FLUID TRANSFER DEVICES FOR USE WITH CARTRIDGES

摘要

Fluid transfer devices (30) for use with syringes (10) and cartridges (30) having an open ended tube (22) hermetically sealed by a rubber stopper (27) and a slidable seal (29) at opposite leading and trailing ends, respectively. The fluid transfer devices include a syringe port (34) and a cartridge port for correspondingly slidingly receiving a syringe and a cartridge. The cartridge port preferably includes a primary puncturing member (38) and a secondary puncturing member (39) for correspondingly puncturing a cartridge's rubber stopper offset from its center for fluid transfer purposes between a syringe and a cartridge, and venting purposes. The fluid transfer devices are preferably used with stopping devices for preventing ejection of a cartridge's seal during a filling procedure.
