Abstract: A composite material is described, which is of particular use in wound treatment, and to a method for producing said composite material is also described. The composite material has a first foam layer having a first hydrophilic polyurethane foam material, and, in immediate contact therewith, a second foam layer having a second hydrophilic polyurethane foam material, which second hydrophilic foam material is different from the first hydrophilic foam material.

Abstract: A method for manufacturing a wound dressing having a substrate, and a wound dressing manufactured by such a method are described. The method has a step of providing a sacrificial layer of material to be perforated by means of a hot pin perforator, in order to remove any molten residues on the heated pins of the hot pin perforator, before the same pins are used to make holes in the substrate. The presented method is cost effective, robust and reduces the risk of contaminating substances being embedded in the substrate during the hole making process.

Abstract: Disclosed is a method for making a composite material, which is of particular use in wound treatment. The composite material has a hydrophilic polyurethane foam material with a first polyurethane polymer; a hydrophilic fiber material having a second polymer, wherein said second polymer is not a polyurethane polymer and wherein said fiber material is capable of absorbing and retaining a fluid. The first polymer is covalently bonded to the second polymer.

Abstract: The present invention relates to a composite material, which is of particular use in wound treatment, and to a method for producing the same composite material. Said composite material comprises a hydrophilic polyurethane foam material comprising a first polyurethane polymer; a hydrophilic fiber material comprising a second polymer, wherein said second polymer is not a polyurethane polymer and wherein said fiber material is capable of absorbing and retaining a fluid. In the composite material according to the present invention, said first polymer is covalently bonded to said second polymer.

Abstract: Wound pads and systems and kits comprising wound pads whose total thickness can be modified by a user without the use of tools, comprising a plurality of separable layers having layer thicknesses less than the thickness of the wound pad. The wound pads may be used as wound fillers in the context of negative pressure wound therapy (also known as “vacuum treatment”, “reduced pressure” treatment).

Abstract: An absorbent article, such as a wound pad, comprising a body of compressed thermoplastic or thermo-set open-celled foam is described, wherein the body has a pattern of ultrasonically made depressions in two opposite sides thereof, the depressions in the opposite sides being coaxial to each other and separated from each other by a common bottom portion which is compressed to a higher extent than the remaining parts of said body. A method for manufacturing such a body is also described.
