A patient interface includes a frame assembly including connectors operatively attachable to headgear, a cushion assembly provided to the frame assembly and including a seal-forming structure structured to form a seal with the patient's nose and/or mouth, and an air delivery connector provided to the frame assembly and operatively connected to an air delivery tube for supplying the air at positive pressure along an air flow path. The cushion assembly is structured to releasably connect to the frame assembly independently of the air delivery connector. The air delivery connector is structured to releasably connect to the frame assembly independently of the cushion assembly.

Patient interface

A shroud for a mask system includes a retaining portion structured to retain a frame, a pair of upper headgear connectors each including an elongated arm and a slot at the free end of the arm adapted to receive a headgear strap, and a pair of lower headgear connectors each adapted to attach to a headgear strap. The retaining portion, the upper headgear connectors, and the lower headgear connectors are integrally formed as a one piece structure.

Mask system with shroud and vent holes

Pair of stabilizer arms for patient interface

A full-face mask assembly includes a frame and a cushion provided to the frame. The cushion is adapted to form a seal around the patient's nose and mouth. A flexible lip is provided to an interior wall of the cushion. The flexible lip is adapted to engage the frame to provide a seal in use.

Cushion/frame sub-assembly connectable to outer frame

Mask system with radially positioned vent holes

A cushion/frame assembly for a patient interface includes a cushion frame and a cushion. The cushion frame includes a cushion frame material, an annular wall portion having an opening that extends along a cushion frame longitudinal axis, and a projection extending radially with respect to the opening. The cushion frame is configured to snap fit with an outer frame having headgear attachment points and being configured to engage an inlet conduit. The cushion is connected to the cushion frame. The cushion is structured to form a seal with the patient and includes a cushion material that is more flexible than the cushion frame material.

Cushion/frame assembly for a patient interface

Mask system with snap-fit shroud

A mask system includes a frame defining a breathing chamber, a cushion provided to the frame and adapted to form a seal with the patient's face, and a shroud provided to the frame and adapted to attach headgear. The shroud includes a retaining mechanism structured to connect the shroud to the frame. The retaining mechanism includes both a taper lock arrangement and a retaining clip arrangement.

Mask system

Cushion to frame assembly mechanism

Mask system with shroud having extended headgear connector arms

A patient interface for delivery of a supply of pressurised air or breathable gas to an entrance of a patient's airways includes a frame member, a cushion assembly provided to the frame member, and an anterior wall member repeatedly engageable with and disengageable from the cushion assembly. The frame member includes connectors operatively attachable to a positioning and stabilizing structure. The cushion assembly includes a seal-forming structure and a void defined by an anterior surface of the cushion assembly. The anterior wall member has a predetermined surface area to seal the void of the cushion assembly and form a gas chamber when the anterior wall member and the cushion assembly are engaged. The void of the cushion assembly is sized such that the patient's nose and/or mouth is substantially exposed when the anterior wall member is disengaged from the cushion assembly thereby improving breathing comfort of the patient.

A mask system includes a cushion adapted to seal with a face of a patient. In one form an unobtrusive full-face masks system is provided which is comfortable and has a wide fit range. The cushion may include a sealing structure and a supporting structure. The supporting structure may include gaps or spacing in a nasal bridge region (NBR) and/or a lip region (CHN).
