Abstract: A core (1), in the form of a cylindrical pack, of a dressing is surrounded by a sleeve (2, 3) for holding the mechanical structure of the core. The sleeve (2), which may be comprised of threads (2, 3), is permeable to biological fluid of wounds and is biologically compatible with wounds. The dressing is very suitable for deep wounds, from which it can easily be removed.
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.
