A wound dressing material comprising a low-moisture hydrogel matrix having oxidized cellulose distributed therein. For example, a matrix of dried sodium carboxymethylcellulose gel having fibers of oxidized regenerated cellulose dispersed therein. Also provided are the use of such materials in the treatment of wounds, and the manufacture of such materials by drying aqueous gels containing dispersed particles of oxidized cellulose. The hydrogel may comprise modified celluloses or starches alginates, plant gums, gelatins, glycosaminoglycans, polyacrylates or polyurethanes, with suitable plastizers. |
