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 engagable with the piston regardless of a rotational orientation of the piston relative to the plunger.
