Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and specifically relates to a blood glucose sensor implanter. Background Technology

[0002] Diabetes is a common and prevalent disease among middle-aged and elderly patients. As a lifelong condition, there is currently no cure. Current treatment for diabetes primarily involves frequent monitoring of blood glucose levels and adjusting the dosage of hypoglycemic drugs and insulin accordingly. Most mainstream home-use portable blood glucose meters on the market use capillary blood sampling, requiring a single prick for each test. While these portable meters offer the advantage of low cost, the frequent pricking not only causes significant pain but is also inconvenient.

[0003] Patent document CN208677403U discloses a blood glucose sensor implanter, including a housing with one open end, a fixing member fixed inside the housing, and an implantation member disposed on the fixing member facing the opening of the housing. The implantation member includes a sensor for piercing the skin to detect blood glucose concentration, and an adhesive patch for adhering to the skin surface to prevent the sensor from falling off. The sensor is fixedly connected to the adhesive patch. The housing also contains a needle for assisting the sensor in piercing the user's skin, and a ejection device movably connected inside the housing and connected to the needle for controlling the needle to automatically withdraw after piercing the skin to a certain depth. This achieves the goal of leaving the blood glucose concentration sensor in the skin, thereby reducing the number of times the patient needs to prick the needle to collect blood for blood glucose concentration detection.

[0004] However, the aforementioned blood glucose sensor implants still have the following problems: (1) Risk of cross-contamination between disinfection and implantation. To ensure cleanliness during the implantation process, users need to disinfect their skin separately and wait for it to evaporate. However, in clinical practice, separate disinfection is prone to leakage, and often, when the disinfectant solution is implanted before it has completely evaporated, the unevaporated disinfectant solution carrying temporary bacteria on the skin surface may be introduced into the subcutaneous tissue through the needle, increasing the risk of local infection. In addition, the chemical components of the disinfectant may also contaminate the sensitive parts of the sensor probe, affecting the accuracy and stability of its monitoring.

[0005] (2) Inadequate prevention and control of puncture-related complications. At the moment of needle insertion and withdrawal, capillaries may be punctured, resulting in minor bleeding or subcutaneous hematoma. The dual-device lacks an immediate and effective physical hemostasis mechanism and relies only on subsequent application and pressure, which has a limited hemostatic effect. Subcutaneous hematoma or hematoma not only causes discomfort to the user, but may also temporarily affect the accuracy of blood glucose monitoring data due to changes in tissue fluid composition.

[0006] Therefore, there is an urgent need to design a blood glucose sensor implant to solve the above problems. Summary of the Invention

[0007] To address the issues of cross-contamination risks during disinfection and implantation, and insufficient prevention and control of puncture-related complications in existing implantation devices, this invention aims to provide a blood glucose sensor implanter, comprising a blood glucose sensor assembly, a transmitter, and an implantation mechanism. The transmitter is fitted onto the upper end of the blood glucose sensor assembly for skin disinfection. The implantation mechanism is inserted into the transmitter from top to bottom, engaging and communicating with the blood glucose sensor assembly. The implantation mechanism works in conjunction with the blood glucose sensor assembly to complete the pre- and post-implantation procedures of air blowing, pressure application, and implantation. This invention integrates five functions—disinfection, residual fluid blowing, puncture, micro-pressure hemostasis, and needle removal—into a single mechanical structure. Users only need a single pressure action to complete the entire sensor implantation process, eliminating the need for additional tools or step-by-step operations. This significantly reduces the operational threshold and the risk of human error, while simultaneously avoiding the risks of cross-contamination during disinfection and implantation, and the inadequate prevention and control of puncture-related complications.

[0008] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A glucose sensor implantable device includes a glucose sensor assembly and further includes: The transmitter, fitted onto the upper part of the blood glucose sensor assembly, is used for skin disinfection; The implantation mechanism is inserted into the transmitter from top to bottom, and is connected to and connected with the blood glucose sensor assembly. The implantation mechanism works in conjunction with the blood glucose sensor assembly to disinfect, press, and implant the blood glucose sensor assembly around the puncture point.

[0009] Preferably, the transmitter includes: The transmitter body has an internal partition, with the implantation mechanism located on the upper side of the partition and the blood glucose sensor located on the lower side of the partition. A flexible ring is located at the bottom edge of the transmitter body, and several spray bars are provided on the flexible ring to spray disinfectant from inside the flexible ring onto the skin.

