Abstract
The present invention relates to a pulsatile positive-displacement pump with a flexible positive-displacement diaphragm which is operated pneumatically and by whose movement the blood is aspirated and displaced. A mechanical switching device in the interior of a drive unit ensures an autonomous operation of the blood pump, wherein no electricity or electronics system is needed.
