1. An infusion pump system, comprising:
- an infusion pump assembly including a housing and a plunger pusher within the housing; and
a baseplate assembly including a baseplate and a medicament cartridge, including a barrel defining a reservoir and a plunger movable within the barrel, on the baseplate;
wherein the infusion pump assembly and the baseplate assembly are configured to be attached to one another in such a manner that the plunger pusher will be aligned with the plunger and the baseplate can be separated from the infusion pump assembly without removing the plunger pusher from within the housing of the infusion pump assembly; and
wherein the plunger pusher is movable between a retracted position and an extended position where at least a portion of the plunger pusher is located within the medicament cartridge barrel.
