Embodiments of an injector, syringe, syringe interface, and piston/plunger assembly for an injector (of contrast medium, for example) are described. Preferably, the syringe is adapted to engage a syringe interface mechanism such that the syringe may be connected to an injector without regard to any particular orientation of the syringe to the injector or to the piston/plunger assembly.

An adapter for releasably attaching a syringe to an injector includes a first section and a second section connected about a hinge axis that is generally perpendicular to a longitudinal axis of the adapter. The first section and the second section are rotatable about the hinge axis between an open position to allow loading of the syringe into the adapter from a position to the rear of the hinge axis and a closed position to retain the syringe therein. The hinge axis is preferably off-center from the longitudinal axis of the adapter and the adapter further includes a releasable mounting mechanism positioned on a rearward end of the adapter to mount the adapter in a desired position relative to the front wall of the injector.

An adapter includes a syringe carrier adapted to seat at least a portion of the syringe. The syringe carrier includes at least one rearward facing abutmer member to abut at least one forward facing surface on a syringe. The syringe carrie includes an opening therein to allow a drive member of an injector to communicate forward force to the plunger through abutment without connective engagement between the drive member and the plunger. The adapter further includes a releasable mounting mechanism positioned to the rear of the syringe carrier to mount the adapter in a desired position relative to the front wall of the injector. An adapter includes a first section and a second section that are rotatable relative to each other about a hinge axis generally perpendicular to a longitudinal axis of the adapter. An adapter includes a first section and a second section that are generally the same in construction, the first section and the section being connectable to form a syringe carrier to seat at least a portion of the syringe.

A syringe interface or adapter includes a first retaining member that pivots about an axis generally perpendicular to and offset from the axis of an injector piston when the syringe interface is attached to the injector. The first retaining member pivots in a rearward direction to engage a portion of the syringe flange. The syringe interface further includes a second retaining member slideably positioned within a passage in the syringe interface to slide in a direction generally perpendicular to the axis of the piston when the syringe interface is attached to the injector to engage a portion of the syringe flange. The first retaining member and the second retaining member preferably cooperate to engage the syringe flange around the entire perimeter of the syringe flange. The first retaining member is preferably biased toward an open position. The syringe interface can also include a rear portion having an attachment mechanism to attach the syringe interface to the injector.

The fluid delivery system generally includes a source of injection fluid, a pump device a fluid path set disposed between the source of injection fluid and the pump device, and a fluid control device. The fluid path set includes a multi-position valve. The fluid control device is operatively associated with the fluid path set and includes a valve actuator adapted to operate the multi-position valve. The valve actuator is adapted to close the multi-position valve to isolate the pump device from a patient and stop flow of the injection fluid to the patient at substantially any pressure or flow rate generated by the pump device for delivering a sharp bolus of the injection fluid to the patient. The valve actuator is generally adapted to selectively place the pump device in fluid communication with the source of injection fluid for supplying the injection fluid to the pump device and the patient.

The fluid path set is intended for use in a fluid delivery system. The fluid path set includes a multi-patient use section adapted for connection to a syringe used in the fluid delivery system, and to a source of fluid, such as contrast media, to be loaded into the syringe. The fluid path set further includes a per-patient use section that is removably connected to the multi-patient use section. A connector removably connects the multi-patient use section and the per-patient use section. A drip chamber is provided between the source of fluid and the syringe, and includes a projection for determining a level of fluid in the drip chamber. The per-patient use section includes a pressure isolation mechanism. The pressure isolation mechanism includes a lumen, a pressure isolation port, and a valve member with a biasing portion that biases the valve member to a normally open position.
