Customizable facial seal for masks delivering breathing gases in positive pressure ventilation systems

摘要

This device is a facial seal containing an internal bladder that is filled or pressurized with a quick set compound while on the face of the patient. The quick set compound conforms to the face of the wearer while in the seal itself, resulting in a better, substantially leakproof, fit. This is critical in applications where breathing gases are being supplied to the patient at greater than air pressure. One such application involves inflating the airway for the treatment of obstructive sleep apnea.
