Zusammenfassung:	A device for oxygenating or dialyzing blood has elementary units comprising pairs of frames having rectangular openings and a gas permeable membrane on each face. Two confronting membranes define a thin passageway for blood. Remote sides of the membranes confront a porous support structure in a second passageway in which another fluid such as dialysate or oxygen enriched gas flows. The second passageway contains a flat screen wrapped in a fibrous material which distributes the gas uniformly and supports the membranes when the space between them is pressurized with blood. The frames have apertures for conveying blood or other fluid to respectively alternate passageways. Thermoplastically formed protuberances project integrally from the membranes into the blood space for agitating the flowing blood film.
