1. A portable infusion pump system, comprising:
- a pump device including;
a pump housing that defines a space to receive a pre-filled medicine cartridge containing a medicine and a drive system to dispense the medicine when received by the pump housing; and
a removable controller device including;
a controller housing that is removably attachable to the pump housing in a fixed relationship by a releasable mechanical connection so that the space to receive the medicine is positioned rearward of the controller housing and 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 rearward position of the space to receive the medicine, the user interface being configured to output information via the display.

-
a pump device including;
a pump housing that defines a space to receive a medicine and a drive system to dispense the medicine when received by the pump housing; anda removable controller device including;
a controller housing that is removably attachable to the pump housing in a fixed relationship so that the space to receive the medicine is positioned rearward of the controller housing and 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 rearward position of the space to receive the medicine, the user interface being configured to output information via the display;wherein the pump housing includes an interior wall that at least partially defines a cylindrical cavity configured to slidably receive an outer wall of a pre-filled medicine cartridge insertable through an opening defined by the pump housing; and 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. - View Dependent Claims (18)

19. A portable infusion pump system, comprising:
-
a pump device including;
a pump housing that defines a space to receive a medicine and a drive system to dispense the medicine when received by the pump housing; anda removable controller device including;
a controller housing that is removably attachable to the pump housing in a fixed relationship so that the space to receive the medicine is positioned rearward of the controller housing and 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 rearward position of the space to receive the medicine, the user interface being configured to output information via the display;wherein the drive system of the pump device comprises a rotational motor that moves a ratchet mechanism, wherein the rotational motor comprises a reversible motor that outputs one or more full rotations in a first direction and in a second opposite direction, and wherein the one or more full rotations of the rotational motor in the first direction causes a pawl member of the ratchet mechanism to partially pivot. - View Dependent Claims (20)
