I. How to sterilize the blood glucose meter before using it
After disinfecting fingers with iodophor, iodophor will remain on the skin. After the blood and iodophor are mixed, the iodine-containing substances in the iodophor will chemically react with the test strip for measuring blood sugar, which may cause the measured results The error will have a certain effect on reducing the blood sugar level.
Do not use iodophor for sterilization of blood sugar.
Because the blood glucose meter used to detect blood sugar is measured by test strips, and after disinfecting fingers with iodophor, iodophor will remain on the skin. After the blood and iodophor are mixed, the iodine in the iodophor will Substances will chemically react with the test strips used to measure blood sugar, which may cause errors in the measured results, resulting in a certain reduction in blood sugar levels.
The blood sugar measurement can be disinfected with 75% medical alcohol. After the alcohol has completely evaporated, prick your finger to measure the blood sugar, so as to prevent the blood flowing out from being diluted by the alcohol, which will make the measured results biased.
When disinfecting fingers with alcohol, first wash your hands, especially the blood collection site, with soap and dry with a clean cotton ball. Then use a clean medical cotton swab dipped in 75% medical alcohol or 75% medical alcohol cotton ball, and rotate back and forth around the point where the needle is to be punctured for blood collection, and the blood sugar can be measured after the alcohol is released.
2. Instructions for daily maintenance of blood glucose meter
1 , keep it clean
During the use of the blood glucose meter, it is often polluted by dust, fibers, sundries, etc. in the environment, especially if it is accidentally polluted by blood during the test, which will affect the test results. Therefore, the blood glucose meter should be placed in a storage bag after each use and cleaned regularly. Care should be taken when cleaning the test area. Do not use alcohol or other organic solvents when wiping, so as not to damage the instrument. Use a slightly soaked cotton swab or soft cloth wipe. In addition, it is best to disinfect the outside of the fuselage daily, using a cotton swab or soft cloth soaked in disinfectant.
2, stored correctly
Blood glucose meters without batteries can generally be stored in an environment of -25 to +70°C Generally, blood glucose meters with batteries can be stored in an environment of -10 to +50 °C, and the relative humidity of the environment should generally not exceed 90%. The storage conditions of different blood glucose meters are slightly different. You can read the manual carefully. It also needs to be emphasized that the above mentioned is the storage environment of the blood glucose meter, and the environmental conditions (temperature, humidity) required to detect blood sugar will be more severe, and there will be clear labels on the manual. In addition, the blood glucose meter should avoid being stored in electromagnetic fields (such as mobile phones, microwave ovens and other accessories) for a long time, and at the same time avoid collisions and violent shocks.
3, regular proofreading
Except for each time a new box of test strips needs to be adjusted (no code adjustment required) Except for blood glucose meter), you also need to calibrate the blood glucose meter regularly. Generally, the accuracy of the blood glucose meter will drop significantly after 2000 tests, so it should be calibrated. Proofreading should be carried out immediately in the following situations: suspecting that there is a problem with the instrument, the test results are inconsistent with your own feelings (for example, you feel that you have low blood sugar, but the test results are high), or the blood glucose meter is dropped.
4, replace the battery in time
The manual of the blood glucose meter will indicate that when there is a symbol on the screen, it will indicate that the battery is low. Although about fifty tests can still be performed after the low power symbol appears, it is best to replace the battery with a new one as soon as possible to avoid damage to the instrument and affect the test results.
5, store the test strip correctly
In clinical practice, the blood glucose meter itself is less likely to malfunction, while the test strip is less likely to fail. More susceptible to temperature, humidity, chemicals, etc. The test strip should be stored in the original bottle, and stored in a dry, cool and dark environment. Close the cap immediately after taking out the test strip, and avoid touching the test area with your fingers when taking the test strip. Single-packed test strips can be stored until the expiration date on the box, while bottled test strips should be used within one month after opening.
