[0023] Please refer to Figures 1 to 7 and Figure 9 and Figure 10 As shown, the present invention provides a blood glucose detection device 100. The blood glucose detection device 100 includes a sensor 1, a transmitter 2, and a detection component 3. The sensor 1 includes a sensor main body 11 and a first conductive member 12. The first conductive member 12 is disposed on the sensor main body 11. The transmitter 2 includes a transmitter main body 21 and a second conductive member 22. The transmitter main body 21 is detachably connected to the sensor main body 11. The second conductive member 22 is disposed on the transmitter main body 21. The detection component 3 includes a first detection member 31 and a second detection member 32. The first detection member 31 is disposed on one of the transmitter main body 21 and the sensor main body 11, and the second detection member 32 is disposed on the other of the transmitter main body 21 and the sensor main body 11. The blood glucose detection device 100 has a connection state in which the transmitter 2 and the sensor 1 are connected. In the connection state, the first detection member 31 and the second detection member 32 form a detection circuit, and the detection circuit is configured to determine that the circuits of the first conductive member 12 and the second conductive member 22 are electrically connected.

[0024] In this embodiment, the blood glucose detection device 100 is a medical device capable of monitoring blood glucose levels. The blood glucose detection device 100 can continuously and real-time detect the changes in the daily blood glucose of diabetic patients and record the blood glucose data in real time. It is widely used in the daily blood glucose management of diabetic patients. In the blood glucose detection device 100 in this application, the sensor 1 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 usually attached to the human skin, such as the upper arm or abdomen. Glucose oxidase is provided inside the sensor 1. 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 wirelessly transmit the obtained blood glucose data to an external signal receiving device, such as a smart phone, a smart watch, a dedicated monitor, etc., to facilitate the user to view data, analyze data, retrieve data, etc.

[0026] It can be understood that after the sensor 1 is used for a long time, the glucose oxidase used for detecting blood glucose in the sensor 1 will gradually be exhausted, or the tape used for bonding the sensor 1 to the user's skin will gradually lose its adhesiveness, and the adhesive force will decrease, resulting in the sensor 1 being unable to closely adhere to the skin for blood glucose detection, causing a decrease in detection accuracy.

[0027] That is to say, at this time, the sensor 1 needs to be replaced. However, in the traditional blood glucose detection device 100, the sensor 1 and the transmitter 2 are of an integrated structure. For example, the sensor 1 and the transmitter 2 share the same packaging structure and the same circuit system. Replacing the sensor 1 requires replacing the transmitter 2 together, resulting in waste of the relevant structures and components of the transmitter 2 and increasing the use cost of the blood glucose detection device 100. At the same time, the integrated structure of the transmitter 2 and the sensor 1 also makes the overall structure size of the blood glucose detection device 100 relatively large, and the user has a strong sense of foreign body and discomfort during daily wearing, affecting the comfort and convenience of daily use.

[0028] By setting 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 adhesive force with the skin decreases, only the sensor 1 can be replaced, and the original transmitter 2 is retained to improve the recycling use 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 blood glucose information needs to be obtained, and can be removed through a detachable structure such as a button 213 when not needed, so as to reduce the load and discomfort caused by wearing and improve the comfort and convenience of use.

[0029] In this embodiment, the sensor body 11 includes structures such as a substrate 111, a first circuit board 15, and a first conductive member 12. The substrate 111 is a structural support component of the sensor 1. The substrate 111 can also be structures such as a base, the sensor body 11, etc. The sensor body 11 is disposed on the substrate 111. At the same time, both the first circuit board 15 and the first conductive member 12 are disposed on the substrate 111, and a sampling electrode for obtaining the glucose level in the user's tissue fluid is disposed on the first circuit board 15. The transmitter body 21 includes components such as a housing 211, a circuit board 212, and a battery. The housing 211 is the main support structure of the transmitter 2. The transmitter body 21 is disposed on the housing 211. At the same time, the battery is electrically connected to the circuit board 212, and the second conductive member 22 is electrically connected to the circuit board 212. When the sensor body 11 and the transmitter body 21 are connected to each other so that the sensor 1 and the transmitter 2 are connected to each other, the first conductive member 12 and the second conductive member 22 are electrically abutted against each other to achieve electrical signal transmission between the transmitter 2 and the sensor 1. Among them, the first conductive member 12 and the second conductive member 22 can be structures such as conductive capsules, conductive terminals, conductive contacts, conductive springs, and conductive pins, which are not limited herein.

[0030] Among them, the sensor body 11 and the transmitter body 21 can be detachably connected by a snap connection method. For example, structures such as hooks and posts are disposed on the substrate 111 of the sensor body 11, and a button 213 structure with a slot or a bayonet is disposed on the housing 211 of the transmitter body 21. When the user presses the button 213, the button 213 can be connected to or separated from the snap or the slot, or both the sensor body 11 and the transmitter body 21 are magnetic members, and the detachable connection between the transmitter 2 and the sensor 1 is achieved through the magnetic connection between the sensor body 11 and the transmitter body 21.

[0031] At the same time, such as Figure 3 and Figure 10As shown, the blood glucose detection device 100 further includes a detection component 3. The detection component 3 includes a first detection piece 31 and a second detection piece 32. The first detection piece 31 is provided on one of the transmitter main body 21 and the sensor main body 11, and the second detection piece 32 is provided on the other of the transmitter main body 21 and the sensor main body 11, such as the second circuit board 212 provided on the transmitter main body 21 or the substrate 111 provided on the sensor main body 11. Wherein, the first detection piece 31 or the second detection piece 32 provided on the transmitter main body 21 is in contact with and electrically connected to the second detection piece 32 or the first detection piece 31 provided on the substrate 111 in the connected state, and a detection circuit can be formed. If both the first detection piece 31 and the second detection piece 32 are conductive pieces, the detection circuit is an electrical circuit loop. Through the conductive connection of the first detection piece 31 and the second detection piece 32, the detection circuit forms a path. Based on this, the second circuit board 121 can recognize that the sensor 1 and the transmitter 2 are in a connected state. Among them, on the basis that both the first detection piece 31 and the second detection piece 32 are conductive pieces (such as conductive structures such as conductive contacts, conductive terminals, conductive springs, and conductive capsules), the first detection piece 31 and the second detection piece form a detection circuit. Taking the first detection piece 31 provided on the sensor 1 main body and the second detection piece 32 provided on the transmitter 2 main body 21, and the second detection piece 32 being electrically connected to the circuit board as an example, the detection circuit further includes a fixed resistance resistor, a voltage detection chip, and a current detection chip. The fixed resistance resistor is electrically connected to the first detection piece 31 or the second detection piece 32, and the voltage detection chip and the current detection chip are electrically connected to the fixed resistance resistor and the circuit board.

