Description
Technical Field

Chronic diseases such as diabetes have become public health problems worldwide. Diabetes is a metabolic disorder syndrome of sugar, fat, protein, water, electrolyte and the like caused by hypofunction of human pancreatic islets, insulin resistance and the like due to various pathogenic reasons such as immune dysfunction, genetic factors and the like. At present, no radical treatment method for diabetes exists, and the diabetes patient often controls the disease condition by monitoring blood sugar.

Compared with the traditional blood sugar monitoring, the CGM technology can monitor the blood sugar of a patient for at least 24 hours continuously, obtain the blood sugar condition of the patient all day in real time, and effectively reflect the hypoglycemia and blood sugar fluctuation condition of the patient. A dynamic blood glucose monitoring system generally includes a sensor probe and a processing device that records sensed information. In dynamic blood glucose monitoring, a sensor probe is usually buried under the skin of a subject, and generates an electrical signal through a chemical reaction with glucose in interstitial fluid of the skin tissue, and a processing device processes the electrical signal to obtain a blood glucose value and a blood glucose change condition of a patient.
In order to obtain a more accurate blood glucose value, the sensor probe of the dynamic blood glucose monitoring system is often tested at the time of shipment. In the existing test, the electrical signals in the corresponding sensor probes are often identified by acquiring the physical addresses embedded in the dynamic blood glucose monitoring system, but the test efficiency of the test method is low, and a lot of improvement spaces exist.

(platform for testing electrochemical parameters)
Fig. 1 is a schematic structural diagram of a platform for testing electrochemical parameters according to the present disclosure. Fig. 2 is a schematic top view of a platform for testing electrochemical parameters in accordance with the present disclosure. The electrochemical parameter testing platform 1 of the present disclosure may be suitable for batch testing of consistency of electrochemical parameters of a plurality of samples 10 to be tested. In the present disclosure, the test platform 1 for electrochemical parameters may be referred to simply as test platform 1.
In some examples, as shown in fig. 1, the testing platform 1 may include a plurality of samples to be tested 10, a carrier device 20, and a determination device 30. The number of the samples 10 to be measured may be n, where n represents the number of the samples 10 to be measured, and n is a natural number. As shown in fig. 2, the n samples 10 to be measured may be arranged in a row, and the example of the present disclosure is not limited thereto, and the n samples 10 to be measured may also be arranged in a matrix or other shapes. The carrier 20 may contain a reaction solution with which the sensing parts 11 (described later) of the plurality of samples 10 to be measured are brought into contact and electrochemically reacted. The sample to be measured 10 may transmit the electrochemical parameters of the generated reaction solution to the determination device 30 through the communication bus.
(sample to be tested)
In some examples, as shown in fig. 1 or fig. 2, the number of samples 10 to be tested may be n, which is a natural number. For example, the number n of samples 10 to be tested may be, for example, 10, 20, 50, 100, 200. In addition, the number of samples 10 to be measured may also be 200 or more, but examples of the present disclosure are not limited thereto.
Fig. 3 is a block diagram of a test sample according to the present disclosure. Fig. 4 is a schematic view of a sample to be tested according to the present disclosure. Fig. 5 is a schematic view of a sample to be tested and a carrying device according to the present disclosure.
In some examples, as shown in fig. 3, the sample 10 to be tested may include a sensing portion 11. For example, the sensing part 11 shown in fig. 4 may be located at the bottom of the sample 10 to be measured. During the test, as shown in fig. 5, the sensing part 11 of the sample 10 to be tested may contact with a reaction solution in the carrier 20 (described later) to perform an electrochemical reaction, and detect an electrochemical parameter of the reaction solution. In other words, the sample 10 to be tested may be provided with the sensor portion 11 for detecting the electrochemical parameters of the reaction solution during the test.
In some examples, the sensing portion 11 may be a working electrode (not shown) of the sample 10 to be measured. The working electrode may include a sensing layer capable of reacting with the reaction solution. For example, when the reaction solution is a glucose solution, the sensing layer of the working electrode may be a glucolase sensing layer. The glucolase sensing layer of the sensing portion 11 can electrochemically react with the glucose solution and detect the concentration of the glucose solution.
