Swivel elbow and connector assembly for patient interface systems

A swivel elbow and connector assembly for a patient interface system, comprising:

• a ring 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 swivelably secured in the ring,
• wherein the ring comprises a first flange on the first side and a second flange 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.