[0032] It can be understood that after the sensor 1 and the transmitter 2 are buckled or connected to each other, the first detection piece 31 and the second detection piece 32 are in contact or inserted with each other, and the detection circuit is turned on. At this time, based on the fixed current value generated by the fixed resistance resistor when the detection circuit is turned on, the current detection chip can detect the current in the detection circuit to confirm that the detection circuit is in a normal conduction state at this time. In the normal conduction state, the currents at the first detection piece 31 and the second detection piece 32 are balanced. After the detection circuit is abnormally disconnected, the current on one side will disappear. In this way, the current connection state of the sensor 1 and the transmitter 2 can be confirmed through the detection circuit. Moreover, by setting the fixed resistance resistor, each paired sensor 1 and transmitter 2 also has a detectable fixed current value, and the conduction state of the detection circuit can be accurately verified through this fixed current to confirm the connection state of the sensor 1 and the transmitter 2.

[0033] At the same time, such as Figure 10As shown, the detection circuit is also provided with a voltage detection chip. The voltage detection chip can independently measure the voltage change in the detection circuit. Taking the resistance value of a fixed-resistance resistor as 1 kΩ and the normal current magnitude in the detection circuit as 0.1 mA as an example, when the sensor 1 and the transmitter 2 are normally connected, the voltage in the detection circuit is 0.1 V. When the connection between the sensor 1 and the transmitter 2 is abnormal or there is poor contact, the detection circuit also has poor contact. At this time, the voltage in the detection circuit will be close to 0 V or be the battery voltage (such as 1.5 V of a button battery). By setting the voltage detection chip, the impedance between the first detection element 31 and the second detection element 32 can be detected, so as to confirm that the detection circuit maintains a normal conduction state, and can form a dual-channel detection with the current detection chip to improve the redundancy performance of the detection circuit and ensure that the detection circuit detects the connection state of the sensor 1 and the transmitter 2 in real time to ensure the stability and continuity of the connection between the sensor 1 and the transmitter 2.

[0034] Meanwhile, one of the first detection element 31 and the second detection element 32 can be a magnetic part, and the other of the first detection element 31 and the second detection element 32 is a Hall sensor. The detection circuit formed by the first detection element 31 and the second detection element 32 can be a magnetic circuit loop. Of course, the Hall sensor is electrically connected to the second circuit board 212. The magnetic circuit loop formed by the detection circuit can cause the Hall sensor to generate an induced current and transmit the induced current to the second circuit board 212 to realize the detection of the connection state of the sensor 1 and the transmitter 2, so as to facilitate the user to confirm that the transmitter 2 and the sensor 1 are in an accurate and stable connection state at this time.

[0035] It can be understood that by respectively arranging the first detection element 31 and the second detection element 32 on the transmitter 2 and the sensor 1, when the transmitter 2 and the sensor 1 are connected to each other, that is, in a connected state, the first detection element 31 and the second detection element 32 generate a detection circuit, so that the circuit connection and conduction of the first conductive part 12 and the second conductive part 22 can be determined through the detection circuit, so as to determine the stable connection between the transmitter 2 and the sensor 1 and improve the accuracy and continuity of the blood glucose detection device 100 during detection.

[0036] In an embodiment, as Figures 1 to 5 shown, the sensor body 11 includes a substrate 111 and a mounting seat 112. The substrate 111 is detachably connected to the transmitter body 21. The mounting seat 112 is arranged on the substrate 111, and the first conductive part 12 is arranged on the mounting seat 112; the first detection element 31 or the second detection element 32 is arranged on the substrate 111, and the first detection element 31 or the second detection element 32 is arranged around the mounting seat 112.

[0037] In this embodiment, the sensor body 11 includes a substrate 111 and a mounting base 112. The substrate 111 is the main structure of the sensor body 11, which is in a plate-like structure and has a mounting surface 1111. The mounting base 112 is provided on the mounting surface 1111 of the substrate 111. At the same time, the mounting base 112 is provided with a bottom groove, and the bottom groove formed by the mounting base 112 extends in a direction perpendicular to the plate surface of the substrate 111. The first conductive member 12 is disposed in the bottom groove of the mounting base 112.

[0038] Among them, the mounting base 112 protrudes from the surface of the substrate 111, that is, the mounting base 112 itself has a certain height, so that the bottom groove formed by the mounting base 112 has a height in a direction perpendicular to the plate surface of the substrate 111. The transmitter 2 further includes a circuit board 212. The circuit board 212 is disposed in the transmitter body 21, and the second conductive member 22 is electrically connected to the circuit board 212. At least a part of the circuit board 212 abuts against the mounting base 112 and seals the notch of the bottom groove. For example, all of the circuit board 212 is disposed on the mounting base 112 and seals the notch of the bottom groove, or a part of the circuit board 212 is disposed on the mounting base 112 and seals the notch of the bottom groove, so that the second conductive member 22 abuts against the first conductive member 12 and the first conductive member 12 and the second conductive member 22 are electrically connected.