[0010] Preferably, the implantation device includes: The I-shaped piston rod is used to inflate the blood glucose sensor assembly; The T-shaped connecting tube assembly is fitted onto the I-shaped piston rod at the upper end and set on the partition at the lower end. It is used in conjunction with the I-shaped piston rod to drive the blood glucose sensor to work and complete the implantation. The reset component is sleeved on the T-shaped connecting tube and located on the upper side of the partition plate, and is used to drive the T-shaped connecting tube to reset.

[0011] Preferably, the T-shaped connecting pipe assembly includes: The upper end of the T-shaped tube is connected to the I-shaped piston rod. The implantation needle is connected at the upper end to the body of the T-shaped tube and extends out of the body of the T-shaped tube at the lower end. It is used in conjunction with the blood glucose sensor assembly to complete the implantation.

[0012] Preferably, the reset component includes: Two fixing plates are symmetrically fitted onto the T-shaped tube from top to bottom. The upper fixing plate is fixedly fitted to the T-shaped tube, and the lower fixing plate is slidably fitted to the T-shaped tube. Two corrugated pipes are set between two fixed plates and located on both sides of the T-shaped pipe body. Both corrugated pipes are connected to the T-shaped pipe body. The elastic element is fitted onto the T-shaped tube and located between the two fixed plates.

[0013] Preferably, the blood glucose sensor assembly includes: The blood glucose sensor body is located on the lower side of the partition and is connected to the T-shaped tube. The probe on the blood glucose sensor body is sleeved inside the implantation needle. A waterproof sticker is placed on the underside of the blood glucose sensor.

[0014] Preferably, the blood glucose sensor assembly further includes: A soft hemostatic pad is placed on the underside of the blood glucose sensor body and is connected to the T-shaped tube for spraying air onto the skin; A soft protective deformation sleeve is placed at the lower end of the soft hemostatic pad and is fitted over the implantation needle to prevent disinfectant from contaminating the implantation needle.

[0015] Preferably, the soft hemostatic pad has a trumpet-shaped structure and multiple air jet holes at the lower end.

[0016] Preferably, the flexible protective deformation sleeve includes multiple flexible deformation plates that fit together, with the lower ends of the flexible deformation plates curving outwards.

[0017] The beneficial effects of this invention are: This invention discloses a blood glucose sensor implanter, and compared with the prior art, the improvement of this invention lies in: (1) The present invention integrates the transmitter with the flexible ring and spray bar, which solves the problems of traditional implantation devices that require the separate use of disinfectant cotton pads, are prone to leakage, and are cumbersome to operate. It realizes the integrated operation of "disinfection upon pressing". The disinfectant is sprayed directionally on the skin around the puncture point, evenly and without residue. It will not leak when not in use, which significantly improves the disinfection efficiency and hygiene. In addition, the blood glucose sensor body and the transmitter are connected by magnetic attraction, which solves the problems of untimely separation, jamming and additional unlocking operation required during the implantation process. It realizes automatic separation under the push force during implantation, smooth separation without interference, simple structure, reliable connection, and improves the implantation success rate and smooth operation.

[0018] (2) This invention solves the problem of residual alcohol on the skin surface after disinfection entering the subcutaneous tissue with the implanted needle, which can easily cause infection and interfere with the sensor detection signal by forming a secondary blowing structure composed of an I-shaped piston rod and a jet hole of a soft hemostatic pad. It achieves targeted blowing and forced evaporation of the central area of ​​the puncture point, thoroughly removes residual disinfectant, effectively reduces the risk of infection at the puncture point, and ensures the accuracy and stability of blood glucose monitoring data.

[0019] (3) By connecting the bellows in the repositioning assembly with the soft hemostatic pad and using the air jet hole to form a closed expansion cavity by sealing the skin in the later stage of implantation, the present invention solves the problems of subcutaneous bleeding, ecchymosis and strong pain in patients after needle removal of traditional implanters. It achieves controllable and continuous downward micro-pressure on the skin around the puncture point before and at the moment of needle removal, immediate physical hemostasis, significantly reducing subcutaneous bleeding and ecchymosis, improving patient comfort, and providing a more stable initial tissue environment for the probe.

