Title:
TEMPERATURE ESTIMATION METHOD, TEMPERATURE ESTIMATION PROGRAM, AND TEMPERATURE ESTIMATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/113331
Kind Code:
A1
Abstract:
This temperature estimation device comprises: a normalized temperature calculation unit (9) for calculating temperatures by normalizing instantaneous values of the temperature of the surface of an organism (100), which have been measured by a temperature sensor (4) after a heat-resistant material (5) and the temperature sensor (4) have touched the organism (100), using the temperature of the heat-resistant material (5) before touching the organism and a set value for the temperature of the surface of the organism (100) after the touching; a temperature wave arrival time derivation unit (10) for deriving a temperature wave arrival time on the basis of the normalized temperatures; a proportionality coefficient derivation unit (11) for deriving a proportionality coefficient on the basis of the temperature wave arrival time; and a temperature calculation unit (12) for calculating the core body temperature of the organism (100) on the basis of the measurement results of temperature sensors (1, 2) provided on both surfaces of a heat-resistant material (3) and the proportionality coefficient.
