Description

How to set instrument parameters

technical field

The invention relates to a parameter setting method and device, in particular to a parameter setting method and device for a detection instrument.

Background technique

Biosensors are important instruments for diagnosing and monitoring diseases. Such detectors usually need to be equipped with biosensor test strips for detection. For example, self-monitoring blood glucose monitors (SMBG) need to be equipped with blood glucose test strips to complete the detection of blood sugar concentration. The sensing test strips used in this type of biosensor are usually consumables for one-time use, and the user purchases each unit of the biosensor test strip, and the necessary or relevant information of the sensing test strip may need to be input into the biosensor , so that the instrument can operate correctly and output accurate test results, or further achieve the role of system management. Such information may include: test strip calibration parameters, sensing function information, test strip expiry date information, and other information that needs to be input into the testing instrument. In particular, the calibration parameters of the test strips are the information that must be input when the current self-monitoring biodetector is used for detection. (Lot-by-lot) characteristic difference, in order to reduce the difference reflected in the test results, the characteristics of each batch of sensory test pieces manufactured will be represented by an equation, and the representative will be given according to the coefficient of the equation Correction parameters for the characteristics of the batch of test strips. The characteristic equation used is usually a binary linear equation, as shown in Equation 1, and the slope (a) and intercept (b) of the characteristic curve are its calibration parameters. Right now

y=ax+b Equation 1

The manufacturer of the biosensor test strip must attach the slope and intercept values of the characteristic curve to the batch of test strips when outputting the test strips, which is called a calibration code (Calibration code). Before starting to use each batch of test strips for measurement, the user must first set the procedure according to the user manual, so that the testing instrument can obtain correct calibration information to obtain correct measurement results.

There are currently two known calibration value setting procedures. One is that the user selects a corresponding set of calibration codes built in the instrument memory according to the calibration codes marked on the packaging of the batch of test pieces. Another way is that the manufacturer attaches a calibration code memory card (code card) when each batch of test pieces leaves the factory. The memory card uses a memory (usually EEPROM) to store the calibration parameters. When the user transfers the calibration code before measurement When the memory card is inserted into the instrument, the instrument will read the calibration parameters of the memory unit on the memory card to the instrument, so that the instrument can obtain the calibration data corresponding to the batch of test pieces.

In the above-mentioned first method, since the calibration parameters need to be determined in advance and recorded in the memory of the testing instrument, the number of groups of the calibration data is limited by the size of the memory space, and the characteristics of each batch of test strips manufactured in the future must be It is one of the calibration parameters built in the instrument, which directly affects the production pass rate of the sensory test piece, and it is impossible to make the original testing instrument continue to be applicable after improving or modifying the characteristics of the test piece. In addition, such a setting method needs to be set by the user, which is inconvenient to use, and if the setting is wrong due to negligence, it will cause wrong interpretation of the measurement.

However, the setting method using the calibration code memory card does not have the first setting because the calibration parameters are stored on the accompanying calibration code memory card before each batch of test strips leaves the factory. The problem caused by the method, because this method records the calibration parameters in the calibration code memory card attached to each batch of test pieces, it will not be limited by the memory space of the instrument itself, and will not affect the produced test pieces. Features impose limitations. However, such an approach requires a calibration code memory card to be attached to each batch of test pieces, and the memory card contains at least one memory unit, which greatly increases the cost.

The two methods mentioned above cannot simultaneously achieve the considerations of the possibility of detecting changes in the characteristics of the test piece, improving the pass rate of test piece production, fast setting, low cost, and increasing the convenience of setting. Therefore, there is a need for a parameter setting method and device that can achieve all the above-mentioned purposes.

Detailed ways

It should be noted that although exemplary embodiments are provided as examples throughout this discussion, alternative embodiments may incorporate aspects without departing from the scope of the invention.

Fig. 1 is a detection instrument according to an embodiment of the present invention. As shown in FIG. 1 , the detection instrument 100 includes a parameter setting card 110 , a connection port 120 , a control unit 130 , a sensing unit 140 , a display unit 150 and a user control interface 160 . The detection instrument 100 may be an instrument with the function of biological detection, which reads the data in the parameter setting card 110 through the connection port 120, and the control unit 130 can perform parameter correction according to the read data.

FIG. 2 shows the parameter setting card 110 , the connection port 120 and the control unit 130 as in FIG. 1 . On the parameter setting card 110, strip areas 241, 242, 243 and 244 are configured; first block area groups 251, 252; and second block area groups 253 and 254, each block area group includes Multiple blocky areas. In this embodiment, each block area group includes 5 block areas. The control unit 130 has two input ports A, B and the grounding point GND; the pin 211 is connected to the high potential VDD and the input port B; the pin 212 is connected to the grounding point GND; and the pin 213 is connected to the high potential VDD and the input port a. The bar area and the first group of block areas on the parameter setting card 110 respectively correspond to each pin of the connection port 120 . It can be seen from FIG. 2 that the first block-shaped area group 251 corresponds to the pin 211 ; the bar-shaped area 241 corresponds to the pin 212 ; and the first block-shaped area group 253 corresponds to the pin 213 . The strip area 241 extends to the rear end of the parameter setting card 110, and is connected to each block area in the second block area group 253 and 254 via a plurality of wires 260-269. FIG. 3 is a back view of the parameter setting card 110 , from which it can be seen that each block area in the first block area group 251 and 252 is connected to each block area in the second block area group 253 and 254 .

Figures 4 and 5 show the process of inserting the parameter setting card 110 into the connection port 120. Through this insertion process, each pin of the connection port 120 can read logic changes, that is, the different high and low potentials connected to each block area. High/Low change. And each logical change represents a specific data meaning, so that the detection instrument 100 can perform corrections or perform other functions according to the specific data meaning. The meaning of the specific data is written into the parameter setting card 110 by means of programming, and the steps of programming are very simple, which is different from the method of finally writing the data into the memory in the prior art. The programming of the parameter setting card 110 only needs to cut the wires 260-269 between the second block area groups 253 and 254 and the strip area 241, so that the first block area groups 251 and 252 represent specific logic changes. For example, if the wires 260 and 262 are cut off, then after the parameter setting card 110 is fully inserted into the connection port 120, the logic change read by the pin 211 is "low, low, high, low, high", if Binarizing this yields "00101"; also, if wires 266, 267 and 269 are cut, pin 212 then reads "10110". It can be seen that the preset value of each block area is "0", and the block area can be set to "1" by cutting off the wiring corresponding to the block area. Using this method, the external data can be programmed in the parameter setting card 110 and input into the testing instrument 100 to achieve functions such as parameter calibration. In order to ensure that the logic state read by the instrument is correct, it can be checked by using the characteristics of the inverted signal when the setting card is inserted and removed. If the logic state is "10110" when plugged in, it should be "01101" when unplugged. If the two are different, it means that the process of setting the card input is wrong, and the user can be prompted to re-operate accordingly.

The parameter setting card 110 in the present invention can also use the same method to input other external data into the instrument. The programming of the parameter setting card 110 can be realized by using a PCB engraving machine, which is not only low in cost but also fast in processing, saves the high cost of using memory in conventional techniques, and avoids the inconvenience of users selecting correction codes. Such automatic coding (auto -coding) can also become another correction system independent of the patented technology of the code memory card.
