with the side wall 812 of the upper shell 81 enclose a sealing groove 8101. The opening 101 of the sealing groove 8101 faces away from the bottom wall 811 of the upper shell 81. Exemplarily, the sealing strip 815 can be an integral structure with the side wall 812 of the upper shell 81.

[0565] In some embodiments, the upper shell 81 can further include a second stop structure 816. The second stop structure 816 can be fixedly connected to the inner wall surface of the side wall 812 of the upper shell 81. Exemplarily, the second stop structure 816 can be a thread. The pitch of the thread of the second stop structure 816 is equal to the pitch of the clamping thread.

[0566] Exemplarily, along the direction of the bottom wall 811 of the upper shell 81 towards the side wall 812 of the upper shell 81, the second stop structure 816, the sealing strip 815 and the clamping thread can be arranged in sequence.

[0567] FIG. 35 is a partial cross-sectional view of an embodiment of the physiological sign detection device 100 shown in FIG. 2 at B-B.

[0568] As shown in FIG. 27 and FIG. 35, the upper shell 81 is detachably connected to the lower shell 1. The upper shell 81 can cover the opening 101 of the lower shell 1. The upper shell 81 and the lower shell 1 can constitute the housing of the physiological sign detection device 100. It can be understood that the upper shell 81 and the lower shell 1 in FIG. 35 are detachable as an example, and in other embodiments, they can also be integral and not detachable.

[0569] As shown in FIG. 34 and FIG. 35, the upper housing 81 and the lower housing 1 can be fixedly connected by a threaded engagement. Illustratively, an outer surface of an end of the sidewall 11 of the lower housing 1 distal to the bottom wall 811 of the lower housing 1 can be threaded. The threads of the lower housing 1 can match the press-fit threads of the upper housing 81, and the upper housing 81 can be fixedly connected to the lower housing 1 by a threaded engagement.

[0570] As shown in FIG. 35, the first magnet 9, the switch magnet 257, and the second magnet 83 are oppositely arranged in the axial direction of the physiological sign detection device 100. Illustratively, the first magnet 9 can be located between the switch magnet 257 and the bracket 3. The first magnet 9 can be configured to provide an attractive force or a repulsive force to the switch magnet 257, such that the switch magnet 257 can be disconnected from the first negative electrode plate 254 and the first positive electrode plate 253. The second magnet 83 can be configured to provide an attractive force or a repulsive force to the switch magnet 257, such that the switch magnet 257 can be disconnected from the first negative electrode plate 254 and the first positive electrode plate 253 (in combination with FIG. 27). It can be appreciated that whether the first magnet 9 and the second magnet 83 provide an attractive force or a repulsive force to the switch magnet 257 depends on the relative position relationship between the switch magnet 257 and the first negative electrode plate 254 and the first positive electrode plate 253.

[0571] Illustratively, the first negative electrode plate 254 and the first positive electrode plate 253 are located on a side of the switch magnet 257 closer to the first magnet 9. In this case, the first magnet 9 can be configured to provide a repulsive force to the switch magnet 257, such that the switch magnet 257 can be disconnected from the first negative electrode plate 254 and the first positive electrode plate 253. The second magnet 83 can be configured to provide an attractive force to the switch magnet 257, such that the switch magnet 257 can be disconnected from the first negative electrode plate 254 and the first positive electrode plate 253.

[0572] It can be understood that by arranging the first magnet 9, the switching magnet 257 and the second magnet 83, when the shell cap assembly 8 is fixed to the lower shell 1, the first magnet 9, the switching magnet 257 and the second magnet 83 are oppositely arranged, the first magnet 9 and the second magnet 83 act on the switching magnet 257, so that the switching magnet 257 can be disconnected from the first negative electrode sheet 254 and the first positive electrode sheet 253 when the physiological parameter detection device 100 is stored (the physiological parameter detection device 100 is in an unused state), so as to make the sensor 24 be powered off. By physically turning on and off the power, the storage power consumption of the physiological parameter detection device 100 is reduced, and the product endurance is improved. When the physiological parameter detection device 100 is used, the shell cap assembly 8 is removed, and the support 3 also leaves the user's tissue after the sensor assembly 20 is emitted. At this time, the first magnet 9 and the second magnet 83 do not act on the switching magnet 257, and the switching magnet 257 has an attractive force between the first negative electrode sheet 254 and the second positive electrode sheet 255, so that the switching magnet 257 can simultaneously contact and connect the first negative electrode sheet 254 and the second positive electrode sheet 255 under the action of the attractive force, and electrically connect the first negative electrode sheet 254 and the second positive electrode sheet 255, so as to realize the electrical conduction between the first battery 251 and the second battery 252, and the sensor 24 is powered on. The battery assembly 25 can supply power to the sensor 24 and other electronic devices on the circuit board 261, and the sensor assembly 20 can work normally.

[0573] In other embodiments, when the force of the first magnet 9 or the second magnet 83 on the switching magnet 257 meets the disconnection requirement, only one of the first magnet 9 and the second magnet 83 can be arranged. It can be understood that when only one of the first magnet 9 and the second magnet 83 is arranged, the structure of the support 3 or the desiccant 82 can be changed accordingly. Compared with the scheme of arranging only one of the first magnet 9 and the second magnet 83, arranging both the first magnet 9 and the second magnet 83 acts on the switching magnet 257 to make the sensor 24 be powered off, and the force of the first magnet 9 and the second magnet 83 on the switching magnet 257 can be greater, which is beneficial to ensure that the sensor 24 is powered off when the physiological parameter detection device 100 is in an unused state.

[0574] In some embodiments, the lower shell 1 can further include a sealing rib 17. The sealing rib 17 can be fixedly connected to one side of the side wall 11 of the lower shell 1 away from the bottom wall 811 of the lower shell 1. When the lower shell 1 is fixedly connected to the upper shell 81, the sealing rib 17 is located in the sealing groove 8101 of the upper shell 81 and abuts against the wall surface of the sealing groove 8101. In other words, the sealing rib 17 and the sealing groove 8101 are interference fit to realize a sealed interface. It can be understood that the interference fit of the sealing rib 17 and the sealing groove 8101 can reduce the gap between the upper shell 81 and the lower shell 1, and reduce the entry of external water vapor into the physiological parameter detection device 100, which affects the function of the sensor assembly 20.

[0575] In some embodiments, the upper housing 81 and the lower housing 1 can be made of materials with low water vapor permeability, such as polypropylene (PP) and high-density polyethylene (HDPE).

[0576] Understandably, the storage conditions of sensor 24 have certain humidity requirements and need to be stored in a relatively dry environment for a long time. This application achieves a sealed interface through the interference fit of sealing rib 17 and sealing groove 8101; the upper housing 81 and lower housing 1 can be made of materials with low water vapor permeability; and a desiccant 82 is placed inside the upper housing 81. This allows for a relatively dry storage environment within the physiological sign detection device 100. This is beneficial for the long-term preservation of sensor component 20. The sensor component 20 within the physiological sign detection device 100 of this application is less prone to aging, resulting in a longer shelf life for the physiological sign detection device 100.

[0577] In other embodiments, the upper housing 81 and the lower housing 1 can also be sealed by a sealing O-ring.

[0578] In some embodiments, when the top of the physiological sign detection device 100 (i.e., the end where the top wall 12 of the lower housing 1 is located) falls downwards, the lower housing 1 moves closer to the upper housing 81, and the lower housing 1 and the base 5 are prone to relative movement, causing the hook of the second spring arm 56 to be pushed outward by the push block 15 of the lower housing 1, causing the hook to be in a disengaged state inside. The first elastic member 2 applies a resisting elastic force to the bracket 3. In this case, after the user unscrews the shell cap assembly 8, the bracket 3 with the sensor assembly 20 will be directly launched, and the product cannot be used normally.

[0579] In some embodiments, the first stop structure 18 contacts the second stop structure 816. The second stop structure 816 may be disposed opposite to the first stop structure 18 in the axial direction of the upper housing 81. The second stop structure 816 of the upper housing 81 is located on the side of the first stop structure 18 of the base 5 away from the bottom wall 811 of the upper housing 81, that is, the second stop structure 816 may be located on the side of the first stop structure 18 near the top wall 12 of the lower housing 1. It is understood that the first stop structure 18 and the second stop structure 816 may serve as blocking members 91, used to prevent the base 5 from moving relative to the lower housing 1 along the axial direction of the physiological characteristic detection device 100 when the physiological characteristic detection device 100 is in an unused state. When the top of the physiological sign detection device 100 falls downwards, the first stop structure 18 and the second stop structure 816 can act as a fall-prevention trigger latch (blocking member 91), which restricts the large relative movement of the base 5 and the lower housing 1 along the axial direction, so that the physiological sign detection device 100 will not be triggered by falling or vibration.

[0580] In some embodiments, the first stop structure 18 contacts the second stop structure 816, which can be understood as that when the top of the physiological sign detection device 100 falls downwards, the first stop structure 18 abuts against the second stop structure 816. When not subjected to impact, there can be a small gap between the first stop structure and the second stop structure 816 in the axial direction of the upper housing 81 for assembly. For example, the gap between the first stop structure and the second stop structure 816 in the axial direction of the upper housing 81 can be less than the trip distance. The trip distance refers to the movement trip distance of the lower housing 1 relative to the base 5 in the axial direction of the upper housing 81, at which the bracket 3 is triggered. Exemplarily, when the trip distance is 5 mm, the gap between the first stop structure and the second stop structure 816 in the axial direction of the upper housing 81 can be less than 4 mm.

