Beschreibung
Zusammenfassung:	The invention relates to a patient interface for delivery of a flow of pressurized breathable gas to a patient for treatment of sleep disordered breathing, the patient interface comprising a nasal seal (17) configured to fluidly communicate the flow of pressurized breathable gas with nasal airways of the patient when the nasal seal is applied to the patient's nose without forming a seal on a nasal bridge region of the patient's face, and an oral seal (42) configured to sealingly engage around an exterior of the patient's mouth when applied to the patient's face, wherein the oral seal includes a side wall, a rim (53) extending away from the side wall, and a membrane (58) provided to substantially surround the rim, wherein the membrane is thinner than the rim, wherein the membrane is adapted to form a seal at least in a region of the patient's chin, and wherein the rim is adapted to add rigidity to the membrane at least in a region of the patient's cheeks.
