Abstract: A peristaltic pump for conveying fluid in an extracorporeal blood treatment device includes a housing having a rotor with a rotor axis and a squeeze element in the pump bed. The housing also has a support surface extending arc-shaped about the rotor axis and spaced radially from the rotor. The support surface is arranged to support a tube segment insertable between the support surface and the rotor. The rotor has a swing arm for holding the squeeze element, which is pivotably movable and spring-mounted on the rotor, an insertion aid, with which the tube segment can be pressed into the pump bed during a threading process, and tube guiding elements, with which the tube segment is centrally aligned with the squeeze element. The insertion aid and tube guiding elements are integrated into the swing arm adjacent to the squeeze element in a rotational direction of the rotor.

Abstract: A peristaltic pump, specifically for pumping fluid in an extracorporeal blood treatment apparatus, includes a pump housing that accommodates a rotor rotatable about a rotor axis and a squeeze element. The pump housing includes a support surface extending in a curved shape around the rotor axis and being radially spaced from the rotor. The support surface can support a tube segment that inserted radially between the rotor and support surface. The rotor supports the squeeze element via a rocker mounted on the rotor in a pivotable and cushioned manner. The rocker supports an insertion aid by which the tube segment can be pressed into the pump bed, and tube guide elements by which the tube segment is centrally alignable to the squeeze element. The rocker is made from high-strength stainless steel with high chemical resistance and manufactured by powder injection molding, such as metal injection molding.

Abstract: A method and device for determining a division of a total insulation resistance and of a total system leakage capacitance in an ungrounded power supply system. The basic idea is to determine how the total insulation resistance is divided into partial insulation resistances and how the total system leakage capacitance is divided into partial system leakage capacitances between the active conductors of the ungrounded power supply system from displacement voltages measured between each of the active conductors of the ungrounded power supply system based on values determined in advance for the total insulation resistance and for the total system leakage capacitance of the ungrounded power supply system. By evaluating the displacement voltages in terms of their changes in amplitude, their frequency and their phasing, conclusions can be drawn as to the division of the total insulation resistance and of the total system leakage capacitance between the individual active conductors.
