Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to sensor implantation devices and sensor implantation systems. Background Technology

[0002] With the development of medical device technology, sensor implantation devices for continuous glucose monitoring have emerged. These devices can assist sensors to be worn on the patient's body surface to achieve long-term, continuous monitoring of the patient's blood glucose levels. When the levels are abnormal, a timely reminder can be issued through the supporting software system, which facilitates patient self-management or long-term monitoring by the hospital.

[0003] In related technologies, continuous glucose monitoring systems typically employ an implantation method, with the implantation tool often relying on spring energy storage to achieve rapid sensor insertion and guide needle withdrawal. These devices are usually complex in structure, have numerous components, and are costly to manufacture. Furthermore, since they are mostly single-use, they generate more medical waste, placing a significant burden on the environment. In addition, during spring release, the guide needle is prone to high-frequency vibration, which may enlarge the incision, increase bleeding, and exacerbate patient pain and discomfort.

[0004] However, the above-mentioned injection implantation devices still have the following problems in actual use: complex structure, high cost, many parts, inconvenient installation, and the needle body vibration during the implantation process can easily lead to wound enlargement, increased bleeding, and obvious pain, affecting the patient experience and safety of use. Summary of the Invention

[0005] Based on this, the purpose of this application is to provide a sensor implantation device and system that optimizes the internal transmission and needle withdrawal mechanism to solve the problems of complex structure, inconvenient operation, and wound enlargement and increased pain caused by needle vibration in the prior art.

The movable trigger bracket is disposed on the upper cover, the fixed frame is disposed inside the movable trigger bracket, the locking needle assembly is disposed inside the fixed frame, and the elastic element is disposed between the locking needle assembly and the fixed frame.

[0009] The transmitter module, connected and disposed below the needle assist module, includes: a housing, a sensor, and a guide needle;

[0010] The sensor includes a proximal end and a distal end, the proximal end being disposed within the housing, and the distal end being housed within the guide pin; the guide pin penetrates the housing, and the upper end of the guide pin is disposed within the locking pin assembly;

[0011] The bottom cover and the top cover are fitted together to form a closed space, which is used to accommodate the transmitter module and the needle assist module;

[0012] The upper cover is configured to trigger the movable trigger bracket when pressed, and drive the movable trigger bracket to retract axially inward, thereby releasing the guide pin;

[0013] The locking pin assembly is configured to lock the guide pin when the movable trigger bracket is not triggered, and to retract the guide pin into the upper cover under the drive of the elastic element after the movable trigger bracket is triggered.

[0014] In one embodiment, the elastic element includes a spring, and the elastic element is configured to:

[0015] When the movable trigger bracket is not triggered, the elastic element is in an energy storage state; after the movable trigger bracket is triggered, the elastic element releases its stored energy, driving the locking pin assembly to retract the guide pin into the upper cover.

[0016] In one embodiment, the locking pin assembly is provided with a snap-fit ​​structure, which cooperates with the limiting part provided on the fixing frame to lock the elastic element.

[0017] In one embodiment, the movable trigger bracket is provided with a protruding structure. During the process of the movable trigger bracket being triggered to retract, the protruding structure interacts with the limiting part, driving the buckle structure to release the locking of the elastic element. Subsequently, the elastic element drives the locking needle assembly to carry the guide needle back into the needle assist module.

[0018] In one embodiment, the guide pin is provided with a groove, and the distal end is inclinedly received within the groove.

[0019] In one embodiment, the transmitter module further includes:

[0020] A sterilization assembly is disposed below the housing and includes a sterilization chamber and a sealing plug. The sealing plug is used to seal the bottom of the sterilization chamber, and a desiccant is disposed inside the sterilization chamber.

[0021] The tip of the guide needle is positioned inside the sterilization chamber.

[0022] In one embodiment, a separation component is disposed within the bottom cover, the separation component being configured to:

[0023] When the bottom cover is rotated to separate it from the top cover, the separation assembly separates the sterilization assembly from the transmitter module, thereby exposing the guide needle.

