Abstract: A frame for engaging at least two fluid containers includes: a first engagement member configured to secure at least a portion of one of the at least two fluid containers; a second engagement member configured to secure at least a portion of another one of the at least two fluid containers; and a body structure connected to the first engagement member and the second engagement member. The body structure is sized and shaped to index the at least two fluid containers with a powered injector system such that the at least two fluid injectors are held in an orientation and distance relative to each other for insertion into at least two pressure jackets associated with the powered injector system.

Abstract: An injector system for delivering a medical fluid, the injector system including an injector configured to receive at least one syringe, the injector comprising at least one piston for releasably engaging and reciprocally driving a plunger or an end wall of the at least one syringe; and a syringe retaining interface comprising one or more retaining elements configured to engage at least a portion of a distal end portion of the at least one syringe to limit movement of the at least one syringe in a distal direction relative to the injector as the medical fluid is delivered from the reservoir via distal movement of the at least one piston.
