Moreover, the specific features, structures, materials or characteristics described can be combined in any appropriate manner in any one or more embodiments or examples.
[0041] Referring to FIGS. 1-7, a micro-sensor implanting device is disclosed, which comprises a data acquisition unit 1, an electronic unit 2 and an implanting unit 3, wherein the data acquisition unit 1 is configured to acquire monitoring data capable of representing the concentration of an analyte; the electronic unit 2 is configured to transmit the monitoring data, and the electronic unit 2 has a rechargeable battery; and the implanting unit 3 is configured to implant the data acquisition unit 1 partially into the subcutaneous tissue of a living body, and the implanting unit 3 comprises a housing 31 and a charging assembly 32 arranged on the housing 31, and the charging assembly 32 is configured to charge the battery.
[0042] It can be understood that the data acquisition unit 1 can be electrically connected with the electronic unit 2 to transmit the monitoring data to the electronic unit 2.
[0043] Since the electronic unit 2 in the application has a rechargeable battery, and the implanted unit 3 comprises a charging assembly 32 arranged in the shell 31 and used for charging the battery, that is, the charging assembly 32 is integrated in the implanted unit 3, thereby reducing the number of additional components required by the miniature sensor implant device, and for not needing to purchase and keep multiple components, reducing the use cost of the user and improving the use convenience of the user.
[0044] At the same time, the user can use the charging assembly 32 to charge the battery of the electronic unit 2 before using the miniature sensor implant device, so that the battery of the electronic unit 2 can be in a full power state when the user uses the miniature sensor implant device, to avoid the situation that the effective monitoring time of the electronic unit 2 is affected due to the low battery power caused by the long storage time of the miniature sensor implant device, thereby ensuring the effective monitoring time of the electronic unit 2, and further improving the use experience of the user.
[0045] In addition, for the scheme that the electronic unit 2 is assembled in the shell 31 when leaving the factory, the charging assembly 32 in the application can directly charge the battery of the electronic unit 2 to achieve the effect of conveniently supplementing the battery of the electronic unit 2, to ensure the effective monitoring time of the electronic unit 2, and further ensure the use experience of the user.
[0046] The charging position of the electronic unit 2 in the application is not specifically limited, and any one of the following embodiments can be adopted:
[0047] Embodiment one, in this embodiment, the implanted unit 3 further comprises a pushing assembly 34 used for driving the data acquisition unit 1 to move, and the shell 31 is internally provided with a mounting position located below the pushing assembly 34, and the charging assembly 32 is configured to charge the electronic unit 2 when the electronic unit 2 is in the mounting position.
[0048] Specifically, the charging assembly 32 is located at the periphery or top of the mounting position.
[0049] It can be understood that when the miniature sensor implant device leaves the factory, the electronic unit 2 is assembled in the mounting position, and since the charging assembly 32 is located at the periphery or top of the mounting position, the charging assembly 32 can charge the battery of the electronic unit 2 when the electronic unit 2 is in the mounting position, thereby avoiding the situation that the electronic unit 2 needs to be taken out of the mounting position when charging the electronic unit 2, to achieve the effect of conveniently charging the electronic unit 2 assembled in the mounting position, and further improve the use experience of the user.
[0050] In the second embodiment, the implanting unit 3 further comprises a pushing assembly 34 for driving the data acquisition unit 1 to move, the charging assembly 32 comprises a charging position 321 located above the pushing assembly 34, and the charging assembly 32 is configured to charge the battery of the electronic unit 2 when the electronic unit 2 is placed in the charging position 321.
[0051] It can be understood that the charging position 321 and the mounting position are two different workstations, and the electronic unit 2 can be assembled in the charging position 321 when the micro-sensor implanting device is shipped, so as to facilitate the battery of the electronic unit 2 to be charged.
[0052] Since the charging assembly 32 is arranged on the top of the pushing assembly 34, the charging assembly 32 is avoided from the mounting position, so as to ensure the smoothness of implanting the data acquisition unit 1, and the structure of the micro-sensor implanting device is more reasonable, so as to facilitate the miniaturization design of the micro-sensor implanting device.
[0053] Further, referring to FIGS. 1, 2 and 3, the charging position 321 is located on the top of the shell 31 and penetrates the shell 31 upward, and the charging assembly 32 further comprises a charging module 322 arranged at the bottom or the side of the charging position 321.
