초록 ▼

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.

대표청구항 ▼

1. An arrangement for use in a respiratory mask assembly, comprising: a ball and socket mechanism for connecting a breathable air inlet in the respiratory mask;a curved connector tube configured to permit air flow to an interior of the respirator mask assembly; anda ball portion being configured to mount in a socket at the end of an air tube, the air tube being configured to connect to a pressurized air source, the ball portion being insertable into and removable from the socket, each of the ball portion and the socket has a hollow part-spherical profile, andwherein the socket includes an inner circumferential seat and a lip at an outer edge of the socket,and wherein the ball portion and socket are constructed and arranged so that in use, the ball portion is free to rotate with respect to the socket and to allow a small amount of pressurized air to escape between the ball portion and socket,and further wherein, once the ball portion is in a static position, air pressure forces the ball portion to seal against the lip. 2. The arrangement of claim 1, wherein the air tube is composed of a flexible material. 3. The arrangement of claim 1, wherein pressurized air from the air tube flows through an orifice in the ball portion to the curved connector tube. 4. The arrangement of claim 1, further comprising a base plate portion configured to mount the arrangement to a user's forehead. 5. The arrangement of claim 1, wherein the arrangement is directly attached to a surface of a shell of the respiratory mask assembly. 6. The arrangement of claim 1, wherein a clearance is provided between the ball portion and the inner circumferential section, the clearance extending from the seat to the lip. 7. The arrangement of claim 1, wherein an inner surface of the ball portion is part spherical and concave. 8. The arrangement of claim 1, wherein the ball portion includes a spherical wall portion having an outer surface to contact an inner surface of the socket, and a concave inner surface having a part-spherical shape. 9. The arrangement of claim 1, wherein the ball portion comprises a first material and the socket comprises a second material that is different from the first material. 10. The arrangement of claim 9, wherein the first material is relatively hard compared to the second material, which is relatively more flexible. 11. The arrangement of claim 1, wherein the ball portion comprises polycarbonate. 12. The arrangement of claim 11, wherein the socket comprises polypropylene. 13. The arrangement of claim 1, wherein the ball portion and the socket comprise polycarbonate. 14. The arrangement of claim 1, wherein each of the ball portion and the socket comprises only a portion of a sphere. 15. The arrangement of claim 1, further comprising a clearance between an outer surface of the ball portion and an inner surface of the socket, the clearance being positioned between the seat and the lip, such that only the seat and the lip contact the outer surface of the ball portion.
