Patent number: 10864335Abstract: A system, apparatus and methods are provided for supplying gases to a user. The supply includes a sub-therapeutic mode and a pressure support mode for delivering therapy to a user. A flow diversion device or valve switches from a first mode corresponding with the sub-therapeutic mode of the system to a second mode corresponding with the pressure support mode of the system. In the first mode, the valve opens a larger flow path between the interior of the user interface and ambient air than in the second mode.Type: GrantFiled: August 23, 2017Date of Patent: December 15, 2020Assignees: Fisher & Paykel Healthcare Limited, New York UniversityInventors: Donald Roy Kuriger, David Cumin, David M.

Publication number: 20190298949Abstract: Apparatus and methods are disclosed for controlling pressure delivery to a user such as a patient. A flow generator generates an outlet flow at an outlet port for delivery to a patient. At least one sensor measures properties of the flow of gas at the outlet port or being delivered to the patient. A controller is operatively connected to the flow generator and the at least one sensor, and is adapted to operate according to a pressure control mode in which the controller controls the flow generator to output a substantially steady pressure or a flow control mode in which the controller controls the flow generator to output a substantially steady flow. The controller operates in the flow control mode when a patient may be awake and in the pressure control mode when the patient may be asleep.Type: ApplicationFiled: February 28, 2019Publication date: October 3, 2019Inventors: Christopher Earl Nightingale, Donald Roy Kuriger
