Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary equipment, and in particular to a transmitter locking and fixing mechanism and an implantation tool. Background Art

[0002] The dynamic blood glucose monitoring system CGM is a system used to monitor the blood sugar index of the human body. The dynamic blood glucose monitoring system CGM in the prior art is to send the sensor into the subcutaneous tissue of the human body. The enzyme on the sensor reacts with the subcutaneous tissue fluid to detect the blood sugar value, and cooperates with the transmitter to send the blood sugar value to the terminal, so as to realize real-time dynamic monitoring of blood sugar conditions. The dynamic blood glucose monitoring system CGM only needs to be implanted once, and then it can continuously monitor the blood sugar data in the body through Bluetooth connection, eliminating the pain of frequent injections of traditional blood glucose meters, and making up for the cumbersome operation of traditional blood glucose meters that can only monitor once. The transmitter and sensor are usually assembled in an implantation tool, and the sensor and transmitter can be simply and quickly implanted into the human body through the implantation tool.

[0003] Since the transmitter needs to be left in the human body eventually, in order to facilitate the use of the implant tool, the transmitter is separated from the implant tool. Therefore, in the prior art, the transmitter is only slightly connected to the implant tool, and the connection between the transmitter and the internal structure of the implant tool is not particularly tight. In this way, although it is beneficial to separate the transmitter during subsequent use, it also causes the transmitter to be easily separated from the internal structure of the implant tool during transportation, etc., affecting the normal use of the implant tool. In particular, when the implant tool falls or encounters unexpected situations, the transmitter is very easy to fall off from the connection position in the implant tool.

[0004] Therefore, how to provide a transmitter locking and fixing mechanism to lock and fix the transmitter more stably is a technical problem that needs to be solved urgently in this field. Summary of the invention

[0005] In view of the above technical problems, the present invention provides a transmitter locking and fixing mechanism, which is provided with a locking piece. The locking piece can move relative to the transmitter, so as to abut and limit the transmitter, or be separated from the transmitter, so as to achieve stable fixation of the transmitter. At the same time, since it can be separated from the transmitter, it is also convenient for the subsequent separation of the transmitter, and will not affect the normal use of the implant tool.

[0010] Preferably, the limiting member is used to abut against and limit the locking member, so as to compress the elastic member and cause the locking member to remain in the locked state; After the locking member slides away from the limiting member, the elastic member stretches to cause the locking member to remain in the unlocked state.

[0024] The present invention provides a transmitter locking and fixing mechanism, which includes a transmitter and a locking member; the locking member is movably connected to the transmitter; wherein the locking member has a locking state and an unlocking state after being moved relative to the transmitter; in the locking state, the locking member is connected to the transmitter to lock and limit the transmitter; in the unlocking state, the locking member is separated from the transmitter. By providing the locking member that can move relative to the transmitter, the relative position of the locking member relative to the transmitter can be adjusted, and the transmitter can be fixed, locked or unlocked, so as to better adapt to the use of the implantation tool. When the implantation tool is not in use, the position of the transmitter can be limited by the locking member to ensure that the transmitter will not fall off accidentally; and after the implantation tool is used, the locking member can be separated from the transmitter without affecting the normal separation of the transmitter.

[0025] Please refer to Figures 1 to 8 In one embodiment, a transmitter locking and fixing mechanism 100 is provided, which is mainly used to lock and fix the transmitter in the implant tool more stably to prevent the transmitter from accidentally falling off in the implant tool, while also taking into account the normal use of the implant tool.

[0026] The transmitter locking and fixing mechanism 100 includes a transmitter 10 and a locking member 20. The locking member 20 is movably connected to the transmitter 10, that is, the locking member 20 and the transmitter 10 can move relative to each other. The specific movement mode can be rotation, movement, deformation, etc. It only needs to change the relative position relationship between the locking member 20 and the transmitter 10 to achieve the locking and unlocking of the transmitter 10. The locking member 20 has a locking state and an unlocking state after moving relative to the transmitter 10. In the locking state, the locking member 20 is connected to the transmitter 10 to lock and limit the transmitter 10. In the unlocking state, the locking member 20 is separated from the transmitter 10. In other words, the locking member 20 has at least two states, and in these two states, the positional relationship between the locking member 20 and the transmitter 10 is different. In the locked state, the locking member 20 is connected to the transmitter 10, thereby limiting the position of the transmitter 10; in the unlocked state, the locking member 20 is separated from the transmitter 10, and the position of the transmitter 10 is no longer limited by the locking member 20. In the implantation tool, the locking member 20 can be installed on any component (such as a housing, a push member, etc.), thereby stably fixing the transmitter 10 in the implantation tool; since the locking member 20 can also be separated from the transmitter 10, it will not affect the subsequent use of the implantation tool, and the transmitter 10 is separated from the implantation tool.

