Blood glucose meter, also known as blood glucose meter, is an instrument used to monitor blood glucose. The test paper used is called blood glucose test paper. After disinfecting the fingertip, prick the fingertip with a needle, and drop the blood on the test paper of the blood glucose meter. Through the reaction between blood and chemical substances of the blood glucose test paper, the blood glucose is monitored by the blood glucose meter.
Blood glucose meter, also known as blood glucose meter, is an electronic instrument for measuring blood glucose level. The blood glucose meter can be divided into photoelectric type and electrode type. The test principle of electrode type blood glucose meter is more scientific, and the electrode can be embedded.
Blood glucose meter is an instrument used to monitor blood glucose. The test paper used is called blood glucose test paper. After disinfecting the fingertip, prick the fingertip with a needle, and drop the blood on the test paper of the blood glucose meter. Through the reaction between blood and chemical substances of the blood glucose test paper, the blood glucose is monitored by the blood glucose meter. The measured blood glucose is called capillary fingertip blood. This result is relatively accurate, but it is still a little different from venous blood. Generally speaking, the measured results are very reliable for patients with diabetes.
但是在使用血糖仪的时候需要注意，需要定期的校正。再有就是当发现自己监测状态的血糖，无论是空腹血糖、餐后血糖出现问题的时候，需要到医生那里去需要做静脉血来进一步的验证。血糖仪可能有国产的品牌或者是进口的品牌，一般希望选择的是质量比较可靠的，售后服务比较好一点的。特别是价钱上不要买得过贵，比如 400-500 块钱的血糖仪就已经非常的优秀了，在使用过程当中可能会遇一些困难，比如刚得到的血糖仪操作的过程当中可能不够熟练或者担心怕疼，但是尽量在医生的指导下，自己尽可能地多练习，使血糖仪更好的为糖尿病患者再来一个很好的血糖监测，来记住平常日子病情的变化，正好的和医生沟通，有助于医生对患者的病情评估和治疗方案的调整。
But in the use of blood glucose meter need to pay attention to the need for regular correction. Another is that when you find that you are monitoring the state of blood glucose, whether it is fasting blood glucose, postprandial blood glucose problems, you need to go to the doctor, need to do venous blood to further verify. Blood glucose meter may have domestic brand or imported brand, generally hope to choose the more reliable quality, better after-sales service. In particular, the price should not be too expensive, such as 400-500 Yuan blood glucose meter has been very excellent, in the use of the process may encounter some difficulties, such as just got the blood glucose meter operation process may not be proficient or afraid of pain, but as far as possible under the guidance of the doctor, practice as much as possible, so that the blood glucose meter better for diabetic patients to have a good blood glucose monitoring, to remember the normal days of illness It is helpful for the doctor to evaluate the patient’s condition and adjust the treatment plan.
Working principle of blood glucose meter
血糖仪从工作原理上有两种分别，一是光电型，一是电极型。光电血糖仪类似 CD 机，有一个光电头，它的优点是价格比较便宜，缺点是探测头暴露在空气里，很容易受到污染，影响测试结果，误差范围在正负 0.8 左右，使用寿命比较短，一般在两年之内是比较准确的，两年后建议正在使用光电型机器的患者到维修站做一次校准。。一般医院有医院代表定期进行保养，而家用血糖仪则要到售后服务部进行光头保养。
There are two working principles of blood glucose meter, one is photoelectric type, the other is electrode type. The photoelectric blood glucose meter is similar to a CD player. It has a photoelectric head. Its advantage is that the price is relatively cheap. Its disadvantage is that the detector head 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 About, the service life is relatively short, generally within two years is more accurate, two years later, it is recommended that the patients who are using the photoelectric machine to the maintenance station to do a calibration.. General hospitals have hospital representatives for regular maintenance, while household blood glucose meters need to go to the after-sales service department for bald maintenance.
电极型的测试原理更科学，电极口内藏，可以避免污染，误差范围一般在正负 0.5 左右。精度高，正常使用的情况下，不需要校准，寿命长。
The test principle of electrode type is more scientific, the electrode mouth is hidden, which can avoid pollution, and the error range is generally around plus or minus 0.5. High precision, no need of calibration and long service life under normal use.
There are two ways of blood collection for blood glucose meter, one is smearing blood, the other is sucking blood. The machine of wiping blood generally takes a large amount of blood, and the patients are more painful. If the blood collection is too much, the test results will be affected. If the blood volume is insufficient, the operation will fail and the test paper will be wasted. This kind of blood glucose meter is mostly photoelectric. Blood type blood glucose meter, test paper to control the blood sample measurement, not because of the problem of blood volume results deviation, easy to operate, with the test paper point blood drop can be.
Now most of the blood glucose meters are broken, that is, they need to take blood. For patients who need to measure blood glucose for many times, there are broken blood glucose meters, but the price is very high! In order to reduce the pain of patients’ fingertip blood collection, now we launch two blood glucose meters for arm blood collection.
Operation method of blood glucose meter
The operation of blood glucose meter is basically divided into five steps
The first step: turn on the power, part of it is to press the power switch directly, part of it is to insert the test paper directly and start it automatically.
The second step: coding adjustment. There are three ways to regulate the coding of blood glucose meter
1. Manually input the calibration code of the test paper, such as rosuvan blood glucose meter and Johnson & Johnson blood glucose meter;
2. Insert the cipher chip into the machine to automatically record the correction code of the test paper, such as Roche vitality blood glucose meter and Einstein blood glucose meter.
⒊免调码，无需手动或插入芯片，仪器自动识别 如拜耳拜安捷 2、艾科乐舒型血糖仪。
3. No code adjustment, no manual or chip insertion, automatic identification of the instrument, such as Bayer Agilent 2, ecoleshu blood glucose meter.
Step 3: blood collection and blood sucking: blood collection can be done directly with the blood collection pen equipped with the blood glucose meter, and then the blood drops are put into the test paper. Most of the test paper is siphonic, and they will be directly sucked into the blood sucking area of the test paper.
第四步:显示结果:吸血之后，就会呈现倒计时，显示测试结果。从五秒到 30 秒不等。
Step 4: display results: after blood sucking, the countdown will be displayed to display the test results. From five seconds to 30 seconds.
Step 5: complete the test and shut down. Mainstream blood glucose meters pull out the test paper automatically shut down, some early products also need to turn off the power button. Power off can reduce battery consumption and machine loss.
How to maintain the blood glucose meter
1. When the blood glucose meter and blood glucose meter test strip are not in use, please put them into the blood glucose meter bag for storage or carrying.
2. If there are foreign matters on the surface of the blood glucose meter, do not clean it with highly corrosive alcohol, gasoline, etc.; use neutral cleaning agent to wipe it. Such as cotton wet (not wet) water or alcohol wipe.
3. Do not allow any liquid to enter the tester and do not use a hair dryer to blow the tester.
4. Do not clean the slot of the strip arbitrarily.
5. If the instrument is not working properly or damaged, please stop using it and do not disassemble it by yourself.
6. Use the tester carefully. Heavy pressure or great vibration may damage the internal electronic performance of the tester.
7. Do not clean the strip slot arbitrarily.
8. Please do not store it in an environment that is too wet, too hot or too cold. The storage of blood glucose meter should avoid dust, the temperature should not be too high, and the humidity should not be too high. Violent oscillation and collision should be prevented.
