Abstract: A recirculation device of an extracorporeal blood treatment device is disclosed with a preferably universal medical fluid container to which an arterial line section of a fluid conducting system of the extracorporeal blood treatment device can be connected as an option. Furthermore, the recirculation device has a 3-way switch, preferably a 3-way valve, which is arranged directly downstream of the universal medical fluid container. A conduit of the 3-way switch is preferably coupled with a spike or a similar connecting device or is formed in one piece together with it.

Abstract: Disclosed is a filling device of a fluid conducting system of an extracorporeal blood treatment device that includes a spike for connecting to the single fluid connector of a medical fluid container and a manually operable fluid blocking mechanism arranged directly downstream of the spike that fluidly connects with the spike while the filling device is in operation. The fluid blocking mechanism has at least one fluid outlet connector that is adapted so that a line section or hose of the fluid conducting system such as the arterial line section of a blood purification device can be connected to it in a detachable manner while the filling device is in operation.

Abstract: Disclosed is a filling and recirculation device of a fluid conducting system for blood treatment which has a fluid connector and a three-dimensional four-way valve with a first valve plane on which an inlet connector for the fluid container, an arterial line connector, and a valve-internal coupling connector are arranged and a second valve plane on which an outlet connector and a venous line connector are arranged. The venous line connector is permanently connected with the valve-internal coupling connector. A manually operable valve rotary piston of the four-way valve has a first control section assigned to the first valve plane and a second control section assigned to the second valve plane.

Abstract: Disclosed is an anti-contamination device for preventing contamination of a fluid stored in a fluid container with a spike and a manually operable fluid blocking mechanism arranged directly downstream of the spike. A non-return valve is arranged between the spike and the fluid blocking mechanism, and that valve is adapted to allow only a flow from the spike in the direction of the manually operable fluid blocking mechanism.

The filling device includes a spike that is adapted for connection to a single fluid connector of a medical fluid container of the fluid system and a manually operable fluid blocking mechanism that is arranged directly downstream of the spike and is adapted or provided in such a way so as to remain fluidly connected with the spike while the filling device is in operation. The fluid blocking mechanism has at least one fluid outlet connector that is adapted so that a line section or hose of the fluid conducting system, preferably an arterial line section of a blood purification device, can be connected to it in a detachable manner while the filling device is in operation.

Abstract: A device for removing substances from blood or other body fluids, comprising a bundle of semi-permeable hollow fibers, the ends of which are embedded and held in a pottant, and a tubular casing surrounding the hollow fiber bundle. At the ends of the casing, inlet and outlet pipes are connected with partitioned fluid chambers formed in the casing. Different aspects are provided to improve the flow properties, for increasing the filtering efficiency, such as varying packing density along the length of the fiber bundle, a distributor disc within a cap, apertures on the circumference of the pottant and an ordered structure of the rippling of the hollow fibers.