[0027] It is understandable that in the prior art, the transmitter is usually slightly stuck in the implant tool (for example, in some prior art, the transmitter is slightly stuck on the ejection piece) because it is considered that the transmitter needs to be separated from the implant tool after use, so that it can be left on the human body more easily. This also leads to the transmitter being easily separated from the ejection piece. In particular, when the implant tool falls or other unexpected situations occur, the transmitter is easy to fall off from the ejection piece, thereby affecting the normal use of the subsequent implant tool.

[0028] The locking member 20 is provided in the transmitter locking and fixing mechanism 100 provided in this embodiment. Since the locking member 20 can be unlocked relative to the transmitter 10, the locking member 20 can be connected more tightly in the locked state, and a greater locking force can be applied to the transmitter 10 through the locking member 20, so that the transmitter 10 can be more stably fixed in the implant tool, thereby better preventing the transmitter from accidentally falling off from the implant tool. At the same time, since the locking member 20 can be movable relative to the transmitter 10, after the implant tool is used, the transmitter 20 can be unlocked by the movement of the locking member 20 relative to the transmitter 10, so that the transmitter 20 can be smoothly separated from the implant tool, thereby ensuring the normal use of the implant tool.

[0029] Preferably, in one embodiment, the transmitter locking and fixing mechanism 100 further includes an excitation member, which is connected to the locking member 20 and is used to switch the state of the locking member 20. That is, in this embodiment, the locking member 20 can be controlled to move relative to the transmitter 10 by the excitation member to complete the control switching of the locking member 20 between the locked state and the unlocked state.

[0030] Preferably, in one embodiment, the excitation member is an elastic member 30, wherein the elastic member 30 refers to a member that can undergo elastic deformation after being subjected to force, and can restore to its original position state when the force is reduced or disappears. The elastic member 30 is connected to the locking member 20 to cause the locking member 20 to remain in a state. That is, in this embodiment, the locking member 20 can be maintained in the locked state or the unlocked state by the elastic force of the elastic member 30, so as to ensure that the locking member 20 can lock the transmitter 10 more stably in the locked state, or can ensure that the locking member 20 can be separated from the transmitter 10 more stably and smoothly in the unlocked state. And through the setting of the elastic member 30, it is possible to control the position state of the locking member 20 without setting a complex control structure in the implantation tool.

[0031] Specifically, in one embodiment, the elastic member 30 is a spring.

[0032] Preferably, in one embodiment, the transmitter locking and fixing mechanism 100 further includes a limiting member 40, and the limiting member 40 is used to abut against and limit the locking member 20, so that the elastic member 30 is deformed, and the locking member 20 is maintained in another state. Wherein, deforming the elastic member 30 means: causing the elastic member 30 to undergo a deformation different from its initial state (such as stretching or compression, etc.), so that when the force on the elastic member 30 is reduced or disappears, the elastic member 30 can automatically restore the initial state. That is to say, in this embodiment, the limiting member 40 can limit the position of the locking member 20, so that the locking member 20 applies force to the elastic member 30, causing the elastic member 30 to deform, thereby causing the locking member 20 to maintain in another state. For example, when the elastic member 30 is used to maintain the locking member 20 in the locked state, the limiting member 40 is used to maintain the locking member 20 in the unlocked state; and when the elastic member 30 is used to maintain the locking member 20 in the unlocked state, the limiting member 40 is used to maintain the locking member 20 in the locked state. The locking member 20 and the limiting member 40 can be slidably separated, that is, the locking member 20 and the limiting member 40 can slide relative to each other, so that the locking member 20 and the limiting member 40 are separated, so that the limiting member 40 will no longer squeeze and limit the locking member 20, thereby releasing the elastic member 30. That is to say, in this embodiment, the limiting member 40 can apply a resistance to the locking member 20 to limit the elastic member 30, thereby causing the locking member 20 to maintain in one state, and by controlling the relative sliding between the limiting member 40 and the locking member 20, the limiting member 40 and the locking member 20 can be separated, so that the locking member 20 is no longer restricted, thereby releasing the elastic member 30, and allowing the elastic member 30 to drive the locking member 20 to maintain in another state. Through this structure, the position state of the locking member 20 can be controlled by controlling the relative sliding between the limiting member 40 and the locking member 20, and the overall structure is simpler and does not require a complex control structure. Among them, the locking member 20 and the limiting member 40 can be set on the parts that can slide relative to each other in the implant tool, so that no additional driving structure is required in the implant tool, and the control of the position state of the locking member 20 can more accurately adapt to the use state of the implant tool. Meanwhile, the relative sliding stroke between the limiting member 40 and the locking member 20 can be controlled to more accurately control the timing of the position change of the locking member 20 during the use of the implantation tool.

