Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of testing of biological analyzers, and particularly to a testing device for biological analyzers and a biological analysis kit. BACKGROUND
[0002] Biological analyzers, such as home blood glucose meters, uric acid detectors, total cholesterol detectors, blood ketone detectors, and the like, often store a certain number of measurement results, such as 500 groups or 1000 groups, for the convenience of users. However, in actual production of biological analyzers, due to faults or other factors, the upper limit of the number of stored measurement results of a biological analyzer may not reach the required calibration upper limit, so it is necessary to test each biological analyzer before it is shipped.
[0003] However, since the number of measurement results that can be stored by a general biological analyzer is relatively large, it takes a long time to test the upper limit, especially in the case of manual measurement, which requires a large amount of manpower and time. Therefore, how to improve the testing efficiency of the upper limit of the number of measurement results stored by a biological analyzer is very important for the manufacturer of the biological analyzer. SUMMARY
[0004] The main purpose of the present application is to provide a testing device for a biological analyzer, which aims to improve the testing efficiency of the upper limit of the number of measurement results stored by a biological analyzer.

The main control circuit is used to adjust the circuit parameters of the biological parameter equivalent circuit multiple times in the case that the second communication circuit is in communication connection with the first communication circuit, and after each adjustment, the main control circuit controls the biological analyzer to perform one measurement action based on the circuit parameters of the biological parameter equivalent circuit through the measurement end of the biological analyzer and through the second communication circuit and the first communication circuit. The main control circuit is also used to count the number of measurements when receiving a measurement completion signal transmitted by the biological analyzer, until the biological analyzer does not transmit the measurement completion signal. The measurement completion signal is transmitted by the biological analyzer after completing one measurement action, and the biological analyzer does not transmit the measurement completion signal at least after the number of stored measurements reaches the upper limit.
[0006] Optionally, the master circuit is configured to acquire a measurement type of the biological analyzer to be tested via the second communication circuit and the first communication circuit. The master circuit is further configured to determine a circuit parameter to be adjusted and a preset parameter generation rule based on the measurement type of the biological analyzer, and to adjust the circuit parameter multiple times based on the preset parameter generation rule.
[0007] Optionally, the biological parameter equivalent circuit includes a current source circuit configured to generate a test current flowing through a measurement end of the connected biological analyzer to enable the biological analyzer to perform a measurement based on the test current on the measurement end to complete a measurement action. The measurement type of the biological analyzer includes any one of blood glucose measurement, uric acid measurement, total cholesterol measurement, and blood ketone measurement. The master circuit is further configured to generate a current range of the corresponding test current and a corresponding preset parameter generation rule based on the measurement type of the biological analyzer. The master circuit is further configured to adjust the test current multiple times within the current range based on the preset parameter generation rule.
[0008] Optionally, the preset parameter generation rule includes a specific test current matched with the type of the biological analyzer, a number of test current levels, and a test current level interval.
[0009] Optionally, the test device of the biological analyzer further includes an input component electrically connected to the master circuit, and the input component is configured to connect a setting signal. The master circuit is further configured to set the specific test current based on the connected setting signal.
[0010] Optionally, the master circuit is further configured to set the number of test current levels based on an upper limit of the calibration storage times of the biological analyzer. The upper limit of the calibration storage times is positively correlated with the number of test current levels.
[0011] Optionally, a ratio of the upper limit of the calibration storage times to the number of test current levels is not less than 45.
[0012] Optionally, the master circuit is further configured to generate a first upper limit based on a preset percentage of the upper limit of the calibration storage times of the biological analyzer, and to set the number of test current levels based on the first upper limit, wherein the first upper limit is positively correlated with the number of test current levels.
[0013] The main control circuit is also used to set the test current to a preset first test current when the number of measurements reaches the first upper limit, and to control the bioanalyzer to perform a measurement action based on the circuit parameters of the bioparameter equivalent circuit every preset first time interval.
[0014] Optionally, the measurement completion signal may further include a measurement result signal; The main control circuit is further configured to, when the number of measurements has not reached the first upper limit, compare the current corresponding to each measurement result signal with the test current corresponding to the measurement action to generate a first difference percentage, and when the first difference percentage reaches a preset percentage, perform a fluctuation count and record the measurement result signal and test current corresponding to the first difference percentage.
