In addition, the terms "first", "second" and "third" are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", and "third" may explicitly or implicitly include one or at least two of such features. The term "proximal end" generally refers to the end closer to the operator, and the term "distal end" generally refers to the end closer to the patient, i.e., the end closer to the lesion. "One end" and "the other end" as well as "proximal end" and "distal end" generally refer to two corresponding parts, which include not only endpoints. The terms "installed", "connected", and "connected" should be understood in a broad sense. For example, they can be fixedly connected, detachably connected, or integrated; they can be mechanically connected or electrically connected; they can be directly connected or indirectly connected through an intermediate medium; they can be internal communication between two elements or an interactive relationship between two elements. In addition, as used in the present invention, "one element is arranged on another element" generally only means that there is a connection, coupling, cooperation, or transmission relationship between the two elements, and the connection, coupling, cooperation, or transmission between the two elements can be direct or indirect through an intermediate element, and it should not be understood to indicate or imply a spatial positional relationship between the two elements, that is, one element can be in any orientation such as inside, outside, above, below, or to the side of another element, unless the content clearly indicates otherwise. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0110] The purpose of the present invention is to provide an implanter, a needle assembly, a sensor base assembly, a transmitter assembly, a sterilization box and an implantation system to solve the problems of high cost and environmental impact of existing disposable implantation devices.

[0111] like Figure 1As shown, an embodiment of the present invention provides an implantation system, which includes: an implanter 100, a sterilization box assembly 210, a transmitter assembly 300, a needle assembly 230, and a sensor base assembly 220. In an initial state, the needle assembly 230 and the sensor base assembly 220 can be accommodated in the sterilization box assembly 210 to form a sterilization box assembly 200. During use, the implanter 100 is inserted into the sterilization box assembly 210, and the needle assembly 230 and the sensor base assembly 220 are loaded into the implanter 100. The implanter 100 is then used to implant the needle assembly 230 and the sensor base assembly 220 into a predetermined implantation site of a target object. The implanter 100 and the needle assembly 230 are then removed, while the sensor base assembly 220 remains at the predetermined implantation site. The transmitter assembly 300 is then assembled onto the sensor base assembly 220 to complete the implantation process.

[0112] The following, in conjunction with the accompanying drawings, illustrates the steps for using the implant system provided in this embodiment. The steps for using the implant system primarily include a grasping step, a releasing step, a separating step, a combining step, and a recovering step. It should be noted that the components involved in each of the following steps will be described and explained in detail later.

[0113]

Crawling steps

[0114] After tearing off the cover 212 and the top protective cover 213, the needle assembly 230 and the sensor base assembly 220 are exposed;

[0115] State of the implanter 100: Move the implanter 100 in the direction from the second end 101b to the first end 101a (i.e. Figure 3 The direction of the up-down arrangement in the sterilization box 200) is toward the bottom direction (i.e. Figure 2 The implanter 100 is then pushed toward the bottom of the sterilization box 200, and the ejection assembly 111 is moved toward the first end 101a of the base 101 by the reaction force of the boss inside the sterilization box shell 211 (i.e., the ejection assembly 111 is pushed upward), until the ejection assembly 111 reaches the first predetermined position, and the second potential energy portion 132 releases the potential energy, so that the ejection assembly 111 is engaged and limited by the first limiting portion 1014, as shown in FIG. Figure 7 and Figure 8 During this process, the first potential energy unit 112 stores potential energy.

[0116] State of the needle assembly 230: When the needle assembly 230 is inserted into the ejection assembly 111 and the implanter 100 is continuously pushed toward the bottom of the sterilization box 200, the needle assembly 230 gradually moves toward the first end 101a until it reaches the third predetermined position and is engaged and limited by the third limiting portion 141 (specifically, the seventh limiting portion 2512 is engaged and limited by the limiting platform 1412). Figure 7 As shown. During this process, the third potential energy portion 142 stores potential energy. It should be noted that the needle assembly 230 can reach the third predetermined position before the ejection assembly 111 moves relative to the first end 101a of the base 101, after the ejection assembly 111 has moved to the first predetermined position, or between the two positions.

[0117] The state of the sensor base assembly 220: The sensor base assembly 220 is initially assembled with the needle assembly 230, and the first engaging portion 2521 is engaged with the second engaging portion 2222. Figure 12 For further information, please refer to Figure 4 and Figure 8 As ejection assembly 111 moves toward first end 101a of base 101, fifth position-limiting portion 121 gradually moves inward, constrained by fourth slope 1016 and / or fifth slope 1211. This movement pushes fourth potential energy portion 122 to store potential energy. When ejection assembly 111 reaches the first predetermined position, sensor base assembly 220 is additionally restrained, ensuring that after needle assembly 230 and sensor base assembly 220 are loaded into implanter 100, sensor base assembly 220 does not escape from implanter 100.

[0118] Finally, if Figure 7 and Figure 8 As shown, the implanter 100 performs a grabbing operation on the sensor base assembly 220 and the needle assembly 230 .

[0119]

Release steps

[0120] Status of implanter 100: will be in Figure 7 and Figure 8 The assembly in the state shown is moved to the predetermined implantation site, the pressing portion 102 is pressed, and the second limiting portion 131 is pushed toward the center. The first limiting portion 1014 releases the restriction on the ejection assembly 111, and the first potential energy portion 112 releases the potential energy to drive the ejection assembly 111 toward the second end 101b until the ejection assembly 111 moves to the fifth predetermined position and is limited by the fourth limiting portion 1011 (see FIG. Figure 6 、 Figure 7 ), the implanter 100 is as follows Figure 9 and Figure 10In addition, during this process, the fourth potential energy portion 122 releases potential energy, pushing the fifth limiting portion 121 to move outward, thereby releasing the additional limit on the sensor base assembly 220 .

[0121] The state of the needle assembly 230: the needle assembly 230 continues to maintain the relative connection relationship with the ejection assembly 111 unchanged, and is ejected as the ejection assembly 111 is ejected, and the needle assembly 230 drives the sensing portion 221 of the sensor base assembly 220 to penetrate the skin of the predetermined implantation site.

[0122] Status of the sensor base assembly 220: The sensor base assembly 220 continues to maintain a relative connection relationship with the needle assembly 230, and the adhesive layer 223 is adhered to the surface of the predetermined implantation site, that is, in contact with the skin.

[0123]

Separation steps

[0124] Please refer to Figures 14 to 16 The implanter 100 is lifted toward the first end 101a (i.e., upward in the figure). The ejection assembly 111 is restrained in the base 101 by the fourth limiting portion 1011, and the needle assembly 230 is restrained in the ejection assembly 111 by the third limiting portion 141. Thus, the implanter 100 and the needle assembly 230 are lifted together.

