Patch-Sized Fluid Delivery Systems and Methods

摘要

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.

主权项

1. 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 rotatable rotor for rotation, the rotor having at least one pad or roller for movement in an annular path with the rotation of the rotor; providing a conduit having a flexible portion; coupling an interior volume of a reservoir in fluid flow communication with the conduit, the interior volume of the reservoir for containing a fluid; supporting the flexible portion of the conduit on the first housing portion and arranging the flexible portion of the conduit within at least a portion of the annular path of the at least one pad or roller to be engaged at locations along the annular path by the at least one pad or roller when the second housing portion and the first housing portion are engaged, the flexible portion of the conduit being resiliently collapsible at the locations of engagement of the at least one pad or roller to provide a pumping action as the rotor rotates while the first and second housing portions are engaged, the conduit being connectable in fluid flow communication with an injection site; supporting a drive device on the second housing portion; and operatively coupling the drive device to the rotor for selectively rotating the rotor to provide, the pumping action while the first and second housing portions are engaged.
