A mask system includes a frame adapted to attach headgear, a sealing arrangement releasably connectable to the frame, and an elbow provided to the sealing arrangement and adapted to be connected to an air delivery tube that delivers breathable gas to the patient. The sealing arrangement defines a breathing chamber and is adapted to form a seal with the patient's face. The sealing arrangement includes structure to establish a positive connection with the frame and with the elbow.

Mask system

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, and a frame component may be made in an overmoulding process that moulds the frame onto a pre-formed foam cushion. Such a moulding process may form a mechanical and/or chemical bonding of the foam and mask frame component. The mask frame component may be a shell of plenum chamber, such as for both nose and mouth. Various features of the cushion may further promote sealing and comfort for the under the nose design.

Foam cushion respiratory apparatus

An elbow for a respiratory mask includes a mask connection end adapted to connect to the mask and a tube connection end adapted to connect to an air delivery tube that delivers breathable gas to a patient. The mask connection end includes a first region constructed of a more rigid material and a second region constructed of a more flexible material. The second region provides flexibility to one or more portions of the mask connection end to enable engagement and disengagement of the elbow with the mask and/or sealing of the elbow with the mask.

Nasal mask system

A forehead support for a respiratory mask includes a forehead support arm structured to extend from a frame and a forehead support pad provided to the arm. The forehead support pad includes upper headgear connectors adapted to engage upper headgear straps and a flexible region. The upper headgear connectors are constructed of a first material and the flexible region is constructed of a second material that is more flexible than the first material to allow adjustment of the distance of the forehead support pad from the patient's forehead in use.

A mask system includes a frame () adapted to attach headgear, a sealing arrangement () releasably connectable to the frame, and an elbow () provided to the sealing arrangement and adapted to be connected to an air delivery tube that delivers breathable gas to the patient. The sealing arrangement defines a breathing chamber and is adapted to form a seal with the patient's face. The sealing arrangement includes structure () to establish a positive connection with the frame and with the elbow.

A nasal cushion for a mask system includes a side wall defining a breathing chamber, an undercushion extending from the side wall, and a membrane that at least partially covers the undercushion. The membrane is adapted to seal along the nasal bridge, sides of nose, corners of nose, and upper lip of the patient's face in use. The undercushion is only provided along the side of nose, corner of nose, and upper lip regions of the cushion. The undercushion includes a flap or extending portion in each side of nose region that is wider than the other regions thereof and adapted to engage and provide a force into the sides of the patient's nose in use.
