Abstract
Description
Technical Field
[0001] This application belongs to the technical field of medical devices, specifically relating to a continuous analyte concentration monitoring device. Background Technology
[0002] CGM (Continuous Glucose Monitoring) is a technology that indirectly reflects blood glucose levels by continuously monitoring the glucose concentration in subcutaneous tissue fluid using a glucose sensor. CGM products require a needle and sensor pin to puncture the skin. The sensor's enzymes react with the subcutaneous tissue fluid in an electrochemical reaction, generating an electrical signal, which is then converted into blood glucose data for the user.
[0003] Continuous glucose monitoring (CGM) devices typically include a sensor and an electronic unit (transmitter) electrically connected to the sensor. The electronic unit is battery-powered. However, batteries have limited capacity, and after months of storage, their energy is almost completely depleted, thus affecting the effective monitoring time of online glucose monitoring devices. Existing solutions for improving the effective monitoring time of CGM devices are costly and complex to implement. Furthermore, for products where the electronic unit is pre-installed in the syringe, current solutions cannot recharge the battery. Summary of the Invention

[0035] Many specific details are set forth in the following description to provide a thorough understanding of this application.

[0039] Reference Figures 1 to 7 A continuous analyte concentration monitoring device is disclosed, comprising a data acquisition unit 1, an electronic unit 2, and an implantation unit 3. The data acquisition unit 1 is used to acquire monitoring data that can characterize the concentration of the analyte; the electronic unit 2 is used to transmit the monitoring data and has a rechargeable battery; the implantation unit 3 is used to partially implant the data acquisition unit 1 into the subcutaneous tissue of an organism. The implantation unit 3 includes a housing 31 and a charging component 32 disposed on the housing 31, the charging component 32 being used to charge the battery.
[0040] Understandably, the data acquisition unit 1 can be electrically connected to the electronic unit 2 to transmit monitoring data to the electronic unit 2.
[0041] Since the electronic unit 2 in this application has a rechargeable battery, and the implanted unit 3 includes a charging component 32 disposed in the housing 31 for charging the battery, that is, the charging component 32 is integrated into the implanted unit 3, thereby reducing the number of additional components required for the continuous analyte concentration monitoring device, and eliminating the need to purchase and retain multiple components, reducing the user's operating costs and improving the user's ease of use.
[0042] Meanwhile, the charging component 32 allows users to charge the battery of the electronic unit 2 before using the continuous analyte concentration monitoring device, ensuring that the battery of the electronic unit 2 is fully charged when the user uses the continuous analyte concentration monitoring device. This avoids the situation where the battery power is low due to the long storage time of the continuous analyte concentration monitoring device, which affects the effective monitoring time of the electronic unit 2, thereby ensuring the effective monitoring time of the electronic unit 2 and improving the user experience.
[0043] In addition, for the solution where the electronic unit 2 is assembled into the housing 31 at the factory, the charging component 32 in this application can directly charge the battery of the electronic unit 2, so as to facilitate the replenishment of the battery of the electronic unit 2, thereby ensuring the effective monitoring time of the electronic unit 2 and thus ensuring the user's user experience.
[0044] This application does not specifically limit the charging position of electronic unit 2, which can be implemented in any of the following embodiments:
[0045] In this embodiment, the implanted unit 3 further includes a pushing component 34 for driving the data acquisition unit 1 to move. The housing 31 has an installation position located below the pushing component 34. The charging component 32 is configured to charge the electronic unit 2 when the electronic unit 2 is in the installation position.
[0046] Specifically, the charging component 32 is located on the periphery or top of the mounting position.
[0047] Understandably, when the continuous analyte concentration monitoring device leaves the factory, the electronic unit 2 is installed in the mounting position. Since the charging component 32 is located on the periphery or top of the mounting position, the charging component 32 can charge the battery of the electronic unit 2 when the electronic unit 2 is in the mounting position. This avoids the need to remove the electronic unit 2 from the mounting position when charging, thus facilitating the charging of the electronic unit 2 installed in the mounting position and further improving the user experience.
