Abstract: A syringe includes a barrel having a distal end, a proximal end, and a sidewall extending therebetween along a longitudinal axis. At least one engagement member protrudes from a terminal portion of the sidewall in a proximal direction along the longitudinal axis. The at least one engagement member tapers axially in a direction from the distal end toward the proximal end. The at least one engagement member is configured for engagement with a locking mechanism of a fluid injector to releasably lock the syringe with the fluid injector. A taper of the at least one engagement member is configured to rotationally guide the syringe into alignment with the locking mechanism and axially eject the syringe upon rotation of the syringe. The locking mechanism operatively engages the at least one engagement member regardless of an orientation of the syringe about the longitudinal axis relative to the injector.

Abstract: A pressure jacket for use with a fluid injector includes a barrel having a distal end, a proximal end, and a sidewall extending between the distal end and the proximal end along a longitudinal axis. The pressure jacket includes at least one engagement member protruding from a terminal portion of the proximal end of the barrel in a proximal direction along the longitudinal axis. The at least one engagement member tapers axially in a direction from the distal end toward the proximal end of the barrel. The at least one engagement member engages with a locking mechanism on the fluid injector to releasably lock the pressure jacket with the fluid injector. A taper of the at least one engagement member rotationally guides the barrel into self-alignment with the locking mechanism and axially ejects the barrel upon rotation of the barrel about the longitudinal axis.
