Abstract: A mask system for delivering air to a user includes a suspension mechanism to allow relative movement between a face-contacting cushion and a mask shell. The suspension mechanism also provides a predetermined force to the cushion that is a function of mask pressure, displacement of the cushion or both.

Abstract: A respiratory mask assembly for delivery of non-invasive positive airway pressure to a user having a rigid mask shell including a plurality of slots; a soft cushion including at least one flexible sealing lip constructed and arranged to extend around an inner periphery of the cushion and to deform to provide a continuous airtight seal between the cushion and the rigid mask shell, the at least one flexible sealing lip being constructed and arranged to return to a relaxed state when the cushion is disassembled from the rigid mask shell, the soft cushion including a retaining portion; and a retaining ring configured to engage with the retaining portion of the cushion, and including a plurality of clips each positioned on respective spring arms to engage with each of the respective plurality of slots of the rigid mask shell to retain the cushion in position with the rigid mask shell.

Abstract: A respiratory mask for treatment of obstructive sleep apnea using gas pressurized in the range of about 4 to 20 cm H2O, the mask comprising a mask body, a flexible inlet tube having a first end coupled to the mask body and second end adapted to extend upwardly over a patient's head in use for connection to an air delivery tube. a cushion supported by the mask body, a harness to support the mask body and cushion on the patient's head, an elongated clip extending from each lateral side of the mask body, each said clip having a slot to receive an engaging strap of the harness, a ball and socket joint including a ball portion and a socket, wherein the ball portion comprises a part-spherical hollow profile, and wherein the ball portion and the socket are selectively attachable to and detachable from one another.

Abstract: A respiratory mask assembly for use in the delivery of non-invasive positive airway pressure to a user. The assembly includes a rigid shell having a channel portion defined by an inner wall, an outer wall and a channel floor, a face-contacting cushion acting to space the shell away from the user's face and a sealing tab extending from the cushion to engage a portion of the shell to provide a continuous airtight seal between the cushion and the shell. A retaining ring within the mask assembly is configured to secure the cushion to the shell. The retaining ring has a first portion including at least one clip configured to pass through at least one slot portion such that an underside surface of the at least one clip engages a section of the shell when the retaining ring is positioned within the channel.

Abstract: The present invention provides a vent assembly suitable for use with a respiratory mask of the type used in CPAP treatment. In one embodiment the vent is made of a thin air permeable membrane. Generally, the membrane is thinner than 0.5 mm. The membrane can be made of a hydrophobic material such as polytetrafluoroethylene (PTFE). The membrane can also be fabricated from expanded PTFE. The expanded PTFE membrane is mounted on a polypropylene scrim. The pores of the membrane have a reference pore size of 10 to 15 microns. In an alternative embodiment, the vent assembly includes a vent constructed from stainless steel. In another embodiment the membrane has a superficial cross-sectional area of approximately 500 mm2. In another embodiment the vent assembly comprises a membrane attached to a vent frame, the vent assembly forming an insert which can be removeably attached to a mask frame.
