1. A portable ambulatory, skin securable therapeutic fluid delivery device for a user, the device comprising:
- a disposable part housing accommodating at least a first reservoir containing a first therapeutic fluid and a second reservoir containing a second therapeutic fluid;
a reusable part housing accommodating a first pumping mechanism, a second pumping mechanism and a processor, said disposable part housing being removably coupleable to the reusable part housing, wherein the first pumping mechanism delivers the first therapeutic fluid from the first reservoir and the second pumping mechanism delivers the second fluid from the second reservoir, wherein the first and second pumping mechanisms have one or more shared parts, wherein the one or more shared parts comprise a gear and/or a motor;
a first cannula configured to be in fluid communication with the first reservoir, the first cannula being further configured to penetrate skin of the user to subcutaneously deliver the first therapeutic fluid; and
a second cannula configured to be in fluid communication with the second reservoir, the second cannula being further configured to penetrate the skin of the user to subcutaneously deliver the second therapeutic fluid,wherein upon coupling of the reusable part housing and the disposable part housing the first and second pumping mechanisms are controlled by the processor to deliver concomitantly the first therapeutic fluid from the first reservoir to the first cannula at a first dosing rate and the second therapeutic fluid from the second reservoir to the second cannula at a second dosing rate.

Abstract
Delivery of more than one therapeutic fluid as a means to control symptoms of a health conditions is disclosed. More than one therapeutic fluid may be dispensed from more than one reservoir and delivered to a user'"'"'s body via one or more cannula that penetrate the skin. The therapeutic fluids may be delivered by action of one or more pumping mechanisms that may be controlled by a processor in a portable, ambulatory device. The therapeutic fluids may optionally be insulin and one or more of an amylin analog, pramlintide acetate and an exenatide, and the health condition may optionally be diabetes.
