A patient interface assembly includes a cushion assembly, and air delivery tube, and a connector assembly. The cushion assembly includes a flexible cushion including a base and a pair of nasal pillows that extend from the base and a frame that is more rigid than the flexible cushion. The connector assembly connects the air delivery tube to the cushion assembly and includes and elbow with a second end with a part spherical ball shape and a gas washout vent with a plurality of vent openings. The connector assembly also includes an elbow connector positioned in the frame. The elbow connector forms a part spherical socket shape that engages the part spherical ball shape of the elbow. The elbow connector includes an anchoring flange, which is configured to secure the flexible cushion to the elbow connector by way of the anchoring flange being inserted into the flexible cushion through a central opening in the flexible cushion.