[0033] Preferably, in one embodiment, the limiting member 40 is used to abut against and limit the locking member 20, so that the elastic member 30 is compressed, and the locking member 20 is maintained in the locked state; after the locking member 20 and the limiting member 40 are slid and separated, the elastic member 30 is stretched, and the locking member 20 is maintained in the unlocked state. That is to say, in this embodiment, the limiting member 40 is specifically used to limit the locking member 20 in the locked state, in which state, the elastic member 30 is squeezed and compressed by the locking member 20, so that the transmitter 10 is stably locked and fixed by the locking member 20; and when the limiting member 40 and the locking member 20 are separated, the locking member 20 is no longer restricted, and the elastic member 30 loses the external limiting resistance, so that it can automatically stretch through its own elasticity, thereby driving the locking member 20 to move relative to the transmitter 10, so that the locking member 20 is separated from the transmitter 10.

[0034] Specifically, in one embodiment, the locking member 20 and the transmitter 10 are movably connected in such a manner that the locking member 20 and the transmitter 10 can move relative to each other. The direction in which the locking member 20 and the transmitter 10 can move relative to each other is perpendicular to the direction in which the transmitter 10 can move in the implant tool, for example Figure 3 As shown in the direction angle, the transmitter 10 can move vertically in the implant tool, while the locking member 20 can move horizontally, so that the locking member 20 can lock and fix the transmitter 10 more stably.

[0035] Preferably, in one embodiment, the stopper 40 is disposed on the housing 200 of the implantation tool. In this embodiment, since the stopper 40 is disposed on the housing 200, after the locking member 20 moves relative to the stopper 40, the position of the locking member 20 in the housing 200 changes, so that the state of the locking member 20 at different positions in the housing 200 can be controlled, so that the unlocking of the locking member 20 can be more accurately adapted to the use process of the implantation tool.

[0036] It can be understood that when the limit member 40 is set on the shell 200, by controlling the unlocking stroke between the locking member 20 and the limit member 40, it can be ensured that during the implantation process, before the transmitter 10 moves out of the shell 200, the locking member 20 is already in the unlocked state, so that the transmitter 10 is unlocked before moving out of the shell 200. When the transmitter 10 is attached to the user's skin, there will be no dragging feeling, which improves the user's experience.

[0037] Specifically, in one embodiment, a limit arm 23 is provided on the locking member 20, and in the locked state, the limit arm 23 is blocked by the limit member 40 to compress the elastic member 30. In the unlocked state, the limit arm 23 is located below the limit member 40, so that the space for the limit arm 23 to move upward is blocked by the limit member 40, so that the locking member 20 cannot be directly restored to the locked state, thereby avoiding secondary use by users and ensuring safety.

[0038] Preferably, in one embodiment, the locking members 20 are provided in plurality (at least two), and along the extension direction of the side of the transmitter 10 (for example, when the transmitter 10 is circular, the extension direction along the side of the transmitter 10 is along the circumference of the transmitter 10), all the locking members 20 are arranged in sequence and spaced apart, so that in the locked state, the transmitter 10 can be connected to the transmitter 10 from different positions and directions through the plurality of locking members 20, so that the force between the locking members 20 and the transmitter 10 is more balanced, and the transmitter 10 can be better prevented from being deflected. Specifically, in one embodiment, two locking members 20 are provided, and the two locking members 20 are arranged on opposite sides of the transmitter 10, so that in the locked state, the two locking members 20 can connect and limit the transmitter 10 from opposite sides of the transmitter 10.

