<p>A nasal mask assembly (10) for preferred use in CPAP treatment. The mask assembly comprises a central body (16), a gas inlet (18), a face cushion (14), and a brace (84). The central body has an inlet aperture (24) for receiving a delivered amount of gas and a rear rim (87). The gas inlet is rotatably disposed around the inlet aperture of the central body. A face cushion (14) having a front rim (78) is attached to the central body. The brace is supported within the central body and is shaped to conform to the contour of the central body's rear rim, leaving sufficient space between the brace and the rear rim that the front rim of the face cushion fits snugly and substantially air-tightly into the space. Thus, the brace acts to secure the cushion to the central body.</p> |
