ABSTRACT:
A syringe filling and metering device (2, 90) for pharmaceutical containers (4) including a variable volume region housing the liquid pharmaceutical (78) and a needle access portion, such as a septum (74) or piston (104), which is pierced by the needle cannula (72) of the syringe (6), such as by mounting the syringe in a syringe carrier (8). An elongate piston stop (58) is held in place by a piston driver (42) to which the syringe carrier is threadably connected. The syringe carrier is screwed into the piston driver to drive the barrel of the cartridge over the piston, thus forcing the contents of the cartridge through the needle cannula and into the syringe. The invention can also be practiced with the needle cannula piercing the piston so that the movement of the piston into the barrel of the container forces the liquid pharmaceutical through the needle cannula and into the syringe.
