Description

Technical Field

[0001] This application relates to the field of sensor implantation technology, and in particular to an implanter, implantation device and detection system. Background Technology

[0002] With the rapid development of medical technology, biosensors have gained widespread attention due to their significant advantage of being able to monitor human physiological parameters in real time and accurately. These biosensors can continuously measure a variety of key physiological parameters such as blood oxygen concentration, blood glucose concentration, lactate concentration, and uric acid concentration, thereby providing comprehensive and accurate data support for disease diagnosis and treatment.

[0003] To achieve precise implantation of such biosensors, implanters have been developed. An implanter is a medical device used to implant tiny devices such as biosensors into implantation sites such as under the skin. During use, the biosensor is installed on the implanter. With the push of the implanter, the puncture needle carrying the sensor is inserted into the implantation site. After implantation, the puncture needle is withdrawn with the implanter, leaving only the sensor at the implantation site for real-time monitoring of the body's physiological parameters.

[0004] Among them, how to design implanters to reduce the trauma caused by puncture needles during implantation has become one of the important topics in the industry. Summary of the Invention

[0005] Embodiments of this application provide an implanter, an implantation device, and a detection system to address the problem of significant puncture damage to the implantation site caused by implanters in related technologies.

[0006] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0007] In a first aspect, embodiments of this application provide an implanter, including a housing, a sensor bracket, a first elastic element, and a first snap-fit ​​structure; the housing has an abutment end for abutting an implantation site of a biological organism, and an inner cavity of the housing extends through the abutment end; the sensor bracket is disposed in the inner cavity of the housing and is used to mount a sensor assembly, the sensor assembly including a sensor and a puncture needle for implanting the sensor into the implantation site; the sensor bracket is movable relative to the housing along a first direction between a first initial position and an implantation position, the sensor bracket being closer to the abutment end when in the implantation position than when in the first initial position; the first elastic element is used to guide the sensor... The sensor bracket is subjected to a first elastic force; the first snap-fit ​​structure has a first snap-fit ​​state and a first unlocked state. When the first snap-fit ​​structure is in the first snap-fit ​​state, the sensor bracket is locked in a first initial position by the first snap-fit ​​structure; when the first snap-fit ​​structure is in the first unlocked state, the sensor bracket moves to the implantation position under the action of the first elastic force; wherein, the sensor bracket is provided with a first cavity, the first cavity having a first cavity wall and a second cavity wall arranged along a first direction; the first cavity is provided with a filler, the filler can move in the first cavity under the action of inertial force and / or gravity, so that the filler contacts the first cavity wall or the second cavity wall.

[0008] In the implanter of this application embodiment, during the implantation of the sensor, when the first snap-fit ​​structure switches to the first unlocked state, the sensor bracket moves from a stationary state towards the implantation position under the action of the first elastic force of the first elastic element. The filler contacts the second cavity wall under the action of inertial force. At the instant of contact with the second cavity wall, the filler generates a first impact force on the second cavity wall. This first impact force can offset part of the first elastic force, thereby decelerating the sensor bracket and controlling its movement speed. This prevents the sensor bracket from moving too fast when it reaches the implantation position and being rebounded by the implantation site, causing increased oscillation. When the sensor bracket reaches the implantation position, its movement stops. The filler contacts the first cavity wall under the action of inertial force and gravity. At the instant of contact with the first cavity wall, the filler generates a second impact force on the first cavity wall. This second impact force can offset the elastic force generated by the release of the residual elastic potential energy of the first elastic element and the rebound force of the implantation site on the sensor bracket, thereby reducing the oscillation generated by the sensor bracket and thus mitigating the puncture damage caused by the puncture needle to the implantation site.

[0009] In some embodiments of the first aspect, the filler includes a plurality of filler bodies, each of which is movable within a first cavity under the action of inertial forces and / or gravity, so as to bring the filler body into contact with a first cavity wall or a second cavity wall. This configuration ensures that the impact force generated by the filler body on the first or second cavity wall is more uniform during the implantation of the sensor, thereby better reducing the vibration generated by the sensor support.

[0010] In some embodiments of the first aspect, the width d1 of the filler and the width d2 of the first cavity satisfy the following condition along the vertical direction of the first direction: d1 ≥ 0.25d2. This setting ensures that the filler has sufficient volume and mass, which is beneficial for controlling the movement of the filler along the first direction Z during the implantation of the sensor, thereby improving the vibration elimination effect on the sensor support.

[0011] In some embodiments of the first aspect, the filler has multiple filling layers along the first direction, and each filling layer has (2 to 5) fillers arranged side by side along the vertical direction of the first direction. This arrangement ensures that the fillers have sufficient volume and mass, which helps to increase the impact force generated by the filler on the first or second cavity wall during the implantation of the sensor, thereby improving the vibration elimination effect on the sensor support.

[0012] In some embodiments of the first aspect, the filler is a spherical structure. This configuration reduces the resistance of the filler during movement, enhances its mobility, and improves the impact force exerted by the filler on the first or second cavity wall during sensor implantation, thereby improving the vibration elimination effect on the sensor support.

[0013] In some embodiments of the first aspect, the filler is a solid structure. This configuration is beneficial for improving the mass and rigidity of the filler, and during the implantation of the sensor, it helps to increase the impact force generated by the filler on the first or second cavity wall, thereby improving the vibration elimination effect on the sensor support.

[0014] In some embodiments of the first aspect, the filler is made of one of steel, iron, aluminum, or copper. This configuration allows the filler to have lower elasticity and higher stiffness, which helps to increase the impact force generated by the filler on the first or second cavity wall during the implantation of the sensor, thereby improving the vibration elimination effect on the sensor support.

[0015] In some embodiments of the first aspect, the filler material is steel.

[0016] In some embodiments of the first aspect, the filler material is plastic with an elastic modulus of less than 100 MPa. This configuration allows the filler to have lower elasticity and higher stiffness, which helps to increase the impact force generated by the filler on the first or second cavity wall during the implantation of the sensor, thereby improving the vibration elimination effect on the sensor support.

[0017] In some embodiments of the first aspect, the volume V1 of the filler and the volume V2 of the first cavity satisfy the condition: 0.3V2≤V1≤0.7V2. This setting ensures that the filler has sufficient mass and ample space for movement, allowing the filler to generate a greater impact force on the first or second cavity wall during the implantation of the sensor, thereby improving the vibration elimination effect of the sensor support.

[0018] In some embodiments of the first aspect, the filler is a solid filler. This arrangement helps to reduce the sealing requirements of the first cavity.

[0019] In some embodiments of the first aspect, the filler is a liquid filler. The liquid filler may be water.

[0020] In some embodiments of the first aspect, the end of the sensor bracket near the abutment end is the outer end of the bracket, and a receiving cavity for mounting the sensor assembly is provided at the outer end of the bracket. A first cavity extends to the outer end of the bracket along a first direction and is spaced apart from the receiving cavity. With this configuration, when the sensor bracket moves to the implantation position, the impact force generated when the filler contacts the wall of the first cavity can better counteract the rebound force generated by the implantation site on the sensor bracket, thereby improving the vibration elimination effect of the sensor bracket.

[0021] In some embodiments of the first aspect, the receiving cavity includes a first receiving cavity and a second receiving cavity that are connected to each other. The first receiving cavity is disposed at the outer end of the stent and is used to house the sensor. The second receiving cavity is located on the side of the first receiving cavity away from the abutment end and is used to allow the end of the puncture needle away from the puncture end to extend into it. The first cavity is an annular cavity and is disposed around the second receiving cavity. The first cavity is spaced apart from both the first and second receiving cavities. This arrangement can make full use of the space surrounding the second receiving cavity, thereby avoiding excessive size of the sensor stent in the first direction Z, which is beneficial for controlling the volume of the implanter.

[0022] In some embodiments of the first aspect, the size of the first cavity along the first direction is less than half the size of the sensor support. This arrangement helps to increase the impact force of the filler on the first or second cavity wall during sensor implantation, thereby improving the vibration damping effect on the sensor support.

[0023] Secondly, embodiments of this application provide an implanter, including: a shell, a sensor bracket, a first elastic element, and a first snap-fit ​​structure; the shell includes an inner shell and an outer shell, the inner shell having an inner end and an abutment end, the inner end being located inside the outer shell, and the abutment end extending outside the outer shell and used to abut against the implantation site of a biological body, the inner cavity of the inner shell at least penetrating the abutment end; the sensor bracket is disposed in the inner cavity of the inner shell, the end of the sensor bracket near the abutment end being the outer end of the bracket, and a receiving cavity is provided at the outer end of the bracket for installing a sensor assembly, the sensor assembly including a sensor, and a puncture needle for implanting the sensor into the implantation site; the sensor bracket is movable relative to the inner shell along a first direction between a first initial position and an implantation position, the sensor bracket being closer to the abutment end when in the implantation position than when in the first initial position; the first elastic element is used to... The sensor bracket is subjected to a first elastic force; the first snap-fit ​​structure includes a first snap-fit ​​portion disposed on the inner shell and a second snap-fit ​​portion disposed on the sensor bracket. The first snap-fit ​​structure has a first snap-fit ​​state and a first unlocked state. When the first snap-fit ​​structure is in the first snap-fit ​​state, the first snap-fit ​​portion and the second snap-fit ​​portion snap together, and the sensor bracket is locked in a first initial position. When the first snap-fit ​​structure is in the first unlocked state, the first snap-fit ​​portion and the second snap-fit ​​portion separate, and the sensor bracket moves to the implantation position under the action of the first elastic force. The sensor bracket is provided with a first cavity, which has a first cavity wall and a second cavity wall arranged along a first direction. The first cavity is provided with a filler, which can move within the first cavity under the action of inertial force and / or gravity, so that the filler contacts the first cavity wall or the second cavity wall.

[0024] The beneficial effects of the implanter in this embodiment are the same as those of the implanter in the first aspect, and will not be repeated here.

[0025] In some embodiments of the second aspect, the filler includes a plurality of filler bodies, each of which can move within a first cavity under the action of inertial forces and / or gravity, so as to bring the filler body into contact with a first cavity wall or a second cavity wall. This configuration ensures that the impact force generated by the filler body on the first or second cavity wall is more uniform during the implantation of the sensor, thereby better reducing the vibration generated by the sensor support.

[0026] In some embodiments of the second aspect, the width d1 of the filler and the width d2 of the first cavity satisfy the following condition along the vertical direction of the first direction: d1 ≥ 0.25d2. This setting ensures that the filler has sufficient volume and mass, which is beneficial for controlling the movement of the filler along the first direction Z during the implantation of the sensor, thereby improving the vibration elimination effect on the sensor support.

[0027] In some embodiments of the second aspect, the filler has multiple filling layers along the first direction, and each filling layer has (2 to 5) fillers arranged side by side along the vertical direction of the first direction. This arrangement ensures that the fillers have sufficient volume and mass, which helps to increase the impact force generated by the filler on the first or second cavity wall during the implantation of the sensor, thereby improving the vibration elimination effect on the sensor support.

[0028] In some embodiments of the second aspect, the filler is a spherical structure. This configuration reduces the resistance of the filler during movement, enhances its mobility, and improves the impact force exerted by the filler on the first or second cavity wall during sensor implantation, thereby improving the vibration elimination effect on the sensor support.

[0029] In some embodiments of the second aspect, the filler is a solid structure. This configuration is beneficial for improving the quality and rigidity of the filler, and during the implantation of the sensor, it helps to increase the impact force generated by the filler on the first or second cavity wall, thereby improving the vibration elimination effect on the sensor support.

[0030] In some embodiments of the second aspect, the filler material is one of steel, iron, aluminum, or copper. This configuration allows the filler to have lower elasticity and higher stiffness, which helps to increase the impact force generated by the filler on the first or second cavity wall during the implantation of the sensor, thereby improving the vibration elimination effect on the sensor support.

[0031] In some embodiments of the first aspect, the filler material is steel.

[0032] In some embodiments of the second aspect, the filler material is plastic, and the elastic modulus of the plastic is less than MPa. This configuration allows the filler to have lower elasticity and higher stiffness, which helps to increase the impact force generated by the filler on the first or second cavity wall during the implantation of the sensor, thereby improving the vibration elimination effect on the sensor support.

[0033] In some embodiments of the second aspect, the volume V1 of the filler and the volume V2 of the first cavity satisfy the condition: 0.3V2≤V1≤0.7V2. This setting ensures that the filler has sufficient mass and ample space for movement, allowing the filler to generate a greater impact force on the first or second cavity wall during the implantation of the sensor, thereby improving the vibration elimination effect of the sensor support.

[0034] In some embodiments of the second aspect, the filler is a solid filler. This arrangement helps to reduce the sealing requirements of the first cavity.

[0035] In some embodiments of the second aspect, the filler is a liquid filler. The liquid filler may be water.

[0036] In some embodiments of the second aspect, the first cavity extends to the outer end of the stent along the first direction and is spaced apart from the receiving cavity. This arrangement allows the impact force generated when the sensor stent moves to the implantation position, when the filler contacts the wall of the first cavity, to better counteract the rebound force generated by the implantation site on the sensor stent, thereby improving the vibration elimination effect of the sensor stent.

[0037] In some embodiments of the second aspect, the receiving cavity includes a first receiving cavity and a second receiving cavity that are connected to each other. The first receiving cavity is disposed at the outer end of the stent and is used to house the sensor. The second receiving cavity is located on the side of the first receiving cavity away from the abutment end and is used to allow the end of the puncture needle away from the puncture end to extend into it. The first cavity is an annular cavity and is disposed around the second receiving cavity. The first cavity is spaced apart from both the first and second receiving cavities. This arrangement can make full use of the space surrounding the second receiving cavity, thereby avoiding excessive size of the sensor stent in the first direction Z, which is beneficial for controlling the volume of the implanter.

[0038] In some embodiments of the second aspect, the size of the first cavity along the first direction is less than half the size of the sensor support. This arrangement helps to increase the impact force of the filler on the first or second cavity wall during sensor implantation, thereby improving the vibration reduction effect on the sensor support.

[0039] In some embodiments of the second aspect, the implanter further includes a needle aspiration seat, a second elastic element, and a second locking structure; the sensor support also has a second cavity, which communicates with the receiving cavity and is spaced apart from the first cavity; the needle aspiration seat is at least partially disposed in the second cavity and is used to connect with a puncture needle, the needle aspiration seat is movable relative to the sensor support along a first direction between a second initial position and a needle aspiration position, the needle aspiration seat being further away from the outer end of the support when it is in the needle aspiration position than when it is in the second initial position; the second elastic element is used to apply a second elastic force to the needle aspiration seat; the second locking structure includes a needle seat locking portion disposed on the needle aspiration seat and a support locking portion disposed on the sensor support, the second locking structure having a second locking state and a second unlocking state; when the second locking structure is in the second locking state, the needle seat locking portion engages with the support locking portion, and the needle aspiration seat is locked in the second initial position; when the second locking structure is in the second unlocking state, the needle seat locking portion separates from the support locking portion, and the needle aspiration seat moves to the needle aspiration position under the action of the second elastic force. This design increases the safety of the implantation device, preventing the protruding puncture needle from scratching other parts of the user's body during the retraction process.

[0040] In some embodiments of the second aspect, the needle seat locking portion includes an elastic arm connected to the needle drawer seat and a locking protrusion disposed on the elastic arm; the bracket locking portion is provided with a locking through hole, which is opposite to the side wall of the inner shell; when the second locking structure is in the second locking state, the locking protrusion extends into the locking through hole, so that the needle seat locking portion and the bracket locking portion are locked together. With this configuration, the unlocking method of the second locking structure is relatively simple and direct, thereby simplifying the setting of the unlocking component and eliminating the need for a complex unlocking mechanism.

