Abstract

A syringe adapter, which permits use of syringes of various types and sizes to be used with a front-loading injector, includes a piston extension and an adapter face plate. The piston extension includes structure for connecting the piston extension to a drive piston of the injector and a plunger of the syringe. The adapter face plate includes a mounting device for attaching the adapter face plate to an injector and a recess for receiving the distal flange of the syringe. The adapter face plate may also include locking pivot arms for releasably engaging the syringe flange.

Claims

1. An adapter for connecting a syringe comprising a plunger to an injector comprising a drive piston, the adapter comprising:

a piston extension having a first end and a second end, the first end comprising a first connector member adapted to be connected to the drive piston and a second end comprising a second connector member adapted to be connected to the plunger of the syringe.

2. The adapter of claim 1 wherein the second connector member comprises threads mateable with threads formed on the plunger of the syringe.

3. The adapter of claim 2 wherein the threads on the second connector members are external threads.

4. The adapter of claim 1 wherein the first connector member comprises a protrusion mateable with a slot formed in the drive piston.

5. The adapter of claim 1 wherein the first connector member defines a slot mateable with an attachment flange formed on the drive piston.
