ABSTRACT:
A loading mechanism for a medical injector assembly is disclosed. The loading mechanism according to the present invention includes a dosing sleeve slidingly joining first and second injector housing portions and having tabs at a first end and fixed to one of the first or second housing portions at a second end; and a sleeve retainer fixed to the other of the first or second housing portions and engageable with the tabs of the dosing sleeve at an engagement point to prevent movement of the dosing sleeve once an injector plunger is at a rear portion of an injector fluid chamber, wherein movement of the first housing portion away from the second housing portion moves the plunger in a second direction to load fluid into the fluid chamber and movement of the first housing portion toward the second housing portion moves the plunger in a first direction to remove the fluid from the fluid chamber. The disclosed loading mechanism facilitates filling the assembly with medicament and priming the assembly for use.
