Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a sterilization component, an analyte detection transmitter and an analyte detection device. Background Art

[0002] In order to facilitate patients to monitor their own blood sugar parameters in real time, a technology that can be implanted into the subcutaneous tissue to continuously monitor human subcutaneous blood sugar has been developed on the market. This technology is achieved by inserting sensor electrodes into the subcutaneous tissue. The sensor electrodes undergo an oxidation reaction with glucose in the patient's body to form an electrical signal. The blood glucose monitor is also equipped with a transmitter, which transmits the electrical signal to an external receiver every 1 to 5 minutes. The receiver will display the corresponding blood sugar data and form a graph for reference by patients and doctors.

[0003] To ensure the safety of patients, the sensing electrodes and implantation needles are required to be sterile when inserted into the skin tissue. Most blood glucose monitoring devices on the market use irradiation sterilization to sterilize and disinfect the sensing electrodes and implantation needles to ensure that the sensing electrodes and implantation needles are sterile when implanted subcutaneously in the patient. In order to prevent the sensing electrodes and implantation needles from being contaminated after sterilization, they need to be sealed.

[0004] In order to solve the sealing problem of the sensor electrode and the implant needle, a sterilization assembly with a sterilization cavity has been developed on the market. By adding a fixing part and a sterilization shell, the sensor electrode and the implant needle are assembled together to seal the sensor electrode and the implant needle. However, the fixing part and the sterilization shell are mostly connected by threads or buckles, and the two are often loose, and the sealing cannot be guaranteed, resulting in sterilization failure of the sensor electrode and the implant needle. At the same time, the structural rationality of the fixing part in the prior art is poor, which makes it difficult to assemble the sensor electrode and the implant needle, and is not convenient for sterilization assembly processing.

[0057] Embodiment 1

[0058] This embodiment provides a sterilization component, which is used to solve the problems in the prior art that the various connecting parts of the sterilization component are prone to looseness, poor sealing, unreasonable structural design, difficult assembly between the parts, and low processing efficiency.

[0059] like Figures 1 to 3 As shown, the sterilization assembly provided in this embodiment includes an implantation needle assembly 1, a connector 2, a detection assembly, a fixing seat 4 and a sterilization shell 5. The implantation needle assembly 1 includes an implantation needle 10 and a needle handle 11. The implantation needle 10 is fixedly connected to the needle handle 11. A first sealing ring 110 is provided on the end of the needle handle 11 close to the implantation needle 10. The connector 2 is cylindrical with upper and lower openings. A first guide bevel 20 is provided on the inner wall of the connector 2. During assembly, the first sealing ring 110 can move along the first guide bevel 20 to the inside of the opening of the connector 2 and abut against the inner wall of the opening of the connector 2 to achieve a sealed connection between the needle handle 11 and the connector 2. By abutting the first sealing ring 110 against the inner wall of the opening of the connector 2, the problem of sealing failure due to loose connection can be avoided, and the sealing between the needle handle 11 and the connector 2 can be effectively guaranteed. The setting of the first guide bevel 20 allows the first sealing ring 110 to move smoothly along the first guide bevel 20 to the inside of the opening of the connector 2, which is convenient for assembling the connector 2 and the implant needle assembly 1, so that the structure of the implant needle assembly 1 and the connector 2 becomes simple, and the two are easy to assemble and process, so as to ensure the sealing degree of the connection between the two while reducing the processing cost of the two.

[0060] like Figure 1 and Figure 4 As shown, the sensing electrode 30 includes an internal body 301 and an external body 302. The internal body 301 penetrates into the patient's subcutaneous tissue, contacts and reacts with the glucose in the patient's body, and generates an electrical signal. The external body 302 can be placed in a fixing seat 4, so that the sensing electrode 30 can be fixed to ensure that the internal body 301 can be stably placed in the patient's subcutaneous tissue, thereby reducing the pain felt by the patient during use.

[0061] To facilitate the assembly of the sensing electrode 30, a guide groove 101 is further provided on the implant needle 10. The inner part 301 of the sensing electrode 30 is placed in the guide groove 101. When the implant needle 10 punctures the subcutaneous tissue of the patient, the inner part 301 will also be penetrated into the subcutaneous tissue of the patient at the same time, making the assembly of the implant needle 10 and the sensing electrode 30 more rational and improving the convenience of patient operation.

[0062] The fixing seat 4 is sealed and connected to the connecting piece 2. A through hole 40 is provided on the fixing seat 4 for the insertion of the implant needle 10 and the interior of the body 301. After the assembly is completed, the sensing electrode 30 is installed between the fixing seat 4 and the connecting piece 2. In this way, when actually assembling the sterilization component, the processing personnel can assemble the connecting piece 2 after assembling the sensing electrode 30 and the fixing seat 4. In this way, the problem of difficult assembly of the sensing electrode 30 can be solved, so as to further speed up the assembly efficiency of the sterilization component by the staff.