[0024] In one embodiment, the transmitter module further includes:

[0025] A circuit board assembly, a battery assembly, a signal transmission assembly, and a connector are disposed within the housing. The circuit board assembly is electrically connected to the sensor and is used to process sensor signals. The battery assembly is used to provide power.

[0026] A skin-friendly adhesive tape is placed on the underside of the housing.

[0027] In one embodiment, the needle assist module further includes:

[0028] A magnetic element, which is mounted on a fixed frame;

[0029] The housing contains a magnetic sensitive element;

[0030] The magnetic element is configured such that when the transmitter module is connected to the needle assist module, the magnetic field generated by the magnetic element acts on the magnetic sensitive element to control the on / off state of the internal circuit of the transmitter module.

[0031] A sensor implantation system includes the aforementioned sensor implantation device.

[0032] The aforementioned sensor implantation device integrates the needle-assist module inside the top cover. Through the coordinated operation of a movable trigger bracket, a fixing frame, a locking needle assembly, and an elastic element, pressing the top cover drives the movable trigger bracket to retract and release the guide needle. Subsequently, the elastic element releases its elastic potential energy, and the locking needle assembly quickly and smoothly retracts the guide needle back into the needle-assist module. This structure not only simplifies the implantation and withdrawal process, reduces the number of parts, lowers manufacturing costs and waste generation, but also effectively avoids the high-frequency vibration of the guide needle caused by spring release in traditional devices. This results in smaller incision size, reduced bleeding risk and patient pain, and improved safety and user experience. Attached Figure Description

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0064] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0065] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0066] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

[0069] See Figures 1-3 One embodiment of this application provides a sensor implantation device including: an upper cover 100, a needle assist module 200, a transmitter module 300, and a bottom cover 400. Combined with... Figure 4 As shown, Figure 4 An exploded view of a needle assist module according to an embodiment of this application is shown. The needle assist module 200 is disposed within the upper cover 100. The needle assist module 200 includes: a movable trigger bracket 210, a fixed frame 220, a needle locking assembly 230, and an elastic element 240. The movable trigger bracket 210 is disposed on the upper cover 100, the fixed frame 220 is disposed within the movable trigger bracket 210, the needle locking assembly 230 is disposed within the fixed frame 220, and the elastic element 240 is disposed between the needle locking assembly 230 and the fixed frame 220. Figures 5-8 As shown, the transmitter module 300 is connected and disposed below the needle assist module 200, and includes: a housing 310, a sensor 320, and a guide pin 330. The sensor 320 includes a proximal end 321 and a distal end 322. The proximal end 321 is disposed within the housing 310, and the distal end 322 is housed within the guide pin 330. The guide pin 330 penetrates the housing 310, and its upper end 331 is disposed within the locking pin assembly 230. The upper cover 100 and the bottom cover 400 are mated to form a closed space, which is used to accommodate the transmitter module 300 and the needle assist module 200.

[0070] The upper cover 100 is configured to trigger the movable trigger bracket 210 when pressed, and drive the movable trigger bracket 210 to retract axially inward, thereby releasing the guide pin 330. The locking pin assembly 230 is configured to lock the guide pin 330 when the movable trigger bracket 210 is not triggered; and after the movable trigger bracket 210 is triggered, it carries the guide pin 330 back into the upper cover 100 under the drive of the elastic element 240.

[0071] This application constructs a highly integrated implantation device through the compact layout and coordinated operation of the upper cover 100, the needle assist module 200, the transmitter module 300, and the lower cover. This layout makes the external operating interface (surface of the upper cover 100) of the device extremely simple, while all complex mechanical movements are completed in a closed loop inside the device, providing users with a "one-click" intuitive operating experience. Specifically, the user's single pressing pressure is converted into a continuous mechanical action: first, pressing the upper cover 100 triggers the moving trigger bracket 210 to retract axially inward, stably implanting the sensor 320 and the guide needle 330 into the tissue; then, the internally stored elastic potential energy is released, driving the locking needle assembly 230 to withdraw along the axial direction at high speed with the guide needle 330, and the sensor 320 is implanted into the tissue. The entire "implantation-withdrawal" process is completed automatically in milliseconds, forming a seamless integrated operating experience.