Examples of the disclosure are not limited thereto. The sensing layer of the sensing part 11 can be replaced with replacement of the reaction solution. For example, when the reaction solution is a drug solution, the sensing layer of the sensing part 11 may be replaced with a corresponding reactant so that the sensing part 11 obtains a concentration of a certain drug in the drug solution. For example, antibiotics (e.g., gentamicin, vancomycin, and the like), digitoxin, digoxin, theophylline, and warfarin (warfarin), and the like.
In some examples, the sensing layer may react with the reaction solution to generate a current signal. The sensing portion 11 can acquire and transmit the current signal.
In some examples, the sample 10 to be tested may also include an electronic system (not shown). The sensing part 11 may transmit the current signal to an electronic system, and the electronic system processes the current signal to obtain an electrochemical parameter of the reaction solution, such as glucose concentration.
In some examples, as shown in fig. 3, the sample 10 to be tested may include a memory 12. The memory 12 may store electrochemical parameters of the reaction solution processed by the electronic system. The electrochemical parameters are obtained by processing current signals generated by the reaction of the sensing part 11 and the reaction solution through an electronic system. In other words, the memory 12 may be used for recording the electrochemical parameters read by the sensing portion 11.
In some examples, Memory 12 may be a high-speed RAM Memory, a non-volatile Memory (non-volatile Memory) or a Read-Only Memory (ROM).
In some examples, the sample 10 to be tested may have a specified number of bits of physical address (MAC address). The MAC address may be referred to as a physical address or a hardware address. The MAC address may be used to define the location of the sample 10 to be tested. In other words, the sample 10 to be tested can be identified by the MAC address. The MAC address is 48 bits in length. That is, the prescribed number of bits of the MAC address may be, for example, 48 bits. Typically, one sample 10 to be tested has a globally unique MAC address, and the MAC address is fixed. It can be seen that the respective sample 10 to be tested can be identified by the MAC address.
In some examples, as shown in fig. 3, the sample 10 to be tested may include a clock portion 13. The clock section 13 may be used for timing. The clock sections 13 of the respective samples 10 to be measured are synchronized with each other. Therefore, the electrochemical parameters of the samples 10 to be tested can be synchronously acquired. The synchronization method of the clock section 13 will be described later in detail.
In some examples, the electrochemical parameters read by the sample 10 to be tested and the corresponding reading time of the clock part 13 may also be stored in the memory 12. That is, the memory 12 may also record the read time when the electrochemical parameter is read. In this case, the sample 10 to be tested can obtain the corresponding reading moment when the electrochemical parameters are read.
Fig. 6 is a block diagram of a carrier device according to the present disclosure. In some examples, the test platform 1 may include a carrier 20. As shown in fig. 6, the carrier 20 may include a receiving portion 21 that receives the reaction solution. The number of the accommodating portions 21 may be plural. The different containers 21 may contain the same kind of reaction solution at the same concentration, or may contain the same kind of reaction solution at different concentrations. Examples of the present disclosure are not limited thereto, and different containers 21 may contain different kinds of reaction solutions, for example, the reaction solutions may include, but are not limited to, a glucose solution or the above-described drug solution. Examples of the disclosure are not limited thereto. In addition, the external environment in which the reaction solution in the housing portion 21 is exposed is kept constant.
In some examples, as shown in fig. 6, the carrier 20 may include a stand 22. The holder 22 may be used to place a plurality of samples 10 to be measured so that the sensing part 11 of the samples 10 to be measured is in contact with the reaction solution of the receiving part 21. The reaction solutions in contact with the sensor portions 11 of the respective samples 10 are the same reaction solution having the same concentration.
In some examples, the test platform 1 may comprise the determination device 30. The determination device 30 may be connected to a plurality of samples 10 to be measured. And the judging means 30 may assign an equipment number having a number of bits smaller than the prescribed number of bits of the physical address to each sample 10 to be tested, based on the physical address (MAC address) of the sample 10 to be tested.
