<p>Dressings for chronic wounds with a biological liquid (blood or exudate) comprise a matrix of calcium alginate associated with≥1 multivalent metal alginate, other than magnesium alginate. The multivalent metal alginate is prepared by extruding sodium alginate into a coagulating bath containing a solution of a soluble salt of the metal, using known textile manufacturing techniques. The resultant metal alginate is combined with calcium alginate to form a woven or nonwoven fabric, a flock, powder, thread, embroidery or ribbon. Calcium alginate is used especially with zinc, manganese, copper or selenium alginates.</p> |
