Patent ID: RE42804

Claim:
An adapter for releasably attaching a syringe to an injector, wherein the syringe comprises a body, a cone region attached to a forward end of the body and a plunger slideably positioned within the body, and wherein the injector comprises a front wall, an opening formed in the front wall, and a drive member reciprocally mounted in the injector, the adapter comprising: a mounting mechanism positioned at a rear of the adapter to mount the adapter in a desired position relative to the front wall of the injector; and a syringe carrier section associated with the mounting mechanism and adapted to seat at least a portion of the syringe, the syringe carrier section defining an opening along a top length thereof to allow placement of the syringe therein from the top, a forward portion of the syringe carrier section comprising two substantially opposed, linear shoulder portions each having first and second ends, the first ends of the shoulder portions being connected by a substantially arcuate member and the second ends of the shoulder portions cooperating to define an opening therebetween, the opposed shoulder portions abutting the cone region of the syringe so that the force exerted by the syringe on the adapter during an injection is generally symmetrical about an axis of the adapter, thereby reducing any bending moment about the mounting mechanism, the syringe carrier section further comprising a rear section defining an opening therein to allow the drive member of the injector to provide forward force to the plunger.
