LIVING BODY INFORMATION MEASURING APPARATUS
First Claim
Patent Images
1. A living body information measuring apparatus, comprising:
- means for irradiating light to a subject;
means for detecting light from the subject;
means for acquiring information with regard to a tissue condition of the subject based on a detecting signal of the light; and
position determining means for determining an acceptability of a position of irradiating the light based on the detecting signal of the light,wherein the position determining means determines that the irradiating position is acceptable when an amount of variation of the detecting signal of the light is lower than a threshold.

Abstract
A living body information measuring apparatus includes an optical system for irradiating light to a subject and detecting light from the subject, a signal processing portion for acquiring information with regard to a tissue condition of the subject based on a detecting signal of light, and a position determining portion for determining an acceptability of an irradiating position of light based on the detecting signal of light.

6. A living body information measuring apparatus including:
-
a light irradiating portion for irradiating light to a subject; means for detecting light diffused, transmitted or reflected in the subject; means for acquiring information with regard to a tissue condition of the subject based on a detecting signal of the light; position determining means for determining an acceptability of a position of irradiating the light based on the detecting signal of the light; a moving mechanism for moving the light irradiating portion substantially in parallel with a body surface of the subject; and control means for controlling the moving mechanism for moving the light irradiating portion when the position of irradiating the light is determined to be improper, wherein the position determining means determines that the irradiating position is acceptable when an amount of variation of the detecting signal of the light is lower than a threshold.