[0039] At the same time, the first detection member 31 or the second detection member 32 in the detection assembly 3 is disposed on the substrate 111 and is disposed around the mounting base 112. For example, the first detection member 31 is disposed on the substrate 111, the second detection member 32 is disposed on the circuit board 212, and at the same time, the first detection member 31 is disposed around the mounting base 112. The first detection member 31 may be an annular conductive strip or a plurality of conductive members to be disposed around the mounting base 112.

[0040] It can be understood that by disposing the first detection member 31 (or the second detection member 32) around the mounting base 112, when the transmitter 2 is connected to the sensor 1, the first detection member 31 around the mounting base 112 is electrically connected to each second detection member 32, so that it is possible to confirm whether the circuit board 212 and the substrate 111 are kept horizontal at this time through the pairing connection situation between each first detection member 31 and the second detection member 32, so as to confirm whether the connection between the transmitter 2 and the sensor 1 is in place. For example, when the second detection member 32 and the first detection member 31 around the mounting base 112 are both electrically connected to form a detection circuit, it can be confirmed that the first conductive member 12 and the second conductive member 22 are in a stable connection state to ensure the accuracy and continuity of the blood glucose detection device 100 during detection.

[0041] In one embodiment, such as Figures 2 to 5As shown, the detection component 3 includes at least two first detection elements 31 and at least two second detection elements 32. Each of the first detection elements 31 is electrically connected, and each of the second detection elements 32 is electrically connected. In the connected state, each first detection element 31 is electrically connected to a detection element to form a detection circuit; each of the first detection elements 31 or each of the second detection elements 32 is at least disposed on opposite sides of the mounting base 112.

[0042] It can be understood that each of the first detection elements 31 is connected in series in sequence, and each of the second detection elements 32 is connected in series in sequence. In the connected state, each first detection element 31 is in electrical contact with a second detection element 32 and the circuit is turned on, thereby forming a detection circuit. Moreover, each of the first detection elements 31 or each of the second detection elements 32 disposed on the substrate 111 is at least located on opposite sides of the mounting base 112 and is spaced apart from the mounting base 112. In the connected state, the second conductive member 22 in the transmitter 2 is in contact with and the circuit is turned on with the first conductive member 12 disposed in the mounting base 112. Based on the fact that each of the first detection elements 31 (or each of the second detection elements 32) on the periphery of the mounting base 112 is in contact with each of the second detection elements 32 (or each of the first detection elements 31) and forms a detection circuit, it indicates that both the transmitter 2 and the sensor 1 are properly installed at this time, and the first conductive member 12 and the second conductive member 22 also achieve stable circuit conduction, thereby ensuring the stable and continuous operation of the blood glucose detection device 100.

[0043] In one embodiment, one of the first detection element 31 and the second detection element 32 is one of a conductive capsule, a conductive spring, and a conductive probe, and the other of the first detection element 31 and the second detection element 32 is a conductive terminal.

[0044] In this embodiment, the transmitter 2 further includes a circuit board 212. Taking the first detection element 31 as a conductive capsule or a conductive probe or a conductive spring and the second detection element 32 as a conductive terminal as an example, the conductive capsule is limitedly disposed on the substrate 111 of the sensor 1, the conductive terminals are disposed on the circuit board 212, and the electrical connection of each conductive terminal is achieved through the circuit board 212. One ends of the conductive capsules are electrically connected to each other, such as through a first circuit board 15, gold wires, and welding, etc. In the connected state, the other ends of the conductive capsules are respectively in electrical contact with a conductive terminal to achieve the circuit conduction between the first detection element 31 and the second detection element 32, thereby forming a detection circuit.

[0045] It can be understood that the conductive capsule has good flexibility and elasticity, enabling it to adapt to the irregular surface of the circuit board 212, especially the contact part in contact with the circuit board 212, ensuring that the conductive capsule can always abut against the relevant contact part of the circuit board 212, ensuring stable electrical contact. Moreover, through its own flexibility and elasticity, the conductive capsule can effectively absorb the vibration and impact generated externally, maintain a stable elastic abutment with the circuit board 212, ensure a stable electrical connection of the signal transmission device during the daily activities and movements of the user, reduce and avoid possible poor contact phenomena, and ensure that the first detection piece 31 and the second detection piece 32 are always in a stable circuit conduction to ensure the real-time detection of the first conductive piece 12 and the second conductive piece 22, thereby ensuring the stable operation of the blood glucose meter. Further, based on the flexibility and elasticity of the conductive capsule itself, it can generate a larger contact area through its own elastic deformation, making it have a smaller contact resistance and improving the conductive performance. During the frequent abutment and compression of the sensor 1, it also has better anti-fatigue performance.

[0046] In one embodiment, as Figure 2 shown, the substrate 111 has a length direction and a width direction, and the length direction is greater than the width direction. The mounting seat 112 is provided at one end of the substrate 111 along the length direction; the sensor 1 further includes a positioning post 13, and the positioning post 13 is provided at the other end of the substrate 111 along the length direction. The transmitter main body 21 is provided with a positioning groove 2111. In the connected state, the positioning post 13 is limited in the positioning groove 2111.

[0047] In this embodiment, the substrate 111 of the blood glucose detection device 100 has a length direction and a width direction that are perpendicular to each other. Since the sensor 1 in the blood glucose detection device 100 is worn or attached closely to the body, such as worn on the user's arm or abdomen, etc., in order to adapt to ergonomics, such as the human arm extending longitudinally or the human abdomen extending transversely, etc., the substrate 111 in the sensor 1 is set to have a larger size in the length direction than in the width direction, that is, the substrate 111 of the sensor 1 extends in a long strip shape, so that it has a long side and a short side, enabling it to be arranged along the longitudinal extension direction of the arm or the transverse extension direction of the abdomen when the sensor 1 is attached to the user's arm or abdomen. On the one hand, it can ensure that the sensor 1 has a larger detection area, on the other hand, it can also ensure the firmness of the wearing and bonding of the sensor 1, and at the same time improve the comfort of the user.

