Description

Technical Field

[0001] This disclosure generally relates to the field of medical device technology. More specifically, this disclosure relates to a detection device applicator and a detection system. Background Technology

[0002] In the current field of medical testing devices, it is common to use transmitters that are applied to the human body. These transmitters obtain physiological indicators such as blood sugar levels through probes inserted into the body, process the information using internal control circuitry, and then transmit it to an external receiving device. Such devices typically require an applicator to be applied to the body, but most applicators on the market are complex to operate and difficult for users to use.

[0003] In view of this, there is an urgent need to provide a detection device applicator and detection system so that the detection device can be applied efficiently and quickly with simple operation, reducing the risk of medical accidents caused by improper use by patients. Summary of the Invention

[0004] In order to at least address one or more of the technical problems mentioned above, this disclosure provides a detection device applicator and detection system in several aspects.

[0005] In a first aspect, this disclosure provides a detection device applicator, comprising: an abutment member for abutting a human body, the abutment member having a first locking portion; a housing including a first trigger portion and a second trigger portion, the housing being movable relative to the abutment member; a first elastic locking mechanism including a delivery mechanism and a first energy storage member abutting thereto, the delivery mechanism including a second locking portion and the delivery mechanism being locked by the first locking portion; and a second elastic locking mechanism including a return mechanism and a second energy storage member abutting thereto, the return mechanism being locked by the second locking portion, wherein the movement of the abutment member relative to the housing enables the first trigger portion to unlock the first locking portion, allowing the first energy storage member to drive the delivery mechanism to move, thereby enabling the second trigger portion to unlock the second locking portion.

[0006] In some embodiments, the first trigger is a housing clearance hole on the housing, and the first locking part includes an elastic arm on the abutment member. The elastic arm is used to abut against the inner wall of the housing and can move radially toward the housing clearance hole when aligned with it, so as to unlock the delivery mechanism.

[0007] In some embodiments, the elastic arm is provided with a locking drive block that protrudes radially inward, the locking drive block being used to abut against the delivery mechanism to limit its movement.

[0008] In some embodiments, the locking drive block is provided with a drive ramp, which is used to cooperate with the push top of the delivery mechanism to drive the elastic arm to move radially to avoid the push top.

[0009] In some embodiments, the housing clearance hole also includes an upward-facing check surface. After the elastic arm moves toward the housing clearance hole to release the delivery mechanism, the radially inner side of the elastic arm is abutted radially outward by the delivery mechanism and extends into the housing clearance hole. The check surface is used to abut against the bottom end of the elastic arm to prevent the housing from moving in the opposite direction.

[0010] In some embodiments, the delivery mechanism includes a delivery sleeve, and the return mechanism includes a return sleeve, the return sleeve being disposed radially inside the delivery sleeve.

[0011] In some embodiments, the delivery sleeve is provided with a check surface, which can reverse and abut against the elastic arm after the delivery mechanism is unlocked and moved.

[0012] In some embodiments, the second triggering part is a triggering cylinder extending from the inner top wall of the housing into the housing, and the second locking part is an elastic locking hook disposed on the delivery sleeve. The triggering cylinder surrounds and radially limits the elastic locking hook. After the triggering cylinder disengages from the elastic locking hook to release the limitation on the elastic locking hook, the second energy storage member drives the return sleeve to push the elastic locking hook upward, causing the elastic locking hook to undergo elastic deformation to release the return sleeve.

[0013] In some embodiments, the first energy storage element is a first spring, and the second elastic locking mechanism is disposed radially inside the first spring.

[0014] In some embodiments, the second energy storage element is a second spring, and both the first spring and the second spring abut against the same side of the delivery mechanism.

[0015] In some embodiments, the housing and / or the delivery mechanism are further provided with a spring support member, which is disposed at the axial end of the first spring and / or the second spring.

[0016] In some embodiments, the housing is provided with at least two first trigger parts, and the abutment is provided with a first locking part corresponding to the number of first trigger parts.

[0017] In some embodiments, the device further includes a cover detachably connected to the abutment member. The cover also includes a lateral hook, which includes a radially inwardly projecting hook portion. The radially inwardly projecting end face of the hook portion is used to abut against the outer surface of the protective shell. The positioning side of the hook portion abuts against at least one positioning plane of the protective shell to limit its rotational movement.

[0018] In some embodiments, the device further includes a cover, which includes an inner cylinder and an outer cylinder disposed circumferentially outside the inner cylinder. The outer circumferential surface of the inner cylinder abuts against the inner side of the abutment, and the end of the outer cylinder abuts against the end of the abutment.

[0019] In a second aspect, this disclosure provides a detection system including a detection device applicator according to the first aspect and several embodiments; and a detection device assembly including a detection device and auxiliary and protective components disposed on both sides of the detection device. The detection device includes a housing and electronic components disposed within the housing. The housing includes a housing channel penetrating the housing. The auxiliary and protective components are capable of engaging in the housing channel and are capable of rotating relative to each other to a locked or unlocked position.

[0020] In some embodiments, the electronic component further includes a detection needle, the auxiliary component includes a needle hub and a puncture needle fixedly connected to the needle hub, and the protective component includes a protective shell. The puncture needle is used to assist the detection needle in being inserted into the human body.

[0021] In some embodiments, in the locked position, the lower end face of the needle hub is flush with or recessed inward relative to the lower end face of the detection device.

[0022] With the detection device applicator provided above, the detection device applicator of this disclosed embodiment can efficiently and quickly complete the application of the detection device with simple operation by means of a first elastic locking mechanism and a second elastic locking mechanism triggered by its action, reducing the risk of medical accidents caused by improper use by patients.

