Claims20
A unitary wound dressing comprising:
- an absorbent core;
- a backing layer defining a distal surface, a proximal surface, a center portion and a border portion bordering the center portion;
- and
- a woven or non-woven fabric layer comprising an agent having an effect against pathogenic microbial colonization of a wound, the woven or non-woven fabric layer defining a distal surface, a proximal surface, a center portion and a border portion;
- wherein the woven or non-woven fabric layer is bonded to at least a part of the border portion of the proximal surface of the backing layer, wherein the non-woven or woven fabric is not bonded to the absorbent core, wherein the agent having an effect against pathogenic microbial colonization of a wound comprises a hydrophobic material and is non-releasably incorporated to the fibers of the woven or non-woven fabric layer;
- a carrier layer secured to the woven or non-woven fabric in at least a part of the border portion thereof and having at least an opening through which fluid can pass from the wound into the absorbent core,
- a skin adherent facing layer secured to the proximal side of the carrier layer, the skin adherent facing layer comprising a crosslinked silicone gel adhesive,
- a retention layer comprising superabsorbent material distributed homogenously in a wicking material matrix, wherein the retention layer is a film that is placed over the distal surface of the absorbent core,
- wherein the retention layer is elastomeric and pliable and the wicking material matrix is formed by a hydrophilic material.
