Currently, conventional blood glucose detection is usually invasive, that is, it is necessary to puncture and collect peripheral blood, and then process the blood to obtain the blood glucose value. Detecting blood glucose values by puncturing and collecting blood will cause harm to the body of the tested person.

[0048] The embodiments of the present application first provide a blood glucose detection system. Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of a blood glucose detection system provided by the embodiments of the present application. As Figure 1 shown, the blood glucose detection system may include a blood glucose detection device 11, a first device 12 and a server 13.

[0049] Among them, the first device 12 may be wirelessly connected to the blood glucose detection device 11, and the first device 12 may be wirelessly connected to the server 13. Exemplarily, the wireless connection method between the first device 12 and the blood glucose detection device 11 and the wireless connection method between the first device 12 and the server 13 may both be wireless connections based on wireless fidelity (WIFI), Bluetooth or mobile communication technology, etc.

[0050] Mobile communication technologies may include, for example, the fifth-generation mobile communication technology (5G), the fourth-generation mobile communication technology (4G), the third-generation mobile communication technology (3G), or the second-generation mobile communication technology (2G), etc.

[0051] The blood glucose detection device 11 can be used to determine the blood glucose value of a target object based on the body fluid of the target object, and send the information of the target object, the blood glucose value of the target object, and the determination time of the blood glucose value of the target object to the first device.

[0052] Among them, the information of the target object may include the identity identifier of the target object. The identity identifier of the target object may include, for example, the ID number, name, or phone number of the target object, etc.

[0055] Based on the blood glucose detection system provided in the above embodiments, an embodiment of the present application further provides a blood glucose detection device applied to the blood glucose detection system.

[0056] Please refer to Figure 2 , Figure 2 which is a schematic structural diagram of a blood glucose detection device provided by an embodiment of the present application. As Figure 2 shown, the blood glucose detection device 11 may include a body fluid acquisition unit 111, a body fluid glucose value determination unit 112, and a blood glucose value determination unit 113. Among them, the body fluid acquisition unit 111 is connected to the body fluid glucose value determination unit 112, and the body fluid glucose value determination unit 112 is connected to the blood glucose value determination unit 113.

[0057] Specifically, the body fluid acquisition unit 111 is configured to acquire the body fluid of the target object, generate a first current signal based on the body fluid of the target object, and send the first current signal to the body fluid glucose value determination unit 112.

[0058] Exemplarily, the body fluid may be saliva, tear fluid, urine, tissue fluid, etc.

[0059] It can be understood that the body fluid contains glucose, and the concentration of glucose in the body fluid can be represented by the body fluid glucose value. When the concentration of glucose in the body fluid is different, the current value of the first current signal generated by the body fluid acquisition unit 111 may be different. Specifically, when the concentration of glucose in the body fluid is higher, the current value of the first current signal generated by the body fluid acquisition unit 111 is larger; when the concentration of glucose in the body fluid is lower, the current value of the first current signal generated by the body fluid acquisition unit 111 is smaller.

[0060] The body fluid glucose value determination unit 112 is configured to determine the body fluid glucose value based on the first current signal, and send the body fluid glucose value to the blood glucose value determination unit 113.

[0061] Specifically, the body fluid glucose value determination unit 112 may be configured to determine the body fluid glucose value based on the current value of the first current signal. Exemplarily, a preset correspondence between the current value and the body fluid glucose value may be stored in the blood glucose detection device 11. Based on this, the body fluid glucose value determination unit 112 may be configured to determine the body fluid glucose value corresponding to the first current signal based on the current value of the first current signal and the preset correspondence between the current value and the body fluid glucose value, and send the body fluid glucose value corresponding to the first current signal to the blood glucose value determination unit 113.

[0062] The blood glucose value determination unit 113 is configured to determine the blood glucose value of the target object based on the body fluid glucose value.

[0063] Optionally, a preset correspondence between the body fluid glucose value and the blood glucose value may be stored in the blood glucose detection device 11. Based on this, the blood glucose value determination unit 113 may determine the blood glucose value of the target object based on the body fluid glucose value of the target object and the preset correspondence between the body fluid glucose value and the blood glucose value.

