Abstract
Membranes suitable for use as wound dressings and in particular as synthetic skin substitutes are disclosed. The membranes consist of a natural or synthetic polymer, a non-gellable polysaccharide and a cross-linking agent. The membranes of the invention may contain one or more additional components selected from water-loss control agents, emulsifying agents and plasticizers. An internal reinforcing material may also be provided to supplement the inherent mechanical strength of the membrane. Methods of forming such membranes are also disclosed.
Claims19
A membrane suitable for use as a synthetic skin substitute consisting essentially of a polyacrylamide network and a non-gellable polysaccharide dispersed evenly throughout said network, wherein said polymeric polyacrylamide network comprises acrylamide monomers cross-linked together by a cross-linking agent and wherein the membrane has a water absorptive capacity greater than of a membrane which includes an amount of a gellable polysaccharide in substitution for the same amount of non-gellable polysaccharide, but which is otherwise the same.