[0040] The technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, not all of them. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0041] It should be understood that the terms “comprising” and “including” used in this disclosure and claims indicate the presence of the described features, integrals, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or collections thereof.

[0042] It should also be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of this disclosure. As used in this disclosure and claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used in this disclosure and claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes such combinations.

[0043] As used in this specification and claims, the term "if" may be interpreted, depending on the context, as "when," "once," "in response to determination," or "in response to detection." Similarly, the phrase "if determined" or "if [described condition or event] is detected" may be interpreted, depending on the context, as "once determined," "in response to determination," "once [described condition or event] is detected," or "in response to detection of [described condition or event]."

[0044] The specific embodiments disclosed herein will now be described in detail with reference to the accompanying drawings.

[0045] In view of this, the present disclosure provides a detection device applicator, which, by providing a first locking mechanism and a second locking mechanism that interlock with each other, can complete the application of the detection device through simple operation.

[0046] For clarity and ease of understanding, in the following description, the side of the detection device that contacts the human body is generally considered the vertically lower side of the device's applicator, the side of the detection device away from the human body is considered the vertically upper side, the direction parallel to the contact surface between the detection device and the human body is considered the horizontal direction, the direction along the horizontal direction towards the detection needle of the detection device is considered radially inward, and the direction along the horizontal direction away from the center of the detection needle is considered radially outward. Unless otherwise specified, the positional descriptions of other related components will also be based on this. The purpose of the above description is merely to provide a reference direction for describing the relative positional relationships of the various structures, and not to limit the actual structural arrangement of the embodiments in this disclosure.

[0047] See Figure 1 and Figure 2 , Figure 1 An exemplary perspective view of a detection apparatus applicator according to some embodiments of this disclosure is shown; Figure 2 An exemplary exploded view of a detection apparatus applicator according to some embodiments of this disclosure is shown.

[0048] In some embodiments, the detection device applicator 100 may include a housing 10, an abutment 20 snapped onto the housing 10, and a cover 80 detachably connected to the abutment 20. The cover 80 is removable relative to the housing 10, which is vertically movable relative to the abutment 20. The detection device applicator can be used to hold and lock the detection device assembly. The abutment 20, for example, can be used to abut against a human body surface to position the detection device of the detection device assembly, and the holding of the detection device can be released by relative movement between the housing 10 and the abutment 20, allowing the detection device to be placed or implanted into the human body. The detection device applicator may also include a first resilient locking mechanism 30 and a second resilient locking mechanism 40 releasably connected to the first resilient locking mechanism 30. The detection device may, for example, be disposed on the first resilient locking mechanism 30, which may, for example, be used to move vertically downward and apply the detection device to the human body. An auxiliary component of the detection device may, for example, be connected to the second locking mechanism, which is used to move vertically upward and remove the auxiliary component.

[0049] Specifically, in some embodiments, the detection device can be used to analyze human analytes to measure human indicators such as blood glucose levels. The detection device may include a detection needle for insertion into the human body to acquire biological information. The detection device assembly may also include auxiliary components connected to the detection device to assist the detection needle in insertion into the human body. The first elastic locking mechanism 30 may include a delivery mechanism and a first energy storage member abutting thereto, while the second elastic locking mechanism 40 may include a return mechanism and a second energy storage member abutting thereto. The delivery mechanism may, for example, be abutted vertically by the first locking portion of the abutment member 20, thereby compressing the first energy storage member vertically and locking it in the delivery holding position. The return mechanism may be abutted vertically by the second locking portion of the delivery mechanism, thereby compressing the second energy storage member vertically and locking it in the return holding position. The housing 10 also includes a first trigger portion for releasing the first locking portion and a second trigger portion for releasing the second locking portion. The first energy storage member can drive the delivery mechanism to move to the installation position and install the detection device, and when the delivery mechanism moves to the detection device installation position, the second trigger portion releases the second locking portion.

[0050] See also Figures 3a to 3c , Figure 3a An exemplary cross-sectional view of a detection apparatus applicator according to some embodiments of this disclosure is shown, wherein a first resilient locking mechanism 30 is in the delivery holding position and a second resilient locking mechanism 40 is in the return holding position; and Figure 3b It shows Figure 3a A magnified view of part A in the middle; Figure 3c It shows Figure 3aA partially enlarged schematic diagram of part B. Specifically, in some embodiments, the housing 10 may be generally hollow and cylindrical, with its vertical lower side open. The abutment member 20 may be generally cylindrical, extending vertically, and may at least partially fit onto the housing 10, and may move relative to the housing 10 in the vertical direction.

[0051] The first elastic locking mechanism 30's delivery mechanism may include a delivery sleeve 31, and the first energy storage element may include a first spring 32 arranged vertically. The upper end of the first spring 32 may abut against the housing spring support portion of the housing 10, while its lower end may abut against the first spring abutment portion of the delivery sleeve 31, thereby providing a spring thrust in the first direction toward the delivery sleeve 31 that is vertically away from the housing 10. The second elastic locking mechanism 40's return mechanism may, for example, include a return sleeve 41, and the second energy storage element may include a second spring 42 arranged vertically. The lower end of the second spring 42 abuts against the second spring abutment portion of the delivery sleeve 31, while its upper end may abut against a return support surface of the return sleeve 41. Thus, the second spring 42 can provide a spring thrust in the return sleeve 41 that is vertically away from the delivery sleeve 31.

