Abstract

A patient interface for delivering breathable gas to a patient includes a nasal prong assembly including a pair of nasal prongs structured to sealingly communicate with nasal passages of a patient's nose in use and headgear to maintain the nasal prong assembly in a desired position on the patient's face. The headgear includes side straps and rigidizers provided to respective side straps. Each rigidizer includes a first end portion that provides a connector structured to engage a respective end of the nasal prong assembly and an inwardly curved protrusion in the form of a cheek support that curves inwardly of the connector. The cheek support is adapted to follow the contour of the patient's cheek and guide a respective end portion of the side strap into engagement with the patient's cheek to provide a stable cheek support.
