[0024] Please refer to Figures 1 to 7As shown, the present invention proposes a blood glucose detection device 100, which includes a sensor 1 and a transmitter 2. The sensor 1 includes a sensor body 11 and at least one first connecting member 13. The transmitter 2 includes a transmitter body 21 and at least one second connecting member 22. The transmitter body 21 is provided with a mounting groove 211. Each second connecting member 22 is arranged on the groove wall of the mounting groove 211. The second connecting member 22 and the bottom wall of the mounting groove 211 are enclosed to form a limiting groove 212. The blood glucose detection device 100 has a separation state in which the sensor 1 and the transmitter 2 are separated from each other and an assembly state in which the sensor 1 and the transmitter 2 are connected to each other. In the separation state, each first connecting member 13 is located in the mounting groove 211. In the assembly state, the sensor body 11 is rotatably connected to the transmitter body 21, and each first connecting member 13 is limited to abut a second connecting member 22 and is limited in the limiting groove 212.

[0025] 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 the daily blood glucose management of diabetic patients. The blood glucose detection device 100 of this application is attached to the skin to achieve continuous blood glucose detection.

[0026] Specifically, the blood glucose detection device 100 includes a sensor 1 and a transmitter 2. The sensor 1 is usually attached to the human skin, such as the upper arm or abdomen, and a probe or detection electrode is arranged inside the sensor 1. The probe or the detection electrode is modified with glucose oxidase so that the glucose oxidase reacts with the 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 transmitter 2 is electrically connected to the sensor 1 to obtain the electrical signal about the glucose concentration in the sensor 1, and at the same time, the obtained blood glucose 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, analyze, and trace back data.

[0027] At the same time, if Figures 2 to 7 As shown, the sensor 1 and the transmitter 2 are detachably connected. By setting the sensor 1 and the transmitter 2 as a detachable structure, when the connection between the sensor 1 and the user fails or the glucose oxidase inside the sensor 1 is exhausted, the sensor 1 can be replaced alone and the transmitter 2 can be retained. There is no need to replace or discard the transmitter 2 together. On the one hand, the overall ease of use of the blood glucose detection device 100 is improved, and it is convenient to disassemble them separately for maintenance, cleaning and repair. On the other hand, the transmitter 2 can continue to be used, further reducing the cost of use.

The sensor body 11 is the main supporting structure of the sensor 1, which can be a plate-shaped, sheet-shaped, shell, table, column and other structures, and the sensor body 11 can also be a flexible structure, so that the sensor 1 can contact and fit the user's skin.

Similarly, the transmitter 2 includes a transmitter body 21 and at least one first connecting member 13. The transmitter body 21 is the main supporting structure of the transmitter 2, which can be a plate-shaped, sheet-shaped, shell, table, column and other structures, and the transmitter body 21 can also be a flexible structure, so that the transmitter 2 can contact and fit the user's skin. The first connecting member 13 is a protruding structure or a limiting block structure, and the first connecting member 13 is arranged on the transmitter body 21.

[0029] Furthermore, the sensor 1 also includes a first conductive member, which is arranged on the first connecting member 13; the transmitter 2 also includes a second conductive member, which is arranged on the limiting groove 212; in the assembled state, the first conductive member abuts and conducts the second conductive member to achieve electrical connection between the sensor 1 and the transmitter 2, and transmits the electrical signal detected by the sensor 1 to the transmitter 2 through the first conductive member and the second conductive member.

[0030] In this embodiment, if Figure 4 and Figure 7 As shown, the transmitter body 21 is provided with a mounting groove 211, and the mounting groove 211 can be a circular ring groove arranged around the transmitter body 21, or a sunken groove arranged on the transmitter body 21, so that the second connecting member 22 is arranged on the groove wall of the mounting groove 211. At the same time, the second connecting member 22 and the bottom wall of the mounting groove 211 are enclosed to form a limiting groove 212, and the first connecting member 13 arranged on the sensor body 11 can extend into the mounting groove 211 and can be limited in the limiting groove 212.

[0031] It can be understood that the blood glucose detection device 100 has a separation state and an assembly state. In the separation state, the sensor 1 and the transmitter 2 are separated from each other, or are rotationally connected to each other but not electrically connected to each other, such as only the first connecting member 13 is arranged in the installation groove 211; in the assembly state, the transmitter body 21 and the sensor body 11 are rotationally connected, and each first connecting member 13 is limited to abut against a second connecting member 22, and the first connecting member 13 is limited in the limiting groove 212.