[0041] In some embodiments of the second aspect, the second locking structure includes a needle seat unlocking part disposed on the side wall of the inner shell. The bracket locking part has a sliding groove extending along a first direction and communicating with a locking through hole. The needle seat unlocking part slides in conjunction with the sliding groove. When the sensor bracket moves to the implantation position, the needle seat unlocking part can slide relative to the sliding groove to the position of the locking through hole and press the locking protrusion, causing the locking protrusion to disengage from the locking through hole, thereby placing the second locking structure in a second unlocked state. With this configuration, the unlocking of the second locking structure is performed automatically during sensor implantation, without manual operation, thus simplifying the sensor implantation process.

[0042] In some embodiments of the second aspect, the slide groove includes a first slide groove section and a second slide groove section. The first slide groove section is located on the side of the snap-fit ​​hole near the outer end of the bracket and is connected to the snap-fit ​​hole; the second slide groove section is located on the side of the snap-fit ​​hole away from the outer end of the bracket and is connected to the snap-fit ​​hole. This arrangement allows the snap-fit ​​protrusion to disengage more easily from the snap-fit ​​hole, thereby making the unlocking of the second snap-fit ​​structure smoother.

[0043] In some embodiments of the second aspect, the groove includes a first groove segment located on the side of the locking hole near the outer end of the bracket and communicating with the locking hole; the bracket locking part is a sheet-like structure and includes a first segment and a second segment arranged along a first direction, the inner surface of the first segment protruding beyond the inner surface of the second segment, so that the thickness of the first segment is greater than the thickness of the second segment; the first groove is disposed on the first segment and penetrates the inner surface of the first segment, and the locking holes are all disposed on the second segment and penetrate the inner surface of the second segment. With this configuration, when the sensor bracket moves to the implantation position, the locking protrusion of the needle seat locking part is more easily disengaged from the inside of the locking hole under the pressure of the needle seat unlocking part, thereby making the unlocking of the second locking structure smoother.

[0044] In some embodiments of the second aspect, the maximum depth to which the needle seat unlocking part extends into the first groove is greater than the thickness of the second segment. With this configuration, when the sensor holder moves to the implantation position, the locking protrusion of the needle seat locking part can be easily and completely squeezed out of the locking through-hole by the needle seat unlocking part, thereby making the unlocking of the second locking structure smoother.

[0045] In some embodiments of the second aspect, a first guide slope is provided at the end of the pin seat unlocking part away from the abutment end. The first guide slope is inclined relative to the first direction and is used to contact the locking protrusion. With this configuration, the first guide slope can guide the locking protrusion, making it easier for the locking protrusion to disengage from the locking through hole under the pressure of the pin seat unlocking part, thereby making the unlocking of the second locking structure more stable and smooth.

[0046] In some embodiments of the second aspect, the snap-fit ​​protrusion is provided with a second guide slope, which is inclined relative to the first direction and is used to contact the pin seat unlocking part. With this configuration, the second guide slope can guide the snap-fit ​​protrusion, making it easier for the snap-fit ​​protrusion to disengage from the snap-fit ​​through hole under the pressure of the pin seat unlocking part, thus making the unlocking of the second snap-fit ​​structure more stable and smooth.

[0047] In some embodiments of the second aspect, a first receiving groove is provided on the side wall of the sensor bracket, and a limiting arm is provided on the sensor bracket, the limiting arm being disposed in the first receiving groove; a rib is provided on the side wall of the inner shell, the rib extending along a first direction; when the sensor bracket is in the implantation position, the limiting arm engages with one end of the rib to prevent the sensor bracket from extending outward from the inner shell. This arrangement limits the range of movement of the sensor bracket along the first direction, thereby allowing the sensor bracket to move to a preset position when in the implantation position. Simultaneously, placing the limiting arm in the first receiving groove reduces the space occupied by the limiting arm on the inner and outer sides of the sensor bracket, thus facilitating the optimized layout of the structure on the sensor bracket.

[0048] In some embodiments of the second aspect, a second receiving groove is provided on the side wall of the sensor bracket, and the bracket locking part is disposed in the second receiving groove. This arrangement can reduce the space occupied by the bracket locking part on the inner and outer sides of the sensor bracket.

[0049] In some embodiments of the second aspect, the first latching portion includes a first elastic latching arm and a protrusion. The first elastic latching arm includes a first arm segment connected to the inner shell and a second arm segment connected to the first arm segment. The protrusion is disposed on the second arm segment, and the first arm segment is inclined relative to the first direction. The second latching portion is a latching opening disposed on the side wall of the sensor bracket. When the first latching structure is in the first latching state, the protrusion extends into the second latching portion to latch the first latching portion and the second latching portion. This arrangement can avoid frictional wear caused by the movement of the first latching portion with the moving parts, thereby helping to reduce the probability of damage to the first latching portion. At the same time, the first arm segment 2 is inclined relative to the first direction Z, which helps to increase the elasticity of the first latching portion, so as to facilitate the elastic deformation of the first latching portion and its separation from the second latching portion 43.

[0050] In some embodiments of the second aspect, the outer shell is slidably connected to the inner shell along a first direction; the first locking structure includes a bracket unlocking part, which is disposed on the inner wall of the outer shell and abuts against the first arm segment; when the outer shell moves relative to the inner shell towards the abutting end, the bracket unlocking part squeezes the first arm segment, causing the first elastic locking arm to elastically deform and drive the protrusion to disengage from the second locking part, thereby placing the first locking structure in a first unlocked state. This configuration allows unlocking to be achieved by moving the bracket unlocking part using the outer shell, eliminating the need for additional moving parts. Furthermore, it simplifies the operation steps and facilitates the operation of the implant.

[0051] In some embodiments of the second aspect, the bracket unlocking part is provided with an abutment slope, which is inclined relative to the first direction and contacts the first arm segment. This arrangement can increase the contact area between the bracket unlocking part and the first elastic locking arm, thereby avoiding damage to the first elastic locking arm caused by the sharp edges of the bracket unlocking part.

[0052] In some embodiments of the second aspect, the second arm segment is located on the outer side of the sidewall of the sensor bracket, along the first direction and pointing from the inner end of the inner shell to the abutment end, and the distance from the first arm segment to the central axis of the inner shell gradually decreases. This arrangement avoids the first elastic locking arm from occupying the internal space of the sensor bracket, thereby preventing interference between the first elastic locking arm and the internal structure of the sensor bracket.

[0053] In some embodiments of the second aspect, a retaining arm receiving groove is provided on the side wall of the inner shell; the retaining arm receiving groove extends along a first direction, and a first elastic retaining arm is disposed in the retaining arm receiving groove; an outer shell guide portion is provided on the side wall of the inner shell, the outer shell guide portion including a first guide portion and a second guide portion, the first guide portion and the second guide portion being located at opposite side edges of the retaining arm receiving groove along the groove width direction; a sliding guide groove is provided on the side wall of the outer shell, the sliding guide groove extending along the first direction, the outer shell guide portion slidingly engaging with the sliding guide groove, so that the outer shell is slidably connected to the inner shell along the first direction. This arrangement can prevent the outer shell from shaking or rotating relative to the inner shell, thereby making the movement of the outer shell relative to the inner shell along the first direction Z more stable. At the same time, it can also prevent the outer shell guide portion from occupying space in other positions on the side wall of the inner shell, thereby making the structure on the side wall of the inner shell more compact.

[0054] In some embodiments of the second aspect, the implanter further includes a connector, which includes a connector body and a second elastic locking arm disposed at the edge of the connector body. The connector body is disposed at the inner end of the support, which is the end of the sensor support away from the abutment end. A locking hole is provided on the side wall of the sensor support. The second elastic locking arm engages with the locking hole, and the edge of the connector body abuts against the inner end of the support, thereby fixing the connector relative to the sensor support along a first direction. One end of the first elastic member is connected to the outer shell, and the other end of the first elastic member extends from the inner end of the shell into the inner shell and is connected to the connector body. This configuration facilitates the installation of the connector and the sensor support, eliminating the need for tightening fasteners and thus shortening the installation time of the connector.

[0055] In some embodiments of the second aspect, the second elastic locking arm extends into the inner side wall of the sensor bracket and engages with the locking hole. This arrangement facilitates the unlocking of the locking structure between the connector and the sensor bracket, thereby making it easier to detach the connector from the sensor bracket.

[0056] Thirdly, embodiments of this application provide an implantation device, including the implanter described in the first or second aspect, and a sensor assembly mounted on a sensor holder. The sensor assembly includes a sensor and a puncture needle for implanting the sensor into an implantation site in a living organism.

[0057] The beneficial effects of the implantation device in this embodiment are the same as those of the implanter in the first aspect, and will not be repeated here.

[0058] Fourthly, embodiments of this application provide a detection system, including the implantable device described in the third aspect, and a display terminal device, wherein the display terminal device is communicatively connected to the sensor of the implantable device and is used to display the physiological information detected by the sensor.

[0059] The beneficial effects of the detection system in this application embodiment are the same as those of the implant in the first aspect, and will not be repeated here.

[0060] In some embodiments of the fourth aspect, the display terminal device may be a mobile phone, tablet computer, smartwatch, or laptop computer. Attached Figure Description

[0102] With the rapid development of medical technology, biosensors have gained widespread attention due to their significant advantage of being able to monitor human physiological parameters in real time and accurately. These biosensors can continuously measure various key physiological parameters such as blood oxygen concentration, blood glucose concentration, lactate concentration, and uric acid concentration, thereby providing comprehensive and accurate data support for disease diagnosis and treatment. Taking continuous glucose monitoring as an example, implantable blood glucose sensors can monitor blood glucose signals in real time and transmit the data to a display terminal device, thus achieving the goal of uninterrupted and visualized blood glucose monitoring around the clock.

[0103] To achieve precise implantation of such biosensors, implanters have been developed. An implanter is a medical device used to implant tiny devices such as biosensors into implantation sites such as under the skin. During use, the biosensor is installed on the implanter. With the push of the implanter, the puncture needle carrying the sensor is inserted into the implantation site. After implantation, the puncture needle is withdrawn with the implanter, leaving only the sensor at the implantation site for long-term real-time monitoring of the body's physiological parameters.

[0104] Among them, how to design implanters to reduce the trauma caused by puncture needles during implantation has become one of the important topics in the industry.

[0105] Figure 1a This is a diagram showing the state of an implantable device during the implantation process, as described in the related technology. Figure 1b This refers to the state of an implantable device during the implantation process in related technologies. Figure 2 , Figure 1c Figure 3 shows the state of an implantable device during the implantation process in a related technology.

[0106] like Figure 1a As shown, the implantation device includes an implanter 100 and a sensor assembly 300. The implanter 100 includes a housing 1, a sensor support 2, a first elastic element 31, and a first snap-fit ​​structure 41.

[0107] The housing 1 includes an inner shell 11 and an outer shell 12, the inner shell 11 having an inner end 11b (e.g. Figure 1a The upper end of the inner shell 11 shown) and the abutment end 11a (e.g.) Figure 1a The lower end of the inner shell 11 is shown. The inner end 11b is located inside the outer shell 12, and the abutment end 11a extends out of the outer shell 12 and is used to abut the implantation site 600 of the organism. The inner cavity of the inner shell 11 penetrates the inner end 11b and the abutment end 11a.

[0108] Sensor bracket 2 is disposed within inner housing 11. Sensor bracket 2 is used to mount sensor assembly 300, sensor assembly 300 including sensor 310 and puncture needle 320 for implanting sensor 310 into implantation site 600. Sensor bracket 2 can be positioned at a first initial position along a first direction Z (e.g., Figure 1a (as shown in the image) and implantation location (e.g.) Figure 1b The positions shown can be moved relative to the inner shell 11.

[0109] The first elastic element 31 is connected between the inner wall of the housing 12 and the sensor bracket 2, and is used to apply a first elastic force to the sensor bracket 2. The first elastic element 31 can be a spring, with one end of the spring connected to the inner wall of the housing 12 and the other end of the spring connected to the sensor bracket 2.

[0110] The first latching structure 41 includes a first latching portion 42 disposed on the inner shell 11 and a second latching portion 43 disposed on the sensor bracket 2. The first latching structure 41 has a first latching state and a first unlocking state, such as... Figure 1a As shown, when the first latching structure 41 is in the first latching state, the first latching part 42 and the second latching part 43 are latched together, and the sensor bracket 2 is locked in the first initial position; as Figure 1b As shown, when the first locking structure 41 is in the first unlocked state, the first locking part 42 and the second locking part 43 are separated, and the sensor bracket 2 moves to the implantation position under the force of the first elastic member 31.

[0111] The first latching structure 41 includes a bracket unlocking part 44, which can be a protrusion provided on the inner wall of the housing 12. The bracket unlocking part 44 abuts against the first latching part 42 and is used to unlock the first latching structure 41, so that the first latching structure 41 switches from the first latching state to the first unlocking state.

[0112] The process of implanting sensor 310 into implanter 100 is as follows: Figure 1a As shown, the abutting end 11a of the inner shell 11 is placed against the implantation site 600, and an action is applied to the outer shell 12, causing the outer shell 12 to move relative to the inner shell 11 in a direction closer to the abutting end 11a (e.g., downward in the figure). The bracket unlocking part 44, driven by the outer shell 12, moves towards the abutting end 11a and presses against the first locking part 42. The first locking part 42 undergoes elastic deformation under pressure to separate from the second locking part 43. At this time, as... Figure 1b As shown, the first locking structure 41 is in the first unlocked state, the first elastic element 31 is triggered and releases its elastic potential energy. Under the action of the first elastic force of the first elastic element 31, the sensor bracket 2 moves along the first direction to the implantation position. The body part of the sensor 310 is attached to the epidermis of the implantation site 600, and the implantation part of the sensor 310 is inserted into the implantation site 600 under the action of the puncture needle 320. After the implantation of the sensor 310 is completed, as... Figure 1c As shown, the puncture needle 320 is withdrawn with the implanter 100, while the sensor 310 remains at the implantation site 600 to monitor physiological parameters in real time.

[0113] In the implantation process of the implanter 100 in the related technology, when the first locking structure 41 switches to the first unlocking state, the elastic potential energy of the first elastic element 31 is released in a short time. The sensor bracket 2 moves at a relatively fast speed under the action of the first elastic element 31, and the speed is not easy to control. This makes it easy for the sensor bracket 2 to bounce off the implantation site 600 when it moves to the implantation position, causing oscillation. At the same time, when the sensor bracket 2 moves to the implantation position, the first elastic element 31 still has residual elastic potential energy. The release of this residual elastic potential energy will aggravate the oscillation of the sensor bracket 2, causing the sensor bracket 2 to repeatedly "slap" the wound of the implantation site 600, thereby aggravating the puncture damage of the puncture needle 320 to the implantation site 600.

[0114] Therefore, this application provides an implanter, an implantation device, and a detection system. By providing a movable filler in the cavity of the sensor holder of the implanter, the filler can contact the cavity wall under inertia during the sensor implantation process to generate a "dead hammer effect", thereby reducing the vibration caused by the rebound of the sensor holder at the implantation site and thus reducing the puncture damage to the implantation site.

[0115] Figure 2 This is a schematic diagram of the detection system in the embodiments of this application.

[0116] like Figure 2 As shown, the detection system includes an implantation device 400 and a display terminal device 500.

