Method for making patch-sized fluid delivery systems
First Claim
1. A method for making a delivery device for delivering an infusion medium to a user, the method comprising:
- providing a first housing portion adapted to be secured to a user;
providing a second housing portion configured to be selectively engaged with and disengaged from the first housing portion to allow disposal of the first housing portion without disposing of the second housing portion;
supporting a reservoir on the first housing portion, the reservoir having an interior for containing a fluidic medium;
supporting a pumping chamber on the first housing portion, for containing the fluidic medium for expanding an expandable structure, wherein the expandable structure comprises a bellows structure;
coupling a conduit in fluid flow communication with the pumping chamber and an interior volume of the expandable structure; and
operatively coupling a drive device for selectively conveying the fluidic medium through the conduit, from the pumping chamber to the interior volume of the expandable structure, to selectively expand the expandable structure, when the first housing portion and the second housing portion are engaged.

Abstract
A patch-sized fluid delivery device may include a reusable portion and a disposable portion. The disposable portion may include components that come into contact with the fluid, while the reusable portion may include only components that do not come into contact with the fluid. Redundant systems, such as redundant controllers, power sources, motor actuators, and alarms, may be provided. Alternatively or additionally, certain components can be multi-functional, such a microphones and loudspeakers that may be used for both acoustic volume sensing and for other functions and a coil that may be used as both an inductive coupler for a battery recharger and an antenna for a wireless transceiver. Various types of network interfaces may be provided in order to allow for remote control and monitoring of the device.
