Abstract:
1. A cerebral-ischemia supervisory monitor, comprising: a pair of optical fibers which each have a tip part that is capable of being placed toward an exterior surface of a cerebrum; an irradiation portion which is connected to a basic end part of one of the optical fibers, and via this optical fiber, irradiates the exterior surface of a cerebrum with ultraviolet rays; a light-receiving portion which is connected to the basic end part of the other one of the optical fibers, and via this optical fiber, receives fluorescence that is emitted when ultraviolet rays excite cerebral cells; a control portion which controls the irradiation and irradiation stop of ultraviolet rays by the irradiation portion, and calculates an intensity of the fluorescence received by the light-receiving portion; and a display portion which displays the intensity of the fluorescence calculated by the control portion, wherein: each optical fiber is disposed inside of a belt-shaped member which undergoes plastic deformation, in parallel in a width direction thereof and along a length direction thereof; and the belt-shaped member includes a main portion for passing through an opening portion that is formed in cranial bones and searches along an interior surface of the cranial bones, and a bent-tip portion which is bent substantially perpendicularly in a thickness direction of the main portion.
