Abstract: Novel bandage materials are provided comprising a transparent fluid mater consisting of hydrophilic organic transparent gel in sheet or band form, swollen with an aqueous solution which can contain buffer substances, wound treatment agents, nutrients and/or hormones, and optionally, a reinforcing mesh. The fluid bandages are made by dissolving a monomer and a gellable hydrophilic high molecular substance in aqueous medium and starting the gel forming reaction with an initiator for the polymerizable monomer. The bandages can also be utilized as carrier compositions for cell cultures from which metabolites are obtained.

Abstract: The present invention provides a wound treating agent in powder form based on a swellable organic polymer, which comprises a cross-linked polymer of a hydrophilic acrylic or methacrylic acid derivative, which polymer is permeated by a gellable polysaccharide and/or protein or polypeptide, the agent being obtainable by polymerizing a hydrophilic acrylic or methacrylic acid derivative in the presence of a dissolved, gellable polysaccharide and/or protein or polypeptide and of a cross-linking agent.The present invention also provides a process for the production of this wound treating agent, wherein a hydrophilic acrylic or methacrylic acid derivative is polymerized in an aqueous solution of a gellable polysaccharide and/or protein or polypeptide in the presence of a cross-linking agent and of a conventional polymerization initiator, to give a transparent gel which is dried and pulverized.