[0581] In some embodiments, the first stop structure 18 and the second stop structure 816 can be threads that are matched with each other. It can be understood that the thread structure is simple and has low manufacturing difficulty, and setting the first stop structure 18 and the second stop structure 816 as threads is conducive to reducing production cost and simplifying the mechanism.

[0582] In some embodiments, the pitch of the thread of the first stop structure 18 and the pitch of the thread of the second stop structure 816 are the same. The pitch of the thread of the first stop structure 18 and the pitch of the thread of the second stop structure 816 can both be the same as the pitch of the engagement thread. In this way, when the upper housing 81 is screwed to the lower housing 1, the first stop structure 18 and the second stop structure 816 can be better in contact and cooperation. Exemplarily, the thread of the first stop structure 18 can be a continuous circle or can be several spaced threads. When the first stop structure 18 is several spaced threads, the pitches of the several threads are the same.

[0583] In some embodiments, the sealing bottle 29 can abut against the bottom wall 811 of the upper housing 81. It can be understood that when the bottom of the physiological sign detection device 100 (i.e., the end where the bottom wall 811 of the upper housing 81 is located) falls downwards, the upper housing 81 has a tendency to move close to the lower housing 1, and the sealing bottle 29 can abut against the bottom wall 811 of the upper housing 81 to limit the movement distance of the upper housing 81 in the axial direction, so as to avoid the upper housing 81 abutting against the base 5 and causing the catch of the second elastic arm 56 to trip.

[0584] FIG. 36a is a schematic view of an embodiment of the upper housing 81. FIG. 36b is a schematic view of an embodiment of the lower housing 1. FIG. 36c is a schematic view of another embodiment of the lower housing 1 shown in FIG. 36b from another angle.

[0585] As shown in FIG. 35, FIG. 36a, FIG. 36b, and FIG. 36c, the screw thread of the upper shell 81 can be multi-start. In this way, the number of turns of the screw thread can be reduced. The starting position of any one of the multi-start screw threads can be the starting position of the screwing.

[0586] It can be understood that in some embodiments of the present application, the switch magnet 257 and the second magnet 83 need to be oppositely arranged in the axial direction of the physiological sign detection device 100 to ensure that the magnetic attraction force works so that the product can normally turn on and off. Therefore, the positions of the upper shell 81 and the lower shell 1 after being screwed need to be relatively fixed, and the positions of the upper shell 81 and the lower shell 1 after being screwed need to be designed to prevent mistakes. The screw threads of the upper shell 81 and the lower shell 1 need to have a mistake-proof function, that is, the upper shell 81 is in a fixed position after each screwing, ensuring that the second magnet 83 on the bottle cap is aligned with the switch magnet 257. In other embodiments, when a Hall switch is used as a switching scheme, the Hall magnet needs to be fixed on the upper shell 81, and the upper shell 81 also needs to have a fixed position.

[0587] In some embodiments, two multi-start screw threads with different starting heights can be used for mistake-proof design. For example, using a double-start screw thread, the two screw threads on the lower shell 1 are designed to have different starting heights, forming a coarse screw thread engagement opening 104 and a fine screw thread engagement opening 105. The screw thread of the upper shell 81 can include a coarse screw thread 817 and a fine screw thread 818, and the coarse screw thread 817 cannot engage with the fine screw thread engagement opening 105, thereby playing a mistake-proof role. Ensure that the position of the upper shell 81 after being screwed is fixed in the case of multi-start screw threads, thereby ensuring that the second magnet 83 of the upper shell 81 is in a fixed position and oppositely arranged with the switch magnet 257.

[0588] It can be understood that compared with a single-start screw thread, a multi-start screw thread has greater structural strength, and the starting height of the multi-start screw thread can be designed for mistake-proof design.

[0589] FIG. 37 is an assembly schematic view of an embodiment of the upper shell 81 and the sealed bottle 29 shown in FIG. 35. FIG. 38 is a partial cross-sectional schematic view of an embodiment of the physiological sign detection device 100 at J-J shown in FIG. 2.

[0590] As shown in FIG. 26, FIG. 37 and FIG. 38, the pawl 813 of the upper housing 81 is arranged to cooperate with the ratchet 293 of the sealing bottle 29. The screw thread of the upper housing 81 has the same screw direction as the inner thread of the sealing bottle 29 (please refer to FIG. 26, the thread of the sealing bottle 29 is used to connect the needle seat 22). During the screwing of the upper housing 81 relative to the lower housing 1 (moving in the direction shown by the dotted arrow in FIG. 37), the pawl 813 is in sliding connection with the ratchet 293. That is, during the screwing of the upper housing 81 relative to the lower housing 1, the pawl 813 does not push the ratchet 293 to move, so as to avoid the loosening of the sealing bottle 29 relative to the needle seat 22 when the upper housing 81 is assembled to the lower housing 1. During the disassembly of the upper housing 81 from the lower housing 1 (moving in the direction shown by the solid arrow in FIG. 37), the pawl 813 clamps the ratchet 293 and pushes the sealing bottle 29 to rotate. Since the sealing bottle 29 is screwed to the needle seat 22 (please refer to FIG. 26), the sealing bottle 29 is screwed off from the needle seat 22, so that the sealing bottle 29 is separated from the needle seat 22. In this embodiment, the number of turns of the inner thread of the upper housing 81 can be greater than the number of turns of the inner thread of the sealing bottle 29, so that the sealing bottle 29 can be separated from the needle seat 22 before the upper housing 81 is separated from the lower housing 1.

[0591] In this embodiment, the upper housing 81 is screwed to the lower housing 1, the sealing bottle 29 is screwed to the needle seat 22, the pawl 813 of the upper housing 81 cooperates with the ratchet 293 of the sealing bottle 29, and the upper housing 81 can push the sealing bottle 29 to separate from the needle seat 22 when the upper housing 81 is separated from the lower housing 1, so that the puncture needle 23 and the sensor 24 are exposed, which helps to simplify the operation steps of the physiological sign detection device 100 and improve the user experience.

[0592] The cooperation of the components of the physiological sign detection device 100 during use will be described below with reference to the accompanying drawings.

[0593] FIG. 39 is a partial cross-sectional view of an embodiment of the physiological sign detection device 100 at B-B during use, as shown in FIG. 2. FIG. 40 is a partial cross-sectional view of an embodiment of the physiological sign detection device 100 at B-B during use, as shown in FIG. 2. FIG. 41 is a partial cross-sectional view of an embodiment of the physiological sign detection device 100 at B-B during use, as shown in FIG. 2.

[0594] As shown in FIG. 35, FIG. 39, FIG. 40 and FIG. 41, FIG. 35 is a schematic view of the physiological sign detection device 100 before use, i.e., the physiological sign detection device 100 is in an unused state (storage state). FIG. 39 to FIG. 41 are schematic views of the physiological sign detection device 100 in different time during use. In this embodiment, FIG. 39 is a schematic view of the bracket 3 in a triggered position. FIG. 40 is a schematic view of the needle extraction seat 4 in a triggered position. FIG. 41 is a schematic view of the needle extraction action after the emission is completed.

[0595] As shown in FIG. 35 and FIG. 39, when the physiological sign detection device 100 needs to be used, the shell cap assembly 8 is removed, the sealing bottle 29 is removed together with the shell cap assembly 8, the abutting end 502 of the base 5 abuts against the user's tissue, the base 5 is not moved relative to the user's tissue, and after a downward pressure is applied to the lower housing 1, the lower housing 1 moves downward, the push block 15 of the lower housing 1 pushes the second elastic arm 56 of the base 5, the clamping hook of the second elastic arm 56 is pushed outward by the push block 15 of the lower housing 1, exits the first clamping space 303 of the support 3, and the support 3 is released.

[0596] In the embodiment, the base 5 releases the limit of the support 3 through the cooperation of the push block 15 and the second elastic arm 56, so that the support 3 is separated from the base 5 under the elastic force of the first elastic member 2. When the lower housing 1 moves in the downward direction, the push block 15 gradually pushes the second elastic arm to move outward of the side plate 31 of the support 3 and compresses the first elastic member 2, and when the clamping hook of the second elastic arm 56 is separated from the first clamping space 303, the support 3 moves in the downward direction under the elastic force of the first elastic member 2. The limit of the support 3 of the physiological sign detection device 100 and the release mechanism thereof have a simple structure and a compact arrangement, and the transmission speed between the lower housing 1 and the base 5 is fast.

[0597] As shown in FIG. 39 and FIG. 40, the first elastic member 2 abuts against the lower housing 1 and the spring seat 7, the spring seat 7 is fixedly connected to the support 3, the support 3 is released, the first elastic member 2 is also released, the first elastic member 2 can apply a downward thrust to the spring seat 7, and then push the spring seat 7 and the support 3 to move downward, the sensor assembly 20 is fixed to the support 3, so that the support 3 drives the sensor assembly 20 to approach the user's tissue, the puncture needle 23 of the sensor assembly 20 penetrates into the user's tissue, and the adhesive member 28 of the sensor assembly 20 is attached to the user's skin.

