The following information is expected to help you choose a blood glucose meter:
Blood glucose meter selection 10 component.
As we all know, diabetes is not terrible, but its complications. A large number of studies show that the occurrence of diabetic complications can be greatly reduced by effectively controlling blood sugar levels. Regular blood sugar monitoring at home for diabetic patients is the basis for guiding them to effectively control their blood sugar levels.
At present, there are many blood glucose meters on the market, which makes people see things in a blur. How to choose a reliable blood glucose meter? The following 10 points should be considered when purchasing a blood glucose meter.
Testing principle
There are two main principles of blood glucose meter: photochemical method and electrochemical method. Photochemical blood glucose meter is similar to CD machine, with photoelectric head. This kind of blood glucose meter is relatively cheap, but the probe is exposed to the air, which is easy to be polluted and affects the test results. The error range is plus or minus 0.8. Therefore, the smooth hole must be cleaned frequently, and it is recommended to go to the maintenance station for calibration after two years of use. The electrochemical blood glucose meter can avoid pollution, and the error range is 0.2. During normal use, calibration is not required.
Blood collection method
The blood glucose test paper used for blood glucose testing is specially matched with various brands of blood glucose meters and cannot be used universally among brands. At present, there are two blood sampling methods for blood glucose test paper on the market: drop blood type and siphon type. Blood drop blood glucose test strip needs a large number of blood samples when testing, and it needs to be dripped on the test strip. Too many, too few or inaccurate blood drops will affect the detection value. However, the blood glucose test paper using siphon automatic blood drawing mode needs less blood samples, and the sample addition amount can be automatically controlled. The test paper has a confirmation point, which can show whether the blood is suitable or not, and the operation is simple, which can also avoid the mistake of adding blood samples and ensure the accuracy of the test results.
Test modes and buttons
The test mode of blood glucose meter is very important. The automatic test process means that the blood glucose test paper can be automatically opened, the blood sample can be added to the test program to display the test results, the test paper can be automatically closed, and the test results can be automatically saved. This blood glucose meter is easy to use and helps to provide more accurate test results.
Sometimes patients need to adjust the correction code, query the stored results and delete the stored results. Therefore, the blood glucose meter must have an appropriate number and size of buttons and clear functions.
Power?Supply?
In the test of blood glucose meter, it is generally necessary to have enough voltage to ensure the normal work of the chip. So its power supply is generally button cell, or even a special battery. However, it is difficult to replace button cell and special batteries, resulting in some blood glucose meters not being used normally after purchase. At present, some blood glucose meters can use 1 ordinary No.7 battery, which is convenient to use.
Memory storage function of test results
After the test, the memory storage of the test results is helpful to understand the changes of blood sugar in patients for a period of time. Therefore, appropriate storage capacity is very necessary.
Automatic temperature correction kinetic energy
Whether electrochemical method or photochemical method, enzyme reaction is the basis of detection. The reaction of enzymes is greatly influenced by temperature, so it is best to build a temperature sensor in the blood glucose meter, which can automatically correct the temperature and ensure that the test results are not affected by temperature during the test.
Packaging method of blood glucose test strip
Blood glucose test paper is sensitive to the preserved humidity environment, and the test value will be inaccurate after the test paper is wetted. Therefore, most bottled test paper requires that the test paper must be used up within three months after opening the test paper bottle, and it is required to open the bottle cap quickly every time. Therefore, it is best for individual users to choose a single package of test paper.
Size of display screen
The size of the blood glucose meter should meet the needs of operation during testing, and should not be too large or too small. It is better to hold it firmly with one hand and facilitate the test operation by yourself. At the same time, a proper size blood glucose meter can ensure a large enough display screen, so even middle-aged and elderly patients don't have to worry about not seeing the test results clearly.
price
In the purchase of blood glucose meters, the price is not the most important, the key is the quality, but generally better blood glucose meters are around 1,000 yuan, which is also an extra burden for many families and needs to be comprehensively measured. In fact, the price of test paper is more important. The instrument is a one-time cost, but the purchase of test paper is long-term. Choosing test paper with stable long-term supply and economical price can save a lot of economic expenses.
after service
It is necessary to know the after-sales service of the blood glucose meter and whether the test paper supply is in place to prevent the situation of "cooking without rice".
Considering the above factors comprehensively, I believe you can definitely buy an accurate, simple and economical blood glucose meter suitable for your own use.
Guide to purchasing blood glucose meter
Since the invention of Tom Clémence in 1968, the blood glucose meter has gone through different stages of technical development, including portable blood glucose meter, dynamic blood glucose meter, surface blood glucose meter and so on. Now most of our diabetics buy portable blood glucose meters. So, how to choose a blood glucose meter according to your own needs?
There are "five stages" in the development of blood glucose meter, but the working principle of blood glucose meter is two different, one is photoelectric and the other is electrode.
