Abdominal wound dressing comprising joining means

Bandage set suitable for use in the negative-pressure therapy of the open abdomen, comprising

• i) a first bandage ply (11, 21, 31) having a first and a second side, as organ-protecting layer, the first side being intended for application to a wound base (3), more particularly exposed internal organs or the greater omentum, and the bandage ply having a surface area of from 2500 cm2 to 4000 cm2,
• ii) a second bandage ply (12, 22) provided separately from the first bandage ply and having a first and a second side, the first side of the second bandage ply (12, 22) being intended for application to the second side of the first bandage ply (11, 21, 31), and the second bandage ply (12, 22) having a surface area of from 500 cm2 to 2000 cm2,
• iii) a joining means by means of which the second bandage ply (12, 22), after application of the first ply to the wound base (3), more particularly exposed internal organs or the greater omentum, can be joined to the first bandage ply (11, 21, 31), making it possible to avoid movement of the first bandage ply (11, 21, 31) with respect to the second bandage ply (12, 22) as far as possible during the therapy and/or facilitating simultaneous removal of first (11, 21, 31) and second bandage ply (12, 22),
• iv) optionally an airtight covering film (6) for closing the wound space.

Product for use in the therapeutic treatment of the open abdomen on the human or animal body by means of negative pressure, comprising

• a first bandage ply (11, 21, 31) having a first and a second side, as organ-protecting layer, the first side being intended for application to a wound base (3), more particularly exposed internal organs or the greater omentum,
• a second bandage ply (12, 22) provided separately from the first bandage ply and having a first and a second side, the first side of the second bandage ply (12, 22) being intended for application to the second side of the first bandage ply (11, 21, 31),