[0072] This "one-click trigger, automatic needle withdrawal" mechanism fundamentally simplifies the implantation process of the sensor 320. Users do not need professional skills or complex preparations; they can complete the entire process from implantation to withdrawal simply by pressing the top cover 100, significantly lowering the barrier to entry and making it particularly beneficial for patients to operate independently or for rapid clinical deployment. More importantly, through precise mechanical coordination and energy control, the mechanism achieves rapid and smooth withdrawal of the guide needle 330, effectively avoiding needle tremors or path deviations common during traditional needle withdrawal. This controllable withdrawal trajectory not only reduces secondary damage to subcutaneous tissue but also lowers the risk of wound enlargement and bleeding, thereby improving implantation safety while enhancing patient comfort and acceptance.

[0073] See Figure 2 , Figure 9 and Figure 10 When not triggered, the movable trigger bracket 210 of this application is partially located inside and partially outside the upper cover 100. Upon triggering, the movable trigger bracket 210 retracts axially inward under the pressure of the upper cover 100, releasing the guide pin 330 for implantation. Then, the pre-compressed elastic element 240 releases its elastic potential energy, driving the locking pin assembly 230 to quickly and smoothly retract the guide pin 330 back into the upper cover 100, completing the implantation and withdrawal of the sensor 320. The layout of the movable trigger bracket 210 allows it to simultaneously perform the dual functions of internal transmission and external triggering. The portion exposed outside the upper cover 100 provides the user with a clear force application interface, while the portion hidden inside performs the transmission. This design ensures direct transmission of the triggering force, avoiding energy loss and lag that may occur through multiple connectors.

[0074] In one embodiment, the elastic element 240 includes a spring, and is configured such that: when the movable trigger bracket 210 is not triggered, the elastic element 240 is in an energy-storing state; and when the movable trigger bracket 210 is triggered, the elastic element 240 releases its stored energy, driving the locking pin assembly 230 to retract the guide pin 330 into the upper cover 100. See also... Figure 16 , Figure 16 This is a schematic diagram of the assembly of the retainer 220 and the locking needle assembly 230. Because the elastic element 240 is pre-compressed between the locking needle assembly 230 and the retainer 220, it cannot be observed from this perspective. The elastic element 240, as the energy storage and execution unit of the device, is pre-compressed during the assembly stage to store energy, ensuring it remains in a high potential energy state before triggering. This design allows the device to achieve rapid response without relying on an external power source, solely through precise mechanical control. The pre-compressed spring provides constant acceleration at the moment of release, enabling the guide needle 330 to reach peak speed in the initial stage of retraction and complete the entire retraction stroke with approximately uniform deceleration. Compared to traditional manual needle withdrawal, this retraction method significantly shortens the needle's residence time in the tissue.

[0075] The selection of spring parameters directly affects the performance of the device. Excessive elastic force can lead to excessively high instantaneous acceleration peaks, potentially causing mechanism vibration; while insufficient elastic force cannot ensure the complete retraction of the guide pin 330. Experimental verification has shown that the optimal pin retraction effect can be achieved when the spring pre-compression force is controlled between 4-10N. Since the pin retraction action is entirely driven by pre-stored elastic potential energy, its execution process is unaffected by the user's operating skills or the stability of the applied force. Each trigger ensures a consistent pin retraction speed and trajectory, achieving standardized operation results.

[0076] See Figures 11-13 The locking needle assembly 230 is equipped with a latching structure 231, which cooperates with the limiting part 221 on the fixing frame 220 to lock the elastic element 240. This latching structure 231 and the limiting part 221 together constitute the locking and releasing mechanism of the entire needle assist module 200. Through their cooperation, the elastic element 240 can be reliably kept in a pre-compressed state when the device is not triggered, effectively preventing accidental release due to accidental contact or vibration, thereby ensuring the stability and safety of the device during storage and transportation.

