Abstract
A syringe assembly includes a syringe barrel having a first end, a second end, and a sidewall extending between the first end and the second end. The syringe assembly further includes a stopper disposed within a chamber of the syringe barrel, a plunger adapter 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 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 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.
