Abstract:
1. A liquid removal system which comprises an interface device, said interface device comprising a first zone and a second zone and having a porous membrane separating said first zone from said second zone, said second zone being adapted to be connected to a suction source, said porous membrane being capable of maintaining a suction in said second zone without permitting air from said first zone to pass through said membrane into said second zone when said membrane has been wetted with a first liquid; said suction being maintained until said membrane is contacted with a second liquid; and wherein said second liquid upon entering said first zone and contacting said porous membrane is removed from said first zone by said suction in said second zone by passing through said membrane into said second zone said first zone having a user facing surface, said second zone having a back surface, characterized in that said interface device is compressible in the longitudinal direction and/or is compressible in the transverse direction to less than 90 percent of its original dimension in that direction, wherein said second zone comprises a flexible support means and said second zone is enveloped by a flexible, liquid impermeable backsheet, wherein said flexible support means comprises a plurality of substantially incompressible elements, at least a portion of said plurality of substantially incompressible elements being freely movable inside said second zone.