[0048] In the second embodiment, the implanted unit 3 further includes a pushing component 34 for driving the data acquisition unit 1 to move, and a charging component 32 includes a charging position 321 located above the pushing component 34. The charging component 32 is configured to charge the battery of the electronic unit 2 when the electronic unit 2 is placed in the charging position 321.
[0049] It is understandable that the charging position 321 and the installation position are two different work positions. When the continuous analyzer concentration monitoring device leaves the factory, the electronic unit 2 can also be assembled in the charging position 321 to facilitate the replenishment of power to the battery of the electronic unit 2.
[0050] Since the charging component 32 is located on top of the pushing component 34, the charging component 32 avoids the mounting position, ensuring smooth implantation of the data acquisition unit 1. At the same time, it makes the structural layout of the continuous analyte concentration monitoring device more reasonable, thereby facilitating the miniaturization design of the continuous analyte concentration monitoring device.
[0051] Furthermore, refer to Figure 1 , Figure 2 and Figure 3 The charging position 321 is located at the top of the housing 31 and extends upward through the housing 31. The charging assembly 32 also includes a charging module 322 located at the bottom or around the charging position 321.
[0052] Since the charging position 321 is located at the top of the housing 31, when charging the battery of the electronic unit 2, it is only necessary to place the electronic unit 2 on top of the housing 31, which facilitates charging the battery of the electronic unit 2. Furthermore, charging the battery of the electronic unit 2 allows the housing 31 to remain upright, increasing its stability during charging and preventing any panic caused by the housing 31 rolling, thus further improving the user experience. Moreover, since the charging position 321 extends upward through the housing 31, it forms a space to accommodate the electronic unit 2, increasing the stability of the electronic unit 2 assembled in the charging position 321.
[0053] The better one is to refer to Figure 2 and Figure 3 The top of the housing 31 is provided with a mounting cavity 311, which is located at the bottom of the charging position 321. At least part of the structure of the charging module 322 is located in the mounting cavity 311, thereby isolating the charging module 322 from the outside world to prevent the charging module 322 from being short-circuited by external liquids, so as to ensure the service life of the charging module 322 and increase the safety of the charging module 322.
[0054] This application does not specifically limit the structure of the charging module 322. Preferably, the charging module 322 includes 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 that can be 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, an additional power line is connected to the charging interface to charge the battery. In other embodiments, a replenishing battery can be added based on the above embodiments so that the replenishing battery charges the battery of the electronic unit 2, and the power line is electrically connected to the charging interface to charge the replenishing battery.
[0055] This application does not specifically limit the structure of the conductive part and the conductive part. Preferably, the conductive part is a block structure made of a metal material, and the conductive part is also a block structure made of a metal material, so that the conductive part and the conductive part can conduct electricity when they come into contact. The metal material is preferably copper, but it can also be iron or other materials with conductive properties. In other embodiments, the conductive part can also be an electromagnetic coil, and the conductive part can also be an electromagnetic coil, to realize wireless charging of the battery.
[0056] In the third embodiment, the implanted unit 3 further includes a pushing component 34 for driving the data acquisition unit 1 to move. The charging component 32 includes a charging position 321 disposed on the housing 31 and located on the side of the pushing component 34, and a charging module 322 located on the side of the charging position 321. The charging component 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 housing 31 and achieve the effect of facilitating the storage of the continuous analyte concentration monitoring device.
[0057] This application does not specify 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. It can be that the data acquisition unit 1 is assembled into 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 and then the electronic unit 2 is assembled into the data acquisition unit 1; or the data acquisition unit 1 is assembled into the electronic unit 2 during the process of implanting the data acquisition unit 1 into the subcutaneous tissue.
