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.

179. A delivery device comprising:
-
a first housing portion; a second housing portion configured to selectively engage with and disengage from the first housing portion; a compressible reservoir located in the first housing portion, the reservoir having an interior volume for containing a fluid, the reservoir having an outlet connectable in fluid flow communication with an injection site, the interior volume of the reservoir being compressible to reduce the interior volume and increase fluid pressure within the interior volume to drive fluid from the interior volume to the injection site; a compression mechanism operable on the reservoir; a drive device supported by the second housing portion and operatively connectable to at least one of the reservoir and the compression mechanism when the first and second housing portions are engaged, to selectively cause relative movement between the reservoir and compression mechanism for selective compression of the reservoir. - View Dependent Claims (180, 181, 182, 183, 184, 185, 186, 187, 188)

189. A method of making a delivery device, the method comprising:
-
providing a first housing portion; providing a second housing portion configured to selectively engage with and disengage from the first housing portion; supporting a compressible reservoir on the first housing portion, the reservoir having an interior volume for containing a fluid and an outlet connectable in fluid flow communication with an injection site, the reservoir being compressible to reduce the interior volume and increase fluid pressure within the interior volume to drive fluid from the interior volume to the injection site; supporting a compression mechanism in a position to selectively compress the reservoir; supporting a drive device supported on the second housing portion in a position to operatively connect to at least one of the reservoir and the compression mechanism when the first and second housing portions are engaged, to selectively cause relative movement between the reservoir and compression mechanism for selective compression of the reservoir. - View Dependent Claims (190, 191, 192, 193, 194, 195, 196, 197, 198)
