    Abstract: A pressure jacket configured for connecting to an injector head of a fluid injector has an open distal end, an open proximal end, and a sidewall defining a throughbore extending between the distal end and the proximal end along a longitudinal axis. The throughbore is configured for receiving at least a portion of a syringe. The pressure jacket has at least one syringe retaining element positioned at least partially within the throughbore. The at least one syringe retaining element is configured for engaging at least a portion of the syringe during pressurized delivery of fluid from the syringe to prevent or limit a distal movement of the syringe relative to the pressure jacket.

    Abstract: A fluid mixing device for mixing a first injection fluid and a second injection fluid includes a first fluid inlet, a second fluid inlet, a mixing chamber in fluid communication with the first and second fluid inlets, and an outlet port in fluid communication with the mixing chamber. The first fluid inlet is configured to conduct the first injection fluid in a first direction and has a first redirecting surface. The second fluid inlet is configured to conduct the second injection fluid in a second direction along a different axis from the first direction and has a second redirecting surface. The mixing chamber is configured to mix the first injection fluid and the second fluid together. The mixture of the first injection fluid and the second injection fluid exits the fluid mixing device via the outlet port.

    Abstract: An engagement mechanism associated with a reciprocally movable piston of a fluid injector is configured for releasably engaging an engagement portion at a proximal end of a rolling diaphragm syringe having a flexible sidewall configured for rolling upon itself when acted upon by the piston. The engagement mechanism has a plurality of engagement elements reversibly and pivotally movable about a pivot pin relative to the engagement portion of the syringe between a first position, where the plurality of engagement elements are disengaged from the engagement portion of the syringe, and a second position, where the plurality of engagement elements are pivotally movable about the pivot pin in a radially inward direction to engage with the engagement portion of the syringe. The engagement mechanism further has a drive mechanism for moving the plurality of engagement elements between the first position and the second position.

    Abstract: A valve assembly for a fluid injector system includes a valve housing, a first port configured for fluid communication with a fluid injector, a second port, a third port, and a fourth port configured for fluid communication with a patient line. The valve assembly includes an air detection region associated with the first port, a fluid path length having a proximal end in fluid communication with the second port and a distal end in fluid communication with the third port, and a valve element defining a first fluid path and a second fluid path. The first fluid path provides fluid communication between the first and second ports in a delivery position of the valve housing. The second fluid path provides fluid communication between the third and fourth ports in the delivery position. The third port is isolated from the fourth port in a stop position of the valve housing.

    Abstract: A plunger for use with a syringe has a plunger body with a proximal end, a distal end, and a circumferential sidewall extending between the proximal end and the distal end along a plunger longitudinal axis. The plunger further has at least one resiliently deflectable retaining member having a first segment attached to the plunger body and a second segment protruding toward the distal end of the plunger body and deflectable relative to the first segment. The plunger further has at least one actuation member associated with the at least one resiliently deflectable retaining member. The at least one actuation member interacts with a piston to deflect the at least one resiliently deflectable retaining member upon rotation of the plunger relative to the piston. The plunger is engageable with the piston regardless of a rotational orientation of the piston relative to the plunger.
