Portable Glucometer

Electronic blood glucose meter, also known as electronic blood glucose meter, is a convenient intelligent electronic medical instrument for testing your own blood sugar index, which is generally suitable for people with high blood sugar. It mainly includes blood glucose meter, test strip and needle, the needle is used to puncture the ring finger to collect blood, the test strip is used to inhale the sample blood, and it is connected to the blood glucose meter, and the blood glucose meter obtains

Blood glucose meter in the production process of the environment and strict requirements, the manufacturer will be as close as possible to the standard value through calibration measurement, but the difference between different batches of tests, the same batch of test strips must be more than the difference between the differences, which is the difference between the group, it is usually the same batch of testing, the stability is better, than the stability between different batches, the batch difference requires that our national standard is not more than 15%.

precision

As long as the blood glucose meter test strip has good stability, the measured value can be adjusted to be close to the standard value, which is also called calibration, the accuracy is stable under the premise that it cannot simply be inaccurate, the manufacturer has different accuracy calibration standards and technologies, good product manufacturer calibration technology.

stability

Stable blood glucose meter, such as glucose is 10 meters long relative error, an important indicator of evaluation, according to the national standard measures, 8 or 12 can be considered accurate, but measured by the machine and other two results, indicating that the stability of the machine is good, the stability of the measurement is poor, do not know where to go, it is difficult to effectively guide the patient to take treatment, so that the stability of the blood glucose instrument is very important, the measurement interpretation is stable blood glucose meter test enzyme stability. Therefore, manufacturers of products with more advanced culture enzyme technology have better stability.

Set up password technology

Because it is a biochemical product, the training process of glucose oxidase (hereinafter referred to as the enzyme) is very complex, so the properties of each batch of enzymes have certain differences, so there can be slightly different at present, so that each batch of test results and the standard value are as close as possible, the researchers will try each batch through the set password test strip to close to the standard value of the test strip, the difference between different batches to adjust, so it is very important to set the correct password, each manufacturer's cultural enzyme and coding technology is different, So it affects the quality of the product.

Temperature compensation technology

Enzymes are enzymes whose activity does not change much, generally above 20 degrees Celsius, and below 20 degrees, the lower the temperature, the lower the activity is poor. Activity and glucose reaction when the current is produced is a small change, so that the measurement result is low, the purpose is at different temperatures, can measure the accurate blood glucose value, R&D personnel according to the real-time temperature adjustment device resistance through the thermistor value, which makes it possible at different temperatures of the enzyme and blood can generate and blood glucose value to match the current, and then get the correct value, which is the blood glucose meter temperature compensation. Because each manufacturer's blood glucose test strip enzyme preparation is different, so the characteristics of the temperature compensation parameters of the paper are set according to the enzyme, but because it is difficult to grasp the characteristics of the enzyme, the temperature compensation effect caused by it is generally uneven, and the measurement results at different ambient temperatures are closer to the representatives of the manufacturer, and the more advanced product temperature compensation technology.
