Abstract
A syringe assembly having a collapsible or pivotable plunger rod with magnification properties is provided. In a pre-use or packaged state, the plunger rod is positioned substantially parallel to a barrel of the syringe assembly resulting in the syringe assembly having a reduced length and a smaller packaging footprint. The smaller packaging footprint allows for reduced storage space of the syringe assembly. Upon removal from a packaging and/or a storage space, the plunger rod can be slid or pivoted toward a proximal end of the syringe barrel and locked into place such that the syringe assembly is ready for use. The plunger rod can be shaped to provide magnification to indicia of the syringe barrel and/or contents. Alternatively, a separate magnification member can be associated with the plunger rod and/or secured about the syringe barrel.
