Abstract: 596486 A patient interface (200) for delivering breathable gas to a patient includes a sealing portion (210) including a nose tip engagement portion adapted to form a seal with the patient’s nose tip, an upper lip engagement portion adapted to form a seal with the patient’s upper lip and/or base of the patient’s nares, and nostril engagement flaps adapted to form a seal with the patient’s nares. The nose tip engagement portion, the upper lip engagement portion, and the nostril engagement flaps are all structured to extend outwardly from a supporting wall such that an area defined by an outer periphery of the sealing portion at a patient engaging side is greater than an area defined by an outer periphery of the sealing portion at a supporting wall engaging side, and wherein the supporting wall defines an air path.