[0048] Meanwhile, the transmitter 2 detachably connected to the sensor 1 has its housing 211 correspondingly set to have a dimension in the length direction greater than that in the width direction, so as to be adapted to the sensor 1. Also, the sensor body 11 can also adopt a bilateral detachable connection. In the width direction with a smaller length, the user can hold the housing 211 with one hand, enabling one-handed operation to achieve the disassembly and assembly of the transmitter 2 and the sensor 1, and allowing for quick disassembly and assembly without precise docking.

[0049] Furthermore, the sensor 1 further includes at least one positioning post 13. The positioning post 13 is provided on the mounting surface 1111 of the substrate 111, and the column body of the positioning post 13 extends in a direction away from the mounting surface 1111 along a direction perpendicular to the mounting surface 1111, so that the mounting post protrudes from the mounting surface 1111. At least one positioning groove 2111 corresponding to the positioning post 13 is provided on the transmitter body 21, such as the positioning groove 2111 is provided on the side of the housing 211 of the transmitter body 21 facing the substrate 111.

[0050] It can be understood that the above-mentioned mounting seat 112 can be provided at one end of the substrate 111 along the length direction, and the positioning post 13 is provided at the other end of the substrate 111 along the length direction, that is, the mounting seat 112 and the positioning post 13 are spaced apart at both ends of the substrate 111 along the length direction. When the user connects the transmitter 2 to the sensor 1, the first conductive member 12 and the second conductive member 22 can be first positioned through the mounting seat 112 at one end to achieve mechanical connection and circuit conduction. Then, the positioning post 13 at the other end and the positioning groove 2111 are further inserted into each other. Through the positioning connection between the substrate 111 of the sensor 1 and the housing 211 of the transmitter 2, the accurate fixation and positioning of the first conductive member 12 and the second conductive member 22 are realized, ensuring the stability of the circuit conduction between the first conductive member 12 and the second conductive member 22, and thus guaranteeing the accuracy and continuity of the blood glucose detection device 100 during detection.

[0051] Of course, the mounting seat 112 can be not only provided at the end position of the substrate 111 along the length direction, but also at any intermediate position of the substrate 111. At the same time, the positioning post 13 can be spaced from the mounting seat 112 along the length direction, or can be arranged around the mounting seat 112. For example, the positioning post 13 is provided on both sides of the mounting seat 112 along the length direction, so as to ensure the stability of the connection between the first conductive member 12 in the sensor 1 and the second conductive member 22 in the transmitter 2 through the insertion and positioning of the positioning post 13 and the positioning groove 2111.

[0052] Optionally, the emitter body 21 is further provided with a first magnetic member, and the substrate 111 is provided with a second magnetic member. In the connected state, the first magnetic member and the second magnetic member are magnetically connected. It can be understood that the first magnetic member is provided on the emitter body 21, that is, the housing 211, and the second magnetic member is provided on the substrate 111. In the connected state, the first magnetic member and the second magnetic member are magnetically attracted to each other. On the one hand, it ensures that the first conductive member 12 and the second conductive member 22 are quickly positioned and the circuit is conducted, and the positioning post 13 is quickly positioned in the positioning groove 2111, improving the convenience of the user for alignment and installation with one hand and in the case where direct visual inspection is not possible. At the same time, on the other hand, it can also improve the connection firmness between the emitter 2 and the sensor 1, reduce the misalignment and displacement generated during the installation of the two, and further ensure the stability of the electrical connection and circuit conduction between the first conductive member 12 and the second conductive member 22.

[0053] In one embodiment, as Figure 4 and Figure 5 shown, the sensor body 11 further includes a support plate 16, a first circuit board 15 and an adhesive tape 17. The support plate 16 is provided on the side of the substrate 111 facing away from the mounting seat 112. The first circuit board 15 includes a detection end 151 and a conduction end 153. The detection end 151 and the conduction end 153 are connected. The detection end 151 is provided on the side of the support plate 16 facing away from the substrate 111. The detection end 151 is configured to abut against the user's skin and obtain the glucose content in the user's tissue fluid. The conduction end 153 is provided on the side of the support plate 16 facing the substrate 111. The conduction end 153 is electrically connected to the first conductive member 12. The adhesive tape 17 is annularly provided on the substrate 111. The adhesive tape 17 surrounds the first circuit board 15.

[0054] In this embodiment, the sensor 1 includes a support plate 16 and a first circuit board 15. The support plate 16 is used to mount and place the first circuit board 15. The support plate 16 has a plate-like or sheet-like structure. Mounting surfaces 1111 are provided on both sides of the support plate 16 having the largest plate surface area. The two mounting surfaces 1111 face away from each other. At the same time, a guiding surface is also provided on the support plate 16. The guiding surface is located between the two mounting surfaces 1111. The guiding surface is connected to the two mounting surfaces 1111.

[0055] Further, the first circuit board 15 can be the first circuit board 15, which includes a detection end 151, a conduction end 153, and a connection section 152. The connection section 152 is located between the detection end 151 and the conduction end 153, and the connection section 152 is connected to and electrically conductive with the detection end 151 and the conduction end 153. Among them, the detection end 151 is provided on one mounting surface 1111 of the support plate 16 for contacting the user's skin and performing blood glucose detection. The conduction end 153 is provided on the other mounting surface 1111 of the support plate 16. The connection section 152 is provided on the guiding surface. The conduction end 153 is used to be electrically connected to the transmitter 2. The connection section 152 transmits the blood glucose data detected by the detection end 151 to the transmitter 2 through the conduction end 153, and then transmits it to an external signal receiving device through the transmitter 2, so that the user can understand the current blood glucose data in real time.

[0056] It can be understood that the guiding surface is preferably an arc-shaped curved surface, and the guiding surface can be provided on the periphery of the support plate 16 or in the internal structure of the support plate 16. For example, a groove is opened inside the support plate 16. By setting the guiding surface to guide the extension of the connection section 152, the connection section 152 can naturally and continuously extend from one mounting surface 1111 to the other mounting surface 1111, reducing the bending degree of the connection section 152 during the corner process, thereby reducing the overall breakage risk of the connection section 152 and the first circuit board 15, extending the service life of the first circuit board 15, the sensor 1, and the blood glucose detector. At the same time, the guiding surface can reduce the friction and damage suffered by the first circuit board 15 during the installation process and extend its service life.

