The outbreak of coronary pneumonia has made people pay more and more attention to public safety. Body temperature is one of the important indicators to characterize the health of the human body. Accurate measurement of body temperature can quickly isolate suspected disease populations and avoid large-scale outbreaks of immune status. In the epidemic prevention and control work, the most widely used are infrared forehead thermometers and infrared screening instruments, but many people are not allowed to measure temperature after using infrared thermometers.
For the temperature measurement accuracy issues that people are most concerned about, how accurate is the infrared thermometer that is qualified as a medical-grade infrared thermometer and can it be used as medical diagnostic data?
Classification of thermometers: contact and non-contact thermometers
Common human body temperature measurement methods are mainly divided into two categories, namely contact and non-contact.
Common contact measurement methods include mercury thermometers, household electronic thermometers, and medical temperature probes, which measure the temperature of the human body through contact with relevant parts of the human body, such as underarms and oral cavity. High, can meet the requirements of rapid and accurate body temperature measurement in clinical diagnosis.
However, since contact measurement requires direct contact with the human body, each measurement may be infected by germs, requires frequent disinfection, and the measurement speed is slow, and continuous and rapid measurements cannot be performed on a large number of human bodies. For example, mercury thermometers need to be placed under the arm for 15 minutes, while home electronic thermometers and medical temperature probes also need 3 to 5 minutes to measure.
