Abstract: Apparatus to permit a delivery of a flow of breathable gas to a patient's airways. In one version, a coupler extension may include a seat portion to permit use of a mask with a nasal cannula. In some versions, the coupler extension is configured to conduct the flow of gas to prongs of a nasal cannula. The seat portion can receive and seal with a cushion of a respiratory mask and may have a sealing bevel to promote sealing between the cushion of the respiratory mask and a facial contact surface of a user. In some versions, a conduit adapted to communicate a flow of gas may comprise a slit valve formed by a portion of the wall material of the conduit. In some versions, a nasal interface may include naris pillows to seal with and conduct a flow of breathable gas into a nares of a user. Each naris pillow may include a nasal projection to conduct a further flow of gas. The nasal projection may extend within the naris beyond the seal of the naris pillow.

Abstract: A mask apparatus for a respiratory treatment can permit delivery of breathable gas to a user. In one example, the mask may employ a frame and cushion to form a seal for both mouth and nose. The frame may be adapted for coupling with a respiratory treatment apparatus so as to permit communication of a pressurized gas from the respiratory treatment apparatus. The cushion, which may be foam, may have a substantially under the nose configuration or over the nose configuration. The mask may have a common plenum chamber for both nose and mouth. The cushion may further define a centrally open lip superior region. The cushion may be adapted to couple with the frame directly or to the frame in conjunction with a cushion support clip. Various features of the cushion may further promote sealing and comfort for the under the nose design.

Abstract: Components for a respiratory treatment apparatus that is capable of providing a humidified respiratory treatment permit a reduction in condensation in a patient interface and/or its gas delivery tubing. In some embodiments, a rainout valve that may be an integrated component of a humidifier output aperture, or coupled thereto, may reduce condensation with a vapor barrier operable to selectively block and permit humidified gas transfer from the humidifier. For example, the barrier may be operable to open in response to a flow of pressurized breathable gas that may be generated by a flow generator of the respiratory treatment apparatus. In the absence of such a generation of pressurized flow, the barrier may prevent a transfer of the humidified gas such as into a conduit for a patient interface by retracting to a closed position. Example vapor barriers may include a resilient membrane, cover, bellows, flap, shutter or other suitable valve.

Abstract: A humidifying apparatus utilizing a semi-permeable membrane portion within a gas conduit where the direction of gas flow within a central lumen is given by an arrow. The humidification apparatus has a helical configuration for the semi-permeable membrane portion, a structural reinforcing member or members, a water channel and a heating element. The helical configuration of an outer wall may be similar to conventional conduits that are in common use in respiratory apparatus. Thus the humidification apparatus may be readily substituted into existing respiratory device by exchanging the gas conduit.

Abstract: Devices and systems provide methods of controlling breathable gas generation such as for a respiratory treatment and/or for controlling ionization of the gas. In an example, a controller of a respiratory treatment apparatus controls generation of a supply of ionized air. The apparatus may include a flow generator to generate a flow of pressurized breathable gas. The flow generator may be adapted for connection with a respiratory interface. The apparatus may also include an ionizer to ionize the flow of gas. The controller may be coupled with the ionizer and the flow generator and be configured to control the ionizer to programmatically change levels of ionization of the gas. Such ionized gas treatments may be suitable for helping users to sleep or improving respiratory oxygen absorption, and may be for patients with, for example, sleep disordered breathing or chronic obstructive pulmonary disease.
