Abstract

A patient interface for delivering pressurized breathable gas to a patient includes a flexible sealing portion with an orifice and sides that are adapted to engage with and form a seal with sides of the patient's nose. The orifice is configured so that a supply of breathable gas is deliverable to the patient through the orifice. The patient interface also includes a supporting portion that is in contact with and supports the flexible sealing portion. The patient interface further includes a pair of lateral headgear connector arms arranged at an angle with respect to the orifice in the flexible sealing portion. Each lateral headgear connector arm has a headgear tab. The angle between each lateral headgear connector arm and the orifice is adjustable. In addition, the flexibility of the lateral headgear connector arms allows the headgear tabs to touch an outer surface of the flexible sealing portion.
