| 20090301961 | Hollow Fiber Membrane Separation Device - The present invention refers to a hollow fiber membrane separation device with two flow spaces, of which a first space is formed by the capillary tube passages of a hollow-fiber bundle cast at its ends into a sealing compound, and a second space is formed by a housing enclosing the fiber bundle, wherein the first space is sealed off by caps, placed on the sealing compounds, with seals running over the peripheral areas of the sealing compounds, and wherein the housing, into which the hollow-fiber bundle is drawn, at each end of its casing has tooth-like or pinnacle-like projections formed by axial notches or indentations running out freely. According to the invention, the housing has, between the tooth-like or pinnacle-like projections, extensions extending from said projections and extending to the adjacent tooth-like or pinnacle-like projection. | 12-10-2009 |

| 20080230467 | FILTER DEVICE - A filter device for mass exchange between two media separated by a membrane providing a low-stress transfer of blood flow from the connection area of the filter device to the fibers of a hollow fiber bundle is disclosed. Relatively uniform utilization of the fibers is provided by a membrane in the form of a hollow fiber bundle whose fiber cavities form a first flow space, with at least one inflow or outflow chamber connected to the first flow space being provided for supplying a medium to the hollow fiber bundle or removing a medium from the hollow fiber bundle. The inflow or outflow chamber is adjacent to an essentially circular or semicircular channel which is designed to be open in the direction of the ends of the hollow fibers and is connected to an inlet or outlet of the filter device. The channel is arranged approximately centrally with the hollow fiber bundle and preferably has a cross-sectional area that decreases in the direction of flow, and also preferably has an outside diameter that is less than the diameter of the hollow fiber bundle. | 09-25-2008 |