[0057] In this embodiment, the sensor body 11 further includes an adhesive tape 17. The adhesive tape 17 is provided on the periphery of the substrate 111 and is arranged around the substrate 111, that is, located at the periphery of the substrate 111. A hollow portion 171 is provided in the center of the adhesive tape 17, and the first circuit board 15 is located at the hollow portion 171. The extension plane of the adhesive tape 17 is substantially parallel to the user's skin. By providing the adhesive tape 17, the sensor 1 can be fixed to the user's skin surface, so that the detection electrode can contact the user's skin as much as possible for blood glucose detection, improving the overall fit between the sensor 1 and the detection electrode provided on the sensor 1 and the user's skin. At the same time, it can also reduce the deformation of the detection section caused by the changes in the user's skin and muscles, reduce the risk of breakage of the first circuit board 15, and extend the service life of the first circuit board 15 and the sensor 1.

[0058] In one embodiment, as Figures 6 to 8 shown, the transmitter body 21 includes a housing 211 and a button 213. The button 213 is elastically connected to the housing 211. The button 213 includes a connected button portion 2132 and a clamping portion 2133. The sensor main body 11 further includes a substrate 111 and a clamping member 14. The clamping member 14 is provided on the substrate 111, and the button portion 2132 is configured to drive the clamping portion 2133 to move closer to or away from the clamping member 14 by pressing.

[0059] In this embodiment, the button 213 includes a bearing portion 2131, a button portion 2132, a clamping portion 2133, and an elastic member 2134. The bearing portion 2131 of the button 213 is provided on the housing 211. The bearing portion 2131 is the main body support structure of the button 213 for installing the button portion 2132. Among them, the bearing portion 2131 can be structures such as a mounting bracket, a mounting table, the sensor main body 11, etc., which are not limited herein.

[0060] The clamping portion 2133 and the elastic member 2134 are connected to the button portion 2132. Among them, the clamping portion 2133 is slidably connected to the bearing portion 2131. For example, if one of the bearing portion 2131 and the clamping portion 2133 is provided with structures such as a guide groove, a sliding groove, a sliding sleeve, etc., and the other of the bearing portion 2131 and the clamping portion 2133 is a guide post, a guide bar, a guide block, a shaft, a roller, etc., the above-mentioned guide post, guide bar, guide block, shaft, roller can extend into the guide groove, sliding groove, sliding sleeve to realize the sliding connection between the bearing portion 2131 and the clamping portion 2133; the elastic member 2134 is elastically connected to the bearing portion 2131, and the elastic member 2134 can be elastically connected to the bearing portion 2131 through elastic structures such as a spring, a spring piece, an elastic body, etc. When the user presses the button portion 2132, the elastic structure between the elastic member 2134 and the bearing portion 2131 generates elastic deformation. At the same time, the clamping portion 2133 slides relative to the bearing portion 2131, so that the overall position of the button portion 2132 changes, thereby realizing the connection or separation with the buckle or card slot in the external device (such as the sensor 1).

[0061] Furthermore, the button 213 includes at least two elastic members 2134, and each elastic member 2134 is arranged in central symmetry around the clamping portion 2133. That is, each elastic member 2134 is located around the clamping portion 2133 and is evenly spaced with the clamping portion 2133 as the center. For example, the button portion 2132 includes two elastic members 2134, and the two elastic members 2134 are located on both sides of the clamping portion 2133 and are symmetrically arranged with the clamping portion 2133 as the center. At this time, the button portion 2132 is arranged in a long strip structure, the two elastic members 2134 are located at both ends, and the clamping portion 2133 is located in the middle; or the button portion 2132 includes four elastic members 2134, and the four elastic members 2134 are located around the clamping portion 2133 and are symmetrically spaced with the clamping portion 2133 as the center. At this time, the button portion 2132 is arranged in a circular or square structure.

[0062] It can be understood that the sensor 1 is attached to the user's arm or abdomen. The user usually operates the button 213 with one hand to separate or connect the transmitter 2 from the sensor 1. Moreover, it is not convenient for the user to visually observe the position of the button 213. Usually, the position of the button 213 is directly located by touch and directly pressed to separate or connect the transmitter 2 from the sensor 1. When pressing, by arranging the elastic members 2134 around the clamping portion 2133 in a centrosymmetric manner, the stability and balance of the connection between the button portion 2132 and the bearing portion 2131 can be maintained. No matter whether the user presses a certain local position, end, side or other extreme positions of the button portion 2132, the clamping portion 2133 located in the middle of the elastic member 2134 can be driven to slide relative to the bearing portion 2131 together, so as to realize the precise change of the position of the button portion 2132 relative to the bearing portion 2131, reduce the probability of skew and jamming that may occur when the button portion 2132 is pressed, improve the stability and smoothness when the button portion 2132 moves relative to the bearing portion 2131, and improve the convenience and comfort during the user's direct touch operation.

[0063] The button 213 in this embodiment includes a bearing portion 2131, a button portion 2132, a clamping portion 2133 and an elastic member 2134. The bearing portion 2131 is the main support structure of the button 213 and is used to support the button portion 2132. The button portion 2132 includes a clamping portion 2133 and at least two elastic members 2134. The clamping portion 2133 is slidably connected to the bearing portion 2131, and the elastic member 2134 is elastically connected to the bearing portion 2131 and the button portion 2132. The elastic members 2134 are arranged around the clamping portion 2133 in a centrosymmetric manner. By arranging the elastic members 2134 elastically connected to the bearing portion 2131 around the clamping portion 2133, stable support can be generated by the surrounding elastic members 2134, ensuring the smoothness and stability when the clamping portion 2133 slides relative to the bearing portion 2131, thereby improving the stability and smoothness when the button portion 2132 moves relative to the bearing portion 2131, reducing jamming caused by uneven force, and improving the user experience.

