A home-use blood glucose detector, referred to as a blood glucose meter, is easy to carry, simple to operate, and can detect blood glucose levels more accurately. Since most of the users are elderly patients or non-professional testing medical staff at the grassroots level, they lack professional and standardized guidance, so the test results often have a certain gap with the actual blood sugar level, thus delaying the diagnosis of the disease. Share some precautions when using blood glucose meters with diabetes patients and primary care doctors.
1. When using it at home, you should avoid placing the blood glucose meter in environments with high temperature and high humidity such as the kitchen or bathroom. You should also not place the blood glucose meter, especially the test strips, in a refrigerator or freezer. It should be opened before use in winter. Use air conditioners to adjust the room temperature to 15-25°C and pre-warm it in advance.
2. Every time the battery is replaced, the parameters are reset, or the blood glucose meter may be damaged, the test piece must be re-inserted to test the performance of the blood glucose meter.
3. Before using the new batch of test strips, you must insert the password card and re-enter the calibration password. Only the code on the password card, the password number displayed on the blood glucose meter screen and the password code marked on the test strip bottle are consistent. , can be detected. If there is a difference, the measurement results will be incorrect or the operation will be inoperable.
4. Test pieces that have expired, have damaged electrode areas, or contaminated reaction areas cannot be used. It cannot be used if the shelf life exceeds 3 months after opening. It is strictly forbidden to mix test strips from different manufacturers or different batch numbers of the same manufacturer, otherwise it will cause wrong results or make the operation inoperable.
5. The pen cap of the blood collection pen is most susceptible to contamination. It is usually soaked in 84 diluent or a disinfectant solution of 1 part bleaching powder and 10 parts water for 30 minutes for disinfection. Do not soak the entire pen. Wipe and disinfect the entire pen with 75% alcohol. If possible, use it exclusively for your own use.
6. Precautions during blood collection: Use 75% alcohol for disinfection of blood collection, and iodophor disinfection is prohibited. The depth of blood collection can be adjusted through the 1-5 gears on the blood collection pen. Squeeze gently to bleed, and it is strictly forbidden to squeeze to bleed. Sufficient blood should be sucked to fill the reaction area. Excessive squeezing and bleeding and insufficient blood sucking will lead to erroneous results.
When using a blood glucose meter for daily blood glucose level monitoring, when the test results are inconsistent with the patient's subjective symptoms or are significantly different from the expected value of daily testing, comprehensive considerations should be made based on daily life, diet, medication, etc. After eliminating the above reasons, the blood glucose meter should be re-checked, re-calibrated and re-tested, and the superior professional physician and instrument dealer should be contacted promptly to help solve the problem. If possible, it is recommended to go to the hospital to test the blood glucose value. Never make any personal changes to the treatment plan or dosage.
