Beschreibung
Zusammenfassung:	A syringe plunger rod includes a rod body having a proximal rod end and a distal rod end, where the distal rod end has a distal rod end circumference. The syringe plunger rod also includes a threaded extension extending distally from the distal rod end. The threaded extension includes at least one male thread extending from a thread shank, where the thread shank has a proximal thread shank end and a distal thread shank end. The proximal thread shank end has a diameter less than the diameter of the distal rod end circumference. The syringe plunger rod also includes an annular distal rod surface extending between the distal rod end circumference and the proximal male thread shank end.
