[0002] The dynamic blood glucose monitoring system CGM is a system used to monitor the blood glucose index of the human body. The dynamic blood glucose monitoring system CGM in the existing technology is to send the sensor into the subcutaneous tissue of the human body. The enzyme on the sensor reacts with the subcutaneous tissue fluid to detect the blood glucose value, and cooperates with the transmitter to send the blood glucose value to the terminal, so as to realize real-time dynamic monitoring of blood glucose conditions. The dynamic blood glucose monitoring system CGM only needs to be implanted once, and then it can continuously monitor the blood glucose data in the body through Bluetooth connection, eliminating the pain of frequent needle sticks of traditional blood glucose meters, and making up for the tedious operation of traditional blood glucose meters that can only monitor once. For the dynamic blood glucose monitoring system CGM, the implantation tool for implanting the blood glucose sensor is one of the indispensable devices. The implantation tool can be used to simply and quickly implant the sensor and transmitter into the human body.

[0003] In existing technology, some sensors are directly assembled with the transmitter during the production process, forming a complete transmitter assembly. When the user subsequently operates the implant tool, the implant tool directly pushes the transmitter assembly, thereby implanting the sensor and transmitter into the human body.

Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of this application.

[0044] The utility model provides a sensor assembly, which includes a sensor fixing seat and a sensor; the top of the sensor fixing seat is recessed to form a glue groove for accommodating fixing glue; the sensor is arranged on the sensor fixing seat, and the detection end of the sensor is located outside the sensor fixing seat. The sensor fixing seat is provided in the sensor assembly, and the sensor fixing seat is provided with the glue groove, so that when installing the sensor, the sensor can be assembled with the sensor fixing seat first, and then the sensor fixing seat can be assembled with the transmitter. Through the fixing glue in the glue groove, the sensor fixing seat only needs to be docked and inserted with the transmitter to complete the connection and fixation between the sensor and the transmitter, which simplifies the assembly method and improves the assembly efficiency. After the sensor fixing seat and the transmitter are docked, the fixing glue can also fix the position well, and can also stabilize the qualified rate of the product after the assembly is completed.

[0045] Please refer to Figure 1 and Figure 2 In one embodiment, a sensor assembly 100 is provided, which includes a sensor fixing seat 10 and a sensor 20. The top 11 of the sensor fixing seat 10 is recessed to form a glue-containing groove 12 for accommodating fixing glue. That is, a glue-containing groove 12 is provided on the top 11 of the sensor fixing seat 10, and the glue-containing groove 12 is used to accommodate fixing glue. When assembling the sensor assembly 100, fixing glue can be injected into the glue-containing groove 12, and then the sensor fixing seat 10 can be connected and fixed with other components through the contained fixing glue. The sensor 20 is provided on the sensor fixing seat 10, and the detection end 201 of the sensor 20 is located outside the sensor fixing seat 10. The detection end 201 of the sensor 20 refers to the part of the sensor 20 that needs to be implanted in the human body, that is, the part that will eventually be left under the human epidermis and in contact with blood after the user operates the implantation tool.

[0046] Understandably, the connection structure between the sensor and the transmitter in the prior art is relatively complex, making assembly more difficult, impacting assembly efficiency, and also, to a certain extent, affecting the qualified rate of the finished product. Furthermore, since the sensor ultimately needs to be partially implanted in the human body, it is necessary to ensure that the sensor does not easily move after assembly to ensure that it can be successfully implanted under the human epidermis during subsequent implantation. To ensure that the sensor's position does not change, some prior art even incorporates additional fixing structures to secure the sensor, further increasing assembly difficulty and reducing assembly efficiency.

[0047] In the sensor assembly 100 provided in this embodiment, the sensor 20 is disposed on the sensor holder 10, and the top 11 of the sensor holder 10 is provided with the adhesive groove 12. When assembling the sensor 20, it is only necessary to install the sensor 20 on the sensor holder 10, and then the sensor holder 10 can be directly inserted into the corresponding position on the transmitter to assemble the sensor 20, thereby simplifying the assembly method and improving assembly efficiency. Since the adhesive groove 12 is injected with fixing glue, the position of the sensor assembly 100 can be fixed by the fixing glue after assembly, thereby stabilizing the qualified rate of the product after assembly.

[0048] It is understood that in order to reduce the difficulty of assembling the sensor 20 and the sensor holder 10, and to ensure that the sensor 20 can be installed in the sensor holder 10 in the desired orientation and posture, preferably, in one embodiment, a limiting wall 13 can be provided in the sensor holder 10. The limiting wall 13 is used to abut against the side of the sensor 20, thereby limiting the position of the sensor 20 and reducing the difficulty of installing the sensor 20. At the same time, after the sensor 20 is installed in the sensor holder 10, the limiting wall 13 can also limit the position of the sensor 20, preventing the sensor 20 from swinging and shifting, ensuring the position and posture of the sensor 20, and facilitating subsequent assembly and docking with other components.

