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: 20230165993Abstract: The present invention provides a breathing assistance apparatus that has a convenient and effective method of cleaning internal conduits inside the apparatus. The breathing assistance apparatus is preferably a gases supply and humidification device. The cleaning method is a method of disinfection that is automated so minimal training is required to disinfect in particular an internal elbow conduit within the device. It is therefore not necessary to dismantle the gases supply and humidification device, therefore, inadvertent damage to the internal parts of the device is avoided. The present invention also provides a method of disinfecting a heated breathing conduit and a patient interface.Type: ApplicationFiled: December 27, 2022Publication date: June 1, 2023Inventors: Kevin Peter O'Donnell, Matthew Jon Payton, Christopher Simon James Quill, Martin Paul Friedrich Kramer, Peter Geoffrey Hawkins, Reena Daken