[0052] In some embodiments, the abutment member 20 may include an inner abutment sleeve 25 partially nested radially inward of the housing 10, and an outer abutment sleeve 29 partially disposed on the outer side of the housing 10. The delivery sleeve 31 may, for example, be disposed inside the inner abutment sleeve 25, with its outer periphery adjacent to the inner wall of the inner abutment sleeve 25. The delivery sleeve 31 may, for example, include a generally cylindrical delivery sleeve 311 and a delivery platform 313 disposed at the bottom of the delivery sleeve 311. The delivery platform 313 may, for example, be a plate-shaped platform extending radially inward from the bottom of the delivery sleeve 311. Furthermore, a second platform 314 may be fixedly disposed at the lower end of the delivery platform 313 on the bottom side of the delivery sleeve 31. The second platform 314 may also be generally plate-shaped extending horizontally. A detection device may be disposed on the lower surface of the second platform 314.

[0053] The outer sleeve 29 can be generally cylindrical, with its bottom fixedly connected to the inner sleeve 25. Two vertically extending protective side pieces 27 can be provided on its upper side, which can radially cover openings or other structures formed on the side of the housing 10. Additionally, the housing 10 can have vertically extending guide grooves that match the protective side pieces 27, allowing the protective side pieces 27 to circumferentially engage with the guide grooves to prevent relative rotation between the abutment 20 and the housing 10. A vertical and / or radial clearance can be provided between the abutment 20 and the housing 10. For example, by adjusting the dimensions of the vertical and radial connection portions between the abutment 20 and the housing 10, the adjacent portions on the outer sides will not directly contact each other after pressing the housing 10 relative to the abutment 20, but will maintain a certain gap. This prevents the user's hand from being pinched during or after movement.

[0054] Those skilled in the art will understand that although the above description depicts a configuration where a delivery platform 313 of a delivery sleeve 31 is positioned at the bottom of a delivery outer sleeve 311, and a second platform 314 is fixedly connected to the bottom end of the delivery platform 313, this disclosure does not limit the specific composition of the delivery sleeve 31. For example, in some embodiments, the delivery platform 313 and the delivery outer sleeve 311 can be two separate components, which can be fixedly connected to each other by snap-fit ​​or other means, thereby reducing production difficulty. In some other embodiments, the delivery sleeve 31 and the second platform 314 can be integrally formed to obtain higher structural strength. Furthermore, the delivery platform 313 and the second platform 314 can be positioned at the bottom of the delivery outer sleeve 311 by snap-fit ​​or other means, or they can be configured to have the same outer diameter as the delivery outer sleeve 311, and are integrally axially connected to one axial end of the delivery outer sleeve 311 by snap-fit ​​or adhesive. In some other embodiments, the delivery platform 313 may not be plate-shaped; for example, it may be formed with a certain curvature or inclination, or it may be composed of multiple stiffening plate assemblies.

[0055] The delivery platform 313 of the delivery sleeve 31 can be vertically aligned with an inner top wall of the housing 10. Therefore, the first spring abutment portion can be disposed on the upper side of the delivery platform 313, while the housing spring support portion can be disposed on the inner top wall of the housing 10. For example, in some embodiments, one end of the first spring 32 along a first direction can directly abut against the inner top wall, and the other end can directly abut against the upper surface of the delivery platform 313. In other embodiments, the first spring abutment portion can include a plurality of platform support ribs 313a extending vertically upwards on the upper plane of the delivery platform 313, and the upper surfaces of the plurality of platform support ribs 313a can be configured as flush planes for abutting against the end face of the first spring 32. Similarly, the housing spring support portion can also include a plurality of housing support ribs extending vertically downwards, and the lower end faces of the plurality of housing support ribs can also be configured as flush planes for supporting the end face of the first spring 32. By setting the shell support ribs and platform support ribs 313a, the structural strength of the shell 10 and the delivery platform 313 is enhanced with less material, while the actual length required for the spring to provide elastic thrust in the vertical direction is shortened, thereby saving costs and reducing the occurrence of twisting or jamming when the spring is too long.

[0056] Furthermore, in some embodiments, a spring positioning mechanism for positioning the end of the first spring 32 may be provided on the first spring abutment portion and the housing spring support portion. For example, a spring positioning ring or positioning block matching the spring diameter may be provided on the inner or outer side of the spring to prevent the spring from shifting during installation or use.

[0057] In some embodiments, the return sleeve 41 may be generally a hollow cylindrical shape that opens downwards, with a horizontal top plate 411 on its upper side. A through hole may be provided in the central portion of the delivery platform 313, and the middle portion of the second platform 314 may protrude upwards through this through hole. A return support surface may be provided on the lower surface of the top plate 411 of the return sleeve 41, and a second spring abutment portion may be provided on the upper surface of the portion of the second platform 314 protruding from the aforementioned through hole. A second spring limiting mechanism may be provided on both the return support surface and the second spring abutment portion to limit the end of the second spring 42. For example, a spring limiting ring matching the inner diameter of the second spring 42 may be provided on the second spring abutment portion, and the lower end of the second spring 42 may be sleeved on the outside of the spring limiting ring to prevent it from sliding horizontally. A return latch 413 for needle removal may be provided on the lower surface of the top plate 411 of the return sleeve 41, and the return latch 413 may be, for example, a plurality of protrusions extending downwards in a vertical direction. The tip of the extension of the return latch 413 can, for example, protrude laterally inward in a radial direction to be fixedly connected to the auxiliary component of the detection device assembly by means of snap-fit ​​or other means, so that the auxiliary component can be pulled out in a vertical direction when the return sleeve 41 moves vertically relative to the second platform 314. The radially outer side of the return latch 413 can also be used as a spring limiting part to limit the horizontal position of the second spring 42.

