1. A multi-fluid injector system, comprising:
a powered fluid injector comprising a housing enclosing at least one reciprocally operable piston element;
a multi-use disposable set (MUDS) connectable to the powered fluid injector, the MUDS comprising:
at least one syringe having a proximal end and a distal end spaced apart from the proximal end along a longitudinal axis, and a plunger reciprocally movable by the at least one reciprocally operable piston element within a syringe interior of the at least one syringe between the proximal end and the distal end;
a manifold in fluid communication with the distal end of the at least one syringe;
at least one valve in fluid communication with the syringe interior, the at least one valve operable between a filling position for filling the syringe interior with a fluid and a delivery position for delivering the fluid from the syringe interior; and
at least one connection port in fluid communication with the manifold and the syringe interior when the at least one valve is in the delivery position; and
a coupling mechanism for operating the at least one valve between the filling position and the delivery position, wherein the coupling mechanism comprises a blade,
wherein the at least one valve has a slot shaped to receive the blade of the coupling mechanism,
wherein the coupling mechanism self-aligns with the at least one valve to receive the blade of the coupling mechanism within the slot of the at least one valve and wherein the coupling mechanism is spring-loaded to maintain contact with the at least one valve as the blade of the coupling mechanism rotates into alignment with the slot of the at least one valve.