[0125] The adhesive layer 223 of the sensor base assembly 220 is attached to the skin surface. Since the connection between the sensor base assembly 220 and the needle assembly 230 is achieved by the first engaging portion 2521 and the second engaging portion 2222 (see FIG. Figure 12 and Figure 13 ), the two are axially separable, so the sensor base assembly 220 will not be lifted together with the implanter 100 and the needle assembly 230, but will be separated from the needle assembly 230.

[0126] For further information, please refer to Figure 13 , the needle assembly 230 is in the housing 251 (such as Figure 11 ) is separated from the sensor base assembly 220, the seventh potential energy portion 252 releases potential energy, driving the sixth limiting portion 2523 to release the movement restriction of the needle body 263, and then the sixth potential energy portion 262 releases potential energy, driving the needle body 263 toward the direction away from the opening end of the housing 251 (i.e., driving the needle body 263 toward Figure 13 The needle body 263 is moved upward in the housing 251 to avoid scratching the operator.

[0127]

Combination steps

[0128] Please refer to Figures 17 to 21After the sensor base assembly 220 is separated from the needle assembly 230, the emitter assembly 300 is snapped onto the sensor base assembly 220, so that the sensing part 221 of the sensor base assembly 220 is electrically connected to the emitter assembly 300, thereby realizing the assembly combination of the sensor base assembly 220 and the emitter assembly 300.

[0129]

Recycling steps

[0130] Please refer to Figures 28 to 31 After the sensor base assembly 220 is separated from the needle assembly 230, the sterilization box assembly 210 is turned upside down so that the needle withdrawal component 2111 is convex upward; then the implanter 100 is moved toward the direction of the needle withdrawal component 2111 (i.e. Figure 28 The needle-retracting component 2111 pushes the third limiting portion 141 toward the outside of the ejection component 111 ( Figure 31 The right side of the third limiting portion 141 moves so that the limiting platform 1412 of the third limiting portion 141 is released from the seventh limiting portion 2512 (see Figure 11 ), the needle assembly 230 can be released from the ejection assembly 111 under the action of gravity and fall into the sterilization box assembly 210, thereby achieving the separation of the needle assembly 230, so that the implanter 100 can be reused. It can be understood that the recovery step is an optional step.

[0131] The components of the implant system are described in detail below with reference to the accompanying drawings.

[0132] Please refer to Figure 2 In an alternative embodiment, the sterilization box assembly 210 includes a sterilization box housing 211, a cover 212, and a top protective cover 213. The sterilization box housing 211 defines a first accommodation space, and the needle assembly 230 and the sensor base assembly 220 are placed in the first accommodation space within the sterilization box housing 211 after assembly. The cover 212 is sealed to the sterilization box housing 211 (preferably, the cover 212 is heat-sealed to the sterilization box housing 211 using hot melt adhesive, and the sterilization box is sterilized by irradiation after packaging), thereby forming a sealed first accommodation space. The top protective cover 213 is bonded to the inner surface of the cover 212 and is used to restrict movement of the needle assembly 230 and the sensor base assembly 220. During use, the top protective cover 213 can be removed along with the cover 212, revealing the needle assembly 230 and the sensor base assembly 220 assembled in the first accommodation space. Of course, in some other embodiments, it is not limited to that both the needle assembly 230 and the sensor base assembly 220 are placed in the sterilization box assembly 210 , and only one of them may be placed in the sterilization box assembly 210 .

[0133] Please refer to Figures 3 to 6This embodiment provides an implanter 100, which includes: a base 101, a pressing portion 102, an ejection assembly 111 and a first potential energy portion 112; the base 101 is axially ( Figure 3 The ejection assembly 111 is movably arranged along the axial direction of the base 101; the ejection assembly 111 is used to connect with the needle assembly 230 and to be detachably connected with the sensor base assembly 220; the first potential energy portion 112 stores potential energy during the movement of the ejection assembly 111 toward the first end 101a; the ejection assembly 111 moves toward the first end 101a to exceed the first predetermined position (please refer to Figure 7 and Figure 8 , wherein the ejection assembly 111 is located at the first predetermined position), it is restricted by the first limiting portion 1014, thereby preventing the ejection assembly 111 from moving toward the second end 101b; after the pressing portion 102 is pressed, the restriction of the first limiting portion 1014 on the ejection assembly 111 is released, and the first potential energy portion 112 releases potential energy to drive the ejection assembly 111 toward the second end 101b, thereby driving the needle assembly 230 and the sensor base assembly 220 to move toward the second end 101b, that is, driving the needle assembly 230 and the sensor base assembly 220 to be launched toward the predetermined implantation site. With this configuration, since the needle assembly 230 and the sensor base assembly 220 are detachable, the implanter 100 and the needle assembly 230 can be removed after the implantation is completed so that the implanter 100 can be reused. The implant portion only includes the sensor base assembly 220, and the implanter 100 can be recycled and used multiple times, effectively reducing costs and reducing the impact on the environment. It should be noted that the first potential energy portion 112 here may include elastic potential energy components (such as springs, springs, elastic plastic parts, etc.), and may also include magnetic potential energy components (such as magnets, iron parts), etc., and this embodiment is not limited to this. Figure 3 and Figure 4 In the illustrated example, the first potential energy portion 112 includes a spring, one end of which is connected to the base 101 and the other end is connected to the ejection assembly 111. When the ejection assembly 111 moves toward the first end 101a, the spring is compressed and stores potential energy. In other embodiments, magnetic components can also be used to store potential energy. The second potential energy portion, third potential energy portion, fourth potential energy portion, fifth potential energy portion, sixth potential energy portion, seventh potential energy portion, and eighth potential energy portion described below can all refer to the above description of the first potential energy portion 112 and store and release potential energy in various suitable ways. The present invention is not limited to this and will not be further described below.

[0134] Please refer to Figure 6 and Figure 7In an alternative exemplary embodiment, the base 101 has four elastic arms 1015 arranged along its own axial direction, with the end of the elastic arm 1015 near the second end 101b being a free end; every two elastic arms 1015 are spaced apart from each other to form a slide 1012 extending in a direction parallel to the axial direction of the base 101. Correspondingly, the ejection assembly 111 has two slides 1111, which are respectively accommodated in two slides 1012 and are restricted by the slides 1012 in all degrees of freedom except along the axial direction of the base 101. As a result, the ejection assembly 111 is restricted by the slides 1111 and the slides 1012 and can only move along the axial direction of the base 101 and cannot escape from the base 101.