[0598] For example, the flange 34 of the support 3 is located on the side of the adhesive member 28 of the sensor assembly 20 away from the abutting end 502 of the base 5. The flange 34 can be substantially flush with the end face of the lower side plate 33 of the support 3 close to the abutting end 502. When the sensor assembly 20 is launched, the flange 34 can press the adhesive member 28 to the user's skin. It can be understood that, compared with the technical solution without the flange 34, the flange 34 can increase the connection area of the support 3 and the user's skin, reduce the pain of the user when using the physiological sign detection device 100, and improve the user experience.

[0599] It can be understood that, considering the manufacturing process tolerance, the flange 34 of the support 3 slightly protrudes from the end face of the lower side plate 33 of the support 3 close to the abutting end 502.

[0600] As shown in FIG. 40 and FIG. 41, during the downward movement of the bracket 3, the inner side of the upper side wall 51 of the base 5 can be provided with a trigger groove 511, the opening of the trigger groove 511 facing the inner side of the upper side wall 51 of the base 5. When the fourth elastic arm 37 of the bracket 3 moves to the trigger groove 511, the fourth elastic arm 37 is released and opens outward, and the needle holder 4 loses the constraint and is released. The second elastic member 6 can exert an upward abutting force on the needle holder 4.

[0601] The limiting buckle 221 of the needle holder 22 of the sensor assembly 20 is clamped by the first cantilever arm 43 of the needle holder 4. When the needle holder 4 is subjected to an upward force, the first cantilever arm 43 of the needle holder 4 can provide an upward pulling force to the needle holder 22. The needle holder 4 and the needle holder 22 are subjected to the force of the second elastic member 6 and move upward, so that the first cantilever arm 43 will pull out the puncture needle 23 from the user's tissue, the sensor 24 remains in the user's tissue, and the needle extraction action is completed. The upper cover 21, the battery assembly 25, the electrical connection assembly 26, the lower cover 27, the adhesive 28, and the gasket 201 of the sensor assembly 20 can constitute a transmitter (in combination with FIG. 24). After the needle extraction action is completed, the transmitter remains on the user's tissue and can be used to transmit the user's physiological target substance data collected by the sensor 24 to a terminal device.

[0602] The fifth elastic arm 38 of the bracket 3 is spaced apart from the base 5 after the bracket 3 moves to the abutting end 502 of the base 5. At this time, the base 5 does not tighten the fifth elastic arm 38, that is, the fifth elastic arm 38 is released. After the needle extraction action is completed, the user removes the shell 1 and other devices. The fifth elastic arm 38 is separated from the lower shell 1 of the sensor assembly 20 with the action of the user removing it, and the sensor assembly 20 is released.

[0603] Exemplarily, the first elastic member 2, the spring seat 7, and the bracket 3 can constitute a pushing mechanism of the physiological sign detection device 100. The lower shell 1, the base 5, and the bracket 3 can constitute a trigger mechanism of the physiological sign detection device 100. The needle holder 4, the second elastic member 6, the bracket 3, the needle holder 22, and the puncture needle 23 can constitute a needle extraction mechanism of the physiological sign detection device 100. The trigger mechanism can serve as a switch for the use of the physiological sign detection device 100, to control whether to launch the sensor 24. The pushing mechanism can be used to push the sensor assembly 20, and the puncture needle 23 brings the sensor 24 into the tissue of the human body. The needle extraction mechanism can be used to realize the function of pushing the puncture needle 23 to penetrate the skin and then extracting the puncture needle 23.

[0604] It can be understood that after the sensor assembly 20 is pushed into place, the pushing mechanism is subjected to the force of two springs (the first elastic member 2 and the second elastic member 6). Due to the characteristic of the springs that they oscillate back and forth in the axial direction, the pushing mechanism also oscillates with the springs, and the oscillation causes greater damage to the skin wound after implantation. Therefore, a locking mechanism is needed to prevent the pushing mechanism from returning, eliminate the oscillation caused by the springs, improve the implantation experience, and reduce the damage to the wound after implantation.

[0605] In some embodiments, the base 5 can also participate in the construction of the needle extraction mechanism of the physiological sign detection device 100.

[0606] FIG. 42 is a partial cross-sectional view of an embodiment of the physiological sign detection device 100 shown in FIG. 2 at K-K before use. FIG. 43 is a partial cross-sectional view of an embodiment of the physiological sign detection device 100 shown in FIG. 2 at K-K during use. FIG. 44a is a partial cross-sectional view of an embodiment of the physiological sign detection device 100 shown in FIG. 2 at K-K during use.

[0607] As shown in FIG. 42, before the physiological sign detection device 100 is used, the fixed table 39 of the support 3 can be located on the side of the seventh elastic arm 58 of the base 5 close to the first elastic member 2.

[0608] As shown in FIGS. 42 and 43, when the first elastic member 2 pushes the support 3 to move downward, the clamping hook of the seventh elastic arm 58 cooperates with the inclined side of the fixed table 391, the fixed table 391 pushes the seventh elastic arm 58, and the clamping hook of the seventh elastic arm 58 opens outward.

[0609] As shown in FIGS. 43 and 44a, when the support 3 reaches the end of the pushing position, the sensor assembly 20 abuts against the living body, at this time, the adhesive member 28 of the sensor assembly 20 contacts the skin of the user, and the clamping hook of the seventh elastic arm 58 clamps the fixed table 391. Exemplarily, in the axial (Z-axis) direction, the clamping hook of the seventh elastic arm 58 is located on the side of the fixed table 391 away from the abutting end 502 of the base 5. In this way, the clamping hook of the seventh elastic arm 58 can limit the support 3 in the axial direction, avoiding the sliding of the support 3 in the axial direction. Meanwhile, the seventh elastic arm 58 is multiple, and the multiple seventh elastic arms 58 are arranged at intervals around the axial direction. The number of the seventh elastic arms 58 is the same as the number of the fixed tables 391, and they are arranged one by one. Two seventh elastic arms 58 and fixed tables 391 are illustrated in this embodiment. The multiple seventh elastic arms 58 cooperate to limit the support 3 in the horizontal direction, preventing the support 3 from shaking after interacting with the skin, keeping the relative position of the support 3 and the skin fixed, reducing the shaking of the support 3 relative to the skin, and reducing the damage to the wound.

[0610] It can be understood that the seventh elastic arm 58 and the fixed table 391 constitute a locking mechanism to prevent the push mechanism from returning, which can effectively reduce the risk of sliding of the support 3 and reduce the damage to the wound.

[0611] FIG. 44b is a partial cross-sectional view of another embodiment of the physiological sign detection device 100 shown in FIG. 2 at K-K.

[0612] As shown in FIGS. 44a and 44b, the seventh elastic arm 58 can also be fixed to one end of the upper side wall 51 of the base 5 away from the abutting end 502. The end of the seventh elastic arm 58 refers to the end of the seventh elastic arm 58 close to the abutting end 502. The hook of the seventh elastic arm 58 is located on the inner side of the base 5 and faces away from the abutting end 502. When the sensor assembly 20 abuts against the living body, in the axial (Z-axis) direction, the hook of the seventh elastic arm 58 is connected to one side of the fixed table 391 close to the abutting end 502 of the base 5.

[0613] It can be understood that the orientation of the hook of the seventh elastic arm 58 can be changed, and when the orientation of the hook of the seventh elastic arm 58 is changed, the connecting surface of the hook of the seventh elastic arm 58 and the fixed table 391 also changes correspondingly.

[0614] In the foregoing embodiments, the first elastic member 2, the spring seat 7, and the support 3 can constitute a push mechanism of the physiological sign detection device 100. The lower housing 1, the base 5, and the support 3 can constitute a trigger mechanism of the physiological sign detection device 100. The needle seat 4, the second elastic member 6, the support 3, the needle seat 22, and the puncture needle 23 can constitute a needle extraction mechanism of the physiological sign detection device 100. The trigger mechanism can serve as a switch for use of the physiological sign detection device 100 to control whether to emit the sensor 24. The push mechanism can be used to push the sensor assembly 20, and the puncture needle 23 can bring the sensor 24 into the tissue of the human body.

[0615] It can be understood that the foregoing specifically introduces an embodiment (the first stop structure 18 and the second stop structure 816) of the anti-falling trigger through the combination of the drawings. By setting the anti-mis-triggering limiting lock (the blocking member 91), the problem of mis-triggering of the device in scenarios such as falling, transportation, and vibration can be completely eliminated. Because the trigger device of the trigger mechanism needs to move axially for a certain stroke to complete the triggering, the axial movement stroke of the device of the trigger mechanism can be limited by the limiting features cooperating with each other, so that the limited axial stroke is smaller than the triggering stroke, to achieve the purpose of preventing mis-triggering. In use, the anti-mis-triggering limiting lock can be automatically or manually released, and after the release, the sensor assembly 20 can smoothly complete the triggering.

[0616] The limiting lock can be a limiting feature of the trigger device, a limiting feature of a limiting device or a limiting module.

[0617] Exemplarily, the limiting device can be separate or can have the function of limiting other parts.

[0618] Exemplarily, the interlocking limiting feature can be a single or multi-threaded screw, a smooth buckle, an inclined sliding buckle, a spiral sliding buckle, or a snap ring.

[0619] Exemplarily, the limiting lock can be automatically released by removing other parts, such as unscrewing the bottle cap, and the limiting lock is automatically released. If a special unlocking action is required, such as removing the snap ring, or manually rotating or pressing the limiting device to unlock, the limiting lock is manually released.

