Assignee: NIPPON TELEGRAPH AND TELEPHONE CORPORATION
Field: Measurement (Instruments)
Classification: CPC G  A | IPC A  G

Claim 7:
8. An internal body temperature measurement method comprising:
measuring, by a temperature sensor, an epidermis temperature of a living body;
measuring, by a heat flux sensor, a magnitude of a heat flux discharged from a body surface of the living body;
measuring, by a blood flow sensor, a blood flow rate of the living body; and
calculating a core temperature of the living body from the epidermis temperature and the magnitude of the heat flux;
calculating a delay time corresponding to the epidermis temperature measured by the temperature sensor by correlating the blood flow rate measured by the blood flow sensor and a relation between a plurality of different blood flow rates and a parameter, the parameter defining a respective delay time until a fluctuation of the core temperature of the living body is reflected on the epidermis temperature of the living body with each of the plurality of different blood flow rates; and
correcting a time corresponding to the core temperature of the living body based on the delay time, wherein correcting the time corresponding to the core temperature of the living body based on the delay time comprises correcting the time corresponding to the core temperature of the living body based on the delay time that is less than a predetermined threshold.
