1. A single-use, portable infusion pump device, comprising:
- a pump housing including an interior wall that at least partially defines a cylindrical cavity configured to slidably receives an outer wall of a pre-filled medicine cartridge insertable through an opening defined by the pump housing;
a non-rechargeable battery fixedly positioned in the pump housing;
a drive system positioned in the pump housing to dispense medicine from the pre-filled medicine cartridge when the pre-filled 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, wherein the drive system nonreversibly advances the piston rod only in a forward longitudinal direction toward the pre-filled medicine cartridge when the pre-filled medicine cartridge is slidably received in the pump housing; and
one or more electrical contacts fixedly positioned along an exterior face of the pump housing such that the electrical contacts are exposed along the exterior of the pump housing and are configured to mate with corresponding electrical contacts of a releasably attachable controller device.