[0620] In the following, several limiting locks (blocking structures) will be described in detail with reference to the accompanying drawings.

[0621] In some embodiments, the same parts as described in the previous embodiments will not be described again.

[0622] FIG. 45 is a schematic view of another embodiment of the physiological sign detection device 100 shown in FIG. 2. FIG. 46 is an exploded schematic view of an embodiment of the physiological sign detection device 100 shown in FIG. 45.

[0623] As shown in FIGS. 45 and 46, the physiological sign detection device 100 can include the implant device 10 and the sensor assembly 20. The implant device 10 can include the lower housing 1, the first elastic member 2, the spring seat 7, the base 5, the needle seat 4, the second elastic member 6, the bracket 3, the blocking piece 91, the first magnet 9, and the cap assembly 8. The first elastic member 2, the spring seat 7, the needle seat 4, the second elastic member 6, the bracket 3, the first magnet 9, and the cap assembly 8 can be arranged in the same manner as described in the previous embodiments, and will not be described again here.

[0624] FIG. 47 is a structural schematic view of an embodiment of the lower housing 1 shown in FIG. 46.

[0625] As shown in FIG. 47, the lower housing 1 can further include the first limiting block 19. The first limiting block 19 is fixedly connected to the inner side of the side wall 11 of the lower housing 1 and exposed to the opening 101 of the lower housing 1. The number of the first limiting block 19 can be one or more. When the number of the first limiting block 19 is more than one, the plurality of first limiting blocks 19 are arranged at intervals around the central axis of the lower housing 1.

[0626] FIG. 48 is a structural schematic view of an embodiment of the base 5 shown in FIG. 46.

[0627] As shown in FIG. 48, the base 5 further comprises a second limiting block 5083 fixed to the outer side of the abutting end 502. Exemplarily, the second limiting block 5083 can be a skirt.

[0628] FIG. 49 is a structural schematic diagram of an embodiment of the blocking piece 91 shown in FIG. 46.

[0629] As shown in FIG. 49, the blocking piece 91 can be a half-ring structure. The blocking piece 91 can have an opening 9101. In this way, after the user removes the shell cap assembly 8 when using the physiological sign detection device 100, the user can remove the blocking piece 91, unlock, and trigger the mechanism to work normally.

[0630] Exemplarily, the outer side of the blocking piece 91 can be provided with anti-skid lines 911. In this way, the user can easily hold the blocking piece 91.

[0631] FIG. 50 is an assembly schematic diagram of an embodiment of the base 5 and the lower shell 1 shown in FIG. 46.

[0632] As shown in FIG. 50, when the base 5 is installed on the lower shell 1, the axial direction of the base 5 can coincide with the axial direction of the lower shell 1. The second limiting block 5083 of the base 5 extends out of the shell, and the first limiting block 19 and the second limiting block 5083 can be oppositely arranged in the axial direction of the physiological sign detection device 100.

[0633] FIG. 51 is an assembly schematic diagram of an embodiment of the snap ring, the base 5, and the lower shell 1 shown in FIG. 46. FIG. 52 is a cross-sectional schematic diagram of an embodiment of the physiological sign detection device 100 shown in FIG. 45 at A2-A2.

[0634] As shown in FIG. 51 and FIG. 52, the blocking piece 91 is detachably connected to the base 5. In the axial direction of the physiological sign detection device 100, the blocking piece 91 is arranged between the first limiting block 19 of the lower shell 1 and the second limiting block 5083 of the base 5. When the physiological sign detection device 100 is impacted, the blocking piece 91 can abut between the first limiting block 19 and the second limiting block 5083, the blocking piece 91 can limit the relative movement tendency between the base 5 and the lower shell in the axial direction, and block the movement of the base 5 relative to the lower shell 1 in the axial direction of the physiological sign detection device 100, that is, the axial movement stroke of the base 5 towards the triggering direction is limited. In this way, the push block 15 of the lower shell cannot expand the second elastic arm 56 of the base 5, and the bracket 3 can be prevented from being triggered by mistake.

[0635] When the physiological sign detection device 100 switches from the non-use state to the use state, the upper shell 81 is detached from the lower shell 1, the blocking piece 91 is detached from the base 5, the abutting end 502 can abut the biological body, the user can exert a force on the lower shell 1 towards the biological body, and the bracket 3 is triggered.

[0636] In some embodiments, the blocking piece 91 can be a semi-ring structure. The central angle of the semi-ring structure is greater than 180°. In this way, the blocking piece 91 can be clamped to the base 5 by its own structure, and it can not be necessary to additionally provide a fixed structural member.

[0637] In other embodiments, the blocking piece 91 can also be a plate structure or the like other than the semi-ring structure.

[0638] In some embodiments, the same parts as in the previous embodiments will not be described here.

[0639] FIG. 53 is a schematic view of another embodiment of the physiological sign detection device 100 shown in FIG. 2. FIG. 54 is an exploded schematic view of an embodiment of the physiological sign detection device 100 shown in FIG. 53.

[0640] As shown in FIGS. 53 and 54, the physiological sign detection device 100 can include the implant device 10 and the sensor assembly 20. The implant device 10 can include the lower shell 1, the first elastic member 2, the spring seat 7, the base 5, the needle seat 4, the second elastic member 6, the bracket 3, the first magnet 9, and the cap assembly 8. Among them, the setting mode of the lower shell 1, the first elastic member 2, the spring seat 7, the needle seat 4, the second elastic member 6, the bracket 3, and the first magnet 9 can refer to the setting mode of the lower shell 1, the first elastic member 2, the spring seat 7, the needle seat 4, the second elastic member 6, the bracket 3, and the first magnet 9 described in the previous embodiments, which will not be described here. The cap assembly 8 can include the upper shell 81, the desiccant 82, and the second magnet 83. The setting mode of the desiccant 82 and the second magnet 83 can refer to the setting mode of the desiccant 82 and the second magnet 83 described in the previous embodiments.

[0641] FIG. 55 is a structural schematic view of an embodiment of the upper shell 81 shown in FIG. 54.

[0642] As shown in FIG. 55, the blocking piece 91 (limiting short rib) can be fixedly connected to the inner side of the side wall 812 of the upper shell 81. For example, the blocking piece 91 can be located on the side of the upper shell 81 close to the bottom wall 811 of the threaded engagement, and is arranged in a spaced manner with the threaded engagement of the upper shell 81.

[0643] In some embodiments, the number of the blocking members 91 can be one or more. For example, the blocking members 91 can be a continuous thread or several segments within a thread. When the number of the blocking members 91 is more than one, the blocking members 91 can be spaced apart and arranged uniformly around the axial direction of the physiological sign detection device 100.

[0644] It can be understood that when the blocking members 91 are threads, the pitch of the threads of the blocking members 91 is the same as the pitch of the engagement threads of the upper shell 81.

[0645] FIG. 56 is a structural schematic diagram of an embodiment of the base 5 shown in FIG. 54. FIG. 57 is a sectional schematic diagram of an embodiment of the physiological sign detection device 100 at A3-A3 shown in FIG. 53.

[0646] As shown in FIGS. 56 and 57, the lower side wall 52 of the base 5 (e.g., the abutting end 502) is exposed to the lower shell 1. The lower side wall 52 of the base 5 can be provided with a limiting groove 521. For example, the abutting end 502 can be provided with the limiting groove 521.

[0647] In some embodiments, the limiting groove 521 can be a threaded groove. The pitch of the limiting groove 521 can be the same as the pitch of the blocking members. In this way, the blocking members 91 can better cooperate with the limiting groove 521. The blocking members 91 can also be longer in the axial direction of the upper shell 81. The contact area between the blocking members 91 and the base 5 can be larger, which can better block the movement of the base relative to the lower shell in the axial direction of the physiological sign detection device.

[0648] In some embodiments, the number of the blocking members 91 is more than one. It can be understood that compared with the case where the number of the blocking members is one, the number of the blocking members is set to be more, which is beneficial to increase the contact area between the blocking members 91 and the base 5, and can better block the movement of the base relative to the lower shell in the axial direction of the physiological sign detection device.

[0649] In some embodiments, the limiting groove 521 is a threaded groove, and the pitch of the threaded groove can be the same as the pitch of the engagement threads of the upper shell 81.

[0650] It can be understood that when the upper shell 81 is mounted on the lower shell 1, the blocking piece 91 is partially located in the limiting groove 521. For example, when the upper shell 81 and the lower shell 1 are tightened by engaging threads, the blocking piece 91 can slide into the threaded limiting groove 521 of the lower side wall 52 of the base 5. The blocking piece 91 and the base 5 are oppositely arranged in a direction parallel to the axial direction (Z-axis) of the physiological sign detection device 100. When the physiological sign detection device 100 is impacted, the blocking piece 91 can limit the relative movement trend between the base 5 and the upper shell 81 in the axial direction, and the lower shell 1 is fixed on the upper shell 81. Therefore, the blocking piece 91 can limit the relative movement trend between the base 5 and the lower shell 1 in the axial direction, and block the movement of the base 5 relative to the lower shell 1 in the axial direction of the physiological sign detection device 100, that is, the axial movement stroke of the base 5 towards the triggering direction is limited. In this way, the abutting block 15 of the lower shell 1 cannot expand the second elastic arm 56 of the base 5 (in combination with FIG. 39), so as to avoid the bracket 3 from being triggered by mistake.