In some examples, the determination device 30 may be connected to a plurality of samples 10 to be measured through a communication bus (communication interface) having the same number as that of the equipment to realize data transmission. Specifically, the plurality of samples to be measured 10 may respectively transmit the communication request signal and the corresponding MAC address to the determination device 30, and the determination device 30 may set the address signal and the device number having the number of bits smaller than the prescribed number of bits of the physical address based on the communication request signal and the corresponding MAC address feedback. Each sample 10 may receive a corresponding device number and store the device number in the memory 12 of the corresponding sample 10 for subsequent communication with the determination device 30. The number of bits of the device number may be the same as the number of bits of the communication bus (communication interface), and for example, when the communication bus (communication interface) is 8 bits, the number of bits of the device number is also 8 bits. In this case, identifying the corresponding sample to be tested 10 by the device number and obtaining the electrochemical parameter of the sample to be tested 10 is more efficient than identifying the corresponding sample to be tested 10 by the MAC address and obtaining the electrochemical parameter of the sample to be tested 10.
In some examples, the sample under test 10 may send a transmission data packet containing the device number and the electrochemical parameters to the determination device 30 during the testing process. That is, during the test, the sample 10 to be tested may form a transmission data packet by using the received device number and the corresponding electrochemical parameter in the memory 12, and send the transmission data packet to the determining device 30.
In some examples, the determination device 30 may determine the consistency of the electrochemical parameters obtained from each of the samples 10 to be tested based on the transmission data packet. Specifically, the determination device 30 may receive the transmission data packet and obtain the device number and the electrochemical parameter in the transmission data. The determining device 30 can analyze the electrochemical parameters of the samples 10 to be tested corresponding to different equipment numbers at the same time to determine the consistency of the electrochemical parameters obtained by each sample 10 to be tested.
Fig. 7 is a block diagram of a determination device according to the present disclosure. In some examples, as shown in fig. 7, the determining device 30 may include a timing module 31. The timing module 31 may be used to synchronize the respective clock sections 13. Thus, the timing module 31 can ensure that the clock units 13 of the plurality of samples 10 to be measured are synchronized with each other.
In some examples, the timing module 31 may synchronize each sample 10 to be tested every predetermined period of time. Wherein the predetermined time period may be, but is not limited to, for example, 20min, 30min, or 1 h. The preset time period may be internally set by the judgment means 30. In addition, the preset time period may be fixed or adjustable. This can further ensure that the clock units 13 of the plurality of samples 10 to be measured are synchronized with each other.
Fig. 8 is a flowchart illustrating a synchronization method of a timing module of the determination device according to the present disclosure. In some examples, as shown in fig. 8, the synchronization method of the timing module 31 may include selecting one sample 10 to be measured as a standard sample (step S100), resetting the time of the clock part 13 of the standard sample (step S200), and synchronizing the time of each sample 10 to be measured based on the time of the standard sample (step S300).
Specifically, in step S100, the timing module 31 may select any one of the samples 10 to be measured among the plurality of samples 10 to be measured as the standard sample. In step S200, the timing module 31 may send a "reset time command" signal to the standard sample, and after the standard sample receives the "reset time command" signal, the corresponding clock portion 13 may be reset to implement time resetting of the standard sample. In step S300, the timing module 31 may transmit a timing signal to the standard sample. The standard sample may transmit the time of the corresponding clock part 13 to the timing module 31 after receiving the time signal. The timing module 31 can receive the time of the standard sample and synchronize the time of each sample 10 to be measured based on the time of the standard sample. Thus, the time synchronization of each sample to be measured 10 and the standard sample can be ensured.
In step S300, the timing module 31 may acquire the time of the clock part 13 of the standard sample and use the time of the clock part 13 of the standard sample as the target time in the time synchronization of each sample 10 to be measured. The timing module 31 may synchronize the time of each of the samples 10 to be measured other than the standard sample among the plurality of samples 10 to be measured to the target time. Thus, the time of each sample 10 to be measured can be further ensured to be synchronized with the target time of the standard sample.
In some examples, as shown in fig. 7, the determination device 30 may include a storage module 32. The storage module 32 may be used to store the device number, the MAC address, and the correspondence between the device number and the physical address. Specifically, the storage module 32 may store the MAC address of the sample 10 to be tested sent to the determination device 30. In addition, the storage module 32 may store a correspondence between the device number and the physical address, and the determination device 30 may assign a device number having a smaller number of bits than a prescribed number of bits of the physical address to each sample 10 to be tested, based on the physical address (MAC address) of the sample 10 to be tested and the correspondence in the storage module 32. Thus, the storage module 32 can facilitate the determination device 30 to store the device number, the physical address, and the correspondence relationship between the device number and the physical address.
