Super-soft foam materials, optionally for use as medical dressings, are provided. The pads are made of a foam prepared from NCO-terminated prepolymers in combination with an aqueous phase including fatty alcohols and alkyl polysaccharides. The foam may optionally contain at least one medicinal agent.

The present application is concerned with an improved wound dressing for use in the treatment of skin wounds with some level of exudation, especially for use in those wounds which are infected or under risk of being infected by microorganisms.

A medical dressing (30) is disclosed, comprising an adhesive layer (3) having a skin-facing surface (6) to adhere the medical dressing to a dermal surface, wherein said adhesive layer comprises a first chemical compound incorporated within said adhesive layer, and wherein at least a portion of said skin-facing surface comprises a coating (9) comprising a second chemical compound. Also disclosed is a method of manufacturing such a medical dressing.

A system for treating open wounds includes a foam material configured for pouring, spraying, injecting or spreading on a wound bed. The foam material can comprise a base component and a curing component, which can be pre-mixed before application, or mixed in situ as the components are being applied to the wound site. A third component can comprise a sacrificial porogen. Foam can be placed in the wound bed as a wound liner on the wound surfaces. An additional foam insulation can provide a foam filler partially contained by the wound liner and generally flush with a patient's epidermis. A method of treating open wounds includes the steps of applying the wound liner and filler components. An optional step comprises covering the wound liner with a semi-permeable (breathable) membrane and mounting inlet and outlet ports thereon for introducing healing compositions as input, and extracting wound exudates as output.

Foam wound inserts with high-density and low-density regions, methods for making wound inserts, wound-treatment methods, and wound-treatment systems.

A dressing includes a hydrophilic foam layer having a longitudinal central axis configured to overlay the incision, a drape coupled to an outwardly-facing side of the hydrophilic foam layer, a first row of superabsorbent material positioned on the outwardly-facing side of the hydrophilic foam layer, and a second row of superabsorbent material positioned on the outwardly-facing side of the hydrophilic foam layer. The first row and the second row are spaced laterally apart from, and on opposite sides of, the longitudinal central axis. The drape includes a first window aligned with the first row and a second window aligned with the second row. The first window and the second window include a film, different from the drape, configured to facilitate evaporation therethrough.

A dermal patch includes: an open-cell foam layer; and an adhesive layer arranged thereon and intended for contact with skin. At least a side of the foam layer facing the adhesive layer has macropores whose cavities are spanned at least partially by a barrier layer formed from the foam layer.

A medical dressing is disclosed, the medical dressing has an adhesive layer having a skin-facing surface to adhere the medical dressing to a dermal surface, wherein said adhesive layer comprises a first chemical compound incorporated within said adhesive layer, and wherein at least a portion of said skin-facing surface has a coating comprising a second chemical compound. Also disclosed is a method of manufacturing such a medical dressing.

The invention relates to a vacuum treatment array having at least one open-pored contact element, by way of which a negative pressure and/or suction can be generated in a body cavity, wherein the open-pored contact element is configured, at least in sections, in the manner of a tube, having an outer and/or inner boundary surface rotating around a tube axis, at least in part.
