Abstract
The dressing for a chronic wound with biological liquid, comprises a matrix of calcium alginate associated with at least one alginate of a multivalent metal, with the exception of magnesium. The multivalent metal alginate is produced from sodium alginate which is extruded through a die disposed in a coagulation bath of a soluble salt solution of the multivalent metal. The multivalent metal alginate is associated with the calcium alginate matrix by means of a textile technique.
