Component 38 is located between the implantable fixation bracket 37 and the implantable transmitting bracket 36; the transmitting button assembly is located at the end furthest from the implantation site and is in contact with the implantable fixation bracket 37; pressing the transmitting button assembly along the implantation direction disengages the implantable transmitting bracket 36 from the implantable fixation bracket 37, and the transmitting drive component 38 drives the return needle assembly 58 to move along the implantation direction, allowing the sensor 57 of the transmitter 56 to be implanted into the human body. Simultaneously, the return needle drive component 35 drives the return needle cap 34 to move the guide needle structure 59 of the transmitter 56 in the opposite direction to the implantation direction to achieve return needle movement. During reset, pressing the implantable transmitting bracket 36 in the opposite direction to the implantation direction and pressing the transmitting button assembly along the implantation direction resets the return needle cap 34 and the implantable transmitting bracket 36. The implanter in this embodiment can be reset without disassembly, facilitating the testing of the implanter's effectiveness during production, enabling implanter reuse, saving costs, and reducing medical waste.
[0069] In this embodiment, the implantation direction refers to the direction in which the sensor 57 is implanted into the human body by the dynamic blood glucose meter 100.
[0070] In some embodiments, the needle cap 34 includes a needle cap body 39 and a needle support 40. The needle support 40 is disposed on the needle cap body 39 and extends in the opposite direction to the implantation direction. The needle cap body 39 is provided with a limiting part for limiting the needle seat of the transmitter 56. The needle support 40 is provided with a connecting buckle 41.

The inner wall of the implantation fixation support 37 is provided with an implantation fixation buckle 44 adapted to the implantation transmitter hole 43. The implantation fixation buckle 44 can engage with the implantation transmitter hole 43.
[0071] In some embodiments, a return needle buckle 45 is provided at the end of the return needle bracket 40. The return needle buckle 45 is located at the end of the return needle bracket 40 near the transmitter button assembly. The position of the return needle buckle 45 corresponds to the connecting buckle 41, and the number of return needle buckles 45 is the same as the number of connecting buckles 41. The implantation fixation bracket 37 is provided with a return needle opening 46 for the return needle buckle 45 to pass through. The return needle buckle 45 is inclined from the outside to the inside in the direction from the transmitter button assembly to the implantation position in the human body. The inclined surface at the return needle opening 46 matches the return needle buckle 45. When the transmitter 56 is implanted in the human body, the return needle buckle 45 is located in the return needle opening 46, the return needle bracket 40 contracts and deforms inward, the connecting buckle 41 separates from the implantation transmitter slot 42, and the return needle driving element 35 drives the return needle cap 34 to drive the guide needle structure 59 of the transmitter 56 to move in the opposite direction to the implantation.
[0072] In some embodiments, the number of implantable transmitter slots 42 and implantable transmitter holes 43 are the same, and the implantable transmitter slots 42 and implantable transmitter holes 43 are alternately arranged around the axis of the implantable transmitter bracket 36, so that the structure is subjected to uniform stress.
[0073] In some embodiments, the implantable transmitter scaffold 36 is provided with a limiting buckle structure, the limiting buckle structure is provided with a limiting buckle, there is a gap between the limiting buckle and the implantable transmitter scaffold 36, or the limiting buckle is made of an elastic material, the limiting buckle is used to limit the transmitter 56, the limiting buckle is inclined from the outside to the inside in the direction from the transmitter button assembly toward the implantation position in the human body, and the limiting groove 60 of the transmitter housing of the transmitter 56 is provided with an inclined surface that matches the limiting buckle.
[0074] In some embodiments, the transmitting button assembly includes a button driving element 47, a transmitting button 48, and a button cap 49. The button cap 49 is detachably connected to the housing 33. Rotating the button cap 49 connects the button cap 49 to the housing 33, while rotating it in the opposite direction separates the button cap 49 from the housing 33. The button cap 49 encloses the button and the button driving element 47 in the space formed by the button cap 49 and the housing 33. The transmitting button 48 is snapped into the housing 33. The button driving element 47 is preferably a button compression spring, which is located between the transmitting button 48 and the housing 33. The transmitting button 48 contacts the implanted fixation bracket 37.
[0075] In some embodiments, the launch button 48 is provided with a launch trigger latch 50, and the implantation fixation bracket 37 includes an implantation fixation body 51 and a trigger bracket 52. The trigger bracket 52 is disposed on the implantation fixation body 51, and the return needle opening 46 is disposed on the implantation fixation body 51. The trigger bracket 52 extends in the opposite direction to the implantation direction. The implantation fixation latch 44 is located inside the trigger bracket 52, and the end of the trigger bracket 52 is provided with an implantation trigger latch 53. The implantation trigger latch 53 is disposed at the end of the trigger bracket 52 near the launch button assembly. The implantation trigger latch 53 is inclined from the outside to the inside in the direction from the launch button assembly toward the implantation position in the human body. The inclined surface of the launch trigger latch 50 matches the implantation trigger latch 53. When the launch button 48 is triggered, the launch trigger latch 50 moves and enters the implantation fixation bracket 37 to open the trigger bracket 52, thereby separating the implantation fixation latch 44 of the implantation fixation bracket 37 from the implantation launch hole 43 of the implantation launch bracket 36, causing the launch drive element 38 to move and push the return needle assembly 58 to move.
