Vacuum-assisted drainage system

A vacuum-assisted drainage system comprising

• a first porous pad that is permeable to liquids and has a through opening in which a fistula adapter is placed, a perforated film carrying the pad and the fistula adapter to be inserted into a wound, a cover film with which said perforated film is air-tightly connected and which covers the pad and the wound and ensures a substantially air-tight sealing around the wound, the cover film haying an opening that surrounds the fistula adapter (4) in a substantially air-tight manner, and
• a second porous pad that is permeable to liquids and is positioned on the cover film with a part of the second pad directly above the first pad, a sealing film covering the second pad and providing a substantially air-tight connection to the cover film and around the wound, wherein
• air guiding routes are provided between the first pad and the second pad and pass through the cover film, and either
• an open drainage line is lying within the pad and can be connected with a suction pump so that liquids can be removed from the wound by suction, or
• positioned above the second pad is a drainage port with air guiding routes passing through the sealing film said drainage port communicating with an open drainage line that can be connected with a suction pump so that liquids can be removed from the wound by suction.
