1. A medical infusion pump system, comprising:
- a pump device including;
a pump housing that defines a space to receive an insulin medication and a drive system to dispense the insulin medication when received by the pump housing; and
a controller device that is releasably mounts with the pump device to electrically connect with at least a portion of the drive system, the controller device including;
a controller housing that is matable with the pump housing so as to form a releasable mechanical connection in which that the space to receive the insulin medication is positioned rearward of a rear face 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 rear face,wherein the user interface is mounted to the controller housing structure that is matable with the pump housing structure so that the user interface is viewable to a user while looking toward the pump device when the releasable mechanical connection is formed.

Abstract
Some embodiments of a medical infusion pump system include a pump device and a removable controller device. When the pump device and the removable controller device are removably attached to one another, the components may provide a portable infusion pump unit to dispense medicine to a user. In particular embodiments, the removable controller device includes a user interface to readily provide information, for example, about the operation of the pump.

14. A medical infusion pump system, comprising:
-
a pump device including;
a pump housing that defines a space to receive an insulin medication and a drive system to dispense the insulin medication when received by the pump housing,wherein the drive system of the pump device comprises a rotational motor that acts upon a ratchet mechanism, wherein one or more full rotations of the rotational motor causes a pawl member of the ratchet mechanism to partially pivot, wherein the rotational motor acts upon the ratchet mechanism to cause an incremental movement of the ratchet mechanism, the incremental movement of the ratchet mechanism driving a piston rod to advance only in a positive longitudinal direction; and a controller device that is releasably mounts with the pump device to electrically connect with at least a portion of the drive system, the controller device including;
a controller housing that is matable with the pump housing so as to form a releasable mechanical connection and a user interface arranged on the controller housing,wherein the user interface is mounted to the controller housing structure that is matable with the pump housing structure so that the user interface is viewable to a user while looking toward the pump device when the releasable mechanical connection is formed. - View Dependent Claims (19, 20, 21, 22, 23)

24. 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 pre-filled insulin medication cartridge extending a majority of the length of the pump housing; a drive system including an electrically powered actuator arranged in the pump housing to dispense the insulin medication when the pre-filled insulin medicine cartridge is slidably received in the pump housing; one or more electrical contacts disposed on the pump housing; and a removable controller device including; a controller housing that is removably attachable to the pump housing in a fixed relationship; 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 so that the controller device electrically communicates with the drive system of the pump device; a user interface coupled to the controller housing, the user interface including a display and one or more user-selectable buttons wherein the pump device and the controller device, when removably attached, provide a portable unit. - View Dependent Claims (25)
