An injector system for injecting fluid includes a syringe and an injector. The syringe includes a body and a plunger movably disposed within the body. The plunger has at least one flexible leg extending toward the rearward end of the body. The injector has a housing with a front plate, a drive member at least partially disposed within the housing and operable to engage the plunger, and a syringe release assembly operable to release the syringe. The syringe assembly includes a syringe release gear that forms an enclosure for receiving the syringe when the syringe is fully seated within the housing and a plunger release tube surrounding at least a portion of the drive member. The plunger release tube has a first end rotationally engaged with the syringe release gear. Rotation of the syringe release assembly releases the at least one flexible leg from the drive member.

System for syringe engagement to an injector

Syringe assemblies and adapters for syringes that attach to and allow non-native syringes to be accepted by injectors having injector syringe interfaces adapted for particular types of syringes are described herein. Methods of forming the syringe assemblies, and kits including the syringe adapters which enable a non-native syringe to be operably attached to an injector are also described.

Syringe assemblies, methods of forming syringe assemblies and adapters for forming syringe assemblies

A syringe interface is provided for attaching a syringe to an injector. The syringe includes, a first and second set of generally opposing, radially outward projecting mounting flanges, and a second set of flanges offset from the first set of mounting flanges. The syringe interface includes a first set of generally opposed slots adapted to receive therethrough the first set and second set, respectively, of mounting flanges, and a first and second set of generally opposed retaining flanges adapted to releasably engage the first and second set respectively, a set of mounting flanges, when the syringe is rotated within the syringe interface. The syringe verification mechanism includes at least one flange interaction element disposed within at least one slot of the first set of slots, and at least a 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 flange verification element interacts with at least one of the flanges of the first set of mounting flanges.
