Recently, the number of people infected with the new coronavirus has started to increase, Dr. Medexpro and everyone review the use of thermometer.
What kinds of thermometer are commonly used?
Common thermometers include glass thermometers, electronic thermometers and infrared thermometers.
1. Glass thermometer, is the most common thermometer, it can make the mercury column with the temperature rise to maintain the original position, easy for users to observe at any time.
2.Electronic thermometer, using the physical parameters of some substances (such as resistance, voltage, current, etc.) and the environment temperature between the determined relationship, the body temperature in the form of numbers displayed. Electronic thermometer reading intuitive, small, portable, easy to damage, than ordinary mercury thermometer easier to keep.
3. Infrared thermometer, by measuring the radiation temperature of ear eardrum or forehead, non-contact measurement of human body temperature.
What method should I master to take my temperature?
First of all, we must understand the changes in human body temperature in general. Human body temperature varies with time, and the body temperature is lower in the early morning and slightly higher in the late afternoon. So it's normal to have a slight difference in temperature measurements over the course of the day.
Secondly, it is necessary to understand the method of temperature measurement in different parts of the body and the normal temperature range of that part. General temperature measurement is mainly divided into oral temperature measurement, axillary temperature measurement, anal temperature measurement, ear temperature measurement and frontal temperature measurement. For different parts, different thermometers are usually used for measurement.
1. To measure the mouth temperature, place the front end of the thermometer sensor under the tongue and press it slightly hard. During the measurement, the mouth should be completely closed, and do not speak during the measurement.
2. For armpit temperature measurement, the thermometer sensor head is placed in the most front of the armpit parallel to the body, and the arm is close to the body to ensure that the thermometer is completely covered by the skin and is not affected by the air. The normal axillary temperature is about 35.0 ~ 37.0.
3. For anal temperature measurement, apply a water-soluble lubricant to the front end of the thermometer, insert the front end of the thermometer less than about 1.5cm to the anal opening, and stop the measurement immediately if you encounter any resistance. The normal anal temperature is about 36.2 ~ 37.9℃.
4. For ear temperature measurement, clean earwax or foreign matter in the ear canal before measurement, gently pull the ear back to straighten the ear canal, put the detection head into the ear canal, and press the measurement key to read the value. Normal ear temperature is about 35.8℃ ~ 38℃.
5. Frontal temperature measurement, clean the sweat or cosmetics near the forehead before measurement, push the hair away with your hand, point the temperature sensing head at the distance of about 1 ~ 3cm between the brow, and press the measurement key to read the value. Normal frontal temperature 35.8 ~ 37.8℃.
Some guys can easily find that the human body temperature not only varies at different times of the day, but also the normal temperature range of different parts of the body. Generally speaking: evening temperature > morning temperature, ear temperature, anal temperature > mouth temperature > frontal temperature, axillary temperature. Therefore, when measuring body temperature, we should learn to distinguish scientifically and make reasonable judgments!