[0058] In some embodiments, the first locking part is disposed on the side wall of the abutting inner sleeve 25 of the abutting member 20. The first locking part may be formed as a spring hook that can move elastically in the radial direction, and the first triggering part may be formed as a housing clearance hole 101 disposed on the housing 10 for avoiding the first locking part.

[0059] In some embodiments, the abutment member 20 may be made entirely of a plastic material such as polycarbonate, so that the spring hook structure formed therefrom can have a certain elastic deformation capability. The first locking part may, for example, include an elastic arm 202 that is separated from the side wall portion of the abutment inner sleeve 25 and extends in a vertical direction. The elastic arm 202 includes a radial stop 202a disposed at the end of the extended portion of the elastic arm 202. The elastic arm 202 can be used to provide an elastic deformation amount in the radial direction, so that the radial stop 202a can move in the radial direction under the drive of a radial force. The housing 10 is arranged radially outside the radial stop 202a. The housing 10 may be provided with a housing abutment wall for radially abutting the radial stop 202a, and a housing clearance hole 101 for radially avoiding the radial stop 202a. A push top 31a can be provided at the vertical lower end of the radially outer side of the delivery sleeve 31, while a locking drive block 202b for abutting against the push top 31a can be provided on the radially inner side of the radial stop block 202a. For example, an upward driving slope 202c can be provided on the locking drive block 202b. The driving slope 202c contacts the push top 31a and is used to slide obliquely against it when it is abutted by the push top 31a in the vertical direction, so as to drive the elastic arm 202 to elastically deform, so that the radial stop block 202a abuts radially outward.

[0060] Those skilled in the art will understand that although the above describes a configuration in which the radial stop 202a extends radially outward by means of the spring force of the first spring 32 and the cooperation of the push top 31a with the locking drive block 202b having the drive ramp 202c, this disclosure does not limit the unlocking method of the first locking part.

[0061] See Figure 4 , Figure 4 An exemplary cross-sectional view of a detection device applicator according to some embodiments of this disclosure is shown. In some embodiments, the general structure of the detection device applicator 400 may be similar to that of the detection device applicator 100 in some embodiments of this disclosure. For example, the detection device applicator 400 may include a housing 410, an abutment 420 snapped onto the housing 410, and a cover 480 detachably connected to the abutment 420. The cover 480 may be removed relative to the housing 410, which is movable in a vertical direction relative to the abutment 420. The detection device applicator 400 may be used to hold and lock the detection device assembly, the abutment 420 may be used, for example, to abut against a human body surface to position the application location of the detection device of the detection device assembly, and to release the holding of the detection device by relative movement of the abutment 420 with respect to the housing 410, thereby placing the detection device onto the human body.

[0062] The detection device applicator 400 may include an elastic arm 422 disposed on the side wall of the abutment member 420. When the housing 410 is pressed downward relative to the abutment member 420, a locking drive block 422b protruding radially inward at the end of the elastic arm 422 may be pushed by a pusher 431a at the bottom of the delivery sleeve 431. A drive ramp may be provided on one or both of the locking drive block 422b and the pusher 431a, and the two are in contact with each other by means of the drive ramp. The pusher 431a causes the elastic arm 422 to elastically deform radially outward and extend into the housing clearance hole 401 provided on the side wall of the housing 410. Unlike the detection device applicator of the above embodiment in this disclosure, the elastic arm 422 may not be provided with a radially outward protruding radial stop, but instead directly deforms outward and extends into the housing clearance hole 401 through the cooperation of the locking drive block 422b on its inner side and the pusher 431a. Therefore, the structure of the applicator used for the detection device can be simpler, and the radial layout can be more compact.

[0063] Alternatively, in some embodiments, the radial stop 202a may be made of an elastic material, allowing it to extend into the housing clearance hole 101 through its own elastic deformation, etc. Furthermore, in some embodiments, two symmetrical housing clearance holes 101 may be provided on the housing 10, and two corresponding symmetrical elastic arms 202 may be provided on the lower inner sleeve of the abutment member 20. More housing clearance holes 101 and elastic arms 202 may also be provided to provide a more stable locking force. By providing the housing clearance holes 101 and their corresponding radial stops 202a, the unlocking of the first elastic locking mechanism 30 can be automatically achieved by the spring force of the first spring 32, avoiding unnecessary operational difficulties and discomfort caused by the user applying a large pushing force to the detection device.

[0064] Therefore, when the radial stop 202a abuts against the outer wall of the housing, the delivery sleeve 31 of the first elastic locking mechanism 30 cannot drive the elastic hook to move radially outward. At this time, the locking drive block 202b on the radially inner side of the elastic hook abuts against the delivery sleeve 31 in the vertical direction by means of its driving inclined surface 202c, compressing the first spring 32 and holding it in the delivery holding position. By setting the distance between the delivery holding position and the end face of the abutment member 20 used to abut against the human body, the detection device can be completely housed axially inside the housing 10 and the abutment member 20, thereby preventing the user from accidentally touching the detection device or the detection device from being contaminated by the external environment.

[0065] In some embodiments, a check groove 31b may be provided on the circumferential outer side of the delivery sleeve 31. The check groove 31b may be, for example, a groove that is radially recessed into the outer wall of the delivery sleeve 31 and extends vertically for a certain distance. An upward-facing check surface 31c is provided at the lower end of the groove. The check groove 31b is used to at least partially accommodate the radially rebounding locking drive block 202b after the delivery sleeve 31 has fully ejected. When the delivery sleeve 31 is pushed upwards vertically, the check surface 31c abuts against the lower end face of the locking drive block 202b, thereby preventing the delivery sleeve 31 from moving in the opposite direction. Furthermore, the abutment between the bottom end of the elastic arm 202 and the bottom surface of the housing clearance hole 101 prevents the housing 10 from rebounding. This prevents the user from accidentally pressing the delivery mechanism after use, causing the puncture needle to protrude and resulting in a hazard due to user contact with the puncture needle. In some embodiments, the check surface 31c can also be provided on the upper end surface of the delivery sleeve 31 in the vertical direction, in which case there is no need to provide the check groove 31b.

