    Abstract: A swivel elbow and connector assembly (10) for a patient interface system, comprising: a ring (20) configured to be sealingly secured in an aperture of the patient interface system, the ring including a first side in an interior of the patient interface system and a second side at an exterior of the patient interface system when the ring is secured in the aperture, the ring comprising a plurality of vents (21) configured to permit flow of gases from the interior to the exterior of the patient interface system; and an elbow (40) swivelably secured in the ring. The ring comprises a first flange (22) on the first side and a second flange (23) on the second side, the first and second flanges defining a channel (24) that sealingly engages the aperture of the patient interface system. Vented gas is prevented from flowing between the ring and the elbow. The elbow and the portion of the ring between the first and second flanges form a ball and socket connection in which the portion of the ring between the first and second flanges has an elbow-facing surface with an arcuate cross-section and the elbow has a ring-facing surface with an arcuate cross-section.

    Abstract: A swivel elbow and connector assembly for a patient interface system, comprising: a ring (70) configured to be sealingly secured in an aperture of the patient interface system, the ring including a first side in an interior of the patient interface system and a second side at an exterior of the patient interface system when the ring is secured in the aperture, the ring comprising a plurality of vents configured to permit flow of gases from the interior to the exterior of the patient interface system; and an elbow (80) swivelably secured in the ring. The ring comprises a first flange (73) on the first side and a second flange (74) on the second side, the first and second flanges defining a channel that sealingly engages the aperture of the patient interface system and the second flange comprises an angled surface that directs the flow of gases from the plurality of vents at an angle to the longitudinal axis of the ring. A cross-section of an inner surface of the ring perpendicular to the direction of gas flow through the elbow is arcuate and a cross-section of an outer surface of the elbow perpendicular to the direction of gas flow through the elbow is arcuate to form a ball and socket connection with the ring.
