摘要：
A patient interface including a nasal seal including a face contacting side. The nasal seal is formed of a soft flexible material, and includes a central portion to extend across the base of the nose, and a side portion extending from each end of the central portion. Each side portion extends across the a side of the nose. A face contacting side of the seal is supple to conform under internal pressure to the surfaces of the nose of a wearer, including, at the side portions of the seal, to outside surfaces of the sides of the nose. An exterior side includes regions much stiffer than the supple interior side, the regions extending into the side portions of the seal.
