How to choose and use many kinds of thermometers

In daily life, the first symptom of many diseases is fever, and it is necessary to use a thermometer to determine whether a fever is present. Therefore, the thermometer is a necessary tool in the family medicine cabinet, so how to choose the thermometer when buying it?

NON-CONTACT FOREHEAD INFRARED THERMOMETER

It measures body temperature by absorbing infrared radiation energy emitted by the human body. Because it belongs to a non-contact thermometer, it can avoid cross infection, and is suitable for use in public places, where there is a large flow of people, and where fever patients need to be quickly screened.

EAR THERMOMETER

It measures the temperature of the eardrum, which better reflects the true body temperature of the human body. In addition, if the measurement is repeated several times in a short period of time, the ear temperature gun itself will affect the temperature of the ear canal, which will also affect the accuracy of the measurement results.

DIGTAL THERMOMETER

Electronic thermometers are used in much the same way as classical mercury thermometers, which are placed under the tongue, under the arm or in the rectum to measure 

body temperature. The downside, however, is that it takes longer to measure body temperature compared to the first two devices, ranging from 30 seconds to more than 3

minutes depending on the brand. In addition, diet (cold drinks, hot drinks), strenuous exercise, bathing, etc., will affect the measurement results, and you need to wait 30 

minutes before measuring your temperature.

Finally, the most important point needs to be reminded that body temperature is only a reference, whether you need to take drugs, when to use drugs, according to the symptoms and test results to judge.
