How to use thermometer correctly

1, before use, be sure to check whether the thermometer is damaged. The damaged thermometer cannot be used. When throwing a thermometer, be sure to avoid hard objects to avoid breaking the thermometer;

2. Pay attention to the timing of measurement. After eating, drinking and sweating, the body temperature will change, so avoid these times. If there are these situations, it is best to rest for half an hour before measuring. If it is for the baby, it is necessary to avoid the baby crying, so as to avoid inaccurate measurement results;

3. After the inspection, take a look at the mercury column on the thermometer, that is, whether the current temperature is below 35 degrees, then put it under your arm, clamp it, sit still for 5 minutes and take it out.

4. After taking out the thermometer, don't shake it or touch the metal head of the thermometer with your hands. Turn the thermometer gently and you can see a mercury column. The line number is the measured body temperature;

5. After using the thermometer, it is best to wipe it with alcohol. On the one hand, it can be disinfected. On the other hand, alcohol is volatile, which will cause the mercury column to drop. Then, be sure to put it where children can't get it.

Extended answer:

Human thermometer, referred to as thermometer, is a tool for measuring human and animal body temperature.

The body temperature of normal people remains relatively constant, and its normal fluctuation range is: oral temperature is 36-37℃, rectal temperature is 0.3-0.5℃ higher than oral temperature, and axillary temperature is 0.3-0.5℃ lower than oral temperature. It can record the highest temperature measured by this thermometer. After use, the thermometer should be "put back on the table", that is, the upper part of the thermometer should be forcibly dropped, so that the mercury that has risen to the tube can return to the vacuole. Other thermometers must not shake, which is a major difference between thermometers and other liquid thermometers.
