Abstract
The invention provides a wound dressing material comprising a complex of an anionic polysaccharide with silver, wherein the material comprises from about 0.1 wt. % to about 3 wt. % of silver. Also provided are wound dressings comprising such materials, and the use of such materials in medicine.
Claims18
A wound dressing material comprising a complex of an oxidized regenerated cellulose with silver, wherein the amount of silver in the wound dressing material comprises from about 0.1 wt. % to about 0.3 wt. % silver.
A method for treating venous ulcers, decubitis ulcers or diabetic ulcers, comprising applying a wound dressing material directly to the surface of the wound;
- wherein the wound dressing material comprises a complex of oxidized regenerated cellulose with silver, wherein the amount of silver in the wound dressing material comprises from about 0.1 wt. % to about 0.3 wt. % silver.
A method of making a wound dressing comprising the steps of:
- forming a complex of oxidized regenerated cellulose and silver;
- and
- combining the complex with oxidized regenerated cellulose and collagen;
- wherein the wound dressing comprises a cell proliferative amount of silver.
A wound dressing material comprising a complex of an oxidized regenerated cellulose with silver, wherein the amount of silver in the dressing material comprises a cell proliferative amount of silver in the amount of from about 0.05 wt. % to about 0.3 wt. % silver.
