Pump intended particularly to provide blood circulation, formed by the combination of a roller pump (1-5) and a helical pump with reciprocating circular motion (6-8), the fluid to be activated going first through the roller pump. This pump allows to provide for an extra bodily circulation. To provide for a heart assistance, the roller pump is connected through a by-pass to the inlet of the helical pump of which the drum is driven by a step by step electric motor, housed inside said drum. |
