Publication number: 20200179629Abstract: 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: December 2, 2016Publication date: June 11, 2020Inventors: Russel William Burgess, Jess Edward Donnelly, Dean Antony Barker, Philip John Dickinson, Andre Van Schalkwyk, Joel Michael Lawson

Publication number: 20200054847Abstract: A respiratory flow therapy apparatus including a sensor module can measure a flow rate of gases or gases concentration provided to a patient. The sensor module can be located after a blower and/or mixer. The sensor module can include at least an ultrasonic transmitter, a receiver, a temperature sensor, a pressure sensor, a humidity sensor and/or a flow rate sensor. The receivers can be immersed in the gases flow path. The receivers can cancel delays in the transmitters and improve accuracy of measurements of characteristics of the gases flow. The receivers can allow for detection of a fault condition in a blower motor of the apparatus.Type: ApplicationFiled: April 13, 2018Publication date: February 20, 2020Inventors: Russel William Burgess, Dean Antony Barker

Publication number: 20190240432Abstract: A gases flow rate sensing system may be configured to operate in at least two different target temperature modes, based upon a measured temperature of the gases flow. In some embodiments, the gases flow sensing system may have a voltage divider containing a thermistor. The gases flow rate may be determined based upon a voltage output indicating an amount of power needed to maintain the thermistor at a target temperature as specified by the target temperature mode, and a measured temperature of the gases flow.Type: ApplicationFiled: September 13, 2017Publication date: August 8, 2019Inventors: Russel William Burgess, Houde Huang

Publication number: 20190217030Abstract: 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: May 17, 2017Publication date: July 18, 2019Applicant: Fisher & Paykel Healthcare LimitedInventors: Russel William BURGESS, Dean Antony BARKER, Kevin Peter O'DONNELL
