[0042] Please refer to Figures 1 to 4As shown, the present application provides a blood glucose detection device 100, which comprises a fixing assembly 1 and a detection assembly 2, the fixing assembly 1 is provided with an adhesive tape 11, which is arranged to be attached to the skin of the user, and the detection assembly 2 is detachably connected to the fixing assembly 1, and the detection assembly 2 is provided with a detection surface 221, which is arranged to contact the skin of the user to detect the blood glucose level.

[0043] In this embodiment, the blood glucose detection device 100 is a medical device capable of monitoring the blood glucose level of the user, which can continuously and real-time monitor the daily blood glucose changes of the diabetic patient and record the blood glucose data in real time, and is widely used in the daily blood glucose management of diabetic patients. The blood glucose detection device 100 is attached to the skin to realize continuous blood glucose detection.

[0044] Specifically, as shown, Figure 1 The blood glucose detection device 100 comprises a fixing assembly 1 and a detection assembly 2, the fixing assembly 1 is usually attached to the skin of the human body, such as the upper arm or abdomen, and the detection assembly 2 is detachably connected to the fixing assembly 1, and a probe or detection electrode is arranged inside the detection assembly 2, and the probe or detection electrode is modified with glucose oxidase, so as to react with the glucose in the interstitial fluid through the glucose oxidase to realize the measurement of the glucose concentration in the interstitial fluid, and convert the detected glucose concentration into an electrical signal, and the blood glucose detection device 100 transmits the electrical signal about the glucose concentration obtained to an external signal receiving device, such as a smart phone, a smart watch, a special monitoring instrument, etc., so as to facilitate the user to view the data, analyze the data, and trace back the data, etc.

[0045] In this embodiment, the fixing assembly 1 is the main support structure of the blood glucose detection device 100, and the main structure of the fixing assembly 1 can be a plate structure, or a seat structure, or a table structure, or a shell structure, etc., which is not limited here, and the fixing assembly 1 is provided with an adhesive tape 11, which has an adhesive surface 111, which is directed to the side of the user's skin, and when the user wears the sensor, the adhesive surface 111 contacts and adheres to the user's skin.

[0046] At the same time, the detection assembly 2 is detachably connected to the fixing assembly 1, and when the detection assembly 2 is connected to the fixing assembly 1, the detection assembly 2 is limitingly connected to the fixing assembly 1, so that the detection surface 221 provided on the detection assembly 2 can abut to the skin of the user and detect the blood glucose level of the user.

[0047] It can be understood that by setting the detection assembly 2 and the fixing assembly 1 into a separable structure and fixing the skin of the user by the fixing assembly 1, the fixing assembly 1 can position and fix the detection assembly 2 on the skin surface of the user on the one hand, so as to ensure that the detection assembly 2 stably and continuously detects the blood glucose level of the user, and on the other hand, when the adhesion of the adhesive tape 11 of the fixing assembly 1 decreases, the fixing assembly 1 and the detection assembly 2 can be directly separated, and then a new fixing assembly 1 can be directly replaced without replacing the detection assembly 2, so that the replacement of the detection assembly 2 is reduced or avoided, thereby ensuring the continuous and stable work of the detection assembly 2 and effectively reducing the use cost of the blood glucose detection device 100.

[0048] The blood glucose detection device 100 of the technical solution comprises a fixing assembly 1 and a detection assembly 2, the fixing assembly 1 is provided with an adhesive tape 11, the adhesive tape 11 is arranged to adhere to the skin of the user, and the detection assembly 2 is separably connected to the fixing assembly 1, and the detection assembly 2 is provided with a detection surface 221 arranged to contact the skin of the user to detect the blood glucose level. By setting the detection assembly 2 for detecting the blood glucose level of the user and the fixing assembly 1 for adhering to the skin of the user into a separable structure, the positioning of the fixing assembly 1 to the detection assembly 2 and the adhesion of the fixing assembly 1 to the skin of the user can be realized at the same time on the basis of ensuring the blood glucose detection precision of the detection assembly 2, so that the adhesion of the detection assembly 2 to the skin of the user is not required, thereby avoiding the replacement of the detection assembly 2 due to the decrease of the adhesion, prolonging the service life of the detection assembly 2, ensuring the continuous work of the detection assembly 2, and reducing the use cost of the blood glucose detection device 100.

