SYNTHETIC WOUND COVERING

摘要

A synthetic hydrophilic membrane is prepared by graft polymerization of hydrophilic monomers with a polyurethane substrate. The resulting material has a water permeability in the range from about 1,000 to 8,000 g/m2/24hr. The material is particularly useful as a wound covering material where such water permeability corresponds to the elevated water loss from open wounds and allows the wound to heal without desiccation or water accumulation under the covering.