[0049] Preferably, in one embodiment, the sensor 20 is at least partially located in the glue groove 12 , so that the fixing glue in the glue groove 12 can also fix the sensor 20 , thereby better ensuring the position and posture of the sensor 20 .

[0050] Preferably, in one embodiment, the sensor 20 passes through the adhesive groove 12. That is, the sensor 20 passes through the adhesive groove 12, and both ends of the sensor 20 are located outside the adhesive groove 12. By passing the sensor 20 through the adhesive groove 12, when the sensor holder 10 is assembled with the transmitter, a corresponding structure can be provided on the transmitter to squeeze the fixing glue in the adhesive groove 12, so that the fixing glue flows in the adhesive groove 12 to fill all gaps, thereby achieving a sealed and bacteria-proof sensor 20.

[0051] Preferably, in one embodiment, a side edge 14 of the sensor holder 10 is provided with an escape portion 15, and the escape portion 15 is in communication with the glue containing groove 12. The connection end 202 of the sensor 20 extends out of the sensor holder 10 through the escape portion 15, and the connection contact 203 of the connection end 202 is located outside the sensor holder 10. The connection end 202 of the sensor 20 refers to the portion of the sensor 20 that needs to be connected to the electronic components in the transmitter, and the connection contact 203 is the contact for contacting the electronic components. That is to say, in this embodiment, the portion of the sensor 20 for connecting with the electronic components is located outside the sensor holder 10, so that during the assembly process, the electronic components do not need to extend into the sensor holder 10 to connect with the sensor 20, thereby reducing the difficulty of assembly.

[0052] Specifically, in one embodiment, the adhesive holding groove 12 is an annular groove, which is more conducive to the flow of the fixing adhesive during the extrusion process. A through hole 19 is defined at the center of the sensor holder 10, through which the sensor 20 passes. The aperture of the through hole 19 needs to be larger than the portion through which the sensor 20 passes, thereby facilitating the insertion of the implant needle.

[0053] Specifically, in one embodiment, the avoidance portion 15 is formed to be recessed from the top 11 , so that the sensor 20 can be directly inserted into the sensor fixing seat 10 from the side of the top 11 , making assembly more convenient.

[0054] Preferably, in one embodiment, the connection end 202 of the sensor 20 is arranged vertically, and the connection contact 203 of the connection end 202 is located outside the sensor holder 10. The vertical arrangement of the connection end 202 means that the arrangement direction of the connection end 202 is along the vertical direction rather than the horizontal direction, that is, in this embodiment, the connection end 202 is placed upright on the sensor holder 10, and the connection contact 203 is located outside the sensor holder 10. For example, Figure 1In the illustrated embodiment, the connection end 202 is arranged in a direction perpendicular to the top 11 of the sensor fixing base 10 in the vertical direction. After assembly, the top 11 can be fitted with the inner wall of the transmitter cover, so that the connection end 202 stands upright in the transmitter cover. When the electronic components are subsequently assembled, the connection end 202 can be vertically inserted into the socket of the electronic components, thereby reducing the difficulty of subsequent assembly between the electronic components and the sensor 20.

[0055] Preferably, in one embodiment, the top 11 of the sensor holder 10 is provided with a first guide and positioning portion 16. When the sensor holder 10 is assembled with the transmitter, the first guide and positioning portion 16 can cooperate with a corresponding structure on the transmitter, thereby serving as a guide and limiter to ensure the installation direction and angle of the sensor holder 10 and reduce the difficulty of assembly. Specifically, in one embodiment, the first guide and positioning portion 16 is a guide and positioning groove formed by a depression in the top 11.

[0056] Preferably, in one embodiment, the detection end 201 of the sensor 20 extends out of the sensor holder 10 from the bottom 17 of the sensor holder 10, and the bottom 17 of the sensor holder 10 is provided with a detachable connection structure 18. The provision of the detachable connection structure 18 facilitates detachable connection with other structures. For example, in one embodiment, a sealing sleeve can be assembled at the bottom of the sensor holder 10, thereby achieving sealed protection for the sensor 20 and the implant needle. The detachable connection structure 18 can adopt any structure that can achieve detachable connection between components, such as a thread, a snap, a hanging platform and the like. In one embodiment, the detachable connection structure 18 is specifically a hanging platform structure, and the sealing sleeve can be connected to the bottom of the sensor holder 10 through the hanging platform structure, and the sealing sleeve can be removed from the sensor holder 10 by rotating the sealing sleeve, thereby achieving a detachable connection between the two.