[0049] In an embodiment, as shown in Figures 1 to 4 The fixing assembly 1 comprises a fixing body 12 and an adhesive tape 11, and the adhesive tape 11 is arranged at the periphery of the fixing body 12; and the detection assembly 2 is separably connected to the fixing body 12, and the adhesive tape 11 is arranged around the detection assembly 2.

[0050] In the embodiment, the fixing body 12 is the main support structure of the fixing assembly 1 and the blood glucose detection device 100, and the fixing body 12 can be a plate body, a frame body, a shell body, a groove body, a rack body, a table body or the like, and the adhesive tape 11 is arranged at the periphery of the fixing body 12, for example, the periphery of the fixing body 12 is provided with a protruding adhesion part, one side of the adhesive tape 11 is adhered to the adhesion part, and the other side of the adhesive tape 11 away from the adhesion part is adhered to the skin of the user.

[0051] Meanwhile, the detection assembly 2 is separably connected to the fixing body 12, for example, by magnetic connection, buckle connection, slot insertion connection, screw connection or the like, and the adhesive tape 11 is arranged around the detection assembly 2.

[0052] It can be understood that by setting the detection assembly 2 and the fixed body 12 in separable connection, when the adhesion of the adhesive tape 11 is insufficient to make the detection assembly 2 adhere to the skin of the user for blood glucose detection, the fixed body 12 can be separated, disassembled and replaced alone, and the detection assembly 2 is retained, so as to reduce or even avoid the replacement of the detection assembly 2, thereby ensuring the continuous and stable work of the detection assembly 2 and effectively reducing the use cost of the blood glucose detection device 100.

[0053] In addition, the adhesive tape 11 is arranged around the detection assembly 2, and preferably the periphery of the adhesive tape 11 adhered to the fixed body 12 is circular, so that the detection assembly 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 the detection assembly 2 are consistent, and the detection surface 221 of the detection assembly 2 can abut the skin surface of the user at each position, so as to ensure the accuracy and stability of the blood glucose detection of the detection assembly 2.

[0054] In an embodiment, as shown in Figure 2 and Figure 3 , the fixed body 12 is provided with a mounting groove 121, and the adhesive tape 11 is arranged at the periphery of the groove opening of the mounting groove 121; and the detection assembly 2 is limited in the mounting groove 121.

[0055] It can be understood that the fixed body 12 is a housing or a table body structure, and the mounting groove 121 is arranged on the fixed body 12, preferably, the cross section of the groove body of the mounting groove 121 is circular, and the adhesive tape 11 is arranged at the periphery of the groove opening of the mounting groove 121, and the detection assembly 2 is separably arranged in the mounting groove 121 and can be separated from the fixed body 12 at the groove opening of the mounting groove 121, and the abutting surface 2111 is arranged on the side of the detection assembly 2 away from the detection surface 221, and the abutting surface 2111 can be limited and abut at least part of the bottom wall of the mounting groove 121 and can also be limited and abut the side wall of the mounting groove 121. First, by the cooperation of the mounting groove 121 and the adhesive tape 11, the detection assembly 2 is limited in the direction perpendicular to the detection surface 221, so that the detection surface 221 of the detection assembly 2 abuts the skin of the user, and at the same time, the side wall of the mounting groove 121 can also limit the detection assembly 2 in the direction parallel to the detection surface 221, so as to prevent the detection assembly 2 from translating in the direction of the detection surface 221, thereby improving the limiting and positioning ability of the fixed body 12 and the mounting groove 121 on the detection assembly 2, and ensuring the stability and accuracy of the blood glucose level detection of the detection assembly 2.

[0056] In an embodiment, as shown in Figure 2 and Figure 3As shown, the detection assembly 2 is magnetically connected to the bottom wall of the at least partial mounting groove 121, and optionally, the detection assembly 2 is magnetically connected to the side wall of the at least partial mounting groove 121. It can be understood that the detection assembly 2 and the fixed main body 12 are magnetically connected through the magnetic member, such as the detection assembly 2 is magnetically connected to the bottom wall of the at least partial mounting groove 121, or the detection assembly 2 is magnetically connected to the side wall of the mounting groove 121, so as to improve the separability between the detection assembly 2 and the fixed main body 12, and to realize the quick separation and installation between the detection assembly 2 and the fixed main body 12, and to improve the convenience of use, and to facilitate the one-handed operation.

