Abstract: A respiratory mask made of cloth and having a nasal portion and an air delivery arrangement is disclosed. The cloth that is used is impermeable to air and is designed to provide a mask that will inflate to provide therapy to patients at a positive pressure. The air delivery arrangement provides air at positive pressure to the body of the mask via a hermetic seal.

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.

Abstract: A full face mask made of cloth having a nasal portion, an oral portion and transition portions is disclosed. The nasal and oral portions are made of a cloth that is impermeable to air and have nasal and oral interfaces on them to facilitate a seal with a user's face. The transition portions have easy removal clips for the lower headgear straps and sealing assistance members for better sealing.

Abstract: The invention is a frameless, disposable cloth body for use with a respiratory mask, such as for continuous positive airway pressure therapy for those having sleep apnea. The cloth body is inflatable and moisture-vapor breathable and has an inner side having a nasal interface portion disposed on it and an outer side, and also has a circular aperture formed in a central location on the body, sized to sealingly receive an air delivery arrangement. The cloth body also has a pair of wings on opposite sides with slits arranged at optimal angles for receiving headgear straps.
