1. A multi-use disposable set (MUDS) comprising:

  • a plurality of syringes, each syringe having a proximal end and a distal end spaced apart from the proximal end along a longitudinal axis, a filling port and a discharge outlet at the distal end of each of the plurality of syringes, and a plunger reciprocally movable within a syringe interior of each of the plurality of syringes between the proximal end and the distal end;

    a manifold in selectable fluid communication with the discharge outlet of each of the plurality of syringes;

    at least one rotatable valve in fluid communication with the distal end of at least one of the plurality of syringes, wherein the at least one rotatable valve comprises a valve head with a slot recessed into the valve head, wherein the slot has a lip at one end of the slot which limits an orientation of a blade of a coupling mechanism of a fluid injector to a single self-aligned orientation, wherein the at least one rotatable valve is rotatably operable between a filling position for filling the syringe interior of the at least one of the plurality of syringes through the filling port and a delivery position for delivering fluid from the syringe interior of the at least one of the plurality of syringes to the manifold through the discharge outlet; and

    at least one connection port in fluid communication with the manifold when the at least one rotatable valve is in the delivery position,wherein the filling port is in fluid isolation from the syringe interior when the at least one rotatable valve is in the delivery position.
