Description
Technical Field
The invention relates to the field of In Vitro Diagnostic (IVD), In particular to a sensor identification method and device and an object to be tested test device.
Background
Chemical sensors are devices that convert chemical signals into analyzable signals, and the chemical information may be the concentration of a particular sample or the total composition. Chemical sensors typically comprise two basic components in series: a chemical identification system and a physicochemical energy converter. Chemical sensors have found wide application in the field of engineering. A biosensor is a special chemical sensor that uses a bio-sensitive element to recognize a signal, and an electrochemical sensor is widely used in IVD.
The purpose of identifying the model of the electrochemical sensor is as follows: firstly, under the condition that the testing device can only test a single sensor, in order to prevent different types of electrochemical sensors (such as blood sugar, blood ketone, creatinine, uric acid and the like) from being inserted into the same detection device (instrument) to cause wrong detection, the sensors which are not matched with the testing device are subjected to error reporting processing or non-detection processing; and secondly, under the condition that the same testing device tests various sensors (different objects to be tested, such as blood sugar, blood ketone, creatinine, uric acid and the like), the correct measuring mode and calculation method are selected by identifying the model of the sensor. At present, the identification of the model of the electrochemical sensor is usually realized by triggering different I/O ports, after the sensor is inserted into a detection device, the detection I/O port is short-circuited to a reference ground plane to realize starting, and the model of the sensor is judged by different short-circuited positions on the sensor. Due to the limitation of the sensor production process (screen printing or laser after whole plate electroplating), the number of PINs of the connector PIN between the sensor with the same width and the detection device is limited, taking a 4PIN sensor structure model and the connector (socket) as an example: at most, 4 PINs support the identification of 3 types of sensors, and these three types of sensors are difficult to test in the same test apparatus.
The identification types of the existing sensor models are limited, if the sensor types are increased, other modes such as adding PIN PINs of a test strip and a socket are needed, but the sensor with the same electrode width is difficult to realize due to the limitation of the production process. The sensor model is limited under the condition that the detection device has the same number of electrodes; and the detection device has limited identifiable sensor types under the same sensor model, and cannot measure various objects to be measured.

With reference to the above embodiments and fig. 2, the sensor identification device is described in detail as follows;
the electrodes of the sensor are made of conductive materials such as carbon, silver and gold through screen printing (electroplating and laser), so that the electrodes have resistors, the sensor starting positive electrode interface 201 and the sensor starting negative electrode interface 202 also have resistors, the equivalent resistors of the sensor electrodes, the sensor starting positive electrode interface 201 and the sensor starting negative electrode interface 202 are R2 and R3, and the resistors R2 and R3 have different resistance values (R2 and R3 are equivalent resistors on the electrodes 1 and 2) due to the fact that the conductive materials used for the sensor electrodes are different; also, the difference in length and width of the sensor electrodes causes the R2 and R3 resistances to be different.
After the sensor startup positive electrode interface 201 and the sensor startup negative electrode interface 202 detect that the sensor is inserted, the equivalent circuit diagram is shown in fig. 3, if two different materials, namely a carbon electrode and a silver electrode, are adopted, the carbon electrode corresponds to the sensor a, and the silver electrode corresponds to the sensor b; the resistance of the carbon electrode material is large, for example, R2+ R3 is 2000 Ω, the resistance of the silver electrode material is small, for example, R2+ R3 is 20 Ω, the pull-up resistor R1 is fixed to 10000 Ω, after the sensor is inserted into the testing device, the signal interface 205 detects voltage, the detected voltage is VCC (R2+ R3)/(R1+ R2+ R3), the voltage detected by the carbon electrode sensor a is VCC/6, and the voltage detected by the sensor b is VCC/5001, so that two different sensors can be easily distinguished; if two sensors use carbon electrodes, the length of the electrodes is changed (the width is equal, the equivalent resistance of the electrodes is proportional to the length of the electrodes), the total length of the electrode 1 and the electrode 2 of the sensor A is 1cm, the total length of the electrode 1 and the electrode 2 of the sensor B is 1.5cm, if the equivalent resistance on the sensor A is R2+ R3 is 2000 omega, the equivalent resistance on the sensor B is R2+ R3 is 3000 omega, and the pull-up resistance R1 is 10000 omega, so that the voltage detected by the signal interface 205 after the sensor A is inserted into the detection device is VCC/6, and the voltage detected by the signal interface 205 after the sensor B is inserted into the detection device is 3VCC/13, thus two different sensors can be easily distinguished; if two kinds of sensors use carbon electrodes, the width of the electrode is changed (the length is equal, the equivalent resistance of the electrode is inversely proportional to the electrode width), the electrode width of the sensor A is 2mm, the electrode width of the sensor B is 4mm, if the equivalent resistance of the sensor A is R2+ R3 is 2000 omega, the equivalent resistance of the sensor B is R2+ R3 is 1000 omega, the pull-up resistance R1 is fixed to 10000 omega, after the sensor A is inserted into the detection device, the voltage detected by the signal interface 205 is VCC/6, and after the sensor B is inserted into the detection device, the voltage detected by the signal interface 205 is VCC/11, thus two kinds of different sensors can be easily distinguished.
The signal processing unit obtains the interface voltage through the signal interface 205, and because the material, the length and the width of the electrode are different, the resistance values of R2 and R3 are different, the interface voltage value read by the signal interface 205 is different, and the corresponding sensor models are different, the purpose of test strip model can be achieved by adjusting the material, the length and the width of the electrode, namely, the same sensor model can measure various objects to be measured only by adjusting the resistance values of R2 and R3. The signal processing unit 206 converts the interface voltage into an interface signal through analog-to-digital conversion, the sensor identification unit 208 queries the corresponding sensor model in the sensor model comparison table according to the interface signal, the sensor model comparison table is generated in advance by the sensor model comparison table generation unit 209, and the generation process is as follows: the sensor model comparison table generating unit 209 obtains the voltage value of the power supply unit 203, the pull-up resistance value of the pull-up resistor 204, and the electrode equivalent resistance value and model of the training sensor, calculates an interface signal of the training sensor according to the voltage value, the pull-up resistance value, and the electrode equivalent resistance value, and generates a sensor model comparison table according to the interface signal and model of the training sensor.
