Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0023] The present invention provides a blood sugar detection device 100, please refer to Figures 1 to 7 As shown, the blood glucose detection device 100 includes a sensor 1, a transmitter 2 and a quick-release assembly 3, the quick-release assembly 3 includes a first snap-in component 31 and a button 32, the button 32 includes a button portion 322 and a snap-in component 3222 connected to each other, the button portion 322 is inserted into one of the sensor 1 and the transmitter 2, the first snap-in component 31 is provided in the other of the sensor 1 and the transmitter 2, the first snap-in component 31 is snap-fitted with the snap-in component 3222 so that the sensor 1 and the transmitter 2 are detachably connected; the button portion 322 is configured to move closer to or away from the first snap-in component 31 by pressing and driving the snap-in component 3222.

[0024] In this embodiment, the blood glucose detection device 100 is a medical device that can monitor blood glucose levels. The blood glucose detection device 100 can continuously and in real time detect 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. Different from the traditional finger-pricking blood test, the sensor 1 in the blood glucose detection device 100 is attached to the skin to achieve continuous blood glucose detection.

[0025] Specifically, the blood glucose detection device 100 generally includes a sensor 1 and a transmitter 2. The sensor 1 is generally attached to human skin, such as the upper arm or abdomen, and glucose oxidase is arranged inside the sensor 1. 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 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 acquired 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 data, analyze data, trace data, etc.

[0026] It is understandable that after the sensor 1 is used for a long time, the glucose oxidase in the sensor 1 used to detect blood sugar will gradually be exhausted, or the tape in the sensor 1 used to adhere to the user's skin will gradually lose its stickiness, and the adhesion will decrease, resulting in the sensor 1 being unable to adhere closely to the skin for blood sugar detection, causing a decrease in detection accuracy.

[0027] That is, the sensor 1 needs to be replaced at this time, and then the sensor 1 and the transmitter 2 in the traditional blood glucose detection device 100 are an integrated structure. For example, the sensor 1 and the transmitter 2 share the same packaging structure and the same circuit system. When the sensor 1 is replaced, the transmitter 2 needs to be replaced together, resulting in waste of related structures and components of the transmitter 2, and increasing the use cost of the blood glucose detection device 100; at the same time, the structure in which the transmitter 2 and the sensor 1 are arranged as one body also makes the overall structure size of the blood glucose detection device 100 larger, and the user has a strong sense of foreign body and discomfort when wearing it in daily life, which affects the comfort and convenience of daily use.

[0028] Based on the above problems, the sensor 1 and the transmitter 2 in the blood glucose detection device 100 are configured as a detachable structure, and the sensor 1 and the transmitter 2 are detachably connected. For example, the above-mentioned button 32 is provided on the transmitter 2, and a buckle or a slot structure is provided on the corresponding button 32 of the sensor 1. When the user presses the button 32, the button 32 is connected or separated from the buckle or the slot.

[0029] By configuring the sensor 1 and the transmitter 2 as two separable components, on the one hand, when the glucose oxidase inside the sensor 1 is exhausted or the adhesion to the skin decreases, only the sensor 1 can be replaced and the original transmitter 2 can be retained to improve the recycling of the transmitter 2 and reduce the overall use cost of the blood glucose detection device 100. On the other hand, after the user attaches the sensor 1 to the skin, the transmitter 2 can be installed when the blood glucose information needs to be obtained, and the transmitter 2 can be removed by a detachable structure such as a button 32 when it is not needed, so as to reduce the weight and discomfort caused by wearing and improve the comfort and convenience of use.

[0030] In this embodiment, the sensor 1 includes a mounting plate 12, a flexible circuit board 14, a conductive elastic pin and other structures. The flexible circuit board 14 and the conductive elastic pin are arranged on the mounting plate 12, and the conductive elastic pin is electrically connected to the flexible circuit board 14. At the same time, the flexible circuit board 14 is also provided with a detection electrode for detecting the blood sugar level of the user. The clamping part is arranged on the mounting plate 12. At the same time, the transmitter 2 includes a base shell, a circuit board and a conductive terminal. The circuit board and the conductive terminal are arranged in the base shell. The circuit board is provided with a transmitter electrically connected to the conductive terminal, such as a Bluetooth transmitter, a radio frequency transmitter, a Zigbee transmitter 2, etc., which is not limited here. When the sensor 1 and the transmitter 2 are connected, the conductive terminal is electrically connected to the conductive elastic pin in the sensor 1 to obtain the blood sugar data in the sensor 1 and transmit it to an external signal receiving device through the transmitter.