[0135] Optionally, the ejection assembly 111 includes: a second limiting portion 131 and a second potential energy portion 132; the second limiting portion 131 is movably arranged along the radial direction of the base 101; the second potential energy portion 132 stores potential energy during the process of the ejection assembly 111 moving along the second end 101b toward the first end 101a; after the ejection assembly 111 moves toward the first end 101a to exceed the first predetermined position, the second potential energy portion 132 releases potential energy and drives the second limiting portion 131 to move along the radial direction of the base 101 to the second predetermined position (please refer to Figure 8 , wherein the second limiting portion 131 is located at the second predetermined position); the second limiting portion 131 at the second predetermined position is used to abut against the first limiting portion 1014 to limit the movement of the ejection assembly 111 toward the second end 101b. Please refer to Figure 4 In one exemplary embodiment, the second limiting portion 131 includes two spaced-apart sub-limiting blocks, and the second potential energy portion 132 includes a spring disposed between the two sub-limiting blocks. The first limiting portion 1014 includes a radially extending boss. After the ejection assembly 111 moves toward the first end 101a beyond the first predetermined position, the spring of the second potential energy portion 132 releases its potential energy, pushing the two sub-limiting blocks of the second limiting portion 131 outward to the second predetermined position. The sub-limiting blocks then abut against the boss of the first limiting portion 1014 on a radial plane, thereby limiting the movement of the ejection assembly 111 toward the second end 101b and maintaining the ejection assembly 111 within the first predetermined position.

[0136] When the ejection assembly 111 is located at the first predetermined position and the second potential energy portion 132 is located at the second predetermined position, the pressing portion 102 is pressed, driving the second limiting portion 131 to move radially along the base 101 and leave the second predetermined position to release the abutment between the second limiting portion 131 and the first limiting portion 1014. The pressing portion 102 can be formed on the base 101, with one end fixedly connected to the base 101 and the other end being a free end, which can be pressed by the operator to move radially along the base 101. The inner side of the pressing portion 102 can drive the two sub-limiting blocks of the second limiting portion 131 to move inward by abutting against each other until the sub-limiting blocks are released from the abutment against the boss of the first limiting portion 1014, and the spring of the first potential energy portion 112 releases the potential energy, driving the ejection assembly 111 to eject toward the second end 101b in an instant, driving the needle assembly 230 and the sensor base assembly 220 to be ejected toward the predetermined implantation site (see Figure 9 and Figure 10 ).

[0137] Please refer to Figure 8 The base 101 includes a first slope 1013 inclined inwardly toward the second end 101b; and / or the second limiting portion 131 includes a second slope 1311 inclined outwardly toward the first end 101a; during the movement of the ejection assembly 111 toward the first end 101a, the second limiting portion 131 gradually moves inwardly along the radial direction of the base 101 under the restriction of the first slope 1013 and / or the second slope 1311, and drives the second potential energy portion 132 to store potential energy.

[0138] It should be noted that the first slope 1013 is inwardly inclined toward the second end 101b, which means that the first slope 1013 is formed on the inner side of the base 101, facing the interior of the base 101 (i.e., the central axis), and the normal of the first slope 1013 is facing the direction of the second end 101b, so that the distance between the side of the first slope 1013 close to the second end 101b and the axis of the base 101 is greater than the distance between the side of the first slope 1013 close to the first end 101a and the axis of the base 101.

[0139] The outward inclination of the second slope 1311 toward the first end 101a can be understood by referring to the inward inclination of the first slope 1013 toward the second end 101b described above. Specifically, the second slope 1311 is formed on the outside of the second limiting portion 131, facing outward (i.e., away from the central axis) of the base 101, and the normal of the second slope 1311 faces toward the first end 101a, so that the distance between the side of the second slope 1311 closer to the second end 101b and the axis of the base 101 is greater than the distance between the side of the second slope 1311 closer to the first end 101a and the axis of the base 101. The inward and outward inclination of other components below can also be understood by referring to this and will not be described in detail.

[0140] exist Figure 4 In the illustrated example, the base 101 includes two first sloped surfaces 1013 disposed opposite each other, and the two sub-limiting blocks of the second limiting portion 131 each have a second sloped surface 1311. The first sloped surface 1013 and the second sloped surface 1311 are both shaped to be smaller at the top and larger at the bottom. In particular, the first sloped surface 1013 and the second sloped surface 1311 can be flat, curved, or have multiple folded surfaces, and this is not limited in this embodiment. It is understood that in some embodiments, only the first sloped surface 1013 or the second sloped surface 1311 can be provided, while the other is a surface parallel to the axial direction of the base 101, and the same effect can be achieved. The provision of the first sloped surface 1013 and / or the second sloped surface 1311 allows the ejection assembly 111 to move toward the first end 101a, and the two sub-limiting blocks of the second limiting portion 131 are gradually squeezed and moved inward, thereby driving the second potential energy portion 132 to store potential energy.

[0141] Please refer to Figure 3 、 Figure 4 、 Figure 6 and Figure 7 Preferably, the base 101 includes a fourth limiting portion 1011; the fourth limiting portion 1011 is used to limit the movement of the ejection assembly 111 toward the second end 101b to not exceed a fifth predetermined position (please refer to Figure 3 and Figure 4 , wherein the ejection assembly 111 is located at the fifth predetermined position). Optionally, the fourth limiting portion 1011 is located at the end of the elastic arm 1015 near the second end 101b. The fourth limiting portion 1011 can be a hook provided on the elastic arm 1015, and its end facing the first end 101a has a limiting platform. The fourth limiting portion 1011 can limit the movement of the ejection assembly 111 toward the second end 101b to no more than the fifth predetermined position by abutting against the slide 1111, thereby preventing the ejection assembly 111 from escaping from the base 101.

[0142] exist Figure 1In the implant system shown, the needle assembly 230 and the sensor base assembly 220 are initially housed in the sterilization box assembly 210. During use, the needle assembly 230 and the sensor base assembly 220 are loaded together into the ejection assembly 111 of the implanter 100. In this case, the ejection assembly 111 and the needle assembly 230 are relatively detachably and movably connected. Figure 7 and Figure 8 , the second end 101b of the implanter 100 is pressed down toward the needle assembly 230 and the sensor base assembly 220. In contrast, the needle assembly 230 and the sensor base assembly 220 move toward the first end 101a, driving the ejection assembly 111 to move relative to the first end 101a until it reaches or exceeds the first predetermined position. During this process, the needle assembly 230 and the sensor base assembly 220 also move relative to the ejection assembly 111 toward the first end 101a until the needle assembly 230 reaches the third predetermined position (see Figure 7 and Figure 8 , wherein the needle assembly 230 is located at the third predetermined position relative to the ejection assembly 111). It should be understood that the third predetermined position is the position of the needle assembly 230 relative to the ejection assembly 111. At this time, the specific position of the ejection assembly 111 is not limited to the first predetermined position. The ejection assembly 111 can also be located beyond the first predetermined position in the direction toward the first end 101a, or at any position between the first predetermined position and the fifth predetermined position.

