Abstract
Abstract Perfusion pump driver apparatus for coupling motive power from a controller console to the rotator of perfusion pump. The coupler has a console adapter to connect the coupler apparatus to the pump control console. A pump receptacle is provided in the coupler to connect the pump to the driver. A power transfer mechanism consisting of a bushing and flexible shaft is provided in the coupler to adapt the control console characteristics to the pump characteristics.
