Patch-sized fluid delivery systems and methods
First Claim
1. Apparatus comprising:
- a housing comprising a reusable portion and a disposable portion wherein;
the disposable portion comprising a substrate having flexible membrane material thereon and incorporating therein a fluid channel, the fluid channel being part of a fluid path in the disposable portion from a reservoir port to a cannula port and comprising a series of regions exposed to the flexible membrane material, at least one of such regions being a valve region; and
the reusable portion comprising a control assembly having a mechanical assembly that interacts mechanically with the regions through the membrane material in such a manner as to achieve pumping of fluid along the fluid path, the mechanical assembly including a valve actuator operating on the valve region.

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.

- 18. A disposable unit for a fluid delivery device, the disposable unit removably engageable with a corresponding reusable unit, the disposable unit including a substrate having flexible membrane material thereon and incorporating therein a fluid channel, the fluid channel being part of a fluid path in the disposable unit from a reservoir port to a cannula port and including a series of regions exposed to the flexible membrane material, at least one of such regions being a valve region, so that an mechanical assembly in the resusable portion can interact mechanically with the regions through the membrane material in such a manner as to achieve pumping of fluid along the fluid path.

20. A reusable unit for a fluid delivery device, the reusable unit removably engageable with a corresponding disposable unit including a substrate having a flexible material thereon and incorporating a fluid channel, the reusable unit including a control assembly having an mechanical assembly that interacts mechanically with regions of the fluid channel in the substrate, including a valve region, through the flexible membrane material in such a manner as to achieve pumping of fluid along a fluid path including the fluid channel.
