摘要：
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.