[0064] At the same time, the clamping portion 2133 can be engaged with the engaging member 14 to realize the detachable connection between the sensor 1 and the transmitter 2. When the sensor 1 and the transmitter 2 are connected to each other, by pressing the button portion 2132 of the button 213, the clamping portion 2133 is connected to or separated from the engaging member 14. For example, two buttons 213 are provided. By pressing the two buttons 213, relative movement is generated between the two buttons 213 to change the relative distance therebetween, so that the engaging member 14 extends into the clamping portion 2133 and is engaged with the clamping portion 2133. The engaging member 14 can be an inverted hook-shaped hook, or a convex or limiting convex structure, etc., so that the engaging member 14 limits the button 213 to maintain the mutual connection between the engaging member 14 and the button 213, thereby realizing the mutual connection between the sensor 1 and the transmitter 2.

[0065] By providing two oppositely arranged buttons 213, on the one hand, the user needs to press the two buttons 213 simultaneously to unlock the sensor 1 and the transmitter 2, avoiding the single button 213 being easily triggered during daily use and causing the abnormal detachment of the sensor 1 and the transmitter 2, reducing the risk of loss and damage of the transmitter 2 or the sensor 1. On the other hand, it also facilitates the user to operate the two buttons 213 with one hand. For example, the two buttons 213 can be pressed simultaneously with two fingers, effectively improving the convenience and stability during one-handed operation.

[0066] In another embodiment of the present invention, the button portion 2132 is provided with a pressing surface, and the user presses the button portion 2132 and the button 213 by contacting the pressing surface. The pressing surface can be a curved surface, such as a curved surface with both ends protruding and the middle concave, to facilitate the user's quick positioning, or it can be an inclined surface to facilitate the user to hold the button 213 with both hands and press it quickly.

[0067] In one embodiment, as Figures 2 to 7 shown, the sensor main body 11 includes at least two clamping members 14, and each clamping member 14 is respectively arranged at two opposite side edges of the substrate 111; the transmitter main body 21 includes at least two buttons 213, and each button 213 is respectively arranged at two opposite side edges of the housing 211, and each button 213 is arranged corresponding to one clamping member 14.

[0068] In this embodiment, the sensor main body 11 includes at least two clamping members 14. At the same time, the substrate 111 has two opposite side edges. For example, the substrate 111 is a plate-like or sheet-like structure, and the extending directions of the two opposite side edges are substantially the same. Among them, each clamping member 14 is respectively arranged at the two opposite side edges of the substrate 111, so that the clamping members 14 located on the two opposite side edges are oppositely arranged along the width direction or along a direction forming an angle with the width direction. At the same time, the transmitter main body 21 includes at least two buttons 213. The extending directions of the edges of the housing 211 are substantially consistent, so that the housing 211 also has two oppositely arranged edges. The two buttons 213 are arranged corresponding to the clamping members 14 at the two oppositely arranged edges of the housing 211, and each button 213 is clamped with at least one clamping member 14 on one side edge, and the two buttons 213 are simultaneously clamped with the clamping members 14 located on the two opposite edges.

[0069] Among them, the clamping member 14 is a structure such as a hook or a column. The button 213 is elastically connected to the housing 211, and the button 213 is provided with a bayonet or a clamping groove for clamping with the clamping member 14. When the user presses the button 213, the bayonet of the button 213 is connected to or separated from the clamping member 14.

[0070] It can be understood that the two buttons 213 are respectively arranged at two opposite side edges of the housing 211, so that the two buttons 213 can be arranged at a relative interval. Correspondingly, the clamping members 14 are also arranged at two opposite edges of the substrate 111, so that each button 213 can be clamped with one or more clamping members 14 at the same time. The two buttons 213 can realize the detachable connection with the respective clamping members 14, so as to realize the mutual connection and separation of the transmitter 2 and the sensor 1.

[0071] Among them, when the user is inconvenient to operate with both hands and is inconvenient to directly visually observe the position of the button 213, the user can directly use the thumb and index finger of one hand to quickly (other fingers can also be used, only taking the thumb and index finger as an example, which is not limited here) locate the two opposite side edges of the housing 211, so as to quickly locate the button 213, and by pressing the buttons 213 at the same time, the detachment or connection of each button 213 with the corresponding clamping member 14 can be realized, 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 the operation.

[0072] At the same time, the clamping members 14 are respectively arranged at two opposite side edges of the substrate 111, which can also ensure that the housing 211 on the transmitter main body 21 can be accurately and tightly connected to the substrate 111 on the sensor main body 11, that is, the mechanical connection between the sensor 1 and the transmitter 2 is accurate and firm, so as to ensure that the alignment electrical contact between the first conductive member 12 and the second conductive member 22 is accurate and stable, and make the detection process of the blood glucose detection device 100 more accurate and stable.

[0073] In an embodiment, as Figure 7 shown, the transmitter main body 21 further includes a bottom plate 23 and a second circuit board 212. The bottom plate 23 is connected to the housing 211, and the second circuit board 212 is arranged on the bottom plate 23 and is located between the bottom plate 23 and the housing 211; In the connected state, the bottom plate 23 abuts against the substrate 111, the bottom plate 23 and the substrate 111 are arranged in parallel, one end of the second conductive member 22 abuts against the first conductive member 12 and is electrically connected in a circuit, and the other end of the second conductive member 22 abuts against the second circuit board 212 and is electrically connected in a circuit.

[0074] In this embodiment, the bottom plate 23 is a structural support member of the transmitter main body 21, which can be a support structure such as a base frame, a mounting frame, a base, a bottom plate 23, etc. A bottom groove is provided on the bottom plate 23, and the bottom groove has a certain depth and edge. The bottom groove can be opened on the plate body of the bottom plate 23, that is, the notch of the bottom groove is located on the plate surface of the bottom plate 23, or a mounting seat 112 or a mounting table can be arranged on the bottom plate 23, and a bottom groove is arranged on the mounting seat 112 or the mounting table, and the notch of the bottom groove has a certain distance from the plate surface of the bottom plate 23, which is not limited here.

