[0025] Please refer to Figures 1 to 4 As shown, the present invention proposes a blood glucose detection device 100, which includes a fixing component 1 and a detection component 2. The fixing component 1 is provided with an adhesive tape 11, and the adhesive tape 11 is configured to be adhered to the user's skin. The detection component 2 is detachably connected to the fixing component 1, and the detection component 2 is provided with a detection surface 221, and the detection surface 221 is configured to contact the user's skin to detect the blood glucose level.

[0026] In this embodiment, the blood glucose detection device 100 is a medical device that can monitor the user's blood glucose level. The blood glucose detection device 100 can continuously and in real time monitor the changes in daily blood glucose of diabetic patients and record blood glucose data in real time. It is widely used in daily blood glucose management of diabetic patients. This application achieves continuous blood glucose detection by attaching the blood glucose detection device 100 to the skin.

[0027] Specifically, if Figure 1 As shown, the blood glucose detection device 100 includes a fixing component 1 and a detection component 2. The fixing component 1 is usually attached to and abutted against human skin, such as the upper arm or abdomen. The detection component 2 can be detachably connected to the fixing component 1, and a probe or a detection electrode is arranged inside the detection component 2. By modifying the probe or the detection electrode with glucose oxidase, the glucose oxidase reacts with glucose in the tissue fluid to measure the glucose concentration in the tissue fluid, and the detected glucose concentration is converted into an electrical signal. The blood glucose detection device 100 transmits the obtained electrical signal about the glucose concentration to an external signal receiving device, such as a smart phone, a smart watch, a dedicated monitor, etc., to facilitate users to view, analyze, and trace back data.

[0028] In this embodiment, the fixing component 1 is the main supporting structure of the blood glucose detection device 100. The main structure of the fixing component 1 can be a plate-like structure, a seat structure, a platform structure, a shell structure, etc., which is not limited here. The fixing component 1 is provided with an adhesive tape 11. The adhesive tape 11 has an adhesive surface 111. The adhesive surface 111 faces the user's skin side, and when the user wears the sensor, the adhesive surface 111 contacts and adheres to the user's skin.

[0029] At the same time, the detection component 2 and the fixed component 1 can be detachably connected. When the detection component 2 is connected to the fixed component 1, the detection component 2 is limitedly connected to the fixed component 1, so that the detection surface 221 provided on the detection component 2 can abut against the user's skin and detect the user's blood sugar level.

[0030] It can be understood that by configuring the detection component 2 and the fixing component 1 as a detachable structure and fixing and bonding the user's skin via the fixing component 1, the fixing component 1 can, on the one hand, limit and fix the detection component 2 on the user's skin surface to ensure that the detection component 2 stably and continuously detects the user's blood sugar level; on the other hand, when the adhesion of the adhesive tape 11 of the fixing component 1 decreases, the fixing component 1 and the detection component 2 can be directly separated, and then a new fixing component 1 can be directly replaced without replacing the detection component 2, thereby reducing or avoiding the replacement of the detection component 2, thereby ensuring the continuous and stable operation of the detection component 2 and effectively reducing the use cost of the blood sugar detection device 100.

[0031] The blood glucose detection device 100 of the present technical solution includes a fixing component 1 and a detection component 2, the fixing component 1 is provided with an adhesive tape 11, the adhesive tape 11 is configured to be adhered to the user's skin, the detection component 2 is detachably connected to the fixing component 1, the detection component 2 is provided with a detection surface 221, the detection surface 221 is configured to contact the user's skin to detect the blood glucose level, and by arranging the detection component 2 for detecting the user's blood glucose level and the fixing component 1 for bonding the user's skin as a detachable structure, on the basis of ensuring the blood glucose detection accuracy of the detection component 2, the positioning of the detection component 2 by the fixing component 1 and the bonding of the fixing component 1 to the user's skin can be achieved simultaneously, without the need for bonding the detection component 2 to the user's skin, thereby avoiding the replacement of the detection component 2 due to the decrease in adhesion, thereby improving the service life of the detection component 2, ensuring the continuous operation of the detection component 2, and reducing the use cost of the blood glucose detection device 100.