[0031] In this embodiment, the blood glucose detection device 100 also includes a quick-release assembly 3, the quick-release assembly 3 includes a first snap-in component 31 and a button 32, the button 32 includes a button portion 322 and a snap-in portion 3222 connected to each other, one of the sensor 1 and the transmitter 2 is provided with a mounting hole, the button portion 322 is movably arranged in the mounting hole, and the button portion 322 can be elastically connected to the sensor 1 or the transmitter 2 to provide the user with a better pressing experience, the snap-in portion 3222 is connected to the button portion 322, and the snap-in portion 3222 can be snap-fitted with the first snap-in component 31 to realize a detachable connection between the sensor 1 and the transmitter 2.

[0032] It can be understood that when the sensor 1 and the transmitter 2 are connected to each other, the button portion 322 of the button 32 is pressed to connect or separate the clamping portion 3222 from the first clamping member 31. If two buttons 32 are provided, the two buttons 32 are pressed to make the two buttons 32 move relative to each other to change the relative distance between the two, so that the first clamping member 31 extends into the clamping portion 3222 and is clamped with the clamping portion 3222. The first clamping member 31 can be a barbed hook, or a clamping convexity or a limiting protrusion, so that the first clamping member 31 limits the button 32 to maintain the mutual connection between the first clamping member 31 and the button 32, thereby realizing the mutual connection between the sensor 1 and the transmitter 2.

[0033] By setting two buttons 32 that are arranged opposite to each other, on the one hand, the user needs to press the two buttons 32 at the same time to unlock the sensor 1 and the transmitter 2, thereby preventing a single button 32 from being easily triggered during daily use and causing abnormal separation of the sensor 1 and the transmitter 2, thereby reducing the risk of loss and damage of the transmitter 2 or the sensor 1. On the other hand, it is also convenient for the user to operate the two buttons 32 with one hand, such as using two fingers to press the buttons 32 at the same time, effectively improving the convenience and stability of one-handed operation.

[0034] In another embodiment of the present invention, the button portion 322 is provided with a pressing surface 3221, and the user presses the button portion 322 and the key 32 by contacting the pressing surface 3221. The pressing surface 3221 can be a curved surface, such as a curved surface with protrusions at both ends and a depression in the middle, to facilitate users to quickly position, or it can be an inclined surface to facilitate users to hold with both hands and quickly press the key 32.

[0035] The blood glucose detection device 100 of the technical solution of the present invention includes a sensor 1, a transmitter 2 and a quick-release assembly 3, the quick-release assembly 3 includes a first snap-in component 31 and a button 32, the button 32 includes a button portion 322 and a snap-in component 3222 connected to each other, the button portion 322 is inserted into one of the sensor 1 and the transmitter 2, the first snap-in component 31 is provided in the other of the sensor 1 and the transmitter 2, the first snap-in component 31 is snap-fitted with the snap-in component 3222 to make the sensor 1 and the transmitter 2 detachably connected; the button portion 322 is configured to drive the snap-in component 3222 to move by pressing, and by providing the button 32 and the first snap-in component 31, on the basis of improving the stability of the detachable connection between the transmitter 2 and the sensor 1, it is also convenient for the user to operate with one hand, thereby improving the convenience and stability of the user during use.

[0036] In one embodiment, if Figure 2 and Figure 3 As shown, the quick-release assembly 3 includes at least two first clamping parts 31, and each first clamping part 31 is respectively arranged at two opposite side edges 4 of the sensor 1 or the transmitter 2; optionally, the quick-release assembly 3 includes at least two buttons 32, and each button 32 is respectively arranged at two opposite side edges 4 of the sensor 1 or the transmitter 2.

[0037] In this embodiment, the quick-release assembly 3 includes at least two first clamping members 31, and the sensor 1 or the transmitter 2 has two opposite side edges 4. For example, the sensor body 11 of the sensor 1 or the transmitter body 21 of the transmitter 2 is a plate-shaped or sheet-shaped structure, and the extension directions of the two opposite side edges 4 are roughly the same, wherein each first clamping member 31 is respectively arranged at the two opposite side edges 4 of the sensor body 11 or the transmitter body 21, so that the first clamping members 31 located on the two opposite side edges 4 are arranged oppositely, and at the same time, the edge extension directions of the transmitter body 21 and the sensor body 11 are roughly consistent, so that the transmitter body 21 also has two opposite edges, and two buttons 32 are arranged at the two opposite edges of the transmitter body 21 or the sensor body 11, and each button 32 is clamped with at least one first clamping member 31 on one side edge, and the two buttons 32 are simultaneously clamped with the first clamping members 31 located on the two opposite edges.