[0057] 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 can be understood that the detection surface 221 protrudes from the slot 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. Therefore, when the adhesive surface 111 of the adhesive tape 11 is adhered to the skin of the user, the detection surface 221 first contacts the skin of the user, and the detection assembly 2 can compress the skin in contact with the detection surface 221, so that the detection surface 221 abuts against the skin of the user, improves the contact between the probe or the detection electrode provided on the detection surface 221 of the detection assembly 2 and the skin of the user, and ensures the accuracy and stability of the detection assembly 2 when measuring the blood glucose level.

[0059] It can be understood that the main structure of the detection assembly 2 is provided in a circular structure, such as the outer shell of the detection assembly 2 is provided in a cylindrical structure, and the first screw thread is provided on the outside of the detection assembly 2. The mounting groove 121 is correspondingly provided in a circular groove, and the second screw thread is provided on the inner wall of the mounting groove 121. The first screw thread and the second screw thread are screw-connected, so as to realize the quick separable connection between the detection assembly 2 and the fixed main body 12. Through the connection of the first screw thread and the second screw thread, the fixed main body 12 can limit and fix the detection assembly 2 in the direction perpendicular to the detection surface 221 and in the direction parallel to the detection surface 221, so as to ensure the determination of the position of the detection assembly 2 and the fixation of the contact position between the detection surface 221 and the skin when the fixed main body 12 is adhered to the skin of the user, and to improve the detection accuracy and stability.

[0060] In an embodiment, the fixed assembly 1 further comprises a limiting protrusion, and the limiting protrusion is provided 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.

[0061] It can be understood that the limiting protrusion is arranged on the inner wall of the mounting groove 121, and the side of the limiting protrusion away from the inner wall of the mounting groove 121 is provided with a guide surface, the guide surface is arranged at an angle with 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 slot of the mounting groove 121 to the bottom wall of the mounting groove 121, so that when the detection assembly 2 extends into the mounting groove 121, the main body structure of the detection assembly 2 can gradually abut against the limiting protrusion, to ensure the fixation of the position of the detection assembly 2 in the mounting groove 121, avoid displacement of the detection assembly 2 in the direction parallel to the detection surface 221, and improve the detection accuracy and stability.

[0064] It can be understood that the transmitter module 21 and the sensor module 22 are separately connected, so that the sensor module 22 can be replaced alone after the glucose oxidase in the sensor module 22 is exhausted, without the need to replace or discard the transmitter module 21 together, on the one hand, to improve the overall use convenience of the detection assembly 2, and facilitate separate disassembly for maintenance, cleaning and repair, on the other hand, to continue to use the transmitter module 21, and further reduce the use cost.

On the other hand, it also provides installation space for the first magnetic group 13 and the second magnetic group 212, reduces the distance between the first magnetic group 13 and the second magnetic group 212, and improves the magnetic connection force between the first magnetic group 13 and the second magnetic group 212, so as to ensure the connection strength between the transmitter module 21 and the fixed body 12. At the same time, it is also convenient to install and place the first magnetic group 13 on the fixed body 12, and to install and place the second magnetic group 212 on the transmitter body 211.

[0075] In one embodiment, such as Figures 2 to 4 As shown, the transmitter module 21 includes a transmitter body 211 and a second magnetic group 212. The transmitter body 211 is provided with a second limiting groove 2113, and the second magnetic group 212 is provided in the second limiting groove 2113. The sensor module 22 is provided with a second guide post 223, which is limited in the second limiting groove 2113, and the third magnetic group 222 is provided in the second guide post 223.

