Abstract: A roller pump includes a stator with a pump bed formed therein, and a rotor for acting on a hose inserted into the pump bed in arcuate form. The ends of the hose are guided out of the pump bed in a crossed configuration.

Abstract: The invention relates to a roller pump consisting of a stator with a pump bed formed therein and a rotor for acting on a hose inserted into the pump bed in arcuate form. In accordance with the invention, the flow paths associated with the ends of the tube guided out of the pump bed cross.

Abstract: A reactor has a reactor unit with a first chamber and a second chamber, with the first chamber being formed by the interior of a housing and the second chamber being formed by the interior of a plurality of hollow fibers arranged in the housing. The hollow fibers are arranged in the housing such that their density in at least one region of the first chamber does not exceed 10 fibers/mm2, based on the cross-sectional area of the first chamber. The reactor unit can include two casting compounds, in which a portion of the hollow fibers are embedded and between which another portion of the hollow fibers extends. The length of at least some or all of the hollow fibers is at least 0.5% greater than the distance of the casting compounds.

Abstract: A membrane unit configured for use in a housing of a pressure measuring unit, preferably for measuring pressure in an extra-corporal blood circuit, has a flexible membrane and a fixing ring which is integral with the membrane so that the membrane and the fixing ring form a one-piece element. The fixing ring has a lower flexibility than the membrane, and has fixing elements for fixing the fixing ring to the pressure measuring housing.