[0058] This application does not impose specific limitations on the structure of the implantation unit 3, which can adopt any of the following embodiments:
[0059] In this embodiment, the implantation unit 3 further includes a connector, a pushing component 34, and a puncture component 35 fixedly connected to the connector. The pushing component 34 is used to push the connector to move so that the connector drives the puncture component 35 to move along a first direction to complete the implantation action.
[0060] Since the puncture component 35 is fixedly connected to the connector in the embodiment, the puncture component 35 cannot be disassembled. In other words, the entire implantation unit 3 can only be used once.
[0061] It should be noted that the bottom of the housing 31 has an implantation port. The first direction mentioned in this application is determined according to the direction of the implantation port. That is, the direction of the interior of the housing 31 along its axial direction close to the implantation port is the first direction, while the second direction is the opposite of the first direction.
[0062] Implementation Method Two: In this implementation method, refer to... Figure 2 and Figure 3The implantation unit 3 also includes a clamping member 33, a pushing component 34, and a puncture component 35 detachably connected to the clamping member 33. The pushing component 34 is used to push the clamping member 33 and the puncture component 35 to move along a first direction to complete the implantation action.
[0063] Since the puncture assembly 35 and the clamping member 33 are detachably connected, the puncture assembly 35 can be replaced after use, so that other parts of the implantation unit 3 can be reused, thereby reducing the user's operating costs and achieving the effect of saving resources.
[0064] In a preferred embodiment, the clamping member 33 has a target position, an initial position above the target position, and a release position below the target position. When the clamping member 33 is in the target position or the initial position, it can clamp and fix the puncture component 35. When the clamping member 33 is in the release position, it releases the puncture component 35.
[0065] Specifically, when disassembling the puncture component 35, pull the puncture component 35 downwards, causing it to move the clamping member 33 to the release position. At this point, the clamping member 33 releases the puncture component 35, completing the disassembly. When installing the puncture component 35, first align the puncture component 35 with the clamping member 33, then push the puncture component 35 upwards until the clamping member 33 returns to its initial position. The clamping member 33 then holds and secures the puncture component 35, completing the installation. In summary, disassembling and assembling the puncture component 35 only requires driving it vertically, reducing the difficulty of disassembly and assembly, improving the user experience, and increasing the efficiency of disassembly and assembly.
[0066] This application does not specifically limit the structure of the clamping member 33, which can adopt any of the following embodiments:
[0067] Example 1, in this example, refers to Figure 2 and Figure 3 The pushing component 34 includes a sleeve 341 and an elastic element 342 acting on the sleeve 341. The piercing component 35 moves in a second direction to be installed on the clamping component 33. The piercing component 35 moves in the second direction to push the sleeve 341 to compress the elastic element 342.
[0068] As the puncture assembly 35 moves along the second direction to be installed onto the clamping member 33, the movement of the puncture assembly 35 along the second direction pushes the sleeve 341 to move along the second direction to compress the elastic member 342. This achieves the simultaneous installation of the puncture assembly 35 and the storage of force on the elastic member 342, thereby reducing the number of operation steps required when using the continuous analyte concentration monitoring device and further improving the user experience.
[0069] Furthermore, refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 The sleeve 341 is provided with a guide portion 343 extending along a first direction. The guide portion 343 is provided with a receiving groove 344. The housing 31 is provided with a guide rib 312 located in the receiving groove 344 for sliding contact with the clamping member 33. The guide rib 312 is provided with an avoidance notch 313. The clamping member 33 includes a clamping portion 331 for clamping the puncture assembly 35. When the clamping portion 331 is misaligned with the avoidance notch 313, the clamping portion 331 can clamp and fix the puncture assembly 35. When the clamping portion 331 is opposite to the avoidance notch 313, the clamping portion 331 shifts to the avoidance notch 313 to release the puncture assembly 35.