[0032] In one embodiment, if Figures 1 to 4 As shown, the fixing component 1 includes a fixing body 12 and an adhesive tape 11 , and the adhesive tape 11 is arranged on the periphery of the fixing body 12 ; the detection component 2 is detachably connected to the fixing body 12 , and the adhesive tape 11 is arranged around the detection component 2 .

[0033] In this embodiment, the fixed body 12 is the main supporting structure of the fixed component 1 and the blood glucose detection device 100. The fixed body 12 can be a plate body, a frame body, a shell, a trough body, a rack body, a table body and other structures. The adhesive tape 11 is arranged at the peripheral position of the fixed body 12. For example, a protruding adhesive portion is provided at the periphery of the fixed body 12, one side of the adhesive tape 11 is adhered to the adhesive portion, and the side of the adhesive tape 11 facing away from the adhesive portion is adhered to the user's skin.

[0034] At the same time, the detection component 2 and the fixed body 12 can be detachably connected, such as by magnetic connection, snap connection, slot plug-in connection, threaded connection, etc., and the adhesive tape 11 is set around the detection component 2.

[0035] It can be understood that by arranging the detection component 2 and the fixed body 12 to be detachably connected, when the adhesive force of the adhesive tape 11 decreases and is not sufficient to make the detection component 2 stick closely to the user's skin for blood glucose testing, the fixed body 12 can be separated, disassembled and replaced separately, and the detection component 2 can be retained to reduce or even avoid replacement of the detection component 2, thereby ensuring continuous and stable operation of the detection component 2 and effectively reducing the use cost of the blood glucose testing device 100.

[0036] Furthermore, the adhesive tape 11 is arranged around the detection component 2. Preferably, the circle where the adhesive tape 11 and the fixed body 12 are adhered is circular, thereby ensuring that the detection component 2 surrounded by the adhesive tape 11 can be located at the central position of the adhesive tape 11, so that the limiting position and the abutting force of the fixed body 12 on various parts of the detection component 2 can be consistent, and the detection surface 221 of the detection component 2 can abut against the user's skin surface at various places, so as to ensure the accuracy and stability of blood sugar detection by the detection component 2.

[0037] In one embodiment, if Figure 2 and Figure 3 As shown, the fixing body 12 is provided with a mounting groove 121 , and the adhesive tape 11 is arranged at the periphery of the groove of the mounting groove 121 ; the detection component 2 is limited in the mounting groove 121 .

[0038] It can be understood that the fixed body 12 is a shell or a platform structure, and a mounting groove 121 is provided on the fixed body 12. Preferably, the groove cross-section of the mounting groove 121 is circular, and the adhesive tape 11 is arranged at the periphery of the groove of the mounting groove 121. At the same time, the detection component 2 can be detachably arranged in the mounting groove 121, and can be detached from the fixed body 12 from the groove of the mounting groove 121. At the same time, a contact surface 2111 is provided on the side of the detection component 2 facing away from the detection surface 221, and the contact surface 2111 can be limited to contact with at least part of the bottom wall of the mounting groove 121, and can also be limited to contact with the mounting groove. The side wall of the mounting groove 121, firstly, limits the detection component 2 in a direction perpendicular to the detection surface 221 through the joint action of the mounting groove 121 and the adhesive tape 11, so that the detection surface 221 of the detection component 2 is pressed against the user's skin. At the same time, the side wall of the mounting groove 121 can also limit the detection component 2 in a direction parallel to the detection surface 221, to ensure that the detection component 2 will not translate in the direction of the detection surface 221, so as to enhance the limiting and positioning capabilities of the fixed body 12 and the mounting groove 121 on the detection component 2, and ensure the stability and accuracy of the detection component 2 in detecting blood sugar levels.