[0076] In this embodiment, the sensor module 22 includes a sensor body and a second magnetic group 212. The second magnetic group 212 is disposed on the sensor body. Specifically, the sensor body is provided with a second guide post 223. The second guide post 223 is disposed on the bottom wall of the mounting groove 121 and extends along the groove depth direction of the mounting groove 121. The second guide post 223 can be a solid structure or a thin shell structure with guide holes opened along the extension direction of the main body of the guide post. The transmitter body 211 is provided with a second limiting groove 2113. The second guide post 223 is limited in the second limiting groove 2113 to limit and fix the transmitter module 21 as a whole on the sensor body. The sensor body includes a plurality of second guide posts 223. The plurality of second guide posts 223 are disposed in parallel and spaced apart on the bottom wall of the mounting groove 121. The transmitter body 211 is provided with a plurality of second limiting grooves 2113 corresponding to the plurality of second guide posts 223, so that each guide post is limited in a second limiting groove 2113.

[0077] Further, when the second guide pillar 223 is a solid structure, the third magnetic group 222 can be arranged on the side of the second guide pillar 223 facing the second limiting groove 2113 and / or the side wall of the second guide pillar 223, and when the second guide pillar 223 is a thin shell structure with a guide hole, the third magnetic group 222 can be arranged on the side of the second guide pillar 223 facing the second limiting groove 2113, or on the side of the second guide pillar 223 away from the second limiting groove 2113 and / or the side wall of the second guide pillar 223, which is not limited herein. At the same time, at least part of the second magnetic group 212 can be arranged on the bottom wall and / or the side wall of the second limiting groove 2113.

[0078] It can be understood that by arranging the second guide pillar 223 and the second limiting groove 2113, and extending the second guide pillar 223 into and limiting it in the second limiting groove 2113, on the one hand, the transmitter module 21 can be limited and installed on the sensor main body, ensuring the position fixation between the transmitter module 21 and the detection assembly 2 relative to the sensor main body, and on the other hand, providing installation space for the third magnetic group 222 and the second magnetic group 212, reducing the distance between the third magnetic group 222 and the second magnetic group 212, improving the magnetic connection force between the third magnetic group 222 and the second magnetic group 212, to ensure the connection strength between the transmitter module 21 and the sensor main body, and at the same time, facilitating the installation and placement of the third magnetic group 222 on the sensor main body, and facilitating the installation and placement of the second magnetic group 212 on the transmitter main body 211.

[0079] In an embodiment, the magnetic connection force between the third magnetic group 222 and the second magnetic group 212 is greater than the magnetic connection force between the second magnetic group 212 and the first magnetic group 13.

[0080] In the embodiment, the third magnetic group 222 is magnetically connected with the second magnetic group 212 to separably connect the sensor module 22 and the transmitter module 21, the second magnetic group 212 is magnetically connected with the first magnetic group 13 to separably connect the transmitter module 21 and the fixed body 12, and the whole detection assembly 2 is separably connected with the fixed body 12. The magnetic connection force between the third magnetic group 222 and the second magnetic group 212 is set to be greater than the magnetic connection force between the second magnetic group 212 and the first magnetic group 13, so that the magnetic connection force between the sensor module 22 and the transmitter module 21 is greater than the magnetic connection force between the transmitter module 21 and the fixed body 12. Specifically, in the case that the sizes and volumes of the first magnetic group 13, the second magnetic group 212 and the third magnetic group 222 are the same, the material of the magnetic part in the third magnetic group 222 is set to be a rare earth permanent magnet, and the material of the magnetic part in the first magnetic group 13 is set to be a ferrite permanent magnet, so that the magnetic connection force between the third magnetic group 222 and the second magnetic group 212 is greater than the magnetic connection force between the second magnetic group 212 and the first magnetic group 13. Or in the case that the materials of the first magnetic group 13, the second magnetic group 212 and the third magnetic group 222 are the same, the magnetic connection area between the third magnetic group 222 and the second magnetic group 212 is greater than the magnetic connection area between the first magnetic group 13 and the second magnetic group 212, so that the magnetic connection force between the third magnetic group 222 and the second magnetic group 212 is greater than the magnetic connection force between the second magnetic group 212 and the first magnetic group 13, which is not limited herein.

[0081] It can be understood that by making the magnetic connection force between the sensor module 22 and the transmitter module 21 greater than the magnetic connection force between the transmitter module 21 and the fixed body 12, when the fixed body 12 is separated, disassembled and replaced, the sensor module 22 and the transmitter module 21 can be quickly and easily separated from the fixed body 12 as a whole detection assembly 2, thereby improving the separability of the detection assembly 2 and the fixed body 12.
