[0027] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the embodiments of the present application should fall within the scope of protection of the embodiments of the present application.
[0028] The technical solution provided in the embodiment of the present application relates to analyte monitoring. Analyte refers to a specific component or substance that needs to be measured in a sample, and the present application does not limit the analyte. For the convenience of explanation, the analyte is glucose, and the analyte monitoring is used to obtain the monitoring data of the analyte, and the monitoring data of the analyte is blood glucose data as an example for explanation. Wherein, blood glucose is also called blood glucose, which refers to the content of glucose in the blood, and the units of blood glucose data include millimoles per liter (mmol / l) and milligrams per deciliter (mg / dl).
[0029] For example, Figure 1 FIG. 1 is a schematic diagram of an analyte monitoring system applicable to an embodiment of the present application. Figure 1As shown, the analyte monitoring system includes an analyte monitoring device 100 and an electronic device 200, and the analyte monitoring device 100 includes an analyte monitoring sensor 11. The analyte monitoring sensor 11 is used to react chemically with the analyte to generate an electric current. The analyte monitoring device 100 measures the generated current to obtain measurement data, and the measurement data characterizes the magnitude of the generated current. Subsequently, the analyte monitoring device 100 or the electronic device 200 processes the measurement data to obtain the monitoring data of the analyte. The analyte monitoring device 100 can establish a communication connection with the electronic device 200 to transmit data related to the analyte, for example, measurement data, monitoring data of the analyte, or calibration data and anti-tampering data mentioned later in this application. An application (Application, APP) is pre-installed on the electronic device 200 to implement the relevant functions of analyte monitoring. The user can obtain data related to the analyte by operating the APP to realize the monitoring of the analyte. For example, the user can view blood glucose data in real time. This application does not limit the name of the APP, the layout of the display interface, etc.
[0030] It should be noted that the present application does not limit the name and type of electronic devices. For example, electronic devices are also called terminal devices, and electronic devices are, for example, mobile phones, tablet computers, wearable devices, etc.
[0031] In order to facilitate the understanding of the present application, an implementation of the analyte monitoring device is first described.
[0032] For example, Figure 2 As shown, the analyte monitoring device 100 includes: an analyte monitoring sensor 11, a connector 12, a transmitter 16, a microcontroller unit (MCU), a Bluetooth Low Energy (BLE) module and a power module 13.
[0033] The analyte monitoring sensor 11 and the transmitter 16 are connected via a connector 12 .
[0034] The analyte monitoring sensor 11 includes a substrate on which a detection electrode 111 and a pad 112 are disposed. The detection electrode 111 is used to chemically react with the analyte and generate a current under the action of an excitation signal provided by the transmitter 16. The pad 112 is an electrical connection point on the analyte monitoring sensor 11, and the connector 12 is electrically connected to the pad 112.
[0035] The transmitter 16 is used to apply an excitation signal to the detection electrode 111 on the analyte monitoring sensor 11 through the connector 12, and obtain the current generated by the detection electrode 111 through the connector 12, and convert the current into measurement data.
[0036] MCU is used to process the measurement data to obtain the monitoring data of the analyte.
[0037] BLE module for communicating with electronic devices.
[0038] Specifically, the analyte monitoring device 100 is a continuous glucose monitoring (CGM) device, and the analyte monitoring sensor 11 is a glucose biosensor (sensor) as an example. Figure 2 , the CGM device includes a glucose biosensor and a transmitter. The glucose biosensor and the transmitter are connected by a connector, such as a metal shrapnel contact connector or a conductive rubber connector. The glucose biosensor requires the transmitter to apply a stable voltage to it in order to work properly. Under the action of voltage, the glucose biosensor reacts with the glucose in the blood to generate a current signal. The generated current signal is converted into measurement data after measurement by the transmitter. The measurement data characterizes the magnitude of the current. Subsequently, the blood glucose data is obtained by further processing the measurement data to achieve blood glucose monitoring.
[0039] When people use CGM devices, they wear the CGM devices on the surface of the skin, such as on their arms. CGM devices currently include two ways of use. One way is that the glucose biosensor and the transmitter are implanted in the skin as an integrated whole. After the use cycle of the glucose biosensor ends, the glucose biosensor and the transmitter are completely discarded. The other way of use is the split type, specifically: the glucose biosensor is implanted in the skin, and then the transmitter is connected to the glucose biosensor. After the use cycle of the glucose biosensor ends, the transmitter can be removed and retained, and the glucose biosensor is discarded, while the transmitter can be reused many times.
