Title:
LIVING BODY INTERNAL TEMPERATURE MEASURING DEVICE AND LIVING BODY INTERNAL TEMPERATURE MEASURING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/230370
Kind Code:
A1
Abstract:
Time-series data of a core temperature of a living body are acquired using a heat flux sensor (20) including two temperature sensors (20u, 20s), while a blood flow rate in the vicinity of the heat flux sensor (20) is measured by means of a blood flow sensor (30). A calculating circuit (40) calculates a delay time until a variation in the core temperature of the living body is reflected in the skin temperature thereof, on the basis of the blood flow rate measured by the blood flow sensor (30) and a relationship between the blood flow rate and the delay time until a variation in the core temperature of the living body is reflected in the skin temperature thereof, prepared in advance, and corrects a time associated with the core temperature of the living body on the basis of the delay time. In this way, variations in the core temperature can be understood more accurately.