[0064] As can be seen from the above, the blood glucose detection device provided by the embodiment of the present application includes a body fluid acquisition unit, a body fluid glucose value determination unit, and a blood glucose value determination unit; wherein, the body fluid acquisition unit is used to acquire the body fluid of the target object, generate a first current signal based on the body fluid, and send the first current signal to the body fluid glucose value determination unit; the body fluid glucose value determination unit is used to determine the body fluid glucose value based on the first current signal and send the body fluid glucose value to the blood glucose value determination unit; the blood glucose value determination unit is used to determine the blood glucose value of the target object based on the body fluid glucose value. Since the blood glucose detection device provided by the embodiment of the present application can process the body fluid of the target object to obtain the blood glucose value of the target object, there is no need for professionals to use professional equipment for blood glucose detection, and ordinary users can use the blood glucose detection device provided by the embodiment of the present application to detect their own blood glucose, thereby improving the convenience of non-invasive blood glucose detection.

[0065] Please refer to Figure 3 , which is a schematic structural diagram of a blood glucose detection device provided by another embodiment of the present application. As Figure 3 shown, in an optional implementation manner, the body fluid acquisition unit 111 may include a body fluid glucose test strip, wherein the body fluid glucose test strip may include a substrate layer 1111, a siphon layer 1112, a bio-enzyme layer 1113, an electrode layer 1114, and an insulating layer 1115.

[0066] Among them, the substrate layer 1111, the electrode layer 1114, the bio-enzyme layer 1113, and the siphon layer 1112 are arranged in sequence, and the insulating layer 1115 covers the electrode layer 1114.

[0067] Specifically, the substrate layer 1111 is used to acquire the body fluid of the target object.

[0068] Exemplarily, the substrate layer 1111 may be obtained by processing with white polyethylene terephthalate (PET) material.

[0069] In practical applications, the target object may smear the body fluid at the target position in the substrate layer 1111, so that the substrate layer 1111 can acquire the body fluid of the target object. Among them, the target position can be set according to actual needs, and no special limitation is made here.

[0070] The siphon layer 1112 is used to suck a quantified amount of the body fluid of the target object to the bio-enzyme layer 1113.

[0071] Exemplarily, the siphon layer 1112 can suck a quantified amount of the body fluid of the target object to the bio-enzyme layer 1113 through a siphon reaction. In different detections, the volume of the body fluid sucked by the siphon layer 1112 to the bio-enzyme layer 1113 can be the same or different. The specific volume of the body fluid sucked by the siphon layer 1112 to the bio-enzyme layer 1113 can be set according to actual requirements, and no special limitation is imposed here.

[0072] The bio-enzyme layer 1113 is used to provide a bio-enzyme, which is used to react with glucose in the body fluid of the target object to generate a first current signal.

[0073] Exemplarily, the bio-enzyme can be prepared by methods such as glucose oxidase / peroxidase method or hexokinase / 6-phosphoglucose dehydrogenase method. The bio-enzyme can be customized based on the detection range and detection accuracy. No special limitation is imposed on the specific selection of the bio-enzyme type and the specific customization process of the bio-enzyme here.

[0074] The electrode layer 1114 is used to obtain the first current signal generated by the bio-enzyme layer 1113 and send the first current signal to the body fluid glucose value determination unit 112.

[0075] In an optional implementation manner, the electrode layer 1114 can include a reaction area 11141, a transmission area 11142, and a connection area 11143. Among them, the reaction area 11141 can be connected to the transmission area 11142, and the transmission area 11142 can be connected to the connection area 11143. The insulating layer 1115 can be used to cover the transmission area 11142 of the electrode layer 1114 to provide insulation protection for the transmission area 11142.

[0076] Specifically, the reaction area 11141 can be the area where glucose in the body fluid reacts with the bio-enzyme. The reaction area 11141 can obtain the first current signal generated by the reaction of glucose in the body fluid with the bio-enzyme and send the first current signal to the transmission area 11142.

