[0057] In an embodiment, as shown in Figure 3 、 Figure 6 and Figure 7 , the transmitter 2 includes a plurality of second connecting pieces 22, and adjacent two second connecting pieces 22 form a guide groove 213, and the guide groove 213 is communicated with the slot opening of the mounting groove 211 and the limiting groove 212; the sensor 1 includes a plurality of first connecting pieces 13, and in the separated state, each first connecting piece 13 is limited in a guide groove 213.

[0058] In the embodiment, the transmitter 2 comprises a plurality of second connecting members 22, the mounting groove 211 is a circular recess, each second connecting member 22 is uniformly arranged on the groove wall of the mounting groove 211, each adjacent two second connecting members 22 enclose a guide groove 213, the groove body of the guide groove 213 extends along the groove depth direction of the mounting groove 211, one end of the guide groove 213 communicates with the groove opening of the mounting groove 211, the other end of the guide groove 213 communicates with the limiting groove 212, and the sensor 1 also comprises a plurality of first connecting members 13, which are directly and uniformly arranged on the sensor body 11 or the rotating shaft 12 of the sensor 1, which is not limited here.

[0059] It can be understood that in the separated state, each first connecting member 13 is limited to extend into a guide groove 213 and extend into a limiting groove 212 along the groove body extension direction of the guide groove 213, and in the assembled state, the sensor body 11 rotates relative to the transmitter body 21, the plurality of 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 plurality of first connecting members 13 are limited in the limiting groove 212, thereby maintaining the position between the sensor 1 and the transmitter 2 in the assembled state, improving the connection stability of the sensor 1 and the transmitter 2, and maintaining the stability of the circuit conduction and communication connection between the sensor 1 and the transmitter 2, so that the overall blood glucose detection device 100 works stably.

[0060] In an embodiment, as shown in Figure 7 the guide groove 213 extends along the groove depth direction of the mounting groove 211; alternatively, the guide groove 213 extends along a direction that forms an angle with the groove depth direction of the mounting groove 211.

[0061] It can be understood that the slot body extension direction of the guide groove 213 can be consistent with the groove depth direction of the mounting groove 211, or can extend at an angle with the groove depth direction of the mounting groove 211, that is, the slot body of the guide groove 213 can be a straight groove, or a spiral groove around the side wall of the mounting groove 211, which is not limited here. The first connecting piece 13 can extend into the guide groove 213 and enter the limiting groove 212 along the guide groove 213. Among them, the guide groove 213 is provided as a straight groove extending along the groove depth direction of the mounting groove 211, which facilitates the user to directly align and connect the sensor 1 and the transmitter 2, so as to directly limit the first connecting piece 13 in the guide groove 213, and the straight groove-shaped guide groove 213 can also reduce the groove depth of the mounting groove 211, thereby reducing the volume occupation of the transmitter 2 and the sensor 1 for setting the first connecting piece 13 and the second connecting piece 22, effectively simplifying the overall structure; the guide groove 213 provided as a spiral groove can self-lock and limit the first connecting piece 13 through the spiral structure, so as to ensure the stability of the connection between the transmitter 2 and the sensor 1, and ensure the stable circuit conduction and communication connection of the two in the assembled state.

[0062] In an embodiment, as shown in Figure 4 and Figure 7 The second connecting piece 22 is provided with a notch portion 221 located at the communication position of the guide groove 213 and the limiting groove 212; optionally, the second connecting piece 22 is provided with a notch portion 221 located at the communication position of the guide groove 213 and the slot opening of the mounting groove 211.

[0063] In the embodiment, the second connecting piece 22 is provided with a notch portion 221 at at least one end along the slot body extension direction of the guide groove 213, and the notch portion 221 is a notch groove structure, and is not limited to the shape of the notch groove, which can be a triangular, arc-shaped or other special-shaped groove, so that the notch portion 221 located at the communication position of the guide groove 213 and the limiting groove 212 can simultaneously communicate the guide groove 213 and the limiting groove 212, and / or the notch portion 221 located at the communication position of the guide groove 213 and the slot opening of the mounting groove 211 can simultaneously communicate the guide groove 213 and the external space.

[0064] It can be understood that by providing the notch portion 221, the slot width of the guide groove 213 at the communication position with the limiting groove 212 and / or the communication position of the guide groove 213 with the slot opening of the mounting groove 211 (i.e. the communication position with the external space) can be expanded, so as to improve the smoothness of the first connecting piece 13 entering the guide groove 213 from the communication position of the guide groove 213 with the slot opening of the mounting groove 211, improve the fault tolerance of the first connecting piece 13 entering the guide groove 213, and improve the smoothness of the first connecting piece 13 entering the limiting groove 212 from the guide groove 213, improve the fault tolerance of the first connecting piece 13 entering the limiting groove 212, thereby reducing the interference between structures, facilitating user use, and improving use convenience.

