Blood glucose meter, also known as blood glucose meter, is an electronic instrument that measures blood glucose levels.The blood glucose meter is divided into two types: optoelectronics and electrode type.The testing principle of electrode blood glucose meters is more scientific, and the electrode can be hidden.
The working principle of the blood glucose meter
There are two differences in the principle of the blood glucose meter, one is the optoelectronics, and the other is the electrode type.The optoelectronic blood glucose meter is similar to a CD machine. It has a light -headed head. Its advantage is that the price is cheaper. The disadvantage is that the detection head is exposed to the air. It is easily polluted and affects the test results.Generally, it is relatively accurate within two years. After two years, it is recommended that patients who are using optical machines to calibrate at the repair station.EssenceGeneral hospitals have representatives of hospitals for regular maintenance, while the home blood glucose meter must go to the after -sales service department for bald maintenance.
The electrode -type testing principle is more scientific. The electrode is hidden in the electrode, which can avoid pollution. The error range is generally about 0.5.High accuracy and normal use, no calibration is required, long life.
There are two types of blood glucose meters from the blood collection method. One is blood type and the other is a blood -sucking type.Bloody machines are generally large, and patients are more painful.If the blood collection is too large, it will also affect the test results. Insufficient blood volume will fail, the operation will fail, and the test strip will be wasted. This blood glucose meter is mostly photoelectric.The blood sugar instrument, the test strip controls the blood samples itself, and will not have the results of the results due to the problem of blood volume. It is convenient to operate. Just click the blood droplets with the test strip.
Now most of the blood glucose meters are damaged, that is, the need to collect blood. For patients who need to measure blood glucose multiple times, there are no damaged blood glucose meters, but the price is very high! In order to reduce the pain of blood collection of fingertips, two arms are launched.Blood glucose meter.
Blood glucose meter operation method
The operation of the blood glucose meter is basically divided into five steps:
Step 1: Open the power supply, partly press the power switch directly, and partly inserts the test strip and automatically boot.
Step 2: Code adjustment.The encoding method of the blood glucose meter is divided into the following three types:
Manually enter the test strip Code, such as Lishin blood glucose meter, Johmniogen blood glucose meter;
插 Plug in the machine with a password chip to automatically record the test strip.
手Stocks are free of code, no manual or inserting chip, the instrument is automatically identified as Bayer Bayan Porsche 2. Aikle Shushu blood glucose meter.
Step 3: Bloody and blood -sucking: Blood recovery with the blood sugar meter can be used to use the blood collection pen, and then the blood dripped into the test strip. Most of the test strips are siphon, and it will be suck directly in the test strip blood -sucking area.
Step 4: Display results: After blood -sucking, the countdown will be presented to display the test result.Dont wait from 5 seconds to 30 seconds.
Step 5: Complete the test and shut down.The mainstream blood glucose meter unplug the test strip and shut down. Some of the early products also need to turn off the power button.Ship off can reduce battery consumption and machine loss.
How to maintain the blood glucose meter
1. When the blood glucose and blood glucose meter test notes are not used, please store it in the blood glucose test instrument package to keep or carry.
2. If the surface of the blood glucose instrument is sticky, do not clean it with strong corrosive alcohol, gasoline, etc.; you can use a neutral cleaning agent for wiping.Wipe with cotton wet (non -wet) water or alcohol.
3. Do not let any liquid enter the tester, and do not use a hair dryer to blow the tester.
4. Do not clean the slot of the gloves.
5. If the instrument work is not normal or damaged, please use it. Do not disassemble yourself.
6. Be careful to use the tester. If you pressure or huge vibration, it may damage the internal electronic performance of the instrument.
7. Do not clean the test strip slot at will.
8. Do not save it in a wet, overheated, too cold environment.The preservation of the blood glucose meter should avoid dust, the temperature should not be too high, and the humidity should not be too large.To prevent severe oscillation and collision.