[0039] In one embodiment, if Figure 2 and Figure 3 As shown, the detection component 2 is magnetically connected to at least a portion of the bottom wall of the mounting groove 121. Optionally, the detection component 2 is magnetically connected to at least a portion of the side wall of the mounting groove 121. It can be understood that the detection component 2 and the fixed body 12 are magnetically connected via magnetic parts, such as the detection component 2 is magnetically connected to at least a portion of the bottom wall of the mounting groove 121, or the detection component 2 is magnetically connected to the side wall of the mounting groove 121, so as to improve the separability between the detection component 2 and the fixed body 12, realize the rapid separation and installation between the detection component 2 and the fixed body 12, improve the convenience of use, and also facilitate one-handed operation.

[0040] Optionally, the distance between the detection surface 221 and the bottom wall of the mounting groove 121 is greater than the distance between the adhesive surface 111 of the adhesive tape 11 and the bottom wall of the mounting groove 121; it is understandable that the detection surface 221 protrudes from the notch of the mounting groove 121 by a certain thickness, so that the distance between the detection surface 221 and the bottom wall of the mounting groove 121 is greater than the distance between the adhesive surface 111 of the adhesive tape 11 and the bottom wall of the mounting groove 121, so that when the adhesive surface 111 of the adhesive tape 11 is adhered to the user's skin, the detection surface 221 first contacts the user's skin, and the detection component 2 can compress the skin in contact with the detection surface 221, so that the detection surface 221 is pressed against the user's skin, thereby improving the contact between the probe or detection electrode provided on the detection surface 221 of the detection component 2 and the user's skin, thereby ensuring the accuracy and stability of the detection component 2 when measuring blood sugar levels.

[0041] In one embodiment, the detection component 2 is provided with a first thread, and the inner wall of the installation groove 121 is provided with a second thread; the first thread and the second thread are threadedly connected.

[0042] It can be understood that the main structure of the detection component 2 is set as a circular structure, such as the outer shell of the detection component 2 is a cylindrical structure, and a first thread is set on the outside of the detection component 2, the installation groove 121 corresponds to a circular groove, and a second thread is set on the inner wall of the installation groove 121, and the first thread and the second thread are threadedly connected to achieve a quick and detachable connection between the detection component 2 and the fixed body 12, and through the connection between the first thread and the second thread, the fixed body 12 can limit and fix the detection component 2 in a direction perpendicular to the detection surface 221 and in a direction parallel to the detection surface 221, so as to ensure that when the fixed body 12 is bonded to the user's skin, the position of the detection component 2 is determined, and the contact position of the detection surface 221 with the skin is fixed, thereby improving the detection accuracy and stability.

[0043] In one embodiment, the fixing assembly 1 further includes a limiting protrusion, which is disposed on the inner wall of the mounting groove 121 ; the height of the limiting protrusion protruding from the inner wall of the mounting groove 121 gradually increases along the groove depth direction of the mounting groove 121 .

[0044] It can be understood that the limiting protrusion is arranged on the inner wall of the mounting groove 121, and a guide surface is provided on the side of the limiting protrusion away from the inner wall of the mounting groove 121, and the guide surface is arranged at an angle to the inner wall of the mounting groove 121, so that the height of the limiting protrusion protruding from the inner wall of the mounting groove 121 gradually increases along the groove depth direction of the mounting groove 121, that is, the height of the limiting protrusion protruding from the inner wall of the mounting groove 121 gradually increases from the groove mouth of the mounting groove 121 to the bottom wall of the mounting groove 121, so that when the detection component 2 extends into the mounting groove 121, the main structure of the detection component 2 can gradually press against the limiting protrusion to ensure that the position of the detection component 2 in the mounting groove 121 is fixed, and the detection component 2 is prevented from being displaced in the direction parallel to the detection surface 221, so as to improve the detection accuracy and stability.

[0045] In one embodiment, if Figures 2 to 4 As shown, the detection component 2 includes a transmitter module 21 and a sensor module 22. The sensor module 22 is provided with a detection surface 221. The transmitter module 21 and the sensor module 22 can be detachably connected.