[0117] The implantation device 400 includes an implanter 100 and a sensor assembly 300, which includes a sensor 310 and a puncture needle 320 for implanting the sensor 310 into an implantation site 600 (such as the arm or abdomen) in a living organism. A display terminal device 500 is communicatively connected to the sensor 310 and is used to display the detected physiological information.

[0118] The sensor 310 is used to detect physiological information at the implantation site 600. This physiological information may include physiological parameters such as blood oxygen concentration, blood glucose concentration, lactate concentration, and uric acid concentration. The display terminal device 500 can communicate with the sensor 310 via Bluetooth or Near Field Communication (NFC) technology. The display terminal device 500 can be a terminal device with a display screen, such as a mobile phone, tablet computer, smartwatch, or laptop computer.

[0119] Figure 3a This is Figure 1, showing the state of the implantation device 400 in the first embodiment of this application during the implantation process. Figure 3b for Figure 3aA schematic diagram of the structure of the sensor assembly 300. Figure 3c for Figure 3b A cross-sectional view of sensor assembly 300 in the diagram. Figure 3d This describes the state of the implantation device 400 in the first embodiment of this application during the implantation process. Figure 2 , Figure 3e Figure 3 shows the state of the implantation device 400 in the first embodiment of this application during the implantation process. Figure 3f This describes the state of the implantation device 400 in the first embodiment of this application during the implantation process. Figure 4 .

[0120] like Figure 3a As shown, the implantation device 400 includes an implanter 100 and a sensor assembly 300. The implanter 100 includes a housing 1, a sensor support 2, a first elastic element 31, and a first snap-fit ​​structure 41.

[0121] The shell 1 has an abutment end 11a, which is used to abut against the implantation site 600 of the organism, and the inner cavity of the shell 1 extends through the abutment end 11a.

[0122] In some embodiments, such as Figure 3a As shown, the housing 1 may include an inner shell 11 (also referred to as a base) and an outer shell 12, the inner shell 11 having an inner end 11b (e.g. Figure 3a The upper end of the inner shell 11 shown) and the abutment end 11a (e.g.) Figure 3a The lower end of the inner shell 11 is shown. The inner end 11b is located inside the outer shell 12, and the abutment end 11a extends out of the outer shell 12 and is used to abut the implantation site 600. The inner cavity of the inner shell 11 at least penetrates the abutment end 11a. Figure 3a The inner cavity of the inner shell 11 penetrates the abutment end 11a and the inner shell end 11b.

[0123] Among them, such as Figure 3a As shown, the outer shell 12 can be a sleeve-like structure with one end open and the other end closed (i.e., the outer shell 12 has an open end and a closed end), and the inner shell 11 can be a sleeve-like structure with openings at both ends. The abutting end 11a of the inner shell 11 extends from the open end of the outer shell 12 (e.g., Figure 3a The lower end of the outer shell 12 shown extends out. Of course, the structure of the outer shell 12 and the inner shell 11 is not limited to this, and the outer shell 12 and the inner shell 11 can also be set to other structures according to the actual situation.

[0124] like Figure 3a As shown, the sensor bracket 2 is disposed within the inner housing 11. The sensor bracket 2 is used to mount the sensor assembly 300, which includes a sensor 310 and a puncture needle 320 for implanting the sensor 310 into the implantation site 600. The sensor bracket 2 can be positioned at a first initial position along a first direction Z (e.g., ...). Figure 3a(as shown in the image) and implantation location (e.g.) Figure 3e The sensor bracket 2 moves relative to the inner shell 11 between the positions shown, and when it is in the implantation position it is closer to the abutment end 11a than when it is in the first initial position.

[0125] In some embodiments, such as Figure 3a As shown, the sensor bracket 2 has an outer end 2a (e.g., Figure 3a The lower end of the sensor bracket 2 shown) and the inner end 2b of the bracket (e.g.) Figure 3a The upper end of the sensor bracket 2 shown is shown. The outer end 2a of the bracket is the end of the sensor bracket 2 near the abutment end 11a, and the inner end 2b of the bracket is the end of the sensor bracket 2 near the inner end 11b of the shell. Figure 3e As shown, when the sensor bracket 2 is in the implantation position, the outer end 2a of the bracket is located at the position of the abutment end 11a.

[0126] In some embodiments, such as Figure 3a As shown, a receiving cavity 22 is provided at the outer end 2a of the bracket, and the receiving cavity 22 is used to install the sensor assembly 300.

[0127] In some embodiments, such as Figure 3b and Figure 3c As shown, the sensor 310 includes a sensor housing 311, a sensor body 312, and a sensor implantation part 313. The sensor housing 311 can be an annular housing with a central through hole 314. A puncture needle 320 passes through the central through hole 314. The sensor implantation part 313 can be an L-shaped structure. A portion of the sensor implantation part 313 extends into the sensor housing 311 and is connected to the sensor body 312. The other portion of the sensor implantation part 313 passes through the puncture needle 320 and can be inserted into the implantation site 600 under the action of the puncture needle 320. It should be noted that the above is only an example, and the sensor 310 in this embodiment is not limited to this.

[0128] In some embodiments, such as Figure 3b and Figure 3c As shown, the puncture needle 320 includes a needle body 322 and a puncture needle seat 323. One end of the needle body 322 is the puncture end 321, and the other end of the needle body 322 is provided with the puncture needle seat 323. The puncture needle seat 323 is disposed in the central through hole 314 and is connected to the sensor bracket 2. The cross-sectional shape of the needle body 322 is U-shaped, and the opening 3221 of the needle body 322 is disposed on the side facing the sensor body 312. The opening 3221 of the needle body 322 is used for the sensor implantation part 313 to extend into.

[0129] The shape of the sensor bracket 2 is not unique; in some embodiments, such as... Figure 3aAs shown, the sensor bracket 2 can be a stepped shaft structure, including a small shaft segment and a large shaft segment connected together. The diameter of the small shaft segment is smaller than the diameter of the large shaft segment. The large shaft segment is located on the side of the small shaft segment near the abutting end 11a. The outer end 2a of the bracket is one end of the large shaft segment, and the inner end 2b of the bracket is one end of the small shaft segment. Of course, the sensor bracket 2 is not limited to a stepped shaft structure. The sensor bracket 2 can also be configured into other structures, such as a sleeve structure, depending on the actual situation.

[0130] like Figure 3a As shown, the first elastic element 31 is used to apply a first elastic force to the sensor bracket 2.

[0131] The type of the first elastic element 31 is not unique; in some embodiments, such as... Figure 3a As shown, the first elastic element 31 can be a spring. One end of the first elastic element 31 is connected to the inner wall of the outer shell 12, and the other end of the first elastic element 31 is connected to the inner end 2b of the bracket. However, it is not limited to this. In some other embodiments, the first elastic element 31 can also be a spring sheet. The spring sheet can be V-shaped, W-shaped, wavy, etc. One end of the spring sheet is connected to the inner wall of the outer shell 12, and the other end of the spring sheet is connected to the inner end 2b of the bracket.

[0132] The first card-connecting structure 41 has a first card-connecting state and a first unlocking state, such as Figure 3a As shown, when the first locking structure 41 is in the first locking state, the sensor bracket 2 is locked in the first initial position by the first locking structure 41; as Figure 3d and Figure 3e As shown, when the first snap-fit ​​structure 41 is in the first unlocked state, the sensor bracket 2 moves to the implantation position under the force of the first elastic member 31.

[0133] In some embodiments, the first snap-fit ​​structure 41 described above can be the following structure: such as Figure 3a As shown, the first snap-fit ​​structure 41 includes a first snap-fit ​​portion 42 disposed on the inner shell 11 and a second snap-fit ​​portion 43 disposed on the sensor bracket 2, as follows: Figure 3a As shown, when the first latching structure 41 is in the first latching state, the first latching part 42 and the second latching part 43 are latched together, and the sensor bracket 2 is locked in the first initial position; as Figure 3d and Figure 3e As shown, when the first locking structure 41 is in the first unlocked state, the first locking part 42 and the second locking part 43 are separated, and the sensor bracket 2 moves to the implantation position under the force of the first elastic member 31.

[0134] Among them, such as Figure 3aAs shown, the first engaging portion 42 includes a first elastic engaging arm 421 and a protrusion 424. The first elastic engaging arm 421 includes a first arm segment 422 connected to the inner shell 11 and a second arm segment 423 connected to the first arm segment 422. The protrusion 424 is disposed on the second arm segment 423, and the first arm segment 422 is inclined relative to the first direction Z. The second engaging portion 43 is an engaging opening disposed on the side wall of the sensor bracket 2. When the first engaging structure 41 is in the first engaging state, the protrusion 424 extends into the second engaging portion 43, so that the first engaging portion 42 and the second engaging portion 43 engage. The engaging opening can be a hole or a groove, and is not specifically limited here.

[0135] By placing the first engaging portion 42 on the inner shell 11 (stationary component), frictional wear caused by the movement of the first engaging portion 42 with the moving component can be avoided when the first engaging portion 42 separates from the second engaging portion 43, thereby reducing the probability of damage to the first engaging portion 42. Simultaneously, the first arm segment 422 is inclined relative to the first direction Z, which increases the elasticity of the first engaging portion 42, facilitating elastic deformation and separation from the second engaging portion 43.

[0136] The unlocking method of the first latching structure 41 is not unique. In some embodiments, the first latching structure 41 can be unlocked by moving the outer casing 12, as shown in the following example. Figure 3a and Figure 3b As shown, the outer shell 12 is slidably connected to the inner shell 11 along the first direction Z. The first snap-fit ​​structure 41 includes a bracket unlocking part 44, which is disposed on the inner wall of the outer shell 12 and abuts against the first arm segment 422.

[0137] When the outer casing 12 moves towards the abutment end 11a (for example) Figure 3a When the bracket unlocking part 44 moves relative to the inner shell 11 in the downward direction, it presses the first arm segment 422, causing the first elastic locking arm 421 to undergo elastic deformation and drive the protrusion 424 to disengage from the second locking part 43, thereby putting the first locking structure 41 in the first unlocked state.

[0138] By mounting the stent unlocking part 44 on the outer shell 12, the outer shell 12 can be used to move the stent unlocking part 44 to unlock it, eliminating the need for additional moving parts and thus simplifying the structure of the implanter 100. Furthermore, by moving the outer shell 12, the first locking structure 41 can be unlocked. When the user applies force to bring the abutting end 11a of the inner shell 11 against the implantation site 600, this force also moves the outer shell 12 closer to the abutting end 11a to unlock it. This simplifies the operation and makes the implanter 100 easier to use.

[0139] The shape of the bracket unlocking part 44 is not unique; in some embodiments, such as... Figure 3a As shown, the bracket unlocking part 44 can be a block structure; however, it is not limited to this, the bracket unlocking part 44 can also be a columnar structure, a spherical structure, etc.

[0140] In some embodiments, such as Figure 3a As shown, the first latching part 42 is located at the inner end 11b of the inner shell 11, and the bracket unlocking part 44 is located at the closed end of the outer shell 12 (e.g., Figure 3a On the shell wall of the upper end of the outer shell 12 shown in the figure.

[0141] In some embodiments, such as Figure 3a As shown, multiple sets of the first latching structure 41 can be provided (e.g., two or three sets), that is, the number of first latching structures 42 is multiple (e.g., two or three), and the multiple first latching structures 42 are arranged circumferentially along the inner shell 11; the number of second latching structures 43 is multiple (e.g., two or three), and the multiple second latching structures 43 are arranged circumferentially along the sensor bracket 2, with each second latching structure 43 latching into its corresponding first latching structure 42; the number of bracket unlocking parts 44 is multiple (e.g., two or three), and the multiple bracket unlocking parts 44 are arranged circumferentially along the outer shell 12, with each bracket unlocking part 44 abutting against its corresponding first latching part 42. With this arrangement, the multiple sets of first latching structures 41 can more securely latch the sensor bracket 2 when in the first latching state.

[0142] The process of implanting sensor 310 into implanter 100 is as follows: Figure 3a As shown, the abutting end 11a of the inner shell 11 is placed against the implantation site 600, and an action is applied to the outer shell 12, causing the outer shell 12 to move relative to the inner shell 11 in a direction closer to the abutting end 11a (e.g., downward in the figure). The bracket unlocking part 44, driven by the outer shell 12, moves towards the abutting end 11a and presses the first elastic locking arm 421 of the first locking part 42. The first elastic locking arm 421 undergoes elastic deformation under pressure, causing the protrusion 424 to disengage from the second locking part 43. At this time, as... Figure 3d As shown, the first latching structure 41 is in the first unlocked state, and the first elastic element 31 is triggered and releases its elastic potential energy, as... Figure 3e As shown, under the action of the first elastic force of the first elastic member 31, the sensor bracket 2 moves along the first direction Z to the implantation position, the sensor 310 adheres to the epidermis of the implantation site 600, and the sensor implantation part 313 is inserted into the implantation site 600 under the action of the puncture needle 320. After the implantation of the sensor 310 is completed, as... Figure 3f As shown, the puncture needle 320 is withdrawn with the implanter 100, while the sensor 310 remains at the implantation site 600 to monitor the physiological information of the implantation site 600 in real time.

[0143] In some embodiments, such as Figure 3a As shown, the sensor bracket 2 has a first cavity 21, which has a first cavity wall 211 and a second cavity wall 212 arranged along a first direction Z, and a cavity sidewall 213 connecting the first cavity wall 211 and the second cavity wall 212. A filler 5 is provided inside the first cavity 21, which can move within the first cavity 21 under the action of inertial force and / or gravity, so that the filler 5 contacts the first cavity wall 211 or the second cavity wall 212. The receiving cavity 22 is used to house the sensor assembly 300. Figure 3a As shown, the first cavity wall 211 is close to the abutment end 11a, and the second cavity wall 212 is disposed opposite to the first cavity wall 211. It should be understood that the filler 5 can move within the first cavity 21 under the action of inertial force and / or gravity. This can be because the filler 5 moves within the first cavity 21 under the action of gravity, for example, when the implanter 100 changes from a horizontal to a vertical posture; or because the filler 5 moves within the first cavity 21 under the action of inertial force, for example, when the sensor bracket 2 moves from a stationary position towards the implantation position; or because the filler 5 moves within the first cavity 21 under the combined action of gravity and inertial force.

[0144] With this configuration, during the implantation of sensor 310 by implanter 100, when the first latching structure 41 switches to the first unlocking state, as follows: Figure 3d As shown, the sensor bracket 2, under the action of the first elastic force of the first elastic element 31, moves from a static state toward the implantation position (e.g., Figure 3d When moving downwards (as shown), the filler 5 contacts the second cavity wall 212 under the action of inertial force. At the instant of contact with the second cavity wall 212, the filler 5 will generate a first impact force on the second cavity wall 212. This first impact force can offset part of the first elastic force, thereby decelerating the sensor bracket 2 to control the moving speed of the sensor bracket 2 and prevent the sensor bracket 2 from moving too fast when it moves to the implantation position and being rebounded by the implantation site 600, causing aggravated oscillation; Figure 3e As shown, when the sensor bracket 2 moves to the implantation position, the movement of the sensor bracket 2 stops, and the filler 5 comes into contact with the first cavity wall 211 under the action of inertial force and gravity. At the moment of contact with the first cavity wall 211, the filler 5 will generate a second impact force on the first cavity wall 211. This second impact force can offset the elastic force generated by the release of the residual elastic potential energy of the first elastic element 31 and the rebound force of the implantation site 600 on the sensor bracket 2, thereby reducing the oscillation generated by the sensor bracket 2 and thus reducing the puncture damage caused by the puncture needle 320 to the implantation site 600.

