Publication number: 20230131400Abstract: The operational parameters of a respiratory apparatus can be controlled through the use of a user interface located on a separate or separable mobile computing device. Sensors or features located on the mobile computing apparatus can be used to adjust the operation parameters or therapy of the respiratory apparatus or otherwise improve the compliance of a patient utilizing the respiratory apparatus.Type: ApplicationFiled: October 18, 2022Publication date: April 27, 2023Inventors: Guohua BAO, Venkata Subbarao POTHARAJU, Arjen David KAT, Gavin Andrew Bryson RYAN, Ian Patrick Sarsfield HICKEY, Benjamin Wilson CASSE, Sujeewa WANNIGAMA, Gregory Martyn SMITH, Nordyn ALAMI, Nimansha BUDHIRAJA, Donald Roy KURIGER, Adam John DARBY, Bernhard Florian LAMPRECHT, Jeremy Livingston MILLER, Johannes Nicolaas BOTHMA, Dean Antony BARKER, Quinton Michael SMITH, Emma Louise NASIMI, Andrew Jun LI, Nicholas Edward VAUGHAN, Zarin KASAD

Patent number: 11617846Abstract: A multi-night titration (MNT) process to find an optimal single therapeutic pressure of a CPAP device. This single therapeutic pressure can then be used on an on-going basis by the patient after the titration period. The MNT process differs from current auto adjusting processes used for titration (or ongoing use) in that the MNT process does not respond locally by adjusting pressures to individual events. With existing devices, the continuous adjustment of supplied air pressure always responds to one or a small number of events and thus fails to compensate for a patient's adaptation thereto, resulting in the supply of a less than optimal therapeutic pressure to the patient. While auto adjusting processes often capture and respond well to short-term and transient conditions, the MNT process of the current disclosure seeks to capture long term trends and find the most suitable average single pressure for a patient.Type: GrantFiled: April 16, 2020Date of Patent: April 4, 2023Assignees: FISHER & PAYKEL HEALTHCARE LIMITED, NEW YORK UNIVERSITYInventors: David M. Rapoport, Indu Ayappa, Simei Gomes Wysoski, Sujeewa Wannigama, David Robin Whiting

Patent number: 11517689Abstract: The operational parameters of a respiratory apparatus can be controlled through the use of a user interface located on a separate or separable mobile computing device. Sensors or features located on the mobile computing apparatus can be used to adjust the operation parameters or therapy of the respiratory apparatus or otherwise improve the compliance of a patient utilizing the respiratory apparatus.Type: GrantFiled: August 5, 2014Date of Patent: December 6, 2022Assignee: Fisher & Paykel Healthcare LimitedInventors: Guohua Bao, Venkata Subbarao Potharaju, Arjen David Kat, Gavin Andrew Bryson Ryan, Ian Patrick Sarsfield Hickey, Benjamin Wilson Casse, Sujeewa Wannigama, Gregory Martyn Smith, Nordyn Alami, Nimansha Budhiraja, Donald Roy Kuriger, Adam John Darby, Bernhard Florian Lamprecht, Jeremy Livingston Miller, Johannes Nicolaas Bothma, Dean Antony Barker, Quinton Michael Smith, Emma Louise Nasimi, Andrew Jun Li, Nicholas Edward Vaughan, Zarin Kasad

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. Rapoport, Christopher Earl Nightingale, Sujeewa Wannigama, Mark John Arrowsmith, Vitaly Kapelevich
