Front-loading syringe adapter for front-loading medical injector
First Claim
1. A syringe adapter apparatus for an injector comprising a drive piston and an injector face plate mounted thereon and defining an opening therein through which the drive piston is extendable, the syringe adapter apparatus comprising, in combination:
- an adapter face plate comprising a mounting device for attaching the adapter face plate to one of the injector face plate and the injector after the injector face plate is removed therefrom, and an attachment mechanism for allowing a syringe to be removably mounted on the adapter face plate, the attachment mechanism comprising a base for receiving the syringe, a pair of pivoting arms attached to the base and movable from an opened position to a closed position to engage the syringe, and a locking member extending from the base to secure the pair of pivoting arms in the closed position after the syringe is received by the base, the adapter face place defining an adapter opening therein through which the drive piston is extendable to connect to a plunger of the syringe; and
a piston adapter attachable to the drive piston for mating engagement with the plunger of the syringe.