[0145] In some embodiments, such as Figure 3a As shown, the filler 5 includes multiple filler bodies 50, each of which can move within the first cavity 21 under the action of inertial force and / or gravity, so that the filler 5 contacts the first cavity wall 211 or the second cavity wall 212. By providing multiple filler bodies 50, the multiple filler bodies 50 can be distributed to more positions in the first cavity 21. In this way, during the implantation of the sensor 310 by the implanter 100, the impact force generated by the filler 5 on the first cavity wall 211 or the second cavity wall 212 is more uniform, thereby better reducing the vibration generated by the sensor support 2, and thus reducing the puncture damage caused by the puncture needle 320 to the implantation site 600.

[0146] In some embodiments, such as Figure 3a As shown, the volume V1 of the filler 5 and the volume V2 of the first cavity 21 can satisfy the following condition: 0.3V2≤V1≤0.7V2. For example, V1 can be 0.3V2, 0.4V2, 0.5V2, 0.6V2, 0.7V2, etc. This setting can avoid the filler 5 volume V1 being too large or too small. If the filler 5 volume V1 is too large, the space for the filler 5 to move within the first cavity 21 is small. During the implantation of the sensor 310 by the implanter 100, it is not conducive to increasing the impact force generated by the filler 5 on the first cavity wall 211 or the second cavity wall 212, thus hindering the improvement of the vibration elimination effect on the sensor support 2. If the filler 5 volume V1 is too small, the mass of the filler 5 is small. During the implantation of the sensor 310 by the implanter 100, it is also not conducive to increasing the impact force generated by the filler 5 on the first cavity wall 211 or the second cavity wall 212, thus hindering the improvement of the vibration elimination effect on the sensor support 2.

[0147] By setting the volume V1 of the filler 5 to 0.3V2≤V1≤0.7V2, the filler 5 can be guaranteed to have sufficient mass and ample space for movement. During the implantation of the sensor 310 by the implanter 100, the filler 5 can generate a large impact force on the first cavity wall 211 or the second cavity wall 212, which is beneficial to improving the vibration elimination effect of the sensor support 2 and thus reducing the puncture damage caused by the puncture needle 320 to the implantation site 600.

[0148] Among them, such as Figure 3a As shown, when the filler 5 includes multiple fillers 50, the volume V1 of the filler 5 is the sum of the volumes of all fillers 50 in the first cavity 21.

[0149] In some embodiments, such as Figure 3aAs shown, the width d1 of the filler 50 and the width d2 of the first cavity 21 along the vertical direction X of the first direction Z satisfy: d1 ≥ 0.25 * d2. This setting avoids the filler 50 width d1 being too small. If the filler 50 width d1 is too small, the volume and mass of the filler 50 will be too small. During the implantation of the sensor 310 by the implanter 100, the movement direction of the filler 50 is easily uncontrollable, which is not conducive to improving the impact force generated by the filler 5 along the first direction Z on the first cavity wall 211 or the second cavity wall 212, thus hindering the improvement of the vibration elimination effect on the sensor support 2.

[0150] By setting the width d1 of the filler 50 to d1≥0.25*d2, it can be ensured that the filler 50 has sufficient volume and mass. During the implantation of the sensor 310 by the implanter 100, it is beneficial to control the movement of the filler 50 along the first direction Z, thereby improving the impact force generated by the filler 5 on the first cavity wall 211 or the second cavity wall 212 along the first direction Z. This, in turn, helps to improve the vibration elimination effect on the sensor support 2, thereby reducing the puncture damage caused by the puncture needle 320 to the implantation site 600.

[0151] It is important to understand that: such as Figure 3a As shown, the width d2 of the first cavity 21 specifically refers to the distance between the inner surfaces of the two opposing cavity sidewalls 213 of the first cavity 21 along the vertical X direction of the first direction Z.

[0152] In some embodiments, such as Figure 3a As shown, the filler 5 has multiple filling layers 51 along the first direction Z; along the vertical direction X of the first direction Z, each filling layer 51 has 2 to 5 filler bodies 50 arranged side by side. This arrangement avoids the filler body 50 having a width d1 that is too large or too small. If the width d1 of the filler body 50 is too large, the volume and mass of the filler body 50 will be too large, and during the implantation of the sensor 310 by the implanter 100, the movement amplitude of the filler body 50 under the action of inertial force will be small, which will weaken the impact force of the filler 5 on the first cavity wall 211 or the second cavity wall 212, thus hindering the improvement of the vibration elimination effect on the sensor support 2. If the width d1 of the filler body 50 is too small, during the implantation of the sensor 310 by the implanter 100, the movement direction of the filler body 50 will be easily out of control, which will hinder the improvement of the impact force generated by the filler 5 along the first direction Z on the first cavity wall 211 or the second cavity wall 212, thus hindering the improvement of the vibration elimination effect on the sensor support 2.

[0153] By having 2 to 5 fillers 50 arranged side by side in the vertical direction X along the first direction Z, the fillers 50 can be guaranteed to have sufficient volume and mass. During the implantation of the sensor 310 by the implanter 100, not only can the movement amplitude of the fillers 50 under the action of inertial force be increased, but it is also beneficial to control the movement of the fillers 50 along the first direction Z. This is beneficial to increase the impact force generated by the filler 5 on the first cavity wall 211 or the second cavity wall 212, and thus to improve the vibration elimination effect on the sensor support 2, so as to reduce the puncture damage caused by the puncture needle 320 to the implantation site 600.

[0154] In some embodiments, such as Figure 3a As shown, the filler 50 has a spherical structure. This design reduces the resistance of the filler 50 during movement, making it more mobile. During the implantation of the sensor 310 by the implanter 100, the filler 5 can more easily come into contact with the first cavity wall 211 or the second cavity wall 212, which helps to increase the impact force generated by the filler 5 on the first cavity wall 211 or the second cavity wall 212. This, in turn, helps to improve the vibration elimination effect on the sensor support 2, thereby reducing the puncture damage caused by the puncture needle 320 to the implantation site 600.

[0155] In addition to being spherical, the filler 50 can also be configured into other structures, such as block structures or rod structures, depending on the actual situation.

[0156] In some embodiments, such as Figure 3a As shown, the filler 50 is a solid structure. This design helps to improve the mass and rigidity of the filler 50. During the implantation of the sensor 310 by the implanter 100, it helps to increase the impact force generated by the filler 5 on the first cavity wall 211 or the second cavity wall 212, thereby improving the vibration elimination effect on the sensor support 2 and reducing the puncture damage caused by the puncture needle 320 to the implantation site 600.

[0157] In addition to being a solid structure, the infill 50 can also be set as a hollow structure depending on the actual situation.

[0158] The material of the filler 50 is not unique. In some embodiments, the material of the filler 50 is one of steel, iron, aluminum, or copper. This configuration allows the filler 50 to have lower elasticity and higher stiffness. During the implantation of the sensor 310 by the implanter 100, this helps to increase the impact force generated by the filler 5 on the first cavity wall 211 or the second cavity wall 212, thereby improving the vibration elimination effect on the sensor support 2 and reducing the puncture damage caused by the puncture needle 320 to the implantation site 600.

[0159] In other embodiments, the filler 50 is made of plastic with an elastic modulus of less than 100 MPa. This design allows the filler 50 to have lower elasticity and higher stiffness, which helps to increase the impact force generated by the filler 5 on the first cavity wall 211 or the second cavity wall 212 during the implantation of the sensor 310 by the implanter 100. This, in turn, helps to improve the vibration elimination effect on the sensor support 2, thereby reducing the puncture damage caused by the puncture needle 320 to the implantation site 600.

[0160] The filler 50 can be made of low-elasticity rubber, such as polyisobutylene rubber or nitrile rubber.

[0161] The form of filler 5 is not unique; in some embodiments, such as... Figure 3a As shown, the filler 5 can be a solid filler. With this configuration, the filler 5 is less likely to leak out of the first cavity 21, which helps to reduce the sealing requirements of the first cavity 21 and thus helps to reduce the cost of the implanter 100.

[0162] In other embodiments, the filler 5 may also be a liquid filler. Specifically, the filler 5 may be a liquid with low viscosity and good flowability, such as water or alcohol.

[0163] The location of the first cavity 21 in the sensor bracket 2 is not unique. In some embodiments, the first cavity 21 can be located near the outer end 2a of the bracket, as shown in the example below. Figure 3a As shown, along the first direction Z, the first cavity 21 extends to the outer end 2a of the stent and is spaced apart from the receiving cavity 22. With this configuration, when the sensor stent 2 moves to the implantation position, the first cavity wall 211 of the first cavity 21 (i.e., the cavity wall near the abutment end 11a) is closer to the implantation site 600. The impact force generated when the filler 5 contacts the first cavity wall 211 can better counteract the rebound force generated by the implantation site 600 on the sensor stent 2, thereby improving the vibration elimination effect of the sensor stent 2 and reducing the puncture damage caused by the puncture needle 320 to the implantation site 600.

[0164] Of course, it is not limited to this. In some other embodiments, the first cavity 21 may be located near the inner end 2b of the support, that is, along the first direction Z, the first cavity 21 extends to the inner end 2b of the support.

[0165] In some embodiments, such as Figure 3aAs shown, along the first direction Z, the size L1 of the first cavity 21 is less than half the size L2 of the sensor support 2. This setting avoids the first cavity 21 being too large. If the size L1 of the first cavity 21 is too large, during the implantation of the sensor 310 by the implanter 100, the filler 5 needs to move a longer distance under the action of inertial force before contacting the first cavity wall 211 or the second cavity wall 212. This reduces the impact force of the filler 5 on the first cavity wall 211 or the second cavity wall 212, thus hindering the improvement of the vibration elimination effect on the sensor support 2.

[0166] By setting the size L1 of the first cavity 21 to be less than half the size L2 of the sensor bracket 2, it is beneficial to increase the impact force of the filler 5 on the first cavity wall 211 or the second cavity wall 212 during the implantation of the sensor 310 by the implanter 100. This is beneficial to improve the vibration elimination effect on the sensor bracket 2, thereby reducing the puncture damage caused by the puncture needle 320 to the implantation site 600.

[0167] It is important to understand that: such as Figure 3a As shown, the dimension L1 of the first cavity 21 specifically refers to the distance between the inner surface of the first cavity wall 211 and the inner surface of the second cavity wall 212 along the first direction Z.

[0168] Figure 4 This is a schematic diagram of the implantation device 400 in the second embodiment of this application. Figure 4 The implantation device 400 shown is Figures 3a to 3f The main difference between the implantation device 400 shown is that the structure of the first snap-fit ​​structure 41 is different, as described below:

[0169] like Figure 4 As shown, the first snap-fit ​​structure 41 includes a first snap-fit ​​part 42 disposed on the inner shell 11 and a second snap-fit ​​part 43 disposed on the sensor bracket 2.

[0170] The second latching part 43 includes an elastic latching arm 431 and a protrusion structure 434. The elastic latching arm 431 includes a first latching arm section 432 connected to the sensor bracket 2 and a second latching arm section 433 connected to the first latching arm section 432. The protrusion structure 434 is disposed on the second latching arm section 433. The first latching arm section 432 is inclined relative to the first direction Z.

[0171] The first snap-fit ​​part 42 is a snap-fit ​​opening provided on the side wall of the inner shell 11. When the first snap-fit ​​structure 41 is in the first snap-fit ​​state, the protruding structure 434 extends into the first snap-fit ​​part 42 so that the first snap-fit ​​part 42 is snapped into the second snap-fit ​​part 43.

[0172] The outer shell 12 is slidably connected to the inner shell 11 along the first direction Z. The first locking structure 41 includes a bracket unlocking part 44, which is disposed on the inner wall of the outer shell 12 and abuts against the first locking arm section 432. When the outer shell 12 moves towards the abutting end 11a (e.g., ... Figure 4 When the bracket unlocking part 44 moves relative to the inner shell 11 in the downward direction, it presses the first locking arm section 432, causing the elastic locking arm 431 to undergo elastic deformation and drive the protruding structure 434 to disengage from the first locking part 42, thereby putting the first locking structure 41 in the first unlocked state.

[0173] The shape of the bracket unlocking part 44 is not unique; in some embodiments, such as... Figure 4 As shown, the bracket unlocking part 44 can be a block structure; however, it is not limited to this, the bracket unlocking part 44 can also be a columnar structure, a spherical structure, etc.

[0174] In some embodiments, such as Figure 4 As shown, the second latching part 43 is disposed at the inner end 2b of the sensor bracket 2, and the bracket unlocking part 44 is disposed at the closed end of the housing 12 (e.g., Figure 4 On the shell wall of the upper end of the outer shell 12 shown in the figure.

[0175] In some embodiments, such as Figure 4 As shown, multiple sets of the first snap-fit ​​structure 41 can be provided (e.g., two sets). With this configuration, multiple sets of the first snap-fit ​​structure 41 can securely snap the sensor bracket 2 when in the first snap-fit ​​state.

[0176] For details regarding the other structures of the implantation device 400 in this embodiment, please refer to [link / reference needed]. Figures 3a to 3f The structure of the implantation device 400 shown is configured as described here, and will not be described in detail here.

[0177] Figure 5 This is a schematic diagram of the implantation device 400 in the third embodiment of this application. Figure 5 The implantation device 400 shown is Figures 3a to 3f The main difference between the implantation device 400 shown is that the specific structure of the stent unlocking part 44 is different, as described below:

[0178] like Figure 5 As shown, the first snap-fit ​​structure 41 includes a first snap-fit ​​part 42 disposed on the inner shell 11 and a second snap-fit ​​part 43 disposed on the sensor bracket 2.

[0179] The first locking part 42 includes a first elastic locking arm 421 and a protrusion 424. The first elastic locking arm 421 includes a first arm segment 422 connected to the inner shell 11 and a second arm segment 423 connected to the first arm segment 422. The protrusion 424 is disposed on the second arm segment 423. The first arm segment 422 is inclined relative to the first direction Z.

[0180] The second snap-fit ​​part 43 is a snap-fit ​​opening provided on the side wall of the sensor bracket 2. When the first snap-fit ​​structure 41 is in the first snap-fit ​​state, the protrusion 424 extends into the second snap-fit ​​part 43 so that the first snap-fit ​​part 42 and the second snap-fit ​​part 43 are snapped together.

[0181] The inner shell 11 and the outer shell 12 are fixed relative to each other in the first direction Z. The inner shell 11 has a first wire hole 118 on its side wall and the outer shell 12 has a second wire hole 128 on its side wall. The second wire hole 128 is opposite to the first wire hole 118. The bracket unlocking part 44 includes a pull wire 441 and a pull ring 442. The pull wire 441 passes through the first wire hole 118 and the second wire hole 128. The first end of the pull wire 441 is connected to the first snap-fit ​​part 42 and the second end of the pull wire 441 is connected to the pull ring 442.

[0182] When the first locking structure 41 needs to be unlocked, the pull ring 442 is pulled. The pull ring 442 applies a pulling force to the first locking part 42 through the pull line 441, causing the first locking part 42 to undergo elastic deformation so as to disengage from the second locking part 43, thereby putting the first locking structure 41 into the first unlocked state.

[0183] In some embodiments, such as Figure 5 As shown, the first end of the pull cord 441 is connected to the second arm segment 423 of the first elastic locking arm 421. Since the second arm segment 423 is close to the protrusion 424, by connecting the first end of the pull cord 441 to the second arm segment 423, when the pull ring 442 is pulled, the first elastic locking arm 421 can undergo a large elastic deformation, making it easier for the protrusion 424 to disengage from the second locking part 43, thereby reducing the pulling force required to unlock the first locking structure 41.

