Abstract: A cushion for use in a system providing a flow of breathing gas to the airway of a patient includes a first end having a sealing flap structured to sealingly engage a surface of the patient about an airway of the patient and a second end adapted to receive the flow of breathing gas. A wall portion extends between the first end and the second end and defines a passage which extends between the first end and the second end and which is structured to communicate the flow of breathing gas from the second end to the first end. The wall portion includes a notch which is positioned and structured to deform in a predetermined manner such that an angle which the wall portion makes with a longitudinal axis of the passage increases from a first value to a second value upon deformation of the notch.

Abstract: A cushion member (10) for use in a pressure support system (2) for delivering a flow of breathing gas to an airway of a patient, the cushion member comprising:—a body portion (12) comprising a first end (14) and a second end (16) disposed opposite the first end, the body portion defining a passage (18) therethrough; and—a sealing portion (20) structured to sealingly engage about the airway of the patient, the sealing portion extending radially inwardly from the first end to an edge portion (22), the sealing portion having a notched portion (30) defined therein which extends outward from the edge portion.

Abstract: A patient interface device (8) includes a cushion member (16) structured to engage a face of a patient when the patient interface device is donned by a patient, and a frame assembly (14), wherein the cushion member is coupled to the frame assembly. The frame assembly including a main frame member (18) having a plurality of pocket members (32) provided therein, and a plurality of peg members (20) coupled to the main frame member, wherein each peg member includes an arm member (42) that is received and held within a respective one of the pocket members at a user selectable position, and where in movement of the peg members relative to the main frame member adjusts a size and/or shape of the patient interface device.
