ABSTRACT:
An inverted type syringe for use with a vial having a stopper piston closing at one end of the vial. Complementary male and female connectors on the upper end of the hub and the adjacent portion of the piston establish a push or pull connection between the piston and the hub. As the connectors are engaged, the piston is punctured so pressure on the vial causes ejection of the contents.
