Painless Blood Glucose Meter

So far, Painless Blood Glucose Meter has gone through five stages of development in technology. The first three generations basically use the light reflection method to measure blood glucose concentration, and the fourth and fifth generations mainly rely on the electrochemical method. At present, the mainstream blood glucose meters in China use the electrochemical method. Compared with the fourth generation, the fifth generation has made some improvements in details such as micro-blood sampling and multi-site blood sampling. Admittedly, there is a tendency for blood glucose meters on the current market to be homogenized, and the basic functions are not much different. But how to measure more precisely and make it more convenient for patients to use has always been the common goal pursued by all companies. Mobile Internet, dynamic blood glucose monitoring, and non-invasive blood glucose monitoring are the three main directions of the current development of blood glucose meters. Mobile blood glucose meters make full use of mobile Internet technology, combined with mobile devices such as mobile phones and tablets, to give real-time analysis results and store them in the cloud, which is convenient for doctors and self-monitoring. Mobile blood glucose meter products are connected to mobile phones through the headphone jack, and the test results will be stored and processed through the mobile phone software, with multiple functions such as saving, automatic analysis, sharing and reminders.

Stability (CV value, coefficient of variation): Stability is an important indicator for evaluating the quality of Painless Blood Glucose Meter. Since the relative error of blood glucose meters is large, for example, if the blood glucose is 10, 8 or 12 can be considered accurate according to national standards. However, if two such results are measured by a machine, it means that the stability of the machine is not good. Poor stability will make the measurer at a loss and it is difficult to effectively guide the patient to take treatment plans. Therefore, the stability of the blood glucose meter is very important. A blood glucose meter with stable measured values ​​indicates that the stability of the test strip enzyme is good. Therefore, the more advanced the enzyme cultivation technology, the better the stability of the manufacturer's products.
Accuracy (SD value, standard deviation, correlation coefficient): As long as the test strip has good stability, the measured value can be adjusted by adjusting the password to make it as close to the standard value as possible, which is the so-called calibration. The premise of accuracy is stability. Without stability, there is no accuracy at all. The calibration standards and technologies of each manufacturer will be different. Products with good accuracy represent good calibration technology of the manufacturer.

 

Test strip storage: Blood glucose test strips should be placed in a dry place at +10 degrees and +40 degrees. Do not place them in the bathroom or kitchen, let alone in the refrigerator, as these places are very susceptible to moisture. If they have been placed in the refrigerator, the sealed test strip tube must be placed in room temperature and slowly heated up until it reaches room temperature before use. Do not remove the test strip before the test strip tube reaches room temperature to avoid condensation in the test strip tube. Patients living in some relatively humid places (such as the south) should pay attention to the following: Each time a test strip is taken out, the sealed cover of the test strip tube should be immediately closed to prevent the test strip from getting damp; a new tube of test strips should be used up within three months as much as possible; if possible, try to buy blood glucose test strips with individual packaging.

 

Setting password technology: As a biochemical product, the cultivation process of glucose oxidase (hereinafter referred to as enzyme) is very complicated, so the characteristics of each batch of enzymes will be different, so the current generated will be slightly different. In order to make the measurement results of each batch of test strips as close to the standard value as possible, researchers will adjust the differences between different batches of test strips by setting passwords to make each batch of test strips as close to the standard value as possible. Therefore, it is very important to set the correct password. The enzyme cultivation and coding technology of each manufacturer is different, so it will affect the quality of each product.
Batch difference: Since the production process of blood glucose test strips has very strict environmental requirements, manufacturers will make the measured values ​​as close to the standard value as possible through calibration, but the differences between different batches of test strips must be larger than the differences between the same batch of test strips. This is the batch difference; that is, the stability of the same batch of test strips is usually better than the stability between different batches. Our national standard requires that the batch difference is not more than 15%.

As a diabetic patient, monitoring blood sugar and understanding blood sugar changes in the body can affect our entire treatment. How much error is acceptable often becomes the focus of attention. Multiple data from the World Health Organization and the U.S. Food and Drug Administration show that if the test error of the blood glucose meter is within 20%, it will not affect the patient's treatment plan. For example, three consecutive blood sugar measurements were 6.4mmol/l, 5.5mmol/l, and 5.9mmol/l respectively. Although the numbers are not exactly the same, it can be seen that blood sugar is well controlled, so there is no need to change the treatment plan.

Temperature compensation technology: Since enzymes are active, generally the activity of enzymes does not change much above 20 degrees. Below 20 degrees, the lower the temperature, the worse the activity. When the activity deteriorates, the current generated when reacting with glucose will become smaller, which will make the measurement result lower. In order to measure accurate blood sugar values ​​at different temperatures, R&D personnel will use thermistors to adjust the instrument resistance value according to the real-time temperature conditions, so that the enzyme and blood can produce currents that match the blood sugar value at different temperatures as much as possible, and then obtain the correct blood sugar value. This is the temperature compensation of the blood glucose meter. Since the formulas of blood sugar test strip enzymes of different manufacturers are different, each company will set the temperature compensation parameters according to the characteristics of each test strip enzyme. However, since the characteristics of the enzyme are difficult to grasp, the temperature compensation effects of each company are uneven. In general, the closer the results measured under different temperature environments are, the more advanced the temperature compensation technology of the manufacturer's products is.
Applicable temperature: Since enzymes are affected by temperature, blood sugar can only be measured under certain temperature conditions. The temperature compensation technology of each manufacturer not only determines the high and low temperature stability, but also determines the applicable temperature range of the blood glucose meter. The operating temperature of each blood glucose meter is slightly different, generally between 10-40 degrees.
