Abstract
A patient interface includes a body member, a partition, a nasal seal portion, and a port. The partition is integral with the body member, and separates an interior of the member into a first chamber configured to receive a nose of a patient and a second chamber. The nasal seal portion is integral with the partition, and projects therefrom into the first chamber. The nasal seal portion includes a seal surface and a gas passage therethrough. The seal surface is configured to conform with a lower portion of the nose that is surrounding nasal passages of the patient, without entering the nasal passages of the patient, when the patient interface is mounted operatively on the face of the patient. The port integral with the member is in fluid communication with the second chamber for delivery of gas to the patient via the gas passage in the nasal seal portion.