[0015] This application also proposes a bioanalytical kit, including a bioanalyzer and a testing device for the bioanalyzer as described in any of the preceding claims. The testing device for the bioanalyst of this application includes a device body, within which are housed a main control circuit, a second communication circuit, and a bioparameter equivalent circuit. The main control circuit, when the second communication circuit is connected to the first communication circuit, repeatedly adjusts the circuit parameters of the bioparameter equivalent circuit. After each adjustment, it controls the bioanalyst to perform a measurement action at its measurement end based on the circuit parameters of the bioparameter equivalent circuit, via the second and first communication circuits. The main control circuit also counts the number of measurements upon receiving a measurement completion signal from the bioanalyst, until the bioanalyst stops transmitting a measurement completion signal. The measurement completion signal is transmitted by the bioanalyst after completing one measurement action, and the bioanalyst stops transmitting a measurement completion signal at least after the storage count reaches its upper limit. Through these settings, testers can automatically test the upper limit of the number of times test results can be stored in the bioanalyst using this testing device, eliminating the need for manual operation and effectively improving the efficiency of testing the upper limit of the number of times test results can be stored in the bioanalyst.

[0018] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.
[0019] To better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0020] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the attached figures). If the specific posture changes, the directional indicators will also change accordingly. It should be understood that although the steps in the flowcharts of the embodiments of this application are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Bioanalyzers, such as home-use blood glucose meters, uric acid meters, total cholesterol meters, and blood ketone meters, often store a certain number of measurement results, such as 500 or 1000 sets, for user convenience. However, in actual bioanalyzer manufacturing, malfunctions or other factors may cause the maximum number of storage times to fall short of the required calibration limit. Therefore, each bioanalyzer needs to be tested before leaving the factory.
[0021] However, since most bioanalysts can store a large number of measurement results, testing their upper limit requires a lengthy testing period, especially in manual measurements, which consumes significant manpower and time. Therefore, improving the testing efficiency for the upper limit of the number of times bioanalyst measurement results can be stored is crucial for bioanalyst manufacturers.
[0022] Therefore, this application proposes a testing device for a bioanalyst, which has a measuring end and a first communication circuit. It should be understood that the measuring end of a bioanalyst, such as a home-use blood glucose meter, uric acid analyzer, total cholesterol analyzer, and blood ketone analyzer, is one end of a test strip. One end of the test strip is connected to the bioanalyst, and the other end is used to contact the user's test solution. For example, in a blood glucose meter, the user will drop a drop of blood from their fingertip onto the outer end of the test strip inserted into the meter, allowing the bioanalyst to measure the user's blood glucose level. The first communication circuit can be implemented using a wired communication interface module, such as an RS485 communication module or a CAN communication module, or using a wireless communication module, such as a Bluetooth module or a WIFI communication module.
[0023] refer to Figure 1 In one embodiment of this application, the testing apparatus includes: The device body includes a main control circuit 10, a second communication circuit 20, and a biological parameter equivalent circuit 30. The second communication circuit 20 is used to communicate with the first communication circuit and is electrically connected to the main control circuit 10; The main control circuit 10 is used to adjust the circuit parameters of the bioparameter equivalent circuit 30 multiple times when the second communication circuit 20 is connected to the first communication circuit; and after each adjustment, the bioanalyst controls the bioanalyst to perform a measurement action through its measuring end based on the circuit parameters of the bioparameter equivalent circuit 30 via the second communication circuit 20 and the first communication circuit. The main control circuit 10 is also used to count the number of measurements when it receives the measurement completion signal transmitted by the bioanalyzer, until the bioanalyzer no longer transmits the measurement completion signal; The measurement completion signal is transmitted by the bioanalyzer after completing a measurement operation, and the bioanalyzer will not transmit the measurement completion signal at least after the storage limit has been reached.
[0024] In this embodiment, the main control circuit 10 can be implemented using a main controller, such as an MCU, DSP (Digital Signal Processor), FPGA (Field Programmable FPGA), or SOC (System On Chip). The second communication circuit 20 can be implemented using the same embodiment as the first communication circuit described above, so that the main control circuit 10 can establish a communication connection with the control unit in the biological analyzer under test through the second communication circuit 20 and the first communication circuit, which are electrically connected to it, thereby realizing data exchange.
[0025] Optionally, refer to Figure 2 In one embodiment, as described above, the working principle of the bioanalyst is to measure the parameter to be measured by detecting the current flowing through the end of the measuring terminal that is in contact with the liquid to be tested. Therefore, the circuit parameter in this embodiment can be the test current. The bioanalyst equivalent circuit 30 includes a current source circuit 31, which generates a test current flowing through the measuring terminal of the connected bioanalyst so that the bioanalyst can perform a measurement based on the test current at the measuring terminal to complete a measurement action. When the test device is inserted into the measuring terminal of the bioanalyst under test, it will be connected to the current source circuit 31 to form a complete current loop with the output terminal of the current source circuit 31. The main control circuit 10 can control the current source circuit 31 to output a test current through the measuring terminal so that the bioanalyst can complete a measurement action. (Refer to...) Figure 3 The current source circuit 31 can be implemented using a constant current output chip 311 and its peripheral circuits. The main control circuit 10 can output a corresponding control signal to the constant current output chip 311 to make it output a test current of a corresponding magnitude; or, refer to Figure 4 The current source circuit 31 can also be implemented by a constant voltage source circuit 313 and a series-connected adjustable resistor circuit 312. The constant voltage source circuit 313 outputs a stable first voltage, and the main control circuit 10 can adjust the test current by adjusting the resistance value of the adjustable resistor circuit 312.
