Embodiment Construction

[0033] figure 1 A section through the wound dressing 2 is shown. It comprises an absorbent / rinsing body 4 based on nonwoven. The fiber base is a preferred mixture of airlaid cellulose fibers (cellulose) and polypropylene fibers or polypropylene / polyethylene fibers. For this fiber mixture, superabsorbent polymer material (SAP) in granular or fibrous form is mixed as homogeneously as possible, wherein the SAP fraction represents preferably 40% to 50% by weight of the total mass of the absorbent / rinsing body. The average particle size of the SAP particles is, for example, 150 μm to 850 μm (for example polyacrylate under the trade mark Favorpac 300 from the company Evonik Stockhausen GmbH).

[0034] The absorbent / rinsing body 4 is surrounded by an outer covering 6 forming the wound dressing, consisting of a wound-facing covering 8 and a wound-facing covering 10 , the coverings being connected to one another at the edges. The covering layer 8 facing the wound is preferably a br...

Abstract

The invention relates to a wound dressing (2) for treating wounds in a moist environment or in a moist environment, which has an absorbent / rinsing body (4) based on nonwoven fabric, in which super Absorbent material, wherein the absorbing / rinsing body (4) is applied at the manufacturer's place with a saline solution, especially Ringer's solution, preferably until saturated; and has a covering (6) forming the externally visible side of the wound dressing, wherein On the side of the absorbent / rinsing body (4) facing away from the wound, a film layer to prevent evaporation can be provided; the wound dressing is improved by the aqueous solution comprising a pH value of 4-7.5 in a typical wet or humid wound environment A cationic substance with an antibacterial effect is drawn attractively by the anionic groups of the cationic superabsorbent material and thus plays an antibacterial effect in the absorbent / rinsing body (4), and the covering (6) is There is a partially and structurally applied damage-protective coating ( 16 ) on the outer side, which has a coverage of up to 70%.

Description

technical field [0001] The invention relates to a wound dressing for treating wounds in a wet environment or in a humid environment, having an absorbent / rinsing body based on a nonwoven, in which superabsorbent material is contained in a distributed manner, wherein The absorbent / rinsing body is applied at the manufacturer with a saline-containing aqueous solution, especially Ringer's solution, preferably until saturated; and has a wrap forming the externally visible side of the wound dressing, wherein on the side of the absorbent / rinsing body facing away from the wound A film layer to prevent evaporation can be provided on it. Background technique [0002] Such a wound dressing is known from EP0594034B1 by the applicant. This is a wound dressing in the form of a wound pad or compress, which can be applied to wounds or can also be used to block deep wounds. The absorbent / rinsing body is preferably saturated at the manufacturer with a saline-containing aqueous solution, whic...
