[0074] FIGS. 1 and 2 show a wound dressing (1) of the invention, comprising a suction/rinsing body (2) treated by the manufacturer with Ringer's solution, and a sheetlike backing material (3) on the side of the suction/rinsing body (2) facing away from the wound. The sheetlike backing material (3) is a two-layer material comprising a fluid-impermeable and water vapor-permeable outer layer (3a) composed of a polyurethane, and a perforated polyurethane film (3b) on the wound-facing side. The openings in the perforated polyurethane film (3b) have an approximately circular shape. On the wound-facing side, the polyurethane film (3b) is provided with a skin-compatible silicone adhesive (4). The openings in the film layer here are not obturated by the silicone adhesive.

[0075] On the wound-facing side, the wound dressing (1) has a first, one-part protective layer (5) made of polyester film in a thickness of 50 μm.

[0076] On the side facing away from the wound, the wound dressing (1) has a second protective layer (6), coated over its full area with an acrylate adhesive. The second protective layer has grip elements (7) at two edges. These grip elements (7) are formed of sections of material composed of polyethylene terephthalate, which are applied on the wound-facing side of the second protective layer (6) and are joined to the second protective layer (6) via the acrylate adhesive. The grip elements (7) are set off in terms of color from the second protective layer (6). The second protective layer (6) is separated in the middle into two parts by means of a serpentine separating line (8).

[0077] FIG. 3 shows a wound dressing of the invention as a further embodiment of the wound dressing described in FIG. 2. In this embodiment, the first and second protective layers (5, 6) are joined firmly to one another in a hingelike manner by means of a connecting element (9) at one edge side, with the legs (9a, 9b) of the hingelike connecting element (9) being fastened respectively on the outer sides of the two first and second protective layers (5,6) joined to one another.

[0078] FIG. 4 shows packaging (10) of the invention with a wound dressing (12). The wound dressing is a wound dressing (12) for wound treatment in a moist or wet environment, embodied as what is called an island dressing. The wound dressing (12) comprises a) a suction/rinsing body (2), treated by the manufacturer with a saline aqueous solution, b) a sheetlike backing material (3), which is disposed on the side of the suction/rinsing body (2) facing away from the wound and which overhangs the suction/rinsing body (2) in such a way as to form, surrounding the suction/rinsing body (2) on all sides, an edge which on the wound-facing side is provided with a layer of a skin-compatible adhesive, and c) a protective layer which lines the layer of the skin-compatible adhesive on the wound-facing side. The packaging is formed by a pouch (11) composed of a first section (11a) of material and a second section (11b) of material. The first and second sections of material are each films made of aluminum coated on the outside with polyester and on the inside with polypropylene. The first section (11a) of material has a depression, the shape of which is complementary to that of the suction/rinsing body (2) and the size of which is suitable for accommodating a suction/rinsing body (2) of a wound dressing (12) contained.
