A plunger for use with a syringe includes a plunger body defining a central longitudinal axis and having a proximal end, a distal end, and a circumferential sidewall connecting the proximal end and the distal end. The plunger further includes at least one retaining member associated with and extending proximally from the plunger body. The at least one retaining member has a first end connected to the plunger body, a second end proximal to the first end and radially and resiliently deflectable relative to the first end, and at least one catch on the second end. A fluid injector system includes a piston having a plunger engagement mechanism configured for interacting with the at least one retaining element of the plunger to releasably engage the plunger for reciprocally driving the plunger within a barrel of the syringe.

System and method for syringe plunger engagement with an injector

An assembly for retaining a pressure jacket () and a syringe () on a fluid injector, the assembly including a base plate () comprising a body (); at least a first retaining arm () and a second retaining arm () operatively mounted on the body of the base plate, the first retaining arm having a first retaining surface at a distal end thereof and the second retaining arm having a second retaining surface at a distal end thereof, wherein the first retaining surface and the second retaining surface are configured for abutting a distal surface of at least one of the pressure jacket and the syringe; a linkage assembly operatively connected to at least one of the first retaining arm and the second retaining arm, wherein the linkage assembly is configured to move at least one of the first retaining arm and the second retaining arm between at least a first open position and a closed position.