[0075] Furthermore, the second circuit board 212 is also disposed on the bottom plate 23. On the basis of providing the bottom groove, at least a part of the second circuit board 212 hermetically covers the notch of the bottom groove, so that the second circuit board 212 and the bottom groove jointly enclose a sealed installation cavity. For example, a sealing protrusion is provided on one of the notch of the bottom groove and the side of the second circuit board 212 covering the bottom groove, and a sealing groove is provided on the other of the notch of the bottom groove and the side of the second circuit board 212 covering the bottom groove. Through the tight fit between the sealing groove and the sealing protrusion, the installation cavity is well sealed. At the same time, sealing members such as sealing silica gel, sealing rings, and sealants can also be provided in the sealing groove to further improve the sealing performance.

[0076] Among them, at least a part of the second conductive member 22 is disposed in the installation cavity, and one end of the second conductive member 22 directly abuts against the second circuit board 212 in the installation cavity and is electrically connected to the second circuit board 212, and the other end of the second conductive member 22 is electrically abutted against the first conductive member 12.

[0077] It can be understood that on the one hand, the second conductive member 22 leads out the conductive end points of the second circuit board 212, so that the first conductive member 12 can realize the circuit connection with the second circuit board 212 by electrically abutting against the second conductive member 22, thereby realizing the stable circuit connection between the sensor 1 and the transmitter 2. Moreover, through the abutment between the second conductive member 22 and the second circuit board 212, the stability of the circuit connection between the second conductive member 22 and the second circuit board 212 can be effectively improved, thereby ensuring the stability of the circuit connection between the sensor 1 and the transmitter main body 21, avoiding possible virtual connection and poor contact, and effectively improving the detection continuity and detection accuracy of the blood glucose meter.

[0078] Among them, the second conductive member 22 can be an elastic conductive member, such as a conductive capsule. The conductive capsule has good flexibility and elasticity, so that the second conductive member 22 can adapt to the irregular surface of the second circuit board 212, especially the contact part in contact with the second circuit board 212, ensuring that the second conductive member 22 can always abut against the relevant contact part of the second circuit board 212 and ensuring stable electrical contact. Moreover, through its own flexibility and elasticity, the second conductive member 22 can effectively absorb the vibration and impact generated by the outside world, maintain a stable elastic abutment with the second circuit board 212, ensure stable electrical connection of the transmitter main body 21 during the daily activities and movements of the user, reduce and avoid possible poor contact phenomena, and ensure the stable operation of the blood glucose meter. Further, based on the flexibility and elasticity of the second conductive member 22 itself, it can generate a large contact area through its own elastic deformation, so that it has a smaller contact resistance, improves the conductive performance, and also has better anti-fatigue performance during the frequent abutment and compression of the sensor 1.

[0079] It can be understood that when the transmitter 2 and the sensor 1 are connected to make the blood glucose detection device 100 in a connected state, the bottom plate 23 in the transmitter 2 abuts against the substrate 111 in the sensor 1, and the plate surface of the bottom plate 23 and the plate surface of the substrate 111 are kept parallel, so that the transmitter 2 and the sensor 1 are closely attached. Moreover, the first conductive member 12 can extend in a direction perpendicular to the plate surface of the substrate 111, and the second conductive member 22 can extend in a direction perpendicular to the plate surface of the bottom plate 23. In the connected state, the end of the first conductive member 12 and the end of the second conductive member 22 directly abut against each other to realize circuit conduction, so as to ensure the effective circuit conduction between the sensor 1 and the transmitter 2.

[0080] In one embodiment, as Figure 2 and Figure 6 shown, the sensor body 11 further includes a limiting member 113. The limiting member 113 is arranged at the end of the substrate 111 along the length direction and is located between the clamping members 14. The limiting member 113 and the clamping members 14 are arranged around the mounting seat 112; the housing 211 is also provided with a limiting groove 2112. In the connected state, the limiting member 113 is limited in the limiting groove 2112.

[0081] In this embodiment, the substrate 111 further has an intermediate edge connecting the two side edges. The intermediate edge and the side edges together form the boundary of the housing 211. The limiting member 113 is arranged at the intermediate edge and makes the limiting member 113 located between two relatively arranged clamping members 14. At the same time, the housing 211 is provided with a limiting groove 2112 in the middle of the side edge. When the sensor 1 and the transmitter 2 are connected to each other, the limiting member 113 is limited in the limiting groove 2112.

[0082] It can be understood that when the user disassembles the sensor 1 and the transmitter 2, after the user presses the buttons 213 on both sides in a clamping manner, the limiting member 113 still remains in the limiting groove 2112. Therefore, the connection relationship between the limiting member 113 and the transmitter body 21 is still retained, avoiding the direct separation of the sensor 1 and the transmitter 2. Or when the user accidentally touches the button 213, causing an abnormal separation between the button 213 and the clamping member 14, the sensor 1 and the transmitter 2 are still connected to each other through the limiting member 113, thus avoiding the direct separation of the transmitter 2 from the sensor 1, reducing the risk of loss and damage of the transmitter 2. Moreover, arranging the limiting member 113 between two relatively arranged clamping members 14 does not affect the normal connection and disassembly of the clamping member 14 and the button 213. At the same time, each limiting member 113 cooperates with the clamping member 14. While the clamping member 14 is clamped with the button 213, the limiting member 113 can also connect and limit the edges of the sensor 1 and the transmitter 2, thus ensuring the stability of the connection between the transmitter 2 and the sensor 1.

