Embodiment Construction

[0027] figure 1 The wound dressing 2 is shown in section. It comprises a nonwoven-based suction / irrigation body 4 . The fiber base involves a preferred mix of cellulose fibers (cellulose) and polypropylene fibers or polypropylene / polyethylene fibers placed in the air. These fiber mixtures are superabsorbent polymer material (SAP) mixed as uniformly as possible in the form of granules or in the form of fibers, wherein the SAP fraction accounts for preferably 40-50% by weight of the total mass of the suction / irrigation body 4 . The average particle size of the SAP particles is, for example, between 150 and 850 μm (eg polyacrylate Favor pac 300 from Evonik Stockhausen GmbH).

[0028] The suction / irrigating body 4 is surrounded by a wrapping 6 forming the outside of the wound dressing, which is composed of an envelope 8 facing the wound and two envelopes 10a, b facing away from the wound. The wrapping layer 8 facing the wound is preferably a layer 9 made of a textile surface ma...

Abstract

The invention relates to a wound dressing (2) for wound treatment in a damp environment. The wound dressing comprises a fibre fleece-based suction / irrigation body (4) in which a super absorbent material is accommodated in a distributed manner, wherein the suction / irrigation body (4) is supplied with a salt-containing aqueous solution, particularly a Ringer's solution, preferentially a solution comprising antibacterial compounds, by the manufacturer, and comprises a packaging (6) forming the outer visible sides of the wound dressing. The packaging (6) comprises a layer (9) made from a flat textile material, especially a braided fabric, a textile fabric or a fabric, on the side of the wound dressing facing the wound. The layer (9) made from the flat textile material on the side facing the wound comprises an outer-side, partially and structurally applied atraumatically effective coating (22) made of silicone preferentially and having a degree of coverage of at most 70 %. The wound dressing is characterized in that the packaging (6) comprises a fibre 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, a liquid-impermeable plastic film layer (16) is arranged on the side of the fibre fleece layer (12) facing the wound, and the fibre fleece layer (12), the plastic film layer (16), the suction / irrigation body (4) and the layer (9) made from the 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.

Description

technical field [0001] The invention relates to a wound dressing for treating wounds in a moist or wet environment, with a suction / irrigation body based on a nonwoven, in which superabsorbent material is distributedly accommodated, wherein the suction / irrigation body The rinsing body is applied at the manufacturer with a saline solution, in particular Ringer's solution, which preferably contains substances with an antibacterial effect and has a coating which forms the outer visible side of the wound dressing, wherein the coating is located on the wound dressing The side facing the wound comprises a layer made of a textile surface material, in particular a knitted fabric, a braid or a woven fabric, wherein the layer made of a textile surface material has an outer part on the side facing the wound and a structure The applied, atraumatic coating, preferably made of silicone, has a coverage of up to 70%. Background technique [0002] Such wound dressings are known from WO 2011 / ...