[0063] The sterilization shell 5 is used to accommodate the implant needle 10 and the body interior 301. The sterilization shell 5 is sealed and connected to the fixed seat 4. Specifically, a second guide bevel 401 is provided on the inner wall ring of the through hole 40, and a second sealing ring 50 is provided at one end of the sterilization shell 5 close to the fixed seat 4. During assembly, the second sealing ring 50 can move along the second guide bevel 401 to the inside of the through hole 40 and abut against the inner wall of the through hole 40 to achieve a sealed connection between the sterilization shell 5 and the fixed seat 4. The second sealing ring 50 and the inner wall of the through hole 40 abut against each other to achieve a technical solution of a sealed connection between the sterilization shell 5 and the fixed seat 4, which simplifies the overall structure of the sterilization component and enables rapid assembly and processing.

[0064] As preferably, Figure 1 , Figure 2 and Figure 5 As shown, a first ridge 21 is further provided on the inner wall of the connector 2, and the first ridge 21 is interconnected with the first guide slope 20. During assembly, the first sealing ring 110 will move along the first guide slope 20 to the bottom of the first ridge 21 and abut against the first ridge 21. The setting of the first ridge 21 can block the first sealing ring 110, further preventing the first sealing ring 110 from detaching from the connector 2, thereby strengthening the tightness of the seal between the implant needle assembly 1 and the connector 2. Of course, the first ridge 21 can be selectively set according to the volume and overall structure of the sterilization assembly itself, and there is no specific limitation.

[0065] As preferably, Figure 2 and Figure 8 As shown, a second ridge 402 is further provided on the inner wall of the through hole 40, and the second ridge 402 is interconnected with the second guide slope 401. During assembly, the second sealing ring 50 will move along the second guide slope 401 to the bottom of the second ridge 402 and abut against the second ridge 402. The setting of the second ridge 402 can block the second sealing ring 50, further preventing the second sealing ring 50 from detaching from the fixing seat 4, thereby strengthening the tightness of the seal between the fixing seat 4 and the sterilization shell 5. Of course, the second ridge 402 can be selectively set according to the volume and overall structure of the sterilization component itself, and there is no specific limitation.

[0066] Preferably, in order to prevent relative movement between the implant needle assembly 1 and the connector 2, thereby affecting the sealing between the two, Figure 5 As shown, a positioning groove 25 is provided on the inner wall of the connecting member 2, and a corresponding protrusion is provided on the needle handle 11. During assembly, the protrusion is clamped in the positioning groove 25 to realize the positioning of the assembly of the implant needle assembly 1 and the connecting member 2.

[0067] In this embodiment, Figure 1 and Figure 3As shown, the fixing seat 4 is also provided with an electrode groove 41, which is located on the side of the through hole 40. When the inner body 301 of the sensing electrode 30 passes through the through hole 40 along with the implant needle 10, the outer body 302 is accommodated in the electrode groove 41, which can make the sterilization component structure more compact, and can also protect the sensing electrode 30 to ensure the service life and performance of the sensing electrode 30. At the same time, in order to further improve the protection and sealing degree of the outer body 302, a snap-fit ​​plate can be optionally provided at the place corresponding to the electrode groove 41 on the connecting member 2, and the snap-fit ​​plate snaps the outer body 302 into the electrode groove 41. The setting of the snap-fit ​​plate can be selectively set according to the actual structure of the sterilization component, and there is no specific limitation.

[0068] Regarding the sealing connection between the connecting member 2 and the fixing seat 4, Figures 5 to 7 As shown in the figure, an annular groove 42 is provided on one side of the fixing seat 4 close to the connecting member 2, and an annular ridge 22 is correspondingly provided on the bottom surface of the connecting member 2. The annular ridge 22 can be accommodated in the annular groove 42, which can make the connection between the connecting member 2 and the fixing seat 4 tighter and ensure the stable connection between the connecting member 2 and the fixing seat 4.

[0069] At the same time, the annular groove 42 is connected to the electrode groove 41 through the connecting groove 43, and a connecting portion 26 is correspondingly provided on the bottom surface of the connector 2, so that the sensing electrode 30 can be assembled between the fixing seat 4 and the connector 2, making the structure of the sterilization component more compact, and the sealing degree of the connection between the fixing seat 4 and the connector 2 can be ensured, further improving the sealing of the sterilization component. After the connector 2 and the fixing seat 4 are assembled, the connecting portion 26 on the connector 2 will be accommodated in the connecting groove 43, which can limit the assembly of the connector 2 and the fixing seat 4, prevent the connector 2 and the fixing seat 4 from relative movement, so as to improve the sealing between the connector 2 and the fixing seat 4, and further ensure the sealing of the sterilization component as a whole.

[0070] Preferably, in order to further enhance the sealing between the fixing seat 4 and the connecting member 2, a sealing colloid may be filled in the annular groove 42, and then the connecting member 2 and the fixing seat 4 are assembled to further block the air from entering the sterilization assembly through the connecting member 2 and the fixing seat 4.