[0026] Furthermore, it can be understood that the range of the parameters measured (i.e., the upper and lower limits of the test current as usable measurement results) is different for different types of bioanalysts. In other words, the multiple test currents required are different for different types of bioanalysts. Therefore, in one embodiment of this application, the main control circuit 10 is used to obtain the measurement type of the bioanalyst under test via the second communication circuit 20 and the first communication circuit; the main control circuit 10 is also used to determine the circuit parameters to be adjusted and the preset parameter generation rules based on the measurement type of the bioanalyst, and to adjust the circuit parameters multiple times based on the preset parameter generation rules.
[0027] In this embodiment, the measurement types of the bioanalyst include any one of: blood glucose measurement, uric acid measurement, total cholesterol measurement, and blood ketone measurement; the main control circuit 10 is further configured to generate a current range corresponding to the test current and a corresponding preset parameter generation rule based on the measurement type of the bioanalyst; the main control circuit 10 is further configured to adjust the test current multiple times within the current range based on the preset parameter generation rule. In one embodiment, the preset parameter generation rule includes: a specific test current matching the type of the bioanalyst (pre-set by the R&D personnel), the number of test current ranges, and the test current range interval (the magnitude interval of the current corresponding to adjacent test current ranges). In this embodiment, the main control circuit 10 generates multiple corresponding current values within the measurement current range of the bioanalyst (between the upper and lower limits of the specific test current) based on the required number of test current ranges and the test current range interval, and sets these multiple current values and the multiple current values corresponding to the specific test current as multiple test currents. (Referring to...) Figure 5 In one embodiment, the testing device of the bioanalyst further includes an input component 40, which is electrically connected to the main control circuit 10. The input component 40 is used to receive a setting signal. The main control circuit 10 is also used to set the specific test current based on the received setting signal. The input component 40 can be a trigger component, such as a button, installed on the bioanalyst and electrically connected to the main control circuit 10, or it can be a parameter of the corresponding specific test current transmitted to the main control circuit 10 via a second communication circuit 20 by a tester operating an external terminal.
[0028] Then, the main control circuit 10 sorts the multiple test currents from smallest to largest to generate a first sort. Based on this first sort, the current source circuit 31 adjusts the output of each test current from smallest to largest in a cyclical manner. Each time the control circuit adjusts the current source circuit 31 to output a test current, it controls the bioanalyst to perform a measurement action through its measurement terminal based on the circuit parameters of the bioparameter equivalent circuit 30. Upon receiving a measurement completion signal from the bioanalyst, the control circuit counts the number of measurements until the bioanalyst no longer transmits the measurement completion signal. When the main control circuit 10 has finished adjusting the current test current and has not controlled the bioanalyst to perform a measurement action, and has not received a measurement completion signal from the bioanalyst within a certain time (preset by the R&D personnel), the main control circuit 10 determines that the current measurement result of the bioanalyst has reached the storage limit. At this point, it can control the prompting components in the bioanalyst, such as a buzzer or LED light, to prompt the tester, allowing the tester to read the recorded number of measurements based on the testing device. This number of measurements is the corresponding upper limit for storing the test results of the tested bioanalyst. Thus, with the above settings, testers can use this testing device to automatically test the upper limit of the number of times test results can be stored in the bioanalyst without manual operation, effectively improving the efficiency of testing the upper limit of the number of times test results can be stored in the bioanalyst.
[0029] In addition, in one embodiment, the measurement completion signal further includes a measurement result signal, which is the measurement result generated by the bioanalyzer after performing the measurement action; the main control circuit 10 is also used to set the number of test current ranges based on the upper limit of the calibration storage times of the bioanalyzer; wherein, the upper limit of the calibration storage times is positively correlated with the number of test current ranges.