[0065] In an embodiment, the distance between the second connecting member 22 and the bottom wall of the mounting groove 211 gradually decreases along the groove wall of the mounting groove 211.

[0066] It can be understood that the distance between the second connecting member 22 and the bottom wall of the mounting groove 211, that is, the groove width of the limiting groove 212, gradually changes and gradually decreases along the groove wall of the mounting groove 211. When the sensor main body 11 and the transmitter main body 21 relatively rotate, the first connecting member 13 rotates along the limiting groove 212, the first connecting member 13 gradually abuts 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, and the locking effect between the sensor 1 and the transmitter 2 can be ensured, and the stability of the connection between the two can be ensured.

[0067] In an embodiment, the transmitter 2 further comprises a limiting protrusion, and the limiting protrusion is arranged in the limiting groove 212; the limiting protrusion is located between the second connecting member 22 and the bottom wall of the mounting groove 211.

[0068] In the embodiment, the limiting protrusion protrudes away from the side wall of the limiting groove 212, and the limiting protrusion is arranged between the second connecting member 22 and the bottom wall of the mounting groove 211. The limiting protrusion can be connected to the second connecting member 22, or can be arranged separately from the second connecting member 22, and the limiting protrusion is smoothly connected to the groove wall of the limiting groove 212.

[0069] It can be understood that the limiting protrusion arranged on the side wall of the limiting groove 212 can limit and fix the first connecting member 13 when the first connecting member 13 moves along the limiting groove 212, so that the first connecting member 13 is prevented from being separated from the limiting groove 212 and sliding out of the guide groove 213 due to a small external force, and the transmitter 2 and the sensor 1 are prevented from being separated, so as to effectively enhance the abutting force and connection stability of 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.

[0070] In an embodiment, as shown in Figures 1 to 3 and Figures 5 to 7 The sensor 1 further comprises a first limiting member 14, and the first limiting member 14 and the first connecting member 13 are arranged separately on the sensor main body 11; the transmitter 2 further comprises a second limiting member 23, and the second limiting member 23 and the mounting groove 211 are arranged separately on the transmitter main body 21. In the assembled state, the first limiting member 14 abuts against the second limiting member 23.

[0071] In the embodiment, the first limiting member 14 and the second limiting member 23 can be protruding structures or elastic structures, wherein the first limiting member 14 and the first connecting member 13 are spaced apart on the sensor main body 11, and the second limiting member 23 and the mounting groove 211 are spaced apart on the transmitter main 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. For example, a first inclined surface is arranged on one side of the first limiting member 14, and a second inclined surface is arranged on one side of the second limiting member 23, and the first inclined surface and the second inclined surface abut against each other to achieve mutual abutment and mutual limitation of the first limiting member 14 and the second limiting member 23. Alternatively, one of the first limiting member 14 and the second limiting member 23 is a ball structure, and the other of the first limiting member 14 and the second limiting member 23 is provided with a groove. When the first limiting member 14 abuts against the second limiting member 23, the ball structure can be limited in the groove to achieve mutual abutment and mutual limitation of the first limiting member 14 and the second limiting member 23.

[0072] It can be understood that, through the abutment and limitation of the first limiting member 14 and the second limiting member 23, the transmitter main body 21 and the sensor main body 11 can be further limited, so as to ensure the accuracy and fixation of the relative position of the sensor main body 11 and the transmitter main body 21 in the assembled state, thereby ensuring the 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.

[0073] In an embodiment, as shown in Figures 1 to 3 and Figures 5 to 7 , the first limiting member 14 and the second limiting member 23 are located on the same side of the blood glucose detection device 100. Alternatively, as shown in Figure 3 , Figure 5 and Figure 6 , the sensor main body 11 is provided with a first accommodation groove 111, the first limiting member 14 is elastically connected to the bottom wall of the first accommodation groove 111, and the first limiting member 14 and the side wall of the first accommodation groove 111 are spaced apart. It can be understood that the first limiting member 14 is arranged in the first accommodation groove 111 and elastically connected to the bottom wall of the first accommodation groove 111, so that when the second limiting member 23 abuts against the first limiting member 14, the first limiting member 14 can elastically deform to make the first limiting member 14 and the second limiting member 23 reach the position of abutment and limitation, and the relative position between the first limiting member 14 and the second limiting member 23 is fixed, and part of the second limiting member 23 can extend into the first accommodation groove 111 to reduce the space occupation of the first limiting member 14 and the second limiting member 23, and improve the structural compactness of the overall blood glucose detection device 100.