[0054] Since the charging position 321 is located on the top of the shell 31, when charging the battery of the electronic unit 2, the electronic unit 2 only needs to be placed on the top of the shell 31, so as to facilitate the charging of the battery of the electronic unit 2, and the shell 31 can be kept in an upright state when charging the battery of the electronic unit 2, so as to increase the stability of the shell 31 when charging the battery of the electronic unit 2, to avoid the situation that the user is frightened due to the rolling of the shell 31, and further improve the user experience. Since the charging position 321 penetrates the shell 31 upward, the charging position 321 forms a space for accommodating the electronic unit 2, so as to increase the stability of the electronic unit 2 assembled in the mounting position 321.
[0055] Preferably, referring to FIGS. 2 and 3, the top of the shell 31 is provided with a mounting cavity 311, the mounting cavity 311 is located at the bottom of the charging position 321, and at least part of the structure of the charging module 322 is located in the mounting cavity 311, so that the charging module 322 is isolated from the outside, to avoid the possibility that the liquid in the outside causes the charging module 322 to be short-circuited, to ensure the service life of the charging module 322, and to increase the safety of the charging module 322.
[0056] The structure of the charging module 322 is not limited in the present application. Preferably, the charging module 322 comprises a circuit board, a charging interface electrically connected to the circuit board, and a conductive part electrically connected to the circuit board. The battery has a conductive part capable of being electrically connected to the conductive part. When charging the battery, the electronic unit 2 is placed in the charging position 321 so that the conductive part is electrically connected to the conductive part. Then, the additional power line is connected to the charging interface to charge the battery. In other embodiments, a supplemental battery can be added based on the above-mentioned embodiments to charge the battery of the electronic unit 2, and the power line is electrically connected to the charging interface to charge the supplemental battery.
[0057] The structure of the conductive part and the conductive part is not limited in the present application. Preferably, the conductive part is a block structure made of metal material, and the conductive part is also a block structure made of metal material, so that the conductive part and the conductive part can be electrically connected when they are in contact. The metal material is preferably copper, and it can also be other materials with conductive properties such as iron. In other embodiments, the conductive part can also be an electromagnetic coil, and the conductive part is also an electromagnetic coil to achieve wireless charging of the battery.
[0058] In the third embodiment, the implant unit 3 further comprises a pushing assembly 34 for driving the data acquisition unit 1 to move, the charging assembly 32 comprises a charging position 321 arranged on the shell 31 and located on the side of the pushing assembly 34, and a charging module 322 located on the side of the charging position 321. The charging assembly 32 is configured to charge the electronic unit 2 when the electronic unit 2 is in the charging position 321, so as to reduce the height of the shell 31, thereby achieving the effect of facilitating the storage of the miniature sensor implant device.
[0059] The assembly method of the data acquisition unit 1 and the electronic unit 2 when the data acquisition unit 1 is implanted into the subcutaneous tissue is not limited in the present application. It can be that the data acquisition unit 1 is assembled on the electronic unit 2 first, and then the data acquisition unit 1 is implanted; or the data acquisition unit 1 is implanted into the subcutaneous tissue first, and then the electronic unit 2 is assembled on the data acquisition unit 1; or the data acquisition unit 1 is assembled on the electronic unit 2 during the process of implanting the data acquisition unit 1 into the subcutaneous tissue.
[0060] The structure of the implant unit 3 is not limited in the present application, which can adopt any of the following embodiments:
[0061] In the first embodiment, the implant unit 3 further comprises a connecting seat, a pushing assembly 34, and a puncture assembly 35 fixedly connected to the connecting seat. The pushing assembly 34 is used to push the connecting seat to move, so that the connecting seat drives the puncture assembly 35 to move in the first direction to complete the implantation action.
[0062] Since the puncture assembly 35 is fixedly connected with the connecting seat in the embodiment, the puncture assembly 35 cannot be disassembled, that is, the entire implant unit 3 can be used only once.
[0063] It should be noted that the bottom of the shell 31 has an implantation port, and the first direction in the present application is determined according to the direction of the implantation port, that is, the direction of the inside of the shell 31 along the axial direction close to the implantation port is the first direction, and the second direction is the reverse direction of the first direction.
[0064] In the second embodiment, referring to FIGS. 2 and 3, the implant unit 3 further comprises a clamping piece 33, a pushing assembly 34, and a puncture assembly 35 detachably connected with the clamping piece 33, and the pushing assembly 34 is used to push the clamping piece 33 and the puncture assembly 35 to move along the first direction to complete the implantation action.
