1. A measuring probe comprising:
- a holder portion which is adapted to be attached to a subject; and
an optical fiber for at least one of irradiation and detection, whose distal end portion on a subject side is retained by the holder portion;
wherein the optical fiber is led out from a side surface of the holder portion and is bent inside the holder portion such that the distal end portion is directed to the subject when the holder portion is attached to the subject;
wherein an optical fiber fixing member which fixes the distal end portion of the optical fiber is arranged in the holder portion; and
wherein an optical fiber protecting member which protects the bent portion of the optical fiber is arranged inside the holder portion.

Abstract
In a measuring probe, the distal ends of an irradiation optical fiber and a detection optical fiber on the subject side are held by a holder portion which is to be mounted on a subject. The optical fibers are led out from the side surface of the holder portion. Further, the optical fibers are bent in the holder portion so that the distal ends of the optical fibers are directed towards the subject when the holder portion is mounted on the subject.

15. A living body optical measuring device comprising:
-
a measuring probe having; a plurality of optical fibers that irradiate a subject with measurement light and receive the measurement light returning from the subject, and a holder portion which is adapted to attach the measuring probe to the subject; wherein the optical fibers are led out from a side surface of the measuring probe and are bent inside the holder portion such that their distal end portions are directed towards the subject when the holder portion attaches the measuring probe to the subject; wherein an optical fiber fixing member which fixes the distal end portion of the optical fibers is arranged in the holder portion; and wherein an optical fiber protecting member which protects the bent portion of the optical fibers is arranged inside the holder portion. - View Dependent Claims (16, 17)
