Injector systems and syringe adapters for use therewith
First Claim
1. An adapter for releasably attaching a syringe to an injector, wherein the syringe comprises a body having a forward end and a rearward end, 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 syringe carrier adapted to seat at least a portion of the syringe, the syringe carrier comprising a front end, a rear end and at least one rearward facing abutment member operable to abut at least a portion of a forward facing surface associated with the syringe, the syringe carrier defining an opening therein to allow the drive member of the injector to engage the plunger;
a releasable mounting mechanism associated with the syringe carrier to mount the adapter in a desired position relative to the front wall of the injector;
at least one syringe retaining mechanism for retaining the syringe within the syringe carrier; and
a sealing flange positioned forward of the releasable mounting mechanism to abut the front wall of the injector.

Abstract
An adapter includes a syringe carrier adapted to seat at least a portion of the syringe. The syringe carrier includes at least one rearward facing abutment member to abut at least one forward facing surface on a syringe. The syringe carrier includes an opening therein to allow a drive member of an injector to communicate forward force to the plunger through abutment without connective engagement between the drive member and the plunger. The adapter further includes a releasable mounting mechanism positioned to the rear of the syringe carrier to mount the adapter in a desired position relative to the front wall of the injector.
