BIOSIGNAL MEASURING PROBE

摘要

PROBLEM TO BE SOLVED: To precisely interpose a matching medium between a probe and an organism.

SOLUTION: This probe 1 is used for a biosignal measuring device which emits near infrared rays toward the surface of the organism, receives the reflected light from inside the organism and measures the concentration of the components in the organism based on a biosignal obtained from the components of the received light. This probe is provided with a near infrared ray emission part 12; a received light incident part 14; and a delivery means 2 comprising a storage part 20 which stores the medium 3 for matching the refractive index to be interposed in an interface with the organism, and a transport means 22 which delivers the medium for matching the refractive index inside the storage part from an outlet by applying pressure. The probe 1 itself is provided with the medium 3 for matching the refractive index and interposes the medium 3 between itself and the organism by the delivery of the medium 3.
