The device comprises an air-impermeable cover material (1) for air-tight closure of a wound (5) and of a wound environment, an element for functional connection of a wound space (4) to a source of vacuum located outside the cover material so that a vacuum is established in the wound space to suction liquids out of the wound space, an activated absorbent/rinsing body (3) that contains a superabsorbent polymer for insertion in an interstice formed between a wound surface (2) and the cover material, and a wound contact layer for inclusion in the interstice.

The superabsorbent polymer consists of particles or fibers. The activated absorbent/rinsing body is: an absorbent/rinsing body surrounded by a textile envelope and made of stable volume; and an enveloped air-laid. The activated absorbent/rinsing body contains 500 wt.% of an aqueous synthetic activation solution, which has a pH value of 4-9, a viscosity of 0.8-150 mPa.s at 20[deg] C, inorganic cations and/or anions, organic anions, antimicrobial substances and added bioorganic compounds. The activation solution is Ringer's solution. The activated absorbent/rinsing body exhibits a reduction in volume during wound treatment relative to a volume at a be
