Abstract
Embodiments including an injection device having a housing with an outer surface, an inner surface, a proximal end and a distal end, and a defining a chamber extending between the proximal end and the distal end are provided herein. The device may include a plunger having a first end and a second end, the plunger being movable proximally and distally within the chamber of the housing, the plunger comprising a plunger rod extending from the first end to the second end of the plunger; and a plunger limiting mechanism configured to interface with the plunger rod, to limit the proximal movement of the plunger and prevent removal of the plunger from the housing.
