Claim:
1. A multiple dose injection device comprising: a fluid conduit; a barrel having a bore, a distal end, and a proximal end wherein the fluid conduit is located at the distal end of the barrel, in fluid communication with the bore and the proximal end of the barrel is adapted to receive a stopper; a plunger having a distal end and a proximal end and a longitudinal axis wherein the stopper is connected to the distal end of the plunger and movable within the barrel, and the plunger has at least one continuous track formed between the distal and proximal ends of the plunger wherein the at least one continuous track further comprises at least one of each of the following: a first rest position, a stop position, having a proximal abutment, a second rest position, a slider having a follower movable substantially perpendicular to the axis of the plunger, the slider having a user-pressable portion; wherein when a portion of the plunger is depressed by a user, the follower moves with respect to the plunger along the camming portion of the at least one continuous track, thereby causing radial motion of the follower and movement of the follower to the stop position at which position a plunger distal movement is prevented by contact of the follower to the proximal abutment, wherein the user may apply a biasing force to the user-pressable portion of the slider, thereby moving the follower along the reset portion to the second rest position and wherein when the follower is within the starting portion of the at least one continuous track, the follower is subject to guidance of the at least one continuous track.