The photoelectric blood glucose meter has a photoelectric head, but the probe is exposed to the air, which is easy to be polluted and affects the test results. The service life is relatively short, generally accurate within two years, and it needs to be calibrated regularly after two years. The principle of electrode type test is scientific, and the electrode mouth is hidden, which can avoid pollution and make the test intensive reading higher. Under normal use, no calibration is needed, and the service life is long.
At present, most blood glucose meters are broken, that is, blood is needed to determine the blood glucose value. Although there is no broken blood glucose meter, it is expensive and the maintenance cost is quite amazing, so most patients will not consider this. Blood-collecting portable blood glucose meter has two blood-collecting methods, one is blood-dropping type (also called blood-smearing type) and the other is blood-sucking test.
Blood-dropping blood glucose meter generally needs to take a lot of blood, which is very painful, and the patient is more painful. This kind of blood glucose meter should master the amount of blood collected. If too much blood is collected, it will affect the test results. If the amount of blood drawn is not enough, the test paper for operation failure will be wasted. This kind of blood glucose meter is mostly photoelectric. At present, the most popular blood glucose meters on the market are Johnson & Johnson's stable doubling type and Roche Le Kang's full range of blood glucose meters.
Blood glucose meter, test paper will control the blood volume by itself, and there will be no deviation because of the blood volume problem, which is convenient to operate. Contact the surface of blood drops with test paper. At present, there are many blood glucose meters on the market, such as Johnson Steady, Easy Test, Roche Superior, Kyoto 1640, Yicheng JPS5, Abbott's blood glucose meters (including Portugal).
The technology of blood glucose meters is no secret at present, so there are many blood glucose meters on the market, especially some blood glucose meters produced in Taiwan Province Province. All blood glucose meters have 20 or 30 brands, such as Johnson & Johnson, Roche, Kyoto, Abbott, Yicheng, Sannuo, Huihao, Reid, Dr. Tang, Braun, Bayer, McDonnell Douglas, Shijiale and Taixin. The blood glucose meter market will face the final reshuffle.
In fact, the imported blood glucose meter has basically solved the problem of accuracy. Even the JPS5 blood glucose meter produced by Beijing Yicheng, if strictly operated, will not exceed 10% compared with the blood glucose value of venous blood (at present, the State Pharmaceutical Administration has not formulated a unified performance standard, and there is no clear standard to specify the error range of the blood glucose meter). Of course, the results of all home blood glucose meters can only be used as clinical reference.
So how do we choose a blood glucose meter according to our own needs? The general direction has the following points for reference:
(1) For patients who seldom measure their blood sugar (diabetic patients need to monitor their blood sugar more if their blood sugar is not well controlled or their treatment methods need to be changed), I think we can use individually packaged test paper to facilitate storage, and it will not affect the test results for a long time during normal storage time. Such blood glucose meters include Kyoto, Abbott and Yicheng blood glucose meters.
(2) For patients who are afraid of pain due to frequent blood glucose measurement, they can choose a blood glucose meter with less blood collection at present. Because the amount of blood collected is small, the puncture is shallow and the pain is less. The typical representative of this blood glucose meter is risperidone, which not only takes less blood, but also can take blood from other parts of the body where the pain is not obvious. Of course, the blood collection pen of Roche blood glucose meter has its unique painless patent, and the pain of blood collection is also very small. Other blood glucose meters with less blood collection can also be considered.
(3) For economic reasons, patients who want to choose a blood glucose meter with cheap test paper and relatively high accuracy can consider a domestic blood glucose meter. The test paper price of domestic blood glucose meter is incomparable with that of imported blood glucose meter. Typical representatives are Beijing Yicheng and Changsha Sannuo blood glucose meters, which are the pride of China people.
Of course, every patient has his consideration, so is there a unified reference for choosing a blood glucose meter? It is suggested that patients should master five elements when purchasing:
1. The accuracy should be as close as possible to the detection value of venous blood taken at the same time, and the difference should not be too big, otherwise there may be a tragedy that will delay the illness.
2. Looking at the service, we should know the after-sales service of the blood glucose meter and whether the test paper supply is in place to prevent the situation of "cooking without rice".
3. Look at the operation of the machine, such as whether the blood collection needle is convenient to use, how much blood is needed, the reading time of the machine, the size and clarity of the display screen, the convenience of replacing the battery, the beauty and size of the machine, etc.
4. Look at the price, not only the price of the blood glucose meter, but also the acceptable test paper price according to your own situation. If you feel that the price of test paper used is beyond your normal budget, please choose those blood glucose meters with brands and relatively cheap test paper. Because for patients who need to measure blood sugar regularly, the expenditure of test paper is also an extra burden, which needs to be comprehensively measured.
Don't buy parallel goods just because you are greedy for cheap. At present, smuggled blood glucose meters have targeted the huge consumer market in China. The price of parallel blood glucose meters is nearly half cheaper than the genuine market price. Without the Chinese manual and Chinese warranty card, the after-sales service of this product cannot be guaranteed.
Cheap buyers will buy bad meat.