[0077] The transmission area 11142 can send the first current signal obtained by the reaction area 11141 to the connection area 11143.

[0078] The connection area 11143 can be connected to the body fluid glucose value determination unit 112, and the connection area 11143 can be used to send the first current signal to the body fluid glucose value determination unit 112.

[0079] In this implementation manner, the electrode layer 1114 can include N first electrodes. Exemplarily, please refer to Figure 4 , Figure 4The structural schematic diagram of the electrode layer provided by the embodiment of the present application is as follows Figure 4 As shown, each first electrode may include a front portion 41, a middle portion 42, and a rear portion 43.

[0080] Specifically, the front portion 41 of the first electrode may serve as the reaction region 11141 of the electrode layer 1114, the middle portion 42 of the first electrode may serve as the transmission region 11142 of the electrode layer 1114, and the rear portion 43 of the first electrode may serve as the connection region 11143 of the electrode layer 1114.

[0081] Optionally, the first electrode includes n reaction electrodes, m signal electrodes, and k spare electrodes, where n + m + k = N. Exemplarily, as Figure 4 shown, electrode a, electrode b, and electrode e may serve as reaction electrodes, electrode c may serve as a signal electrode, and electrode d may serve as a spare electrode.

[0082] Among them, the n reaction electrodes can be used to obtain the first current signal generated in the reaction region 11141; the m signal electrodes can be used to control the working state of the body fluid glucose value determination unit 112. Specifically, when the first current signal is generated in the reaction region 11141, the m signal electrodes can control the body fluid glucose value determination unit 112 to determine the body fluid glucose value based on the first current signal; the k spare electrodes can replace the reaction electrode or the signal electrode to work when the reaction electrode or the signal electrode malfunctions. It should be noted that the specific values of n, m, and k can be set according to actual needs and are not specifically limited here.

[0083] In this implementation manner, the electrode material of the first electrode may include a silver / silver chloride paste layer, a graphene / carbon paste layer, and a PEDOT:PSS layer. Among them, PEDOT:PSS is an aqueous solution of a polymer, composed of two substances, PEDOT and PSS. Among them, PEDOT is a polymer of EDOT (3,4-ethylenedioxythiophene monomer), and PSS is polystyrene sulfonate. In the first electrode, the ratio and thickness of the silver / silver chloride paste layer, the graphene / carbon paste layer, and the PEDOT:PSS layer can be set according to requirements and are not specifically limited here.

[0084] In another optional implementation manner, the body fluid glucose value determination unit 112 may specifically include a signal amplification unit 1121, a temperature measurement unit 1122, and a first determination unit 1123.

[0085] Among them, the signal amplification unit 1121 can be connected to the electrode layer 1114 and the first determination unit 1123. Specifically, the signal amplification unit 1121 can be connected to the conduction area 11143 in the electrode layer 1114; the temperature measurement unit 1122 can be connected to the first determination unit 1123; the first determination unit 1123 is connected to the blood glucose value determination unit 113.

[0086] The signal amplification unit 1121 is configured to receive the first current signal, perform signal amplification processing on the first current signal, and send the first current signal after signal amplification processing to the first determination unit 1123.

[0087] It can be understood that since the glucose value in the body fluid is usually low, the current value of the first current signal generated by the reaction of glucose and biological enzymes in the body fluid is low. Therefore, after the signal amplification unit 1121 performs signal amplification processing on the first current signal, it is convenient for the first determination unit 1123 to accurately determine the body fluid glucose value of the target object based on the first current signal after signal amplification processing.

[0088] The temperature measurement unit 1122 is configured to obtain the temperature value at the current moment and send the temperature value at the current moment to the first determination unit 1123.

[0089] Among them, the current moment can be any moment when the body fluid glucose value determination unit 112 needs to obtain the temperature value after obtaining the first current signal.