[0020] (4) This invention solves the problem that disinfectant can easily seep into the sensor probe along the implantation needle before implantation, causing probe contamination or deactivation of active substances by setting a soft protective deformation sleeve composed of multiple soft deformation plates at the lower end of the soft hemostatic pad. It achieves full encapsulation and isolation between the probe and the implantation needle before implantation. During implantation, the deformation plate automatically and evenly unfolds without obstructing puncture. After implantation, it adheres to the bottom of the sensor to form secondary protection. The whole process is passive, energy-efficient, and highly reliable.

[0021] (5) By placing the waterproof patch and the soft hemostatic pad concentrically on the underside of the blood glucose sensor body, this invention solves the problems of poor fixation after sensor implantation and easy infection of the puncture point due to sweat or liquid infiltration. It achieves a dual sealing and fixing structure with the waterproof patch and skin adhesion and the soft hemostatic pad compression and adhesion. It has good stability for long-term wear, effectively reduces the risk of infection at the puncture point, and improves the service life of the sensor and the continuity of monitoring.

[0023] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings. Preferred embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of this application.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] Example: See attached document Figures 1-14The illustrated blood glucose sensor implanter includes a blood glucose sensor assembly 1, a transmitter 2, and an implantation mechanism 3. The transmitter 2 is sleeved on the upper end of the blood glucose sensor assembly 1, i.e., the blood glucose sensor assembly 1 is located inside the lower end of the transmitter 2. The implantation mechanism 3 is movably inserted into the transmitter 2 from the upper end of the transmitter 2 and is sleeved and connected to the blood glucose sensor assembly 1. It is used in conjunction with the blood glucose sensor assembly 1 to complete the disinfection, pressing, and implantation work around the puncture point before implantation.

[0026] During use, transmitter 2 can disinfect a certain area of ​​the skin to be punctured. The manually driven implantation mechanism 3 can drive the blood glucose sensor component 1 to further blow air onto the small part of the skin to be punctured, preventing residual disinfectant solution with skin bacteria from entering the skin with the puncture needle, which could lead to bacterial infection of the patient and affect the probe detection accuracy of the blood glucose sensor component 1. The blood glucose sensor component 1 can also protect the probe from contact with the disinfectant solution when the transmitter 2 is disinfected, thus avoiding affecting the use of the probe. At the same time, it works in conjunction with the implantation mechanism 3 to complete the probe implantation operation. At the same time, a downward micro-pressure is applied to the skin before the needle needs to be removed. At the moment of needle removal, controllable micro-pressure is applied to the skin around the puncture point to achieve immediate physical hemostasis, effectively preventing the formation of subcutaneous bleeding and bruising. This not only improves user comfort but also provides a more stable initial monitoring environment for the probe.

[0027] In the embodiments of this application, reference is made to the appendix. Figures 2-3 As shown, the transmitter 2 includes a transmitter body 201 and a flexible ring 202. The transmitter body 201 is a hollow cylindrical structure with a partition 2011 inside. A hole is provided at the center of the partition 2011 to facilitate communication between the upper and lower parts of the partition 2011. The implantation mechanism 3 and the blood glucose sensor assembly 1 are located on the upper and lower sides of the partition 2011 respectively and are interconnected. The flexible ring 202 is a hollow structure, preferably made of rubber or silicone, and is fixedly bonded to the bottom edge of the transmitter body 201. Several spray rods 2021 are provided on the flexible ring 202. The spray rods 2021 face the center of the transmitter body 201 and are obliquely upward to prevent the disinfectant from flowing out of the spray rods 2021 when not in use. The spray rods 2021 are used to spray the disinfectant inside the flexible ring 202 onto the skin, and the spray rods 2021 are also made of silicone or rubber.

[0028] When in use, applying downward pressure to the transmitter body 201 will squeeze the flexible ring 202, causing it to squeeze the disinfectant solution in the inner cavity out of the spray bar 2021, thereby disinfecting the skin around the puncture point surrounded by the transmitter body 201. The disinfectant solution can be alcohol. Multiple vent holes 2012 are provided on the outer periphery of the transmitter body 201 to assist in the evaporation of alcohol.

