SYRINGE HAVING DUAL PIVOTING ARM PLUNGER ROD

摘要

A syringe assembly (10) includes a syringe barrel (12) having a first end (14) a second end (16) and a sidewall (18) extending between the first end and the second end. The syringe assembly further includes a stopper (58) disposed within a chamber (20) of the syringe barrel a plunger (50) adapter (56) engaged with the stopper and defining a recessed portion therein and first and second plunger arms each having a first end pivotally secured to the plunger adapter. The first and second plunger arms (52 54) each have a pre use position where the plunger arms are spaced from each other and a use position where the plunger arms are positioned adjacent to each other and configured to displace the stopper relative to the syringe barrel. The recessed portion (90) of the plunger adapter receives a portion of a first end of a plunger rod when the first and second plunger arms are in the pre use position and the use position.