[0040] For the above two usage methods, the glucose biosensor and transmitter in the CGM device need to be connected through a connector. In order to ensure the monitoring accuracy and service life of the CGM device, the connector needs to be waterproofed and form a corresponding waterproof area. The CGM device is usually small in size, so high requirements are placed on the structure of the connector and the reliability of the connection between the connector and the glucose biosensor and the transmitter. The connection between the glucose biosensor and the transmitter through a connector is relatively complicated. If there is a problem with the structure of the connector itself, or if there is a problem with the assembly and connection operation of the connector, it will directly affect the current excitation of the glucose biosensor and the accuracy and stability of the current measurement, thereby affecting the accuracy and stability of the glucose data monitored by the CGM device.
[0041] In addition, in order to ensure the accuracy of the monitoring data of the analyte obtained during the analyte monitoring process, the monitoring data of the analyte needs to be calibrated. Taking the CGM device as an example, data calibration is required when the user uses the CGM device for the first time; or, data calibration is performed periodically during use, for example, usually once every 3 to 6 months. Specifically, in the process of monitoring blood glucose data, the glucose biosensor reacts chemically with the glucose in the blood to generate current, and the generated current is measured to obtain measurement data, which characterizes the magnitude of the current. Further, the measurement data is processed to obtain blood glucose data. The magnitude of the current and the blood glucose data can be simply understood as having a conversion relationship, for example, how many nanoamperes (nA) of current corresponds to how many mmol / l of blood glucose. The so-called data calibration of the monitoring data of the analyte is to determine the conversion relationship between the magnitude of the current and the blood glucose data. It should be noted that the conversion relationship between the magnitude of the current and the blood glucose data is only an exemplary description. In the actual data processing process, how to process and calculate the measurement data to obtain the monitoring data of the analyte, this embodiment does not limit the processing process.
[0042] Data calibration can be completed by the CGM device or by an electronic device that communicates with the CGM device. Specifically, during the production process of the CGM device, a test system is used to test the glucose biosensor in the CGM device and save the calibration data. The calibration data includes current data obtained by measuring the current generated by the glucose biosensor. Subsequently, when the CGM device or electronic device performs data calibration, it is necessary to obtain the calibration data and complete the data calibration based on the calibration data.
[0043] Combine the following Figure 3 and Figure 4 , taking the scenario of a user using a CGM device for the first time as an example, the data calibration process is illustrated.
[0044] Figure 3 The flowchart of a data calibration method shows the process of obtaining calibration data through a test system. The execution subject is a terminal device with data processing capability and connected to the test system. The test system is a pre-built one that can provide a chemical reaction environment for the glucose biosensor and obtain the generated current data. Figure 3 As shown, the data calibration method comprises:
[0045] S301. Encode a plurality of glucose biosensors.
[0046] In this step, the glucose biosensors are encoded, that is, identification information corresponding to the plurality of glucose biosensors is determined.
[0047] The identification information of the glucose biosensor can uniquely distinguish different glucose biosensors. This embodiment does not limit the implementation of the identification information, such as a QR code, a bar code, or a serial number.
[0048] Optionally, the identification information of the glucose biosensor may be stored on a medium corresponding to the glucose biosensor, for example, by printing the identification information on a sterile package of the glucose biosensor or CGM device.
[0049] S302 , after the glucose biosensor to be tested is placed in the test system, the test system is connected to perform coding identification on the glucose biosensor to be tested.
[0050] In this step, the code of the glucose biosensor to be tested is identified, that is, the identification information of the glucose biosensor to be tested is obtained.
[0051] S303: Acquire calibration data obtained by the test system through testing the glucose biosensor to be tested.
[0052] S304: Determine whether the calibration data of the glucose biosensor to be tested is qualified.
[0053] This application does not limit the conditions for whether the calibration data is qualified.
[0054] If the calibration data is qualified, execute S305;
[0055] Otherwise, if the calibration data is unqualified, execute S306.
[0056] S305. Upload the calibration data of the glucose biosensor to be tested to the server.
[0057] S306: Determine that the glucose biosensor to be tested is a defective product.
[0058] Figure 4 This is a flow chart of another data calibration method, which shows the process of data calibration of an electronic device. For example, the electronic device is a mobile phone, and when the CGM device is used for the first time, the CGM device establishes a communication connection with the mobile phone, and the electronic device completes the data calibration.
