Abstract: A method of producing a hydrophilic polyurethane foam structure containing inert activated carbon particles, includes the steps of: (a) providing a water phase containing a surfactant and dispersed inert particles; (b) providing a isocyanate-terminated polyether having functionality of more than 2; (c) mixing the water phase and the isocyanate-terminated polyether, immediately transferring the resulting mixture to a mold or a continuous web, whereby a foam structure is obtained; and (d) drying the foam structure until it has a moisture content of at most 10% (wt). A foam structure produced by the method and a wound dressing containing the foam structure are also disclosed.

Abstract: The present invention pertains to antimicrobial compositions comprising inter alia at least one alkenyl- and/or alkynyl-substituted polysiloxane, at least one polysiloxane comprising silicon-bonded hydrogen atoms, and at least one hydrosilylation catalyst, as well as antimicrobial silicone gels, wound dressings, and methods of preparing the above.

Abstract: Wound care product which comprises a substance which inhibits the growth of bacteria in wounds. The invention is characterized by the fact that the substance is xylitol. The invention also relates to the use of xylitol in wound care products and to the use of xylitol for producing a composition which has a growth-inhibiting effect on bacteria in wounds. The invention furthermore relates to a method for manufacturing wound care products which contain xylitol.

Abstract: A wound dressing includes an hydrophilic foam layer which is coated with a liquid-permeabe adhesive layer on one side. The dressing includes an absorbent layer disposed on the foam layer on the side opposite to the adhesive coating, wherein absorbent layer is able to drain the foam layer through the action of capillary forces, and wherein the dressing further includes elements that ensure effective contact between the absorbent layer and the foam layer.

Abstract: The present invention relates to a wound dressing that includes a carrier layer which is coated on one side with an adhesive elastomer (3). According to the invention, the carrier layer has the form of a laminate which consists of a plastic film (1) and a material (2) that has an irregular surface structure.

Abstract: The invention relates to a method and to an apparatus for perforating a web of material intended to form an outer casing sheet of absorbent articles. As the web is advanced, the web is first provided with a large number of mutually separated cuts in the nip defined between raised plateaus on a matrix cylinder and circumferentially extending knife-edges of a cutting cylinder. The web is then deformed transversely to its plane at parts which border on each cut. The invention also relates to a perforated outer casing sheet which includes recesses in the form of mutually adjacent elongated channel-like grooves.

Abstract: A wound dressing (1) comprising a layer of absorbent foam material (2) which includes a pattern of holes (4). The holes open out on that side of the foam material which lies proximal to the wearer's skin when the dressing (1) is worn, and the layer of foam material is coated with a layer (3) of skin-adhering hydrophobic gel, wherein those end parts of the walls of the holes in the foam material that lie proximal to the wearer's skin when the dressing is worn are gel coated. A method of producing such a dressing is also disclosed.
