Patent number: 11471639Abstract: A respiratory interface, such as a mouthpiece, having a vestibular shield overlapping a user's teeth and gums, a gases passageway extending through the vestibular shield allowing for the passage of the gases through mouthpiece and an extra oral seal associated with the gases passageway, wherein the passageway in use causes gases to be diffused when exiting from the gases passageway. Mouthpiece may have an adjustment mechanism to alter distance between the vestibular shield and the extra-oral seal. The interface may include an elbow having a vent.Type: GrantFiled: March 31, 2020Date of Patent: October 18, 2022Assignee: Fisher & Paykel Healthcare LimitedInventors: Adam Alexander Tebbutt, Blair Albert Neal, Lewis George Gradon, Alastair Edwin McAuley, Mark Joseph Haycock

Publication number: 20220031984Abstract: 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: ApplicationFiled: September 23, 2021Publication date: February 3, 2022Inventors: Lewis George Gradon, David Robin Whiting, Andrew Gordon Gerred, Gregory Martyn Smith, Fiona Elizabeth Cresswell

Patent number: 10946158Abstract: 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: GrantFiled: November 9, 2018Date of Patent: March 16, 2021Assignee: Fisher & Paykel Healthcare LimitedInventors: Nicholas Charles Alan Smith, Alastair Edwin McAuley, Christopher Earl Nightingale, Ivan Milivojevic, Lewis George Gradon