[0059] like Figure 4 As shown, the data calibration method comprises:
[0060] S401. Obtain identification information of an analyte monitoring sensor in a CGM device.
[0061] S402: Send a calibration data acquisition request to a server, where the calibration data acquisition request includes identification information of the analyte monitoring sensor.
[0062] S403. Receive calibration data of the analyte monitoring sensor sent by the server.
[0063] S404 , performing data calibration of the analyte monitoring data according to the calibration data of the analyte monitoring sensor.
[0064] Combination Figure 2 In the structure shown, in the analyte monitoring device, the analyte monitoring sensor 11 is connected to the transmitter 16 via a connector 12. In the pre-built test system, usually only the analyte monitoring sensor is tested, and the part of measuring the current generated by the analyte monitoring sensor is completed by the test system, thereby generating verification data. However, during the use of the analyte monitoring device, the transmitter measures the current generated by the analyte monitoring sensor and converts it into measurement data. Therefore, the accuracy of the data processed by the analyte monitoring device is not only related to the analyte monitoring sensor, but also to the transmitter. At present, the accuracy of the calibration data obtained by the test system is low. Furthermore, the calibration data needs to be stored in advance on the server. When the analyte monitoring device or electronic equipment needs to perform data calibration, the calibration data needs to be obtained from the server. The data transmission process is relatively cumbersome, which affects the efficiency of data calibration.
[0065] The embodiment of the present application provides an analyte monitoring sensor, in which both the detection electrode and the measurement module are arranged inside the analyte monitoring sensor, thereby avoiding the complex and unreliable connection between the detection electrode and the measurement module, and electrically connecting the detection electrode and the measurement module through metal wiring, thereby improving the connection reliability, thereby improving the accuracy and reliability of current detection and measurement, and improving the accuracy and stability of the information data of the analyte monitoring sensor. Moreover, the measurement module can also store calibration data for calibrating the monitoring data of the analyte, simplifying the data calibration process of the analyte monitoring sensor, and improving the efficiency and accuracy of data calibration.
[0066] The present application also provides an analyte monitoring device, including an analyte monitoring sensor. Optionally, the analyte monitoring device may also include a first processor for implementing functions such as data calibration and determining analyte monitoring data. Depending on whether the analyte monitoring device includes the first processor, the present application is applicable to Figure 5A to Figure 5C Analyte monitoring system shown.
[0067] In one implementation, Figure 5AAs shown, the analyte monitoring system includes an analyte monitoring device 100 and an electronic device 200. The analyte monitoring device 100 includes an analyte monitoring sensor 11, a communication module 14, a power module 13, and a first processor 15. The electronic device 200 includes a second processor 21. In this implementation, the analyte monitoring device 100 includes a first processor 15, and the analyte monitoring device 100 can implement functions such as data calibration and determining monitoring data of the analyte based on measurement data through the first processor 15, or the electronic device 200 can implement functions such as data calibration and determining monitoring data of the analyte based on measurement data through the second processor 21.
[0068] In another implementation, Figure 5B As shown, the analyte monitoring system includes an analyte monitoring device 100 and an electronic device 200. The analyte monitoring device 100 includes an analyte monitoring sensor 11, a communication module 14 and a power module 13, wherein the communication module 14 includes a first processor 15. The electronic device 200 includes a second processor 21. Figure 5B and Figure 5A The difference is that in Figure 5B In the embodiment, the first processor 15 included in the analyte monitoring device 100 is a processor in the communication module 14. For example, the communication module 14 is a BLE chip, which includes the first processor. In this implementation, the analyte monitoring device 100 can implement functions such as data calibration and determining the monitoring data of the analyte according to the measurement data through the first processor 15, or the electronic device 200 can implement functions such as data calibration and determining the monitoring data of the analyte according to the measurement data through the second processor 21.
[0069] In yet another implementation, Figure 5C As shown, the analyte monitoring system includes an analyte monitoring device 100 and an electronic device 200. The analyte monitoring device 100 includes an analyte monitoring sensor 11, a communication module 14, and a power module 13. The electronic device 200 includes a second processor 21. In this implementation, the electronic device 200 implements functions such as data calibration and determining the monitoring data of the analyte based on the measurement data through the second processor 21.
[0070] The specific implementation of the embodiment of the present application is further explained below in conjunction with the accompanying drawings of the embodiment of the present application.
