Respiratory mask with disposable cloth body

摘要

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.