[0077] Continue reading Figure 9-10In one embodiment of this application, the movable trigger bracket 210 is provided with a protruding structure 211. During the process of the movable trigger bracket 210 being triggered to retract, the protruding structure 211 interacts with the limiting part 221, driving the latching structure 231 to release the lock on the elastic element 240. Subsequently, the elastic element 240 drives the locking needle assembly 230 to carry the guide needle 330 back into the needle assist module 200. See also Figure 14 and Figure 15 , Figure 14 and Figure 15 The assembly relationship between the movable trigger bracket 210 and the fixed bracket 220 is shown. When the movable trigger bracket 210 is not triggered, the protrusion 211 on it engages with the limiting part 221 on the fixed bracket 220, forming a stable engagement state. This engagement state ensures that the movable trigger bracket 210 is reliably positioned in its initial position, and at the same time provides accurate guidance for the interaction between the protrusion 211 and the limiting part 221 during subsequent triggering.

[0078] During the triggering process of the movable trigger bracket 210, the protruding structure 211, acting as the driving element, moves along the following trajectory: When the movable trigger bracket 210 is pressed and retracts axially inward, the protruding structure 211 moves accordingly and begins to move upward along the guide surface of the limiting portion 221 on the fixed frame 220. This upward displacement converts the horizontal retraction motion of the bracket into a vertical force. Immediately afterwards, the upwardly moving protruding structure 211 directly contacts and acts on the latching structure 231 (which is also disposed within the limiting portion 221). At this moment, the protruding structure 211 applies a sufficiently large force to the latching structure 231, forcing the latching structure 231 to undergo instantaneous and irreversible plastic deformation, which permanently disengages the latching structure 231 from its locking engagement with the upper limiting portion 221 of the fixed frame 220. Once the latching structure 231 is released from locking due to plastic deformation, its constraint on the elastic element 240 is instantly released. The elastic potential energy previously pre-compressed and stored in the elastic element 240 is released in a very short time, and converted into kinetic energy to drive the locking needle assembly 230 and its guided needle 330 to retract at high speed and smoothly. The entire action is completed in one go, from mechanical triggering to energy release, ensuring the speed and accuracy of the needle withdrawal process, thereby minimizing tissue damage and patient pain.

[0079] See Figure 17In one embodiment, the guide pin 330 is provided with a groove 332, and the distal end 322 is inclinedly accommodated within the groove 332. This groove 332 provides crucial space for the fixation and protection of the sensor 320. The distal end 322 of the sensor 320 is embedded in the groove 332 at an angle, allowing the slender sensor 320 to integrate seamlessly with the robust guide pin 330. This arrangement not only provides comprehensive mechanical protection for the sensor 320 before implantation, preventing damage from accidental impacts or compression, but also ensures that the sensor 320 can enter the subcutaneous tissue along the trajectory set by the guide pin 330 at the moment of implantation, effectively preventing bending or displacement that may occur during the implantation process. Furthermore, when the guide pin 330 is rapidly retracted by the locking pin assembly 230, the contact surface between the distal end 322 of the sensor 320 and the inner wall of the groove 332, as well as its tilt angle, are designed to achieve smooth separation with minimal resistance. This smooth separation characteristic avoids disturbance to the implanted sensor 320, ensuring its accurate implantation position, and also reduces the possibility of tissue traction due to poor separation. This integrated design, housing the sensor 320 within the guide pin 330 groove 332, optimizes the overall structure of the implantation device. It eliminates the need for additional fixation components, simplifies the assembly process, and makes the entire transmitter module 300 more compact and reliable.

[0080] Based on some embodiments of this application, please continue to refer to... Figure 7 The transmitter module 300 also includes: a sterilization component 340, disposed below the housing 310, including a sterilization chamber 341 and a sealing plug 342, the sealing plug 342 being used to seal the bottom of the sterilization chamber 341, and a desiccant 343 being disposed inside the sterilization chamber 341; the tip 333 of the guide needle 330 is disposed inside the sterilization chamber 341.