[0065] Since the puncture assembly 35 is detachably connected with the clamping piece 33, the used puncture assembly 35 can be replaced, so that other parts of the implant unit 3 can be repeatedly used, thereby reducing the use cost of the user, and achieving the effect of saving resources.
[0066] In a preferred embodiment, the clamping piece 33 has a target position, an initial position above the target position, and a release position below the target position, and the clamping piece 33 can clamp and fix the puncture assembly 35 when it is in the target position or the initial position, and the clamping piece 33 releases the puncture assembly 35 when it is in the release position.
[0067] Specifically, when disassembling the puncture assembly 35, the puncture assembly 35 is pulled downward, so that the puncture assembly 35 drives the clamping piece 33 to move, so that the clamping piece 33 moves to the release position, and the clamping piece 33 releases the puncture assembly 35 to complete the disassembly of the puncture assembly 35; when installing the puncture assembly 35, the puncture assembly 35 is aligned with the clamping piece 33 first, and then the puncture assembly 35 is pushed upward, so that the puncture assembly 35 pushes the clamping piece 33 to move to the initial position, and the clamping piece 33 clamps and fixes the puncture assembly 35 to complete the installation of the puncture assembly 35. In summary, when disassembling and assembling the puncture assembly 35, only the puncture assembly 35 needs to be driven in the vertical direction, thereby reducing the difficulty of disassembling and assembling the puncture assembly 35, thereby improving the user's use experience, and improving the disassembling and assembling efficiency of the puncture assembly 35.
[0068] The structure of the clamping piece 33 is not limited in the present application, and any one of the following embodiments can be adopted:
[0069] In the embodiment, referring to FIGS. 2 and 3, the pushing assembly 34 comprises a sleeve 341 and an elastic member 342 acting on the sleeve 341, and the piercing assembly 35 is moved in the second direction to be mounted to the clamping member 33, and the piercing assembly 35 is moved in the second direction to push the sleeve 341 to compress the elastic member 342.
[0070] Since the piercing assembly 35 is moved in the second direction to be mounted to the clamping member 33, the piercing assembly 35 is moved in the second direction to push the sleeve 341 to compress the elastic member 342, so that the piercing assembly 35 is mounted and the elastic member 342 is charged at the same time, thereby reducing the operation steps required when using the micro-sensor implanting device, and further improving the user experience.
[0071] Further, referring to FIGS. 2, 3, 4 and 5, the sleeve 341 is provided with a guide portion 343 extending in the first direction, the guide portion 343 is provided with a receiving groove 344, the housing 31 is provided with a guide rib 312 in the receiving groove 344 for sliding abutment with the clamping member 33, the guide rib 312 is provided with an avoiding gap 313, the clamping member 33 comprises a clamping portion 331 for clamping the piercing assembly 35, when the clamping portion 331 is out of position with the avoiding gap 313, the clamping portion 331 can clamp and fix the piercing assembly 35, and when the clamping portion 331 is opposite to the avoiding gap 313, the clamping portion 331 is offset to the avoiding gap 313 to release the piercing assembly 35.
[0072] That is, the avoiding gap 313 is located at the bottom of the guide rib 312, the clamping portion 331 is elastic, when the clamping portion 331 is out of position with the avoiding gap 313, the clamping portion 331 is deformed under the action of the guide rib 312 to be able to clamp and fix the piercing assembly 35, and when the clamping portion 331 is opposite to the avoiding gap 313, the clamping portion 331 restores deformation under the action of its own elasticity and is offset to the avoiding gap 313, so that the clamping portion 331 is separated from the piercing assembly 35 to release the piercing assembly 35.
[0073] Specifically, when the puncture assembly 35 is disassembled, the puncture assembly 35 is pulled in the first direction, and then the puncture assembly 35 drives the clamping piece 33 to move in the first direction, at this time the clamping part 331 slides relative to the guide ribs 312, and when the clamping part 331 moves to the position of the avoiding gap 313, that is, the clamping part 331 is opposite to the avoiding gap 313, the clamping part 331 is offset into the avoiding gap 313 under the action of its own elasticity, so that the clamping part 331 releases the puncture assembly 35, to complete the disassembly of the puncture assembly 35; when the puncture assembly 35 is installed, the puncture assembly 35 is aligned with the clamping piece 33 first, and then the puncture assembly 35 is pushed in the second direction, and then the puncture assembly 35 drives the clamping piece 33 to move in the second direction, so that the clamping part 331 gradually dislocates from the avoiding gap 313 and cooperates with the guide ribs 312, so that the clamping part 331 is offset to the inside of the guide part 343 under the action of the guide ribs 312 and clamped on the puncture assembly 35, to complete the installation of the puncture assembly 35, and then the clamping piece 33 realizes the clamping and releasing of the puncture assembly 35.
