SYRINGE, INJECTOR AND INJECTOR SYSTEM

摘要

The present invention provides a syringe and a powered injector for use therewith in which the syringe is attachable to a powered drive member of an injector over a range of relative axial positions of the syringe plunger and the drive member. The syringe comprises a plunger, and a plunger extension connected thereto and extending rearward from the plunger, such that the syringe may be operated manually or by a powered injector. By providing a plurality of cooperating attachment members over a range of axial positions on at least one of the plunger extension or the powered drive member, operative attachment of the plunger and the drive member is made possible at multiple axial positions of the plunger (within the syringe) for each axial position of the drive member over at least a range of possible plunger axial positions. Attachment of the plunger to the drive member at various axial positions of the plunger thus becomes an easier task than previously possible with current powered injector systems.