[0651] In the following, another anti-shock design will be introduced in combination with the drawings. In some embodiments, the same parts as those in the foregoing embodiments will not be described herein again. FIG. 58 is a structural schematic view of another embodiment of the bracket 3 shown in FIG. 3.

[0652] As shown in FIG. 58, the bracket 3 can have a flange 34. The flange 34 of the bracket 3 can be protruded from the outer side of the bracket 3.

[0653] FIG. 59 is a structural schematic view of another embodiment of the base 5 shown in FIG. 3.

[0654] As shown in FIG. 59, the base 5 can also be provided with an elastic locking buckle 591. One end of the elastic locking buckle 591, which is towards the upper side wall 51 of the base 5, is fixedly connected to the lower side wall 52 of the base 5, and the other end is spaced apart from the lower side wall 52 of the base 5. The other end of the elastic locking buckle 591, which is away from the top wall 12 of the lower shell 1, is spaced apart from the abutting end 502, and the elastic locking buckle 591 protrudes from the inner side of the base 5. For example, the other end of the elastic locking buckle 591 partially protrudes into the space surrounded by the lower side wall 52 of the base 5.

[0655] For example, the number of the elastic locking buckles 591 can be multiple, and the multiple elastic locking buckles 591 can be spaced apart in the axial direction of the base 5. For example, the number of the elastic locking buckles 591 is three, and the three elastic locking buckles 591 are spaced apart.

[0656] FIG. 60 is a partial cross-sectional view of another embodiment of the physiological sign detection device 100 shown in FIG. 2 at F-F. FIG. 61 is a partial cross-sectional view of an embodiment of the physiological sign detection device 100 shown in FIG. 2 at F-F during use. FIG. 62 is a partial cross-sectional view of an embodiment of the physiological sign detection device 100 shown in FIG. 2 at F-F during use.

[0657] As shown in FIGS. 60-62, when the physiological sign detection device 100 is switched from the non-use state to the use state, when the upper housing 81 is detached from the lower housing 1, when the bracket 3 moves toward the biological body (in the opposite direction of the Z-axis), and when the sensor assembly 20 abuts against the biological body, the elastic locking catch 591 abuts against one side of the flange 34 of the bracket 3 that is close to the top wall 12 of the lower housing 1. For example, the elastic locking catch 591 abuts against one side of the flange 34 of the bracket 3 that is close to the top wall 12 of the lower housing 1.

[0658] For example, when the bracket 3 is unlocked, during the downward movement under the action of the first elastic member 2, the flange 34 of the bracket 3 can push apart the elastic locking catch 591 until the bracket 3 pushes the adhesive member 28 of the sensor assembly 20 into place, that is, the adhesive member 28 is substantially flush with the abutting end 502 of the base 5, the elastic locking catch 591 rebounds, and abuts against one side of the flange 34 of the bracket 3 that is close to the top wall 12 of the lower housing 1 to limit the axial movement of the bracket 3 and prevent the bracket 3 from sliding in the axial direction. Multiple elastic locking catches 591 surround the bracket 3 and abut against the bracket 3 in the axial direction to limit the bracket 3 in the horizontal direction, prevent the bracket 3 from shaking after interacting with the skin, keep the relative position of the bracket 3 and the skin fixed, reduce the shaking of the bracket 3 relative to the skin, and reduce the damage to the wound.

[0659] The foregoing embodiments introduce a double-headed ratchet that allows the sealing bottle 29 to be loosened when the cap assembly 8 is removed. However, the double-headed ratchet has no tolerance capability when the relative position of the upper housing 81 and the sealing bottle 29 is abnormal (for example, installation error), and the upper housing 81 needs to be turned an additional double stroke to loosen the sealing bottle 29. When the loosening stroke of the upper housing 81 is not enough, it cannot be guaranteed that the sealing bottle 29 will be separated from the guide needle when the cap assembly 8 is removed. The following will introduce several ratchet structures with certain tolerance capability in combination with the accompanying drawings.

[0660] In some embodiments, the same parts as those described in the foregoing embodiments will not be described again here. FIG. 63 is an exploded view of another embodiment of the cap assembly 8 shown in FIG. 3. FIG. 64a is an assembly view of an embodiment of the unlocking ratchet 817, the upper housing 81, and the sealing bottle 29 shown in FIG. 63.

[0661] As shown in FIG. 63 and FIG. 64a, the cap assembly 8 can include an upper shell 81, a desiccant 82 and a second magnet 83. The upper shell 81 can include a bottom wall 811, a side wall 812 and an unlocking ratchet 817. The side wall 812 of the upper shell 81 is connected to the periphery of the bottom wall 811 of the upper shell 81. The assembly of the upper shell 81, the desiccant 82 and the second magnet 83 can refer to the assembly of the previous embodiments, which will not be described here.

[0662] FIG. 64b is a structural schematic diagram of an embodiment of the unlocking ratchet 817 shown in FIG. 63. FIG. 65a is a structural schematic diagram of another embodiment of the sealed bottle 29 shown in FIG. 64a.

[0663] As shown in FIG. 64a to FIG. 65a, the unlocking ratchet 817 is fixedly connected to the bottom wall 811 of the upper shell 81. The inner wall surface of the unlocking ratchet 817 is provided with a plurality of ratchet inclined teeth 8171. The outer side surface of the sealed bottle 29 can be provided with elastic arms 294. The elastic arms 294 can be used to cooperate with the ratchet inclined teeth 8171 of the unlocking ratchet 817 to achieve the disassembly of the sealed bottle 29 and the needle seat 22. Exemplarily, during the screwing of the upper shell 81 relative to the lower shell 1, the elastic arms 294 can be slidingly connected to the unlocking ratchet 817. During the disengagement of the upper shell 81 from the lower shell 1, the elastic arms 294 can be clamped to the unlocking ratchet 817 and push the sealed bottle 29 away from the needle seat 22.

[0664] Exemplarily, the mouth of the unlocking ratchet 817 can be provided as an inverted buckle, so that the ratchet 293 and the elastic arm 294 can be mutually inverted in the length direction of the sealed bottle 29. After the unlocking of the sealed bottle 29 and the needle seat 22, the upper shell 81 can hook the sealed bottle 29, so that the sealed bottle 29 can be taken off with the lower shell 1.

[0665] Exemplarily, the number of the ratchet inclined teeth 8171 is a plurality. Exemplarily, the number of the ratchet inclined teeth 8171 in the drawings of the embodiment is n = 12.

[0666] In some embodiments, the number of the elastic arms 294 on the outer side surface of the sealed bottle 29 can be a plurality of groups. The plurality of groups of elastic arms 294 can be located at one height or at different heights. In the drawings of the embodiment, the different groups of elastic arms 294 are located at different heights.

[0667] Exemplarily, the number of a group of elastic arms 294 is a plurality. In the drawings, the number of a group of elastic arms is three.

[0668] Exemplarily, the sealing bottle 29 comprises a plurality of first elastic arms 2941 protruding from the outer side of the sealing bottle 29. The plurality of first elastic arms 2941 constitute a first elastic arm group. The sealing bottle 29 further comprises a plurality of second elastic arms 2942 protruding from the outer side of the sealing bottle 29, and the ratchet wheel 293 and the plurality of second elastic arms 2942 are arranged in cooperation. The plurality of second elastic arms 2942 constitute a second elastic arm group. The first elastic arm group and the second elastic arm group are arranged staggered in the axial direction of the physiological sign detection device 100.

[0669] It can be understood that the rotation angles of the elastic arms 294 in different groups are different, and the two groups of elastic arms 294 have a rotation angle a. That is, any one group of elastic arms in the two groups of elastic arms is rotated by an angle a relative to the other group of elastic arms, and the two groups of elastic arms 294 coincide in the axial direction. For example, when the sealing bottle 29 is installed in the unlocking ratchet wheel 817, the end surface of the first group of elastic arms 294 can be engaged with the short side of the ratchet tooth 8171, and the end surface of the second group of elastic arms 294 is arranged in a spaced manner with the short side of the ratchet tooth 8171. At this time, the sealing bottle 29 needs to be rotated by an angle a1 relative to the unlocking ratchet wheel 817 to realize the engagement of the end surface of the second group of elastic arms 294 with the short side of the ratchet tooth 8171. a can be equal to Cx(360° / n)+a1, C is a non-zero integer. a1 can be greater than 0° and less than (360° / n). Exemplarily, a1=(360° / 2n), when n=12, a can be (Cx30°+15°), and a1 can be (360° / 24)=15°. In this way, the second group of elastic arms only needs to be rotated by 15° to realize the engagement with the short side of the ratchet tooth 8171 compared with the forward rotation or reverse rotation of the unlocking ratchet wheel 817.

[0670] It can be understood that, compared with when the pawl is on the upper shell, the pawl position needs to be strongly removed when the upper shell is molded, and the pawl is easy to expand and deform; or the pawl and the upper shell are separately prepared, and the assembly process is complex and the cost is high. The elastic arm 294 is placed on the outer side of the sealing bottle 29, and the position of the elastic arm 294 is on the outer surface, so that strong removal is not required.

[0671] FIG. 65b is a partial cross-sectional view of an embodiment of the structure shown in FIG. 64a at A4-A4.

