Patent abstract
An elbow assembly for a mask assembly includes an anti-asphyxia valve (AAV) assembly that may take the form of a box-like frame work, a drop-in arrangement, or a slot-in arrangement. In each case, the AAV assembly may include a flap element which is movable so as to either direct ambient gas/air to the elbow assembly and thus the patient using the mask assembly, or to allow the passage of pressurized gas to the patient.
