Electronic blood glucose meter, also known as electronic blood glucose meter, is a smart electronic medical instrument that conveniently tests its own blood sugar index, and is generally suitable for people with high blood sugar. It mainly includes a blood glucose meter, a test paper and a needle. The needle is used to puncture the ring finger to collect blood. The test paper is used to inhale the sample blood and connect to the blood glucose meter. The blood glucose meter obtains the blood glucose index through the test paper.

The key technology is the batch difference. During the production process, the blood glucose meter has strict requirements on the environment and the manufacturer. The manufacturer will use the calibration measurement to be as close to the standard value as possible. However, the difference between the tests of different batches must be more than The difference between them is large, which is different from the group. It is usually tested in the same batch, and the stability is better than the stability between different batches. The batch difference requires that our national standard is not more than 15 %. As long as the accuracy of the glucose meter test paper is good, the measured value of the password can be adjusted to the standard value by adjusting the password. This is also called calibration. The accuracy is stable and stable. It cannot be simply inaccurate. Manufacturers have different Accurate calibration standards and techniques, good product manufacturer calibration techniques. Stable blood glucose meter, such as glucose is a relative error of 10 meters long, an important indicator of evaluation, according to national standard measures, 8 or 12 can be considered accurate, but measured by machine and other two results, explain The machine has good stability, the measured stability is poor, and I do n’t know where to go. It is difficult to effectively guide patients to take treatment, so that the stability of the blood glucose meter is very important. The measurement value explanation is the stability of the stable glucose meter test enzyme . Therefore, product manufacturers with more advanced enzyme culture technology have better stability. Set the password technology because it is a biochemical product, the training process of glucose oxidase (hereinafter referred to as enzyme) is very complicated, so the nature of each batch of enzymes has certain differences, so there can be slightly different at present, so that each The batch test result and the standard value are as close as possible. The researchers will try each batch of test paper with a standard value close to the standard value through the set password test paper. The difference between different batches is adjusted. Therefore, it is very important to set the correct password. Importantly, each manufacturer's cultural enzyme and coding technology are different, so it will affect the quality of the product. Temperature compensation technology enzymes have little change in activity. Generally, enzymes with an activity above 20 degrees Celsius, below 20 degrees, the lower the temperature, the lower the activity. The current generated during the activity and glucose reaction is a small change, so that the measurement result is low, the purpose is to accurately measure the blood glucose value at different temperatures, R & D personnel adjust the resistance of the device according to the real-time temperature through the thermistor The value, which makes it possible that enzymes and blood at different temperatures can generate a current that matches the blood sugar value, and then get the correct val