[0081] The sterilization assembly 340 is designed to provide an independent protective environment for the tip 333 of the guide needle 330. The sterilization chamber 341 itself undergoes rigorous sterilization after assembly (the sterilization assembly 340 is then subjected to overall irradiation sterilization), and its internal space is completely isolated from the outside environment, ensuring that the tip 333 of the guide needle 330 remains sterile from production to clinical use. This built-in sterile barrier design reduces reliance on additional independent sterile packaging, simplifies clinical procedures, and minimizes the risk of secondary contamination during storage and unpacking. Simultaneously, the sealing plug 342 forms an airtight seal with the bottom of the sterilization chamber 341 through an interference fit or elastic snap, effectively blocking moisture, microorganisms, and other contaminants from the outside air. This seal not only ensures the sterility of the tip 333 of the guide needle 330 but also creates a dry environment for the built-in desiccant 343 to function, together forming a stable and controlled microenvironment. Desiccant 343 actively absorbs moisture that may remain during the packaging process or seep in through the packaging material, maintaining the humidity inside the chamber at an extremely low level. This is crucial for protecting the tip 333 of the guide needle 330 from oxidation and corrosion, maintaining its surface lubrication properties, and preventing the growth of microorganisms that may arise from moisture condensation, further enhancing aseptic protection and ensuring a smooth and safe puncture process.

[0082] See Figure 18 In one embodiment, a separation component 410 is provided within the bottom cover 400. This separation component 410 is configured to separate the sterilization component 340 from the transmitter module 300 when the bottom cover 400 is rotated to separate it from the top cover 100, thereby exposing the guide needle 330. The design of the separation component 410 combines the pre-use preparation process with the removal process of the sterilization chamber 341. When the user rotates the bottom cover 400 to separate it from the top cover 100, this routine operation simultaneously drives the separation component 410 to start working. This component, through a specific snap-fit ​​or cam structure, converts the rotational torque into a separation force acting on the sterilization component 340, thereby automatically exposing the tip 333 of the guide needle 330 while opening the packaging, saving the user the additional step of manually removing the sterilization chamber 341. The user does not need to find a separate removal point for the sterilization chamber 341, nor does he / she need to worry about the risk of contamination due to unfamiliarity with the operation.

[0083] Furthermore, those skilled in the art will understand that the specific implementation of the separation component 410 is not limited to a snap-fit ​​or cam structure. Other equivalent mechanical structures or transmission methods can be employed while ensuring the same function is achieved. For example, the separation component 410 can be designed to push the sterilization chamber 341 apart through axial displacement generated by thread engagement, or to utilize the lever principle to convert the opening action into an ejection force. Even a shear-type connection structure with a preset break point can be used to achieve physical separation when a specific torque is reached. The core concept of these alternative solutions is to reliably convert the rotation or pulling action of the bottom cover 400 into the removal action of the sterilization chamber 341 through mechanical linkage.

[0084] Continue reading Figure 8 In one embodiment, the transmitter module 300 further includes a circuit board assembly 350, a battery assembly 360, a signal transmission assembly 370, and a connector 380 disposed within the housing 310. The circuit board assembly 350 is electrically connected to the sensor 320 and is used to process the sensor 320 signal; the battery assembly 360 supplies power to the circuit board assembly 350 and the sensor 320; the signal transmission assembly 370 is connected to the circuit board assembly 350 and is used for wireless data transmission; the connector 380 is used to fix the sensor 320.

[0085] The circuit board assembly 350, through its circuit design, can receive weak physiological signals from the sensor 320 in real time, amplify, filter, and digitize them to effectively extract physiological parameter information. The battery assembly 360 provides power to the entire device; its compact design achieves maximum energy density within a limited space, ensuring that the transmitter module 300 can operate continuously for monitoring periods of several days or even weeks. This long-lasting power supply eliminates the need for frequent device replacements, greatly improving ease of use and user experience, while ensuring the continuity and integrity of monitoring data. The signal transmission assembly 370 enables wireless and remote data transmission. By employing wireless communication technologies such as Bluetooth Low Energy, this assembly can stably transmit processed physiological data to smartphones, dedicated receivers, or cloud servers. This wireless transmission method not only eliminates the inconvenience of traditional wired connections but also makes real-time remote monitoring possible. The design of the connector 380 ensures the precise positioning and reliable connection of the sensor 320 in terms of mechanical structure. It provides a solid support for the slim sensor 320, preventing displacement or loosening during the implantation process or use. This reliable connection mechanism lays a solid physical foundation for the long-term stable operation of the entire device.

