Syringeless CT power injectors (also called pressure injectors) have been developed as a solution to reduce contrast fluid waste. The Joint Commission does not allow the reuse of unused cans from disposable syringes, so the syringeless option allows facilities to use contrast media as efficiently as possible.
A syringeless CT (computed tomography) contrast media injector permits delivery to be made directly from standard contrast media bottles, featuring multi-dosing and programmable automatic saline flush. This higher loading capacity for contrast agent ( up to two contrast bottles or 1000 ml) and a bag of saline at initial setup, enables to perform multiple contrast enhanced CT scans without reloading contrast agent; resulting in increased efficiency and less waste.
