ERGONOMIC AND ADJUSTABLE RESPIRATORY MASK ASSEMBLY WITH 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, 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.

主权项

1. A patient interface assembly for CPAP therapy of a patient, comprising:
a frame with a central aperture; a cushion supported by the frame; an elbow adapted to connect to the frame at the central aperture; a strap assembly including a pair of relatively flexible strap portions having a relatively soft fabric and foam material construction, and a pair of stabilizing support members of a relatively rigid material compared to the strap material, each of said stabilizing support members being dimensioned and configured to rest across the patient's cheek regions in use and each of the stabilizing support members having a degree of flexibility in one direction such that variations in patient physiology can be accommodated in use, each said stabilizing support member having an integrally formed connector element in the form of a slot to receive a strap end of a respective one of the pair of strap portions, wherein the nasal mask assembly is not provided with a chin strap.