[0070] In other words, the clearance notch 313 is located at the bottom of the guide rib 312, and the clamping part 331 is elastic. When the clamping part 331 is misaligned with the clearance notch 313, the clamping part 331 deforms under the action of the guide rib 312 to clamp and fix the puncture component 35. When the clamping part 331 is opposite to the clearance notch 313, the clamping part 331 recovers its deformation under its own elastic force and shifts into the clearance notch 313 so that the clamping part 331 is separated from the puncture component 35 and the puncture component 35 is released.
[0071] Specifically, when disassembling the puncture assembly 35, the puncture assembly 35 is pulled along the first direction, causing the puncture assembly 35 to move the clamping member 33 along the first direction. At this time, the clamping part 331 slides relative to the guide rib 312. When the clamping part 331 moves to the position of the clearance notch 313, that is, when the clamping part 331 is opposite to the clearance notch 313, the clamping part 331 shifts into the clearance notch 313 under its own elastic force, thereby releasing the puncture assembly 35 to complete the disassembly of the puncture assembly 35; When installing the piercing assembly 35, first align the piercing assembly 35 with the clamping member 33, then push the piercing assembly 35 along the second direction, so that the piercing assembly 35 pushes the clamping member 33 to move along the second direction, so that the clamping part 331 gradually misaligns with the clearance notch 313 and cooperates with the guide rib 312, so that the clamping part 331 is offset towards the inside of the guide part 343 under the action of the guide rib 312 and clamps the piercing assembly 35, thereby completing the installation of the piercing assembly 35, and thus realizing the clamping, fixing and releasing of the piercing assembly 35 by the clamping member 33.
[0072] This application does not specifically limit the structure of the guide portion 343. Preferably, the guide portion 343 is a cylindrical structure disposed on the sleeve 341 and closed at the top end, so that the guide portion 343 can guide the clamping member 33 and increase the clamping stability of the clamping member 33 on the piercing assembly 35. In other embodiments, the guide portion 343 can also be other structures, as long as it can accommodate the clamping member 33.
[0073] Furthermore, the clamping member 33 also includes a limiting part 332 that can cooperate with the stop of the sleeve 341. The limiting part 332 has a guide surface 334 that can cooperate with the guide rib 312. The guide rib 312 is configured to press against the guide surface 334 to disengage the limiting part 332 from the sleeve 341 in a first direction.
[0074] Understandably, the limiting part 332 is also elastic and can stop with the sleeve 341 in the first direction. When the limiting part 332 stops with the sleeve 341 in the first direction, the sleeve 341 presses against the clamping member 33 in the first direction, causing the clamping member 33 and the sleeve 341 to move synchronously, so that the guide surface 334 and the guide rib 312 gradually approach each other. When the guide surface 334 abuts against the guide rib 312, the guide rib 312 applies an inward squeezing force to the guide surface 334, causing the limiting part 332 to disengage from the sleeve 341 in the first direction, thereby allowing the clamping member 33 to move relative to the sleeve 341 in the second direction.
[0075] Specifically, the clamping member 33 has a target position and a needle retraction position located above the target position. When the clamping member 33 moves to the target position, the guide surface 334 cooperates with the guide rib 312 to deform the limiting part 332 and release the stop cooperation with the sleeve 341, thereby enabling the clamping member 33 to move along the second direction and move to the needle retraction position to complete the needle retraction action.
[0076] Preferably, the side of the limiting part 332 away from the center of the guide part 343 is pointed, so as to ensure that the limiting part 332 can recover its deformation and cooperate with the sleeve 341 stop when it moves to the receiving groove 344.
[0077] The better one is to refer to Figure 2 , Figure 3 and Figure 6 The clamping member 33 also includes a connecting portion 333 located between the clamping portion 331 and the limiting portion 332. Both the clamping portion 331 and the limiting portion 332 are connected to the connecting portion 333. The connecting portion 333 has a stop wall that can cooperate with the puncture assembly 35 in the second direction to ensure that when the puncture assembly 35 is installed in the second direction, the clamping member 33 can move along the second direction with the puncture assembly 35.
