Liquid dressing for surgical department

Abstract

A surgical liquid dressing is a monolayer film prepared by mixing glue liquid comprising the following formulated ingredients: polyvinyl alcohol aqueous solution for 100 shares by wt, acrylic ester emulsion pressure-sensitive adhesive for 4-8 shares by wt, and glycerol for 1 share by wt; another surgical liquid dressing is a bilaminar film prepared by following two layers of solution, the lower layer is polyvinyl alcohol aqueous solution, and the upper layer is polyamide alcoholic solution soluble in alcohol; and another surgical liquid dressing is a multi-laminar film prepared by following three layers of solution: the lower layer is polyvinyl alcohol aqueous solution, the middle layer is polyvinyl acetate solution soluble in alcohol, and the upper layer is polyamides alcoholic solution. A plurality of film forming materials with enough strength, water resistance and bioavailability are produced by multiple composition of one or several polymers and proper additives, and can be coated on body surface of organism, such as human hands, limbs, bellies, and etc, to acting with isolation and protection function for certain time. Said materials can be used in the medical occasion or the personal hygiene protection occasion, such as used as surgical dressing, temporary protective gloves, and etc.
