Patent ID: 7497843

Claim:
A syringe interface for attaching a first syringe to an injector, the first syringe comprising an elongated main body, a plunger movably disposed within the main body, a first set of generally opposing, radially outward projecting mounting flanges, and a second set of generally opposing, radially outward projecting mounting flanges, the first set of mounting flanges being offset from the second set of mounting flanges, the syringe interface comprising: a first set of generally opposed slots adapted to receive therethrough the first set of mounting flanges; a second set of generally opposed slots adapted to receive therethrough the second set of mounting flanges, the first set of slots being offset from the second set of slots; a first set of generally opposed retaining flanges adapted to releasably engage the first set of mounting flanges; a second set of generally opposed retaining flanges adapted to releasably engage the second set of mounting flanges when the syringe is rotated within the syringe interface to bring the first set of mounting flanges into general alignment with the first set of retaining flanges and the second set of mounting flanges into general alignment with the second set of retaining flanges; and a syringe verification mechanism comprising: at least one extension disposed within at least one slot of the first set of slots and axially forward of the second set of generally opposed retaining flanges; and at least a first flange abutment member in operative connection with the at least one extension, the first flange abutment member being positioned to prevent engagement of the second set of mounting flanges with the second set of retaining flanges unless the at least one extension interacts with at least one of the flanges of the first set of mounting flanges, wherein the first flange abutment member comprises a first contact member slidably disposed in an axial direction within the at least one slot of the first set of slots, wherein the syringe verification mechanism further comprises a second contact member slidably disposed in an axial direction within the other slot of the first set of slots, wherein the first contact member and the second contact member project forward from an annular member that is slidably disposed within the syringe interface.