[0071] Figure 6 A schematic diagram of the structure of the analyte monitoring sensor provided in the embodiment of the present application. Figure 6 As shown, the analyte monitoring sensor 11 provided in this embodiment includes:
[0072] The detection electrode 111 and the measurement module 114 are connected via metal wiring.
[0073] The detection electrode 111 is used to chemically react with the analyte under the action of an excitation signal to generate an electric current.
[0074] The measuring module 114 is used to apply an excitation signal to the detection electrode 111 and convert the current generated by the detection electrode 111 into measurement data.
[0075] The analyte monitoring sensor provided in this embodiment includes a detection electrode 111 and a measurement module 114 in structure, which are connected by metal wiring. Since the detection electrode 111 and the measurement module 114 are both arranged inside the analyte monitoring sensor, Figure 2 Compared with the structure of the analyte monitoring device shown in the figure, the connection method between the detection electrode and the measurement module is simplified and the connection reliability is improved.
[0076] The analyte monitoring sensor provided in this embodiment has the following working principle: the measuring module 114 applies an excitation signal to the detection electrode 111. Signal excitation refers to a method of driving a circuit or component to work by applying an excitation signal, and signal excitation includes voltage excitation and current excitation. In this embodiment, the excitation signal refers to an electrical signal applied in order to allow the detection electrode to react chemically with the analyte, and the excitation signal may be an excitation voltage signal. Under the action of the excitation signal, the detection electrode 111 reacts chemically with the analyte to generate current. The current generated by the detection electrode 111 is transmitted to the measuring module 114 through metal wiring. The measuring module 114 converts the current into measurement data, and the measurement data characterizes the magnitude of the current. Subsequently, the analyte monitoring device or electronic device can obtain the monitoring data of the analyte based on the measurement data.
[0077] It can be seen that in this embodiment, by setting both the detection electrode and the measurement module in the analyte monitoring sensor, the connection method between the detection electrode and the measurement module is simplified, the connection reliability is improved, and the accuracy and reliability of current detection and measurement are improved. It is not affected by other functional circuits and electronic devices, and the accuracy and stability of the information data of the analyte monitoring sensor are improved.
[0078] Optionally, in one implementation, the measurement module 114 is a chip. The chip is formed by integrating and packaging the analog circuits required for the current signal excitation and measurement of the analyte monitoring sensor through IC chip (Integrated Circuit Chip) design and production technology, and the chip has pins for electrical connection with other components. This embodiment does not limit the type, size and structure of the chip. The measurement module uses a packaged chip and is electrically connected to the detection electrode through metal wiring, and the implementation method is simple.
[0079] Furthermore, the chip is an analog front end (AFE) chip. The main function of the AFE chip is to convert the analog signal from the sensor into a digital signal for subsequent data analysis and processing by a microprocessor or a data processing system. In this embodiment, the AFE chip obtains the current generated by the chemical reaction between the detection electrode and the analyte, which is an analog signal. By converting the analog signal into a digital signal, measurement data can be obtained to characterize the magnitude of the current. The AFE chip can eliminate high-order harmonics, improve the power factor, and has excellent dynamic characteristics. The measurement module uses a packaged AFE chip, which is simple to implement, energy-saving, and has stable processing capabilities.
[0080] Optionally, in another implementation, the measurement module 114 is a measurement circuit constructed by discrete components. In this implementation, the measurement module can be an unpackaged circuit with a flexible and diverse circuit structure, and the implementation is more flexible.
[0081] Combine the following Figure 7 , a structure of an analyte monitoring sensor is described.
[0082] like Figure 7 As shown, the analyte monitoring sensor 11 includes a substrate 113 , on which a detection electrode 111 , a measurement module (specifically an AFE chip 114 ) and a metal trace 115 are disposed.
