PURPOSE: To prevent pollution caused from bacteria and dryness of surface by dipping a hydrogel material of a hydrophilic polymer into an aqueous electrolytic solution and making the material absorb water of a specified ratio. CONSTITUTION: The film for surgery operation 10 composed of a hydrogel material of a transparent and flexible hydrophilic polymer. The hydrogel material of the hydrophilic polymer includes at least 80 weight percent water absorbed when dipped in an aqueous electrolytic solution, has suitable property to cover a surface to be protected and becomes a concentric shape and prevent the exposure of the surface to air, the pollution by bacteria and further the dryness of the surface. |