[0046] In this embodiment, the detection component 2 includes a transmitter module 21 and a sensor module 22. The sensor module 22 is provided with a detection surface 221. The sensor module 22 is usually attached to human skin, such as the upper arm or abdomen, and glucose oxidase is arranged inside the sensor module 22. The glucose oxidase can react with glucose in the tissue fluid to measure the glucose concentration in the tissue fluid and convert the detected glucose concentration into an electrical signal. The transmitter module 21 is electrically connected or communicatively connected to the sensor module 22 to obtain the electrical signal about the glucose concentration in the sensor module 22, and at the same time, the acquired blood sugar data is wirelessly transmitted to an external signal receiving device, such as a smart phone, a smart watch, a dedicated monitor, etc., to facilitate users to view data, analyze data, trace data, etc.

[0047] It can be understood that the transmitter module 21 and the sensor module 22 can be detachably connected so that after the glucose oxidase in the sensor module 22 is exhausted, the sensor module 22 can be replaced separately without being replaced or discarded together with the transmitter module 21. On the one hand, the overall ease of use of the detection component 2 is improved, and it is convenient to disassemble it separately for maintenance, cleaning and repair. On the other hand, the transmitter module 21 can continue to be used, further reducing the cost of use.

[0048] In one embodiment, if Figure 2 and Figure 4 As shown, the fixing component 1 is provided with a first magnetic group 13, the transmitter module 21 is provided with a second magnetic group 212, and the sensor module 22 is provided with a third magnetic group 222; the second magnetic group 212 is located between the first magnetic group 13 and the third magnetic group 222, and the second magnetic group 212 is magnetically connected to the third magnetic group 222 and the first magnetic group 13.

[0050] Among them, the first magnetic group 13, the second magnetic group 212 and the third magnetic group 222 all include a plurality of magnetic members, and the plurality of magnetic members are evenly distributed at positions corresponding to each other among the fixed body 12, the sensor body and the transmitter body 211, and the second magnetic group 212 is located between the first magnetic group 13 and the third magnetic group 222, and the magnetic polarity of the first magnetic group 13 facing the second magnetic group 212 is opposite to the magnetic polarity of the third magnetic group 222 facing the second magnetic group 212, so that the second magnetic group 212 can be magnetically connected to the first magnetic group 13 and the third magnetic group 222 at the same time. Specifically, the second magnetic group 212 is located between the first magnetic group 13 and the third magnetic group 222. A magnetic group 13 can be arranged on the bottom wall and / or side wall of the mounting groove 121, and can also be arranged on the outer bottom wall and / or outer side wall of the fixed body 12 facing away from the mounting groove 121. Part of the magnetic components of the second magnetic group 212 correspond to the first magnetic group 13 and are arranged on the surface of the transmitter body 211 facing the bottom wall of the mounting groove 121 and / or on the surface of the transmitter body 211 facing the side wall of the mounting groove 121. The third magnetic group 222 is arranged on the side of the sensor body facing the transmitter body 211, so that another part of the magnetic components of the second magnetic group 212 are correspondingly connected to the third magnetic group 222.

[0051] It can be understood that by setting the first magnetic group 13, the second magnetic group 212 and the third magnetic group 222, a quick detachable connection between the fixed body 12 and the detection component 2 as a whole, and a quick detachable connection between the transmitter module 21 and the sensor module 22 can be achieved. The blood glucose detection device 100 can be fixed to the user's skin surface using the fixing component 1, and there is no need to directly adhere the sensor module 22 to the user's skin surface, thereby avoiding the replacement of the sensor module 22 due to a decrease in adhesion, ensuring the continuous and stable operation of the sensor module 22, and reducing the use cost of the blood glucose detection device 100.

Specifically, the first magnetic group 13 can be arranged on the bottom wall and / or side wall of the mounting groove 121, and can also be arranged on the outer bottom wall and / or outer side wall of the fixed body 12 facing away from the mounting groove 121. Part of the magnetic parts of the second magnetic group 212 correspond to the first magnetic group 13 and are arranged on the surface of the transmitter body 211 facing the bottom wall of the mounting groove 121 and / or the surface of the transmitter body 211 facing the side wall of the mounting groove 121. The third magnetic group 222 is arranged on the side of the sensor body facing the transmitter body 211, so that another part of the magnetic parts of the second magnetic group 212 are correspondingly connected to the third magnetic group 222.
