Patent number: 10874814Abstract: A headgear system and/or an interface assembly incorporating a headgear system that, in some configurations, is configured to transform from elasticated or “stretchy” behavior to “inelastic” behavior at least in response to normal or expected forces encountered during the intended therapy. In some configurations, upon fitment to the head of a user, the system automatically adjusts toward or to an appropriate size. A headgear portion or assembly for use in combination with a breathing apparatus in some configurations is at least substantially inelastic and is three dimensional in shape. The headgear portion or assembly can comprise a plastic core and a textile casing. The headgear, or part thereof, may also have integrally moulded labels, connectors, adjustment mechanisms and/or grips.Type: GrantFiled: September 16, 2015Date of Patent: December 29, 2020Assignee: Fisher & Paykel Healthcare LimitedInventors: Brett John Huddart, Jeroen Hammer, Matthew Robert Geoff Slight, Vitaly Kapelevich, David Monroy Felix, Callum Ross Gordon, Bruce Michael Walls, Melissa Catherine Bornholdt, Matthew Roger Stephenson, Paul Mathew Freestone, Ryan Anthony Graham, Mark Arvind McLaren

Patent number: 10874817Abstract: A pressure swing adsorption (PSA) system and methods for controlling each PSA cycle performed by the PSA system to produce oxygen enriched gas during productive portions of a user breathing cycle, and to cease production of oxygen enriched gas during non-productive portions of the user breathing cycle, is provided. The PSA system synchronizes PSA cycle phases including adsorption and desorption phases with a user's individual inhalation and exhalation phases, on a breath by breath basis, such that each PSA cycle can be dynamically varied from a succeeding PSA cycle, in real time in response to variations in the user's breathing cycle. An oxygen delivery device including a breathing cycle sensor provides breathing cycle inputs to a controller for use with at least one algorithm to detect breathing flow phases during each user breath, and to synchronize each PSA cycle to the user's breathing flow phases, on a breath-by-breath basis.Type: GrantFiled: September 9, 2020Date of Patent: December 29, 2020Assignee: Aires Medical LLCInventors: Nicholas L. Oddo, Peter D. Fitchen, Eugene H. Breniman

Patent number: 10874819Abstract: A gas humidification system can have a conduit defining a gas passageway. A mass of a first absorbent material can be located in the conduit. A mass of a second absorbent material can cover at least a part of the surface of the conduit. An orifice can be located on the conduit to allow communication between the first and second absorbent materials. A heating element can be placed within, on, around, or near the first absorbent material. The heating element can heat up moisture in or on the first absorbent material such that the moisture is encouraged to join gases passing through the gas humidification system.Type: GrantFiled: March 13, 2015Date of Patent: December 29, 2020Assignee: Fisher & Paykel Healthcare LimitedInventors: Andrew Paul Maxwell Salmon, Guohua Bao, Nordyn Alami