[0184] In some embodiments, such as Figure 5 As shown, the first locking structure 41 is provided in multiple sets (e.g., two sets), and the multiple sets of the first locking structure 41 share a pull ring 442. By sharing a pull ring 442, multiple sets of the first locking structure 41 can be unlocked simultaneously when the pull ring 442 is pulled, thus facilitating the unlocking operation of the first locking structure 41.

[0185] For details regarding the other structures of the implantation device 400 in this embodiment, please refer to [link / reference needed]. Figures 3a to 3f The structure of the implantation device 400 shown is configured as described here, and will not be described in detail here.

[0186] Figure 6 This is a schematic diagram of the implantation device 400 in the fourth embodiment of this application. Figure 6 The implantation device 400 shown is Figures 3a to 3f The main difference between the implantation device 400 shown is that the specific structure of the stent unlocking part 44 is different, as described below:

[0187] like Figure 6 As shown, the first snap-fit ​​structure 41 includes a first snap-fit ​​part 42 disposed on the housing 1 and a second snap-fit ​​part 43 disposed on the sensor bracket 2.

[0188] The first locking part 42 includes a first elastic locking arm 421 and a protrusion 424. The first elastic locking arm 421 includes a first arm segment 422 connected to the inner shell 11 and a second arm segment 423 connected to the first arm segment 422. The protrusion 424 is disposed on the second arm segment 423. The first arm segment 422 is inclined relative to the first direction Z.

[0189] The second snap-fit ​​part 43 is a snap-fit ​​opening provided on the side wall of the sensor bracket 2. When the first snap-fit ​​structure 41 is in the first snap-fit ​​state, the protrusion 424 extends into the second snap-fit ​​part 43 so that the first snap-fit ​​part 42 and the second snap-fit ​​part 43 are snapped together.

[0190] The housing 1 has a contact end 11a and a setting end 1b. The inner cavity of the housing 1 extends through the contact end 11a. The setting end 1b is provided with a receiving groove 14. The bottom wall of the receiving groove 14 is provided with a clearance hole 15. The clearance hole 15 communicates with the inner cavity of the housing 1. The bracket unlocking part 44 includes an unlocking button 443 and a pressing part 444 connected to each other. The unlocking button 443 is slidably engaged with the receiving groove 14. The pressing part 444 passes through the clearance hole 15, and a portion of the pressing part 444 extends into the inner cavity of the housing 1 and abuts against the first arm segment 422 of the first elastic locking arm 421.

[0191] When the first locking structure 41 needs to be unlocked, press the unlock button 443. The squeezing part 444 squeezes the first arm segment 422, causing the first elastic locking arm 421 to undergo elastic deformation and drive the protrusion 424 to disengage from the second locking part 43, thereby putting the first locking structure 41 into the first unlocked state.

[0192] In some embodiments, such as Figure 6 As shown, the extrusion section 444 has a columnar structure; however, it is not limited to this, the extrusion section 444 can also have a spherical structure, a block structure, etc.

[0193] In some embodiments, such as Figure 6As shown, multiple (e.g., two) first latching parts 42 and two latching parts 43 are provided, and multiple (e.g., two) squeezing parts 444 are provided accordingly. Each squeezing part 444 is provided on the same unlocking button 443, and each squeezing part 444 abuts against the first elastic latching arm 421 of the corresponding first latching part 42.

[0194] For details regarding the other structures of the implantation device 400 in this embodiment, please refer to [link / reference needed]. Figures 3a to 3f The structure of the implantation device 400 shown is configured as described here, and will not be described in detail here.

[0195] Depend on Figures 4 to 6 As illustrated in the examples, those skilled in the art can configure the structure of the implantation device as needed. The specific structures of the implantation device 400 in the various embodiments herein are merely examples, and the embodiments of this application are not limited thereto. Those skilled in the art can configure a cavity for accommodating the filler 5 according to the specific structure of the implantation device. During sensor implantation, the "dead hammer effect" is utilized to reduce the vibration caused by the rebound of the sensor support at the implantation site, thereby reducing puncture damage to the implantation site. As mentioned above, the first cavity is not limited to the examples in the embodiments of this application. For example, the position and volume of the first cavity can be configured as needed. The filler in the first cavity is also not limited to the examples in the embodiments of this application. For example, the shape, volume, material, etc. of the filler can be configured as needed.

[0196] Figure 7a This is Figure 1, showing the state of the implantation device 400 in the fifth embodiment of this application during the implantation process. Figure 7b This describes the state of the implantation device 400 in the fifth embodiment of this application during the implantation process. Figure 2 ; Figure 7c Figure 3 shows the state of the implantation device 400 in the fifth embodiment of this application during the implantation process. Figure 7d This is a partial enlarged view of the second snap-fit ​​structure 45 of the implantation device 400 in the fifth embodiment of this application. Figure 7e This describes the state of the implantation device 400 in the fifth embodiment of this application during the implantation process. Figure 4 , Figure 7f This describes the state of the implantation device 400 in the fifth embodiment of this application during the implantation process. Figure 5 .

[0197] Figures 7a to 7f The implantation device 400 shown is Figures 3a to 3f The main difference of the implantation device 400 shown is: (1) Figures 7a to 7f The implantation device 400 shown is equipped with a needle-drawing mechanism including a needle-drawing seat 6, a second locking structure 45, and a second elastic element 32. The needle-drawing mechanism can retract the puncture needle 320 into the inner shell 11; (2) The shape of the first cavity 21 is different. Figures 7a to 7f The first cavity 21 of the implantation device 400 shown is an annular cavity, as described below:

[0198] In some embodiments, such as Figure 7a As shown, the implanter 100 also includes a needle extraction seat 6, a second elastic element 32, and a second snap-fit ​​structure 45.

[0199] The sensor holder 2 also has a second cavity 23, which communicates with the receiving cavity 22 and is spaced apart from the first cavity 21; the needle extraction seat 6 is at least partially disposed in the second cavity 23 and is used to connect with the puncture needle 320, and the needle extraction seat 6 can be positioned in a second initial position (e.g., along the first direction Z). Figure 7a , Figure 7b , Figure 7c (as shown in the image) and needle withdrawal position (e.g.) Figure 7e The needle holder 6 moves relative to the sensor bracket 2 between the positions shown, and when it is in the needle-pulling position, it is farther away from the outer end 2a of the bracket than when it is in the second initial position.

[0200] The second elastic element 32 is used to apply a second elastic force to the needle holder 6.

[0201] The second latching structure 45 includes a needle holder latching part 46 disposed on the needle extraction seat 6 and a bracket latching part 47 disposed on the sensor bracket 2. The second latching structure 45 has a second latching state and a second unlocking state; Figure 7a , Figure 7b as well as Figure 7d As shown in (a), when the second locking structure 45 is in the second locking state, the needle seat locking part 46 engages with the bracket locking part 47, and the needle drawer 6 is locked in the second initial position; Figure 7c and Figure 7d As shown in (b), when the second locking structure 45 is in the second unlocked state, the needle seat locking part 46 separates from the bracket locking part 47, and the needle drawer 6 moves to the needle drawer position under the action of the second elastic force.

[0202] In this embodiment, by setting up a needle-pulling mechanism such as a needle-pulling seat 6, a second snap-fit ​​structure 45, and a second elastic element 32, the puncture needle 320 can be retracted back into the housing 1 after the sensor 310 is implanted. This increases the safety of the implantation device 400 and prevents the protruding puncture needle 320 from scratching other parts of the user during the retraction of the implanter 100.

[0203] In some embodiments, such as Figure 7aAs shown, the needle holder locking part 46 includes an elastic arm 461 connected to the needle drawer 6, and a locking protrusion 462 provided on the elastic arm 461. The bracket locking part 47 is provided with a locking through hole 471, which is opposite to the side wall of the inner shell 11.

[0204] like Figure 7a , Figure 7b as well as Figure 7d As shown in (a), when the second snap-fit ​​structure 45 is in the second snap-fit ​​state, the snap-fit ​​protrusion 462 extends into the snap-fit ​​through hole 471 so that the pin seat snap-fit ​​part 46 snaps into the bracket snap-fit ​​part 47.

[0205] With this configuration, since the elastic arm 461 of the pin seat latching part 46 is elastic, when unlocking, only a certain force needs to be applied to the elastic arm 461 towards the inside of the sensor bracket 2 to allow the latching protrusion 462 to disengage from the latching through hole 471. The unlocking method is relatively simple and direct, which simplifies the setting of the unlocking component and eliminates the need for a complex unlocking mechanism.

[0206] In some embodiments, the second latching structure 45 can automatically unlock when the sensor holder 2 moves to the implantation position, as described below: Figure 7a , Figure 7b as well as Figure 7c As shown, the second snap-fit ​​structure 45 includes a pin seat unlocking part 48, which is disposed on the side wall of the inner shell 11. The bracket snap-fit ​​part 47 is provided with a sliding groove 472, which extends along the first direction Z and communicates with the snap-fit ​​through hole 471. The pin seat unlocking part 48 and the sliding groove 472 are slidably engaged.

[0207] like Figure 7c and Figure 7d As shown in (b), when the sensor bracket 2 moves to the implantation position, the needle seat unlocking part 48 can slide relative to the slide groove 472 to the position of the snap-fit ​​hole 471 and squeeze the snap-fit ​​protrusion 462, so that the snap-fit ​​protrusion 462 disengages from the snap-fit ​​hole 471, thereby putting the second snap-fit ​​structure 45 into the second unlocked state.

[0208] With the needle seat unlocking part 48 configured as described above, when the sensor bracket 2 moves to the implantation position, the needle seat locking part 46 can disengage from the bracket locking part 47 under the pressure of the needle seat unlocking part 48, thereby unlocking the second locking structure 45. The unlocking of the second locking structure 45 is performed automatically during the sensor 310 implantation process without manual operation, which makes the operation of implanting the sensor 310 by the implanter 100 more convenient, thereby improving the efficiency of implanting the sensor 310 by the implanter 100.

[0209] The bracket latching part 47 is not configured in a unique way; in some embodiments, such as... Figure 7a As shown, the bracket latching portion 47 can be part of the side wall of the sensor bracket 2. In other embodiments, the bracket latching portion 47 has a sheet-like structure and is disposed in a receiving groove opened on the side wall of the sensor bracket 2.

[0210] In some embodiments, such as Figure 7d As shown, the end of the pin seat unlocking part 48 that is away from the abutment end 11a (e.g.) Figure 7d A first guide slope 481 is provided at the upper end shown. The first guide slope 481 is inclined relative to the first direction Z and is used to contact the snap-fit ​​protrusion 462.

[0211] With this configuration, when the needle seat unlocking part 48 moves to the position of the locking through hole 471, the first guide slope 481 can contact the locking protrusion 462 and guide the locking protrusion 462, so that the locking protrusion 462 gradually disengages from the locking through hole 471 under the guidance of the first guide slope 481. This makes it easier for the locking protrusion 462 to disengage from the locking through hole 471 under the pressure of the needle seat unlocking part 48, thereby making the unlocking of the second locking structure 45 more stable and smooth.

[0212] In some embodiments, such as Figure 7a As shown, the second snap-fit ​​structure 45 is provided in multiple sets (e.g., two sets). With this configuration, multiple sets of second snap-fit ​​structures 45 can securely engage the pin drawer 6 when in the second snap-fit ​​state.

[0213] In some embodiments, the implantation of sensor 310 by implanter 100 is performed as follows:

[0214] like Figure 7a As shown, the abutting end 11a of the inner shell 11 is placed against the implantation site 600, and an action is applied to the outer shell 12, causing the outer shell 12 to move relative to the inner shell 11 in a direction closer to the abutting end 11a (e.g., downward in the figure). The bracket unlocking part 44, driven by the outer shell 12, moves towards the abutting end 11a and presses the first elastic locking arm 421 of the first locking part 42. The first elastic locking arm 421 undergoes elastic deformation under pressure, causing the protrusion 424 to disengage from the second locking part 43. At this time, as... Figure 7b As shown, the first latching structure 41 is in the first unlocked state, and the first elastic element 31 is triggered and releases its elastic potential energy.

[0215] like Figure 7cAs shown, under the action of the first elastic force of the first elastic member 31, the sensor bracket 2 moves along the first direction Z to the implantation position, the sensor 310 is attached to the epidermis of the implantation site 600, and the sensor implantation part 313 is inserted into the implantation site 600 under the action of the puncture needle 320. At the same time, under the pressure of the needle seat unlocking part 48, the locking protrusion 462 disengages from the locking through hole 471, so that the second locking structure 45 is in the second unlocked state, the second elastic member 32 is triggered and its elastic potential energy is released.

[0216] like Figure 7e As shown, under the action of the second elastic force of the second elastic member 32, the needle extraction seat 6 moves to the needle extraction position along the first direction Z, the puncture needle 320 retracts into the inner shell 11, and separates from the sensor implantation part 313 inserted into the implantation site 600.

[0217] like Figure 7f As shown, after the sensor 310 is implanted, the puncture needle 320 is withdrawn with the implanter 100, and the sensor 310 remains at the implantation site 600 to monitor the physiological information of the implantation site 600 in real time.

[0218] In some embodiments, such as Figure 7a As shown, the receiving cavity 22 includes a first receiving cavity 221 and a second receiving cavity 222 that are connected to each other. The first receiving cavity 221 is located at the outer end 2a of the support and is used to house the sensor 310. The second receiving cavity 222 is located on the side of the first receiving cavity 221 away from the abutment end 11a and is used to allow the end of the puncture needle 320 away from the puncture end 321 to extend into it. The first cavity 21 is an annular cavity and is arranged around the second receiving cavity 222. The first cavity 21 is spaced apart from both the first receiving cavity 221 and the second receiving cavity 222.

[0219] By setting the first cavity 21 as an annular cavity and surrounding the second receiving cavity 222, the space around the second receiving cavity 222 can be fully utilized, so that the dimensions of the first cavity 21 and the second receiving cavity 222 overlap in the first direction Z, thereby avoiding the sensor bracket 2 from being too large in the first direction Z, which is beneficial to controlling the volume of the implanter 100.

[0220] Of course, the first cavity 21 is not limited to an annular cavity. Multiple first cavities 21 can be provided, and multiple first cavities 21 are arranged along the circumference of the sensor bracket 2 and surround the second receiving cavity 222.

[0221] In some embodiments, such as Figure 7a and Figure 7e As shown, the receiving cavity 22 also includes a connecting hole 223, which is disposed between the first receiving cavity 221 and the second receiving cavity 222 and connects the first receiving cavity 221 and the second receiving cavity 222.

[0222] In some embodiments, the pin drawer 6 can have the following structure, such as Figure 7a As shown, the needle holder 6 includes a seat body 61 and a puncture needle connecting part 62 connected to each other. The seat body 61 is disposed in the second cavity 23, and the needle holder locking part 46 is disposed on the seat body 61. The puncture needle connecting part 62 extends into the second receiving cavity 222 and is detachably connected to the puncture needle 320.

[0223] The puncture needle connection part 62 can be detachably connected to the puncture needle 320 through connection methods such as snap-fit, screw-fit, plug-in, and adhesive.

[0224] The type of the second elastic element 32 is not unique; in some embodiments, such as... Figure 7a As shown, the second elastic element 32 can be a spring. One end of the second elastic element 32 is connected to the needle holder 6, and the other end of the second elastic element 32 is connected to the cavity wall of the second receiving cavity 222.