[0076] In some embodiments, a transmitter limiting bracket 54 is also included. The transmitter limiting bracket 54 is located in the housing 33 and is engaged with the side of the implanted transmitter bracket 36 closest to the human body. The transmitter limiting bracket 54 is used to limit the transmitter 56. When the transmitter 56 fires, the driving force of the firing drive element 38 can separate the transmitter 56 from the transmitter limiting bracket 54.
[0077] In some embodiments, the housing 33 also includes a protective cap 55, which is detachably connected to the housing 33. The protective cap 55 is provided with a placement groove for placing a protective sleeve for the sensor 57. The protective cap 55 and the protective sleeve 25 are detachably connected. When the protective cap 55 and the protective sleeve 25 are connected, the protective cap 55 and the protective sleeve 25 form a whole. When the sensor 57 needs to be implanted, the protective cap 55 is separated from the housing 33, and the protective sleeve 25 can be separated from the transmitter 56 at the same time. That is, the protective cap 55 and the protective sleeve 25 can be removed at the same time without removing the protective sleeve 25 separately, and the guide pin part 20 of the guide pin structure 59 can be directly seen.
[0078] The operation process of the implanter in this embodiment is as follows: Open the button cap 49, press the launch button 48. The launch trigger latch 50 of the launch button 48 opens the trigger bracket 52 of the implantation fixation bracket 37, causing the implantation fixation latch 44 of the implantation fixation bracket 37 to separate from the implantation launch hole 43 of the implantation launch bracket 36. The launch drive element 38 moves, driving the return needle assembly 58 to move. The return needle assembly 58 drives the transmitter 56 to move, causing the sensor 57 of the transmitter 56 to be implanted into the human body. When the patch contacts and adheres to the human skin, the implanter is removed. The adhesive force between the patch and the human skin allows the transmitter 56 to break free from the limiting latch of the implantation launch bracket 36, allowing the implanter to separate from the transmitter 56. Simultaneously with the implantation of the transmitter 56 into the human body… The return needle buckle 45 is located in the return needle opening 46. The return needle bracket 40 retracts and deforms inward. The connecting buckle 41 separates from the implantation emitter slot 42. The return needle driving element 35 drives the return needle cap 34 to move the guide needle structure 59 of the transmitter 56 in the opposite direction to the implantation, thus realizing the return needle. When it is necessary to reset the implanter, press the implantation emitter bracket 36 into the implantation fixation bracket 37, so that the implantation fixation buckle 44 of the implantation fixation bracket 37 engages with the implantation emitter slot 43 of the implantation emitter bracket 36. At this time, without releasing the hand, press the launch button 48 with the other hand, so that the connecting buckle 41 of the return needle cap 34 engages with the implantation emitter slot 42 of the implantation emitter bracket 36. Then release the launch button 48, and the launch button 48 is reset under the action of the button driving element 47.
[0079] The implanter in this embodiment has a simple structure, a high implantation success rate, and can be reset without disassembly. This facilitates the testing of the implanter's effectiveness during the production process, makes the implanter reusable, saves costs, and reduces medical waste.

[0093] In this embodiment, the transmitter 56 ensures the stable installation of the sensor 57, reducing the risk of pulling the sensor 57 out during pin retraction. Due to the stable installation of the sensor 57, the circuit board 31 only needs to connect to the sensor 57 via the 3-pin socket 26. Of the three spring pins 61 in the 3-pin socket 26, one spring pin 61 is located on one side of the sensor 57 and on the line of symmetry of the other two spring pins 61. The other two spring pins 61 are located on the other side of the sensor 57. The three spring pins 61 are arranged in an isosceles triangle. Figure 43As shown, the prior art sensor 62 is not securely installed, so it needs to be balanced by a 4-pin socket. Of the four spring pins 61 of the 4-pin socket, two spring pins 61 are located on one side of the prior art sensor, and the other two spring pins 61 are located on the other side of the prior art sensor 62. Compared with the prior art, this embodiment reduces costs; and the compression part 22 of the lower housing 12 can ensure that the implanted structure 1 is effectively wrapped by the guide pin structure 59; the foolproof design of the transmitter housing can facilitate the quick installation of the transmitter 56.
[0094] like Figures 4 to 10 As shown, the installation process of the dynamic blood glucose meter 100 in this embodiment is as follows: the needle return drive element 35 is placed into the needle return cap 34, and then pressed into the implanter transmitter bracket. The transmitter drive element 38 is then placed on the implanter transmitter bracket. The implanter transmitter bracket 36 and the implantation fixation bracket 37 are then connected. The implantation assembly and the needle return assembly 58 are then installed as a whole into the housing 33. The implantation fixation bracket 37 is fixedly connected to the housing 33. The transmitter button assembly is then installed at the top of the housing 33. The transmitter limiting bracket 54 is then installed at the bottom of the housing 33. The transmitter 56 is then installed. Finally, the protective cap 55 of the housing 11 is installed.
