Abstract
The device preferably designed for the filtration of blood comprises one or more gap-shaped filter chambers (20) which are formed by a multiplicity of flow channels which are delimited on at least one side by a filter medium (7). The latter is supported on a dimensionally stable material layer (6) forming a multiplicity of elevations, producing an undulating surface. The blood to be filtered passes through the device via a feed (1) and a discharge (3). The dimensionally stable material layer (6) possesses an incompressible, woven-fabric-like structure or is designed in an incompressible woven fabric. The elevations have a height of between 0.1 and 0.5 mm and a spacing of up to 2.5 mm to adjacent elevations.