[0038] It can be understood that the two buttons 32 are respectively arranged at the two opposite side edges 4 of the transmitter body 21 or the sensor body 11, so that the two buttons 32 can be arranged relatively spaced apart. Correspondingly, the first clamping parts 31 are also relatively arranged at the two opposite edges of the sensor body 11 or the transmitter body 21, so that each button 32 can be clamped with one or more first clamping parts 31 at the same time, and the two buttons 32 can realize a detachable connection with each first clamping part 31, thereby realizing the mutual connection and separation of the transmitter 2 and the sensor 1.

[0039] In the case where it is inconvenient for the user to operate with both hands or to directly observe the position of the button 32, the user can quickly locate the two opposite side edges 4 of the sensor body 11 or the transmitter body 21 by using the thumb and index finger of one hand (other fingers are also acceptable, only the thumb and index finger are used as examples and are not limited here), so as to quickly locate the button 32, and by pressing the buttons 32 at the same time, each button 32 can be disconnected from or connected to the corresponding first clamping member 31, so as to facilitate the user to quickly locate with one hand and quickly disassemble and assemble the transmitter 2 with one hand, effectively improving the convenience and stability of operation.

[0040] In one embodiment, if Figure 2 As shown, the quick-release assembly 3 also includes a second clamping member 33, which is disposed on one of the sensor 1 and the transmitter 2; the other of the sensor 1 and the transmitter 2 is provided with a limiting groove 6, and the second clamping member 33 is limited in the limiting groove 6.

[0041] It can be understood that the first clamping member 31 and the second clamping member 33 have different functions, wherein the first clamping member 31 is used to connect with the button 32, such as providing a clamping groove or a clamping hole in the button 32 to realize the detachable connection between the first clamping member 31 and the button 32, thereby realizing the detachable connection between the transmitter 2 and the sensor 1, and at the same time, the second clamping member 33 is limitedly connected with the transmitter body 21 or the sensor body 11, such as providing a limiting groove 6 on the transmitter body 21 or the sensor body 11, the second clamping member 33 can extend into the limiting groove 6, and limit abut and / or limit clamp with the limiting groove 6, and the second The clamping member 33 can limit the position of the transmitter 2 and the sensor 1, maintain a tight connection between the sensor 1 and the transmitter 2, and compensate for the connection gap between the first clamping member 31 and the button 32. By setting the first clamping member 31 and the second clamping member 33, the tight connection between the transmitter 2 and the sensor 1 can be maintained on the basis of realizing a detachable connection between the sensor 1 and the transmitter 2, that is, to ensure that the circuit conduction structure between the transmitter 2 and the sensor 1 is stably connected, and avoid possible vacant positions and gaps caused by the separate setting of the first clamping member 31, so as to ensure the continuity, stability and detection accuracy of the blood glucose detection device 100 during operation.

[0042] At the same time, when the user accidentally touches the button 32, causing the button 32 and the first clamping member 31 to be abnormally separated, the sensor 1 and the transmitter 2 are still connected to each other through the second clamping member 33, thereby preventing the transmitter 2 from being directly separated from the sensor 1 and reducing the risk of loss and damage of the transmitter 2.

[0043] In one embodiment, if Figure 2 As shown, the second clamping member 33 is disposed at the edge of the sensor body 11 or the transmitter body 21 and is located between two first clamping members 31 that are disposed opposite to each other.

[0044] In this embodiment, the sensor body 11 or the transmitter body 21 also has a middle edge 5 connecting the two side edges 4, and the middle edge 5 and the side edges 4 together form the boundary of the sensor body 11. The second clip 33 is arranged at the middle edge 5, and the second clip 33 is located between the two oppositely arranged first clips 31. At the same time, the clip may include at least two second clips 33, and at least two second clips 33 are located at the same middle edge 5, so that each second clip 33 and each first clip 31 can be arranged at intervals on the edge of the sensor body 11 in a fully enclosed manner or a semi-enclosed manner to be connected to the transmitter 2.

