Abstract

A patient interface including a seal-forming structure having a mouth portion that forms at least part of the mouth plenum and is configured to seal around the patient's mouth and a nasal portion that is configured to seal with the patient's nares. The nasal portion includes a nasal plenum positioned to receive pressurized gas from the mouth plenum. The seal-forming structure also includes a clip configured to connect the mouth plenum to the nasal plenum and act as a conduit for the flow of the pressurized gas from the mouth plenum to the nasal plenum. The clip includes a mouth portion end configured to engage the mouth portion, a nasal portion end configured to engage the nasal portion, and a pair of wings protruding from the nasal portion end into an interior of the nasal plenum so that the wings engage an interior surface of the nasal plenum.
