DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

[0036] FIG. 1 is a top view of a covering device in the form of a transparent unilaterally open-celled film (1). Peripheral edge (1a) is provided with an adhesive, by means of which the film can be fastened to the skin. In the middle of the film, a circular opening (2) is located. The opening is delimited by a plastic ring (3), which is not fluid-conductively welded to the film. Adjacent to the ring, resting on the open-celled underside, an open-celled polyurethane foam (4) is located, which extends star-like across the film, using finger-like extensions (4a). The open-celled polyurethane foam is fluid-conductively connected to the open-celled side of the film. One of the finger-like extensions of foam (4b) is fluidly-conductively connected to a tube (5), which is connected to a vacuum-generating system (6).

[0037] FIG. 2a is a cross-sectional view of FIG. 1 at the level of the ring opening. The open-celled underside of unilaterally open-celled film (1) is deposited on a wound (20), which encloses a fistula opening (20a) to intestine (20b). In the edge area of film (1a), the film is glued down and terminates not fluid-conductively in the wound or skin. Above fistula opening (20a), ring (3) is set on. A fluid-conducting buffer arrangement in the form of an open-celled polyurethane foam abuts the ring. A tube (5) having an adhesive surface (5a) is glued onto the film. Across an opening (5b), the tube is fluid-conductively connected to the open-celled side of the film and to the open-celled foam, so that a vacuum can be applied.

[0038] FIG. 2b is the same cross-sectional view as FIG. 2a, with the difference that a vacuum was applied via tube (5) and, as a result thereof, open-celled polyurethane foam (4) has collapsed.

[0039] FIG. 3a is a top view of a covering device in the form of a transparent, unilaterally open-celled film (1). Peripheral edge (1a) is provided with an adhesive, by means of which the film can be fastened to the skin. In the middle of the film, a circular opening (2) is located. The opening is delimited by a plastic ring (3), which is not fluid-conductively welded to the film. Abutting the ring, resting on the open-celled underside, a circular open-celled polyurethane foam (4) is located. Foam (4) is fluid-conductively connected to a tube (5), which is connected to a vacuum-generating system (6). On the underside of the open-celled film, letters and numbers (7) made of polyurethane foam strips are applied. Because the film is transparent, they are visible. They are fluid-conductively connected to the film and collapse subject to the exertion of a negative pressure.

[0040] FIG. 3b is a cross-section of the film at the level of the letters or numbers, which are fluid-conductively glued to the lower surface in the form of strips of the film.

[0041] FIGS. 4 a/b/c show different cross-sectional profiles of solidly manufactured plastic ring (3). Unilaterally open-celled film (1) is attached to different locations of the ring, and polyurethane foams (4) of different heights abut the ring. The edge of film (1a) is not fluid-conductive and can be glued to a wound.

[0042] In FIG. 4a, ring (3) is a rectangular profile.

[0043] In FIG. 4b, ring (3) has an L-shaped profile comprising a narrow edge protruding over film (1). As a result thereof, gluing down of a stoma pouch is to be facilitated.

[0044] In FIG. 4c, ring (3) has a clamp-like, C-shaped profile. This profile is designed like the locking profile of stoma pouches so that a pouch could be directly pressed on here.

[0045] FIG. 4d is a cross-sectional profile of a plastic ring (3b), which is hollow and can be filled using a gas or a fluid via a channel (8), which is equipped with a valve (8a).
