Test mode
The test mode of the blood glucose meter is very important. The full automation of the test process means that the blood glucose meter can automatically start up after inserting the blood glucose test strip, enter the test program to display the test results after adding the blood sample, pull out the test strip to automatically shut down and automatically store the test results. This blood glucose meter is simple to use and helps to provide more accurate test results.
Button
Sometimes patients need to adjust the calibration code, query the stored results and delete the stored results. Therefore, it is necessary for the blood glucose meter to have an appropriate number and size of buttons with clear function differentiation.
Power Supply
The blood glucose meter usually needs enough voltage to ensure the normal operation of the chip. Therefore, its power supply generally uses button batteries or even special batteries. However, it is difficult to replace button batteries and special batteries, which makes some blood glucose meters unable to work normally after purchase. Some blood glucose meters can use a common No. 7 battery, which is more convenient to use.
Memory storage
After the test, the memory storage of the test results is helpful to understand the blood glucose changes of the patients over a period of time. Therefore, appropriate storage capacity is very necessary.
Automatic correction
Whether electrochemical method or photochemical method, enzymatic reaction is the basis of the test. The enzyme reaction is greatly affected by temperature. Therefore, it is better to have a built-in temperature sensor in the blood glucose meter, which can automatically correct the temperature to ensure that the test results are not affected by the temperature during the test.
Blood glucose test strip
The blood glucose test strip is very sensitive to the humidity environment, and the test value will be inaccurate after the test strip is damped. Therefore, most bottled test strips require that the test strips must be used up within three months after opening the test strip bottle, and each time the bottle cap is opened, it is required to be very fast. Therefore, individual users had better choose the test strip of single package.
display
The size of the blood glucose meter shall meet the needs of operation during the test, and it is not advisable to be too large or too small. It is better to hold it stably with one hand and test the operation conveniently. At the same time, a properly sized blood glucose meter can ensure that a large enough display screen can be provided, so that even middle-aged and elderly patients do not have to worry about not being able to see the test results clearly.
Price
The price is not the most important factor in the purchase of blood glucose meters. The key is the quality. However, generally, good blood glucose meters are around 1000 yuan, which is an additional burden for many families and needs to be comprehensively measured. In fact, the price of the test strip is more important. The instrument is a one-time cost, but the purchase of the test strip is long-term. Choosing a test strip that can stabilize long-term supply and has an economical price can save a lot of economic expenses.