[0030] In this embodiment, the main control circuit 10 can also store and record the measurement results after each measurement action performed by the bioanalyst, so that testers or R&D personnel can subsequently read the measurement result data to determine the measurement accuracy of the currently tested bioanalyst. To ensure the accuracy and continuity of the measurement accuracy judgment, the main control circuit 10 sets a corresponding number of test current levels based on the upper limit of the calibration storage count, and the two are positively correlated. In one embodiment, the ratio of the upper limit of the calibration storage count to the number of test current levels is not less than 45. By ensuring that the ratio of the upper limit of the calibration storage count to the number of test current levels is not less than 45, that is, at least 2 test current levels need to be set for every 90 calibration storage counts, the situation where there are too few test current levels, which would prevent the accuracy of the bioanalyst's test current error, is not accurately measured, thereby ensuring the accuracy of subsequent error analysis. Of course, the ratio of test current levels should not be too high to avoid the error that occurs between two adjacent test current levels. In a specific implementation, if the difference in current values is too small to determine whether the test current is suitable for a large upper limit of the calibration storage count, the test current range can be set to no more than 30 ranges. Conversely, if the upper limit of the calibration storage count is small, the ratio of the upper limit of the calibration storage count to the test current range can be set to no more than 50. It's important to understand that, as described above, setting the number of test current ranges based on the type of bioanalyst and the maximum number of calibration storage cycles allows for the recording of measurement results at different points within the bioanalyst's measurement range. This enables manufacturers to understand the measurement accuracy of the bioanalyst at different points within its measurement range based on the multiple measurement results recorded by the testing device. However, since the number of test current ranges is based on the maximum number of calibration storage cycles, if the actual maximum number of storage cycles for the current bioanalyst has not been reached, some test current ranges may be missing measurements. For example, test current ranges corresponding to the upper and lower limits of the bioanalyst's measurement range may be missing, which is detrimental to manufacturers' analysis of the product's measurement accuracy. Furthermore, a larger number of test current ranges can slow down the testing process.
[0031] Therefore, in one embodiment of this application, the main control circuit 10 is further configured to generate a first upper limit of the number of calibration storage times based on a preset percentage of the upper limit of the number of calibration storage times of the bioanalyst, and to set the number of test current levels based on the first upper limit of the number of calibration storage times; wherein, the first upper limit of the number of calibration storage times is positively correlated with the number of test current levels.
[0032] The main control circuit 10 is also used to set the test current to a preset first test current when the number of measurements reaches the first upper limit, and to control the bioanalyzer to perform a measurement action based on the circuit parameters of the bioparameter equivalent circuit 30 every preset first time interval.
[0033] In this embodiment, the preset percentage can be set by the manufacturer based on experience. For example, based on production experience, if it is confirmed that the maximum number of storage cycles for the manufactured bioanalysts can reach 80% of the calibration storage cycle limit, then 80% can be used as the preset percentage. Then, the main control circuit 10 will generate the first maximum number of measurements based on the preset percentage of the calibration storage cycle limit of the bioanalyst, and will also generate multiple measurement ranges. This generation method can be set by the manufacturer in accordance with the requirements of the bioanalyst measurement accuracy judgment, as in the above embodiment.
[0034] Then, once the main control circuit 10 has determined that the number of measurements it has recorded has reached the upper limit for the first time, the measurement results from the multiple bioanalysts recorded by the main control circuit 10 basically meet the standard for judging the measurement accuracy of the bioanalysts, that is, the quantity meets the manufacturer's requirements for judging the measurement accuracy of the bioanalysts. Therefore, the main control circuit 10 will control the current source circuit 31 to always set the test current to a preset first test current (set by the R&D personnel according to requirements), and at preset first time intervals (set by the R&D personnel, for example, 1 second), control the bioanalyst to perform a measurement action based on the circuit parameters of the equivalent biological parameter circuit 30. This setting saves the time the main control circuit 10 spends adjusting the current source circuit 31, further reducing the total time for testing the upper limit of the number of test results stored for the bioanalysts. Furthermore, since there is no need to adjust the test current, it also ensures the stability and reliability of the measurement to a certain extent.
[0035] Furthermore, in one embodiment, the testing device of this application can also independently determine the accuracy of the measurement results provided by the bioanalyst. The main control circuit 10 is further configured to, when the number of measurements has not reached the first upper limit, compare the current corresponding to each measurement result signal with the test current corresponding to the measurement action to generate a first difference percentage, and when the first difference percentage reaches a preset percentage, perform a fluctuation count and record the measurement result signal and test current corresponding to the first difference percentage. The first difference percentage is set by the R&D personnel, for example, 80%, 90%, etc. This setting allows the manufacturer's R&D personnel to intuitively confirm the measurement accuracy of the currently tested bioanalyst while subsequently determining the upper limit of the number of times the current bioanalyst can store measurement results based on the testing device. This application also proposes a bioanalytical kit, including a bioanalyzer and a testing device for the bioanalyzer as described in any of the preceding claims.
[0036] It is worth noting that since the bioanalytical kit of this application includes the testing device of the above-mentioned bioanalytical instrument, the bioanalytical kit of this application also includes embodiments of the testing devices of all the above-mentioned bioanalytical instruments and the effects of each embodiment, which will not be repeated here.
