Publication number: 20240108847Abstract: A breathing assistance apparatus and method of controlling a breathing assistance apparatus is disclosed. Particularly, the breathing assistance apparatus is controlled such that it has a drying cycle to enable drying of the tubing that supplies gases to a user and prevent the harbouring of pathogens within the tube. The drying cycle is preferably operated automatically by internal controllers in the apparatus. However, it may be manually activated by pressing a button on the apparatus. The drying cycle is preferably activated at the end of a user's treatment session.Type: ApplicationFiled: May 26, 2023Publication date: April 4, 2024Inventors: Matthew Jon Payton, Kevin Peter O'Donnell, Christopher Simon James Quill, Ian Douglas Makinson, Emily Joy Drake, Craig Karl White, Virginia Louise Owen

Publication number: 20240091475Abstract: A respiratory assistance system can provide high flow therapy to patients. The respiratory assistance system can include a patient interface that can deliver a gas flow to a patient and a gas source that can drive the gas flow towards the patient interface at an operating flow rate. The system can include a controller for controlling the operating flow rate of the gas. The controller can apply multiple test flow rate values in a range as the operating flow rate. For each of the test flow rate values, the controller can measure a patient parameter. The controller can determine a new flow rate value based on the measured patient parameters.

Patent number: 11666726Abstract: The breathing assistance apparatus of the present invention includes a manifold that is provided with or retrofittable to gases supply and humidifying devices. The manifold allows gases from an oxygen concentrator to be combined with the flow through a gases supply and humidifying device, most usually air. The combined output of oxygen and other breathing gases (air) is then humidified. The breathing assistance apparatus and manifold of the present invention provides a safe method to add oxygen to the input air stream of a gases supply and humidifying device and reduces the amount of accumulation of oxygen within the gases supply device, reducing fire risk should sparking occur within the device.Type: GrantFiled: December 23, 2021Date of Patent: June 6, 2023Assignee: Fisher & Paykel Healthcare LimitedInventors: Martin Paul Friedrich Kramer, Kevin Peter O'Donnell, Christopher Simon James Quill, Matthew Jon Payton
