Abstract:
1. A device for treatment of wounds using reduced pressure, said device comprising a pump capable of providing a reduced pressure, a gas barrier cover, a first compressible material adapted to elastically expand after compression, wherein said first compressible material contains voids, a second material capable of absorbing wound fluids in an amount several times its own weight and retain the absorbed wound fluids, wherein said first and second material are arranged inside the cover and form a reservoir connected to said pump, said device further comprising an inlet for connecting the reservoir with a wound so as to allow the pump to expose the wound to the reduced pressure, a wound pad to be arranged in the wound cavity, and a sealing covering the wound and said wound pad, wherein a third material is arranged around at least a major part of the first material, said third material having high liquid spreading capability, and that said second material is in the form of at least one layer arranged outside the third material and thereby separated from the first material by said third material.
