Abstract
A mask for use in delivering air at a therapeutic pressure to a patient in need of therapy receives air from an air tube into an inelastic cloth mask portion that is attached to an interface portion constructed of an elastic material. The interface portion is a three dimensional structure that is attached at its edges to the mask portion and has a nose hole for receiving the patient's nose. When air is delivered the elastic interface portion pillows out and forms a seal against the patient's face. To assist with the seal, a structural assistance member may optionally be disposed on the interface portion above the nose hole so that it can be adjusted in the area of the bridge of the patient's nose.
