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.

Particle-containing foam structure

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.

Antimicrobial gels

A method of producing a hydrophilic polyurethane foam structure containing a silver salt, chosen from the group of silver sulphate, silver citrate, silver acetate, silver carbonate, silver lactate and silver phosphate, or a mixture of these salts includes the steps of (a) providing a water phase containing a surfactant, and at least one silver salt, wherein the at least one silver salt is dispersed in the water phase; (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 mould whereby a foam structure is obtained; and (d) drying the foam structure until it has a moisture content of at most 10% (wt). The hydrophilic polyurethane foam structure produced by the method and a wound dressing containing the foam structure are also described.

Silver-containing foam structure

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.

Wound dressing

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

A wound dressing (,) comprising a layer of absorbent foam material (,) which includes a pattern of holes (,). The holes open out on that side of the foam material which lies proximal to the wearer's skin when the dressing (,) is worn, and the layer of foam material is coated with a layer (,) 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.

Wound dressing and manufacturing method therefor

The invention relates to an absorbent body for use in diapers or like articles. The invention is characterized in that the absorbent body includes a first layer of fluff, a first superabsorbent mixed in the fluff layer and having a high degree of cross-linking, and in that the absorbent body includes a second layer which contains a second superabsorbent having a higher liquid absorbency than the first superabsorbent.
