Wound dressings comprising a synergistic combination of reagents comprising a blend or mixture having effective amounts of chitosan and alginate to provide an absorption capacity for wound exudate far greater than that obtainable with the same amount by weight of either chitosan or alginate alone, along with the inherent hemostatic properties of the alginate and the other biological properties of the reagents including, but not limited to fungistic and bacteriostatic properties as well as the ability to accelerate wound healing by inducing high migration of poly- and mononuclear cells toward the wound and rapid granulating tissue formation with abundant angiogenesis. The alginate and chitosan may be provided in the form of a powder, film, gel, foam or mixtures thereof. In addition to the alginate and chitosan, the wound dressing may and frequently will contain other reagents providing specific desired functions. The dressing may be applied directly to the wound surface or carried on a suitable substrate applied to cover the wound.
A wound dressing comprising a blend or mixture consisting of effective amounts of chitosan and alginate in a weight ratio within the range of about 5:1 to 1:5, wherein the chitosan and alginate are present in a form selected from the group consisting of a multilayered composite, a powder, a composite fiber, a film, a gel, a foam or a mixture thereof.
A wound dressing comprising effective amounts of chitosan, alginate and collagen, wherein the physical forms of the chitosan, alginate and collagen are not all the same, and wherein the chitosan and alginate are present in a chitosan:alginate ratio of about 5:1 to about 1:5.
A wound dressing comprising a non-woven fabric having a mixture of alginate fibers and chitosan fibers obtained by wet spinning techniques, in an alginate:chitosan weight ratio of about 5:1 to about 1:5.
