[0002] A continuous glucose monitoring (CGM) system is a system used to monitor blood sugar levels. Conventional CGM systems insert a sensor into the subcutaneous tissue of the human body. The enzyme on the sensor reacts with the subcutaneous tissue fluid to detect blood sugar levels, and a transmitter transmits the blood sugar levels to a terminal, enabling real-time dynamic monitoring of blood sugar levels. A CGM system only needs to be implanted once and then continuously monitors blood sugar levels via Bluetooth connection, eliminating the pain of frequent needle insertions and complicating the tedious process of traditional blood sugar meters, which can only measure blood sugar once per test.

[0003] Currently, transmitters are typically incorporated into implantation tools, which have pinholes designed to allow the needle inside the tool to pass through. These pinholes can easily allow contaminants to enter the transmitter through these holes, potentially contaminating internal components such as the sensor and the implantation needle.

[0046] The present invention provides a transmitter sealing mechanism, comprising a sealing member and a locking member; the sealing member abuts against the transmitter housing and is located at a pinhole on the transmitter housing; the locking member is connected to the transmitter housing to limit the position of the transmitter housing and press the sealing member against the transmitter housing. The transmitter sealing mechanism is provided with the sealing member so that the pinhole on the transmitter housing can be sealed by the sealing member, and is also provided with the locking member. The locking member limits the position of the transmitter housing, thereby limiting the relative displacement between the transmitter housing and the sealing member, pressing the sealing member tightly, thereby further improving the sealing effect and preventing contamination inside the transmitter.

[0047] Please refer to Figures 1 to 9 In one embodiment, a transmitter sealing mechanism 100 is provided, which is mainly used to seal the transmitter 200 in the implantation tool to prevent contaminants from entering the interior of the transmitter 200.

[0048] The transmitter sealing mechanism 100 includes a sealing member 10 and a locking member 20. The sealing member 10 abuts against the housing 210 of the transmitter 200 and is located at the pinhole 2101 of the housing 210. In other words, the sealing member 10 abuts against the surface of the housing 210 and is located at the pinhole 2101, thereby shielding the pinhole 2101 and preventing contaminants from entering the transmitter 200 through the pinhole 2101.

[0049] The locking member 20 is connected to the housing 210 to restrict the position of the housing 210 and press the sealing member 10 against the housing 210. In other words, the locking member 20 is connected to the housing 210 to lock and restrict the position of the housing 210, thereby restricting the relative position between the sealing member 10 and the housing 210, making it difficult for the housing 210 and the sealing member 10 to move relative to each other, allowing the sealing member 10 to be pressed tightly against the surface of the housing 210, thereby ensuring the sealing effect of the sealing member 10 on the pinhole 2101.

[0050] Understandably, in the prior art, transmitters require a needle hole to avoid the need for the implant needle. This hole allows contaminants to easily enter the transmitter, contaminating the transmitter's internal structures. In particular, if contaminants enter the transmitter and contaminate the sensor and implant needle, they can easily cause infection when the user uses the implant tool, compromising safety.

[0051] The transmitter sealing mechanism 100 provided in this embodiment can effectively seal and protect the pinhole 2101 of the transmitter 200 through the sealing member 10, and the setting of the locking member 20 can limit the position of the transmitter 200 to avoid relative displacement between the transmitter 200 and the sealing member 10, thereby further ensuring the sealing effect of the sealing member 10.

[0052] It should be noted that, in the implant tool, the sealing member 10 and the locking member 20 can be directly connected; or the sealing member 10 and the locking member 20 can be provided on the same structure; or even the sealing member 10 and the locking member 20 can be provided on different structures. In other words, it is sufficient that the sealing member 10 can seal the pinhole on the transmitter housing, and the locking member 20 can lock the transmitter housing and restrict the position of the transmitter housing to ensure a sealing effect.

[0053] Preferably, in one embodiment, the locking member 20 is movably connected to the housing 210, and has a locked state in which it is connected to the housing 210, and an unlocked state in which it is separated from the housing 210. In the locked state, the locking member 20 restricts the position of the transmitter 200, thereby pressing the sealing member 10 against the housing 210. In other words, the locking member 20 is movable relative to the housing 210, and the relative position between the locking member 20 and the housing 210 can be changed, thereby locking and unlocking the housing 210 to adapt to the use state of the implant tool. For example, when the implant tool is not in use, the locking member 20 is in the locked state, thereby connecting to the housing 210 and restricting the position of the transmitter 200. After the implant tool is in use, the locking member 20 is in the unlocked state, separating from the housing 210, allowing the transmitter 200 to be smoothly placed in the human body.

[0054] Specifically, in one embodiment, the seal 10 is a soft rubber seal, that is, the seal 10 can deform to a certain extent after being subjected to force, thereby better ensuring the sealing effect. More specifically, the seal 10 can be a silicone seal.

