Abstract of the Disclosure The pump for delivering blood has a torus-shaped deformable bag disposed coaxially about a central section within the pump housing. An annular thruster is also provided coaxially of the central section and engages the bag. An electric motor within the housing drives a threaded spindle which in turn drives a nut connected with the thruster via radial spokes in order to move the thruster against the bag to deform the bag in order to exhaust blood therefrom. In another embodiment, a pair of torus-shaped deformable bags are provided within the pump housing on opposite sides of the thruster. Both bags may be used for pumping blood or one bag may be used to form a work store of gas.
