  • Patent number: 10004867
    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. 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.

  • Patent number: 10004864
    Abstract: A sealing interface includes an inner cushion and an outer sheath. The outer sheath substantially seals against the facial contours of the user. The inner cushion and the outer sheath each have a nasal bridge region, left and right cheek regions and either one of an upper lip region or a chin region. In use these regions are aligned with the corresponding nasal bridge region, left and right cheek regions and either the upper lip region or the chin region of a user. The inner cushion includes a hinged region. The hinged region is adapted to flex substantially independently of the inner cushion cheek regions.

  • Patent number: 9888858
    Abstract: Devices and systems provide methods for detecting cardiac signals from head or facial biopotential sensors. In one embodiment, a facial biopotential signal is measured by a set of sensors. A processor derives a cardiac signal from the facial biopotential signal. Optionally, heart rate is detected from the cardiac signal. Heart rate variability may be determined and evaluated by the processor to generate warnings or messages from the evaluation. One or more head or facial biopotential electrodes for measuring the facial biopotential signal may be integrated in or at a contact surface of head support structures such as a headgear support or respiratory treatment mask. In some such embodiments a controller of a respiratory treatment apparatus may serve as a cardiac signal detector by processing the facial biopotential signal from the sensors and may make control adjustments or generate warnings based on an evaluation of detected signals.