[0078] This application does not specify the number or structure of the clamping parts 331. Preferably, refer to... Figure 5 Multiple clamping portions 331 are provided circumferentially along the connecting portion 333 to increase the number of clamping points for the puncture component 35, thereby increasing the clamping stability of the puncture component 35. Furthermore, the clamping portions 331 have an L-shaped vertical cross-section to further enhance the clamping stability of the puncture component 35. In other embodiments, only one clamping portion 331 may be provided, and the clamping portion 331 may also be any other structure that can achieve the clamping and fixing of the puncture component 35.
[0079] This application does not specifically limit the structure of the connecting part 333; preferably, refer to... Figure 6 The connecting part 333 is a closed-loop structure at one end to reduce the manufacturing difficulty of the clamping part 33. In other embodiments, the connecting part 333 can also be other structures, as long as it can connect the clamping part 331 and the limiting part 332 together and move along the second direction with the puncture assembly 35.
[0080] The better one is to refer to Figure 6 The limiting part 332 has an L-shaped vertical cross section. The number of limiting parts 332 is the same as the number of clamping parts 331 and they are arranged opposite to each other. The number of guide ribs 312 is the same as the number of clamping parts 331, so as to reduce the assembly difficulty of the continuous analyte concentration monitoring device and reduce the production cost of the continuous analyte concentration monitoring device.
[0081] The better one is to refer to Figure 2 and Figure 3 The guide portion 343 extends upward and protrudes from the top of the sleeve 341. The implantation unit 3 also includes a pull member 36 disposed in the guide portion 343. The two ends of the pull member 36 are respectively connected to the top wall of the guide portion 343 and the connecting portion 333, so that after the limiting portion 332 and the sleeve 341 are released from the stop engagement, the clamping member 33 can move to the needle withdrawal position under the action of the pull member 36 to complete the needle withdrawal action.
[0082] In this embodiment, preferably, refer to Figure 2 , Figure 3 and Figure 7 The puncture assembly 35 includes a needle hub 351, a puncture needle 352 mounted on the needle hub 351, and a sealing cylinder 353 connected to the needle hub 351. The sealing cylinder 353 and the needle hub 351 together form a sealed cavity, and the data acquisition unit 1 and the puncture needle 352 are at least partially located in the sealed cavity.
[0083] Since the puncture assembly 35 includes a needle hub 351, a puncture needle 352, and a sealing cylinder 353, the used puncture needle 352 can be stored in the sealing cylinder 353 to avoid the risk of harm to the user, thereby improving the user experience. Simultaneously, since the sealing cylinder 353 and the needle hub 351 together form a sealed cavity, and the data acquisition unit 1 and the puncture assembly 35 are located within the sealed cavity, the sterilized puncture needle 352 and the data acquisition unit 1 can be sealed and preserved, avoiding the risk of the puncture needle 352 and the data acquisition unit 1 carrying pathogens again, further improving the user experience and achieving the effect of conveniently sealing and preserving the data acquisition unit 1.
[0084] Preferably, the entire data acquisition unit 1 and the entire puncture needle 352 are located in the sealed cavity to ensure the sealing and preservation of the puncture needle 352 and the data acquisition unit 1.
[0085] This application does not specifically limit the structure of data acquisition unit 1; preferably, refer to... Figure 7 The data acquisition unit 1 includes an installation block and a sensor disposed on the installation block. The installation block is detachably connected to the needle holder 351, and the electronic unit 2 is provided with a groove-shaped structure for accommodating the installation block, so that the data acquisition unit 1 can be assembled on the electronic unit 2 at the same time as it is implanted into the subcutaneous tissue of the organism, thereby further simplifying the user's usage steps and improving the user experience.
[0086] Preferably, the mounting block is provided with a connecting hole, and the pin seat 351 is provided with a connecting post that can extend into the connecting hole, and the outer peripheral surface of the connecting post can abut against the hole wall of the connecting hole, so as to achieve a detachable connection between the two by utilizing the abutting force between the connecting post and the hole wall.
