SHEET-LIKE HEMOSTATIC MATERIAL EMPLOYING POLY-Y-GLUTAMIC ACID, AND METHOD OF MANUFACTURING SAME

摘要

A sheet-like hemostatic material (10A to 10E) is provided with: an adhesive layer (11) which serves as an affixing surface to a bleeding site and which is formed from at least poly-γ-glutamic acid (y-PGA); and a covering layer (12) which is a sheet formed from at least one biodegradable material (covering material) other than γ-PGA, and which serves as an opposite surface to the affixing surface. At least one of the adhesive layer (11) and the covering layer (12) is a single sheet. If the adhesive layer (11) is a single sheet, the adhesive layer (11) should be a sponge-like sheet, and if the adhesive layer (11) is a partial layer, the adhesive layer (11) should be a sponge-like sheet or a nonporous layer. Alternatively, in another sheet-like hemostatic material, a sheet which is formed from at least poly-γ-glutamic acid (γ-PGA) and to which at least one of a saccharide and collagen has been added is provided as the adhesive layer.
