摘要： A patient interface assembly includes a frame with a central aperture by which a flow of pressurized breathable gas is introduced in use. The frame includes a wall on a central portion of the frame that surrounds the central aperture. A cushion is removably secured to the frame at the wall surrounding the central aperture and is made of a material that is relatively softer than the frame. A headgear assembly includes a pair of strap portions constructed of a flexible fabric material. A pair of yoke portions is positioned between the strap portions and the frame. Each yoke portion has a proximal end adjacent the frame and a distal end having a connector slot that connects to the respective strap portion of the headgear assembly. The yoke portions have a multilayer construction with one layer being a fabric layer. The yoke portions have a degree of flexibility in one direction and are more resistant to bending in another direction generally orthogonal to the one direction to resist vertical rotation of the patient interface assembly.

摘要： A respiratory mask assembly for delivering breathable gas to a patient includes a frame having a front surface and a rear surface, opposite the front surface, and adapted in use to face the patient. The frame defines an inner wall and an outer wall extending from the rear surface, the inner and outer walls being spaced to define a channel therebetween. A cushion is removably attachable to the frame such that the cushion and frame are repeatably engagable with and disengagable from one another. The cushion includes a side wall to be inserted into the channel of the frame, the side wall having a first interlocking surface that engages a second interlocking surface provided in the channel when the cushion and frame are engaged with one another. The first and second interlocking surfaces interlock with one another to removably attach the cushion to the frame.

摘要： A respiratory mask assembly for delivering breathable gas to a patient includes a frame having a front surface and a rear surface adapted in use to face the patient. The frame includes a main body providing an aperture therethrough for the introduction of breathable gas into a nasal breathing cavity. An elbow assembly is swivelably coupled to the front surface of the frame. The elbow assembly includes a swivel elbow that defines an intake port and an exhaust port separated from the intake port using a baffle. The elbow assembly includes an end portion that interfaces with the aperture of the frame.
