Abstract: A syringe assembly is provided which includes a hollow barrel that has an interior wall. The interior wall defines a chamber that retains medication. The hollow barrel also includes a distal end and a proximal end. The distal end of the hollow barrel has a passageway that is in contact with the chamber. The proximal end of the hollow barrel has an aperture. The syringe assembly also includes a primary plunger tip that is slidably positioned, in fluid tight engagement, with the interior wall. The primary plunger tip has a receptor to engage an engager of an elongated tip plunger rod. The syringe assembly also includes a secondary plunger tip that is slidably positioned, in fluid tight engagement, with the interior wall. The secondary plunger tip also has a receptor to engage an engager of a tip plunger rod. The secondary plunger tip is disposed between the primary plunger tip and the proximal end of the hollow barrel.
