Self-orienting syringe and syringe interface

摘要

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.

1. A syringe comprising:
a barrel having a distal end, a proximal end, and a sidewall extending substantially circumferentially between the distal end and the proximal end along a longitudinal axis; and at least one engagement member protruding from a terminal portion of the sidewall in a proximal direction along the longitudinal axis, the at least one engagement member tapering axially in a direction from the distal end toward the proximal end, wherein the at least one engagement member is configured for engagement with a locking mechanism of a fluid injector to releasably position the syringe with a syringe port of the fluid injector, and wherein a taper of the at least one engagement member rotationally guides the syringe into self-orienting alignment with the locking mechanism and axially ejects the syringe upon rotation of the syringe.