[0225] Among them, such as Figure 7a As shown, the second elastic member 32 can be sleeved on the outside of the puncture needle connection part 62. This arrangement makes the structure of the second elastic member 32 and the puncture needle connection part 62 more compact, which helps to reduce the space occupied in the second receiving cavity 222.

[0226] The second elastic element 32 is not limited to a spring. In other embodiments, the second elastic element 32 can also be a sheet, which can be V-shaped, W-shaped, wavy, etc. One end of the sheet is connected to the needle-drawing seat 6, and the other end of the sheet is connected to the cavity wall of the second receiving cavity 222.

[0227] In some embodiments, such as Figure 7a As shown, the filling material 5 in the first cavity 21 includes a plurality of filling bodies 50. Each filling body 50 can move within the first cavity 21 under the action of inertial force and / or gravity, so that the filling material 5 comes into contact with the first cavity wall 211 or the second cavity wall 212.

[0228] In some embodiments, such as Figure 7a As shown, the volume V1 of the filler 5 and the volume V2 of the first cavity 21 satisfy the following condition: 0.3V2≤V1≤0.7V2.

[0229] In some embodiments, such as Figure 7aAs shown, along the vertical X direction of the first direction Z, the width d1 of the filler 50 and the width d2 of the first cavity 21 satisfy: d1 ≥ 0.25d2. It should be understood that when the first cavity 21 is an annular cavity, the cavity sidewall 213 of the first cavity 21 includes an outer cavity sidewall 2131 and an inner cavity sidewall 2132. The width d2 of the first cavity 21 is the distance between the inner surface of the outer cavity sidewall 2131 and the inner surface of the inner cavity sidewall 2132 (i.e., the surface located within the first cavity 21) along the vertical X direction of the first direction Z. For example... Figure 7c As shown.

[0230] In some embodiments, such as Figure 7a As shown, the filler 5 has multiple filler layers 51 along the first direction Z; each filler layer 51 has 2 to 5 filler bodies 50 arranged side by side along the vertical direction X of the first direction Z, for example... Figure 7a As shown, each filler layer 51 has four fillers 50 arranged side by side.

[0231] In some embodiments, such as Figure 7a As shown, the filler 50 has a spherical structure.

[0232] In some embodiments, such as Figure 7a As shown, the infill 50 is a solid structure.

[0233] In some embodiments, such as Figure 7a As shown, filler 5 is a solid filler. In other embodiments, filler 5 may also be a liquid filler.

[0234] In some embodiments, the filler 50 is made of one of steel, iron, aluminum, and copper, such as steel. In other embodiments, the filler 50 is made of plastic with an elastic modulus of less than 100 MPa.

[0235] In some embodiments, such as Figure 7a As shown, along the first direction Z, the first cavity 21 extends to the outer end 2a of the support and is spaced apart from the receiving cavity 22.

[0236] In some embodiments, such as Figure 7a As shown, along the first direction Z, the size L1 of the first cavity 21 is less than half the size L2 of the sensor bracket 2.

[0237] For details regarding the other structures of the implantation device 400 in this embodiment, please refer to [link / reference needed]. Figures 3a to 3f The structure of the implantation device 400 shown is configured as described here, and will not be described in detail here.

[0238] Figure 8 This is a schematic diagram of the implantation device 400 in the sixth embodiment of this application. Figure 6 The implantation device 400 shown is Figures 7a to 7f The main differences between the implantation devices 400 shown are: (1) the structure of the stent unlocking part 44 is different; (2) the structure of the needle hub unlocking part 48 is different; as detailed below:

[0239] In some embodiments, such as Figure 8 As shown, the first snap-fit ​​structure 41 includes a first snap-fit ​​part 42 disposed on the housing 1 and a second snap-fit ​​part 43 disposed on the sensor bracket 2.

[0240] The first locking part 42 includes a first elastic locking arm 421 and a protrusion 424. The first elastic locking arm 421 includes a first arm segment 422 connected to the inner shell 11 and a second arm segment 423 connected to the first arm segment 422. The protrusion 424 is disposed on the second arm segment 423. The first arm segment 422 is inclined relative to the first direction Z.

[0241] The second snap-fit ​​part 43 is a snap-fit ​​opening provided on the side wall of the sensor bracket 2. When the first snap-fit ​​structure 41 is in the first snap-fit ​​state, the protrusion 424 extends into the second snap-fit ​​part 43 so that the first snap-fit ​​part 42 and the second snap-fit ​​part 43 are snapped together.

[0242] The housing 1 has a contact end 11a and a setting end 1b. The inner cavity of the housing 1 extends through the contact end 11a. The setting end 1b is provided with a receiving groove 14. The bottom wall of the receiving groove 14 is provided with a clearance hole 15. The clearance hole 15 communicates with the inner cavity of the housing 1. The bracket unlocking part 44 includes an unlocking button 443 and a pressing part 444 connected to each other. The unlocking button 443 is slidably engaged with the receiving groove 14. The pressing part 444 passes through the clearance hole 15, and a portion of the pressing part 444 extends into the inner cavity of the housing 1 and abuts against the first arm segment 422 of the first elastic locking arm 421.

[0243] When the first locking structure 41 needs to be unlocked, press the unlock button 443. The squeezing part 444 squeezes the first arm segment 422, causing the first elastic locking arm 421 to undergo elastic deformation and drive the protrusion 424 to disengage from the second locking part 43, thereby putting the first locking structure 41 into the first unlocked state.

[0244] In some embodiments, such as Figure 8 As shown, the extrusion section 444 has a columnar structure; however, it is not limited to this, the extrusion section 444 can also have a spherical structure, a block structure, etc.

[0245] In some embodiments, such as Figure 8As shown, multiple (e.g., two) first latching parts 42 and two latching parts 43 are provided, and multiple (e.g., two) squeezing parts 444 are provided accordingly. Each squeezing part 444 is provided on the same unlocking button 443, and each squeezing part 444 abuts against the first elastic latching arm 421 of the corresponding first latching part 42.

[0246] In some embodiments, such as Figure 8 As shown, the second snap-fit ​​structure 45 includes a needle holder snap-fit ​​part 46 disposed on the needle holder 6 and a bracket snap-fit ​​part 47 disposed on the sensor bracket 2.

[0247] Among them, such as Figure 8 As shown, the needle holder locking part 46 includes an elastic arm 461 connected to the needle drawer 6, and a locking protrusion 462 provided on the elastic arm 461. The bracket locking part 47 is provided with a locking through hole 471, which is opposite to the side wall of the inner shell 11. When the second locking structure 45 is in the second locking state, the locking protrusion 462 extends into the locking through hole 471, so that the needle holder locking part 46 and the bracket locking part 47 are locked together.

[0248] A button receiving groove 16 is provided on the outer surface of the side wall of the housing 1. A through hole 17 is provided on the groove wall of the button receiving groove 16, and the through hole 17 communicates with the inner cavity of the housing 1. The pin seat unlocking part 48 includes a button 483 and a pressing rod 484 connected to each other. The button 483 is disposed in the button receiving groove 16, and the pressing rod 484 is slidably engaged with the through hole 17.

[0249] When the sensor bracket 2 is moved to the implantation position, the through hole 17 is opposite to the snap-fit ​​through hole 471. Pressing the button 483 will cause the squeezing rod 484 to squeeze the snap-fit ​​protrusion 462, causing the snap-fit ​​protrusion 462 to disengage from the snap-fit ​​through hole 471, thereby putting the second snap-fit ​​structure 45 into the second unlocked state.

[0250] In some embodiments, such as Figure 8 As shown, the second snap-fit ​​structure 45 is provided with multiple sets (e.g., two sets).

[0251] For details regarding the other structures of the implantation device 400 in this embodiment, please refer to [link / reference needed]. Figures 7a to 7f The structure of the implantation device 400 shown is configured as described here, and will not be described in detail here.

[0252] The following section will use specific 3D images to illustrate... Figures 7a to 7f The shape, structure, and connection relationship of each component in the implantation device 400 shown are explained in detail.

[0253] Figure 9a This is a schematic diagram of the implantation device 400 in the seventh embodiment of this application. Figure 9b for Figure 9aAn exploded view of the implantation device 400 shown. Figure 10a for Figure 9a The BB cross-sectional view of the implantation device 400 shown (sensor bracket 2 is in the first initial position) is shown. Figure 10b for Figure 10a The sensor support 2 of the implantation device 400 is shown in a state diagram when it moves to the implantation position.

[0254] like Figure 9a and Figure 10a As shown, the implantation device 500 includes an implanter 100 and a sensor assembly 300. The implanter 100 includes a housing 1, a sensor support 2, a first elastic element 31, a first snap-fit ​​structure 41, a needle extraction seat 6, a second elastic element 32, and a second snap-fit ​​structure 45.

[0255] like Figure 9a , Figure 9b and Figure 10a As shown, the shell 1 includes an inner shell 11 and an outer shell 12. The inner shell 11 has an inner end 11b and an abutment end 11a. The inner end 11b is located inside the outer shell 12, and the abutment end 11a extends out of the outer shell 12 and is used to abut against the implantation site 600 of the organism. The inner cavity of the inner shell 11 extends through at least the abutment end 11a.

[0256] Among them, such as Figure 9a and Figure 9b As shown, the outer shell 12 can be a sleeve-like structure with one end open and the other end closed (i.e., the outer shell 12 has an open end and a closed end), and the inner shell 11 can be a sleeve-like structure with openings at both ends. The abutting end 11a of the inner shell 11 extends from the open end of the outer shell 12 (e.g., Figure 9b The lower end of the outer shell 12 shown extends out. Of course, the structure of the outer shell 12 and the inner shell 11 is not limited to this, and the outer shell 12 and the inner shell 11 can also be set to other structures according to the actual situation.

[0257] like Figure 9b and Figure 10a As shown, the sensor bracket 2 is disposed in the inner cavity of the inner shell 11. The end of the sensor bracket 2 near the inner end 11b of the shell is the inner end 2b of the bracket, and the end of the sensor bracket 2 near the abutment end 11a is the outer end 2a of the bracket. A receiving cavity 22 is provided at the outer end 2a of the bracket. The receiving cavity 22 is used to install the sensor assembly 300. The sensor assembly 300 includes a sensor 310 and a puncture needle 320 for implanting the sensor 310 into the implantation site 600.

[0258] The sensor bracket 2 can be positioned at the first initial position along the first direction Z (e.g., Figure 10a The location of the sensor bracket 2 shown in the figure) and the implantation location (e.g. Figure 10b The sensor bracket 2 shown in the diagram can move relative to the inner shell 11, as shown in the diagram. Figure 10aand Figure 10b As shown, the sensor holder 2 is closer to the abutment end 11a when it is in the implantation position than when it is in the first initial position.

[0259] Among them, such as Figure 9b and Figure 10a As shown, the sensor bracket 2 can be a sleeve-like structure, meaning that the inner end 2b of the sensor bracket 2 has an opening. Of course, it is not limited to this, and the sensor bracket 2 can also be configured with other structures according to the actual situation.

[0260] like Figure 9b and Figure 10a As shown, the first elastic element 31 is used to apply a first elastic force to the sensor bracket 2.

[0261] like Figure 9b and Figure 10a As shown, the first latching structure 41 includes a first latching portion 42 disposed on the inner shell 11 and a second latching portion 43 disposed on the sensor bracket 2. The first latching structure 41 has a first latching state and a first unlocking state, as shown in the figure. Figure 10a As shown, when the first latching structure 41 is in the first latching state, the first latching part 42 and the second latching part 43 are latched together, and the sensor bracket 2 is locked in the first initial position; as Figure 10b As shown, when the first locking structure 41 is in the first unlocked state, the first locking part 42 and the second locking part 43 are separated, and the sensor bracket 2 moves to the implantation position under the force of the first elastic member 31.

[0262] like Figure 9b and Figure 10a As shown, the sensor bracket 2 has a first cavity 21, which has a first cavity wall 211 and a second cavity wall 212 arranged along the first direction Z. The first cavity 21 is filled with a filler 5, which can move within the first cavity 21 under the action of inertial force and / or gravity, so that the filler 5 comes into contact with the first cavity wall 211 or the second cavity wall 212.

[0263] In some embodiments, in the first latching structure 41, the first latching portion 42 and the second latching portion 43 can have the following structures: such as Figure 9b and Figure 10aAs shown, the first locking portion 42 includes a first elastic locking arm 421 and a protrusion 424. The first elastic locking arm 421 includes a first arm segment 422 connected to the inner shell 11 and a second arm segment 423 connected to the first arm segment 422. The protrusion 424 is disposed on the second arm segment 423, and the first arm segment 422 is inclined relative to the first direction Z. The second locking portion 43 is a locking opening disposed on the side wall of the sensor bracket 2. When the first locking structure 41 is in the first locking state, the protrusion 424 extends into the second locking portion 43 so that the first locking portion 42 and the second locking portion 43 are locked together.

[0264] In some embodiments, the first latching structure 41 can be unlocked by moving the housing 12, specifically as follows: Figure 10a and Figure 10b As shown, the outer shell 12 is slidably connected to the inner shell 11 along the first direction Z. The first snap-fit ​​structure 41 includes a bracket unlocking part 44, which is disposed on the inner wall of the outer shell 12 and abuts against the first arm segment 422. When the outer shell 12 moves towards the abutting end 11a (e.g., ... Figure 10a When the bracket unlocking part 44 moves relative to the inner shell 11 in the downward direction, it presses the first arm segment 422, causing the first elastic locking arm 421 to undergo elastic deformation and drive the protrusion 424 to disengage from the second locking part 43, thereby putting the first locking structure 41 in the first unlocked state.

[0265] In some embodiments, such as Figure 9b and Figure 10a As shown, the second arm segment 423 of the first elastic locking arm 421 is located on the outer side of the side wall of the sensor bracket 2, along the first direction Z and pointing from the inner end 11b of the inner shell 11 to the abutment end 11a (e.g. Figure 10a (In the vertically downward direction), the distance from the first arm segment 422 to the central axis 110 of the inner shell 11 gradually decreases.

[0266] When the outer casing 12 moves towards the abutment end 11a (for example) Figure 10a When the bracket unlocking part 44 moves relative to the inner shell 11 in the downward direction, it presses against the first arm segment 422, as... Figure 10b As shown, under the pressure of the bracket unlocking part 44, the first elastic locking arm 421 opens to the outside of the side wall of the sensor bracket 2, and drives the protrusion 424 to disengage from the second locking part 43, thereby putting the first locking structure 41 into the first unlocked state.

[0267] By placing the second arm segment 423 of the first elastic clamping arm 421 on the outer side of the side wall of the sensor bracket 2, the first elastic clamping arm 421 can be prevented from occupying the internal space of the sensor bracket 2, thereby preventing the first elastic clamping arm 421 from interfering with the internal structure of the sensor bracket 2.

[0268] In some embodiments, such as Figure 10a , Figure 10b and Figure 11 As shown, Figure 11 for Figure 9b The diagram shows the structure of the outer shell 12 in the implantable device 400. The stent unlocking part 44 has an abutment slope 441, which is inclined relative to the first direction Z and contacts the first arm segment 422. By providing the abutment slope 441 on the stent unlocking part 44, the contact area between the stent unlocking part 44 and the first elastic locking arm 421 can be increased, thereby preventing damage to the first elastic locking arm 421 caused by the sharp edges of the stent unlocking part 44.

[0269] The shape of the bracket unlocking part 44 is not unique; in some embodiments, such as... Figure 11 As shown, the bracket unlocking part 44 is a block structure and is disposed on the shell wall of the closed end of the outer shell 12. Of course, the bracket unlocking part 44 is not limited to a block structure; it can also be a columnar structure, a spherical structure, etc., and no specific limitation is made here.