[0090] It can be understood that since temperature will affect the activity of biological enzymes, based on this, temperature will affect the current value of the first current signal generated by the reaction of glucose and biological enzymes in the body fluid, the body fluid glucose value, and the blood glucose value. Therefore, by obtaining and sending the temperature value at the current moment to the first determination unit 1123, the temperature measurement unit 1122 can enable the first determination unit 1123 to more accurately determine the body fluid glucose value.

[0091] The first determination unit 1123 is configured to determine the body fluid glucose value based on the first current signal after signal amplification processing and the temperature value, and send the body fluid glucose value to the blood glucose value determination unit 113.

[0092] In an alternative implementation, since the first current signal after signal amplification processing is an analog signal, the first determination unit 1123 can specifically be configured to perform analog-to-digital conversion on the first current signal after signal amplification processing to obtain the current value of the first current signal, and determine the body fluid glucose value based on the current value of the first current signal and the temperature value at the current moment. Specifically, the first determination unit 1123 can determine the body fluid glucose value based on the current value of the first current signal, the temperature value at the current moment, and a second preset function. The second preset function can be used to describe the preset corresponding relationship among the current value, the temperature value, and the body fluid glucose value.

[0093] In another alternative implementation, the first determination unit 1123 can specifically be configured to perform analog-to-digital conversion on the first current signal after signal amplification processing to obtain the current value of the first current signal, and determine the body fluid glucose value based on the current value of the first current signal. In this implementation, the first determination unit 1123 can determine the body fluid glucose value based on the current value of the first current signal and the second preset function. Based on this, the second preset function can be used to describe the preset corresponding relationship between the current value and the body fluid glucose value.

[0094] Exemplarily, in the above implementations, the second preset function can be obtained by pre-measurement through multiple experiments.

[0095] The blood glucose value determination unit 113 is configured to determine the blood glucose value based on the body fluid glucose value and a first preset function.

[0096] The first preset function can be used to describe the preset corresponding relationship between the body fluid glucose value and the blood glucose value. In specific applications, the first preset function can be obtained by pre-measurement through multiple experiments.

[0097] In an alternative implementation, the blood glucose detection device 11 can further include a communication unit 114 connected to the blood glucose value determination unit 113. Based on this, the blood glucose detection device 11 can establish a wireless connection with the first device 12 through the communication unit 114.

[0098] Exemplarily, the communication unit 114 can be a WIFI unit, a Bluetooth unit, a mobile communication unit, or the like.

[0099] Based on this, the blood glucose value determination unit 113 is further configured to send the blood glucose value of the target object to the communication unit 114 after determining the blood glucose value of the target object.

[0100] The communication unit 114 can be configured to send the blood glucose value of the target object to the first device 12 after receiving the blood glucose value of the target object sent by the blood glucose value determination unit 113.

[0101] In an alternative implementation, the blood glucose detection device 11 may further include a storage unit 115 connected to the blood glucose value determination unit 113.

[0102] The blood glucose value determination unit 113 is further configured to obtain information of the target object and the determination time of the blood glucose value of the target object, and send the information of the target object, the blood glucose value of the target object, and the determination time of the blood glucose value of the target object to the storage unit 115.

[0103] The information of the target object may be input by the target object into the blood glucose value determination unit 113, and the determination time of the blood glucose value of the target object may be the time when the blood glucose value determination unit 113 determines the blood glucose value of the target object.

[0104] The storage unit 115 may be configured to, after receiving the information of the target object, the blood glucose value of the target object, and the determination time of the blood glucose value of the target object, store the information of the target object, the blood glucose value of the target object, and the determination time of the blood glucose value of the target object in an associated manner.

[0105] In addition, the storage unit 115 may further store a preset correspondence relationship between the current value, the temperature value, and the body fluid glucose value, and a preset correspondence relationship between the body fluid glucose value and the blood glucose value.

[0106] In practical applications, the storage unit 115 may be any combination of one or more of a read-only memory (ROM), a random access memory (RAM), a flash memory, a USB flash drive, and an SD memory card. The embodiments of the present application do not particularly limit the type of the storage unit 115.

