Abstract

The absorbing wound dressing which is atoxic, tissue compatible and very well adjusted to the shape of the wound, it is easily removable, protecting from infections or reduces infections in that it absorbs, in addition to the wound excudate, bacteria, fungi, toxins, proteins and inflammation mediators and which is therefore suitable for covering and cleaning of strongly wetting, infected wounds, as well as effected areas in skin and tissue diseases, consists of potentially macroporous particulate mixtures of regenerated cellulose and a carboxylate groups containing polysaccharide derivative. For making it, viscose solutions, which contain the polysaccharide derivative are thermically coagulated, purified and dried, after the deformation.