[0055] Specifically, in one embodiment, the sealing member 10 is provided with an escape hole 11 opposite to the needle hole 2101, so that the implant needle can escape through the escape hole 11. The sealing member 10 can be an annular sealing member.

[0056] Preferably, in one embodiment, a recessed groove 2102 is defined on the outer surface of the housing 210. In the locked state, the locking member 20 is inserted into the recessed groove 2102. Of course, in other embodiments, in the locked state, the locking member 20 may directly abut against the outer surface (or other structure) of the housing 210 to lock the transmitter 200. In this embodiment, the provision of the recessed groove 2102 provides a more secure connection between the locking member 20 and the housing 210, further ensuring a secure seal. Specifically, in one embodiment, the recessed groove 2102 is defined on the side of the upper housing.

[0057] Specifically, in one embodiment, a hook 21 is provided on the locking member 20 , and in the locking state, the hook 21 is correspondingly inserted into the recessed groove 2102 .

[0058] Preferably, in one embodiment, the transmitter sealing mechanism 100 further includes an elastic member 30 connected to the locking member 20, and the elastic member 30 is used to maintain the locking member 20 in a certain state. The elastic member 30 refers to a component that can undergo elastic deformation when subjected to a force, and can restore to its original position when the force is reduced or disappears. When the locking member 20 is not subjected to other external forces, the locking member 20 can be maintained in a certain state (for example, maintained in the locked state, or maintained in the unlocked state) by the elastic member 30, thereby making the overall structure simpler, and the switching control of the state of the locking member 20 can be achieved without a complex structure, and the state of the locking member 20 can also be maintained stably.

[0059] Specifically, in one embodiment, the elastic member 30 is a spring.

[0060] Specifically, in one embodiment, a support column 22 is provided on the locking member 20, and the support column 22 is inserted into the elastic member 30, so as to better support the elastic member 30 and better guide the force direction between the locking member 20 and the elastic member 30, ensuring that the locking member 20 can smoothly compress the elastic member 30 to the desired state; and during the recovery process of the elastic member 30, the elastic member 30 can be guided in the force direction of the locking member 20 to ensure that the locking member 20 moves to the desired position.

[0061] Preferably, in one embodiment, the transmitter sealing mechanism 100 further includes a limiting member 40, which is configured to abut against and limit the locking member 20, thereby compressing the elastic member 30 and maintaining the locking member 20 in another state. When the elastic member 30 is configured to maintain the locking member 20 in the unlocked state, the limiting member 40 is configured to maintain the locking member 20 in the locked state; when the elastic member 30 is configured to maintain the locking member 20 in the locked state, the limiting member 40 is configured to maintain the locking member 20 in the unlocked state. In other words, the limiting member 40 is configured to squeeze and limit the locking member 20, thereby compressing the elastic member 30 and allowing the locking member 20 to be maintained between states. When the limiting member 40 and the locking member 20 move relative to each other and separate, the locking member 20 loses the limiting resistance applied by the limiting member 40, so that the elastic member 30 can drive the locking member 20 to move through its own elastic restoring force, thereby achieving automatic switching between the two states of the locking member 20. The overall structure is simple and reliable, and the state of the locking member 20 can be controlled by the relative displacement between the limiting member 40 and the locking member 20. The limiting member 40 and the locking member 20 can be arranged on two components of the implant tool that can undergo relative displacement, thereby adapting the control of the state of the locking member 20 to the use state of the implant tool.

[0062] Specifically, in one embodiment, a limiting arm 23 is provided on the locking member 20. In the locked state, the limiting arm 23 is blocked by the limiting member 40, thereby compressing the elastic member 30. In the unlocked state, the limiting arm 23 is located below the limiting member 40, so that the space for the limiting arm 23 to move upward is blocked by the limiting member 40, making it impossible for the locking member 20 to directly return to the locked state, thereby preventing users from using the device twice and ensuring safety.

[0063] Preferably, in one embodiment, there are multiple locking members 20 (at least two are provided), and the locking members 20 are connected to the housing 210 at least from opposite sides of the transmitter 200. That is, when in the locked state, the multiple locking members 20 engage the housing 210 from at least opposite sides of the transmitter 200, thereby better ensuring balanced force on each side of the transmitter 200 and preventing the transmitter 200 from tilting. Specifically, in one embodiment, there are two locking members 20, which engage and lock the housing 210 from opposite sides of the transmitter 200, with the elastic member 30 connected between the two locking members 20. Of course, in other embodiments, the number of locking members 20 may be greater, and the locking members 20 may even be able to lock the transmitter 200 from more angles.