[0039] Preferably, in one embodiment, the elastic member 30 is disposed between the two locking members 20, and the locking member 20 is provided with a support column 21 extending into the elastic member 30. With this structure, the elastic member 30 can be better supported, and the force direction between the locking member 20 and the elastic member 30 can be better guided, ensuring that the locking member 20 can smoothly compress the elastic member 30 to a desired state; and during the recovery process of the elastic member 30, the elastic member 30 can be guided to the force direction of the locking member 20, ensuring that the locking member 20 moves to a desired position.

[0040] Specifically, in one embodiment, the locking member 20 adopts a caliper structure, and in the locking state, the locking member 20 is clamped into the transmitter 10.

[0041] Preferably, in one embodiment, a recessed groove 111 is provided on the outer surface of the shell 11 of the transmitter 10, and in the locked state, the locking member 20 is at least partially inserted into the recessed groove 111. That is, in this embodiment, in the locked state, at least a portion of the locking member 20 is inserted into the recessed groove 111, so as to lock and limit the transmitter 10. Of course, in other embodiments, in the locked state, the locking member 20 may also abut against the outer surface of the shell 11 (for example, the locking member 20 abuts against the circumferential surface of the shell 11, and the locking member 20 applies pressure to the circumferential surface of the shell 11, thereby locking and limiting the transmitter 10; or the locking member 20 may abut against the bottom surface of the shell 11, and the transmitter 10 is lifted by the locking member 20, thereby locking and limiting the transmitter 10). In this embodiment, by inserting the locking member 20 into the recessed groove 111, the limiting effect on the transmitter 10 can be better ensured, so that the locking member 20 and the transmitter 10 are not easily slipped off and separated. Specifically, in one embodiment, the recessed groove 111 is opened on the side of the housing 11, so that when the locking member 20 is inserted into the recessed groove 111, the locking member 20 cooperates with the bottom wall and the top wall of the recessed groove 111 to lock and limit the transmitter 10 more stably.

[0042] Specifically, in one embodiment, a hook 22 is provided on the locking member 20 , and in the locking state, the hook 22 is correspondingly inserted into the recessed groove 111 .

[0043] It is understandable that, in order to improve the locking effect of the transmitter 10, in the locked state, the locking member 20 can partially cover the transmitter 10. That is, the overall shape of the locking member 20 can be adapted to the outer surface of the housing 11, so that in the locked state, it can cover the outer surface of the housing 11.

[0044] Preferably, in one embodiment, the locking member 20 is movably arranged on the ejection member 300 in the implantation tool, so as to connect the transmitter 10 with the ejection member 300 in the locking state. That is, in this embodiment, the locking member 20 is used to realize the connection between the ejection member 300 and the transmitter 10, and the state of the locking member 20 is changed by the movement of the locking member 20 relative to the ejection member 300, so as to realize the locking, fixing or separation between the ejection member 300 and the transmitter 10. By movably arranging the locking member 20 on the ejection member 300, it is not necessary to set an additional connection structure between the ejection member 300 and the transmitter 10, and the transmitter 10 can be fixed on the ejection member 300 more stably through the locking member 20.

[0045] In one embodiment, the transmitter locking and fixing mechanism 100 uses the locking member 20 to lock and fix the transmitter 10. The transmitter 10 and the component can be locked and fixed to each other by simply setting the locking member 20 on another component. The transmitter 10 is laterally wrapped by the locking member 20, thereby ensuring that the transmitter 10 is locked. The elastic member 30 can also stimulate the locking member 20, so that the locking member 20 loosens the transmitter 10.

