  • Patent number: 10933210
    Abstract: Nasal cannulas for providing respiratory therapy to patients can have a curved prong section that has turbulation elements on the inside curve of the prong. A flow of breathing gas moving through the prong may incur less resistance and create less noise when flowing through such a prong due to the promotion of favorable flow dynamics.

  • Patent number: 10926478
    Abstract: Welded headgear sections can be produced by using a weld tool having pins protruding from a weld region contact surface to deliver high-frequency electromagnetic energy to a weld region defined by overlapping top and bottom headgear straps. The pins fully penetrate the top strap and at least partially penetrate the bottom strap. The pins concentrate the electromagnetic energy to achieve a weld joint of acceptable weld strength and aesthetic appeal.

  • Patent number: 10918821
    Abstract: A breathing assistance apparatus and method of controlling a breathing assistance apparatus is disclosed. Particularly, the breathing assistance apparatus is controlled such that it has a drying cycle to enable drying of the tubing that supplies gases to a user and prevent the harbouring of pathogens within the tube. The drying cycle is preferably operated automatically by internal controllers in the apparatus. However, it may be manually activated by pressing a button on the apparatus. The drying cycle is preferably activated at the end of a user's treatment session.

  • Patent number: 10912489
    Abstract: A respiratory event determination system can have a controller that determines the presence of a respiratory event. The respiratory event can be a mouth puff event. The controller determines the presence as a function of a sub-window of an expiratory window of the breath. The expiratory window extends between a first time ti and a second time t2. The sub-window is limited to a portion of the expiratory window. The sub-window can extend between a third time t3 and a fourth time I4. The fourth time U can be before the second time t2.

  • Patent number: 10874814
    Abstract: 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.