[0143] Please refer to Figure 3 and Figure 5 Preferably, the ejection assembly 111 includes a third limiting portion 141; the third limiting portion 141 is used to limit the movement of the needle assembly 230 relative to the ejection assembly 111 toward the second end 101b to no more than a third predetermined position. In one exemplary embodiment, the third limiting portion 141 includes a limiting platform 1412 facing the first end 101a, which can abut against the needle assembly 230 (specifically, a seventh limiting portion 2512 on the needle assembly 230, see the description of the needle assembly 230 below for details) to limit the movement of the needle assembly 230 relative to the ejection assembly 111 toward the second end 101b to no more than the third predetermined position.

[0144] Furthermore, the third limiting portion 141 is movably arranged along the radial direction of the base 101; the ejection assembly 111 includes a third potential energy portion 142; the third potential energy portion 142 is used to store potential energy during the movement of the needle assembly 230 relative to the ejection assembly 111 toward the first end 101a; after the needle assembly 230 moves relative to the ejection assembly 111 toward the first end 101a to exceed the third predetermined position, the third potential energy portion 142 releases the potential energy and drives the third limiting portion 141 to move along the radial direction of the base 101 to a fourth predetermined position (please refer to Figure 7 and Figure 8 , wherein the third limiting portion 141 is located at the fourth predetermined position); the third limiting portion 141 at the fourth predetermined position is used to abut against the needle assembly 230 to limit the movement of the needle assembly 230 relative to the ejection assembly 111 toward the second end 101b, so that the needle assembly 230 does not exceed the third predetermined position.

[0145] Optionally, the ejection assembly 111 is detachably connected to the needle assembly 230, and the third limiting portion 141 is used to release the needle from the needle withdrawal component 2111 (see the following description for details, refer to Figure 30 and Figure 31 ) is abutted and driven by the ejection assembly 111, thereby releasing the restriction on the movement of the needle assembly 230 and separating the needle assembly 230 from the ejection assembly 111. In some embodiments, the ejection assembly 111 and the needle assembly 230 are detachable, and the needle assembly 230 can be removed from the ejection assembly 111 after the implant is completed, making it easier to replace the implanter with a new needle assembly 230.

[0146] Preferably, the third limiting portion 141 includes a third slope 1411 that is inclined inwardly toward the second end 101b; during the movement of the needle assembly 230 relative to the ejection assembly 111 toward the first end 101a, the third limiting portion 141 gradually moves outward along the radial direction of the base 101 under the contact between the third slope 1411 and the needle assembly 230, and drives the third potential energy portion 142 to store potential energy. The third slope 1411 is also used to guide the movement of the needle assembly 230 toward the first end 101a. Please refer to Figure 5 、 Figure 7 and Figure 8 In one example, the third potential energy portion 142 includes a spring, one end of which is connected to the third limiting portion 141. When the needle assembly 230 moves relative to the ejection assembly 111 toward the first end 101a, the third limiting portion 141 is pushed outward (by the third slope 1411) Figure 5 and Figure 7After the needle assembly 230 moves relative to the ejection assembly 111 beyond the third predetermined position, the third limiting portion 141 is no longer squeezed by the needle assembly 230, and the spring of the third potential energy portion 142 releases the potential energy and pushes the third limiting portion 141 inward ( Figure 5 and Figure 7 The limiting platform 1412 of the third limiting portion 141 abuts against the seventh limiting portion 2512 on the needle assembly 230 (see Figure 11 ), limiting the needle assembly 230 from moving relative to the ejection assembly 111 toward the second end 101b to no more than a third predetermined position. Thus, the needle assembly 230 is confined in the ejection assembly 111 to prevent the needle assembly 230 from escaping from the ejection assembly 111.

[0147] In some other embodiments, the third limiting portion 141 may not be provided with the third slope 1411. In contrast, the seventh limiting portion 2512 on the needle assembly 230 may be provided with a corresponding sixth slope 2513 (see FIG. Figure 11 ), the sixth slope 2513 is outwardly inclined toward the first end 101a, and when the needle assembly 230 moves relative to the ejection assembly 111, it can push the third limiter 141 outward by abutting against it. Preferably, the third slope 1411 and the sixth slope 2513 can be provided simultaneously to reduce pushing resistance.

[0148] Of course, in some other embodiments, the sterilization box assembly 210 may only house the sensor base assembly 220, while the needle assembly 230 is disposed within the ejection assembly 111. Furthermore, in some embodiments, the needle assembly 230 may be fixedly connected to the ejection assembly 111 or movably connected thereto. The needle assembly 230 is detachably connected to the sensor base assembly 220. During use, the needle assembly 230 moves with the ejection assembly 111 toward the first end 101a, is ejected upon pressing the pressing portion 102, and is subsequently removed along with the implanter 100.

[0149] Because the ejection assembly 111 is detachably connected to the sensor base assembly 220, and the needle assembly 230 is detachably connected to the sensor base assembly 220, the reliability of the connection is not high. Therefore, the ejection assembly 111 may be additionally provided with a fifth stopper 121 to further ensure the reliability of the connection between the needle assembly 230 and the sensor base assembly 220 after the needle assembly 230 and the sensor base assembly 220 are loaded into the implanter 100 (i.e., when the ejection assembly 111 is in the first predetermined position). On the other hand, when the pressing portion 102 is pressed and the ejection assembly 111 moves toward the second end 101b (including when the ejection assembly 111 is between the first predetermined position and the fifth predetermined position, or when the ejection assembly 111 is in the fifth predetermined position), the fifth stopper 121 needs to be able to release the stop on the sensor base assembly 220, so that the sensor base assembly 220 can be separated from the needle assembly 230 and the ejection assembly 111 after the ejection assembly 111 moves toward the second end 101b to the fifth predetermined position.

[0150] In order to realize the connection relationship between the ejection assembly 111 and the sensor base assembly 220 at different stages, it is optional to refer to Figure 4 、 Figure 8 and Figure 10 The ejection assembly 111 includes a fifth limiting portion 121. When the ejection assembly 111 is in the first predetermined position, the fifth limiting portion 121 is used to limit the movement of the sensor base assembly 220 relative to the ejection assembly 111 toward the second end 101b. During the movement of the ejection assembly 111 from the first predetermined position toward the second end 101b, the fifth limiting portion 121 releases the restriction on the sensor base assembly 220. The fifth limiting portion 121 is used to provide additional positioning of the sensor base assembly 220 when the ejection assembly 111 is in the first predetermined position, thereby ensuring that the sensor base assembly 220 does not fall out of the implanter 100 after the needle assembly 230 and the sensor base assembly 220 are loaded into the implanter 100.

