Valve For A Pressure Breathing System Which Accomplishes The Valsalva Maneuver

US Patent:
5467766, Nov 21, 1995
Filed:
Oct 13, 1993
Appl. No.:
8/135740
Inventors:
William K. Ansite - Glendale CA
David N. Pennell - Apple Valley CA
Assignee:
Gentex Corporation - Rancho Cucamonga CA
International Classification:
A62B 902
A62B 1802
US Classification:
12820524
Abstract:
A pressurized breathing system enabling the execution of the Valsalva maneuver. A breathing mask has an inhalation valve and an exhalation valve. A Valsalva valve when in its normal position does not interfere with the regular performance of the system. When it is activated, it holds the exhalation valve closed. An exhalation effort of the wearer then accomplishes the Valsalva maneuver against the closed inhalation valve.
