Publication number: 20200171189Abstract: 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: November 5, 2019Publication date: June 4, 2020Inventors: Kevin Peter O'Donnell, Matthew Jon Payton, Christopher Simon James Quill, Martin Paul Friedrich Kramer, Peter Geoffrey Hawkins, Reena Daken