[0046] At the same time, in one embodiment, an implantation tool 1000 is also provided, which includes the transmitter locking and fixing mechanism 100, as well as the housing 200, the ejection member 300, the driving member 400, the driving spring 500, the sensor 600, and the implantation needle assembly 700. The transmitter 10 and the locking member 20 are arranged in the housing 200. The ejection member 300 is buckled and arranged in the housing 200, wherein "buckle" refers to a connection between one component and another component through a corresponding buckle structure, and the two components can be separated from each other in a corresponding state. The driving member 400 is arranged in the housing 200 to drive the ejection member 300 to be disengaged, that is, the change of the state of the ejection member 300 is driven by the driving member 400, and the ejection member 300 can be changed from the "buckle" state to the "disengagement" state by the driving member 400, so that the ejection member 300 is separated from the housing 200. The driving spring 500 is arranged between the housing 200 and the ejection member 300 to drive the ejection member 300 to move. The sensor 600 is arranged in the housing 200, and the implantation needle assembly 700 is buckled and arranged on the ejection member 300. When in use, the user operates the driving member 400 to disengage the ejection member 300, so that the driving spring 500 will drive the ejection member 300 to move, and the ejection member 300 will synchronously drive the implantation needle assembly 700 to move, thereby piercing the skin. Among them, the transmitter 10 can be arranged on the ejection member 300, so that when the ejection member 300 moves, the transmitter 10 is synchronously driven to move; or the transmitter 10 can also be arranged at other positions in the housing 200 (for example, arranged at the bottom of the housing 200). The sensor 600 can be arranged on the ejection member 300, or directly arranged in the transmitter 10. It is only necessary that the sensor 600 can be connected to the transmitter 10 in the end, and the transmitter 10 and the sensor 600 can be left on the human body.

[0047] Preferably, in one embodiment, the locking member 20 is movably arranged on the ejection member 300, so as to lock and connect the transmitter 10 to the ejection member 300. When the user is in use, after the ejection member 300 is released, it will synchronously drive the transmitter 10 to move, and after moving to a certain position, the locking member 20 moves relative to the transmitter 10, so that the transmitter 10 is separated from the ejection member 300. Preferably, in one embodiment, the limiting member 40 is arranged on the housing 200, and when the ejection member 300 moves, the locking member 20 and the limiting member 40 move relative to each other, and when the locking member 20 moves to a certain distance, it is separated from the limiting member 40, and then the locking member 20 is separated from the transmitter 10 driven by the elastic member 30.

[0048] Preferably, in one embodiment, the limiting member 40 is also used to squeeze and limit the ejection member 300, so as to buckle the implant needle assembly 700 on the ejection member 300. That is to say, in this embodiment, the limiting member 40 is not only used to squeeze and limit the locking member 20, but also used to squeeze and limit the ejection member 300. By squeezing and limiting the ejection member 300, the deformation of the ejection member 300 is limited, so that the ejection member 300 buckles and locks the implant needle assembly 700. When the ejection member 300 moves a certain distance, the ejection member 300 can be separated from the limiting member 40.

[0049] Specifically, in one embodiment, the ejection member 300 includes an ejection member body 310 and a needle cap clamp arm 320 connected to the ejection member body 310, and the needle cap clamp arm 320 and the ejection member body 310 together enclose a lock cap cavity 330. When the implantation tool 1000 is not in use, the stopper 40 abuts against the needle cap clamp arm 320, so that the needle cap clamp arm 320 buckles the implantation needle assembly 700 in the lock cap cavity 330.

[0050] Preferably, in one embodiment, the implant needle assembly 700 includes a needle cap 710, a needle 720, an implant needle 730, and a needle retracting elastic member 740, wherein the needle retracting elastic member 740 refers to a member that can undergo elastic deformation after being subjected to force, and can restore to its original position when the force is reduced or disappears. The needle cap 710 is located in the needle locking cavity 330, the needle 720 is connected to the needle cap 710, the implant needle 730 is connected to the needle 720, and the needle retracting elastic member 740 is disposed between the needle cap 710 and the ejection member 300. When the implant tool 1000 is not in use, the limiting member 40 abuts against the needle cap clamp arm 320, so that the needle cap clamp arm 320 locks the needle cap 710 in the lock cap cavity 330 and compresses the needle retracting elastic member 740. After the implantation tool 1000 is used, the ejection member 300 moves to a certain distance, the needle cap clamping arm 320 separates from the limiting member 40, and the needle withdrawal elastic member 740 stretches to drive the needle cap 710 to move out of the locking cap cavity 330. In other words, when the implantation tool 1000 is not used, the limiting member 40 abuts against the needle cap clamping arm 320, thereby limiting the position of the needle cap clamping arm 320, so that the needle cap clamping arm 320 presses the needle cap 710, and the needle withdrawal elastic member 740 connected to the needle cap 710 is compressed. After the implantation tool 1000 is used, the position limiter 40 is separated from the needle cap clamping arm 320, and the position and shape of the needle cap clamping arm 320 are no longer limited, so that the pressure applied by the needle cap clamping arm 320 to the needle cap 710 is less than the elastic force of the needle withdrawal elastic member 740. The needle withdrawal elastic member 740 drives the needle cap 710 to move through its own restoring force, causing the needle cap clamping arm 320 to move and deform, so that the needle cap 710 rushes out of the locking cap cavity 330. The implantation needle 730 is connected to the needle cap 710 through the needle 720. Therefore, when the implantation tool is not in use or in use, the position of the needle cap 710 can be limited by the needle cap clamping arm 320, thereby ensuring the stability of the position of the implantation needle 730 and ensuring that the implantation needle 730 can penetrate the skin under the drive of the ejection member 300. When the implant needle 730 penetrates the skin, the needle cap clamping arm 320 is separated from the limiting member 40, so that the needle cap 710 can move to drive the implant needle 730 to retreat, thereby completing the automatic needle withdrawal function of the implant tool 1000.

