Abstract

The invention provides easy handling and low cost-support equipment for measuring optical nerve-activity which is less stressful for subjects or doctors and the like. The support equipment, which provides light stimulation for subject eyes with its main body 10 fixed to the subject-head region and measures the subject optical nerve-activity, comprises a thin walled-main body 10 with a plurality of optical fibers 11 joined in the width direction; light emission regions 13a, 13b at least one of which is positioned in the main body aligned to the subject eye-position(s) and composed of a plurality of light leak parts 11c formed in peripheral surfaces of the optical fibers 11; and a connector 12a for connecting with a light emission device 12 providing light for each of the plurality of optical fibers.

Claims

1. A support equipment for measuring optical nerve-activity used for measuring subject-optical nerve activity by providing light stimulation for the said subject eyes with a main body fixed to the said subject-head region, comprising:

the main body which is thin walled with a plurality of optical fibers joined in the width direction; and

light emission regions at least one of which is positioned in the said main body aligned to the said subject eye-position(s) and composed of a group of plural light leak parts formed in peripheral surfaces of the said optical fibers, and

a connector which is set in at least one ends of the said optical fibers for connecting with a light emission device providing light for each of the said plurality of optical fibers.

2. The support equipment for measuring optical nerve-activity as in claim 1 wherein the said optical fiber-diameter is 0.5 mm or less, the thickness of the said main body including the said optical fibers is 1 mm or less, and the said main body-weight is 50 g/m or less.

3. The support equipment for measuring optical nerve-activity as in claim 1 wherein warp threads composing a cloth in the longitudinal direction which forms the said main body are partially or all replaced with the said optical fibers.

4. The support equipment for measuring optical nerve-activity as in claim 1 wherein the said light leak parts are composed of acute angle-incisions formed in the said optical fiber-peripheral surfaces at various orientations and intervals.

5. The support equipment for measuring optical nerve-activity as in claim 1 wherein one ends of the said optical fibers are bundled, melted, and cut.

6. The support equipment for measuring optical nerve-activity as in claim 1 wherein the said light leak parts in a plurality of the optical fibers arranged in parallel in the said-single main body are formed in every other or every plurality of the optical fibers in one of the said light emission regions alternately with those in the other light emission region.

7. The support equipment for measuring optical nerve activity as in claim 1 wherein a plurality of the said main bodies are layered keeping light propagation directions in the said optical fibers same.