[0029] In the embodiments of this application, reference is made to the appendix. Figures 4-8 As shown, the implantation mechanism 3 includes an I-shaped piston rod 301, a T-shaped connecting tube assembly 302, and a reset assembly 303. The I-shaped piston rod 301 is used to inflate the sensor assembly 1, with its upper end being the pressing end and its lower end being the piston end. The upper end of the T-shaped connecting tube assembly 302 is sleeved on the lower end of the I-shaped piston rod 301, and the lower end of the T-shaped connecting tube assembly 302 is slidably mounted on the partition 2011. It can communicate with the blood glucose sensor assembly 1 through a hole in the partition 2011 to supply air to the blood glucose sensor assembly 1. At the same time, the T-shaped connecting tube assembly 302 works in conjunction with the I-shaped piston rod 301 to drive the blood glucose sensor assembly 1 to work and complete the implantation. The reset assembly 303 is fixedly sleeved on the T-shaped connecting tube assembly 302 and is located on the upper side of the partition 2011 to drive the T-shaped connecting tube assembly 302 to reset.

[0030] In use, first press the I-shaped piston rod 301, causing its lower end to move downward relative to the T-shaped connecting tube assembly 302. This squeezes the gas inside the T-shaped connecting tube assembly 302 into the blood glucose sensor assembly 1, allowing the blood glucose sensor assembly 1 to blow air onto the skin near the puncture point before implantation. This further promotes the evaporation of alcohol in the skin in that area, preventing unevaporated alcohol from entering the patient's body with the implantation needle and thus carrying bacteria or viruses from the skin surface into the subcutaneous tissue, leading to infection at the puncture point and affecting probe detection results. When the I-shaped piston rod 301 is attached to the T-shaped connecting tube assembly 302 and continues to move downward, the reset assembly 303 is squeezed to drive the probe of the blood glucose sensor assembly 1 into the patient's subcutaneous tissue. The blood glucose sensor assembly 1 also applies micro-pressure to the puncture point, achieving immediate physical hemostasis and effectively preventing subcutaneous bleeding and bruising. This improves user comfort and provides a more stable initial monitoring environment for the probe. Then, the downward pressure is released, and the reset assembly 303 drives the T-shaped connecting tube assembly 302 to move upward instantly, thereby implanting the blood glucose sensor assembly 1.

[0031] For details, please refer to the appendix. Figure 6 As shown, the T-shaped connecting tube assembly 302 includes a T-shaped tube body 3021 and an implantation needle 3022. The upper end of the T-shaped tube body 3021 is sleeved with an I-shaped piston rod 301, which can perform piston movement inside the T-shaped tube body 3021. The lower end of the T-shaped tube body 3021 is slidably mounted on a partition 2011 and communicates with the blood glucose sensor assembly 1 through a hole in the partition 2011, meaning the T-shaped tube body 3021 can movably pass through the partition 2011. The implantation needle 3022 is a steel needle with a beveled end, used to pierce the patient's skin to implant the probe of the blood glucose sensor assembly 1 subcutaneously. The upper end of the implantation needle 3022 is connected to the lower end inside the T-shaped tube body 3021, and the lower end protrudes outside the T-shaped tube body 3021 and extends into the blood glucose sensor assembly 1, wrapping around the probe of the blood glucose sensor assembly 1, and working with the blood glucose sensor assembly 1 to complete the implantation.

[0032] When the T-shaped tube 3021 moves downward relative to the transmitter body 201, it will drive the implantation needle 3022 to move downward synchronously. The implantation needle 3022 is fixed in the inner cavity of the T-shaped tube 3021 by the crossbar, which will not affect the gas outflow from the inside of the T-shaped tube 3021.

[0033] For details, please refer to the appendix. Figure 7 As shown, the reset assembly 303 includes two fixing plates 3031, two bellows 3032, and an elastic element 3033. The two fixing plates 3031 are circular with concentric through holes at their centers. They are symmetrically fitted onto the T-shaped tube 3021 through these through holes. The upper fixing plate 3031 is fixedly fitted to the T-shaped tube 3021, while the lower fixing plate 3031 is slidably fitted to the T-shaped tube 3021. That is, the T-shaped tube 3021 can be slidably fitted relative to the lower fixing plate 3032. 031 moves down; two corrugated pipes 3032 are set between two fixed plates 3031 and located on both sides of the T-shaped tube body 3021. Both corrugated pipes 3032 are connected to the T-shaped tube body 3021, and the upper and lower ends of the corrugated pipes 3032 are bonded to the two fixed plates 3031; the elastic element 3033 can be a spring or a spring sheet, which is sleeved on the tube body of the T-shaped tube body 3021 and located between the two fixed plates 3031. The two ends of the elastic element 3033 are fixedly bonded to the two fixed plates 3031.