[0045] It can be understood that when the user disassembles the sensor 1 and the transmitter 2, after the user presses the buttons 32 on both sides in a clamping manner, the connection relationship between the second clamping member 33 and the transmitter body 21 is still retained to prevent the sensor 1 and the transmitter 2 from being directly separated, or when the user accidentally touches the button 32, causing the button 32 and the first clamping member 31 to be abnormally separated, the sensor 1 and the transmitter 2 are still connected to each other through the second clamping member 33, thereby preventing the transmitter 2 from being directly separated from the sensor 1 and reducing the risk of loss and damage of the transmitter 2. In addition, the second clamping member 33 is arranged between the two oppositely arranged first clamping members 31, and the normal connection and disassembly of the first clamping member 31 and the button 32 are not affected. At the same time, each second clamping member 33 cooperates with the first clamping member 31. When the first clamping member 31 and the button 32 are mutually clamped, the second clamping member 33 can also connect and limit the edges of the sensor 1 and the transmitter 2, thereby ensuring the stability of the connection between the transmitter 2 and the sensor 1.

[0046] In one embodiment, the height of the first clamping member 31 along the direction perpendicular to the mounting surface 111 is greater than the height of the second clamping member 33 along the direction perpendicular to the mounting surface 111 .

[0047] It can be understood that a limiting groove 6 is provided on one side edge of the transmitter body 21 or the sensor body 11. When the first clip 31 is connected to the button 32, the second clip 33 is limited in the limiting groove 6. At the same time, the main body of the first clip 31 and the main body of the second clip 33 are both provided on the mounting surface 111 and extend in a direction away from the mounting surface 111. At the same time, the height of the first clip 31 in a direction perpendicular to the mounting surface 111 is greater than the height of the second clip 33 in a direction perpendicular to the mounting surface 111. When installed in connection with the sensor 1, the first clamping member 31 can first contact the button 32, and then perform secondary limiting with the second clamping member 33 through the limiting groove 6. When the sensor 1 and the transmitter 2 are separated from each other, the second clamping member 33 with a lower height can also be separated from the limiting groove 6 more quickly and conveniently, which is convenient for the user to operate with one hand, avoiding the second clamping member 33 still being limited and restrained after the second clamping member 33 has been separated from the first clamping member 31 through the button 32, thereby improving the stability and convenience of one-handed operation.

[0048] In one embodiment, if Figures 1 to 3 As shown, the sensor 1 includes a sensor body 11 and a conductive seat 13. The sensor body 11 is provided with a mounting surface 111. The conductive seat 13, the first clamping member 31 and the second clamping member 33 are arranged on the mounting surface 111. The second clamping member 33 and at least part of the first clamping member 31 are arranged around the conductive seat 13.

[0049] In this embodiment, a sensor body 11 is provided in a plate or sheet shape, and is provided with a mounting surface 111. Each first clamping member 31 and each second clamping member 33 are provided on the mounting surface 111. Specifically, the sensor 1 includes a mounting plate 12 and a flexible circuit board 14. The mounting plate 12 is used to mount and place the flexible circuit board 14. The mounting plate 12 is in a plate or sheet structure, and the mounting plate 12 has a maximum surface area of ​​the mounting surface 111. The flexible circuit board 14 is provided on the side of the mounting plate 12 facing away from the mounting surface 111. At the same time, the mounting plate 12 is provided with a conductive seat 13. The conductive seat 1 3 is arranged on the mounting surface 111 of the mounting seat, a conductive spring pin (which can also be a conductive capsule) is arranged in the mounting seat, the transmitter 2 is provided with a conductive contact, the conductive contact is arranged on the transmitter body 21, one end of the conductive spring pin can be connected with the conductive contact circuit when the transmitter 2 is connected to the sensor 1, and the other end of the conductive spring pin is electrically connected to the flexible circuit board 14, wherein the conductive seat 13 is arranged at the middle position of the mounting plate 12 or at the end of the mounting plate 12 or at the edge of the mounting plate 12, and the first clamping member 31 and the second clamping member 33 arranged on the mounting plate 12 are arranged around the conductive seat 13.

[0050] It can be understood that the sensor 1 includes a plurality of conductive elastic pins, which are arranged in the conductive seat 13 so as to conduct the circuit with the transmitter 2 when the transmitter 2 is connected to the sensor 1. On the basis of the connection between the button 32 and the first clamping member 31, the transmitter body 21 and the second clamping member 33 are also connected to each other in a limiting manner. On the basis of keeping the sensor 1 and the transmitter 2 tightly connected, the first clamping member 31 and the second clamping member 33 surrounding the conductive seat 13 can make the area of ​​the transmitter 2 corresponding to the conductive seat 13 tightly abut against the conductive seat 13, thereby ensuring that the conductive elastic pins located in the conductive seat 13 enclosed by the first clamping member 31 and the second clamping member 33 tightly abut against the conductive contacts, so as to ensure the stable circuit connection between the conductive contacts and the conductive elastic pins, avoid the generation of virtual connection, and ensure the connection stability and detection continuity of the sensor 1 and the transmitter 2.

