At present, Mercury thermometer and electronic thermometer are mainly used for common contact measurement. Non-contact measurement refers to the use of infrared thermometer, including ear thermometer, forehead temperature gun, etc.
Body temperature can be measured by contact and non-contact. Contact measurement includes three temperature measurement methods, namely, direct measurement through oral cavity, armpit and anus. The non-contact method is to obtain the actual body temperature of a person through infrared thermometry and shell temperature.
What kinds of thermometer are divided? Let's take a look:
1. Mercury thermometer:
Mercury thermometer is no stranger to everyone, almost everyone can use it, because it is very convenient to use and very simple to measure. Mercury thermometer is also easy to clean, convenient to disinfect, and very accurate to measure.
However, the disadvantages are hard to ignore. It takes a long time to measure, usually 10 minutes; And most mercury thermometers are made of glass, which is very easy to break. Once broken, the exposed Mercury will pollute the environment, it is not good for health. Mercury thermometer measurement needs people's cooperation. Like some babies, it is inconvenient for people with uncontrollable behaviors to use.

2. Infrared thermometer:
Infrared thermometer is a measuring meter that uses the radiation principle to measure the body temperature of human body. The infrared sensor it uses only absorbs the infrared radiation of human body and does not emit any radiation to the outside world, the body temperature is sensed by a non-contact method. The infrared thermal radiation of human body is gathered on the detector, which converts the radiation power into an electrical signal, which can be displayed in the unit of temperature after being compensated for the ambient temperature.
At present, the common infrared temperature measuring instruments on the market mainly include ear thermometer and forehead temperature gun.
3. Ear thermometer:
The temperature measured is eardrum, eardrum can reflect the core body temperature of the human body, which can best reflect the real body temperature of the human body. Therefore, ear thermometer is used in many medical places instead of mercury sphygmomanometer.
However, because the meatus acusticus of a person is not straight, when measuring ear temperature for infants under 3 years old, they need to lift the auricle back and lower, and adults over 3 years old should lift the auricle above the right-out, to put ear thermometer in the right place.
Therefore, the meatus acusticus diameter of babies under 6 months old is relatively small, and it is not suitable to use ear thermometer. Suffering from ear diseases such as otitis media and otitis media, it is not suitable to use ear thermometer when the ear holes are wet after swimming and bathing. In addition, if you measure multiple times in a short period of time, the ear thermometer itself will affect the temperature of meatus acusticus and the accuracy of the measurement results.
4. Forehead temperature gun:
It mainly relies on sensors to receive infrared rays of human body to judge body temperature. In an ideal state, the measurement results should be accurate, but there are many influencing factors. Room temperature and skin dryness will affect the results, the body temperature measured directly after washing or taking off ice stick does not reflect the actual temperature of the human body.
However, forehead temperature gun wins is convenient and fast. It is often used in places such as kindergartens, airports, and railway stations where people flow heavily. In addition, it can also be used in places where fever patients are quickly screened.