[0151] Please refer to Figure 8In an alternative exemplary embodiment, the base 101 includes a fourth slope 1016 that is inwardly inclined toward the second end 101b; the fifth limiting portion 121 is movably arranged along the radial direction of the base 101; during the movement of the ejection assembly 111 toward the first end 101a, the fifth limiting portion 121 is restricted by the fourth slope 1016 and gradually moves inward along the radial direction of the base 101, and is used to engage with the sensor base assembly 220 (specifically, the base 222 of the sensor base assembly 220, see the description of the sensor base assembly 220 below) to restrict the sensor base assembly 220 from moving relative to the ejection assembly 111 toward the second end 101b; during the movement of the ejection assembly 111 toward the second end 101b, the fifth limiting portion 121 gradually moves outward along the radial direction of the base 101 to release the engagement with the sensor base assembly 220, thereby releasing the restriction on the sensor base assembly 220. Preferably, the fifth limiting portion 121 includes a fifth slope 1211 inclined outwardly toward the first end 101 a , and the fifth slope is configured to match and abut against the fourth slope.

[0152] Furthermore, the ejection assembly 111 includes a fourth potential energy portion 122; the fourth potential energy portion 122 is used to provide potential energy to the fifth limiting portion 121 during the movement of the ejection assembly 111 toward the second end 101b, so that the fifth limiting portion 121 gradually moves outward along the radial direction of the base 101. Figure 4 and Figure 6 In an alternative exemplary embodiment, the fourth potential energy portion 122 includes a spring, one end of which is connected to the fifth limiting portion 121. When the ejection assembly 111 moves toward the first end 101a, the fifth limiting portion 121 is pushed inward ( Figure 4 When the ejection assembly 111 moves toward the second end 101b, the spring of the fourth potential energy portion 122 releases potential energy, pushing the fifth limiting portion 121 to abut against the fourth slope 1016 (if the fourth slope 1016 is not provided, the inner wall of the base 101 is abutted). As the ejection assembly 111 moves toward the second end 101b, the fifth limiting portion 121 gradually moves outward ( Figure 4 The fifth limiting portion 121 releases the engagement with the base 222 of the sensor base assembly 220.

[0153] Please refer to Figures 11 to 16This embodiment provides a needle assembly 230, which includes a housing 251 and a needle body 263. The housing 251 is connected to the needle body 263. The housing 251 is used to connect to the ejection assembly 111 of the implanter. The housing 251 is also used to detachably connect to the sensor base assembly 220. This embodiment also provides a sensor base assembly 220, which includes a base 222 and an adhesive layer 223. The base 222 has a third end 222a and a fourth end 222b opposite to each other along its own axis. One side of the third end 222a of the base 222 is used to detachably cooperate with the housing 251 of the needle assembly 230. The adhesive layer 223 is provided on one side of the fourth end 222b of the base 222. The needle assembly 230 and the sensor base assembly 220 are assembled and connected by the detachable connection between the shell 251 and the base 222. After the needle assembly 230 and the sensor base assembly 220 are ejected to the predetermined implantation site under the drive of the ejection assembly 111, the sensor base assembly 220 is adhered to the predetermined implantation site through the adhesive layer 223. The needle assembly 230 and the sensor base assembly 220 are separated, and the needle assembly 230 can be removed.

[0154] In one exemplary embodiment, the housing 251 includes a seventh potential energy portion 252 and a first engaging portion 2521. The first engaging portion 2521 is configured to be detachably connected to the sensor base assembly 220 along the axial direction of the housing 251. Correspondingly, the base 222 of the sensor base assembly 220 includes a second engaging portion 2222, which is detachably connected to the first engaging portion 2521 along the axial direction of the housing 251. When the first engaging portion 2521 is assembled and connected to the sensor base assembly 220, the seventh potential energy portion 252 stores potential energy and provides potential energy to the first engaging portion 2521, thereby causing the first engaging portion 2521 to abut against the sensor base assembly 220 along the radial direction of the housing 251. The first engaging portion 2521 can be a recessed slot or a raised tooth. Correspondingly, the second engaging portion 2222 is compatible with the first engaging portion 2521 and can be a raised tooth or a recessed slot. It should be understood that the first engaging portion 2521 and the second engaging portion 2222 preferably extend axially along the housing 251, i.e., both the tooth and the slot extend axially along the housing 251, to facilitate separation of the needle assembly 230 from the sensor base assembly 220. The connection between the first engaging portion 2521 and the second engaging portion 2222 can be achieved through friction or an interference fit, facilitating separation.

[0155] In one embodiment, the seventh potential energy portion 252 is an elastic arm, which can be a part of the housing 251 and has a certain elasticity. The first engaging portion 2521 is provided at one end of the elastic arm facing the sensor base assembly 220. When the first engaging portion 2521 is engaged with the second engaging portion 2222, the elastic arm of the seventh potential energy portion 252 stores potential energy. At the same time, the seventh potential energy portion 252 applies a force toward the outside ( Figure 12 The force (in the middle is toward both sides) causes the first engaging portion 2521 and the second engaging portion 2222 to abut against each other in the radial direction to generate friction, and the needle assembly 230 and the sensor base assembly 220 are assembled and connected. When the needle assembly 230 and the sensor base assembly 220 are subjected to an axial force moving away from each other, the needle assembly 230 and the sensor base assembly 220 overcome the friction and move away from each other until they are separated. The elastic arm releases potential energy and springs open, moving outward ( Figure 13 Expanding towards both sides).

[0156] In some embodiments, the needle 263 may be fixedly disposed in the housing 251 and move along with the housing 251. Preferably, in other embodiments, the needle 263 is movably connected to the housing 251 along the axial direction of the housing 251.

[0157] Please refer to Figure 12 Preferably, the needle assembly further includes a needle sleeve 253 and a sixth potential energy portion 262, and the two ends of the sixth potential energy portion 262 are fixedly connected to the needle sleeve 253 and the needle body 263, respectively; when the shell 251 is assembled and connected to the sensor base assembly 220, the sixth potential energy portion 262 stores potential energy, and the needle body 263 extends relative to the needle sleeve 253 along the axial direction of the shell 251; after the shell 251 is separated from the sensor base assembly 220, the sixth potential energy portion 262 releases potential energy, and the needle body 263 is gradually retracted into the needle sleeve 253 along the axial direction of the shell 251 to avoid accidental puncture.