[0051] In one embodiment, if Figure 4 , Figure 5 as well as Figure 7 As shown, the button 32 also includes a bearing portion 321 and an elastic member 3223. The bearing portion 321 and the button portion 322 are spaced apart, the clamping portion 3222 is slidably connected to the bearing portion 321, one end of the elastic member 3223 is connected to the button portion 322, and the other end of the elastic member 3223 is connected to the bearing portion 321.

[0052] In this embodiment, the button 32 includes a bearing portion 321, a button portion 322, a clamping portion 3222 and an elastic member 3223. The bearing portion 321 of the button 32 is disposed on the sensor body 11 or the transmitter body 21. The bearing portion 321 is the main supporting structure of the button 32 for installing the button portion 322. The bearing portion 321 can be a mounting frame, a mounting table, a mounting plate 12 or other structures, which are not limited here.

[0053] The clamping part 3222 and the elastic member 3223 are connected to the button part 322, wherein the clamping part 3222 is slidably connected to the bearing part 321, such as one of the bearing part 321 and the clamping part 3222 is provided with a guide groove, a slide groove 3213a, a sliding sleeve and other structures, and the other of the bearing part 321 and the clamping part 3222 is a guide column, a guide bar, a guide block, a shaft, a roller and other structures, and the guide column, guide bar, guide block, shaft, roller can be extended into the guide groove, the slide groove 3213a, the sliding sleeve, so as to realize the bearing part 321 and the clamping part 322 2 sliding connection; the elastic member 3223 is elastically connected to the bearing portion 321, and the elastic member 3223 can be elastically connected to the bearing portion 321 through an elastic structure such as a spring, a spring sheet, an elastomer, etc. When the user presses the button portion 322, the elastic structure between the elastic member 3223 and the bearing portion 321 produces elastic deformation, and at the same time, the clamping portion 3222 slides relative to the bearing portion 321, so that the overall position of the button portion 322 changes, thereby realizing connection or separation with the buckle or slot in an external device (such as sensor 1).

[0054] Further, the button portion 322 includes at least two elastic members 3223, and each elastic member 3223 is centrally symmetrically arranged around the clamping portion 3222, that is, each elastic member 3223 is located around the clamping portion 3222 and is evenly spaced around the clamping portion 3222 as the center. For example, the button portion 322 includes two elastic members 3223, and the two elastic members 3223 are located on both sides of the clamping portion 3222 and are symmetrically arranged around the clamping portion 3222 as the center. In this case, the button portion 322 is arranged in a long strip structure, the two elastic members 3223 are located at both ends, and the clamping portion 3222 is located in the middle; or the button portion 322 includes four elastic members 3223, and the four elastic members 3223 are located around the clamping portion 3222 and are symmetrically spaced around the clamping portion 3222 as the center. In this case, the button portion 322 is arranged in a circular or square structure.

[0055] It can be understood that the sensor 1 is attached to the user's arm or abdomen, and the user usually operates the button 32 with one hand to achieve the separation or connection of the transmitter 2 and the sensor 1. In addition, it is not convenient for the user to visually observe the position of the button 32. The user usually locates the position of the button 32 directly by touching it, and directly presses it to achieve the separation or connection of the transmitter 2 and the sensor 1. When pressing, the elastic members 3223 are arranged symmetrically around the clamping portion 3222, so that the stability and balance of the connection between the button portion 322 and the bearing portion 321 can be maintained. No matter whether the user presses to a certain local position or an extreme position such as the end or side of the button portion 322, the clamping portion 3222 located in the middle of the elastic member 3223 can be driven to slide relative to the bearing portion 321, so as to achieve the precise change of the position of the button portion 322 relative to the bearing portion 321, reduce the probability of deflection and jamming of the button portion 322 when pressed, improve the stability and smoothness of the button portion 322 when moving relative to the bearing portion 321, and improve the convenience and comfort of the user's direct touch operation.

