Self-orienting syringe and syringe interface
First Claim
1. A syringe comprising:
- a barrel having a proximal end, a distal end, and a sidewall extending substantially circumferentially between the proximal end and the distal end along a longitudinal axis; and
at least one syringe retaining member having at least one first lug protruding radially outward relative to an outer surface of the sidewall, the at least one first lug comprising a base surface and at least one second surface,wherein the at least one second surface is tapered axially relative to the longitudinal axis of the barrel in a proximal direction,wherein the at least one first lug is configured for engagement with a locking mechanism in a syringe port on a fluid injector, andwherein at least a portion of the at least one second surface axially ejects the syringe from the syringe port upon rotation of the syringe.

Abstract
A syringe includes a barrel having a proximal end, a distal end, and a sidewall extending between the proximal end and the distal end along a longitudinal axis. At least one syringe retaining member protrudes radially outwardly relative to an outer surface of the sidewall. The at least one syringe retaining member tapers axially in a direction from the distal end toward the proximal end. The at least one syringe retaining member is configured for selective engagement with a locking mechanism on a fluid injector to releasably lock the syringe with the fluid injector. A taper of the at least one syringe retaining member is configured to rotationally guide the syringe into alignment with the locking mechanism.

a barrel having a proximal end, a distal end, and a sidewall extending substantially circumferentially between the proximal end and the distal end along a longitudinal axis; and at least one syringe retaining member having at least one first lug protruding radially outward relative to an outer surface of the sidewall, the at least one first lug comprising a base surface, at least one second surface, and a proximal point at a most proximal end of the at least one second surface, wherein the at least one second surface is tapered axially relative to the longitudinal axis of the barrel in a proximal direction ending at the proximal point, wherein the at least one first lug is configured for engagement with a locking mechanism in a syringe port on a fluid injector to releasably lock the syringe with the fluid injector, and wherein the proximal point and at least a portion of the at least one second surface rotationally guide the syringe into self-orienting alignment with the locking mechanism. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31)

32. A syringe comprising:
-
a barrel having a proximal end, a distal end, and a sidewall extending substantially circumferentially between the proximal end and the distal end along a longitudinal axis; and at least one syringe retaining member having at least one first lug protruding radially outward relative to an outer surface of the sidewall, the at least one first lug comprising a base surface, at least one second surface, and a proximal point at a most proximal end of the at least one second surface, wherein the base surface is substantially perpendicular to the longitudinal axis of the barrel and the at least one second surface is tapered axially relative to the longitudinal axis of the barrel in a proximal direction ending at the proximal point, wherein the at least one lug is configured for engagement with a locking mechanism in a syringe port on a fluid injector to releasably lock the syringe with the fluid injector, wherein the proximal point and at least a portion of the at least one second surface rotationally guides the syringe into self-orienting alignment with the locking mechanism, and wherein at least a portion of the at least one second surface axially ejects the syringe from the syringe port upon rotation of the syringe.
