EXTERNAL USE LESION PROTECTIVE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide an external use lesion protective material which is capable of efficiently inactivating an objective hazardous material by a photocatalyst reaction without exerting a serious damage occurring in the photocatalyst reaction to the tissue and cells of a lesion. SOLUTION: The external use lesion protective material (20) is provided with a sheet (21) which is worn at the lesion and a photocatalyst (26) held in a light receivable state at this sheet, and this sheet is provided with a porous layer (25) having gaps of sizes to accept the exudate from the lesion and the foreign matter mingled in the exudate. More preferably, one or >=2 kinds of captive materials (28) having selective bondability to one or >=2 kinds of the materials which can be inactivated by the photocatalyst reaction are arranged in a position proximate to the photocatalyst.