[0056] The key 32 of the technical solution of the present invention includes a bearing portion 321, a button portion 322, a clamping portion 3222 and an elastic member 3223. The bearing portion 321 is the main supporting structure of the key 32, which is used to support the button portion 322. The button portion 322 includes a clamping portion 3222 and at least two elastic members 3223. The clamping portion 3222 is slidably connected to the bearing portion 321. The elastic members 3223 are elastically connected to the bearing portion 321 and the button portion 322. The elastic members 3223 are symmetrically arranged around the center of the clamping portion 3222. By arranging the elastic members 3223 elastically connected to the bearing portion 321 around the clamping portion 3222, the surrounding elastic members 3223 can all generate stable support, ensuring the smoothness and stability of the clamping portion 3222 and the bearing portion 321 when sliding relative to each other, thereby improving the stability and smoothness of the button portion 322 when moving relative to the bearing portion 321, reducing the jamming caused by uneven force, and improving the user experience.

[0057] In one embodiment, if Figures 4 to 7 As shown, the bearing portion 321 is provided with a guide groove 3213, and the clamping portion 3222 is slidably arranged in the guide groove 3213; the clamping portion 3222 is provided with a limiting space 3222c, and the limiting space 3222c is connected to the guide groove 3213, and the first clamping member 31 extends into the limiting space 3222c and limits the clamping portion 3222.

[0058] It can be understood that the bearing portion 321 is provided with a guide groove 3213, and the clamping portion 3222 is slidably arranged in the guide groove 3213. At the same time, when the button portion 322 is pressed, the direction of elastic compression of the elastic member 3223 relative to the bearing portion 321 is consistent with the sliding direction of the clamping portion 3222 relative to the guide groove 3213, so that in the process of pressing the button portion 322, the button portion 322 maintains a single movement direction relative to the bearing portion 321, avoiding the user from pressing the button portion 322 to produce movement in other directions, and the single movement direction also makes the pressing feel clear and consistent, giving the user faster and clearer pressing feedback, making the pressing process more linear, ensuring the user's convenience in one-handed operation and in the absence of visual observation, so that the user can more easily perceive the triggering of the button 32, and avoiding the occurrence of jamming or tilting during the pressing process.

[0059] In one embodiment, if Figure 7 As shown, the clamping portion 3222 includes a connecting section 3222a and a limiting section 3222b, which together form a limiting space 3222c; the connecting section 3222a is spaced apart from the side wall of the guide groove 3213, and the first clamping member 31 is limitedly abutted against the limiting section 3222b.

[0060] The locking cam 3222a is provided with a first cam 3224a which is adapted to move the first locking cam 3222a towards the locking cam 3222a, and the second cam 3224a is provided with a second cam 3224b which is adapted to move the first locking cam 3222a towards the locking cam 3222a.

[0061] In one embodiment, if Figure 6As shown, the two side walls of the guide groove 3213 along the sliding direction of the connecting section 3222a are provided with sliding grooves 3213a, and the side walls of the sliding groove 3213a are continuous cylindrical curved surfaces; the connecting section 3222a is slidably arranged in the sliding groove 3213a, and the side of the connecting section 3222a facing the sliding groove 3213a is a continuous cylindrical curved surface; it can be understood that the guide surface is set as a cylindrical surface, and at the same time, the guide surface of the guide groove 3213 corresponding to the cylindrical surface structure is also provided with a guide groove side wall of a cylindrical surface structure, so that the clamping portion 3222 is limited and slidably arranged on the guide groove In the groove 3213, by providing a cylindrical guide surface, the installation accuracy of the clamping part 3222 and the guide groove 3213 can be improved, the centering ability of the clamping part 3222 and the guide groove 3213 can be improved, and the clamping part 3222 can slide in a straight line along the guide groove 3213, and the smoothness and stability of the clamping part 3222 and the bearing part 321 when sliding relative to each other can be ensured, thereby improving the stability and smoothness of the button part 322 when it moves relative to the bearing part 321, reducing the jamming caused by uneven force, and improving the user experience. Optionally, the bearing part 321 is also provided with a clearance groove 3213b, which is located on the side wall of the guide groove 3213 along the direction in which the first clamping member 31 extends into the limiting space 3222c. By providing the clearance groove 3213b to avoid the first clamping member 31, it is convenient for the first clamping member 31 and the clamping part 3222 to be mutually clamped.

[0062] In one embodiment, if Figure 4 , Figure 5 as well as Figure 7 As shown, the button portion 322 further includes at least two limiting portions 3224 , which are slidably connected to the bearing portion 321 ; each limiting portion 3224 is disposed corresponding to an elastic member 3223 , and are centrally symmetrically disposed around the clamping portion 3222 .