[0032] Of course, the installation groove 211 can also be provided on the sensor body 11, and a limiting groove 212 can be formed on the sensor body 11 by enclosing the first connecting member 13 and the bottom wall of the installation groove 211, so that in the assembled state, the second connecting member 22 is limited to abut against the first connecting member 13 and is limited in the limiting groove 212.

[0033] It can be understood that the transmitter body 21 and the sensor body 11 can be a cylindrical structure or a columnar structure, and a mounting groove 211 is formed at the end of the transmitter body 21 to install the second connecting member 22, and a first connecting member 13 is arranged at the end of the sensor body 11, so that the first connecting member 13 of the sensor body 11 can be inserted into the mounting groove 211, and the transmitter body 21 and the sensor body 11 are rotatably connected so that the first connecting member 13 and the second connecting member 22 are limitedly abutted, or a rotating shaft 12 is arranged on the transmitter body 21 or the sensor body 11, so that the first connecting member 13 or the second connecting member 22 is arranged on the rotating shaft 12, and in the separated state, the rotating shaft 12 extends into the mounting groove 211, and in the assembled state, the rotating shaft 12 rotates relative to the mounting groove 211, and the first connecting member 13 and the second connecting member 22 are limitedly abutted, and at the same time limited in the limiting groove 212, which is not limited here.

[0034] It can be understood that by setting the transmitter 2 and the sensor 1 as a separable structure, and setting the transmitter body 21 and the sensor body 11 as a rotational connection, the position of the first connecting member 13 can be changed by the relative rotation of the transmitter body 21 and the sensor body 11, and in the assembled state, the first connecting member 13 is limited to abut against the second connecting member 22, and is limited in the limiting groove 212 to achieve fixation between the transmitter 2 and the sensor 1. The technical solution of the present application does not require the additional arrangement of an elastic unlocking mechanism and a corresponding snap fastener, etc., and fixation and separation can be achieved only by aligning and connecting the transmitter 2 and the sensor 1 and rotating them, which effectively simplifies the connection structure of the transmitter 2 and the sensor 1 and improves ease of use.

[0035] The blood glucose detection device 100 of the technical solution of the present invention comprises a sensor 1 and a transmitter 2, wherein the sensor 1 comprises a sensor body 11 and at least one first connecting member 13, and the transmitter 2 comprises a transmitter body 21 and at least one second connecting member 22, wherein the transmitter body 21 is provided with a mounting groove 211, wherein each second connecting member 22 is arranged on the groove wall of the mounting groove 211, and the second connecting member 22 and the bottom wall of the mounting groove 211 are enclosed to form a limiting groove 212; the blood glucose detection device 100 has a separated state and an assembled state, wherein in the separated state, each first connecting member 13 is located in the mounting groove 211; and in the assembled state, The sensor body 11 is rotatably connected to the transmitter body 21, and each first connecting member 13 is limitedly abutted against a second connecting member 22 and is limited in the limiting groove 212. The sensor body 11 and the transmitter body 21 are set to be rotatably connected to change the position of the first connecting member 13 relative to the second connecting member 22, that is, the first connecting member 13 and the second connecting member 22 are limitedly abutted against each other by rotation, thereby realizing a detachable connection between the transmitter 2 and the sensor 1, effectively simplifying the connection structure of the sensor 1 and the transmitter 2, improving the convenience of use, and improving the structural compactness of the blood glucose detection device 100.

[0036] In one embodiment, if Figure 3 , Figure 6 as well as Figure 7 As shown, the transmitter 2 includes a plurality of second connecting members 22, and two adjacent second connecting members 22 enclose a guide groove 213, which connects the notch of the mounting groove 211 and the limiting groove 212; the sensor 1 includes a plurality of first connecting members 13, and in a separated state, each first connecting member 13 is limited to a guide groove 213.

[0037] In this embodiment, the transmitter 2 includes a plurality of second connecting members 22, and the mounting groove 211 is a circular recessed groove, so that each second connecting member 22 is evenly spaced on the groove wall of the mounting groove 211, and a guide groove 213 is formed between each adjacent two second connecting members 22, and the groove body of the guide groove 213 extends roughly along the groove depth direction of the mounting groove 211, and one end of the guide groove 213 is connected to the groove opening of the mounting groove 211, and the other end of the guide groove 213 is connected to the limit groove 212. At the same time, the sensor 1 also includes a plurality of first connecting members 13, and the plurality of first connecting members 13 can be directly and evenly spaced on the sensor body 11, or can be evenly spaced on the rotating shaft 12 of the sensor 1, which is not limited here.

