Abstract: A peristaltic pump for extracorporeal blood treatment includes a pump housing in which a rotor is rotatable about a rotor axis. The rotor has at least two squeeze elements offset in a circumferential direction to each other. The pump housing has a support surface extending arc-shaped about the rotor axis and spaced radially from the rotor. The support surface is configured to support a tube segment which is radially insertable between the rotor and the support surface. In order to extend the service life of the pump and reduce fluctuations in the pump volume, the pump has co-rotating guide surfaces arranged and configured adjacent to both sides of the squeeze element in the circumferential direction in such a way that they each form a circular segment-like guiding passage with the support surface, in which the tube segment can be fixed radially with a predetermined clearance fit.

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 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 for conveying fluid in an apparatus for extracorporeal blood treatment includes a pump housing that accommodates a rotor. The rotor includes squeezing elements offset against each other in the circumferential direction. The pump housing includes a support surface extending in a curved shape around the rotor's axis. The support surface is radially spaced from the rotor and arranged to support a tube segment radially inserted between the rotor and the support surface. The rotor is driven by a rotor shaft, the rotary movement of which can be transmitted to a rotor base body via a freewheel press-fitted into a toothed driver sleeve. The freewheel has bearing positions for the rotor base body on both sides of the freewheel. To ensure coaxiality between the freewheel and the bearing support of the rotor base body, the bearing positions are defined by the geometry of the finished driver sleeve.

Abstract: A peristaltic pump for extracorporeal blood treatment has a pump housing that accommodates a rotor. The rotor is rotatable about a rotor axis. The pump also includes at least two squeeze elements offset in a circumferential direction to each other. The pump housing has a support surface extending arc-shaped about the rotor axis and spaced radially from the rotor. The support surface is configured to support a tube segment inserted radially between the rotor and the support surface. In order to simplify the manual unthreading of the tube segment and thereby largely protect the tube segment, the peristaltic pump has a sliding edge arranged adjacent to the respective squeeze element against the rotational direction of the rotor, extends toward the support surface, is connected to the rotor in a rotationally fixed manner, and can be gripped from below by, or under reached by, the inserted tube segment.

Abstract: A dialysis machine includes a leakage construction having a leakage collecting device and a leakage connector. The leakage connector is preferably a leakage adapter arranged between an opening of the leakage collecting device and a hose. The leakage connector has a main body to which a seal is attached, which can be brought into sealing contact with the leakage collecting device.

Abstract: A medical appliance for use in extracorporeal blood treatment. The appliance includes a housing component, a cover and a pivot bearing arrangement by which the cover is mounted on the housing component. The cover is pivotable between a covering position, in which the housing component is covered, and a exposure position, in which the housing component is exposed. The pivot bearing arrangement has pivot bearings, each having a bearing element and a bearing element receptacle. The cover can move linearly relative to the housing component between a dismounting position, in which at least one of the bearing elements is disengaged from a bearing element receptacle, and a bearing position, in which both bearing elements engage the bearing element receptacles. The cover is mounted resiliently and elastically preloaded relative to the housing component by a spring arrangement.