In some examples, the storage module 32 may be a high-speed RAM Memory, a non-volatile Memory (non-volatile Memory) or a Read-Only Memory (ROM).
In some examples, as shown in fig. 7, the determining device 30 may further include a data checking module 33. The transmission data packet formed by the sample 10 to be tested may also include a check code. The data verification module 33 may verify the data of the electrochemical parameters in the transmitted data packet based on the verification code.
Specifically, the determination device 30 may send a data signal reporting instruction to the sample 10 to be tested. The sample 10 to be tested may send a transmission data packet to the determination device 30 after receiving the instruction. After the determining device 30 receives the transmission data packet, the data checking module 33 may check whether the content of the transmission data packet is correct, if the content is correct, the determining device 30 may feed back a "success signal" to the sample 10 to be detected, if the content is incorrect, the determining device 30 may feed back a "retransmission signal" to the sample 10 to be detected, and after the sample 10 to be detected receives the "retransmission signal", the transmission data packet may be retransmitted. Therefore, the correctness of the transmitted data packet can be ensured.
In some examples, the data checking module 33 may check in a manner selected from at least one of parity check, cyclic redundancy check, longitudinal redundancy check, gray code check, sum check, and xor check. Therefore, the correctness of the transmitted data packet can be further ensured.
In some examples, as shown in fig. 7, the determination device 30 may include a timing module 34. The timing module 34 may be used for timing. The determining device 30 may send a data signal reporting command to the sample 10 to be measured at a preset time or at set intervals, so as to obtain a transmission data packet of the sample 10 to be measured, and further perform the determination of the consistency of the electrochemical parameters. The timing module 34 may be a timing chip. The preset time or the set time may be internally set by the judgment means 30. In addition, the preset time or the set time may be fixed or adjustable.
Specifically, when the time of the timing module 34 reaches the preset time, the determining device 30 may send a data transmission signal (i.e. the above-mentioned "data signal reporting instruction") to the sample 10 to be tested. The sample to be tested 10 may receive the data transmission signal and transmit a transmission data packet including the reading time and the electrochemical parameter at the reading time to the determination device 30. Thereby, the determination device 30 can obtain the electrochemical parameters of each sample 10 to be measured at a preset time.
In some examples, the transmission data packet formed by the sample 10 to be tested may further include a reading time for reading the electrochemical parameter. Therefore, the transmission data packet obtained by the determination device 30 may be a transmission data packet including the device number, the electrochemical parameter, the reading time when the electrochemical parameter is read, and the check code of each sample 10 to be measured. After the determining device 30 receives the transmission data packet of each sample 10 to be measured, a plurality of waveform diagrams with the electrochemical parameters as longitudinal coordinates and the reading time as transverse coordinates can be formed based on the device number, the electrochemical parameters and the reading time in the transmission data packet, and the consistency of the electrochemical parameters obtained by each sample 10 to be measured can be determined according to the waveform diagrams.
In the present disclosure, the carrier 20 may have a receiving portion 21 for receiving a reaction solution and a holder 22 for holding a plurality of samples 10 to be measured. The sensing portions 11 of the plurality of samples to be measured 10 can detect electrochemical parameters of the reaction solution. The sample 10 to be tested may have a specified number of physical addresses and a memory 12 for recording electrochemical parameters. The determination device 30 may be connected to a plurality of samples 10 to be tested, and assign an equipment number having a number of bits smaller than a prescribed number of bits of the physical address to each sample 10 to be tested according to the physical address of the sample 10 to be tested. During the test, the sample 10 to be tested may send a transmission data packet containing the device number and the electrochemical parameters to the determination device 30. The determination device 30 may determine the consistency of the electrochemical parameters obtained from the respective samples 10 to be tested based on the transmission data packet. Under the condition, the corresponding electrochemical parameters of the samples 10 to be tested can be obtained according to the equipment numbers, so that the consistency of the electrochemical parameters of a plurality of samples 10 to be tested can be quickly judged, and the test efficiency of batch test is improved.