[0051] Specifically, in one embodiment, two needle cap clamping arms 320 may be provided, and the two needle cap clamping arms 320 apply force to the needle cap 710 from opposite sides, so as to ensure the reliability of the needle cap clamping arms 320 locking the needle cap 710. Correspondingly, a stopper 40 may be provided on the outer side of each needle cap clamp 320 to abut and limit the needle cap clamping arms 320.

[0052] Preferably, in one embodiment, the unlocking stroke of the needle cap clamp arm 320 is greater than the unlocking stroke of the locking member 20. That is to say, in this embodiment, when the locking member 20 and the needle cap clamp arm 320 are simultaneously provided in the ejection member 300, after the ejection member 300 is disengaged and the ejection member 300 and the limiting member 40 move relative to each other, the locking member 20 is first separated and unlocked from the limiting member 40, and then the needle cap clamp arm 320 is separated and unlocked, and the timing of the two unlocking positions is not the same. In this way, the locking member 20 can first unlock the transmitter 10, and then the needle withdrawal operation can be performed, so as to ensure the downward distance of the implant needle 730 and ensure that the implant needle 730 is withdrawn after piercing the skin. At the same time, the unlocking operation can also be completed before the transmitter 10 is attached to the human body, thereby avoiding a dragging feeling to the user.

[0053] Preferably, in one embodiment, the ejection member 300 and / or the locking member 20 are provided with an insertion hole 50, and in the locked state, the limiting member 40 is inserted into the insertion hole 50. The setting of the insertion hole 50 can facilitate the assembly of the limiting member 40. During assembly, the limiting member 40 can be first installed on the ejection member 300, and then the ejection member 300 can be installed as a whole into the housing 200, thereby reducing the difficulty of assembly.

[0054] Preferably, in one embodiment, the limiting member 40 includes a first blocking portion 41 and a second blocking portion 42. The first blocking portion 41 is used to abut against the locking member 20, and the second blocking portion 42 is used to abut against the needle cap clamping arm 320. That is, in this embodiment, the limiting member 40 abuts against the structures that need to be limited on the ejection member 300 through different position areas, so as to better avoid interference between components.

[0055] It is understandable that in the prior art, the transmitter needs to have a pinhole in order to avoid the implantation needle. However, due to the opening of the pinhole, contaminants can easily enter the transmitter through the pinhole, causing contamination to the structure inside the transmitter. In particular, when contaminants enter the transmitter and contaminate the sensor and the implantation needle, when the user uses the implantation tool, it is easy to cause infection to the user, affecting safety.

[0056] Preferably, in one embodiment, a seal 800 is provided between the implant needle assembly 700 and the transmitter 10, the seal 800 abuts against the housing 11, and the seal 800 is located at the pinhole 112 of the housing 11. That is, the seal 80 abuts against the surface of the housing 11 and is located at the pinhole 112, thereby shielding the pinhole 112 to prevent contaminants from entering the transmitter 10 from the pinhole 112. Since the transmitter 10 is locked on the ejection member 300 by the locking member 20, and the implant needle assembly 700 is buckled on the ejection member 300, the relative position of the transmitter 10 and the implant needle assembly 700 is limited, so that the seal 800 can be pressed against the housing 11, thereby further ensuring the sealing effect of the seal 800.

