The disclosure relates to a wound dressing comprising a fibre fleece-based body, and a packaging forming the outer visible sides of the wound dressing, which packaging contains a layer made from a flat textile on the side of the wound dressing facing the wound, which has an outer-side, partially and structurally applied coating, and wherein the packaging has a fibre fleece layer on the side of the wound dressing facing away from the wound, which forms the outer visible side of the wound dressing; and, a liquid-impermeable plastic film layer on the side of the fibre fleece layer facing the wound, and wherein the fibre fleece layer, the plastic film layer, the body and the textile layer are not connected to one another, but rather lie with the flat sides thereof loosely and movably against one another and are only connected along the peripheral edges by a joint connection.

The invention herein relates to a wound dressing product, combining a hydrophobic fabric, which is to be placed towards the wound, and is capable of binding unwanted microorganisms, and a moisture carrying matrix such as a gel or a foam. The product of the invention is ideal for treatment of drier wounds. It protects the wound and reduces the number of pathogenic microorganisms, without using antimicrobial substances and at the same time adds or traps moisture to the wound both supporting the hydrophobic functioning of the pad and healing in general by keeping the wound moist.

Also, multi-layered nonwoven wound dressings, containing (1) at least one inner layer containing (a) about 50% by weight to about 95% by weight (e.g., 50% to 95) non-scoured, non-bleached greige cotton fibers and (b) about 5% by weight to about 50% by weight (e.g., 5% to 50%) hydrophobic fibers, all percentages adding up to 100 wt %, and (2) at least one outer layer containing (a) about 5% by weight to about 95% by weight (e.g., 5% to 95%) non-scoured, non-bleached greige cotton fibers, (b) about 5% by weight to about 95% by weight (e.g., 5% to 95%) bleached cotton fibers, and (c) about 5% by weight to about 60% by weight (e.g., 5% to 60%) hydrophobic fibers (e.g., polypropylene, nylon); all percentages adding up to 100 wt %.

A combined compression and absorption dressing/bandage, which includes a short stretch compression bandage and at least one absorptive wound dressing comprising at least one absorbent layer of a non-woven fabric of any one or more of cotton, viscose and polyester fibers, the absorbent layer having an operative inner face and an operative outer face, the at least one wound dressing being bonded to the short stretch compression bandage with its inner face towards the bandage and the outer face facing away from the bandage.

One subject of the present invention is a dressing essentially consisting of: an absorbent nonwoven compress formed from a mixture: of bicomponent thermal bonding non-absorbent fibers, of core-shell type, said core being made of polyester (polyethylene terephthalate, PET) and the shell being made of polyethylene; of bicomponent superabsorbent fibers of core-shell type with a core made of polyacrylonitrile and a shell made of polyacrylate; and a net fabric made from a hydrocolloid elastomer mass partially covering the face of the compress intended to come into contact with the wound. This product is especially intended to promote the healing of chronic wounds by optimizing the debridement.

A method (400) of manufacturing a wound dressing includes obtaining alginate fibers (108) and the step (404) of spraying either the alginate fibers (108) or a dressing or dressing layer (610) of the alginate fibers with an aqueous solution (801) comprising a polysaccharide, which can be carboxymethylcellulose. The step of spraying can occur while the alginate fibers, dressing, or dressing layer are wet. A step (405) of flash drying can follow to remove the solute of the aqueous solution to leave the polysaccharide along the alginate. The step of spraying can be selective, such that only portions of the dressing layer include the polysaccharide.

The invention relates to a wound dressing (2) for wound treatment in a damp environment, comprising a fiber fleece-based suction/irrigation body (4) in which super absorbent material is accommodated in a distributed manner, wherein the suction/irrigation body (4) is supplied with a salt-containing aqueous solution by the manufacturer, and comprising a packaging (6) forming the outer visible sides of the wound dressing, wherein the packaging (6) comprises a layer (9) made from a flat textile material on the side of the wound dressing facing the wound, wherein the layer (9) made from a flat textile material on the side facing the wound comprises an outer-side, partially and structurally applied atraumatically effective coating (22) having a degree of coverage of at most 70%, characterised in that the packaging (6) comprises a fiber fleece layer (12) on the side of the wound dressing facing away from the wound, which forms the outer visible side (14) of the wound dressing facing away from the wound, and in that a liquid-impermeable plastic film layer (16) is arranged on the side of said fiber fleece layer (12) facing the wound, and in that the fiber fleece layer (12), the plastic film layer (16), the suction/irrigation body (4) and the layer (9) made from flat textile material are not connected extensively to one another, but rather lie with the flat sides thereof loosely and movably against one another and are only connected with one another along the peripheral edges (18) of same by means of a joint connection.

A dressing including a film which is impermeable to fluids and permeable to water vapor, and the entire surface of which is covered by a perforated reinforcement coated with a medically acceptable adhesive which is the same or different on each of the faces thereof, the face opposite to the face in contact with the impermeable film of an adhesive being partially covered by an absorbent pad, The dressing further includes a layer for distributing the fluids which is positioned between the impermeable film and the perforated reinforcement.
