The present disclosure relates to a medical pump drive comprising a pump housing and a pump motor provided in the pump housing. The pump drive also includes a rechargeable voltage source for storing electrical energy, or a rechargeable battery, for a voltage supply of the pump motor and a magnetic section for magnetically coupling of further pump sections, and/or for magnetically driving of elements, in particular a magnetically driven pump rotor. The pump also includes an electronic controller. The disclosure further relates to a pump, an induction charging station, a tube set, and a blood treatment apparatus.

Medical pump drive, pump and medical treatment apparatus

The present invention relates to a flow sensor for measuring a flow difference having at least two measurement chambers through which fluid is conductible; at least one means for producing a magnetic field for charge separation in a fluid flowing through the at least two measurement chambers; and at least one means for measuring an electric potential in the fluid flowing through the at least two measurement chambers, with the at least two measurement chambers being arranged such that they are run through by the same magnetic field line of the magnetic field for charge separation.

Dialyzer systems can consolidate multiple technologies and functionalities of blood treatment systems in a significantly integrated fashion. For example, this disclosure describes dialyzer systems that include a magnetically driven and magnetically levitating pump rotor integrated into the dialyzer. Such a dialyzer can be used with treatment modules that include a magnetic field-generating pump drive unit. In some embodiments, the dialyzers include pressure sensor chambers with flexible membranes with which corresponding pressure transducers of the treatment modules can interface to detect arterial and/or venous pressures.

Blood treatment systems

A filter module provides biotechnological filtration possibilities lessening the danger of contamination while achieving an optimum flow profile. The filter moduleincludes filter housinga filter with a bundle of hollow fibresand a centrifugal pump rotorThe filter is arranged in the filter housingsuch that the centrifugal pump rotorforces a biotechnological liquid into the interior of the hollow fibresvia an inlet flow path where liquid enters the filter module perpendicular to a longitudinal axis of the filter, flows into a hollow centre of the centrifugal pump rotor and is thereafter deflected to flow parallel to the longitudinal axis of the filter before entering the hollow fibers of the filter flowing parallel to the longitudinal axis. A filtration deviceincludes filter moduleand a drive unit for magnetically driving the centrifugal pump rotor

The invention relates to a medical treatment apparatus comprising a tube set, a peristaltic pumpfor conveying fluid, and a monitoring apparatusfor monitoring the occlusion of the positive displacement elementsA,B of the peristaltic pump. In addition, the invention relates to a tube setfor a medical treatment apparatus, and to a method for monitoring the occlusion of the occlusion elements of a peristaltic pump for conveying a fluid for a medical treatment apparatus. The invention is based on the fact that the occlusion of the positive displacement elementsA,B of the peristaltic pumpis monitored in order to monitor the fluid flow in the hose line. For this purpose, the electrical resistance or a variable which correlates with the electrical resistance is measured between a first and a second electrodeA,B, the first electrodeA being arranged on the hose lineupstream of the occlusion elementsof the peristaltic pumpand the second electrodebeing arranged on the hose line downstream of the occlusion elements such that an electrical contact is produced between the first and second electrodeA,B and the fluid flowing in the hose line. The electrodesA,B are preferably integral component parts of a connecting piece, by means of which the hose segmentA to be inserted into the peristaltic pumpis fixed in the form of a loop.
