ABSTRACT:
A syringe barrel assembly includes a plurality of syringe barrels each containing a barrel portion having an open proximal end, a chamber for retaining fluid, and a tip portion extending from a distal end of the barrel portion having a passageway therethrough. The passageway is adapted to accept the hub and second cannula of the hypodermic needle assembly having a hub, a first cannula extending outwardly from a distal end of the hub and a second cannula extending outwardly from a proximal end of the hub wherein the cannulae are in fluid communication. Piercable barrier means is provided in each of said passageways for preventing fluid communication between the chamber and the passageway. A plurality of web portions extending radially outwardly from the tip portions connects the syringe barrel. The web portions are integrally formed from the same material as the syringe barrels. The web portions and the syringe barrels are connected so that the syringe barrels are spaced apart from each other along the substantially straight line wherein the longitudinal axes of the syringe barrel are substantially parallel to each other.
