HEAT FLOW MEASURING APPARATUS AND METABOLISM MEASURING APPARATUS
First Claim
1. A heat flow measuring apparatus comprising:
- a first heat diffusing member;
a first temperature sensor that is thermally connected to the first heat diffusing member;
a second heat diffusing member;
a second temperature sensor that is thermally connected to the second heat diffusing member; and
a heat transfer layer that is disposed between the first heat diffusing member and the second heat diffusing member.

Abstract
A ring type heat flow measuring apparatus has a heat receiving section that comes into contact with a measurement target and receives heat and releases heat through transferring from a first heat diffusing member, a heat transfer layer, a second heat diffusing member, and a heat releasing section in this order. A first temperature sensor measures a temperature of the first heat diffusing member, a second temperature sensor measures a temperature of the second heat diffusing member, and heat flow is calculated using these temperatures. Heat diffusing effects of the first heat diffusing member and the second heat diffusing member enable highly accurate temperature measurement to be stably performed regardless of relative positions between an arterial blood vessel as a heat source and the first temperature sensor and the second temperature sensor.
