Abstract

Die Erfindung betrifft das Gebiet von Flüssigkeitspumpen in medizinischen Behandlungsvorrichtungen, insbesondere Dialysegeräte. Der Erfindung liegt die Aufgabe zu Grunde, Verfahren und Vorrichtungen derart auszubilden, dass die Arbeitsdrücke oder Flussraten der Flüssigkeitspumpen gewünschte Verläufe annehmen, insbesondere konstante Werte oder kontrollierten Profilen folgen. Gelöst wird diese Aufgabe, in dem der Arbeitspunkt einer peristaltischen Schlauchrollenpumpe aufgrund des Drehwinkels des Pumpenrotors eingestellt wird oder dadurch, in dem der Arbeitspunkt einer Zentrifugalpumpe einem Profil folgend eingestellt wird.
