Abstract
Systems and methods are presented for the visual indication of whether a power injector has discharged fluid from a power injector syringe in a previous medical procedure. In this regard, the systems and methods generally provide for a power injector and a syringe for use with the power injector. The syringe includes a visual indicator (164) that moves between a first state and a second state at approximately the same time that the power injector discharges fluid from the syringe such that an operator may view the change in state.
