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: 20230241336Abstract: According to this disclosure there is provided a respiratory support apparatus configured to provide a gases flow to a patient, the respiratory support apparatus comprising: a flow generator configured to generate the gases flow; a humidifier configured to humidify the gases flow; and a controller. The apparatus is controlled by the controller to function in at least two modes, being a normal mode and a high-temperature mode. In the high-temperature mode the temperature of gases delivered to the patient is higher than the temperature of gases delivered to the patient when in the normal mode. In the high-temperature mode, the controller controls one or more parameters of the gases flow to be different to that in the normal mode, whilst providing higher temperatures. The apparatus is also operative in a cool-down mode in which one or more parameters of the gases flow are controlled.Type: ApplicationFiled: July 7, 2021Publication date: August 3, 2023Inventor: Russel William Burgess

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: 20220016370Abstract: Systems and methods 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. The system can synchronize the flow rate with the detected breath cycle of the patient. The amplitude of the flow rate variation can be based partially on a value selected by the user. The adjustments to the flow rate can be done by controlling the motor speed using a positive feedback system. The adjustments to the flow rate can also be limited by the controller preventing the flow rate from crossing a minimum and/or maximum threshold.Type: ApplicationFiled: February 21, 2020Publication date: January 20, 2022Inventor: Russel William BURGESS