[0066] In addition, in some embodiments, a radially inwardly protruding limiting block can be provided on the inner sidewall of the abutting inner sleeve 25, and a limiting groove corresponding to the limiting block can be provided on the delivery sleeve 31. The limiting block includes an upward limiting surface, which is used to abut against a downward end face of the limiting groove in the vertical direction when the delivery sleeve 31 extends, thereby limiting the extension distance of the delivery sleeve 31. In some embodiments, the limiting block can also play a circumferential limiting role, that is, the cooperation between the limiting block and the limiting groove prevents relative rotation between the abutting member 20 and the delivery sleeve 31. In some embodiments, a limiting guide groove is provided on the inner wall of the abutting inner sleeve 25, and a limiting guide block corresponding to the limiting guide groove is provided on the outer sidewall of the delivery sleeve 31. The limiting guide groove can cooperate with the limiting guide block to limit and guide the vertical direction of the delivery sleeve 31.

[0067] In some embodiments, the second triggering part may be formed as a trigger cylinder 107 extending downward in a vertical direction from the inner top wall of the housing 10, while the second locking part may be one or more elastic locking hooks 313b extending upward from the upper surface of the delivery platform 313. The one or more elastic locking hooks 313b may be arranged at an angle to each other, for example, each elastic locking hook 313b including an elastic hook body 313c extending upward in a vertical direction and a hook head 313d protruding radially inward from the elastic hook body 313c. The elastic hook body 313c may, for example, be elastically movable in a radial direction under the action of a radial force. The one or more elastic locking hooks 313b may surround the outer periphery of the return sleeve 41 of the return mechanism, and the multiple elastic locking hooks 313b together abut against the upper end of the return sleeve 41 in a vertical direction. In some embodiments, the hook head 313d of the elastic locking hook 313b includes a downward hook head slope 313e, while the upper outer periphery of the return sleeve 41 may be provided with an unlocking slope 414 corresponding to the hook head slope 313e. The unlocking slope 414 may be, for example, a chamfer formed on the upper outer periphery of the return sleeve 41. The unlocking slope 414 can be used to abut against the hook head slope 313e, so that the upward thrust of the second spring 42 is converted into an outward force in the radial direction through the action between the slopes.

[0068] The trigger cylinder 107 can be sleeved on the radially outer side of one or more elastic locking hooks 313b, and its radially inner wall is used to abut against the elastic hook body 313c radially inward, preventing it from undergoing elastic deformation under the spring force of the second spring 42 and driving the hook head 313d to move radially outward elastically. Thus, the return mechanism can be locked vertically by means of one or more elastic locking hooks 313b, thereby keeping the second spring 42 in a compressed state to lock the return mechanism in the return holding position.

[0069] In some embodiments, by setting the positions of the first trigger portion and the second trigger portion on the housing 10 along the axial direction, a single movement of the housing 10 can trigger the unlocking of the first elastic locking mechanism 30, and after the second elastic locking mechanism 40 moves to the installation position of the detection device, the unlocking of the second elastic locking mechanism 40 can be automatically triggered.

[0070] See Figure 5 , Figure 5An exemplary cross-sectional view of the application device of some embodiments of this disclosure is shown. Specifically, in some embodiments, the first trigger portion is formed as a housing clearance hole 101 for avoiding the radial stop 202a, and the second trigger portion is a trigger cylinder 107 for restricting the elastic locking hook 313b. When the first elastic locking mechanism 30 and the second elastic locking mechanism 40 are in the delivery holding position and the return holding position, the first distance between the lower end face of the housing clearance hole 101 in the vertical direction and the lower end face of the radial stop 202a is D1, the second distance between the lower edge of the inner wall of the trigger cylinder 107 and the top end of the radial outer wall of the elastic locking hook 313b is D2, and the third distance between the detection device from the initial position to the detection device installation position is D3. In actual use, when the abutment 20 is pressed against the human skin 300 and the detection device is installed, the pressed part of the human skin 300 will bulge into the abutment due to the elasticity of the skin. Therefore, the value of the third distance D3 can be less than the distance from the bottom surface of the detection device to the bottom surface of the abutment 20 in the initial position.

[0071] If the sum of the first distance D1 and the second distance D2 is set to be equal to or less than the third distance D3, then after the first elastic locking mechanism 30 is released by moving the housing 10 relative to the abutment 20 by the first distance D1, the delivery mechanism, under the spring force of the first spring 32, will drive the detection device to continue moving, so that the device moves from its initial position by the third distance D3 and is installed on the human body. At this time, the third distance D3 makes the relative movement distance between the delivery mechanism and the housing 10 equal to the third distance D3 minus the first distance D1. If the relative movement distance is greater than or equal to the second distance D2, then the second elastic locking mechanism 40 can be automatically released.

[0072] In some embodiments, the first distance D1 described above can be set to, for example, 4±1mm, so that the pressing action when installing the detection device can be triggered more easily, but will not be accidentally released due to disturbance.

