Abstract

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.
