Abstract

A syringe including a syringe body extending from a proximal end to a distal end, and a stabilizing element provided on the distal end of the syringe body, a portion of the stabilizing element extending substantially perpendicular to a longitudinal axis of the syringe body. A multi-use disposable set (MUDS) includes a plurality of syringes, each syringe having a syringe body, a proximal end, a distal end spaced apart from the proximal end along a longitudinal axis of the syringe body, a stabilizing element provided on the distal end, a portion of the stabilizing element extending substantially perpendicular to the longitudinal axis of the syringe body, and a manifold in fluid communication with the distal end of each of the plurality of syringes.

First claim

The invention claimed is:

1. A multi-use disposable set (MUDS) comprising:
a plurality of syringes, each syringe having a syringe body, a proximal end, a distal end spaced apart from the proximal end along a longitudinal axis of the syringe body, a cone portion and a nozzle extending distally from the distal end of the syringe body, and a stabilizing element provided on the distal end, the cone portion being monolithically formed with the syringe body, the stabilizing element comprising a continuous ring that extends around an entire outer circumferential surface of a proximal end of the cone portion on the distal end, the stabilizing element having an engagement surface extending substantially perpendicular to the longitudinal axis of the syringe body, wherein the engagement surface is configured to stabilize a vertical alignment of each syringe of the plurality of syringes when a planar surface of a top plate of a fluid injector system defining at least one syringe slot is moved into a closed position to contact the engagement surface of each of the syringes, wherein an outer diameter of the stabilizing element is greater than an outer diameter of the syringe body, and wherein the stabilizing element is integrally formed on the syringe body;
a frame for receiving at least a portion of the proximal end of each syringe of the plurality of syringes prior to the top plate of the fluid injector system being moved into engagement with the engagement surface of each syringe, and for loading into a bottom guide of the fluid injector to align the MUDS in a receiving space of the fluid injector; and
a manifold in fluid communication with the distal end of each syringe of the plurality of syringes.

2. The MUDS of claim 1 , wherein each engagement surface is configured to provide a stable verticle alignment of the respective syringe with a corresponding movable piston element of the fluid injector system as a planar surface on the top plate of the fluid injector system contacts the stabalizing element.
