Body temperature measuring method and device

Abstract

The invention discloses a body temperature measuring method and device. According to the method, an actual temperature rise curve detected by a temperature probe is regarded as a result of fitting a first ideal temperature rise curve and a second ideal temperature rise curve. By means of the four equitime interval points on the actual temperature rise curve and actual temperature corresponding to each equitime interval point, first ideal temperature, corresponding to each equitime interval point, on the first ideal temperature rise curve and second ideal temperature, corresponding to each equitime interval point, on the second ideal temperature rise curve are calculated; then, the body temperature is predicted on the basis of the first ideal temperature rise curve or the second ideal temperature rise curve to obtain the body temperature. Compared with the prior art, the method adopts the ideal temperature rise curves for predicting the human body temperature, meets the requirement of a Newton heat conduction formula, and improves the prediction accuracy.

Description

Technical field [0001] This application relates to the field of body temperature measurement, and more specifically, to a body temperature measurement method and device. Background technique [0002] There are two types of electronic thermometers: continuous and predictive: the continuous electronic thermometer can display the temperature of the measured part in real time and continuously. The predictive electronic thermometer can display the temperature of the measured part relatively quickly and discontinuously. Its measuring principle is: after the temperature probe contacts the human body, the change characteristics of the heating curve within a period of time are used to predict the temperature probe and the measured part of the human body The stable temperature when thermal equilibrium is reached. Because it does not need to wait until the temperature probe and the human body reach thermal equilibrium to obtain the human body temperature, the time required for measurement ...

Problems solved by technology

Newton's heat transfer formula is established under the ideal condition that there is an endless, well-stirred heat source used to heat the sensor. However, the temperature rise curve obtained in practical applications is not the ideal temperature rise curve required by Newton's heat transfer formula. Therefore, the existing prediction Low predictive accuracy of traditional electronic thermometers