[0064] Preferably, in one embodiment, the locking member 20 is movably disposed on the ejection member 300 of the implantation tool so as to connect the ejection member 300 to the launcher 200 in the locked state. That is, in this embodiment, the locking member 20 is used to connect the ejection member 300 to the launcher 200. By moving the locking member 20 relative to the ejection member 300, the state of the locking member 20 is changed, thereby achieving locking, fixing, or separation between the ejection member 300 and the launcher 200. By movably disposing the locking member 20 on the ejection member 300, an additional connecting structure is no longer required between the ejection member 300 and the launcher 200, and the locking member 20 can more stably secure the launcher 200 to the ejection member 300.

[0065] Preferably, in one embodiment, the seal 10 is provided on the implant needle assembly 400 of the implant tool. That is, in this embodiment, the seal 10 and the locking member 20 are provided on different structures, and in the implant tool, the implant needle assembly 400 is snapped onto the ejection member 300. In this way, while the locking member 20 locks the transmitter 200 onto the ejection member 300, the implant needle assembly 400 also limits the position of the seal 10, thereby ensuring the sealing effect. By directly providing the seal 10 on the implant needle assembly 400, the overall structure can be simplified and the sealing effect can be improved. Specifically, in one embodiment, the seal 10 is provided at the bottom of the needle head 410 of the implant needle assembly 400.

[0066] Preferably, in one embodiment, when in the locked state, the locking member 20 is further inserted into the implant needle assembly 400 to limit the position of the implant needle assembly 400. That is, in this embodiment, when in the locked state, a portion of the locking member 20 extends into the implant needle assembly 400, thereby limiting the position of the implant needle assembly 400. Because the locking member 20 is also connected to the transmitter 200 in the locked state, the relative position of the transmitter 200 and the implant needle assembly 400 is restricted, thereby ensuring compression of the seal 10 and further ensuring a sealing effect. Furthermore, because the locking member 20 limits the position of the implant needle assembly 400, the locking member 20 must be separated and unlocked from the implant needle assembly 400 before the implant needle assembly 400 can be withdrawn. This further ensures that when the implant tool is used, the transmitter 200 is unlocked before the needle is withdrawn. When the locking member 20 is disposed on the ejection member 300 , this structure can also better ensure the stability of the implant needle assembly 700 being locked on the ejection member 300 .

[0067] Specifically, in one embodiment, the movable direction of the locking member 20 is perpendicular to the arrangement direction of the implant needle assembly 400. Figure 1 In the embodiment shown, the locking member 20 is movable in the horizontal direction, while the implant needle assembly 400 is arranged in the vertical direction. The locking member 20 locks and unlocks the implant needle assembly 400 by moving in the horizontal direction, thereby improving the locking effect of the implant needle assembly 400.

[0068] More specifically, in the implantation tool, when the implantation tool is in use, the movement direction of the transmitter 200 is vertically downward, and the withdrawal direction of the implantation needle assembly 400 is vertically upward.

[0069] Specifically, in one embodiment, a card slot 4101 is provided on the needle 410 , and a card arm 24 is provided on the locking member 20 . In the locking state, the card arm 24 is inserted into the card slot 7201 .

[0070] Preferably, in one embodiment, the transmitter sealing mechanism 100 further includes a sealing sleeve 50, which is detachably connected to the bottom of the housing 210 and seals the pinhole 2101 at the bottom of the housing 210. The sealing member 10 is located at the top of the housing 210. That is, in this embodiment, the sealing member 10 only seals the pinhole 2101 at the top of the transmitter 200, while the pinhole 2101 at the bottom of the transmitter 200 is sealed by the sealing sleeve 50. The provision of the sealing sleeve 50 allows the sealing sleeve 50 to be removed before using the implant tool, thereby preventing the subsequent attachment of the transmitter 200 to the human body. Furthermore, the sealing sleeve 50 can also support and limit the position of the transmitter 200 within the implant tool, thereby better preventing the implant tool from accidentally falling and affecting its use. The locking member 20 cooperates with the sealing member 10 to seal the top of the transmitter 200, and the sealing sleeve 50 seals the bottom of the transmitter 200, thereby improving the sealing effect. Due to the improved sealing effect, the transmitter 200 no longer needs to be equipped with additional sealing components such as silicone, which simplifies the internal structure of the transmitter 200 and reduces the difficulty of assembling the transmitter 200.

[0071] More preferably, in one embodiment, an elastic seal 51 abutting against the bottom of the shell 210 is provided inside the sealing sleeve 50. The sealing sleeve 50 presses the elastic seal 51 against the bottom of the shell 210, thereby further improving the sealing effect.

