Blood is pumped through one conduit by a roller pump (21) and dialysate is pumped in counter current through the other conduit by a roller pump (24).
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.
A roller pump in which operation of attaching/detaching an elastic tube is facilitated and pump discharge is properly controlled.
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.
The oxidizer gas pump may be a positive displacement pump such as a vane pump, a lobe pump, or a screw pump; or it may be a controlled blower.
