摘要:
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.

A respiratory mask assembly for use in delivery of non-invasive positive airway pressure to a user comprising 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 further constructed and arranged to return to a relaxed state when the cushion is disassembled from the rigid mask shell, the soft cushion further 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.
摘要:
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.