[0073] In some embodiments, the first spring 32 can be disposed circumferentially outside the second spring 42. Specifically, the inner diameter of the first spring 32 can be larger than the outer diameter of the return sleeve 41, so that the second elastic locking mechanism 40 can be integrally disposed radially inside the first spring 32. Furthermore, the axial positions of the first spring 32 and the second spring 42 can be aligned with the center of the auxiliary component. Thus, not only can the spring force application positions of the first spring 32 and the second spring 42 be concentrically arranged, but the pushing pressure of the first spring 32 on the detection device and the return pulling force of the second spring 42 can also be aligned with the center of the auxiliary component. This ensures that the force direction of the auxiliary component is consistent with the applied force direction, whether the detection device is applied or the auxiliary component is withdrawn, reducing the occurrence of skewed insertion or withdrawal directions of the detection needle due to force offset. Furthermore, the lower end of the first spring 32 can be disposed on the upper surface of the delivery platform 313, and the lower end of the second spring 42 can be disposed on the upper surface of the second platform 314 fixedly connected to the delivery platform 313, resulting in a simpler overall structure and a more compact layout. In some embodiments, the delivery platform 313 and the second platform 314 can be integrally formed, thereby further simplifying the structure of the device and improving the structural strength at the same time.

[0074] Those skilled in the art will understand that although the above description presents a structure in which a first spring 32 is sleeved on the outside of a trigger cylinder 107 and a second elastic locking mechanism 40 is disposed inside the first spring 32, the present disclosure does not limit the specific arrangement of the first elastic locking mechanism 30 and the second elastic locking mechanism 40. For example, the first spring 32 and the second spring 42 can be arranged at intervals in the horizontal direction, or multiple first springs 32 can be arranged at intervals at a certain angle, and multiple first springs 32 can be arranged around the outer periphery of the second spring 42, etc. The goal is to ensure that the first elastic locking mechanism 30 and the second elastic locking mechanism 40 can operate independently without interfering with each other. Furthermore, in some embodiments, the elastic force of the first spring 32 and the second spring 42 is determined by their ability to overcome the locking resistance of the corresponding first elastic locking mechanism 30 or second elastic locking mechanism 40. In some embodiments, spring support portions can be provided to reduce the total length required for the first spring 32 and / or the second spring 42; for example, support ribs can be provided on the top and / or bottom sides of the first spring 32 and / or the second spring 42. This allows for a reduction in spring length, which helps eliminate unwanted radial forces caused by torsional skewing due to excessive spring length during use. Furthermore, a first spring 32 or a second spring 42 with a smaller wire diameter and lower pressure can be used. This makes axial deformation of the first spring 32 or the second spring 42 easier and facilitates operation.

[0075] See Figure 6 and Figure 7 , Figure 6An exemplary perspective view of the housing cover of the detection apparatus applicator according to some embodiments of this disclosure is shown; Figure 7 An exemplary perspective view of the abutment of an applicator of a detection device according to some embodiments of this disclosure is shown. In some embodiments, the cover 80 may include a horizontal bottom wall and concentrically arranged inner cylinder 82 and outer cylinder 81 extending upward from the bottom wall. The inner cylinder 82 may extend vertically higher than the outer cylinder 81, and a locking block 83 extending radially outward from the sidewall of the inner cylinder 82 may be provided between the inner cylinder 82 and the outer cylinder 81. The cover 80 may be engaged with the bottom surface of the abutment 20 from bottom to top, wherein the inner cylinder 82 is used to radially abut the inner side surface of the abutment 20, and the upper end surface of the outer cylinder 81 is used to abut the bottom end surface of the abutment surface. The sealing performance of the cover 80 to the interior of the detection device applicator is improved by using the inner cylinder 82 and outer cylinder 81, which are individually connected to the abutment 20. Furthermore, by setting the inner cylinder 82 higher than the outer cylinder 81, it is possible to provide a guide for the direction of rotation when the cover 80 and the abutment 20 rotate relative to each other, while ensuring convenient installation and disassembly, thus preventing tilting during rotation.

[0076] The locking block 83 can be inserted into the locking groove 261 provided on the bottom surface of the abutment 20, and screwed into the locking positioning groove 262 at the bottom of the abutment 20 by the mutual rotation between the cover 80 and the abutment 20, thereby locking relative to the abutment 20 in the vertical direction. In some embodiments, the upper end surface of the locking block 83 can also be used to abut against the lower end surface of the housing 10 in the vertical direction after being screwed into the locking positioning groove 262, so as to prevent relative movement between the housing 10 and the abutment 20 in the vertical direction when the cover is on.

[0077] In some embodiments, a protective component is further provided on the lower side of the detection device. This protective component may be located, for example, on the vertically lower side of the detection device, and may be rotatably engaged with an auxiliary component. The protective component may include a generally cylindrical hollow protective shell that opens upwards, with a connector at its open end face for rotatable engagement with the auxiliary component. The shell cover 80 also has a protective component locking portion for installing or removing the protective component. This locking portion may include, for example, at least two lateral hooks 84. Each lateral hook 84 may include a hook body 84a extending upwards from the center of the bottom surface of the shell cover 80. The top end of the extended portion of the hook body 84a has a radially inwardly protruding hook portion 84b, the radially inwardly protruding end face of which abuts against the side of the protective shell. The radially inner end face of the hook portion 84b may be configured to match the shape of the radially outer peripheral surface of the protective shell for better positioning.