[0087] In other implementation examples, the data acquisition unit 1 may also include only a sensor, that is, the sensor is simply placed in a sealed cavity and has no connection with the needle holder 351. In this case, when using the continuous analyte concentration monitoring device, the data acquisition unit 1 needs to be assembled into the electronic unit 2 first.
[0088] Furthermore, refer to Figure 7 The needle holder 351 includes a blocking section 354, a connecting section 355 with a diameter smaller than that of the blocking section 354, and a sealing rib 356 disposed on the connecting section 355. The sealing rib 356 and the blocking section 354 form an accommodating space. The blocking section 354 is installed on the clamping member 33 and at least a portion of the clamping member 33 is located in the accommodating space. The sealing cylinder 353 abuts against the sealing rib 356.
[0089] It is understood that the blocking section 354 is installed in the space formed by the multiple clamping parts 331, and the ends of the multiple clamping parts 331 extend into the accommodating space to achieve clamping of the needle seat 351.
[0090] Since the blocking section 354 is installed on the clamping member 33 and at least a portion of the clamping member 33 is located in the accommodating space, the clamping stability of the clamping member 33 on the needle seat 351 is increased, thereby ensuring the smoothness of the implantation and withdrawal actions. Furthermore, since the sealing cylinder 353 abuts against the sealing rib 356, the connection area between the sealing cylinder 353 and the needle seat 351 is increased, thereby increasing the sealing performance between the sealing cylinder 353 and the needle seat 351, ensuring the sealing performance of the sealing cavity, and further ensuring the sealing and preservation effect of the data acquisition unit 1.
[0091] Furthermore, refer to Figure 2 , Figure 3 and Figure 5 The sleeve 341 has an elastic arm 345 on its periphery. The elastic arm 345 has a locking block 346 protruding outward from the housing 31. The housing 31 is provided with a stop opening 314. When the clamping member 33 is in the initial position and the limiting part 332 is engaged with the stop of the sleeve 341, the locking block 346 is engaged with the stop wall of the stop opening 314. At this time, the pulling member 36 applies a pulling force along the second direction to the clamping member 33, and the elastic member 342 is in a compressed state to limit the clamping member 33 to the initial position. When implanting the data acquisition unit 1, the locking block 346 is pressed towards the inside of the housing 31 to deform the elastic arm 345, so that the locking block 346 contacts and engages with the stop wall of the stop opening 314, so that the sleeve 341 moves along the first direction under the action of the elastic member 342, thereby moving the clamping member 33 to the target position to complete the implantation action.
[0092] Furthermore, refer to Figure 2 and Figure 3 An unlocking block 315 is provided at the stop 314. The unlocking block 315 can slide radially along the housing 31 so that when the locking block 346 engages with the stop of the stop wall of the stop 314, only the unlocking block 315 needs to be pressed to facilitate the triggering of the elastic element 342.
[0093] In Example 2, the pushing component 34 includes a sleeve 341 and an elastic member 342 acting on the sleeve 341. The clamping member 33 includes a connecting part 333 and a clamping part 331. The housing 31 is provided with a guide part 343. The bottom of the guide part 343 is provided with a relief groove. When the clamping part 331 is misaligned with the relief groove, the clamping part 331 can clamp and fix the puncture component 35. When the clamping part 331 is opposite to the relief groove, the clamping part 331 releases the puncture component 35.
[0094] Understandably, the clamping part 331 is elastic, so that when the piercing component 35 is installed along the second direction, the piercing component 35 pushes the clamping part 33 to move along the second direction, so that the clamping part 331 gradually misaligns with the clearance groove and cooperates with the inner wall of the guide part 343, thereby causing the clamping part 331 to deform under the action of the guide part 343 to clamp and fix the piercing component 35; and when the clamping part 331 moves to the position where the clearance groove is located, the clamping part 331 deforms towards the outside of the guide part 343 through the clearance groove under the action of its own elasticity to release the piercing component 35.
