Abstract
The invention relates to an adapter for a syringe plunger. The adapter of some embodiments may include a first side adapted to interface with a syringe plunger and an opposing a second side adapted to interface with a drive ram of a medical fluid injector. The adapter may include a peripheral side surface exhibiting a thickness and may include what may be characterized as at least one mating section adapted to engage with the syringe plunger. The mating section(s) may include a channel extending through the entire thickness of the adapter. In some embodiments, the mating section(s) may include a stop adjacent the channel that extends less than the entirety of the thickness of the adapter.

47. A method of using a syringe plunger adapter, the method comprising:
-
adapting a syringe plunger so that the associated syringe may be utilized with a desired medical fluid injector, wherein the adapting comprises releasably interconnecting a plunger adapter and the syringe plunger, wherein the releasably interconnecting comprises; contacting the syringe plunger with the plunger adapter; and rotating at least one of the syringe plunger and the plunger adapter relative to another of syringe plunger and plunger adapter during the contacting; contacting a drive ram engaging feature of the plunger adapter with a drive ram of the medical fluid injector once the plunger adapter has been and remains releasably interconnected with the syringe plunger; and moving the syringe plunger rearwardly while the plunger adapter and the syringe plunger are releasably interconnected with one another, wherein the moving comprises pulling the plunger adapter rearward using the drive ram of the medical fluid injector while the drive ram is in contact with the drive ram engaging feature of the plunger adapter. - View Dependent Claims (48, 49, 50, 53, 54, 55, 56, 57)