[0672] As shown in FIG. 65b, when the sealing bottle 29 is installed in the unlocking ratchet wheel 817, the end surface of the elastic arm 294 can be engaged with the short side of the ratchet tooth 8171, and the cap assembly 8 is removed, and the short side of the ratchet tooth abuts against the end surface of the elastic arm 294, thereby driving the sealing bottle 29 to rotate, so that the sealing bottle 29 can also be loosened, and the cap assembly 8 is removed.

[0673] For example, if there is an error in the installation position of the sealing bottle 29 and the unlocking ratchet 817, that is, the sealing bottle 29 and the unlocking ratchet 817 are relatively arranged with an angle deflection, if there is only one set of elastic arms 294, it needs to be rotated by an angle of (360° / n) to make the end surface of the elastic arm 294 correctly mesh with the short side of the ratchet oblique tooth 8171, and when there are two sets of elastic arms 294, it only needs to be rotated by an angle of (360° / 2n), and one set of elastic arms between the two sets of elastic arms 294 can correctly mesh with the short side of the ratchet oblique tooth 8171. It can be understood that the number of sets of elastic arms 294 can also be more than two, so that when the installation position of the sealing bottle 29 and the unlocking ratchet 817 has an angle deflection, the upper shell 81 only needs to be rotated by a smaller angle to achieve correct meshing of the elastic arm 294 and the short side of the ratchet oblique tooth 8171.

[0674] It can be understood that in the present embodiment, by setting multiple sets of elastic arms 294 and unlocking ratchets 817, the tolerance capability can be achieved, and when the upper shell 81 and the sealing bottle 29 are assembled with an angle deflection, only a smaller angle needs to be rotated to achieve correct meshing of the elastic arm 294 and the ratchet 293, avoiding the situation that the sealing bottle 29 cannot be taken off with the shell cap assembly 8 because the locking thread between the sealing bottle 29 and the guide needle has not been completed even though the engagement thread of the upper shell 81 has been completed.

[0675] It can be understood that in the present embodiment, the elastic arms 294 are arranged on the outer side of the sealing bottle 29, and the unlocking ratchet 817 is arranged on the upper shell 81. In other embodiments, the positions of the elastic arms 294 and the unlocking ratchet 817 can also be interchanged.

[0676] In some embodiments, the same parts as in the previous embodiments will not be described again. FIG. 66a is a structural schematic diagram of another embodiment of the sealing bottle 29 shown in FIG. 64a. FIG. 66b is a partial cross-sectional view of another embodiment of the structure shown in FIG. 64a at A4-A4.

[0677] As shown in FIGS. 66a and 66b, in the present embodiment, the difference from the previous embodiment is that the multiple sets of elastic arms 294 included in the sealing bottle 29 are at the same height.

[0678] For example, the sealing bottle 29 includes two sets of elastic arms 294, which are a first set of elastic arms and a second set of elastic arms. The number of elastic arms in each set is two. The multiple elastic arms 294 of the two sets can be arranged at intervals around the axis of the sealing bottle 29. Any one elastic arm 294 of one set is located between the two elastic arms 294 of the other set. For example, any one first elastic arm 2941 can be located between the two second elastic arms 2942.

[0679] Exemplarily, the rotation angles of the elastic arms 294 in different groups are different, and the rotation angle a exists between the elastic arms 294 in two groups. For example, when the sealing bottle 29 is installed on the unlocking ratchet 817, the end surface of the elastic arms 294 in the first group can engage with the short side of the ratchet oblique tooth 8171, and the end surface of the elastic arms 294 in the second group is spaced apart from the short side of the ratchet oblique tooth 8171 and does not engage. Assuming that when the sealing bottle 29 is rotated by an angle a1 relative to the unlocking ratchet 817 again, the end surface of the elastic arms 294 in the second group can also engage with the short side of the oblique tooth. a can be equal to 90°+a1, or 90°-a1, and C is a non-zero integer. a1 can be greater than 0° and less than (360° / n). Exemplarily, a1=(360° / 2n), when n=12, a can be (C×30°+15°), and a1 can be (360° / 24)=15°. In this way, when the installation between the sealing bottle 29 and the upper shell 81 exists an error and does not correctly engage, the sealing bottle 29 needs to be rotated by a maximum of 15° in the forward direction or in the reverse direction relative to the unlocking ratchet 817 to achieve the engagement with the short side of the ratchet oblique tooth 8171.

[0680] In some embodiments, the same parts as in the previous embodiments are not described again here. FIG. 67a is a structural schematic diagram of still another embodiment of the physiological sign detection device 100 shown in FIG. 2. FIG. 67b is a partial structural schematic diagram of an embodiment of the shell cap assembly 8 shown in FIG. 67a. FIG. 67c is a structural schematic diagram of an embodiment of the shell cap assembly 8 shown in FIG. 67b.

[0681] As shown in FIG. 67a and FIG. 67b, the shell cap assembly 8 can include the upper shell 81, the desiccant 82, the decorative piece 84, and the sealing piece 85.

FIG. 68b is a partial structural schematic diagram of an embodiment of the upper shell 81 shown in FIG. 68a from another angle.

[0683] As shown in FIG. 67c to FIG. 68b, the upper shell 81 can include the bottom wall 811, the side wall 812, the clamping arm assembly 818, and the clamping boss 819. Among them, the side wall 812 of the upper shell 81 is circumferentially connected to the periphery of the bottom wall 811 of the upper shell 81. The clamping boss 819 is fixedly connected to the side of the bottom wall 811 of the upper shell 81 facing the top wall 12 of the lower shell 1, and the clamping boss 819 is provided with a clamping groove 8191. The opening of the clamping groove 8191 can be towards the top wall 12 of the lower shell 1 (away from the bottom wall 811 of the upper shell).

[0684] In some embodiments, the side of the bottom wall 811 of the upper shell 81 away from the side wall 11 can be provided with a positioning groove.

[0685] FIG. 68c is a structural diagram of an embodiment of the clamping arm assembly 818 shown in FIG. 67c.

[0686] As shown in FIG. 68c, the clamping arm assembly 818 can include a clamping arm 8181, a bottom plate 8182, a positioning rod 8183, and a clamping claw 8184. The clamping arm 8181, the positioning rod 8183, and the clamping claw 8184 can be fixedly connected to the same side of the bottom plate 8182 of the clamping arm assembly 818. One end of the clamping arm 8181 can be fixedly connected to the bottom plate 8182 of the clamping arm assembly 818, and the other end can be provided with a clamping hook. One end of the clamping claw 8184 can be fixedly connected to the bottom plate 8182 of the clamping arm assembly 818, and the other end can be provided with a clamping hook.

[0687] Exemplarily, the number of clamping arms 8181 can be one or multiple. Exemplarily, the number of clamping arms 8181 can be multiple, and the multiple clamping arms 8181 can be arranged around the central axis of the physiological sign detection device 100. Two clamping arms 8181 are shown in the figure.

[0688] Exemplarily, the number of clamping claws 8184 can be one or multiple. Exemplarily, the number of clamping claws 8184 can be multiple, and the multiple clamping claws 8184 can be arranged around the central axis of the physiological sign detection device 100. Four clamping claws 8184 are shown in the figure.

[0689] In some embodiments, the positioning rod 8183 can be fixedly connected between the two clamping arms 8181.

[0690] FIG. 68d is an assembly diagram of an embodiment of the clamping arm assembly 818 and the upper shell 81 shown in FIG. 67b.

[0691] As shown in FIGS. 67d and 68d, the clamping arm assembly 818 can be detachably fixedly connected to the upper shell 81. Exemplarily, the bottom wall 811 of the upper shell 81 is provided with a mounting hole 8112 (as shown in FIG. 68b), and the mounting hole 8112 penetrates the bottom wall 811 of the upper shell 81. The bottom plate 8182 of the clamping arm assembly 818 can be located on the side of the bottom wall 811 of the upper shell 81 away from the side wall 812 of the upper shell 81. One end of the clamping arm 8181 can be detachably fixedly connected to the bottom wall 811 of the upper shell 81, and the other end can extend into the side of the bottom wall 811 of the upper shell 81 facing the top wall 12 of the lower shell 1 through the mounting hole 8112. Exemplarily, one end of the clamping arm 8181 is fixedly connected to the bottom plate 8182 of the clamping arm assembly 818.

[0692] In some embodiments, the clamping claw 8184 of the clamping arm assembly 818 can be clamped to the bottom wall 811 of the upper shell 81.

[0693] FIG. 68e is a schematic view of another embodiment of the sealed bottle 29.

[0694] As shown in FIG. 68e, the sealed bottle 29 has a limiting groove 295, and the opening of the limiting groove 295 can be located on the side of the sealed bottle 29. The groove wall of the limiting groove 295 comprises a first limiting surface 2951 and a second limiting surface 2952, and the first limiting surface 2951 and the second limiting surface 2952 can be spaced apart along the circumference of the sealed bottle 29.

[0695] In some embodiments, the groove wall of the limiting groove 295 can further comprise a third limiting surface 2953, and the third limiting surface 2953 is connected between the first limiting surface 2951 and the second limiting surface 2952.

[0696] In some embodiments, the number of the limiting grooves 295 can be one or multiple. When the number of the limiting grooves 295 is multiple, the multiple limiting grooves 295 are spaced apart along the circumference of the sealed bottle 29. For example, the number of the limiting grooves 295 is two, and the two limiting grooves 295 are symmetric about the central axis of the sealed bottle 29.

