Abstract
A stand alone blood pump which can be used with different types of oxygenators or extra corporeal circuits during surgery. After use the pump is easily detachable from its drive motor to enable a new blood pump to be mounted for the next operation. The pump impeller includes vanes at the base which extend at an angle to the plane of rotation and smoothly merge along a common plane with a plurality of helical fingers respectively. The width of the helical fingers gradually diminishes from the vanes to their extremities which are angularly spaced from each other at the pump inlet. The helical fingers flow the blood helically about the impeller axis to the vanes which then centrifugally flow the blood to the pump outlet tangentially of the pump housing.