[0086] Combination Figure 5The transmitter module 300 also includes a skin-friendly adhesive tape 390, which is located below the housing 310. The skin-friendly adhesive tape 390 serves as the direct contact interface between the transmitter module 300 and human skin, and its primary function is to ensure stable fixation of the device. Through its unique adhesive layer, the tape firmly adheres the transmitter module 300 to the skin surface, effectively preventing the device from shifting or falling off due to daily activities, clothing friction, or skin stretching.

[0087] Continue reading Figure 16 The needle-aid module 200 also includes a magnetic element 250, which is mounted on the mounting bracket 220. A magnetic sensitive element is located within the housing 310. The magnetic element 250 is configured such that when the transmitter module 300 is connected to the needle-aid module 200, the magnetic field generated by the magnetic element 250 acts on the magnetic sensitive element, controlling the on / off state of the internal circuitry of the transmitter module 300. This magnetically controlled switch mechanism provides a contactless power management solution for the transmitter module 300. When the transmitter module 300 and the needle-aid module 200 are correctly assembled in the storage state, the magnetic field generated by the magnetic element 250 on the mounting bracket 220 triggers the magnetic sensitive element within the housing 310, keeping the circuitry of the transmitter module 300 in a safe disconnected state. This design ensures that the battery power is not accidentally consumed during storage and transportation.

[0088] Furthermore, when the user is ready to use the sensor 320 implantation device, as the needle insertion module 200 separates from the transmitter module 300, the magnetic coupling between them disappears. The magnetic sensing element detects the attenuation or disappearance of the magnetic field strength and automatically connects the internal circuit of the transmitter module 300. This process eliminates the need for the user to perform any additional power-on operation, simplifying the usage steps, reducing the risk of monitoring interruption due to forgetting to power on, and improving the ease of use and reliability of the product.

[0089] This application also provides a sensor 320 implantation system, including the aforementioned sensor 320 implantation device. This sensor 320 implantation system includes not only the implantation device itself, but also a data receiving terminal and a display device. After the sensor 320 is implanted in the human body, the collected physiological data is transmitted wirelessly to the associated data receiving terminal. Users can view their health indicators, such as trends in blood sugar levels, on the display device.

[0090] The sensor implantation device in this application is used as follows:

[0091] Before use, the device is in a fully encapsulated state. First, hold the main body of the device with one hand and the bottom cover 400 with the other, and separate the bottom cover 400 from the top cover 100 by rotating it. During the rotation of the bottom cover 400, the internal separation component 410 will move simultaneously, detaching the sterilization component 340 from the transmitter module 300. This continuous action not only removes the bottom cover 400, but also simultaneously opens the sterilization chamber 341, allowing the tip 333 of the guide needle 330 to be safely exposed from the sterile environment. At the same time, the internal moving trigger bracket 210 of the device will automatically enter the ready-to-trigger state.

[0092] After completing the preparation, align the front end of the device (i.e., the end where the guide needle 330 is located) with and firmly attach it to the patient's cleaned and disinfected skin implantation site. After ensuring that the device is completely in contact with the skin surface, press the top cover 100. The pressing action will drive the internal moving trigger bracket 210 to retract axially inward. This process first stably implants the guide needle 330 along with the sensor 320 into the subcutaneous tissue.

[0093] When the movable trigger bracket 210 retracts to the predetermined unlocking position inside, the protruding structure 211 on it interacts with the limiting part 221 of the fixing bracket 220, triggering the locking pin assembly 230 to unlock. At this time, the pre-compressed elastic element 240 instantly releases the stored elastic potential energy, driving the locking pin assembly 230 to carry the guide pin 330 back from the subcutaneous tissue at high speed and smoothly, and completely retract into the upper cover 100.

[0094] As the guide needle 330 retracts, the distal end 322 of the sensor 320 smoothly separates from the guide needle 330 and is precisely placed in the subcutaneous tissue to complete the implantation. Throughout the implantation process, the transmitter module 300 is firmly adhered to the skin surface with the help of the skin-friendly adhesive tape 390. Finally, the needle aid module 200, which has completed the needle withdrawal action, is separated from the transmitter module 300 fixed on the skin, completing the implantation.

[0095] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0096] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