[0083] It can be understood that the snap connector 14 and the limiting member 113 play different roles. Among them, the snap connector 14 is used to connect with the button 213. For example, a card slot or a card hole that is snap-connected to the snap connector 14 is provided in the button 213, so as to realize the detachable connection between the snap connector 14 and the button 213, thereby realizing the detachable connection between the transmitter 2 and the sensor 1. At the same time, the limiting member 113 is connected to the transmitter main body 21 or the sensor main body 11 in a limiting manner. For example, a limiting groove 2112 is provided on the transmitter main body 21 or the sensor main body 11, and the limiting member 113 can extend into the limiting groove 2112 and be in limiting abutment and / or limiting snap connection with the limiting groove 2112. The limiting member 113 can limit the transmitter 2 and the sensor 1 to maintain a tight connection between the sensor 1 and the transmitter 2, so as to compensate for the connection gap between the snap connector 14 and the button 213. By providing the snap connector 14 and the limiting member 113, on the basis of realizing the detachable connection between the sensor 1 and the transmitter 2, the tight connection between the transmitter 2 and the sensor 1 can be maintained, that is, the stable connection of the circuit conduction structure between the transmitter 2 and the sensor 1 is ensured, and the possible virtual positions and gaps caused by only setting the snap connector 14 are avoided, so as to ensure the continuity, stability and detection accuracy of the blood glucose detection device 100 during operation.

[0084] At the same time, when the user accidentally touches the button 213, causing the button 213 and the snap connector 14 to be abnormally disengaged, the sensor 1 and the transmitter 2 are still connected to each other through the limiting member 113, thereby preventing the transmitter 2 from directly detaching from the sensor 1 and reducing the risk of loss and damage of the transmitter 2.

[0085] Moreover, in the connected state, the limiting member 113 and the snap connector 14 are arranged around the mounting seat 112, so as to facilitate the disassembly and assembly of the sensor 1 and the transmitter 2, and at the same time, the alignment accuracy and connection stability between the first conductive member 12 and the second conductive member 22 can be improved through the limiting member 113.

[0086] In one embodiment, as Figure 9 and Figure 10 shown, the blood glucose detection device 100 further includes an authentication component. The authentication component includes a signal transmitter and a signal receiver. One of the signal transmitter and the signal receiver is arranged on the transmitter main body 21, and the other of the signal transmitter and the signal receiver is arranged on the sensor main body 11; the signal transmitter and the signal receiver are communicatively connected.

[0087] In this embodiment, the authentication component includes a signal transmitter and a signal receiver. The signal transmitter and the signal receiver are respectively disposed on the transmitter 2 and the sensor 1. That is, based on the blood glucose detection device 100 having a separable structure for the transmitter 2 and the sensor 1, the authentication component is respectively provided on the transmitter 2 and the sensor 1. Taking the example of setting a signal transmitter on the sensor 1 and a signal receiver on the transmitter 2, when the transmitter 2 is connected to the sensor 1, that is, when the blood glucose detection device 100 is in a connected state, the signal receiver receives the signal emitted by the signal transmitter, and the signal transmitter and the signal receiver authenticate each other to achieve pairing and authentication between the transmitter 2 and the sensor 1. Of course, it is also possible to set a signal receiver on the sensor 1 and a signal transmitter on the transmitter 2 to achieve pairing and authentication between the transmitter 2 and the sensor 1, which is not limited herein.

[0088] It can be understood that by setting the signal transmitter and the signal receiver, the current connection state of the transmitter 2 and the sensor 1 can be monitored in real time through the signal strength and the error rate between the signal transmitter and the signal receiver. When the signal strength is lower than the threshold or the error rate exceeds the limit, an alarm is triggered, indicating that there is a loose connection or disconnection in the circuit conduction between the transmitter 2 and the sensor 1 at this time, that is, the circuit connection between the first conductive member 12 and the second conductive member 22 is unstable, thereby effectively improving the stable connection between the transmitter 2 and the sensor 1 and enhancing the accuracy and continuity of the blood glucose detection device 100 during detection.

[0089] Meanwhile, by setting the signal transmitter and the signal receiver, it is ensured that only authorized sensors 1 and transmitters 2 can be paired and used, preventing misconnection between the transmitter 2 and the sensor 1, such as interference between the transmitters 2 and the sensors 1 in multiple blood glucose detection devices 100, which may cause errors and impacts on the detection results; and, after the transmitter 2 is separated from the sensor 1 by a certain distance, the position of the transmitter 2 can also be conveniently understood by the user through the signal connection between the signal transmitter and the signal receiver.

[0090] In one embodiment, the signal transmitter is a Bluetooth transmitter, and the signal receiver is a Bluetooth receiver; or, the signal transmitter is an ultrasonic generator, and the signal receiver is a microphone receiver; or, the signal transmitter is an NFC transmitter 2, and the signal receiver is an NFC receiver.

[0091] In this embodiment, the signal transmitter may be an integrated low-power Bluetooth chip, and the signal receiver is a low-power Bluetooth receiving module. Using a Bluetooth transmitter and a Bluetooth receiver has the beneficial effects of ultra-low power consumption and wide-area compatibility. Alternatively, the signal transmitter is an ultrasonic generator, the ultrasonic generator is a piezoelectric ceramic ultrasonic generator, the signal receiver is a highly sensitive MEMS microphone. The ultrasonic generator transmits a modulated ultrasonic pulse sequence to the MEMS microphone. The MEMS microphone converts the analog signal into an electrical signal after receiving the ultrasonic pulse and outputs relevant data to achieve signal transmission. By setting the ultrasonic generator and the microphone receiver, it can be free from radio frequency interference and is suitable for strong electromagnetic environments such as the ICU, effectively improving the versatility and adaptability of the blood glucose detection device 100. Or the signal transmitter is an NFC tag, and the signal receiver is an NFC card reader. When the transmitter 2 and the sensor 1 are connected to each other, the NFC tag obtains energy and is awakened after entering the magnetic field range of the NFC card reader. The card reader verifies the digital signature and then transmits a confirmation instruction back to achieve the pairing and authentication of both the sensor 1 and the transmitter 2. By setting NFC authentication, the authentication time is fast and the power consumption is low, improving the usability.

[0092] The above are only exemplary embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied to other related technical fields, is included in the patent protection scope of the present invention.
