1. A portable infusion pump system, comprising:
- a pump device including;
a pump housing that defines a cavity extending along a longitudinal axis to receive a pre-filled medicine cartridge, and a drive system at least partially enclosed in the pump housing to dispense a medicine from the pump device when the medicine cartridge is received in the cavity;
a controller device including;
a controller housing releasably matable with the pump housing so as to removably mount the controller device to the pump device, wherein a first electrical connector of the pump device mates with a second electrical connector of the controller device when the controller device removably mounts to the pump device; and
a release member that is movably mounted to one of the pump housing and the controller housing and that is spring biased toward a locking position, the release member being movable away from the other of the pump housing and the controller housing prior to detaching the controller device and the pump device from one another, the release member being movable from the locking position in which the controller device and the pump device are retained together for electrical connection of the first and second electrical connectors to a second position in which the controller device and the pump device are detachable from one another, wherein the release member is spring biased to move to the locking position to engage a mating structure of the other of the pump device and the controller device in response to the controller housing mating with the pump housing.

Abstract
Some embodiments of an infusion pump system include a controller device that is configured to removably attach to a pump device in a manner that provides a secure fitting, an overall compact size, and a reliable electrical connection. In particular embodiments, the controller device can be secured to the pump device in a generally side-by-side arrangement. The compact size can enhance the discreteness and portability of the infusion pump system.

11. A portable infusion pump system, comprising:
-
a pump device including at least a portion of a drive system to dispense a medicine from a prefilled medicine cartridge when the medicine cartridge is slidably inserted into the pump device; a controller device removably mountable to the pump device so that the controller device engages and mates with an exterior of the pump device, the controller device having a user interface display and being in electrical communication with an electrically powered actuator housed inside the pump device when the controller device is removably mounted to the pump device; and a release member that is movably mounted to one of the pump device and the controller device and that is spring biased toward a locking position, the release member being movable from the locking position in which the controller device and the pump device are retained together for electrical connection to a second position in which the controller device and the pump device are detachable from one another, the release member being movable away from the other of the pump device and the controller device prior to detaching the controller device and the pump device from one another, wherein the release member is spring biased to move to the locking position to engage an external mating structure of the other of the pump device and the controller device in response to the controller device engaging and mating with the exterior of the pump device. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A portable infusion pump system, comprising:
-
a pump device including;
a pump housing that defines a cavity extending along a longitudinal axis to receive a pre-filled medicine cartridge, and a drive system at least partially enclosed in the pump housing to dispense, a medicine from the pump device when the medicine cartridge is received in the cavity;a controller device including;
a controller housing releasably matable with the pump housing so as to removably mount the controller device to the pump device, wherein a first electrical connector of the pump device mates with a second electrical connector of the controller device when the controller device removably mounts to the pump device; anda release member that is movably mounted to one of the pump housing and the controller housing and that is spring biased toward a locking position such that the release member is positioned in the locking position when the controller device and the pump device are attached and when the controller device and the pump device are detached, the release member being movable from the locking position in which the controller device and the pump device are retained together for electrical connection of the first and second electrical connectors to a second position in which the controller device and the pump device are detachable from one another, wherein the release member is spring biased to move to the locking position to engage a mating structure of the other of the pump device and the controller device in response to the controller housing mating with the pump housing.
