Patent number: 11957844Abstract: 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: GrantFiled: April 27, 2023Date of Patent: April 16, 2024Assignee: Fisher & Paykel Healthcare LimitedInventors: Dean Antony Barker, Jack Che-Wei Hsu, Jae Chul Han

Patent number: 11918748Abstract: A respiratory assistance apparatus has a gases inlet configured to receive a supply of gases, a blower unit configured to generate a pressurised gases stream from the supply of gases; a humidification unit configured to heat and humidify the pressurised gases stream; and a gases outlet for the heated and humidified gases stream. A flow path for the gases stream extends through the respiratory device from the gases inlet through the blower unit and humidification unit to the gases outlet. A sensor assembly is provided in the flow path before the humidification unit. The sensor assembly has an ultrasound gas composition sensor system for sensing one or more gas concentrations within the gases stream.Type: GrantFiled: March 15, 2021Date of Patent: March 5, 2024Assignee: Fisher & Paykel Healthcare LimitedInventors: Dean Antony Barker, Mikael Douglas Stewart, Peter Geoffrey Hawkins, Kevin Peter O'Donnell, Russel William Burgess

Publication number: 20240001066Abstract: An apparatus for the supply of humidified gases to a patient is disclosed that comprises a gases supply passage downstream of a humidified gases supply, and upstream of a patient in use, where at least one sensor is embedded in or located on the outside of the wall of the passage. In preferred forms the wall of the passage divides the sensor(s) from a flow of gases in the passage. In use, a controller receives an output of the sensor(s) and derives from the output of the sensor(s) an estimation of a property of gases flowing through the passage or provides a control output to the humidified gases supply according to the output of the sensor(s).Type: ApplicationFiled: July 5, 2023Publication date: January 4, 2024Inventors: Dean Antony Barker, Kevin Peter O'Donnell, Martin Paul Friedrich Kramer, Stanislav Tatkov, Therese Clark

Publication number: 20230381436Abstract: A respiratory flow therapy apparatus including a sensing chamber which measures a flow of gases provided to a patient. The sensing chamber can be located after a blower and/or mixer. The sensing chamber can include an ultrasonic transducer, a temperature sensor, a heated temperature sensing element, and/or a gas concentration sensor. A flow path of gases used in conjunction with the sensor system prevents unwanted vorticity in the flow of gases that can create anomalies in measuring flow.Type: ApplicationFiled: April 21, 2023Publication date: November 30, 2023Inventors: Russel William Burgess, Jess Edward Donnelly, Dean Antony Barker, Philip John Dickinson, Andre Van Schalkwyk, Joel Michael Lawson

Publication number: 20220184329Abstract: 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: ApplicationFiled: November 29, 2021Publication date: June 16, 2022Inventors: Russel William Burgess, Dean Antony Barker, Kevin Peter O'Donnell

Publication number: 20220096772Abstract: 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: ApplicationFiled: October 18, 2021Publication date: March 31, 2022Inventors: Kevin Peter O'Donnell, Robert Stuart Kirton, Sean Joel Babbage, Dean Antony Barker, Stanislav Tatkov
