  • Publication number: 20200188617
    Abstract: A method of controlled delivery of breathing gases is described, during a first mode: the breathing gas inflow is predominantly through the first naris during inhalation; and the gas outflow is predominantly through the second naris during exhalation; and during a second mode that occurs after the first mode the breathing gas inflow is predominantly through the second naris during inhalation and the gas outflow is predominantly through the first naris during exhalation. The first mode and second modes are repeated. Also described is a system and apparatus implementing the method.

  • Patent number: 10603452
    Abstract: A method of controlled delivery of breathing gases is described the method comprising: applying breathing gas pressure within the first naris of a patient during inhalation; applying breathing gas pressure within the second naris of the patient during inhalation; applying breathing gas pressure within the first naris of the patient during exhalation; and applying breathing gas pressure within the second naris of the patient during exhalation, wherein the breathing gas pressure applied to the first naris during inhalation is higher than the gas pressure applied to the second naris during inhalation and the breathing gas inflow to the patient is substantially through the first naris during inhalation and wherein the breathing gas pressure applied to the first naris during exhalation is lower than the gas pressure applied to the second naris during exhalation and the gas outflow from the patient is substantially through the first naris during exhalation.

  • Publication number: 20180161536
    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: 8636002
    Abstract: A respiratory humidifier chamber for use with a breathing assistance apparatus is described. The chamber includes a water-tight vessel having an inlet for receiving gases from the breathing assistance apparatus, and an outlet through which heated humidified gases exit the vessel for delivery to a patient. The chamber has a partition which divides the chamber into upstream and downstream sub-chambers. The sub-chambers are separated by the partition except for an aperture which passes through the partition and allows gaseous communication between the sub-chambers. The downstream sub-chamber includes a heater base which heats a volume of water contained within it. The aperture is located above the volume of water. The upstream sub-chamber contains an internal heater which heats gases passing through it from the inlet to the aperture. At least part of the internal heater is located immediately adjacent the aperture.