[0038] It can be understood that, in the separated state, each first connecting member 13 is limited to extend into a guide groove 213, and extends into the limiting groove 212 along the groove extension direction of the guide groove 213, and in the assembled state, the sensor body 11 rotates relative to the transmitter body 21, and the multiple first connecting members 13 extending into the limiting groove 212 move along the limiting groove 212, and each first connecting member 13 is limited to abut against a second connecting member 22, so that the multiple first connecting members 13 are limited in the limiting groove 212, so that in the assembled state, the position between the sensor 1 and the transmitter 2 is kept fixed, the connection stability between the sensor 1 and the transmitter 2 is improved, and the circuit conduction and communication connection between the sensor 1 and the transmitter 2 are kept stable, so that the overall blood glucose detection device 100 can work stably.

[0039] In one embodiment, if Figure 7 As shown, the guide groove 213 extends along the groove depth direction of the installation groove 211 ; optionally, the guide groove 213 extends along a direction forming an angle with the groove depth direction of the installation groove 211 .

[0040] It can be understood that the groove body extension direction of the guide groove 213 can be consistent with the groove depth direction of the mounting groove 211, or it can extend at an angle to the groove depth direction of the mounting groove 211, that is, the groove body of the guide groove 213 can be a straight groove, or it can be a spiral groove surrounding the side wall of the mounting groove 211, which is not limited here. The first connecting member 13 can extend into the guide groove 213 and enter the limiting groove 212 along the guide groove 213, wherein the guide groove 213 is set as a straight groove extending along the groove depth direction of the mounting groove 211, which is convenient for users to directly align and connect the sensor 1 and the transmitter. The emitter 2 is provided with a guide groove 213 to directly limit the first connecting member 13 in the guide groove 213, and the straight groove-shaped guide groove 213 can also reduce the groove depth of the installation groove 211, thereby reducing the volume occupied by the emitter 2 and the sensor 1 for setting the first connecting member 13 and the second connecting member 22, and effectively simplifying the overall structure; the guide groove 213 set as a spiral groove can self-lock and limit the first connecting member 13 through the spiral structure to ensure the stability of the connection between the emitter 2 and the sensor 1, and ensure stable circuit conduction and communication connectivity between the two in the assembled state.

[0041] In one embodiment, if Figure 4 and Figure 7 As shown, the second connecting member 22 is provided with a notch portion 221, and the notch portion 221 is located at the connection between the guide groove 213 and the limiting groove 212; optionally, the second connecting member 22 is provided with a notch portion 221, and the notch portion 221 is located at the connection between the guide groove 213 and the notch of the installation groove 211.

[0042] In this embodiment, a notch portion 221 is provided at at least one end of the second connecting member 22 along the groove extension direction of the guide groove 213. The notch portion 221 is a notch groove structure, and the shape of the notch groove is not limited. It can be a triangular, curved or other special-shaped groove, so that the notch portion 221 located at the connection between the guide groove 213 and the limiting groove 212 can simultaneously connect the guide groove 213 and the limiting groove 212, and / or the notch portion 221 located at the connection between the guide groove 213 and the groove opening of the installation groove 211 can simultaneously connect the guide groove 213 and the external space.

[0043] It can be understood that by providing the notch portion 221, the groove width of the guide groove 213 at the connection point with the limiting groove 212 and / or the connection point between the guide groove 213 and the slot opening of the mounting groove 211 (that is, the connection point with the external space) can be expanded, so as to improve the smoothness of the first connecting member 13 entering the guide groove 213 from the connection point between the guide groove 213 and the slot opening of the mounting groove 211, and improve the fault tolerance of the first connecting member 13 entering the guide groove 213; and improve the smoothness of the first connecting member 13 entering the limiting groove 212 from the guide groove 213, and improve the fault tolerance of the first connecting member 13 entering the limiting groove 212, thereby reducing interference between structures, facilitating user use, and improving ease of use.

[0044] In one embodiment, the distance between the second connecting member 22 and the bottom wall of the installation groove 211 is gradually reduced along the groove wall of the installation groove 211 .

[0045] It can be understood that the distance between the second connecting member 22 and the bottom wall of the installation groove 211, that is, the groove width of the limiting groove 212 gradually changes and gradually decreases along the groove wall of the installation groove 211. When the sensor body 11 and the transmitter body 21 rotate relative to each other and the first connecting member 13 rotates along the limiting groove 212, the first connecting member 13 gradually presses against the groove wall of the limiting groove 212, and the limiting groove 212 locks the first connecting member 13, so that the connection and installation of the transmitter 2 and the sensor 1 are more linear and smooth. At the same time, it can also ensure the locking effect between the sensor 1 and the transmitter 2, and ensure the stability of the connection between the two.

