Patent number: 9149597Abstract: An apparatus and method of controlling the delivery of therapeutic gas delivered to a patient undergoing positive airway pressure therapy is described. The method includes providing a flow of gas to a patient's airway at a pressure, obtaining information from the range of 0 to 25 Hz of the frequency domain of the flow, and adjusting the pressure based on the information. The apparatus includes a blower for providing a flow of gas to a patient's airway at a pressure, a sensor to measure a characteristic of the flow, a controller to obtain information from the range of 0 to 25 Hz of the frequency domain of the characteristic, and a pressure regulator for adjusting the pressure based on the information.Type: GrantFiled: January 3, 2011Date of Patent: October 6, 2015Assignee: FISHER & PAYKEL HEALTHCARE LIMITEDInventors: Lewis George Gradon, David Robin Whiting, Andrew Gordon Gerred, Gregory Martyn Smith, Fiona Elizabeth Anderson

Publication number: 20150273169Abstract: The present invention relates to a device for delivering a supply of gases to a patient. The device includes a patient interface and connecting member. The connecting member is preferably a L-shaped swiveled connector that is capable of being fixed into one of two positions, a first position where the connector is freely rotatable within the patient interface, and a second position where an interference between the interface and connector prevents the free rotation of the connector within the patient interface, The present invention further relates to a connector that has outlet means, which includes at least one outlet vent and a funnel, which in use directs and passes a substantial portion gases expired from the patient through the outlet vent or vents.Type: ApplicationFiled: March 6, 2015Publication date: October 1, 2015Inventors: Nicholas Charles Alan Smith, Alastair Edwin McAuley, Christopher Earl Nightingale, Ivan Milivojevic, Lewis George Gradon

Patent number: 7849852Abstract: A medical breathing assistance apparatus (20) for supplying pressurised gases to a patient is disclosed. The breathing assistance apparatus (20) comprises a heating chamber (29) and a pressure chamber (27) both adapted to contain water, and at least one pressure adjusting means (24,25,26). The pressure chamber (27) is connected to the heating chamber (29) and the pressure adjusting means (24,25,26) is located between the heating chamber (29) and a gases supplying means (23) supplying gas to both the pressure chamber (27) and heating chamber (29). The pressure adjusting means (24,25,26) is adapted to convert pressurised gases from the gases supply means (23) to two different pressures, one to each of the heating chamber (29) and the pressure chamber (27), so that water flows from said pressure chamber (27) to the heating chamber (29).Type: GrantFiled: February 3, 2004Date of Patent: December 14, 2010Assignee: Fisher & Paykel Healthcare LimitedInventors: Michael Brian Edward Bremner, Lewis George Gradon
