Abstract
Disclosed is a novel improved nasal mask useful for patients suffering from respiratory ailments such as sleep apnea syndrome. The mask includes a shell having a contoured portion circumscribing the nasal area and side wings through which a retention strap passes. A seal is disposed between the shell and the patient's face providing a large contact area to distribute retention forces and reduce facial pressure. Transmission of external loads to and torques induced in the shell are minimized by orienting inlets proximate side wings and supporting a supply conduit along the strap.