[0270] In some embodiments, such as Figure 10a , Figure 12 and Figure 13 As shown, Figure 12 for Figure 9b The diagram shown is a structural schematic of the inner shell 11 of the implantation device 400 from one viewpoint. Figure 13 for Figure 9b The diagram shows the structure of the inner shell 11 in the implantation device 400 from another perspective. The first latching part 42 is disposed at the inner end 11b of the inner shell 11. This arrangement allows the first latching part 42 to be close to the closed end of the outer shell 12, that is, close to the stent unlocking part 44, thereby facilitating the contact between the stent unlocking part 44 and the first latching part 42.

[0271] In some embodiments, such as Figure 9b and Figure 10a As shown, the first latching structure 41 is provided in multiple sets (e.g., two sets), that is, the number of first latching parts 42 is multiple (e.g., two), and they are arranged along the circumference of the inner shell 11; the number of second latching parts 43 is multiple (e.g., two), and they are arranged along the circumference of the sensor bracket 2, and each second latching part 43 is used to latch with the corresponding first latching part 42; the number of bracket unlocking parts 44 is multiple (e.g., two), and they are arranged along the circumference of the outer shell 12, and each bracket unlocking part 44 abuts against the corresponding first latching part 42.

[0272] Of course, in other embodiments, a set of first snap-fit ​​structures 41 may also be provided.

[0273] To reduce the space occupied by the first snap-fit ​​portion 42 on the inner and outer sides of the inner shell 11, in some embodiments, such as Figure 12 and Figure 13 As shown, the inner shell 11 has a retaining arm receiving groove 112 on its side wall, which extends along the first direction Z. The first elastic retaining arm 421 of the first retaining part 42 is disposed in the retaining arm receiving groove 112. This arrangement makes the structure of the inner shell 11 and the first retaining part 42 more compact, reducing the space occupied by the first retaining part 42 on the inner and outer sides of the inner shell 11. The space saved on the inner and outer sides of the inner shell 11 can then be used to arrange other structures, thereby facilitating the optimized layout of the inner and outer structures of the inner shell 11.

[0274] Among them, such as Figure 10a and Figure 12 As shown, the end of the first elastic locking arm 421 near the inner end 11b of the shell is connected to the side wall of the inner shell 11.

[0275] In some embodiments, such as Figure 12 As shown, the first snap-fit ​​part 42 is an integral structure with the side wall of the inner shell 11; of course, it is not limited to this, the first snap-fit ​​part 42 can also be separately set from the side wall of the inner shell 11.

[0276] In some embodiments, such as Figure 11 and Figure 12 As shown, the inner shell 11 has an outer shell guide portion 113 on its side wall. The outer shell guide portion 113 includes a first guide portion 1131 and a second guide portion 1132. Along the width direction of the arm receiving groove 112, the first guide portion 1131 and the second guide portion 1132 are located at opposite sides of the arm receiving groove 112. The outer shell 12 has a sliding guide groove 121 on its side wall. The sliding guide groove 121 extends along the first direction Z. The outer shell guide portion 113 slides with the sliding guide groove 121 so that the outer shell 12 slides with the inner shell 11 along the first direction Z.

[0277] With this configuration, the outer shell guide portion 113 and the sliding guide groove 121 form a sliding guide structure, which can prevent the outer shell 12 from shaking or rotating relative to the inner shell 11, thereby allowing the outer shell 12 to move more smoothly relative to the inner shell 11 along the first direction Z. Simultaneously, since the first guide portion 1131 and the second guide portion 1132 are located at opposite edges of the arm receiving groove 112, the outer shell guide portion 113 avoids occupying space on other parts of the side wall of the inner shell 11, making the structure on the side wall of the inner shell 11 more compact, which in turn facilitates the optimized arrangement of the structure on the inner shell 11.

[0278] Among them, such as Figure 12 As shown, the first guide portion 1131 and the second guide portion 1132 are guide ribs, which extend along the first direction Z.

[0279] In some embodiments, such as Figure 10b , Figure 11 and Figure 12 As shown, there are multiple sliding guide grooves 121 (e.g., two) arranged along the circumference of the outer shell 12; there are multiple outer shell guide portions 113 (e.g., two) arranged along the circumference of the inner shell 11; each outer shell guide portion 113 includes a first guide portion 1131 and a second guide portion 1132, and each outer shell guide portion 113 is slidably engaged with the corresponding sliding guide groove 121.

[0280] Of course, in other embodiments, the number of housing guide portion 113 and sliding guide groove 121 may also be one each.

[0281] In some embodiments, such as Figure 11 and Figure 12 As shown, the outer shell guide portion 113 can be integrally formed with the side wall of the inner shell 12; however, it is not limited to this, the outer shell guide portion 113 can also be separately formed from the side wall of the inner shell 12.

[0282] In some embodiments, such as Figure 12 , Figure 13 and Figure 14 As shown, Figure 14 for Figure 9b This is a schematic diagram of the axial limiting structure between the inner shell 11 and the outer shell 12 of the implantation device 400. The outer shell 12 is connected to the inner shell 11 through the axial limiting structure. The axial limiting structure includes an axial limiting arm 114 disposed on the inner shell 11 and a limiting annular groove 123 disposed on the side wall of the outer shell 12. The limiting annular groove 123 is disposed on the inner surface of the side wall of the outer shell 12 and surrounds the central axis of the outer shell 12. The axial limiting arm 114 extends along the first direction Z, and the engaging end of the axial limiting arm 114 extends into the limiting groove 123.

[0283] When the outer shell 12 moves relative to the inner shell 11 along the first direction Z, the axial limiting structure can limit the range of movement of the axial limiting arm 114 along the first direction Z, thereby limiting the range of movement of the outer shell 12 relative to the inner shell 11 along the first direction Z, so as to prevent the outer shell 12 from moving away from the inner shell 11.

[0284] Among them, such as Figure 14 As shown, the limiting annular groove 123 can be provided at the closed end of the housing 12 (e.g., Figure 14 The upper end of the housing 12 shown is located at the outer casing 12; however, it is not limited to this, and the limiting annular groove 123 can be provided at other positions of the housing 12.

[0285] To reduce the space occupied by the axial limiting arm 114 on the inner and outer sides of the inner shell 11, in some embodiments, such as Figure 12 and Figure 13 As shown, a limiting arm receiving groove 115 is provided on the side wall of the inner shell 11. The limiting arm receiving groove 115 extends along the first direction Z and penetrates the inner end 11b of the inner shell 11. An axial limiting arm 114 is disposed in the limiting arm receiving groove 115, and the engaging end of the axial limiting arm 114 is located at the inner end 11b. This arrangement can reduce the space occupied by the axial limiting arm 114 on the inner and outer sides of the inner shell 11. The space saved on the inner and outer sides of the inner shell 11 can be used to arrange other structures, which is beneficial to the optimized layout of the inner and outer structures of the inner shell 11.

[0286] In some embodiments, such as Figure 12 and Figure 13 As shown, the axial limiting arm 114 and the side wall of the inner shell 11 are an integral structure, but it is not limited to this. The axial limiting arm 114 and the side wall of the inner shell 11 can also be set separately.

[0287] Figure 15a for Figure 9a The image shows a CC cross-sectional view of the implantation device 400 (with the sensor support 2 in the first initial position). Figure 15b for Figure 15a The diagram shows the state of the sensor holder 2 of the implantation device 400 when it moves to the implantation position (the needle holder 6 is in the second initial position). Figure 15c for Figure 15b The diagram shows the state of the implantation device 400 when the needle extraction seat 6 is moved to the needle extraction position. Figure 16 for Figure 9a An exploded view of the sensor support assembly in the implantable device 400 shown. Figure 17 for Figure 15a The exploded view of the sensor bracket 2 and inner shell 11 shown.

[0288] In some embodiments, such as Figure 15a and Figure 16 As shown, the sensor bracket 2 also has a second cavity 23, which is connected to the receiving cavity 22 and is separated from the first cavity 21.

[0289] The needle extraction seat 6 is at least partially disposed in the second cavity 23 and is used for connection with the puncture needle 320. The needle extraction seat 6 can be in a second initial position along the first direction Z (e.g., Figure 15a and Figure 15b (as shown in the image) and needle withdrawal position (e.g.) Figure 15c The position shown can be moved relative to sensor bracket 2, such as... Figure 15b and Figure 15c As shown, when the needle-pulling seat 6 is in the needle-pulling position, it is farther away from the outer end 2a of the support than when it is in the second initial position.

[0290] like Figure 15a and Figure 16 As shown, the second elastic element 32 is used to apply a second elastic force to the needle holder 6.

[0291] like Figure 15a As shown, the second latching structure 45 includes a needle holder latching part 46 disposed on the needle holder 6 and a bracket latching part 47 disposed on the sensor bracket 2. The second latching structure 45 has a second latching state and a second unlocking state.

[0292] like Figure 15a As shown, when the second locking structure 45 is in the second locking state, the needle seat locking part 46 engages with the bracket locking part 47, and the needle drawer 6 is locked in the second initial position; as Figure 15b and Figure 15c As shown, when the second locking structure 45 is in the second unlocked state, the needle seat locking part 46 separates from the bracket locking part 47, and the needle drawer 6 moves to the needle drawer position under the action of the second elastic force.

[0293] In some embodiments, the pin seat latching portion 46 and the bracket latching portion 47 can have the following structures, specifically as follows: Figure 15a and Figure 16 As shown, the needle holder locking portion 46 includes an elastic arm 461 connected to the needle drawer 6, and a locking protrusion 462 disposed on the elastic arm 461. The bracket locking portion 47 is provided with a locking through hole 471, which is opposite to the side wall of the inner shell 11. When the second locking structure 45 is in the second locking state, the locking protrusion 462 extends into the locking through hole 471, so that the needle holder locking portion 46 and the bracket locking portion 47 are locked together.

[0294] In some embodiments, the second latching structure 45 can automatically unlock when the sensor holder 2 moves to the implantation position, as described below: Figure 16 and Figure 17 As shown, the second snap-fit ​​structure 45 includes a pin seat unlocking part 48, which is disposed on the side wall of the inner shell 11. The bracket snap-fit ​​part 47 is provided with a sliding groove 472, which extends along the first direction Z and communicates with the snap-fit ​​through hole 471. The pin seat unlocking part 48 and the sliding groove 472 are slidably engaged.

[0295] like Figure 15b As shown, when the sensor bracket 2 moves to the implantation position, the needle seat unlocking part 48 can slide relative to the slide groove 472 to the position of the snap-fit ​​hole 471 and squeeze the snap-fit ​​protrusion 462, so that the snap-fit ​​protrusion 462 disengages from the snap-fit ​​hole 471, thereby putting the second snap-fit ​​structure 45 into the second unlocked state.

[0296] In some embodiments, such as Figure 17 , Figure 18 and Figure 19 As shown, Figure 18 for Figure 15a The diagram shows the structure of the sensor support assembly in the implantable device 400 from one viewpoint. Figure 19 for Figure 18 The sensor support assembly shown is a structural schematic diagram from another perspective.

[0297] The slide 472 includes a first slide section 4721 and a second slide section 4722. The first slide section 4721 is located on the side of the snap-fit ​​hole 471 near the outer end 2a of the bracket and is connected to the snap-fit ​​hole 471. The second slide section 4722 is located on the side of the snap-fit ​​hole 471 away from the outer end 2a of the bracket and is connected to the snap-fit ​​hole 471.

[0298] With this setting, such as Figure 15a and Figure 15b As shown, when the sensor bracket 2 moves to the implantation position, the needle seat unlocking part 48 can slide from the first sliding section 4721 into the snap-fit ​​through hole 471 and the second sliding section 4722. In this way, the needle seat unlocking part 48 can fully compress the snap-fit ​​protrusion 462 of the needle seat snap-fit ​​part 46, so that the snap-fit ​​protrusion 462 can be more easily disengaged from the snap-fit ​​through hole 471, thereby making the unlocking of the second snap-fit ​​structure 45 smoother.

[0299] To make unlocking of the second card holder structure 45 smoother, in some embodiments, such as Figure 17 , Figure 18 and Figure 20 As shown, Figure 20 for Figure 15a The sensor support 2 in the implantable device 400 shown is a schematic diagram of its structure from one viewpoint.

[0300] The bracket snap-fit ​​part 47 is a sheet-like structure and includes a first section 47a and a second section 47b arranged along the first direction Z. The inner surface of the first section 47a protrudes from the inner surface of the second section 47b, so that the thickness of the first section 47a is greater than the thickness of the second section 47b. The first sliding groove 4721 is disposed on the first section 47a and penetrates the inner surface of the first section 47a. The snap-fit ​​through holes 471 are all disposed on the second section 47b and penetrate the inner surface of the second section 47b.

[0301] Because the card contact hole 471 is located on the thinner second segment 47b, the depth of the card contact hole 471 is relatively small. Figure 15a and Figure 15b As shown, when the sensor bracket 2 moves to the implantation position, the locking protrusion 462 of the needle seat locking part 46 is more easily disengaged from the inside of the locking through hole 471 under the pressure of the needle seat unlocking part 48, so that the unlocking of the second locking structure 45 can be smoother.

[0302] Among them, such as Figure 17As shown, the inner surfaces of the first segment 47a and the second segment 47b are the surfaces of the first segment 47a and the second segment 47b on the side closest to the central axis of the sensor bracket 2.

[0303] To make unlocking of the second card-connecting structure 45 smoother, in some embodiments, such as Figure 15a and Figure 17 As shown, the maximum depth to which the pin seat unlocking part 48 extends into the first groove 4721 is greater than the thickness of the second section 47b. This configuration, as... Figure 15a and Figure 15b As shown, when the sensor bracket 2 moves to the implantation position, the locking protrusion 462 of the needle seat locking part 46 can be easily squeezed out of the locking through hole 471 by the needle seat unlocking part 48, so that the unlocking of the second locking structure 45 can be smoother.

[0304] In some embodiments, such as Figure 17 As shown, the needle seat unlocking part 48 is a raised rib provided on the inner surface of the side wall of the inner shell 11, and the needle seat unlocking part 48 extends along the first direction Z. Of course, the needle seat unlocking part 48 is not limited to a raised rib; the needle seat unlocking part 48 can also be a protrusion or other structure, depending on the actual situation.

[0305] In some embodiments, such as Figure 15a and Figure 17 As shown, the end of the pin seat unlocking part 48 that is away from the abutment end 11a (e.g.) Figure 15a A first guide slope 481 is provided at the upper end (as shown). The first guide slope 481 is inclined relative to the first direction Z and is used to contact the snap-fit ​​protrusion 462. With this configuration, the first guide slope 481 can guide the snap-fit ​​protrusion 462, so that the snap-fit ​​protrusion 462 gradually disengages from the snap-fit ​​through hole 471 under the guidance of the first guide slope 481. This makes it easier for the snap-fit ​​protrusion 462 to disengage from the snap-fit ​​through hole 471 under the pressure of the pin seat unlocking part 48, thereby making the unlocking of the second snap-fit ​​structure 45 more stable and smooth.

[0306] In some embodiments, such as Figure 17 As shown, the pin seat unlocking part 48 is an integral structure with the side wall of the inner shell 11. However, it is not limited to this; the pin seat unlocking part 48 can also be separately disposed from the side wall of the inner shell 11.

