Method for estimating body nucleus temperature from forehead temperature and application thereof

Abstract

The invention belongs to the technical field of body temperature measurement, and particularly discloses a method for estimating body nucleus temperature from a forehead temperature and application thereof. Based on a pennes biological heat transfer model, a human forehead intracranial skull skin and soft tissue air finite element heat transfer model is established, the corresponding relation between the environment temperature and the forehead temperature is analyzed through a finite element analysis method, and meanwhile the influence of a human body temperature adjusting system on the skinand soft tissue blood flow and temperature is considered; a calculation model of the body nucleus temperature is established, and the forehead temperature can be converted into the body nucleus temperature at different environment temperatures by adopting the calculation model. The defect that a traditional forehead measuring method cannot accurately reflect the body nucleus temperature is overcome, the body nucleus temperature can be estimated through the forehead temperature in high-temperature and low-temperature environments, and the forehead measuring method has important significance incalculating the body nucleus temperature through the forehead temperature and non-contact infrared temperature measurement in epidemic prevention and control.

Description

technical field [0001] The invention relates to the technical field of body temperature measurement, in particular to a method for estimating body core temperature from forehead temperature and its application. Background technique [0002] Body temperature is a necessary condition for metabolism and normal life activities, and is one of the important indicators reflecting the health status of the human body. Human beings are endothermic animals, which can maintain a relatively stable body temperature in the case of environmental temperature changes. The body temperature range of healthy adults is 36.2°C-37.5°C, and the normal average body temperature is 37°C. Some human diseases are closely related to body temperature, so body temperature is one of the important basis for clinical diagnosis and prediction of certain diseases. The structure of the human body is relatively complex and the structure of each part is quite different. The temperature of the peripheral tissue of ...