[0078] In some embodiments, the circumferential side portion of the protective shell 30 is further provided with a radially extending positioning plane, which can abut against the positioning side 84d of the hook portion 84b, so that the protective shell 30 can be clamped by the hook portion 84b in at least a unidirectional anti-rotation manner. Those skilled in the art will understand that although a positioning plane extending radially along the circumferential side portion of the protective shell 30 has been described above, this disclosure does not limit the form of the positioning structure on the outer side of the protective shell 30. For example, in some embodiments, the positioning plane can also be configured to form a certain angle with the radial direction; for example, it can be inclined toward the circumferential outer surface of the protective shell 30. Correspondingly, the positioning side 84d of the hook portion 84b of the shell cover 80 can also form a certain angle with the radial direction, and the inclination angles of the positioning plane and the positioning side 84d can match each other. Therefore, for example, when the positioning side 84d of the hook portion 84b rotates and engages with the positioning plane, the lateral corner of the hook portion 84d can at least partially rotate and move into the angled space formed by the positioning plane and other side portions of the protective shell 30, forming a ratchet-pawl type engagement. Thus, the positioning side 84d and the positioning plane can form a self-locking mechanism, preventing the lateral hook 84 from deforming and disengaging when subjected to excessive force.

[0079] According to some embodiments of this disclosure, the monitoring device applicator, with the aid of a first elastic locking mechanism 30 and a second elastic locking mechanism 40 triggered by its action, can efficiently and quickly apply the detection device with simple operation, reducing the risk of medical accidents caused by improper use by the patient.

[0080] See Figure 8 , Figure 8An exemplary cross-sectional view of a detection system according to some embodiments of this disclosure is shown. In some embodiments, the detection system 200 includes a detection device applicator 100 and a detection device assembly 70 according to various embodiments of this disclosure. The detection device assembly 70 may include, for example, a detection device 71, an auxiliary assembly 72 disposed above the detection device 71, and a protective assembly 73 disposed below the detection device 71. In some embodiments, the detection device assembly 70 may include the detection device 71 as described in various embodiments of this disclosure. The detection device 71 may be, for example, an electronic device for installation on the human body and for detecting various analytes on the human body, such as analyzing tissue fluid of the human body to collect indicators including but not limited to glucose, blood glucose, acetylcholine, amylase, bilirubin, cholesterol, human chorionic gonadotropin, creatine kinase (e.g., CK-MB), creatine, DNA, fructosamine, glucose, glutamine, growth hormone, hormones, ketones (e.g., ketone bodies), lactate, oxygen, peroxides, prostate-specific antigen, prothrombin, RNA, thyroid-stimulating hormone, and troponin. The concentration of the drug can also be determined, and the drug is such as, but not limited to, antibiotics (e.g., gentamicin, vancomycin, etc.), digoxin, anesthetics, theophylline, and warfarin. The detection device 71 may include, for example, a housing and electronic components, wherein the electronic components may be disposed within the housing. The housing may have a housing channel extending vertically through the housing, and the electronic components may include a detection needle extending vertically downward and protruding from the housing. The detection needle may be used, for example, to insert into the human body to detect corresponding physiological indicators within the body.

[0081] See also: Figure 9 , Figure 9 An exemplary exploded view of a detection device assembly of a detection system according to some embodiments of this disclosure is shown. The detection device assembly 70 may further include a needle assist assembly, which may include an auxiliary component 72 and a protective component 73 as described in various embodiments of this disclosure. The auxiliary component 72 may be vertically disposed on the upper side of the housing, and the protective component 73 may include a protective shell disposed on the lower side of the housing. The auxiliary component 72 may, for example, include a puncture needle for assisting the detection needle in piercing the human body. The protective component 73 is used to surround and seal the puncture needle and the detection needle to seal and protect them from environmental contamination. The auxiliary component 72 and the protective component 73 may engage within a housing aperture of the housing and are rotatable relative to each other to a locked position or an unlocked position. In the locked position, the auxiliary component 72 and the protective component 73 are vertically limited by the housing.

[0082] In some embodiments, the auxiliary component 72 includes a generally columnar needle holder, one axial end of which is fixedly connected to the puncture needle, and a radially inwardly recessed locking groove near the other axial end. The locking groove engages with the tip of the return latch 413 of the return sleeve 41, so that the auxiliary component 72 can be pulled out relative to the detection device 71 when the return sleeve 41 moves radially away from the delivery platform 313. In some embodiments, when the auxiliary component 72 and the protective component 73 are locked relative to each other, the lower end face of the needle holder is flush with the lower end face of the detection device 71, or recessed inward relative to the lower end face, so that the needle holder does not obstruct the insertion of the puncture needle when the detection device component is applied to the human body, and there is no need to remove the needle in advance.

[0083] The working process of the detection system is explained below with reference to the accompanying drawings.

[0084] See Figure 10 , Figure 10 An exemplary cross-sectional view of a detection system according to some embodiments of this disclosure is shown, wherein the detection system is in an initial state. In some embodiments, when the detection system is not in use, the detection device 71 of the detection device assembly 70 is located below the second platform 314 of the first elastic locking mechanism 30, the needle seat of the auxiliary assembly 72 is locked above the second platform 314 by the return latch 413 of the return sleeve 41, the protective shell of the protective assembly 73 is held below the detection device 71 by the lateral hook 84 of the shell cover 80, and the protective shell and the needle seat are engaged opposite each other inside the housing channel of the detection device 71 and locked relative to each other in the vertical direction. The delivery mechanism of the detection device applicator is locked in the delivery holding position by the first locking part of the abutment 20, and the return mechanism of the detection device applicator is locked in the return holding position by the second locking part of the abutment 20. At this time, the first spring 32 can be compressed to provide spring pressure to press against the delivery sleeve 31 in the vertical direction. However, it can only be partially compressed at this time, so that it can be kept in a state of incomplete compression before the detection system is used, thus avoiding creep due to long-term high compression.

