BIOINFORMATION MEASUREMENT DEVICE
First Claim
1. A bioinformation measurement device for measuring bioinformation based on an intensity of infrared light, the bioinformation measurement device comprising:
- an insertion portion to be inserted in an ear cavity;
a first light inlet and a second light inlet provided at said insertion portion, for introducing infrared light irradiated from said ear cavity into said insertion portion;
an optical guide path provided in said insertion portion, for guiding first infrared light introduced from said first light inlet and second infrared light introduced from said second light inlet;
a dispersive element for dispersing said first infrared light and said second infrared light guided by said optical guide path; and
an infrared ray detector for detecting said first infrared light and said second infrared light dispersed by said dispersive element.

Abstract
A bioinformation measurement device that enables further accurate bioinformation measurement is provided. The device includes an insertion portion 104 to be inserted in an ear cavity 200; a first light inlet 105 and a second light inlet 106 provided at the insertion portion 104, for introducing the infrared light irradiated from the ear cavity 200 to the insertion portion 104; an optical guide path provided in the insertion portion 104 for guiding the first infrared light introduced from the first light inlet 105 and the second infrared light introduced from the second light inlet 106; a dispersive element for dispersing the first infrared light and the second infrared light guided by the optical guide path; an infrared ray detector 108 for detecting the first infrared light and the second infrared light dispersed by the dispersive element; and a computing unit for computing bioinformation based on the intensities of the first infrared light and the second infrared light detected by the infrared ray detector 108.
