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.

Swivel elbow and connector assembly for patient interface systems

A patient interface system for delivering a flow of breathable gas to a user includes a patient interface structure configured to sealingly engage the face of the user. The patient interface system further includes an elbow and connector assembly adapted to receive gases from a flow generator and deliver the gases to the patient interface structure. The elbow and connector assembly includes a ring attached to the patient interface, a sleeve, and an elbow. The ring includes an inner flange, an outer flange separated from the inner flange by a channel, and a plurality of vent slots extending through the inner flange, across the channel, and through the outer flange. The sleeve is configured so that inserting the sleeve into the ring forms a plurality of vent paths for the venting of exhalation gases from an interior of the patient interface to an exterior of the patient interface through the vent slots.

A swivel elbow and connector assembly for a patient interface system includes a ring configured to be sealingly secured in an aperture of the patient interface system. The ring includes 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 also includes a plurality of vents configured to permit flow of gases from the interior to the exterior of the patient interface system. The swivel elbow and connector assembly includes an elbow swivelably secured in the ring. A patient interface system for delivering a flow of breathable gas to a user includes a patient interface structure configured to sealing engage the face of the user. The patient interface structure includes an aperture. A swivel elbow and connector assembly is sealingly secured in the aperture.