[0057] Specifically, in one embodiment, the seal 800 is a soft rubber seal, that is, the seal 800 can be deformed to a certain extent after being subjected to force, so as to better ensure the sealing effect. More specifically, the seal 800 can be a silicone seal.

[0058] Specifically, in one embodiment, the sealing member 800 is provided with an avoidance hole 810 opposite to the needle hole 112, so that the implantation needle 730 can be avoided through the avoidance hole 810. The sealing member 800 can be an annular sealing member.

[0059] Specifically, in one embodiment, the sealing member 800 is disposed at the bottom of the needle 720 .

[0060] Preferably, in one embodiment, in the locking state, the locking member 20 at least partially extends into the implant needle assembly 700 to limit the position of the implant needle assembly 700. That is to say, in this embodiment, in the locking state, a portion of the locking member 20 extends into the implant needle assembly 700, thereby limiting the position of the implant needle assembly 700. Since the locking member 20 is arranged on the ejection member 300, the stability of the implant needle assembly 700 being snapped onto the ejection member 300 can be better ensured. In addition, since in the locking state, the locking member 20 is also connected to the transmitter 10 for limiting position, the position of the transmitter 10 and the implant needle assembly 700 is limited, thereby ensuring the compression of the sealing member 800 and further ensuring the sealing effect. And because the locking member 20 limits the implant needle assembly 700, the implant needle assembly 700 can only be withdrawn after the locking member 20 separates and unlocks the implant needle assembly 700. This further ensures that when the implant tool 1000 is in use, the transmitter 10 is unlocked before the needle is withdrawn.

[0061] Specifically, in one embodiment, a slot 7201 is provided on the needle 720 , and a locking arm 24 is provided on the locking member 20 . When in the locking state, the locking arm 24 is inserted into the slot 7201 .

[0062] Preferably, in one embodiment, the implantation tool 1000 further includes a sealing sleeve 900, which is detachably connected to the bottom of the transmitter 10 and seals the pinhole 112 at the bottom of the housing 11. The sealing member 800 is located at the top of the housing 11. That is, in this embodiment, the sealing member 800 only seals the pinhole 112 at the top of the transmitter 10, while the pinhole 112 at the bottom of the transmitter 10 is sealed by the sealing sleeve 900. By setting the sealing sleeve 900, when using the implantation tool 1000, the sealing sleeve 900 can be disassembled first, so as not to affect the subsequent attachment of the transmitter 10 to the human body. In addition, the sealing sleeve 900 can be connected to the bottom shell in the implantation tool 1000, so that the sealing sleeve 900 can also support and limit the transmitter 10, which can better prevent the implantation tool 1000 from accidentally falling and affecting its use. The locking member 20 cooperates with the sealing member 800 to seal the top of the transmitter 10, and the sealing sleeve 900 seals the bottom of the transmitter 10, thereby improving the sealing effect. Due to the improved sealing effect, it is no longer necessary to set additional sealing components such as silicone in the transmitter 10, which can simplify the internal structure of the transmitter 10 and reduce the difficulty of assembling the transmitter 10.

[0063] More preferably, in one embodiment, an elastic seal 910 abutting against the bottom of the shell 11 is disposed inside the sealing sleeve 900, and the sealing sleeve 900 presses the elastic seal 910 against the bottom of the shell 11, thereby further improving the sealing effect.

[0064] In the implantation tool 1000, there is only one tiny pinhole 112 on the transmitter 10, which increases the aesthetics of the transmitter 10. The locking member 20 and the sealing member 800 can protect the implantation needle 730 and the sensor 600 before implantation, so that the implantation needle 730 and the sensor 600 are not contaminated or damaged by foreign objects, and the implantation needle 730 and the sensor 600 are isolated from the external space before implantation. As long as the locking member 20 is not loose, the sealing function can always protect the implantation needle 730 and the sensor 600. In addition, during the production and assembly process, it can also be achieved that the implantation needle 730 and the sensor 600 will not loosen during the gamma sterilization and transportation process.

[0065] The above description is only an implementation mode of the present invention. It should be pointed out that, for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present invention, but these all belong to the protection scope of the present invention.