[0307] In some embodiments, such as Figure 15a and Figure 16As shown, the snap-fit ​​protrusion 462 is provided with a second guide slope 4621. The second guide slope 4621 is inclined relative to the first direction Z and is used to contact the pin seat unlocking part 48. With this configuration, the second guide slope 4621 can guide the snap-fit ​​protrusion 462, so that the snap-fit ​​protrusion 462 gradually disengages from the snap-fit ​​through hole 471 under the guidance of the second guide slope 4621. This makes it easier for the snap-fit ​​protrusion 462 to disengage from the snap-fit ​​through hole 471 under the pressure of the pin seat unlocking part 48, thereby making the unlocking of the second snap-fit ​​structure 45 more stable and smooth.

[0308] In some embodiments, such as Figure 19 and Figure 20 As shown, the sensor bracket 2 has a first receiving groove 24 on its side wall and a limiting arm 25 on its side wall, which is located in the first receiving groove 24.

[0309] like Figure 10b and Figure 13 As shown, the inner shell 11 has a rib 111 on its side wall, which extends along the first direction Z. When the sensor bracket 2 is in the implantation position, the limiting arm 25 engages with one end of the rib 111 to prevent the sensor bracket 2 from extending out of the inner shell 11.

[0310] By setting the limiting arm 25 and the rib 111, the two form an axial limiting structure for the sensor bracket 2. This axial limiting structure can restrict the movement range of the sensor bracket 2 along the first direction Z, thereby allowing the sensor bracket 2 to move to a preset position when it is in the implantation position. At the same time, the limiting arm 25 is set in the first receiving groove 24, which can reduce the space occupied by the limiting arm 25 on the inner and outer sides of the sensor bracket 2, thus facilitating the optimized layout of the structure on the sensor bracket 2.

[0311] In some embodiments, such as Figure 20 As shown, the end of the limiting arm 25 near the outer end 2a of the bracket is connected to the cavity sidewall 213 of the first cavity 21, while the end of the limiting arm 25 away from the outer end 2a of the bracket is freely disposed.

[0312] In some embodiments, such as Figure 13 As shown, one end of the rib 111 extends to the abutting end 11a of the inner shell 11, and the other end of the rib 111 extends to the position of the retaining arm receiving groove 112.

[0313] In some embodiments, such as Figure 13 and Figure 17 As shown, the rib 111 and the pin seat unlocking part 48 are offset from each other along the circumference of the inner shell 11. For example, the position of the rib 111 and the position of the pin seat unlocking part 48 are 90 degrees apart along the circumference of the inner shell 11.

[0314] In some embodiments, such as Figure 13 and Figure 17 As shown, the rib 111 and the side wall of the inner shell 11 are an integral structure; however, it is not limited to this, the rib 111 and the side wall of the inner shell 11 can also be set separately.

[0315] In some embodiments, such as Figure 13 and Figure 17 As shown, there are multiple ribs 111 (e.g., two), and the multiple ribs 111 are arranged circumferentially along the inner shell 11. There are multiple limiting arms 25 (e.g., two), and the multiple limiting arms 25 are arranged circumferentially along the sensor bracket 2. Each limiting arm 25 is used to engage with the corresponding rib 111.

[0316] Of course, in other embodiments, the number of protruding ribs 111 and limiting arm 25 may also be one.

[0317] To reduce the space occupied by the bracket latch 47 on the inner and outer sides of the sensor bracket 2, in some embodiments, such as Figure 16 and Figure 17 As shown, a second receiving groove 26 is provided on the side wall of the sensor bracket 2, and the bracket snap-fit ​​part 47 is disposed in the second receiving groove 26.

[0318] In some embodiments, such as Figure 17 and Figure 18 As shown, the bracket snap-fit ​​portion 47 is located near the outer end 2a of the bracket (e.g., Figure 18 The lower end of the bracket locking part 47 shown is connected to the cavity sidewall 213 of the first cavity 21, and the end of the bracket locking part 47 away from the outer end 2a of the bracket (e.g. Figure 18 The upper end of the bracket snap-fit ​​part 47 shown is freely set.

[0319] In some embodiments, such as Figure 15a and Figure 16 As shown, the second snap-fit ​​structure 45 is provided in multiple sets (e.g., two sets); that is; the number of bracket snap-fit ​​parts 47 is multiple (e.g., two), and the multiple bracket snap-fit ​​parts 47 are arranged along the circumference of the inner shell 11; the number of needle seat snap-fit ​​parts 46 is multiple (e.g., two), and the multiple needle seat snap-fit ​​parts 46 are arranged along the circumference of the inner shell 11, and each needle seat snap-fit ​​part 46 is used to snap-fit ​​with the snap-fit ​​through hole 471 on the corresponding bracket snap-fit ​​part 47; the number of needle seat unlocking parts 48 is multiple (e.g., two), and the multiple needle seat unlocking parts 48 are arranged along the circumference of the inner shell 11, and each needle seat unlocking part 48 is slidably engaged with the sliding groove 472 on the corresponding bracket snap-fit ​​part 47.

[0320] Of course, in other embodiments, a set of second snap-fit ​​structures 45 may also be provided.

[0321] In some embodiments, such as Figure 19 , Figure 20 and Figure 21 As shown, Figure 21 for Figure 20 The diagram shows a structural schematic of the sensor support 2 in the implantable device 400 from another perspective. The receiving cavity 22 includes a first receiving cavity 221 and a second receiving cavity 222 that are connected. The first receiving cavity 221 is located at the outer end 2a of the support and is used to house the sensor 310. The second receiving cavity 222 is located on the side of the first receiving cavity 221 away from the abutment end 11a and is used to accommodate the end of the puncture needle 320 away from the puncture end 321 (e.g., ...). Figure 15a The upper end of the puncture needle 320 shown extends into the cavity; the first cavity 21 is an annular cavity and is arranged around the second receiving cavity 222. The first cavity 21 is spaced apart from the first receiving cavity 221 and the second receiving cavity 222.

[0322] Among them, such as Figure 15a and Figure 20 As shown, the first cavity 21 is surrounded by a first cavity wall 211, a second cavity wall 212 and a cavity side wall 213. The cavity side wall 213 includes an outer cavity side wall 2131 and an inner cavity side wall 2132. The inner cavity side wall 2132 surrounds the second receiving cavity 222.

[0323] To facilitate the installation of the filling material 5 within the first cavity 21, in some embodiments, such as Figure 15a and Figure 20 As shown, the second cavity wall 212 is detachably connected to the outer cavity side wall 2131 and the inner cavity side wall 2132.

[0324] The second cavity wall 212 can be detachably connected to the outer cavity sidewall 2131 and the inner cavity sidewall 2132 through snap-fit, adhesive, or other connection methods. For details regarding the structure and arrangement of the filler 5, please refer to [reference needed]. Figures 7a to 7f The settings shown are not repeated here.

[0325] In some embodiments, such as Figure 20 and Figure 21 As shown, the receiving cavity 22 also includes a connecting hole 223, which is disposed between the first receiving cavity 221 and the second receiving cavity 222 and connects the first receiving cavity 221 and the second receiving cavity 222.

[0326] In some embodiments, the pin drawer 6 can have the following structure, such as Figure 22 and Figure 23 As shown, Figure 22 for Figure 15a The diagram shown is a structural schematic of the needle drawer 6 from one perspective. Figure 23 for Figure 22 The diagram shows the structure of the needle extraction seat 6 from another perspective. The needle extraction seat 6 includes a connected seat body 61 and a puncture needle connecting part 62, as shown... Figure 15a As shown, the seat 61 is disposed in the second cavity 23, the needle seat locking part 46 is disposed on the seat 61, and the puncture needle connecting part 62 extends into the second receiving cavity 222 and is detachably connected to the puncture needle 320.

[0327] The puncture needle connection part 62 can be detachably connected to the puncture needle 320 through connection methods such as snap-fit, screw-fit, plug-in, and adhesive.

[0328] In some embodiments, such as Figure 23 As shown, the base 61, the puncture needle connecting part 62, and the needle seat locking part 46 are an integral structure; however, it is not limited to this, the base 61, the puncture needle connecting part 62, and the needle seat locking part 46 can also be set separately.

[0329] In some embodiments, such as Figure 24 and Figure 25 As shown, Figure 24 for Figure 15a The schematic diagram of the sensor assembly 300 shown is as follows. Figure 25 for Figure 24 The exploded view of the sensor assembly 300 is shown. The sensor 310 includes a sensor housing 311 and a sensor implantation part 313. The sensor housing 311 is an annular housing with a central through hole 314, through which a puncture needle 320 passes. A portion of the sensor implantation part 313 extends into the sensor housing 311, and another portion of the sensor implantation part 313 passes through the puncture needle 320, and can be inserted into the implantation site 600 by the action of the puncture needle 320.

[0330] In some embodiments, such as Figure 24 and Figure 25 As shown, the puncture needle 320 includes a needle body 322 and a puncture needle seat 323. One end of the needle body 322 is the puncture end 321, and the other end of the needle body 322 is provided with the puncture needle seat 323, which is disposed in the central through hole 314.

[0331] In some embodiments, such as Figure 24 and Figure 25 As shown, the puncture needle hub 323 is provided with an annular groove 3231; as Figure 23 As shown, the puncture needle connection part 62 includes multiple connecting claws 621 (e.g., three connecting claws 621). The connecting claws 621 are elastic claws. The multiple connecting claws 621 are engaged with the annular groove 3231 to realize the detachable connection between the puncture needle connection part 62 and the puncture needle 320.

[0332] In some embodiments, such as Figure 24 and Figure 25As shown, an adhesive sheet 330 is covered on the bonding surface of the sensor 310, and the adhesive sheet 330 is used to bond the sensor 310 to the implantation site 600. Of course, in some other embodiments, the adhesive sheet 330 may not be provided, and the bonding surface of the sensor 310 may be coated with an adhesive layer.

[0333] The type of the second elastic element 32 is not unique; in some embodiments, such as... Figure 15a and Figure 16 As shown, the second elastic element 32 is at least partially disposed in the second receiving cavity 222. The second elastic element 32 can be a spring. One end of the second elastic element 32 abuts against the needle-drawing seat 6, and the other end of the second elastic element 32 abuts against the cavity wall of the second receiving cavity 222.

[0334] Among them, such as Figure 15a As shown, the second elastic element 32 can be sleeved on the outside of the puncture needle connection part 62.

[0335] The second elastic element 32 is not limited to a spring. In other embodiments, the second elastic element 32 can also be a sheet, which can be V-shaped, W-shaped, wavy, etc. One end of the sheet is connected to the needle-drawing seat 6, and the other end of the sheet is connected to the cavity wall of the second receiving cavity 222.

[0336] In some embodiments, the first elastic member 31 can be indirectly connected to the sensor bracket 2, specifically as follows: Figure 15a and Figure 16 As shown, the implanter 100 also includes a connector 7, which includes a connector body 71 and a second elastic locking arm 72 disposed at the edge of the connector body 71. The connector body 71 is disposed at the inner end 2b of the bracket, which is the end of the sensor bracket 2 away from the abutment end 11a.

[0337] The sensor bracket 2 has a snap-fit ​​hole 27 on its side wall; the second elastic snap-fit ​​arm 72 snaps into the snap-fit ​​hole 27, and the edge of the connecting seat 71 abuts against the inner end 2b of the bracket, so that the connecting seat 7 is fixed relative to the sensor bracket 2 along the first direction Z. One end of the first elastic member 31 is connected to the outer shell 12, and the other end of the first elastic member 31 extends from the inner end 11b of the shell into the inner shell 11 and is connected to the connecting seat 71.

[0338] The second elastic locking arm 72 engages with the locking hole 27, thus preventing the connecting seat 7 from moving away from the outer end 2a of the bracket (e.g., Figure 15a (In the upward direction); by abutting the edge of the connecting seat 71 against the inner end 2b of the bracket, the connecting seat 7 can be prevented from moving towards the outer end 2a of the bracket (e.g., in the upward direction); Figure 15a The connecting seat 7 can be moved in the downward direction. This allows the connecting seat 7 to be fixed relative to the sensor bracket 2 in the first direction Z.

[0339] Compared to the scheme where the connector 7 is connected to the sensor bracket 2 via fasteners (such as screws), the connector 7 is connected to the sensor bracket 2 via the above-mentioned snap-fit ​​structure, which facilitates the installation of the connector 7 and the sensor bracket 2, eliminates the need to tighten the fasteners, and thus helps to shorten the installation time of the connector 7.

[0340] To facilitate the removal of the connector 7 from the sensor bracket 2, in some embodiments, such as Figure 15a and Figure 16 As shown, the second elastic locking arm 72 extends into the inner side wall of the sensor bracket 2 and engages with the locking hole 27. This arrangement facilitates the unlocking of the locking structure between the connecting seat 7 and the sensor bracket 2, thereby making it easier to detach the connecting seat 7 from the sensor bracket 2. Specifically, when it is necessary to remove the connecting seat 7, simply press the locking end of the second elastic locking arm 72 on the outer side wall of the sensor bracket 2 to cause the second elastic locking arm 72 to elastically deform and disengage from the locking hole 27, thus unlocking the connection between the connecting seat 7 and the sensor bracket 2.

[0341] In some embodiments, such as Figure 16 As shown, the second elastic locking arm 72 extends along the first direction Z.

[0342] In some embodiments, such as Figure 16 As shown, there are multiple snap-fit ​​holes 27 (e.g., four), and the multiple snap-fit ​​holes 27 are arranged around the sensor bracket 2; there are multiple second elastic snap-fit ​​arms 72 (e.g., four), and the multiple second elastic snap-fit ​​arms 72 are arranged around the connecting base 71, and each second elastic snap-fit ​​arm 72 is snapped into the corresponding snap-fit ​​hole 27.

[0343] The type of the first elastic element 31 is not unique; in some embodiments, such as... Figure 15a and Figure 16 As shown, the first elastic element 31 can be a spring. One end of the first elastic element 31 abuts against the inner wall of the outer shell 12, and the other end of the first elastic element 31 abuts against the connecting seat 71.

[0344] To reduce vibration of the first elastic element 31 during compression or stretching, in some embodiments, such as Figure 15a and Figure 16 As shown, a positioning sleeve 124 is provided on the inner wall of the outer shell 12, and the connecting seat 7 also includes a positioning post 73. The positioning post 73 is located on the side of the connecting seat body 71 away from the outer end 2a of the bracket. One end of the first elastic member 31 extends into the positioning sleeve 124 and abuts against the inner wall of the outer shell 12. The other end of the first elastic member 31 is sleeved on the positioning post 73 and abuts against the connecting seat body 71.

[0345] Among them, such as Figure 15aAs shown, the positioning sleeve 124 is disposed on the shell wall of the closed end of the outer shell 12.

[0346] In some embodiments, such as Figure 15a and Figure 16 As shown, positioning post 73 is a hollow post.

[0347] In some embodiments, such as Figure 15a and Figure 16 As shown, the connecting base 71, the second elastic locking arm 72, and the positioning post 73 are an integral structure; however, it is not limited to this, the connecting base 71, the second elastic locking arm 72, and the positioning post 73 can also be set separately.

[0348] The first elastic element 31 is not limited to a spring. In other embodiments, the first elastic element 31 can also be a spring sheet, which can be V-shaped, W-shaped, wavy, etc. One end of the spring sheet is connected to the inner wall of the outer shell 12, and the other end of the spring sheet is connected to the connecting seat 71.

[0349] The first elastic element 31 is not limited to being connected to the sensor bracket 2 via the connecting seat 7. In other embodiments, the first elastic element 31 can also be directly connected to the sensor bracket 2.
