Title:
METABOLIC QUANTITY MEASURING DEVICE
Document Type and Number:
Japanese Patent JP2007105323
Kind Code:
A
Abstract:

To provide a method and a device for measuring metabolic quantity based on biological parameters which can be simply measured by a user.

Metabolic quantity is simply determined using a metabolic quantity formula 6 based on environmental temperature, and the biological parameters such as body temperature, blood circulation quantity, blood level of oxygen saturation, etc., measured without sampling blood, under consideration of body heat balance. The formula 6 is: (metabolic quantity (produced heat) for a whole body)=α(Ta-Tc)+β(TFS-TR). Ta is blood temperature Ta in an artery, Tc is body temperature, α is heat capacity effective value, TFS is finger skin temperature, TR is room temperature, and β is convection heat transmission ratio effective value.