[0074] Alternatively, as shown in Figure 5 and Figure 7As shown, the transmitter body 21 is provided with a second accommodating groove 214, and the second limiting member 23 is arranged on the bottom wall of the second accommodating groove 214. It can be understood that, by arranging the second accommodating groove 214, part of the first limiting member 14 can extend into the second accommodating groove 214, so as to reduce the space occupation of the first limiting member 14 and the second limiting member 23, and improve the structural compactness of the overall blood glucose detection device 100.

[0075] In an embodiment, as shown in Figure 5 and Figure 6 As shown, the sensor body 11 is provided with a mounting surface 112 facing the transmitter body 21, the first limiting member 14 is provided with a first side surface 141 and a second side surface 142 connected with each other, and the first side surface 141 and the second side surface 142 are arranged away from 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.

[0076] In the embodiment, the sensor body 11 is in a plate or sheet structure, so as to facilitate the overall sensor 1 to be attached to the skin of a user. The mounting surface 112 is arranged on the side of the sensor body 11 facing the transmitter body 21, so that part of the first limiting member 14 arranged on the sensor body 11 protrudes from the mounting surface 112 to abut against the second limiting member 23. The first side surface 141 and the second side surface 142 connected with each other are arranged at an angle and away from each other. In the separated state, the first side surface 141 abuts against the second limiting member 23. In the assembled state, the sensor body 11 rotates relative to the transmitter body 21. The first limiting member 14 is elastically deformed to gradually separate the first side surface 141 from the abutment against the second limiting member 23, and abut against the second limiting member 23 through the second side surface 142, so as to realize the abutment of the first limiting member 14 and the second limiting member 23.

[0077] Meanwhile, the first side surface 141 and the mounting surface 112 form an angle greater than the angle formed by the second side surface 142 and the mounting surface 112. For example, the angle formed by 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 formed by 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. The entering angle between the second limiting part 23 and the first limiting part 14 is the angle formed by the second side surface 142 and the mounting surface 112, and the exiting angle between the second limiting part 23 and the first limiting part 14 is the angle formed by the first side surface 141 and the mounting surface 112. A smaller entering angle is more conducive to the mutual abutment of the second limiting part 23 and the first limiting part 14, and the elastic deformation of the first limiting part 14 is facilitated to achieve the abutment of the second limiting part 23 and the second side surface 142, thereby facilitating the assembly and connection between the sensor main body 11 and the transmitter main body 21. A larger exiting angle can also improve the limiting abutment effect of the first limiting part 14 and the second limiting part 23, avoid disengagement of the first limiting part 14 and the second limiting part 23 due to misoperation, and ensure the connection stability between the transmitter 2 and the sensor 1, thereby ensuring the normal and continuous operation of the blood glucose detection device 100 and improving the stability and continuity of blood glucose detection.

[0078] In an embodiment, as shown in Figures 1 to 4 and Figure 6 and Figure 7 The transmitter main body 21 is also provided with a guide groove 215, and the sensor 1 further includes guide parts 15. The guide parts 15 are arranged at both ends of the sensor main body 11 and are spaced apart from the first connecting parts 13. In the assembled state, the guide parts 15 are limited in the guide grooves 215.

[0079] In this embodiment, the guide groove 215 is arranged on the transmitter main body 21, the guide groove 215 is arranged at both ends of the transmitter main body 21 and is spaced apart from the mounting groove 211, the guide part 15 is arranged on the sensor main body 11, and the guide part 15 and the first connecting part 13 are arranged at both ends of the sensor main body 11 and are spaced apart from each other. In the assembled state, when the first connecting part 13 is limited in the mounting groove 211, the guide part 15 is limited in the guide groove 215.

[0080] Meanwhile, the guide groove 215 is preferably an arc-shaped groove, and the center of curvature of the arc-shaped groove is the groove center of the mounting groove 211, so that when the transmitter main body 21 and the sensor main body 11 rotate relative to each other, the guide part 15 can extend into the guide groove 215 in the rotation direction. The guide groove 215 is not limited to being arranged on the transmitter main body 21, and the guide part 15 is not limited to being arranged on the sensor main body 11. For example, the guide groove 215 is arranged on the sensor main body 11, and the guide part 15 is arranged on the transmitter main body 21. This is not limited herein.

[0081] It can be understood that by setting the guide groove 215 and the guide 15, the emitter body 21 and the sensor body 11 can be further limited to ensure the accuracy and fixation of the relative position of the sensor body 11 and the emitter body 21 in the assembled state, so as to ensure the stable circuit conduction and signal conduction between the sensor 1 and the emitter 2, ensure the normal and continuous work of the blood glucose detection device 100, and improve the stability and continuity of blood glucose detection.
