Abstract

Die Erfindung betrifft eine peristaltische Pumpe, insbesondere zum Pumpen einer medizinischen Flüssigkeit, aufweisend ein Pumpenbett mit einer ersten Pressfläche und eine Mehrzahl von Presskörpern mit jeweils einer zweiten Pressfläche, wobei die Pumpe geeignet ist, einen zwischen die erste Pressfläche und die zweite Pressfläche einlegbaren okkludierbaren Schlauch in einem Quetschbereich der Pumpe zu okkludieren. Die erste und/oder die zweite Pressfläche weist ein in Schlauchrichtung verlaufendes Längsprofil (15) auf, dessen Querschnitt im Quetschbereich einen ersten Querbereich und einen zweiten Querbereich aufweist, wobei im Quetschbereich ein Abstand zwischen der ersten und der zweiten Pressfläche im ersten Querbereich geringer ist als im zweiten Querbereich.
