Abstract: A syringe adapter includes an adapter body having a first connecting portion that may be received into a power injector unit used to deliver contrast media. The adapter also includes a second connecting portion configured to receive the rearward end of an associated syringe. The adapter includes means for encoding information about the associated syringe that may be communicated to the power injector unit through one or more sensors. The means for encoding information may include a mechanism that moves linearly laterally back and forth to activate an actuator used to convey the encoded information. In particular, the action of installing the adapter may be decoupled from the action of encoding information.

Abstract: A molded heavy-duty ergonomic handle comprises: a top portion, the top portion extending in a longitudinal direction and being substantially smooth; and at least one U-shaped side channel having a plurality of ribs therein, the at least one channel having substantially smooth exterior surfaces and being located on a longitudinal side of the top portion.

Abstract: A syringe adapter assembly comprises an adapter body and a ram extender. In one embodiment, the adapter body (12) is attached to an injector by a rear connector plate (50). In a second aspect, the adapter body (12, 122) may comprise a drain hole (130) and/or seating ring (140). In another aspect, the invention comprises a cleaning member (200) having a body (204) and a plurality of cleaning members (210, 220, 230) extending therefrom.

Abstract: A syringe plunger/jacket assembly may comprise a flexible jacket attached to a rigid plunger. The jacket may comprise at least two sealing rings (front and rear) that prevent fluid from leaking out of the rear of the barrel during injection of fluid from the syringe. The rear sealing ring may not contact or seal the interior surface of the syringe barrel in an unloaded state. In the loaded state, when force is applied in the direction of the forward discharge end of the syringe, pressure is created on the jacket. This condition causes the rear seal to expand and contact and/or seal the interior surface of the syringe barrel.