[0063] In this embodiment, the limiting portion 3224 is connected to the bearing portion 321 in a limiting sliding manner so as to gradually compress the pressing gap when the button portion 322 is pressed. The limiting portion 3224 and the clamping portion 322 slide relative to the bearing portion 321 at the same time. After the pressing is completed, under the action of the elastic force between the elastic member 3223 and the bearing portion 321, the button portion 322 is reset relative to the bearing portion 321 as a whole, and the pressing gap between the button portion 322 and the bearing portion 321 is restored. At this time, the limiting portion 3224 is connected to the bearing portion 321 in a limiting manner so as to limit the button portion 322 as a whole, thereby ensuring that the button portion 322 moves within a certain range relative to the bearing portion 321, and avoiding excessive movement or separation of the button portion 322 and the bearing portion 321.

[0064] Among them, the limited sliding connection between the limiting portion 3224 and the bearing portion 321 can be that a slide groove 3213a, a guide groove and other structures are set on one of the bearing portion 321 or the limiting portion 3224, and a slider is set on the other of the bearing portion 321 or the limiting portion 3224, the slider slides in the slide groove 3213a, and has an extreme position in the extension direction of the groove body of the slide groove 3213a to limit the sliding distance of the slider in the slide groove 3213a, thereby limiting the sliding distance of the limiting portion 3224 and the overall button portion 322 relative to the bearing portion 321, so as to maintain the connection between the button portion 322 and the bearing portion 321 under the action of the elastic force of the elastic connection between the elastic member 3223 and the bearing portion 321.

[0065] Furthermore, the button portion 322 includes at least two limiting portions 3224, each limiting portion 3224 is arranged corresponding to an elastic member 3223, and at the same time, each limiting portion 3224 is arranged symmetrically around the clamping portion 3222 like the elastic member 3223. When the button 32 is pressed, the clamping portion 3222 slides relative to the bearing portion 321, and at the same time, the limiting portions 3224 located around the clamping portion 3222 also slide synchronously and in the same direction, thereby ensuring the stability and smoothness of the overall button portion 322 when pressed. In addition, each limiting portion 3224 is arranged corresponding to an elastic member 3223, which also That is, each limiting portion 3224 is arranged around an elastic member 3223, such as the limiting portion 3224 is arranged between the elastic member 3223 and the clamping portion 3222, or the elastic member 3223 is located between the limiting portion 3224 and the clamping portion 3222, so that no matter where the user touches the button portion 322, it can ensure that there is a uniform elastic compression deformation between each elastic member 3223 and the bearing portion 321, and the elastic force can be dispersed, so that the overall button portion 322 moves relative to the bearing portion 321 with a uniform force and direction, reducing the jamming caused by uneven force and improving the user experience.

[0066] Specifically, the bearing part 321 includes a bearing body 3211 and a limiting member, and the limiting member is arranged on the bearing body 3211; the limiting part 3224 is provided with a limiting groove 3224a, and at least part of the limiting member is slidingly arranged in the limiting groove 3224a. The limiting member can be a limiting block 3212 or a limiting protrusion, etc. The limiting member extends into the limiting groove 3224a and can slide in the limiting groove 3224a, and the groove wall of the limiting groove 3224a also limits the sliding distance of the limiting member.

[0067] In another embodiment of the present invention, the supporting body 3211 is provided with at least two installation grooves, and each installation groove is symmetrically arranged around the center of the clamping portion 3222; the elastic member 3223 is limited in the installation groove, and at least part of the elastic member 3223 extends into the installation groove. By setting the installation groove, the elastic member 3223 can be limited and guided, so that the elastic member 3223 is compressed in a predetermined direction so that the button portion 322 moves toward or away from the supporting portion 321, thereby improving the stability and guidance of the button 32 during the pressing process.

[0068] In one embodiment, each elastic member 3223 is located between the clamping portion 3222 and a limiting portion 3224 .

[0069] It is understandable that, in the process of pressing the button 32, the elastic connection between the elastic member 3223 of the button 32 and the bearing portion 321 is subjected to a large force. By locating each elastic member 3223 between the clamping portion 3222 and a limiting portion 3224, the elastic force of the clamping portion 3222 and the limiting portion 3224 on both sides of the elastic member 3223 can effectively disperse the pressure during pressing, reduce the stress concentration at the connection point between the single elastic member 3223 and the bearing portion 321, and thus enhance the stability of the entire button 32 during pressing. At the same time, arranging the elastic member 3223 closer to the clamping portion 3222 relative to the limiting portion 3224 can also reduce the force of the user when pressing the button 32, and improve the ease of one-handed operation of the user.

