Probe device

摘要

A biophotometrical probe device provided with a probe unit designed to keep a vertical posture of the probe unit when attached to an examinee's head and easy to sweep aside hair while keeping this vertical posture is provided. The probe device comprises a plurality of light irradiation probe units (300) provided with light irradiation means at a tip thereof, a plurality of light detection probe units (400) provided with light detection means at a tip thereof, and a probe support unit (200) which holds a grid-shaped array of the mutually neighboring light irradiation probe units (300) and light detection probe units (400). The light detection probe unit (400) is provided with a main projection (412) formed so as to protrude on the surface side of the living body and a plurality of sub projections (414) arranged around the main projection (412), the main projection (412) is provided with light communication means (413) on an axial core thereof and the sub projections (414) are supported on the probe support unit (200) in a manner pivotable around the axial core of the light communication means (413).
