Title (DE) PASSIV MAGNETISCH GELAGERTE BLUTPUMPE
(EN) BLOOD PUMP WHICH IS SUPPORTED IN A PASSIVELY MAGNETIC MANNER
(FR) POMPE D'ASSISTANCE CIRCULATOIRE MONTÉE SUR SUSPENSION MAGNÉTIQUE PASSIVE
Abstract:
(DE) Das vorliegende Schutzrecht betrifft unter anderem eine Blutpumpe (1), enthaltend einen Einlass (10), einen Auslass (11) sowie einen Rotor (2) zur Förde-rung von Fluid vom Einlass (10) zum Auslass (11), wobei der Rotor (2) innerhalb der Blutpumpe (1) radial passiv magnetisch gelagert ist und axial in eine Richtung (11) zumindest passiv magnetisch vorgespannt ist, so dass bei fluid- fördernder Drehung des Rotors (2) der Axialschub des Rotors entgegen der axial in Richtung des Auslasses wirkenden magnetischen Anziehung wirkt.
(EN) The present invention relates to, among other things, a blood pump (1), comprising an inlet (10), an outlet (11) and a rotor (2) for conveying fluid from the inlet (10) to the outlet (11), wherein the rotor (2) is supported within the blood pump (1) in a passively magnetic manner and is prestressed axially in one direction (11) in an at least passively magnetic manner so that, in the case of a fluid-conveying rotation of the rotor (2), the axial thrust of the rotor counteracts the magnetic attraction that acts axially in the direction of the outlet.
(FR) La présente invention concerne entre autres une pompe d'assistance circulatoire (1) comprenant un orifice d'admission (10), un orifice de refoulement (11) ainsi qu'un rotor (2) pour refouler un fluide ,de l'orifice d'admission (10) à l'orifice de refoulement (11), ledit rotor (2) étant monté radialement sur suspension magnétique passive à l'intérieur de la pompe d'assistance circulatoire (1) et étant précontraint axialement dans une direction au moins par voie magnétique passive, de manière que lorsque le rotor (2) est en rotation et refoule alors du fluide, la poussée axiale du rotor agit à l'encontre de l'attraction magnétique qui s'exerce axialement dans la direction de l'orifice de refoulement.
