Human body temperature is an important technical indicator for epidemic prevention and control, fever screening and other work. At present, all public places are equipped with necessary temperature measurement equipment, but if the temperature is not accurately measured, it will not only fail to play its due role, but will cause confusion and panic. When it comes to body temperature, we first introduce two concepts. Human body temperature is divided into internal body temperature and body surface temperature. The body temperature we generally refer to refers to the body temperature, which is closer to the body temperature is the oral, rectal or armpit temperature. Body surface temperature refers to the temperature of the skin on the surface of the human body, such as the temperature of the forehead and wrist surface.
Thermometers used for body temperature measurement can be divided into two categories: contact thermometers and non-contact thermometers. Contact thermometers include commonly used glass thermometers and medical electronic thermometers, which are generally placed in the armpit, mouth or rectum. After 5-10 minutes of heat conduction time, the body temperature can be measured. The accuracy of this thermometer is relatively high, generally 0.1℃-0.2℃.
Non-contact thermometers include infrared forehead thermometers, infrared screening instruments, infrared ear thermometers, etc. The infrared forehead thermometer is the temperature measuring gun that the inspectors hold when entering the community. Infrared screening equipment is a relatively large thermometer with infrared cameras and large screens that everyone sees in large public places such as stations and airports. There is also a less commonly used infrared ear thermometer. The measurement principle of these three non-contact thermometers is the same, that is, the principle of infrared rays is used to measure the body surface temperature of the human body and convert it into the body temperature to determine whether the human body has a fever. The accuracy of this kind of thermometer is lower, generally 0.3℃-0.4℃.
Measuring with a glass thermometer is the most accurate, but it is slow and inconvenient to use. Infrared forehead thermometers are convenient and fast to measure, but have low accuracy. We generally say that over 37.3 ℃ is a fever, which refers to the body temperature of the armpit. The forehead thermometer can only be judged by converting it into the temperature of the armpit. Combining the advantages of the two thermometers, it is generally recommended to use an infrared forehead thermometer for preliminary screening and a glass thermometer for accurate judgment.
(1) Pay attention to the working environment. Infrared forehead thermometers are generally required to be used at a temperature of 16°C-35°C, generally around 20°C. It is currently winter, the outdoors is relatively cold, and the monitoring points for epidemic prevention and control are generally located outdoors. If the infrared forehead thermometer works in an outdoor low temperature environment for a long time, the obtained values are prone to deviation. Therefore, it is recommended to use it in an indoor windless environment as much as possible. If you can't do it, it is also recommended to do some temperature protection for the infrared forehead thermometer, such as putting it in a cotton coat or sticking a warm baby that is not too hot.
(2) Pay attention to the measurement mode. Some infrared forehead thermometers have two modes: material temperature mode and body temperature mode, so make sure to set it in body temperature mode for measurement. Generally, the boot is in body temperature mode, and if it is messed up, it can be restarted.
(3) Pay attention to the measurement site. In a windless indoor environment, it is recommended to measure the position of the center of the forehead, which is the brightest part of the forehead that we generally see. The distance is generally 1-3 cm according to the requirements of the manual. Also make sure that it is not blocked by hair, sweat, hats, etc. When repeating the measurement, first remove the infrared forehead thermometer probe, and then perform the next measurement after an interval of 5 seconds. If the measurement method is incorrect, such as close to the forehead, it will be inaccurate. At present, many prevention and control monitoring points do not have indoor temperature measurement conditions. What should I do if there is wind outside the low temperature? At this time, you can use warmer parts such as the wrist and neck instead.