[0074] The structure of the guide part 343 is not limited in the application, preferably, the guide part 343 is a circular tube structure provided in the sleeve 341 and the top end is closed, so that the guide part 343 can guide the clamping piece 33 and increase the clamping stability of the clamping piece 33 on the puncture assembly 35. In other embodiments, the guide part 343 can also have other structures, as long as it can accommodate the clamping piece 33.
[0075] Further, the clamping piece 33 further comprises a limiting part 332 capable of cooperating with the sleeve 341, the limiting part 332 has a guide surface 334 capable of cooperating with the guide rib 312, and the guide rib 312 is configured to press the guide surface 334 to make the limiting part 332 disengage from the sleeve 341 in the first direction.
[0076] It can be understood that the limiting part 332 also has elasticity and can be stopped in the first direction with the sleeve 341, and when the limiting part 332 is stopped in the first direction with the sleeve 341, the sleeve 341 presses the clamping piece 33 in the first direction to make the clamping piece 33 move synchronously with the sleeve 341, so that the guide surface 334 gradually approaches the guide rib 312; when the guide surface 334 abuts against the guide rib 312, the guide rib 312 applies an inward extrusion force to the guide surface 334, so that the limiting part 332 disengages from the sleeve 341 in the first direction, and then the clamping piece 33 can move relative to the sleeve 341 in the second direction.
[0077] Specifically, the clamping piece 33 has a target position and a needle withdrawing position above the target position, when the clamping piece 33 moves to the target position, the guide surface 334 cooperates with the guide rib 312 to make the limiting part 332 deform and unblock the sleeve 341, so that the clamping piece 33 can move in the second direction and move to the needle withdrawing position to complete the needle withdrawing action.
[0078] Preferably, the side of the limiting part 332 away from the center of the guide part 343 is sharp to ensure that the limiting part 332 can deform and block the sleeve 341 when it moves to the accommodating groove 334.
[0079] Preferably, referring to FIGS. 2, 3 and 6, the clamping piece 33 further includes a connecting part 333 between the clamping part 331 and the limiting part 332, the clamping part 331 and the limiting part 332 are connected to the connecting part 333, and the connecting part 333 has a blocking wall capable of blocking the puncture assembly 35 in the second direction to ensure that the clamping piece 33 can move in the second direction along with the puncture assembly 35 when the puncture assembly 35 is installed in the second direction.
[0080] The number and structure of the clamping part 331 are not limited in the application, preferably, referring to FIG. 5, a plurality of clamping parts 331 are arranged along the circumference of the connecting part 333 to increase the clamping points of the puncture assembly 35 and further increase the clamping stability of the puncture assembly 35; and the clamping part 331 is an L-shaped structure in vertical section to further increase the clamping stability of the puncture assembly 35. In other embodiments, the clamping part 331 can also be provided with only one, and the clamping part 331 can also be other structures as long as it can clamp and fix the puncture assembly 35.

When implanting the data acquisition unit 1, the locking block 346 is pressed towards the inside of the shell 31 to deform the elastic arm 345, so that the locking block 346 is in stop cooperation with the wall of the stop opening 314, so that the sleeve 341 moves in the first direction under the action of the elastic member 342, and then the clamping member 33 moves to the target position to complete the implantation action.

[0096] It can be understood that the clamping portion 331 is elastic, so that when the puncture assembly 35 is installed along the second direction, the puncture assembly 35 pushes the clamping member 33 to move along the second direction, so that the clamping portion 331 is gradually misaligned with the avoiding slot and cooperates with the inner wall of the guide portion 343, thereby causing the clamping portion 331 to deform under the action of the guide portion 343 to clamp and fix the puncture assembly 35; when the clamping portion 331 moves to the position of the avoiding slot, the clamping portion 331 deforms towards the outside of the guide portion 343 through the avoiding slot under the action of its own elasticity to release the puncture assembly 35.

[0100] The structure of the driving piece is not limited in the application, preferably, the driving piece is a spring, so as to ensure the elastic driving effect of the driving piece on the limiting block. In other embodiments, the driving piece can also be an elastic sheet or an elastic column or other structures capable of applying elastic force to the limiting block.
