Abstract:
A plunger for use in a syringe, the plunger comprising:a releasable connection mechanism adapted to make a releasable connection with an actuating shaft of an injector, the actuating shaft adapted for reciprocal motion to control movement of the plunger, the releasable connection mechanism including: a capture member projecting proximally from the plunger, the capture member adapted to flex radially outwardly when contacted by the actuating shaft to form a releasable engagement with the actuating shaft when the actuating shaft and the capture member are in an engagement position relative to each other, the capture member further adapted to release the actuating shaft upon engagement with a release member of the injector, wherein said release member is a plate defining an aperture through which the actuating shaft passes; and a finger extending radially outwardly from the capture member, the finger adapted to abut against an inner surface of the plate to disengage the capture member from the actuating shaft.
