IMPROVEMENTS IN OR RELATING TO WOUND DRESSINGS

摘要

Materials suitable for use as wound dressings may be made by mixing under low-shear conditions from 2 to 10 parts by weight of polymer solids, the polymer solids consisting of at least 50 percent by weight of a water-swellable cellulose ether fibre and no more than 50 percent by weight of a water-swellable or water-soluble polymer in powder form, with correspondingly from 98 to 90 parts by weight of an aqueous liquor. The aqueous liquor may contain sodium chloride, and may contain from 5 to 30 percent by weight propylene glycol. Materials produced by the method of the invention take the form of viscous pasty materials of good handlability, integrity and absorbency.
