Patent ID: 7273477

Claim:
A method of attaching a syringe comprising a flange to an injector, the method comprising: providing an injector comprising: a mounting mechanism on a front of the injector; a piston reciprocally movable through the mounting mechanism; and an adapter operable to attach a syringe comprising a flange to the adapter, the adapter comprising: a rear portion comprising an attachment mechanism adapted to attach the adapter to the mounting mechanism of the injector; a first retaining member that pivots about an axis generally perpendicular to and offset from the axis of the piston when the adapter is attached to the injector, the first retaining member pivoting in a rearward direction to engage a portion of the syringe flange; and a second retaining member slideably positioned within a passage in the adapter to slide in a direction generally perpendicular to the axis of the piston when the adapter is attached to the injector to engage a portion of the syringe flange; inserting the syringe flange into the adapter; pivoting the first retaining member about an axis generally perpendicular to and offset from the axis of the injector piston to engage a portion of the syringe flange; and moving the second retaining member in a direction generally perpendicular to an axis of an injector piston to engage at least a portion of the syringe flange.