[0158] like Figure 13As shown, in an optional exemplary embodiment, the needle body 263 is movably connected to the housing 251 along the axial direction of the housing 251, and the needle sleeve 253 is fixedly connected to the housing 251. When the housing 251 is assembled and connected to the sensor base assembly 220, the sixth potential energy portion 262 stores potential energy, and the needle body 263 extends out of the needle sleeve 253 along the axial direction of the housing 251; the sixth potential energy portion 262 stores potential energy; when the housing 251 is separated from the sensor base assembly 220, the sixth potential energy portion 262 releases potential energy, driving the needle body 263 to be retracted into the needle sleeve 253. In this exemplary embodiment, the needle sleeve 253 is fixed relative to the housing 251. When the housing 251 is separated from the sensor base assembly 220, the sixth potential energy portion 262 drives the needle body 263 to retract ( Figure 13 (moves upward in the middle), thereby causing the needle body 263 to be received in the needle sleeve 263.

[0159] like Figure 12 As shown, in another optional exemplary embodiment, the needle body 263 is fixedly connected to the shell 251, and the needle sleeve 253 is movably connected to the shell 251 along the axial direction of the shell 251; when the shell 251 is assembled and connected to the sensor base assembly 220, the sixth potential energy portion 262 stores potential energy, and the position of the needle sleeve 253 is restricted by the shell 251, so that the needle body 263 extends relative to the needle sleeve 253; when the shell 251 is separated from the sensor base assembly 220, the shell 251 releases the restriction on the needle sleeve 253, the sixth potential energy portion 262 releases the potential energy, and the needle sleeve 253 is gradually driven to the outside of the needle body 263 along the axial direction of the shell 251, that is, the needle sleeve 253 is driven to move and be sleeved outside the needle body 263. In this example, the needle body 263 is fixed relative to the housing 251. When the housing 251 is separated from the sensor base assembly 220, the sixth potential energy portion 262 drives the needle sleeve 253 to pop out ( Figure 12 (moves downward in the middle), thereby causing the needle body 263 to be received in the needle sleeve 263.

[0160] Furthermore, the shell 251 has a sixth limiting portion 2523; when the shell 251 is assembled and connected to the sensor base assembly 220, the sixth limiting portion 2523 is used to abut against the needle body 263 or the needle sleeve 253 (according to different embodiments, abut against one of the movable ones of the needle body 263 and the needle sleeve 253), so that the sixth potential energy portion 262 stores potential energy to limit the axial position of the needle body 263 or the needle sleeve 253 relative to the shell 251; when the shell 251 is separated from the sensor base assembly 220, the sixth limiting portion 2523 releases the abutment against the needle body 263 or the needle sleeve 253, so that the sixth potential energy portion 262 releases the potential energy to release the restriction on the position of the needle body 263 or the needle sleeve 253. The sixth limiting portion 2523 can be an inward protruding structure arranged on the elastic arm of the seventh potential energy portion 252. When the needle assembly 230 and the sensor base assembly 220 are assembled and connected, the first engaging portion 2521 and the second engaging portion 2222 engage with each other, and the elastic arm of the seventh potential energy portion 252 is constrained inward, so that the sixth limiting portion 2523 abuts against the needle body 263 or the needle sleeve 253.

[0161] In the example where the needle sleeve 253 is fixed and the needle body 263 is movable, the sixth limiting portion 2523 limits the needle body 263 from moving away from the sensor base assembly 220 ( Figure 12 When the needle assembly 230 is separated from the sensor base assembly 220, the first engaging portion 2521 and the second engaging portion 2222 are separated from each other, the seventh potential energy portion 252 releases potential energy, the elastic arm expands outward, the sixth limiting portion 2523 releases the abutment against the needle body 263, and the sixth potential energy portion 262 releases potential energy, driving the needle body 263 toward Figure 13 The needle 263 is quickly moved upward in the needle sleeve 253, so that the needle 263 is quickly withdrawn from the predetermined implantation site into the needle sleeve 253 to avoid accidental puncture. It is understood that the withdrawal of the needle 263 in this example can be automatic, that is, when the housing 251 is separated from the sensor base assembly 220, the needle 263 automatically withdraws. Of course, this example can also be achieved by the operator lifting the implanter 100.

[0162] In the example where the needle body 263 is fixed and the needle sleeve 253 is movable, the sixth limiting portion 2523 limits the needle sleeve 253 from moving to the Figure 12 When the needle assembly 230 is separated from the sensor base assembly 220, the first engaging portion 2521 and the second engaging portion 2222 are separated from each other, the seventh potential energy portion 252 releases potential energy, the elastic arm expands outward, the sixth limiting portion 2523 releases the abutment against the needle sleeve 253, and the sixth potential energy portion 262 releases potential energy, driving the needle sleeve 253 toward Figure 12The needle guard 253 is ejected from the bottom of the housing 251 so that the needle body 263 is sheathed outside the needle body 263 to avoid accidental puncture. It is understandable that the ejection of the needle guard 253 in this example is semi-automatic. That is, when the housing 251 is just separated from the sensor base assembly 220, the lower end of the needle guard 253 is blocked by the sensor base assembly 220 and the human body. Therefore, the needle guard 253 cannot be immediately sheathed outside the needle body 263. Instead, the operator needs to lift the implanter 100 to allow the needle body 263 to exit the human body. A certain space is created below the needle assembly 230 so that the needle body 263 can be ejected and sheathed outside the needle body 263.

[0163] Optionally, the needle body 263 includes a steel needle for piercing the implantation site, and a needle at the end of the steel needle ( Figure 13 The needle seat 261 is located in the upper middle portion of the needle assembly 230, and the steel needle is fixedly connected to the needle seat 261. The sixth potential energy portion 262 can be a spring, one end of which is connected to the needle seat 261 and the other end is connected to the needle sleeve 253. The purpose of the sixth potential energy portion 262 is to drive the needle body 263 to be retracted into the needle sleeve 253 when the needle assembly 230 is separated from the sensor base assembly 220. The needle assembly 230 of the present invention can be designed to automatically retract the needle body after the needle body has implanted the sensor portion into the predetermined location, or it can be designed to retract synchronously with the removal of the implanter.

[0164] Please refer to Figure 11 Preferably, the housing 251 includes a seventh limiting portion 2512, and the seventh limiting portion 2512 is used to abut against the third limiting portion 141 of the ejection assembly 111 (see Figure 5 ) to limit the movement of the housing 251 relative to the ejection assembly 111 toward the second end 101b to no more than a third predetermined position. When the needle assembly 230 is assembled and connected to the sensor base assembly 220, the radial dimension of the seventh limiting portion 2512 is smaller than the radial dimension of the seventh potential energy portion 252. Therefore, it can abut against the third limiting portion 141 of the ejection assembly 111, thereby preventing the housing 251 from dislodging from the ejection assembly 111 when the needle body 263 penetrates the implantation site. Preferably, the seventh limiting portion 2512 includes a sixth slope 2513, which is outwardly inclined toward the first end 101a. Furthermore, the needle assembly 230 is detachably connected to the ejection assembly 111. When the seventh limiting portion 2512 is released from the abutment against the third limiting portion 141 (such as through the abutment between the needle withdrawal component 2111 and the third limiting portion 141), the restriction on the movement of the shell 251 is released, and the needle assembly 230 is separated from the ejection assembly 111.