[0046] In one embodiment, the transmitter 2 further includes a limiting protrusion, which is disposed in the limiting groove 212 ; the limiting protrusion is located between the second connecting member 22 and the bottom wall of the installation groove 211 .

[0047] In this embodiment, the limiting protrusion protrudes from the side wall of the limiting groove 212 toward the side wall away from the limiting groove 212, and the limiting protrusion is arranged between the second connecting member 22 and the bottom wall of the installation groove 211, and the limiting protrusion can be connected to the second connecting member 22, or it can be spaced apart from the second connecting member 22, and the limiting protrusion is smoothly transitionally connected to the groove wall of the limiting groove 212.

[0048] It can be understood that a limiting protrusion is provided on the side wall of the limiting groove 212, so that when the first connecting member 13 moves along the limiting groove 212, the limiting protrusion can limit and fix the first connecting member 13, thereby preventing the first connecting member 13 from detaching from the limiting groove 212 due to a small external force and sliding out of the guide groove 213, which will cause the transmitter 2 and the sensor 1 to separate, so as to effectively enhance the clamping force and connection stability between the first connecting member 13 and the limiting groove 212, increase the locking effect of the first connecting member 13 and the limiting groove 212, and ensure the locking effect and connection stability of the transmitter 2 and the sensor 1.

[0049] In one embodiment, if Figures 1 to 3 as well as Figures 5 to 7 As shown, the sensor 1 also includes a first limit member 14, and the first limit member 14 and the first connecting member 13 are spaced apart in the sensor body 11; the transmitter 2 also includes a second limit member 23, and the second limit member 23 and the mounting groove 211 are spaced apart in the transmitter body 21. In the assembled state, the first limit member 14 is limited and abuts against the second limit member 23.

[0050] In this embodiment, the first limiting member 14 and the second limiting member 23 can be a protruding structure or an elastic structure, wherein the first limiting member 14 and the first connecting member 13 are spaced apart on the sensor body 11, and the second limiting member 23 and the mounting groove 211 are spaced apart on the transmitter body 21, so that when the first connecting member 13 extends into the mounting groove 211 and abuts against the second connecting member 22, the first limiting member 14 and the second limiting member 23 also abut against each other and limit each other, such as setting a first inclined portion on one side of the first limiting member 14. A second inclined surface is provided on one side of the second limit member 23, and the mutual limiting abutment of the first limit member 14 and the second limit member 23 is achieved through the mutual abutment of the first inclined surface and the second inclined surface, or one of the first limit member 14 and the second limit member 23 is a marble structure, and the other of the first limit member 14 and the second limit member 23 is provided with a groove. When the first limit member 14 abuts against the second limit member 23, the marble structure can be limited in the groove to achieve the mutual limiting abutment of the first limit member 14 and the second limit member 23.

[0051] It can be understood that through the limiting abutment of the first limiting member 14 and the second limiting member 23, the transmitter body 21 and the sensor body 11 can be further limited to ensure the accuracy and fixity of the relative positions of the sensor body 11 and the transmitter body 21 in the assembled state, thereby ensuring stable circuit conduction and signal conduction between the sensor 1 and the transmitter 2, ensuring the normal and continuous operation of the blood glucose detection device 100, and improving the stability and continuity of blood glucose detection.

[0052] In one embodiment, if Figures 1 to 3 as well as Figures 5 to 7As shown, the first limiting member 14 and the second limiting member 23 are located on the same side of the blood glucose detection device 100; optionally, as Figure 3 , Figure 5 as well as Figure 6 As shown, the sensor body 11 is provided with a first give way groove 111, the first limit member 14 is elastically connected to the bottom wall of the first give way groove 111, and the first limit member 14 and the side wall of the first give way groove 111 are spaced apart; it can be understood that the first limit member 14 is arranged in the first give way groove 111 and is elastically connected to the bottom wall of the first give way groove 111, so that when the second limit member 23 abuts against the first limit member 14, the first limit member 14 can be elastically deformed to make the first limit member 14 and the second limit member 23 reach the position of limited abutment and fix the relative positions between the two, and part of the second limit member 23 can extend into the first give way groove 111 to reduce the space occupied by the first limit member 14 and the second limit member 23, thereby improving the structural compactness of the overall blood glucose detection device 100.

[0053] Alternatively, if Figure 5 and Figure 7 As shown, the transmitter body 21 is provided with a second clearance groove 214, and the second limiting member 23 is provided on the bottom wall of the second clearance groove 214; it can be understood that by providing the second clearance groove 214, part of the first limiting member 14 can be extended into the second clearance groove 214, so as to reduce the space occupied by the first limiting member 14 and the second limiting member 23, and improve the structural compactness of the overall blood glucose detection device 100.