[0034] When the T-shaped tube 3021 moves downward relative to the transmitter body 201, it causes the upper fixing plate 3031 to squeeze the elastic element 3033, and at the same time squeeze the two bellows 3032, forcing the gas in the bellows 3032 into the T-shaped tube 3021, and then into the blood glucose sensor assembly 1 from the T-shaped tube 3021; ​​when the force applied to the T-shaped connecting tube assembly 302 disappears, the elastic element 3033 causes the T-shaped tube 3021 to move upward and reset, and at the same time causes the two bellows 3032 to return to their initial positions.

[0035] In the embodiments of this application, reference is made to the appendix. Figures 9-14As shown, the blood glucose sensor assembly 1 includes a blood glucose sensor body 101, a waterproof patch 102, a soft hemostatic pad 103, and a soft protective deformation sleeve 104. The blood glucose sensor body 101 is a prior art device, which includes a sensor and a transmitter. The sensor is a miniature probe used to pierce the patient's subcutaneous tissue. The sensor contains bioactive substances such as glucose oxidase, which can specifically react with glucose in the interstitial fluid to generate an electrical signal, thereby converting the glucose concentration into a detectable signal. The transmitter is fixed to the skin surface or integrated with the sensor, and is responsible for receiving the signal collected by the sensor and continuously transmitting blood glucose data to the receiving terminal via wireless technology (such as Bluetooth). This application does not make any improvements to the structure and operating principle of the blood glucose sensor body 101. The blood glucose sensor body 101 is magnetically attached to the underside of the partition 2011 and is connected to the T-shaped tube 3021. The probe on the blood glucose sensor body 101 is sleeved inside the implantation needle 3022.

[0036] For details, please refer to the appendix. Figure 6 As shown, a magnetic sheet 1 is provided on the upper end of the transmitter of the blood glucose sensor body 101, and a magnetic sheet 2 is provided on the lower side of the partition 2011. The magnetic sheet 1 and the magnetic sheet 2 are opposite magnets. Through the mutual attraction of the magnetic sheet 1 and the magnetic sheet 2, the blood glucose sensor body 101 is attracted to the lower side of the partition 2011, and the blood glucose sensor body 101 extends through the through hole on the partition 2011 to the inner cavity of the T-shaped tube 3021, realizing the communication with the T-shaped tube 3021. At this time, the probe on the blood glucose sensor body 101 is sleeved in the implantation needle 3022.

[0037] The waterproof sticker 102 is fixedly attached to the lower side of the transmitter of the blood glucose sensor body 101, and the lower end of the waterproof sticker 102 is provided with an adhesive layer to facilitate adhesion to the patient's skin.

[0038] The soft hemostatic pad 103 has a trumpet-shaped structure with a triangular vertical cross-section and is made of a deformable material, such as silicone or rubber. The soft hemostatic pad 103 has a double-layer structure with an internal cavity and an air jet hole 1031 at the bottom. The soft hemostatic pad 103 is positioned at the center of the blood glucose sensor body 101 and is concentrically positioned with the waterproof patch 102. It is connected to the T-shaped tube 3021 through the blood glucose sensor body 101. Airflow enters the soft hemostatic pad 103 from the T-shaped tube 302 and is then ejected from the air jet hole 1031 to spray air onto the skin, ensuring no disinfectant residue remains at the puncture site.

[0039] The flexible protective deformation sleeve 104 is set at the lower end of the flexible hemostatic pad 103 and is fitted over the implantation needle 3022 to prevent disinfectant from contaminating the implantation needle 3022. When the blood glucose sensor body 101 is implanted, the flexible protective deformation sleeve 104 opens and fits tightly against the lower end of the blood glucose sensor body 101.