[0697] FIG. 69a is a partial cross-sectional view of one embodiment of the physiological sign detection device 100 at C4-C4. The assembly of one embodiment of the sealed bottle 29 and the shell cap assembly 8 is shown in FIG. 69a.

[0698] As shown in FIG. 69a, when the physiological sign detection device 100 is in the unused state, the end of the sealed bottle 29 away from the needle seat 22 abuts within the clamping groove 8191. The clamping arm 8181 can detachably connect the sealed bottle 29. For example, the clamping hook of the clamping arm 8181 faces the sealing member 85, and is located at the end of the clamping arm 8181 away from the bottom wall 811 of the upper shell 81. The clamping hook of the clamping arm 8181 is at least partially located within the limiting groove 295. Along the circumference of the sealed bottle 29, the clamping hook of the clamping arm 8181 can be located between the first limiting surface 2951 and the second limiting surface 2952.

[0699] In some embodiments, the number of the clamping arms 8181 can be multiple, and the number of the limiting grooves 295 can also be multiple. The number of the clamping arms 8181 is equal to the number of the limiting grooves 295. The multiple clamping arms 8181 and the multiple limiting grooves 295 are arranged in one-to-one correspondence.

[0700] FIG. 69b is a partial cross-sectional view of one embodiment of the physiological sign detection device 100 at D4-D4 during assembly. FIG. 69c is a partial cross-sectional view of one embodiment of the physiological sign detection device 100 at D4-D4 during assembly. FIG. 69d is a partial cross-sectional view of one embodiment of the physiological sign detection device 100 at D4-D4 during assembly. FIG. 69e is a partial cross-sectional view of one embodiment of the physiological sign detection device 100 at D4-D4 during assembly.

[0701] The assembly process of the shell cap assembly 8 is illustrated in FIGS. 69b-69e. The clip arm assembly 818 of the upper shell 81 can be assembled after the other components of the physiological sign detection device 100 are assembled. It can be appreciated that, compared to the previous embodiments, the clip arm 8181 is assembled as a separate detachable structure in this embodiment, and the sealing bottle 29 is assembled first, which can avoid the sealing bottle 29 from being damaged when the clip arm 8181 is assembled.

[0702] As shown in FIGS. 69b and 69c, the end of the side wall 812 of the upper shell 81 away from the bottom wall 811 of the upper shell 81 detachably fixes the lower shell 1. The clip arm assembly 818 can enter the physiological sign detection device 100 through the mounting hole 8112 of the bottom wall 811 of the upper shell 81. The side of the clamping boss 819 away from the bottom wall 811 of the upper shell 81 can protrude toward the side wall 812 of the upper shell 81 to form a guide slope 8191. The guide slope 8191 can be arranged at an angle to the axial direction of the upper shell 81. The clip arm 8181 can cooperate with the guide slope 8191, and the plurality of clip arms 8181 can be spread apart by the clamping boss 819.

[0703] In some embodiments, the guide slope 8191 can include a first slope 8192 and a second slope 8193, the first slope 8192 facing the bottom wall 811 of the upper shell 81, and the second slope 8193 facing away from the bottom wall 811 of the upper shell 81. During the process of the clip arm assembly 818 approaching the sealing bottle 29, the clip arm 8181 is first spread apart and then gradually gathered under the action of the guide slope 8191.

[0704] Figure 69d illustrates the mounting relationship between the clamping jaw 8184 of the clamping arm assembly 818 and the bottom wall 811 of the upper shell 81. During the mounting process of the clamping arm assembly 818, the clamping jaw 8184 can first be abutted by the wall of the mounting hole 8112, and the end of the clamping jaw 8184 away from the bottom plate 32 of the clamping arm assembly 818 is moved towards the central axis of the clamping arm 8181. After the clamping hook of the clamping jaw 8184 enters the side of the bottom wall 811 of the upper shell 81 close to the side wall 812 of the upper shell 81, the clamping jaw 8184 is disengaged from the abutting relationship with the hole wall of the mounting hole 8112, and the clamping jaw 8184 returns to its original shape and is clamped to the bottom wall 811 of the upper shell 81.

[0705] In some embodiments, as shown in Figure 69e, the third limiting surface 2953 and the clamping hook of the clamping arm 8181 are oppositely arranged in a direction parallel to the axial direction of the sealing bottle 29. In this way, when the physiological sign detection device 100 is switched from the non-use state to the use state, the clamping arm 8181 can clamp the sealing bottle 29 through the third limiting surface 2953 and push the sealing bottle 29 away from the needle seat 22 during the process of separating the upper shell 81 from the lower shell 1.

[0706] In some embodiments, the outer diameter of the clamping protrusion 819 is greater than the outer diameter of the sealing bottle 29. In this way, the clamping arm assembly 818 is less likely to bump into the sealing bottle 29 during the mounting process, reducing the risk of damage to the sealing bottle 29 and avoiding the situation that the sealing bottle 29 cannot be removed together with the upper shell 81 when the upper shell 81 is separated from the lower shell 1.

[0707] In some embodiments, after the clamping arm assembly 818 is mounted, there is a gap between the clamping arm 8181 and the sealing bottle 29 in the radial direction of the sealing bottle 29. It can be understood that this gap can be reserved for the rotation formed when the upper shell 81 is separated from the lower shell 1.

[0708] It can be understood that in the present embodiment, along the circumferential direction of the sealing bottle 29, the limiting groove 295 of the side surface of the sealing bottle 29 has two limiting surfaces (the first limiting surface 2951 and the second limiting surface 2952). During the process of separating the upper shell 81 from the lower shell 1, the upper shell 81 rotates the sealing bottle 29, the contact surface between the clamping arm 8181 and the sealing bottle 29 is larger, the clamping hook of the clamping arm 8181 is limited by the limiting surfaces on both sides, and the sealing bottle 29 is less likely to be separated from the upper shell 81, reducing the risk of the sealing bottle 29 falling and damaging the puncture needle 23 and the adhesive member 28 when the sealing bottle 29 is removed.

[0709] In some embodiments, the sealing member 85 can be fixedly connected between the bottom wall 811 of the upper housing 81 and the bottom plate 8182 of the clamping arm assembly 818. The sealing member 85 can be used to seal the gap between the clamping arm assembly 818 and the bottom wall 811 of the upper housing 81, improving the sealing performance of the physiological sign detection device 100. For example, the sealing member 85 can be glue, such as waterproof glue, etc.

[0710] In some embodiments, the decorative member 84 can be fixedly connected to the side of the bottom plate 8182 of the clamping arm assembly 818 away from the lower housing 1. That is, the decorative member 84 can be fixedly connected to the side surface of the shell cap assembly 8 away from the lower housing 1, so that the decorative member 84 can be used to cover the gap between the clamping arm assembly 818 and the upper housing 81, improving the appearance of the physiological sign detection device 100.

[0711] It can be understood that the above embodiments illustrate the use of double-start threads for the fool-proof design between the upper housing 81 and the lower housing 1. Hereinafter, a multi-start thread fool-proof design will be described in detail in combination with the drawings.

[0712] FIG. 70a is a structural schematic view of another embodiment of the lower housing 1 provided by the present application. FIG. 70b is a structural schematic view of the lower housing 1 shown in FIG. 70a from another angle. FIG. 70c is a structural schematic view of the lower housing 1 shown in FIG. 70a from yet another angle.

[0713] As shown in FIGS. 70a to 70c, the engagement threads of the lower housing 1 include three threads with the same pitch and thickness. The starting heights of the different threads are different, and the starting positions are arranged around the axial direction of the lower housing 1. Moreover, the distance between any two adjacent threads is different. In this way, the three threads can form three engagement positions with different sizes. For example, the three threads can form three engagement positions with different sizes, i.e., a thick thread engagement opening 104, a thin thread engagement opening 105, and a medium thread engagement opening 106.

[0714] FIG. 71a is a structural schematic view of another embodiment of the upper housing 81 provided by the present application. FIG. 71b is a structural schematic view of the upper housing 81 shown in FIG. 71a from another angle. FIG. 71c is a structural schematic view of the upper housing 81 shown in FIG. 71a from yet another angle.

[0715] As shown in FIGS. 71a-71c, the inner side of the side wall 812 of the upper shell 81 is provided with three threads of different widths. The three threads of different widths start at different positions on the circumference of the inner side of the side wall 812 of the upper shell 81. When the upper shell 81 and the lower shell 1 are screwed together by the threads, the three threads of different widths of the upper shell 81 correspond to three different sizes of the engagement positions on the lower shell 1. The upper shell 81 can only be screwed in at a specific initial angle with the lower shell 1, so that the three threads can be properly engaged and the upper shell 81 can be tightened. For example, the engagement threads of the upper shell 81 can include a coarse thread 817, a fine thread 818 and a medium thread 819.

[0716] It can be understood that when the upper shell 81 is detachably connected to the lower shell 1, the coarse thread 817 is engaged from the coarse thread engagement opening 104, the fine thread 818 is engaged from the fine thread engagement opening 105, and the medium thread 819 is engaged from the medium thread engagement opening 106.