[0054] In one embodiment, if Figure 5 and Figure 6 As shown, the sensor body 11 is provided with a mounting surface 112 facing the transmitter body 21, and the first limiting member 14 is provided with a first side surface 141 and a second side surface 142 connected to each other, and the first side surface 141 and the second side surface 142 are arranged to be opposite to each other; the angle between the first side surface 141 and the mounting surface 112 is greater than the angle between the second side surface 142 and the mounting surface 112.

[0055] In the present embodiment, the sensor body 11 is a plate-like or sheet-like structure so that the sensor 1 can be fitted onto the user's skin as a whole. A mounting surface 112 is provided on the side of the sensor body 11 facing the transmitter body 21, so that the first limiting member 14 provided on the sensor body 11 partially protrudes from the mounting surface 112 to limit and abut against the second limiting member 23. A first side surface 141 and a second side surface 142 connected to each other are provided on the first limiting member 14. The first side surface 141 and the second side surface 142 are arranged at an angle and are arranged away from each other. In a separated state, the first side surface 141 abuts against the second limiting member 23. In an assembled state, the sensor body 11 rotates relative to the transmitter body 21. The first limiting member 14 causes the first side surface 141 to gradually break away from the abutment with the second limiting member 23 through elastic deformation, and limits and abuts against the second limiting member 23 through the second side surface 142, so as to achieve the limiting abutment between the first limiting member 14 and the second limiting member 23.

[0056] At the same time, the angle between the first side surface 141 and the mounting surface 112 is greater than the angle between the second side surface 142 and the mounting surface 112, such as the angle between the second side surface 142 and the mounting surface 112 is less than or equal to 45 degrees and greater than or equal to 30 degrees, and the angle between the first side surface 141 and the mounting surface 112 is less than or equal to 70 degrees and greater than or equal to 45 degrees, which is not limited here, wherein the angle between the second side surface 142 and the mounting surface 112 is the entry angle of the first contact between the second stopper 23 and the first stopper 14, and the angle between the first side surface 141 and the mounting surface 112 is the exit angle of the second stopper 23 and the first stopper 14 from contacting, and the entry angle A smaller angle is more conducive to the mutual abutment between the second limit member 23 and the first limit member 14, and to push the first limit member 14 to elastically deform so as to achieve the abutment between the second limit member 23 and the second side surface 142, so as to facilitate the assembly and connection between the sensor body 11 and the transmitter body 21. A larger exit angle can also enhance the limiting abutment effect of the first limit member 14 and the second limit member 23, and avoid the detachment of the first limit member 14 and the second limit member 23 due to misoperation, so as to ensure the stability of the connection between the transmitter 2 and the sensor 1, and ensure the normal and continuous operation of the blood glucose detection device 100, so as to improve the stability and continuity of blood glucose detection.

[0057] In one embodiment, if Figures 1 to 4 as well as Figure 6 and Figure 7 As shown, the transmitter body 21 is further provided with a guide groove 215 ; the sensor 1 further comprises a guide member 15 , which is spaced apart from the first connecting member 13 at both ends of the sensor body 11 ; in the assembled state, the guide member 15 is limited in the guide groove 215 .

[0058] In this embodiment, the guide groove 215 is provided on the transmitter body 21, the guide groove 215 and the mounting groove 211 are spaced apart at both ends of the transmitter body 21, the guide member 15 is provided on the sensor body 11, and the guide member 15 and the first connecting member 13 are spaced apart at both ends of the sensor body 11, so that in the assembled state, when the first connecting member 13 is limited in the mounting groove 211, the guide member 15 is limited in the guide groove 215.

[0059] At the same time, the guide groove 215 is preferably an arc groove, and the center of curvature of the arc groove is the groove center of the mounting groove 211, so that when the transmitter body 21 and the sensor body 11 rotate relative to each other, the guide member 15 can extend into the guide groove 215 along the rotation direction, wherein the guide groove 215 is not limited to being provided in the transmitter body 21, and the guide member 15 is not limited to being provided in the sensor body 11. For example, the guide groove 215 is provided in the sensor body 11, and the guide member 15 is provided in the transmitter body 21, which is not limited here.

[0060] It can be understood that by setting the guide groove 215 and the guide member 15, the transmitter body 21 and the sensor body 11 can be further limited to ensure the accuracy and fixity of the relative positions of the sensor body 11 and the transmitter body 21 in the assembled state, thereby ensuring stable circuit conduction and signal conduction between the sensor 1 and the transmitter 2, ensuring the normal and continuous operation of the blood glucose detection device 100, and improving the stability and continuity of blood glucose detection.

[0061] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