[0071] In order to facilitate the accurate positioning and assembly of the connecting member 2 and the fixing seat 4, Figure 1 and Figure 5 As shown, two limiting portions 23 can be set at the bottom of the connecting member 2 and spaced apart from each other. Specifically, the spacing distance between the two limiting portions 23 can be set with reference to the width of the electrode groove 41. When the connecting member 2 and the fixing seat 4 are assembled, the electrode groove 41 is limited between the two limiting portions 23. In this way, the limiting portions 23 can position the fixing seat 4 and the connecting member 2, thereby realizing precise assembly of the connecting member 2 and the fixing seat 4 and improving the assembly efficiency of the assemblers.

[0072] To improve the safety of patients, Figure 6 As shown, in this embodiment, a blocking plate 24 is preferably provided at the opening at the lower end of the connecting member 2, and a positioning opening 240 is provided on the blocking plate 24. Figure 1 and Figure 3 As shown, the implant needle 10 and the internal body 301 are placed in the sterilized shell 5 through the positioning port 240. When the patient detects his own blood sugar parameters, the implant needle 10 needs to be punctured into the patient's subcutaneous tissue, and the internal body 301 of the sensing electrode 30 will be punctured into the subcutaneous tissue. Then the patient pulls out the implant needle 10, at which time the sensing electrode 30 will be left behind, and the internal body 301 will remain in the patient's subcutaneous tissue, so as to realize the glucose reaction between the sensing electrode 30 and the patient's subcutaneous tissue and continuously generate electrical signals. After the implant needle 10 is withdrawn, the internal body 301 will completely puncture the patient's subcutaneous tissue. The setting of the positioning port 240 can reduce the contact area between the patient's puncture port and the external space, thereby ensuring the sterility of the internal body 301 and improving the safety of the patient's use.

[0074] The second embodiment of the present invention provides an analyte detection transmitter, including the sterilization component in the first embodiment, such as Fig. 9 As shown, the analyte detection transmitter also includes a shell assembly and a detection circuit board 7, wherein the shell assembly is used to fix the sterilization assembly, and can also further seal the joints of the components in the sterilization assembly to ensure the overall sealing of the sterilization assembly, and the sensing electrode 30 will be accommodated in the snap-fit ​​space of the shell assembly. The setting of the shell assembly can prevent the sensing electrode 30 from directly contacting the external environment, and the problem of sterilization and sealing failure of the sensing electrode 30 during the assembly process occurs, so that the performance of the sensing electrode 30 is more stable, thereby ensuring the performance of the analyte detection transmitter, improving the patient's user experience, and ensuring the accuracy of the patient's blood glucose parameter detection.

[0075] Specifically, a first mounting hole 71 and a second mounting hole 72 are provided on the detection circuit board 7. In actual assembly, the connector 2 is inserted into the first mounting hole 71, and a protruding column 410 is provided outside the electrode slot 41 of the fixing seat 4. The protruding column 410 is inserted into the second mounting hole 72. In this way, the detection circuit board 7 can be assembled with the sterilization component, making the overall structure of the analyte detection transmitter more compact and more convenient for patients to carry. At the same time, during assembly, the protruding column 410 is inserted into the second mounting hole 72. The provision of the second mounting hole 72 can prevent the detection circuit board 7 from shaking, further improve the overall structural stability of the sterilization component, and improve the reliability of the connection between the sensing electrode 30 and the detection circuit board 7. Among them, a plurality of connection terminals 303 are provided on the sensing electrode 30, so that the sensing electrode 30 is connected to the detection circuit board 7, and the electrical signal generated on the sensing electrode 30 is transmitted to the detection circuit board 7. An electrical signal transmitting module (not shown in the figure) is provided on the detection circuit board 7. The electrical signal transmitting module and the external electrical signal conversion device are connected by Bluetooth transmission, so that the electrical signal generated by the reaction between the sensing electrode 30 and the glucose in the patient's subcutaneous tissue is transmitted to the external electrical signal conversion device in real time, so as to realize real-time detection of the patient's blood sugar and improve the patient's use experience. Among them, the external electrical signal conversion device can be a mobile phone with an electrical signal conversion function, an electronic watch or a mechanical device in the medical field, and no specific restrictions are made here.

[0076] Preferably, the detection component also includes a power supply 8, which is connected to the detection circuit board 7 to supply power to the detection circuit board 7, so that the working time of the sensing electrode 30 can be guaranteed. At the same time, a charging port can be provided, and the power supply 8 can be charged through the external charging port to realize the recycling of the power supply 8 and reduce energy waste.

[0077] Exemplarily, the sterilization assembly includes an upper shell 61 and a lower shell 62. During actual assembly, the detection assembly, the connector 2 and the fixing seat 4 are placed in the space where the upper shell 61 and the lower shell 62 are buckled. Fig.10 As shown, the lower shell 62 is provided with a fixing groove 620. After the sterilization component is assembled, the connecting piece 2 and the fixing seat 4 are placed in the fixing groove 620. The fixing groove 620 can further seal the connection between the connecting piece 2 and the fixing seat 4 to improve the sealing between the two. The inner wall of the fixing groove 620 also has a semicircular groove 621 for placing the protruding column 410. After the sterilization component is assembled, the protruding column 410 is clamped in the semicircular groove 621, which can locate the assembly position of the lower shell 62 to avoid loosening of the lower shell 62 after assembly, thereby further improving the stability of the sterilization component.
