Patent number: 11213643Abstract: Systems and method for conducting respiratory therapy in a respiratory system can adjust a flow of respiratory gases to a patient based upon a detected patient breath cycle. The respiratory system can include a non-sealed patient interface. The respiratory system can be configured to deliver a high flow therapy. A patient breath cycle may be determined using one or more measured parameters, such as a flow rate, a blower motor speed, and/or a system pressure. A flow source may be adjusted to have a phase matching that of the patient's breath cycle, such that flow in increased in response to the patient inhaling, and decreased in response to the patient exhaling.Type: GrantFiled: May 17, 2017Date of Patent: January 4, 2022Assignee: Fisher & Paykel Healthcare LimitedInventors: Russel William Burgess, Dean Antony Barker, Kevin Peter O'Donnell

Patent number: 11185653Abstract: A respiratory mask or other sealing interface can be used in combination with a nasal cannula or other unsealing interface in providing respiratory therapies for the treatment of COPD or OSA. The mask can act as a pressure vessel over the top of a nasal cannula, with the intention of increasing expiratory pressure whilst allowing the nasal cannula to provide a user with breathing gases of a high humidity and temperature. The ability to selectively apply increased expiratory pressure may be effective in reducing a user's breathing rate and thus beneficial in the treatment of respiratory distress.Type: GrantFiled: March 27, 2015Date of Patent: November 30, 2021Assignee: Fisher & Paykel Healthcare LimitedInventors: Kevin Peter O'Donnell, Robert Stuart Kirton, Sean Joel Babbage, Dean Antony Barker, Stanislov Tatkov

Publication number: 20210353895Abstract: The disclosure relates to medical tubes and methods of manufacturing medical tubes. The tube may be a composite structure made of two or more distinct components that are spirally wound to form an elongate tube. For example, one of the components may be a spirally wound elongate hollow body, and the other component may be an elongate structural component also spirally wound between turns of the spirally wound hollow body The tube need not be made from distinct components, however. For instance, an elongate hollow body formed (e.g., extruded) from a single material may be spirally wound to form an elongate tube. The elongate hollow body itself may in transverse cross-section have a thin wall portion and a relatively thicker or more rigid reinforcement portion. The tubes can be incorporated into a variety of medical circuits or may be employed for other medical uses.Type: ApplicationFiled: April 21, 2021Publication date: November 18, 2021Inventors: Christopher Jaye Norman AMADIO, Elmo Benson STOKS, Charles Christopher NORTH, Mahran Maumoon SUJAU, Joshua Daniel STROOBANT, Gavin Walsh MILLAR, Matthew Liam BUSWELL, Ibrahim AL-TIAY, David Leon MCCAULEY, Andre VAN SCHALKWYK, Katja MUNKELT, Matthew Robert WILSON, Helgard OOSTHUYSEN, Sanjay Parag PATEL, Dominique Richard D'ANDREA, Grant Martin DOVER, Dean Antony BARKER, Jonathan David HARWOOD

Publication number: 20200129725Abstract: The present invention provides for an improved method of determining a water out condition in a humidified gases supply apparatus. The method includes a two step process including a primary determination of a water out condition and a secondary determination of a water out condition. This primary determination is made during observation of the normal operation of the apparatus. During the secondary determination the method takes temporary control over the humidifying part of the apparatus. The secondary determination confirms or contradicts the primary determination.Type: ApplicationFiled: December 5, 2019Publication date: April 30, 2020Inventors: Dean Antony Barker, Jack Che-Wei Hsu, Jae Chul Han