[0085] See Figure 11 , Figure 11An exemplary cross-sectional view of a detection system according to some embodiments of this disclosure is shown, illustrating the state in which the protective shell and needle seat are unlocked and removed after the shell cover 80 of the detection system is rotated. After the shell cover 80 is screwed relative to the abutment 20, the locking block 83 of the shell cover 80 rotates and moves along the locking positioning groove 262 at the bottom of the abutment 20, and is eventually able to move vertically out of the locking groove 261 at the bottom of the abutment 20. At the same time, the positioning side 84d of the lateral hook 84 of the shell cover 80 can abut against the positioning plane of the protective shell, so that the protective shell rotates together with the shell cover 80 until it rotates to an unlocked position relative to the auxiliary component 72, at which point the protective shell can be moved downward relative to the auxiliary component 72 in the vertical direction. The radial end face of the hook portion 84b of the lateral hook 84 of the shell cover 80 can ensure that the protective shell remains vertical during rotation by means of its shape matching with the side of the protective seat, reducing the risk of rotational obstruction due to the protective shell being tilted.

[0086] See Figure 12 , Figure 12 An exemplary cross-sectional view of a detection system according to some embodiments of this disclosure is shown, illustrating the state of the first resilient locking mechanism 30 when it is unlocked after pressing the housing 10 relative to the abutment 20. After removing the cover 80, the lower surface of the applicator abutment 20 can be brought into contact with the target position on the human body intended for placing the detection device 71, and the housing 10 can be pressed relative to the abutment 20. At this time, the housing 10 moves downward relative to the abutment 20, and the housing clearance hole 101 of the housing 10 moves to align with the radial stop 202a of the abutment 20. The radial stop 202a extends radially into the housing clearance hole 101 under the push of the push top 31a of the delivery sleeve 31 in its radial interior, such that the locking drive block 202b on the radial interior side of the abutment 20 simultaneously moves radially outward to avoid the delivery sleeve 31, allowing the delivery sleeve 31 to move downward in the vertical direction.

[0087] By configuring the housing 10 to move relative to the abutment 20 in the application direction toward the detection device 71 and placing the detection device 71 there, the user's pressing direction during use can be aligned with the location of the skin to be tested, making the application operation simpler and more direct. Simultaneously, since the housing 10 can be configured as an outer shell exposed on the side away from the skin to be tested relative to the abutment 20, it can serve as a handle for the user to hold stably, facilitating the application of force.

[0088] See Figure 13 , Figure 13An exemplary cross-sectional view of the detection system according to some embodiments of this disclosure is shown, illustrating the state when the second elastic locking mechanism 40 is unlocked after the delivery sleeve 31 has extended. After the first elastic locking mechanism is unlocked, the delivery sleeve 31 moves vertically downward under the spring force of the first spring 32, pushing against the detection device 71, causing the puncture needle-assisted detection needle to pierce the human body, and the lower surface of the detection device 71 is in contact with the human body. When the detection device 71 moves vertically to the installation position, the top ends of the outer surfaces of the plurality of elastic locking hooks 313b on the delivery platform 313 disengage from the sidewall of the trigger cylinder 107. This allows the plurality of elastic locking hooks 313b to deform radially outward under the action of the second spring 42 by means of the contact between their hook head inclined surface 313e and the unlocking inclined surface 414 of the return sleeve 41, thereby releasing the return sleeve 41 vertically.

[0089] See Figure 14 , Figure 14 An exemplary cross-sectional view of the detection system according to some embodiments of this disclosure is shown. It illustrates the state of the detection device 71 after retraction. After the second elastic locking mechanism 40 is released, the retraction sleeve 41 and the auxiliary component 72 fixedly connected thereto move vertically upward under the push of the second spring 42, thereby pulling the puncture needle out of the body. The retraction sleeve 41 can continue to move until the tip of the puncture needle is completely retracted into the upper side of the second platform 314, so that the puncture needle is not exposed. At this time, the check surface 31c provided on the delivery sleeve 31 can abut against the lower end face of the locking drive block 202b on the abutment member 20, thereby preventing the delivery sleeve 31 from rebounding after the application device is used, and avoiding accidental upward pressing of the delivery sleeve 31 by the user after using the application device, which could expose the puncture needle and cause the user to be pricked by the needle tip. In some embodiments, an upward-facing check surface 101a may also be provided on the lower side of the housing clearance hole 101. After the elastic arm 202 moves toward the housing clearance hole 101 to release the delivery mechanism, the radially inner side of the elastic arm 202 is abutted radially outward by the delivery mechanism and extends into the housing clearance hole 101. At this point, the check surface 101a abuts against the bottom end of the radial stop 202a of the elastic arm 202 to prevent the housing 10 from moving in the opposite direction. This serves as a notification to the user that the detection system is in use, preventing confusion with unused detection systems.

[0090] Therefore, the detection system according to some embodiments of this disclosure can automatically apply the detection device. When the detection device needs to be inserted into the human body using a needle or other mechanism, the detection system with automatic application function can reduce the user's psychological stress and actual pain by achieving automatic and rapid return, and can avoid problems such as insufficient needle depth or misalignment caused by improper operation, thereby improving the success rate of detection device installation.

[0091] While numerous embodiments of this disclosure have been shown and described herein, it will be apparent to those skilled in the art that such embodiments are provided by way of example only. Many modifications, alterations, and alternatives will occur to those skilled in the art without departing from the spirit and intent of this disclosure. It should be understood that various alternatives to the embodiments of this disclosure described herein may be employed in the practice of this disclosure. The appended claims are intended to define the scope of this disclosure and therefore cover equivalents or alternatives within the scope of these claims.