[0095] Furthermore, the pushing component 34 also includes a limiting block capable of reciprocating along a third direction perpendicular to the first direction, a driving member for applying force to the limiting block, and a switching block disposed inside the housing 31. The driving member applies a force toward the puncture component 35 to the limiting block so that the limiting block can stop and engage with the puncture component 35 in the second direction. The switching block applies a force away from the puncture component 35 to the limiting block so that the limiting block overcomes the force of the driving member and separates from the puncture component 35.
[0096] Understandably, when the clamping member 33 is in the released position, the switching block applies a force away from the puncture component 35 to the limiting block, so as to separate the limiting block from the puncture component 35, thereby facilitating the removal of the puncture component 35; while when the puncture component 35 is installed along the second direction, the puncture component 35 cooperates with the limiting block, thereby causing the sleeve 341 to move along the second direction with the puncture component 35, so as to compress the elastic member 342 with the sleeve 341, thereby storing force on the elastic member 342 while installing the puncture component 35.
[0097] Furthermore, the puncture assembly 35 includes a needle seat 351, a puncture needle 352 mounted on the needle seat 351, and a sealing cylinder 353 connected to the needle seat 351. The sealing cylinder 353 is provided with an abutment portion that can cooperate with the stop of the limiting block, so that during the process of installing the puncture assembly 35 on the clamping member 33 in the second direction, the abutment portion cooperates with the stop of the limiting block in the second direction, thereby realizing the compression of the elastic member 342 while installing the puncture assembly 35 in the second direction.
[0098] This application does not impose specific limitations on the structure of the driving component. Preferably, the driving component is a spring to ensure the elastic driving effect of the driving component on the limiting block. In other embodiments, the driving component can also be an elastic sheet or an elastic column, or other structures capable of applying elastic force to the limiting block.
[0099] In a preferred embodiment, the continuous analyte concentration monitoring device further includes a push rod slidably connected to the housing 31. The push rod can act on the clamping member 33 to push the clamping member 33 to the release position, thereby facilitating the disassembly of the puncture assembly 35.
[0100] Understandably, the push rod and clamp 33 are located inside the guide portion 343 to increase the stability of the push rod and clamp 33 during movement.
[0101] It should be noted that in this embodiment, the charging component 32 needs to be arranged to avoid the push rod. That is, the charging component 32 can be arranged on the periphery or top of the mounting position, or the charging component 32 can be arranged on the side of the top of the housing 31, or the charging component 32 can be arranged on the side of the housing 31.
[0102] Furthermore, the push rod is provided with a mating part, and the inner wall of the guide part 343 is provided with a stop part and a clearance part. When the mating part and the stop part are mated, the push rod and the clamping member 33 form a clearance. When the mating part and the clearance part are mated, the push rod can push the connecting member to the release position.
[0103] In other words, when the data acquisition unit is implanted into the subcutaneous tissue of a living organism, the mating part and the stop part cooperate to allow the push rod and the clamp 33 to avoid each other, so as to ensure that the clamp 33 can move to the needle withdrawal position, thereby facilitating the disassembly of the puncture assembly 35; when disassembling the puncture assembly 35, the mating part and the avoidance part cooperate to allow the push rod to slide relative to the guide part 343, thereby allowing the push rod to push the clamp 33 to the release position, thereby facilitating the disassembly of the puncture assembly 35.
[0104] Preferably, the mating part is a strip structure provided on the outer peripheral surface of the push rod and extending along the axial direction of the push rod. The inner wall of the guide part 343 is provided with multiple arc-shaped structures along its circumference, so that the arc-shaped structures form a stop part and the space between the arc-shaped structures forms a clearance part. Thus, when switching the mating part from the state of being mated with the stop part to the state of being mated with the clearance part, it is only necessary to rotate the push rod, so as to facilitate the switching of the mating state of the mating part.