[0165] Please refer to Figure 5 、 Figure 14 and Figure 15Preferably, the ejection assembly 111 further includes a fifth potential energy portion 143; when the ejection assembly 111 is assembled and connected to the sensor base assembly 220, the fifth potential energy portion 143 stores potential energy; when the ejection assembly 111 and the sensor base assembly 220 are separated, the fifth potential energy portion 143 releases potential energy, driving the sensor base assembly 220 to move in a direction away from the ejection assembly 111. The fifth potential energy portion 143 may be a spring element; when the needle assembly 230 and the sensor base assembly 220 are assembled together on the ejection assembly 111, the spring element of the fifth potential energy portion 143 is squeezed and stores potential energy; when the sensor base assembly 220 and the needle assembly 230 are separated, the spring element of the fifth potential energy portion 143 releases potential energy, pushing the sensor base assembly 220 and the needle assembly 230 away from each other, thereby facilitating separation of the two. Specifically, after the sensor base assembly 220 and needle assembly 230 are ejected by the ejection assembly 111, the sensor base assembly 220 is attached to the predetermined implantation site via the adhesive layer 223. At this point, the implanter 100 is pulled away from the predetermined implantation site, and the potential energy stored in the fifth potential energy portion 143 helps separate the sensor base assembly 220 from the needle assembly 230. It is understood that the potential energy stored in the fifth potential energy portion 143 should be less than the friction force generated by the seventh potential energy portion 252 via the first engaging portion 2521 and the second engaging portion 2222, so that the sensor base assembly 220 and the needle assembly 230 are in a stable state when assembled and connected. In some embodiments, after the implanter 100 ejects the needle assembly 230 and the sensor base assembly 220 toward the predetermined implantation site and separates the needle assembly 230 from the sensor base assembly 220, the needle assembly 230 is retained in the implanter 100. Thereafter, the needle assembly 230 can be unloaded from the implanter 100 by certain measures and preferably placed into the sterilization box assembly 210 .

[0166] Please refer to Figures 28 to 32Preferably, the sterilization box assembly 210 includes a needle withdrawal component 2111, and the needle withdrawal component 2111 is used to abut against the third limiting portion 141 of the implanter 100. The third limiting portion 141 is used to release the restriction on the movement of the needle assembly 230 toward the second end 101b under the abutment drive of the needle withdrawal component 2111, so as to separate the needle assembly 230 from the implanter 100. Furthermore, in some embodiments, a second accommodating space is also formed inside the sterilization box shell 211. The second accommodating space can be arranged on the opposite side of the first accommodating space along the axial direction of the sterilization box shell 211. Accordingly, the needle withdrawal component 2111 is arranged on the opposite side of the sterilization box shell 211 and the first accommodating space; after the needle withdrawal component 2111 abuts against the third limiting portion 141 of the implanter 100 and releases the restriction of the third limiting portion 141 on the movement of the needle assembly 230, the needle assembly 230 moves from the implanter 100 to the second accommodating space.

[0167] In an exemplary embodiment, the third limiting portion 141 can be used to support the needle assembly 230 and help separate the needle assembly 230 and the sensor base assembly 220, and can also be used to separate the needle assembly 230 and the implanter 100 later. Figure 29 , one end of the third limiting portion 141 ( Figure 29 The left end of the third limiting portion 141 is used to abut against the seventh limiting portion 2512 on the needle assembly 230 to limit the movement of the needle assembly 230; the third limiting portion 141 as a whole can be radially (ie, radially) along the base 101 Figure 29 The left end of the third limiting portion 141 has a bend extending along the axis of the base 101. The upper end of the bend forms a stop 1412, which abuts against the seventh limiting portion 2512 to prevent the needle assembly 230 from being removed from the ejection assembly 111. The right end of the bend is connected to the base 101 via the third potential energy portion 142. This configuration ensures that when the third limiting portion 141 is not subjected to external forces, the third potential energy portion 142 maintains the bend in an extended position, thereby blocking the needle assembly 230.

[0168] The other end of the third limiting portion 141 ( Figure 29 The right end of the ejection assembly 111 has a limiting surface 1413, which faces the inside of the ejection assembly 111 ( Figure 29 The needle withdrawal component 2111 can be set on the side opposite to the first accommodating space. Figure 32 In the illustrated example, the needle withdrawal component 2111 is located at the side of the sterilization box housing 211 away from the cover 212, that is, at the bottom of the sterilization box assembly 210. When in use, the sterilization box assembly 210 can be inverted so that the needle withdrawal component 2111 is raised upward.

[0169] Please refer to Figure 31and 32 When the implanter 100 is buckled toward the bottom of the sterilization box assembly 210, the needle withdrawal component 2111 pushes the third limiting portion 141 toward the outside of the ejection assembly 111 ( Figure 31 The right side of the sterilization box assembly 210 is moved so that the limiting platform 1412 of the third limiting portion 141 is released from the contact with the seventh limiting portion 2512, and the needle assembly 230 can be released from the ejection assembly 111 under the action of gravity and fall into the sterilization box assembly 210. Preferably, the sterilization box assembly 210 further includes a claw 2112, which is arranged at the bottom of the sterilization box assembly 210 and its position corresponds to the falling needle assembly 230. Figure 28 and Figure 32 As shown, when it is necessary to separate the needle assembly 230 and the implanter 100, the sterilization box assembly 210 is turned upside down, and the ejection assembly 111 is pulled by the needle withdrawal component 2111, so that the ejection assembly 111 removes the restriction on the needle assembly 230, and when the needle assembly 230 falls, it can fall into the claw 2112.

[0170] Preferably, the needle assembly 230 further includes an eighth potential energy portion 2522 (e.g. Figure 11-13 ); when the housing 251 is assembled and connected to the ejection assembly 111, the eighth potential energy portion 2522 stores potential energy; when the housing 251 is separated from the ejection assembly 111, the eighth potential energy portion 2522 releases the potential energy, driving the housing 251 to move axially along the ejection assembly 111, thereby separating the housing 251 from the ejection assembly 111. The eighth potential energy portion 2522 may be an elastic member, which is used to provide a reverse thrust to the needle assembly 230 when the needle assembly 230 is separated from the ejection assembly 111, thereby facilitating the removal of the needle assembly 230 from the ejection assembly 111 and facilitating the unloading of the needle assembly 230.

