1. A delivery device for delivering an infusion media to a user, the device comprising:
- a disposable housing portion having a base and adapted to be secured to a user;
a durable housing portion configured to be selectively engaged with and disengaged from the disposable housing portion to allow disposal of the disposable housing portion without disposing of the durable housing portion;
a reservoir for containing infusion media;
a moveable platform on the disposable housing portion and supported for movement relative to the disposable housing portion along a path of motion toward the base of the disposable housing portion, the moveable platform supporting the reservoir for movement with the moveable platform and along the same path of motion of the moveable platform toward the base of the disposable housing portion;
electrical control circuitry contained in the durable housing portion, wherein the electrical control circuitry controls the delivery of infusion media from the reservoir to the user.

Abstract
An infusion media delivery device includes a durable housing portion and a separable disposable portion that selectively engage and disengage from each other. The disposable housing portion secures to the patient and may be disposed of after it has been in use for a prescribed period. The disposable housing portion supports an infusion media reservoir and a needle on a moveable platform. The platform is moveable between a first position in which a needle is disengaged with a patient and a second position in which the needle is engaged with the patient.