[0717] For example, the threads of the upper shell 81 can have limiting features 107 that abut against each other, so that after being screwed in place, the upper shell 81 and the lower shell 1 cannot rotate again and the relative position is fixed. Limiting features are also added at the starting position of the threads of the lower shell 1 and the ending position of the threads of the upper shell 81. After the upper shell 81 and the lower shell 1 are tightened, the two limiting features are engaged without clearance, so that the position of the upper shell 81 relative to the lower shell 1 cannot be deviated in the tightening direction again.

[0718] It can be understood that several fool-proof designs of multi-thread are introduced in the embodiments of the present application through the drawings. By providing a multi-thread structure, the different threads have the same thread pitch and different starting heights, so that the reverse installation problem of the upper shell 81 and the lower shell 1 during installation can be avoided. Specifically, the lower shell 1 is designed with multiple threads, the starting heights of one or more threads are designed to be different, forming thread engagement openings of different widths, and the upper shell 81 is provided with multiple threads of different widths. Each width of thread can only be screwed in from the corresponding engagement opening to be screwed in and tightened. If it is screwed in from a different engagement opening, the coarse thread and the fine thread engagement opening will interfere and cannot be tightened.

[0719] In addition, the limiting function can make the relative position of the upper shell 81 and the lower shell 1 after being tightened be unique, so as to meet the structural design that needs a specific position. For example, the upper shell 81 has a magnet for sensing the on-off of a switch, and the magnet needs to be assembled at a fixed position.

[0720] For example, the number of threads of the multi-thread can be double, triple, quadruple, etc.

[0721] For example, the cross section of the thread can be trapezoidal, triangular or parallelogram-shaped.

[0722] Exemplarily, the limiting feature can be a planar fit, or a spherical or arc surface fit.

[0723] It can be understood that in the foregoing embodiments, the base 5, the needle extraction seat 4, the second elastic member 6, the support 3, the needle seat 22, and the puncture needle 23 can constitute a needle extraction mechanism of the physiological sign detection device 100. The needle extraction mechanism is used to realize the function of pushing the puncture needle 23 to penetrate into the skin and then extracting the puncture needle 23. Exemplarily, when the sensor 24 penetrates into the implanted organism, the second elastic member 6 is used to move the needle extraction seat 4 away from the organism, and the needle extraction seat 4 and the puncture needle 23 move away from the organism, so that the puncture needle 23 is separated from the organism.

[0724] The needle extraction mechanism can include the needle extraction seat 4, a passive mechanical driving device of the puncture needle 23, a guide needle, and one or more buckling devices. Alternatively, the needle extraction mechanism can include the needle extraction seat 4, a passive mechanical driving device of the puncture needle 23, a guide needle, and a buckling feature. The guide needle can include the needle seat 22 and the puncture needle 23.

[0725] The principle of the needle extraction mechanism includes that the needle extraction seat 4 and the needle seat 22 of the guide needle are buckled together by using clamping jaws, so that the guide needle can move with the guide needle fixing seat. In the initial position, the buckling device or the buckling feature buckles the needle extraction seat 4 tightly, so that the needle extraction seat 4 is kept in a predetermined position, and the passive mechanical driving device stores the potential energy required for driving at this time. After triggering the pushing, the pushing is performed to a position, and the pre-extraction needle or the multi-stage extraction needle is triggered. At this time, the buckling device or the buckling feature partially releases the needle extraction seat 4, and the needle extraction seat 4 is extracted away by a certain distance under the action of the passive mechanical driving device. When the pushing is performed to a position triggering the complete extraction of the needle, the buckling device or the buckling feature completely releases the needle extraction seat 4, and the passive mechanical driving device pushes the guide needle and the needle extraction seat 4 to a predetermined position, thereby completing the needle extraction action.

[0726] Exemplarily, the passive mechanical driving device of the puncture needle 23 can use the potential energy stored in the passive energy storage device to provide the kinetic energy of the needle extraction. Exemplarily, the passive mechanical driving device of the puncture needle 23 can include a compression spring, a tensile spring, a torsional spring, a clockwork spring, a high-pressure nitrogen cylinder, a vacuum cylinder, etc. Exemplarily, the second elastic member 6 in the foregoing embodiments is the passive mechanical driving device of the puncture needle 23, which is exemplified by using a compression spring.

[0727] Exemplarily, the clamping jaws buckling the needle extraction seat 4 and the guide needle can be on the needle seat 22 of the guide needle or on the needle extraction seat 4, and the number of clamping jaws can be two or more. The type of clamping can be planar clamping or vertical clamping. Exemplarily, the first cantilever 43 shown in FIGS. 16 and 17 is the clamping jaw buckling the needle extraction seat 4 and the guide needle. The clamping jaw buckling the needle extraction seat 4 and the guide needle is provided on the needle extraction seat 4 and is a vertical clamping jaw.

[0728] Exemplarily, the releasable fastening device can be an elastic buckle, a lever buckle, a screw buckle, a bevel gear, a bevel ratchet, etc., so that the guide needle and the needle extraction seat 4 can be kept in a predetermined design position and released after the pushing is completed.

[0729] In some embodiments, multi-stage needle extraction can be achieved by multi-stage cooperating features such as stepped grooves, stepped limiting ribs 961, and stepped limiting rods.

[0743] As shown in Fig. 78, in the present embodiment, the limiting buckle 221 of the needle seat 22 can serve as a clamping jaw of the guide needle and the needle extractor seat 4. That is, the clamping jaw of the guide needle and the needle extractor seat 4 can be on the needle seat 22 of the guide needle. The limiting buckle 221 of the needle seat 22 is a vertical clamping jaw.

[0744] Figs. 79 to 82 are partial sectional views of the physiological sign detection device 100 in the process of launching the sensor assembly 20 in the present embodiment. Figs. 79 to 82 illustrate the working process of the needle extraction mechanism in the present embodiment.

[0745] Fig. 79 illustrates the state that the physiological sign detection device 100 has just opened the shell cap assembly 8. The end of the elastic buckle 47 away from the lower side wall 943 of the base 5 abuts against the clamping hole 312. The elastic buckle 47 extends out of the clamping hole 312, and the pre-needle extraction pressing rib 512 and the needle extraction pressing rib 513 of the base 5 are oppositely arranged along the axial direction of the base 5. At this time, the end of the needle seat 22 provided with a screw thread (the end connected with the sealed bottle 29) protrudes from the adhesive member 28 of the sensor assembly 20. The clamping jaw of the guide needle is buckled with the needle extractor seat 4.

[0746] Exemplarily, the elastic buckle 47 can include an inclined section 471, which is arranged at an angle with the bottom plate 32 of the bracket 3. In some embodiments, the angle between the inclined section 471 and the bottom plate 32 of the bracket 3 is A. A is an acute angle. For example, A can be in the range of 30° to 80°. It can be understood that the larger A is, the smaller the force required to push the elastic buckle 47 inward, and the smaller the space occupied by the elastic buckle 47.

[0747] As shown in FIGS. 79 and 80, when the first elastic member 2 exerts a downward force on the bracket 3, the bracket 3 drives the needle holder 4 to move downward, and the bracket 3 moves to the first position, the middle part of the elastic buckle 47 is abutted by the needle extraction pressing rib 512 and is deformed by extrusion, the elastic buckle 47 abuts against the second step surface 3122, the first step surface 3121 and the second step surface 3122 have a height difference in the axial direction, at this time, the needle holder 4 is released from the space of the height difference, and the needle holder 4 moves upward relative to the bracket 3 under the action of the second elastic member 6. The clamping jaw of the guide needle is buckled with the needle holder 4, the needle holder 4 drives the needle seat 22 to move upward relative to the bracket 3 by a distance, so that the threaded end of the needle seat 22 can move upward relative to the adhesive member 28 of the sensor assembly 20. At this time, the end surface of the threaded end of the needle seat 22 moves upward and is substantially flush with the adhesive member 28 or is located on the side of the adhesive member 28 close to the needle holder 4. The pre-extraction needle action is realized.

[0748] As shown in FIGS. 80 and 81, under the action of the first elastic member 2, the bracket 3 continues to move downward, and when the bracket 3 moves to the second position, the middle part of the elastic buckle 47 abuts against the needle extraction pressing rib 513, and the needle extraction pressing rib 513 on the base 5 further extrudes the elastic buckle 47, so that the elastic buckle 47 is completely separated from the second step surface 3122 and is located on the inner side of the side plate of the bracket 3. The bracket 3 continues to move downward, the bracket 3 moves to the third position, the sensor assembly 20 abuts against the biological body 30, and the adhesive member 28 of the sensor assembly 20 contacts the skin of the user. The implantation action is completed.

[0749] As shown in FIGS. 81 and 82, the adhesive member 28 of the sensor assembly 20 can be fixed on the skin of the user. Under the action of the second elastic member 6, the guide needle is completely extracted, and the needle extraction action is completed.

[0750] It can be understood that the present embodiment shows a segmented needle extraction design, and the pre-extraction needle can lift the puncture needle 23 by a distance, so that the threaded plastic on the needle seat 22 is retracted in advance during the implantation process. The plastic part is prevented from contacting the skin and causing extrusion to the wound.

[0751] In the present embodiment, the puncture needle 23 is a passive mechanical driving device (i.e., the second elastic member 6), which is exemplified by a compression spring.

[0752] In some embodiments, the same parts as in the previous embodiments are not described again. FIG. 83 is a schematic diagram of still another embodiment of the physiological sign detection device 100 shown i...