[0171] In the implantation system provided in this embodiment, the needle assembly 230 is assembled and connected with the sensor base assembly 220 for placement in the sterilization box assembly 210; the implanter 100 is used to load the needle assembly 230 and the sensor base assembly 220 placed in the sterilization box assembly 210 along the direction from the first end 101a toward the second end 101b, until the ejection assembly 111 moves toward the first end 101a to the first predetermined position; the needle assembly 230 is used to separate from the sensor base assembly 220 after the sensor base assembly 220 is fitted with the predetermined implantation site; the launcher assembly 300 is used to assemble and connect with the sensor base assembly 220 after the needle assembly 230 is separated from the sensor base assembly 220.

[0172] Please refer to Figures 17 to 24Optionally, one side of the third end 222a of the base 222 is further configured to detachably engage with the transmitter assembly 300. The sensor base assembly 220 further includes a sensing portion 221, which is configured to be implanted into a predetermined location along with the needle body 263 of the needle assembly 230. After the sensor base assembly 220 is connected to the transmitter assembly 300, the sensing portion 221 and the transmitter assembly 300 are electrically connected. The transmitter assembly 300 can obtain monitoring data through the sensing portion 221 and transmit the monitoring data to a corresponding device. Preferably, the transmitter assembly 300 includes an upper cover 301, a lower cover 302, a circuit board 310, and a battery 320. The circuit board 310 and the battery 320 are accommodated between the upper cover 301 and the lower cover 302, and the battery 320 provides power to the circuit board 310.

[0173] Preferably, the base 222 includes a third engaging portion 2221, which is configured to engage with the transmitter assembly 300. Furthermore, this embodiment also provides a transmitter assembly 300, which includes a fourth engaging portion 3021, which is configured to engage with the third engaging portion 2221 of the sensor base assembly 220. The third engaging portion 2221 and the fourth engaging portion 3021 can be configured as mutually matching snaps, hooks, or slots. After the sensor base assembly 220 is adhered to the predetermined implantation site via the adhesive layer 223 and the implanter 100 is removed, the transmitter assembly 300 can be snapped onto the sensor base assembly 220, so that the third engaging portion 2221 and the fourth engaging portion 3021 engage with each other, thereby reliably assembling and connecting the transmitter assembly 300 and the sensor base assembly 220.

[0174] Further preferably, the third engaging portion 2221 can be positioned on the circumference or inner side of the base 222. If the third engaging portion 2221 is positioned on the circumference of the base 222, the third engaging portion 2221 can be aligned with the fourth engaging portion 3021, and then the transmitter assembly 300 can be pressed downward to engage with the sensor base assembly 220. If the third engaging portion 2221 is positioned on the inner side of the base 222, the transmitter assembly 300 can be tilted at a certain angle, such as approximately 30 degrees, so that the bottom latch at one end is inserted into the slot of the sensor base assembly 220. Then, the other end of the tilted transmitter assembly 300 can be pressed to engage the third engaging portion 2221 with the fourth engaging portion 3021 in the slot of the sensor base assembly 220. Both embodiments facilitate reliable assembly and connection between the transmitter assembly 300 and the sensor base assembly 220. Furthermore, because the connection position in the second embodiment is located on the inner side of the base 222, the lever principle is utilized, making installation more labor-saving.

[0175] Preferably, the sensor base assembly 220 further includes a flexible conductive portion 242, which is electrically connected to the sensing portion 221 and configured to be detachably connected to the transmitter assembly 300. The flexible conductive portion 242 may be a conductive rubber strip. When the third engaging portion 2221 and the fourth engaging portion 3021 engage with each other, the conductive rubber strip is elastically pre-tightened against the sensing portion 221 and the circuit board 310 in the transmitter assembly 300, respectively, to achieve electrical connection.

[0176] Preferably, the transmitter assembly 300 and the sensor base assembly 220 also adopt a systematic waterproof design, please refer to Figures 25 to 27 In an exemplary embodiment, the sensor base assembly 220 further includes an elastic sealing body 240 , which may be a silicone body, for example.

[0177] Systematic waterproofing design includes but is not limited to the following measures:

[0178] S1) The upper cover 301 and the lower cover 302 are fully sealed on all sides by a process such as ultrasonic welding, rubber rings, or integrated injection molding.

[0179] S2) The circuit board 310 is disposed between the upper cover 301 and the lower cover 302 , and the inner hole periphery of the circuit board 310 and the lower cover 302 are completely sealed by adhesive bonding or integral injection molding.

[0180] S3) The upper surface of the elastic sealing body 240 and the periphery of the middle exposed area of ​​the circuit board 310 are squeezed and sealed against each other by elastic pre-compression.

[0181] S4) The elastic sealing body 240 completely covers the sensing part 221 except the flexible conductive part 242, and squeezes and seals each other through elastic pre-compression.

[0182] S5) A drainage groove is provided at the portion of the base 222 that contacts the bottom of the transmitter assembly 300 to further improve the waterproof sealing performance.

[0183] In summary, in the implanter, needle assembly, sensor base assembly, transmitter assembly, sterilization box assembly and implantation system provided by the present invention, the implanter includes: a base, a pressing part, an ejection assembly and a first potential energy part; the base has a first end and a second end opposite to each other in the axial direction, and the base includes a first limiting part; the ejection assembly is movably arranged along the axial direction of the base; the ejection assembly is used to connect with the needle assembly and to be detachably connected with the sensor base assembly; the first potential energy part stores potential energy during the movement of the ejection assembly toward the first end; after the ejection assembly moves toward the first end and exceeds the first predetermined position, it is restricted by the first limiting part, thereby moving the ejection assembly toward the second end; after the pressing part is pressed, the restriction of the ejection assembly by the first limiting part is released, and the first potential energy part releases the potential energy to drive the ejection assembly to move toward the second end, thereby driving the needle assembly and the sensor base assembly to move toward the second end.

[0184] With this configuration, when the push portion is pressed, the first potential energy portion releases its potential energy, driving the ejection assembly, which in turn moves the needle assembly and sensor base assembly, completing the implantation. Since the ejection assembly and sensor base assembly are detachable, the implanter and needle assembly can be removed after implantation. The implantation portion consists solely of the sensor base assembly, and the implanter, after removing the needle assembly, can be recycled for multiple uses, effectively reducing costs and minimizing environmental impact.

[0185] It should be noted that the above embodiments can be combined with each other. The above description is only a description of the preferred embodiments of the present invention and does not limit the scope of the present invention. Any changes and modifications made by ordinary technicians in the field of the present invention based on the above disclosure are within the scope of protection of the claims.