[0070] In one embodiment, the clamping portion 3222 , the elastic members 3223 , and the limiting portions 3224 are arranged at intervals along a straight line.

[0071] In this embodiment, each elastic member 3223 is located on both sides of the clamping portion 3222, and at the same time, each limiting portion 3224 is located on the side of the elastic member 3223 away from the clamping portion 3222, so that the clamping portion 3222, each elastic member 3223 and each limiting portion 3224 are arranged at intervals along a straight line, and the direction in which the clamping portion 3222, each elastic member 3223 and each limiting portion 3224 are arranged at intervals is defined as a first direction. The transmitter 2 and the sensor 1 have a thickness direction, which is roughly parallel to the skin surface of the user, wherein the first direction is arranged at an angle to the thickness direction, such as the first direction is parallel or perpendicular to the thickness direction, and preferably, the first direction is perpendicular to the thickness direction.

[0072] It can be understood that the clamping portion 3222, each elastic member 3223 and each limiting portion 3224 are arranged at intervals along a straight line, and preferably, the clamping portion 3222, each elastic member 3223 and each limiting portion 3224 are arranged at intervals approximately in a direction perpendicular to the thickness of the transmitter 2, thereby improving the compactness of the button 32, reducing the space occupied by the transmitter in the thickness direction, and reducing the size of the transmitter 2 protruding away from the user's skin, so that the transmitter 2 fits the user's skin better, and reduces the foreign body sensation and dragging sensation generated by the user when wearing the transmitter 2, thereby improving the comfort of use.

[0073] In addition, the clamping portion 3222, the elastic members 3223 and the limiting portions 3224 are arranged at intervals along a straight line, so that the button 32 can be distributed in a long strip shape at the side edge 4 of the transmitter, which makes it convenient for the user to touch the button 32 with one hand without direct visual contact. Even if a local area of ​​the button 32 is touched, the button 32 can be more easily sensed and triggered, thereby improving the fault tolerance of the use of the button 32.

[0074] In one embodiment, if Figure 4 , Figure 5 as well as Figure 7 As shown, the button 32 also includes an elastic member 3223 , which is connected to the limiting portion 3224 and sleeved on the limiting portion 3224 ; one end of the elastic member 3223 is connected to the bearing portion 321 , and the other end of the elastic member 3223 is connected to the elastic member 3223 .

[0075] In this embodiment, the elastic member 3223 is connected to the limiting portion 3224. At this time, the elastic member 3223 and the limiting portion 3224 are both located around the clamping portion 3222. The elastic member 3223 can be located between the limiting portion 3224 and the supporting body 3211, or the limiting portion 3224 can be located between the elastic member 3223 and the supporting body 3211. No limitation is made here.

[0076] At the same time, the button 32 also includes an elastic member 3223, which can be a spring or an elastomeric material structure with elastic ability. One end of the elastic member 3223 is connected to the elastic member 3223, and the other end of the elastic member 3223 is connected to the supporting body 3211 of the supporting part 321, and the elastic member 3223 is provided with an elastic cavity, and the limiting part 3224 is set as a columnar or strip structure, so that the elastic member 3223 is sleeved on the limiting part 3224.

[0077] It can be understood that when the button 32 is pressed, the elastic member 3223 is compressed, and the button portion 322 moves relative to the bearing portion 321. During the compression of the elastic member 3223, the limiting portion 3224 also slides relative to the bearing portion 321. By sleeve-arranging the elastic member 3223 on the periphery of the limiting portion 3224, so that the compression movement direction of the elastic member 3223 is consistent with the relative sliding direction of the limiting portion 3224 and the bearing portion 321, and the two move together along the same axis, not only the elastic connection between the elastic member 3223 and the bearing portion 321 is strengthened, but also the elastic connection between the elastic member 3223 and the bearing portion 321 is strengthened. The limiting sliding structure of the limiting part 3224 and the bearing part 321 is arranged on the same axis, which effectively improves the structural compactness of the button 32, so as to effectively improve the miniaturization of the transmitter 2 and the blood glucose detection device 100. At the same time, the elastic movement of the elastic member 3223 and the sliding movement of the limiting part 3224 move along the same axis, which can also improve the movement stability and smoothness of the button 32 during the pressing process, reduce the probability of deflection and jamming of the button part 322 when pressed, and improve the convenience and comfort of the user's direct touch operation.

[0078] 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.
