Thermometer is necessary for family to prevent cold and fever. People are usually busy with their work and under great pressure. Once the weather changes, a cold and fever are inevitable. At this time, we need to use a thermometer to measure the temperature. How to use a thermometer? Let's get to know.

How to use the thermometer

1. disinfection

Before using the mercury thermometer, the surface of the thermometer needs to be disinfected with alcohol cotton to ensure that there is no bacterial cross infection, which is safer.

2. measurement of axillary fossa

A common method is to measure the armpit. We first shake the degree of the mercury thermometer below 35 , and then put the mercury end of the thermometer on the top of the armpit and clamp it. Make sure the thermometer is in close contact with the skin, and take out the thermometer almost 5 minutes later. After reading the degree, wipe it with the paper drawing for next use.

3. oral measurement

When measuring the oral cavity, first shake the degree of mercury thermometer below 35 , put the thermometer under the tongue and press it slightly. Before that, you must remember to disinfect and wipe the surface of the thermometer before putting it into the mouth. The time is three minutes. Remember not to talk in the middle.

After the oral temperature measurement is completed, wipe the whole mercury thermometer with an alcohol cotton ball and put it back in place for the next time.

4. anal measurement

The method of anal measurement is generally used for comatose patients or children. The patient lies on his back. After lubricating the head of the anal surface with oil, insert it into the anus slowly until it reaches 1 / 2 of the anal surface, and read it after 3 minutes.

What about mercury thermometer

Hold the tail of the mercury thermometer in one hand, that is, the end far away from the mercury column, keep the eye at the same level with the thermometer, and then slowly rotate the thermometer. When you see the thick mercury column (the red line in the middle) from the front, you can read the corresponding temperature value. When reading, please do not touch the mercury end of the thermometer by hand, which will affect the mercury column and cause inaccurate measurement.

Above for you to introduce the correct use of thermometer, but also for you to see the mercury thermometer method, hope to help you.