[0040] Furthermore, the flexible protective deformation sleeve 104 is composed of multiple flexible deformation plates 1041 that fit tightly together. The upper end of the flexible deformation plate 1041 is bonded to the flexible hemostatic pad 103, and the lower end is raised outward, so that under downward pressure, each flexible deformation plate 1041 can unfold in a different direction and finally fit tightly with the lower end of the flexible hemostatic pad 103.

[0041] The preferred embodiment of the blood glucose sensor implanter operates as follows: First, the implanter is placed on the patient's arm skin, so that the lower end of the transmitter body 201 contacts the patient's skin. Then, a downward pressure is manually applied to the transmitter body 201, which will squeeze the flexible ring 202 on the skin, squeezing the disinfectant solution in its inner cavity out of the spray rod 2021, thereby disinfecting the skin around the puncture point surrounded by the transmitter body 201. The multiple vent holes 2012 on the outer periphery of the transmitter body 201 can be used to assist in the evaporation of alcohol.

[0042] Wait approximately one minute and keep the device stationary on the skin surface. Press the I-shaped piston rod 301 directly, causing its lower end to move downward relative to the T-shaped connecting tube assembly 302. This forces the gas in the inner cavity of the T-shaped connecting tube assembly 302 into the inner cavity of the soft hemostatic pad 103. The gas is then ejected from the jet nozzle 1031 at its lower end to spray the small area of ​​skin around the puncture point. This prevents residual disinfectant solution from remaining on the skin around the puncture point, further addressing the issue of unevaporated alcohol entering the patient's body with the implanted needle. This would carry bacteria or viruses from the skin surface into the subcutaneous tissue, leading to puncture point infection and affecting probe detection results.

[0043] When the I-shaped piston rod 301 is in contact with the T-shaped tube 3021 and continues to move downward, the I-shaped piston rod 301 and the T-shaped tube 3021 form a whole and move downward relative to the transmitter body 201, causing the upper fixing plate 3031 to move downward synchronously and simultaneously compress the elastic element 3033 and the two bellows 3032. The T-shaped tube 3021 then moves downward relative to the lower fixing plate 3031 and the partition plate 2011. At this time, the lower fixing plate 3031... The implanted needle 3022 continues to move downwards, moving the blood glucose sensor body 101 away from the lower end of the partition 2011. At this point, the flexible protective deformation sleeve 104 first contacts the skin. As it continues to move downwards, it compresses multiple flexible deformation plates 1041, causing them to unfold in different directions without obstructing the continued insertion of the implanted needle 3022. As it continues to move downwards, the implanted needle 3022 pierces the patient's skin, and the multiple flexible deformation plates 1041 unfold simultaneously. When the soft hemostatic pad 103 is lowered along with the T-shaped tube 3021 and its bottom contacts the skin, the skin blocks the air vent 1031 at the bottom of the soft hemostatic pad 103. Because the gas entering the soft hemostatic pad 103 through the T-shaped tube 302 due to the compression of the two corrugated tubes 3032 cannot be discharged through the soft hemostatic pad 103, the continuously input gas will cause the soft hemostatic pad 103 to expand, putting downward pressure on the skin near the puncture point, avoiding bruising due to puncture, improving user comfort, and providing a more stable initial monitoring environment for the probe. At this time, the implantation needle 3022 has also been implanted into the patient's body with the probe of the blood glucose sensor body 101. The transmitter on the blood glucose sensor body 101 is attached to the patient's skin by the waterproof patch 102. The soft hemostatic pad 103 and the soft protective deformation sleeve 104 are squeezed and completely attached to the lower side of the transmitter on the blood glucose sensor body 101 and fixed with the waterproof patch 102.

[0044] Finally, the pressure applied to the T-shaped tube 3021 is removed, and the elastic element 3033 drives the T-shaped tube 3021 to move upward and reset, and simultaneously drives the two bellows 3032 to return to their initial positions. At this time, the implantation needle 3022 is also quickly pulled out of the patient's body, and the transmitter body 201 is removed. The transmitter body drives the T-shaped tube 3021, the implantation needle 3022, and the I-shaped piston rod 301, leaving the blood glucose sensor body 101 on the patient's skin. At this time, the soft hemostatic pad 103 and the soft protective deformation sleeve 104 are squeezed and completely adhered to the lower side of the transmitter on the blood glucose sensor body 101, and are fixed with the waterproof tape 102.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
