Abstract

The invention relates to a drainage system to be used with an open wound, which system consists of a block of a porous, moisture absorbing material, which is connected to a tube or hose, which is in turn connected to a suction unit, which porous material is covered with a foil, wherein an element consisting of a plate-shaped member is provided on the porous, moisture absorbing material, the plate-shaped member being provided on the upper side with a partially open thickening for placing or inserting the tube or hose, which thickening is provided on the underside with one or more openings, which open into and cooperate with openings in the plate shaped member. The invention furthermore relates to the element and to a method of using the drainage system.

Claims

1. A component for use with an open wound drainage system, said drainage system comprising a block of a porous, moisture-absorbing material, said component comprising a plate-shaped member having an upper side and an underside, and a partially open hollow thickening member, said thickening member being directly disposed on said upper side of said plate-shaped member, said component being disposed on said block, said block being connected to a tube or to a hose via said partially open hollow thickening member through which a suction force may be applied to said tube or hose, wherein said thickening is closed at one end and open at the other end, so that a hose or a tube can be inserted into or applied on said open end.

2. A component for use with an open wound drainage system, said drainage system comprising a block of a porous, moisture-absorbing material, said component comprising a plate-shaped member having an upper side and an underside, and a partially open hollow thickening member, said thickening member being directly disposed on said upper side of said plate-shaped member, said component being disposed on said block, said block being connected to a tube or to a hose via said partially open hollow thickening member through which a suction force may be applied to said tube or hose, wherein projections are provided on said underside of said plate-shaped element, said projections guiding fluids emanating from said block of the porous material to said openings of said thickening.