[0107] In an alternative implementation, the blood glucose detection device 11 may further include a voice broadcast unit 116 connected to the blood glucose value determination unit 113.

[0113] The following combines Figure 3 , and details the specific working principle of the blood glucose detection device provided in the embodiments of the present application.

[0114] When the target object needs to detect its own blood glucose, the body fluid can be applied to the corresponding position of the substrate layer 1111 in the body fluid glucose test strip in the body fluid acquisition unit 111. The siphon layer 1112 can quantitatively suck the body fluid applied to the corresponding position in the substrate layer 1111 to the bio-enzyme layer 1113. Glucose in the body fluid and the bio-enzyme in the bio-enzyme layer 1113 will react in the reaction area 11141 in the electrode layer 1114 to generate a first current signal. The reaction area 11141 can acquire the first current signal generated by the reaction of glucose in the body fluid and the bio-enzyme, and send the first current signal to the transmission area 11142.

The temperature measurement unit 1122 in the body fluid glucose value determination unit 112 can acquire the temperature value at the current moment, and send the temperature value at the current moment to the first determination unit 1123. The first determination unit 1123 in the body fluid glucose value determination unit 112 can, after receiving the first current signal after signal amplification processing, determine the body fluid glucose value based on the first current signal after signal amplification processing, the temperature value at the current moment, and the second preset function, and send the body fluid glucose value to the blood glucose value determination unit 113.

[0116] After receiving the body fluid glucose value sent by the body fluid glucose value determination unit 112, the blood glucose value determination unit 113 can determine the blood glucose value based on the body fluid glucose value and the first preset function. In addition, the blood glucose value determination unit 113 can also obtain the information of the target object and the determination time of the blood glucose value.

[0117] The blood glucose value determination unit 113 can also send the blood glucose value, the information of the target object, and the determination time of the blood glucose value to the storage unit 115. After receiving the blood glucose value, the information of the target object, and the determination time of the blood glucose value sent by the blood glucose value determination unit 113, the storage unit 115 can store the blood glucose value, the information of the target object, and the determination time of the blood glucose value in an associated manner.

[0118] The blood glucose value determination unit 113 can also send the blood glucose value to the voice broadcast unit 116. After receiving the blood glucose value sent by the blood glucose value determination unit 113, the voice broadcast unit 116 can perform a voice broadcast on the blood glucose value.

[0119] The blood glucose value determination unit 113 can also send the blood glucose value to the display unit 117. After receiving the blood glucose value sent by the blood glucose value determination unit 113, the display unit 117 can display the blood glucose value.

[0120] The blood glucose value determination unit 113 can also send the blood glucose value, the information of the target object, and the determination time of the blood glucose value to the communication unit 114. After receiving the blood glucose value, the information of the target object, and the determination time of the blood glucose value sent by the blood glucose value determination unit 113, the communication unit 114 can send the blood glucose value, the information of the target object, and the determination time of the blood glucose value to the first device 12 through wireless communication.

[0121] After receiving the blood glucose value, the information of the target object, and the determination time of the blood glucose value sent by the blood glucose detection device 11, the first device 12 can automatically send the blood glucose value, the information of the target object associated with the blood glucose value, and the determination time of the blood glucose value associated with the blood glucose value to the server 13 through wireless communication.

[0122] After receiving the blood glucose value, the information of the target object, and the determination time of the blood glucose value sent by the first device 12, the server 13 can store the blood glucose value, the information of the target object associated with the blood glucose value, and the determination time of the blood glucose value associated with the blood glucose value in an associated manner in a preset database.

[0123] The first device 12 can also send the information of the target object or the determination time of the blood glucose value to the server 13. After receiving the information of the target object or the determination time of the blood glucose value, the server 13 can obtain the information of the target object or the blood glucose value corresponding to the determination time of the blood glucose value based on the information of the target object or the determination time of the blood glucose value, and send the blood glucose value to the first device 12.
