  • Patent number: 8162915
    Abstract: A connector for packings containing medical liquids, particularly infusion, transfusion or enteral bags, comprises a connecting part (1) for accommodating a spike for drawing out the liquid and comprises a closure part (3) that closes the passage (2) inside the connecting part (1). The connecting part (1) has an elastically deformable pinching off part (4) provided in the form of a tubular section with a non-circular cross-section. A base part (5), which widens on both sides is adjoined to said pinching off part (4) and can be integrated in the packing. During manufacturing, the packing is filled with liquid via the connecting part. After filling, the pinching off part is pressed together whereby preventing liquid from escaping. Afterwards, the closure part is placed onto the connecting part. The manufacturing of the packing is simplified by virtue of the fact that an additional tube for connecting the connector and packing is rendered unnecessary.

  • Publication number: 20080230467
    Abstract: 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.