[0057] Please refer to Figures 3 to 9At the same time, in one embodiment, a transmitter assembly 1000 is also provided, which includes the sensor assembly 100, as well as a transmitter upper cover 300, a transmitter lower cover 200, and electronic components 400. A connecting protrusion 311 is provided on the inner wall 31 of the transmitter upper cover 300, which matches the adhesive groove 12. The connecting protrusion 311 extends into the adhesive groove 12. The matching of the connecting protrusion 311 with the adhesive groove 12 means that the shape and size of the connecting protrusion 311 are consistent, so that during assembly, the connecting protrusion 311 can smoothly extend into the adhesive groove 12. The provision of the connecting protrusion 311 allows the connecting protrusion 311 to squeeze the fixing adhesive in the adhesive groove 12 during assembly. The sensor fixing base 10 is connected and fixed to the transmitter upper cover 300 via the fixing adhesive in the adhesive groove 12. The transmitter lower cover 200 is connected to the transmitter upper cover 300. The electronic component 400 is disposed in a space enclosed by the transmitter lower cover 200 and the transmitter upper cover 300 , and is connected to the connection contact 203 of the connection end 202 of the sensor 20 .

[0058] In one embodiment, when assembling the transmitter assembly 1000, liquid fixing glue can be first injected into the glue reservoir 12, and then the sensor 20 can be placed on the sensor holder 10. The sensor holder 10 can then be docked with the transmitter upper cover 300. Through the action of the connection protrusions 311, the liquid fixing glue is squeezed to fill all gaps, thereby achieving a sealed and bacteria-proof condition for the sensor 20. After the assembly is completed and the sensor 20 is sterilized, the connection socket of the electronic component 400 is aligned and inserted into the connection end 202, thus completing the connection between the sensor 20 and the electronic component 400. Subsequently, only the transmitter lower cover 200 and the transmitter upper cover 300 need to be assembled and sealed to complete the assembly of the entire transmitter assembly 1000.

[0059] Understandably, since the sensor needs to be implanted in the human body, sterilization is required. Currently, the sensor and implant needle are assembled into a single sterilized body. After sterilization, the body is then docked with the transmitter. Ideally, the sterilized body and transmitter are securely connected and positioned. However, due to errors caused by various factors such as production and assembly, gaps may exist between the sterilized body and transmitter after assembly, affecting subsequent use.

[0060] When sterilizing the transmitter assembly 1000 provided in this embodiment, the transmitter upper cover 300, the sensor assembly 100, the sealing sleeve 500, and the implant needle assembly 600 can be first formed into an integral sterilized body for sterilization. In the subsequent assembly process, only the electronic components 400 and the transmitter lower cover 200 need to be installed, thereby better avoiding the above-mentioned assembly problems.

[0061] Specifically, in one embodiment, the fixing glue may be UV glue (shadowless glue). After the sensor fixing base 10 is connected to the transmitter cover 300 , the fixing glue may be converted into a solid state by ultraviolet irradiation.

[0062] Preferably, in one embodiment, the electronic component 400 includes a circuit board 41, a power supply unit 42, and a connection socket 43. The power supply unit 42 is connected to the circuit board 41, and the connection socket 43 is connected to the circuit board 41. The circuit board 41 can be a printed circuit board assembly (PCBA), and the power supply unit 42 can be a battery. The connection socket 43 includes a socket body 431 and a connection terminal 432 disposed on the socket body 431. The socket body 431 defines a vertical slot 4311. The connection end 202 of the sensor 20 is inserted into the vertical slot 4311, and the connection contact 203 is connected to the connection terminal 432.

[0063] Preferably, in one embodiment, the inner wall 31 of the transmitter upper cover 300 is provided with a second guide and positioning portion 32, which mates with the first guide and positioning portion 16 of the sensor holder 10. The second guide and positioning portion 32 mates with the first guide and positioning portion 16 in that the two can cooperate with each other for positioning, and their shapes and sizes match. Specifically, in one embodiment, the second guide and positioning portion 32 is a guide and positioning protrusion, while the first guide and positioning portion 16 is a guide and positioning groove.

[0064] It is understandable that the placement of the sensor will determine the shape of the sensor and the assembly method of the sensor mating parts, and at the same time determine whether the sealing, antibacterial and other properties of the structural sensor meet the adjustment requirements. In one embodiment, by forming the sensor 20 and the sensor holder 10 into an assembly and connecting it to the transmitter cover 300, an independent irradiation sterilization method can be adopted, while taking into account that the sensor 20 cannot be damaged by pressure during the assembly process, ensuring that the connection socket 43 on the circuit board 41 can enable the sensor 20 to be smoothly inserted, and the sensor 20 will not be offset or damaged. At the same time, during subsequent use, it can also ensure that the sensor 20 remains fixed during the retraction of the implant needle. It can also meet the sealing requirements of the sensor 20, so that water molecules cannot enter the transmitter and the socket along the sensor 20.

[0065] The above is only an embodiment of the present invention. It should be pointed out that those skilled in the art can make improvements without departing from the inventive concept of the present invention, but these improvements are all within the scope of protection of the present invention.
