1. A medical infusion pump system, comprising:
- a pump device including;
a pump housing including an interior wall that at least partially defines a space to slidably receive a prefilled medicine cartridge insertable through an opening defined by the pump housing;
a drive system to dispense medicine from the prefilled medicine cartridge when the prefilled medicine cartridge is slidably received in the pump housing, the drive system including a piston rod that is incrementally movable to apply a dispensing force to the prefilled medicine cartridge, the piston rod being irreversibly movable in a positive longitudinal direction into the space that receives the prefilled medicine cartridge;
one or more electrical contacts disposed on the pump housing, at least a portion of the drive system being in electrical communication with the one or more electrical contacts; and
a removable controller device including;
a controller housing that is removably attachable to the pump housing in a fixed relationship so that the space to slidably receive the prefilled medicine cartridge is positioned rearward of a rear face of the controller housing;
one or more electrical contacts disposed on the controller housing, the electrical contacts of the controller device being engageable with the electrical contacts of the pump device when removably attached;
a user interface arranged on the controller housing such that a display of the user interface is positioned along a front face of the controller housing that is opposite from the rear face, the user interface including the display and one or more user-selectable buttons;
wherein the pump device and the controller device, when removably attached, provide a hand-graspable portable unit.
