A syringe assembly comprising: a syringe barrel having a first end, a second end, and a sidewall extending between the first end and the second end, the sidewall defining a chamber; a stopper disposed within the chamber of the syringe barrel; a plunger adapter engaged with the stopper, the plunger adapter defining a recessed portion therein; and first and second plunger arms (52, 54) each having a first end (72, 72A) pivotally secured to the plunger adapter and a second end (74, 74A), the first and second plunger arms each having a pre-use position wherein the first and second plunger arms are spaced from each other, and a use position wherein the first and second 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 receiving at least a portion of the first ends of the each one of first and second plunger arms when the first and second plunger arms are in the pre-use position and the use position, characterized in that, the first and second plunger arms (52, 54) are substantially parallel to a longitudinal axis of the syringe barrel when the first and second plunger arms are in the pre-use position and the first plunger arm is positioned on an opposite side of the syringe barrel relative to the second plunger arm when the first and second plunger arms are in the pre-use position and in the use position, the first ends (72, 72A) of the first and second plunger arms are received by the recessed portion providing multiple engagement surfaces thereby stabilizing the first and second plunger arms and the first and second plunger arms are secured to each other. a syringe barrel having a first end, a second end, and a sidewall extending between the first end and the second end, the sidewall defining a chamber; a stopper disposed within the chamber of the syringe barrel; a plunger adapter engaged with the stopper, the plunger adapter defining a recessed portion therein; and first and second plunger arms (52, 54) each having a first end (72, 72A) pivotally secured to the plunger adapter and a second end (74, 74A), the first and second plunger arms each having a pre-use position wherein the first and second plunger arms are spaced from each other, and a use position wherein the first and second 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 receiving at least a portion of the first ends of the each one of first and second plunger arms when the first and second plunger arms are in the pre-use position and the use position, characterized in that, the first and second plunger arms (52, 54) are substantially parallel to a longitudinal axis of the syringe barrel when the first and second plunger arms are in the pre-use position and the first plunger arm is positioned on an opposite side of the syringe barrel relative to the second plunger arm when the first and second plunger arms are in the pre-use position and in the use position, the first ends (72, 72A) of the first and second plunger arms are received by the recessed portion providing multiple engagement surfaces thereby stabilizing the first and second plunger arms and the first and second plunger arms are secured to each other.
