Patent number: 12121668Abstract: In some embodiments, a humidification system includes a heater base having a heater plate, a humidification chamber, and circuit. The circuit can include various conduits, including an inspiratory conduit, expiratory conduit, Y-piece, patient conduit, and/or dry conduit. In use, the chamber contains a quantity of liquid. The heater base heats the heater plate, which in turn heats the liquid to a temperature that causes at least some of the liquid to become vapor, thereby humidifying the gases within the chamber. The gas is delivered to the patient via the inspiratory conduit. Various features can help control the system and ensure the patient receives gases having the desired conditions. These features can be used individually or in various combinations and subcombinations both in existing humidification systems and improved systems for respiratory humidification, laparoscopy, and other purposes.Type: GrantFiled: September 11, 2019Date of Patent: October 22, 2024Assignee: Fisher & Paykel Healthcare LimitedInventors: Dexter Chi Lun Cheung, Matthew Jon Payton, Michael Barraclough, Michael John Andresen, Kieran Michael Orchard, Philip James Edgeworth, Peter Kenneth Graham, Anthony James Newland, Daniel John Smith, Timothy James Beresford Sharp, Elmo Benson Stoks, Jonathan Mark Church, Andre van Schalkwyk

Publication number: 20240277966Abstract: Embodiments of a respiratory support apparatus are disclosed comprising features configured to minimize, reduce or contain aerosols carrying pathogens that can cause diseases such as COVID 19, SARS, MERS, Tuberculosis, or any other infectious diseases. Embodiments of a respiratory support apparatus are also provided configured to at least reduce the amount of oxygen required, during use of the apparatus, from an external oxygen supply such as an oxygen tank or hospital wall supply. Embodiments of such apparatus are provided with means to recirculate expiratory gases, and/or redirect leak flow. Embodiments of such apparatus are provided in which expiratory gases are sucked away from the patient. Embodiments of such apparatus are provided comprising a first flow generator for delivering inspiratory gases, and a second flow generator for removing expiratory gases.Type: ApplicationFiled: April 30, 2021Publication date: August 22, 2024Inventors: David M. Rapoport, Kevin Blake Powell, Laurence Gulliver, Andre Van Schalkwyk, Kevin Peter O'Donnell

Patent number: 12053585Abstract: A gases humidification system includes a measuring chamber and a mixing chamber. The mixing chamber has one or more mixing elements that improve a mixing of gases before reaching the measuring chamber. Ultrasonic sensing is used to measure gases properties or characteristics within the measuring chamber. A baffle or a vane may be used to control and direct the gases flow through the mixing chamber as the gases flow moves into the measuring chamber.Type: GrantFiled: July 28, 2022Date of Patent: August 6, 2024Assignee: Fisher & Paykel Healthcare LimitedInventors: Andre Van Schalkwyk, Anthony James Newland, Rachael Glaves, Wenjie Robin Liang, Winnie Yong Jiang-Foo

Patent number: 12053587Abstract: Some embodiments provide for an inspiratory limb for a breathing circuit that includes a first segment that comprises a first heater wire circuit and a second segment that comprises a second heater wire circuit. The inspiratory limb can include an intermediate connector that includes a connection circuit that electrically couples the first heater wire circuit to the second heater wire circuit. The inspiratory limb can be configured to operate in two modes wherein, in a first mode, electrical power passes through the first electrical connection to provide power to the first heater wire circuit without providing power to the second heater wire circuit, and in a second mode, electrical power pass through the first electrical connection to provide power to both the first heater wire circuit and the second heater wire circuit.Type: GrantFiled: August 23, 2021Date of Patent: August 6, 2024Assignee: Fisher & Paykel Healthcare LimitedInventors: Matthew Liam Buswell, Helen Cuddy, Thomas James Edwards, Gavin Walsh Millar, Helgard Oosthuysen, Andre van Schalkwyk, Ian Lee Wai Kwan, Ping Si, Sinaa Alnashi, Kieran Michael Orchard, Ibrahim Al-Tiay, Elmo Benson Stoks, Charles Christopher North, Matthew Robert Wilson, Paul James Tonkin

Publication number: 20240058560Abstract: The disclosure relates to a patient interface for non-invasive ventilation. The patient interface is configured to seal about the mouth and nares of a patient and includes an outer wall defining an interior volume which includes a first chamber having one or more oral openings to communicate gas with the mouth and a second chamber having one or more nare openings to communicate gas with the nares. The patient interface further includes a dividing wall that separates the first chamber from the second chamber. The patient interface further includes one or more flow directors which enable gas to flow into the second chamber from the first chamber the first chamber from the second chamber. The one or more flow directors are configured to direct the gas flow through the one or more nare openings.Type: ApplicationFiled: January 12, 2022Publication date: February 22, 2024Inventors: James Alexander GORDON, Sascha Kristopher ZOELLNER, Joseph Jules NIHOTTE, Ashani Melisha PERERA, Vicky Dan GAO, Neil Gray DUTHIE, Saachi SHAHRI, Frederic Walter Williamson STRAUSS, Christopher WHARMBY, Ryan Anthony GRAHAM, Andre VAN SCHALKWYK

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: 20230347095Abstract: A flow of gases in a respiratory therapy system can be conditioned to achieve more consistent output from sensors configured to sense a characteristic of the flow. The flow can be mixed by imparting a tangential, rotary, helical, or swirling motion to the flow of gases. The mixing can occur upstream of the sensors. The flow can be segregated into smaller compartments to reduce turbulence in a region of the sensors.Type: ApplicationFiled: June 8, 2023Publication date: November 2, 2023Inventors: Hamish Adrian Osborne, Niall Christopher Denham, Mahran Maumoon Sujau, Andre Van Schalkwyk, Ivan Justus Rademeyer, Tessa Hazel Paris

Publication number: 20230144814Abstract: An apparatus for delivering a flow of gas has a housing, a cover, and a magnetic coupling system arranged to magnetically couple the cover—to the housing. Each of the housing and cover having complementary locating features, the locating features being adapted to locate and align the cover and the apparatus relative to each other to allow for the magnetic coupling. The apparatus also has a handle movably connected to the housing and is movable from a first position to a second position. The housing and the handle comprise complementary interlock features arranged to engage with each other when upward force is applied to the handle in the second position, and the interlock features are disengaged from each other when the handle is in the second position but upward force is not applied to the handle.Type: ApplicationFiled: June 24, 2022Publication date: May 11, 2023Inventors: Rachel Adeline Miller, Andrew Paul Maxwell Salmon, Andre van Schalkwyk, Ella Marie Meisel