[0072] In one embodiment, an implantation tool 1000 is also provided, comprising a housing 500, an ejection member 300, a transmitter assembly, a driver 600, a drive spring 700, an implant needle assembly 400, and the transmitter sealing mechanism 100. The ejection member 300 is snap-fitted into the housing 500, where "snap-fit" refers to a connection between one component and another via a corresponding snap-fit structure, and the two components can be separated from each other under corresponding conditions. The transmitter assembly is disposed on the ejection member 300. The driver 600 is disposed in the housing 500 to drive the ejection member 300 to release. The drive spring 700 is disposed between the housing 500 and the ejection member 300 to drive the ejection member 300 to move. The implant needle assembly 400 is snap-fitted into the ejection member 300. The sealing member 10 abuts against the housing 210 of the transmitter 200 in the transmitter assembly, and the locking member 20 is connected to the housing 210. When in use, the user operates the driving member 600 to release the ejection member 300, so that the driving spring 700 drives the ejection member 300 to move, and the ejection member 300 drives the emitter assembly to move synchronously, thereby achieving the implantation operation.

[0073] Specifically, in one embodiment, the transmitter assembly includes the transmitter 200 and the sensor 800 .

[0074] Preferably, in one embodiment, the locking member 20 is movably disposed on the ejection member 300, and the transmitter assembly is connected to the ejection member 300 via the locking member 20. When the implant tool 1000 is not in use, the locking member 20 is in the locked state, and the locking member 20 is connected to the housing 210, thereby fixing the transmitter assembly to the ejection member 300. When the implant tool 1000 is used, the locking member 20 is separated from the housing 210 and is in the unlocked state, thereby disengaging the transmitter assembly from the ejection member 300.

[0075] Preferably, in one embodiment, the limiting member 40 is provided on the housing 500. When the implant tool 1000 is not in use, the limiting member 40 squeezes and limits the locking member 20, thereby compressing the elastic member 30, allowing the locking member 20 to remain in the locked state and fix the transmitter assembly. When the user manipulates the driving member 600 to release the ejection member 300, the locking member 20 moves along with the ejection member 300, thereby causing the locking member 20 and the limiting member 40 to undergo relative displacement. After moving to a certain distance, the locking member 20 separates from the limiting member 40, and the elastic member 30 stretches, thereby driving the locking member 20 to convert to the unlocked state, causing the transmitter assembly to detach from the ejection member 300.

[0076] Preferably, in one embodiment, the implant needle assembly 400 includes a needle 410, an implant needle 420, a needle cap 430, and a needle withdrawal spring 440. The implant needle 420 is connected to the needle 410 and passes through the emitter assembly. The needle cap 430 is connected to the needle 410, and the needle withdrawal spring 440 is disposed between the needle cap 430 and the ejection member 300. When the implant tool 1000 is not in use, the elastic arm 310 on the ejection member 300 squeezes and limits the needle cap 430, thereby snapping the needle cap 430 onto the ejection member 300 and compressing the needle withdrawal spring 440. After the implantation tool 1000 is used, the ejection member 300 moves a certain distance, and the implantation needle 420 penetrates the skin. The needle withdrawal spring 440 extends, driving the needle cap 430 to separate from the ejection member 300, thereby driving the implantation needle 420 to retract, completing the needle withdrawal operation. The sealing member 10 is provided at the bottom of the needle 410 to improve the sealing effect of the transmitter 200 when the implantation tool 1000 is not in use.

[0077] More preferably, in one embodiment, the limiting member 40 is further configured to squeeze and limit the elastic arm 310. When the implant tool 1000 is not in use, the limiting member 40 squeezes and limits the elastic arm 310, leaving no room for the elastic arm 310 to retreat. This forces the elastic arm 310 to squeeze and limit the needle cap 430, compressing the needle withdrawal spring 440. When the user manipulates the driving member 600 to disengage the ejection member 300, the elastic arm 310 moves with the ejection member 300. After moving a certain distance, the elastic arm 310 separates from the limiting member 40, allowing the elastic arm 310 to retreat. At this point, the needle withdrawal spring 440 extends, driving the needle cap 430 to retreat, thereby driving the implant needle 420 to retreat, completing the needle withdrawal operation.

[0078] In the implantation tool 1000, the transmitter 200 has only a small needle hole 2101, which enhances the aesthetics of the transmitter 200. The locking member 20 and the sealing member 10 protect the implantation needle 420 and the sensor 800 prior to implantation, preventing them from being contaminated or damaged by foreign objects. This seal also protects the implantation needle 420 and the sensor 800 from the outside world before implantation. As long as the locking member 20 remains attached, the sealing function ensures that the implantation needle 420 and the sensor 800 remain sealed. Furthermore, during the production and assembly process, the locking member 20 can be sterilized by gamma ray and transported without becoming loose.

[0079] The above is only an embodiment of the present invention. It should be pointed out that those skilled in the art can make improvements without departing from the inventive concept of the present invention, but these improvements are all within the scope of protection of the present invention.
