Abstract
A plunger rod is for use with a syringe having a syringe barrel. The plunger includes an elongated body having a proximal end, a distal end opposite the proximal end, a central axis extending between the proximal end and the distal end, a first curved end face, a second curved end face, and a joining portion joining the first curved end face to the second curved end face. Each of the first curved end face, the second curved end face, and the joining portion extends between the proximal end and the distal end. The first curved end face and the second curved end face together are comprised in the circle defined by an outer perimeter of the elongated body.
