Estimating the term…
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.
A mask cushion assembly for a patient interface of a respiratory treatment apparatus, the mask cushion assembly comprising a peripheral foam cushion adapted as a seal for a mouth portion, the peripheral foam cushion further adapted as a seal for a nasal portion, the cushion assembly further comprising a flexible support component peripherally engaged with the foam cushion and a rigid support component coupled with the flexible support component, wherein the flexible support component is formed of an air impermeable material.
A mask cushion for a mask frame comprising a foam cushion, the mask cushion including a peripheral portion adapted as a seal for a mouth portion, the peripheral portion further adapted as a seal for a nasal portion, the foam cushion further comprising a stretchable engagement skirt, whereby the foam cushion is configured as a slip-over foam cover for a supporting structure.
A mask cushion assembly for a mask frame comprising a foam cushion, the foam cushion including a peripheral portion adapted as a seal for a mouth portion, the peripheral portion further adapted as a seal for a nasal portion, the mask cushion assembly further comprising an inner peripheral clip and outer peripheral clip, the clips configured to engage with a foam support component, the inner peripheral clip engaging on an inner side of the foam cushion and the outer peripheral clip engaging on an outer side of the foam cushion, the clips clamping the foam cushion to secure the foam cushion to the foam support component.