[0083] Specifically, the substrate 113 may be a flexible substrate. The material of the substrate 113 may be polycarbonate (PC), polyethylene terephthalate (PET) or polyimide (PI), etc., which is not limited in this embodiment. The thickness of the substrate 113 may be between 0.01 mm and 0.2 mm. The detection electrode 111 is prepared on the substrate 113 by screen printing, inkjet printing, micro electromechanical system (MEMS) and other technologies. The detection electrode 111 may be a three-electrode system, for example, Figure 7As shown, the detection electrode 111 includes a working electrode 116, a counter electrode 118 and a reference electrode 117. The working electrode can be represented as WE, the reference electrode can be represented as RE, and the counter electrode can be represented as CE. The working electrode is used for electrochemical reactions, the reference electrode is used to provide a constant potential to ensure the accuracy of the measurement, and the counter electrode assists the current flow. The three-electrode system can simultaneously control and measure current and potential to avoid polarization errors. Optionally, the detection electrode 111 can also be a dual-channel four-electrode system, including two working electrodes, a counter electrode and a reference electrode. This embodiment does not limit the material and size of the working electrode 116, the counter electrode 118 and the reference electrode 117. For example, the materials of the working electrode 116 and the counter electrode 118 may include carbon, gold, platinum, etc., and the material of the reference electrode 117 may include silver, silver silver, silver chloride, etc.
[0084] exist Figure 7 In the embodiment, the measuring module 114 is an AFE chip. The AFE chip can be constructed in situ on the substrate 113 by using a chip process, or an AFE chip that meets the conditions can be welded on the substrate 113.
[0085] like Figure 7 As shown, the measurement module 114 further includes a pin 120 for electrically connecting to other components, thereby achieving electrical connection between the analyte monitoring sensor and other components.
[0086] like Figure 7 As shown, a functional membrane layer is also constructed on the periphery of the detection electrode 111 on the analyte monitoring sensor 11, which is used to realize the chemical reaction between the detection electrode 111 and the analyte. It can be understood that the composition of the functional membrane layer is different for different analytes. For example, when the analyte is glucose, the functional membrane layer is a biological membrane layer for chemically reacting with glucose.
[0087] The analyte monitoring sensor provided in this embodiment is applied to an analyte monitoring device. In one implementation, the measurement module is also used to store calibration data. The calibration data is used to perform data calibration on the monitoring data of the analyte. The monitoring data of the analyte is obtained by processing the measurement data by the analyte monitoring device or the electronic device.
[0088] The calibration data generation process can be found in Figure 3 The principle is similar to that described in the previous embodiment and will not be described in detail here. Figure 3 There is a difference in the content of the calibration data.
[0089] exist Figure 3In the test, since the analyte monitoring sensor and the transmitter are separate structures, the analyte monitoring sensor includes the detection electrode but not the transmitter. Therefore, the test system tests the part of the analyte monitoring sensor that generates current by chemical reaction of the detection electrode, while the part that converts the current into calibration data is provided by the test system. It can be understood that Figure 3 The calibration data in the calibration data is for the detection electrode in the analyte monitoring sensor. Subsequently, during the use of the analyte monitoring device, the detection electrode in the analyte monitoring sensor remains unchanged, but the emitter has changed. Therefore, the accuracy of the calibration data is affected, resulting in low accuracy of the calibration data.
[0090] In this embodiment, since the analyte monitoring sensor includes a detection electrode and a measurement module, the test system can test the detection electrode and the test module in the analyte monitoring sensor together, that is, the calibration data in this embodiment is for the detection electrode and the measurement module in the analyte monitoring sensor. Subsequently, during the use of the analyte monitoring device, the detection electrode and the measurement module in the analyte monitoring sensor remain unchanged, and the analyte monitoring data is calibrated based on the calibration data, thereby improving the accuracy of data calibration.
[0091] Furthermore, since the analyte monitoring sensor includes a measurement module, the measurement module stores calibration data, so that the calibration data can be obtained from the measurement module when the subsequent analyte monitoring device or electronic device performs data calibration. Figure 4 Compared with the data calibration process shown in FIG. 1 , in this embodiment, the analyte monitoring device or electronic device does not need to establish a connection with the server to obtain calibration data, which simplifies the data calibration process and improves the data calibration efficiency.

[0117] Optionally, in another implementation, such as Figure 5B As shown, the first processor is located in the communication module. In this implementation, the monitoring data of the analyte is determined by the first processor in the communication module to implement the data calibration process. In the scenario of real-time monitoring of the analyte, the amount of data is small, and the data is processed by the first processor of the communication module, which reduces the number of components in the analyte monitoring device, simplifies the structure and size of the analyte monitoring device, and reduces the cost.

The electronic device can obtain calibration data from the measurement module in the analyte monitoring device, and does not need to connect to the server to obtain the calibration data, which simplifies the data transmission method and improves the efficiency of data calibration. Moreover, the calibration data is targeted at the detection electrode and the measurement module in the analyte monitoring sensor, and the calibration data is more accurate, which improves the accuracy of data calibration.
