<p>A rapid exhaust valve for use in a blood circulation stimulator which supplies and exhausts an air to and from an air bag provided on the human body, thereby subjecting to repeated pressure application and release. A valve box, which is provided with an exhaust port on the circumferential wall thereof, is provided with a flexible band valve diaphragm therein. If a compressed air is supplied into said valve box through a compressed-air supply pipe, said valve diaphragm is pushed by the pressure to close said exhaust port and a part of said valve diaphragm is projected into an air bag from an opening communicating with said air bag to allow the compressed air flow into said air bag. When the pressure in said air bag reaches high, said flexible valve diaphragm is deformed so that it may close said compressed-air supply pipe to release said exhaust port whereby rapidly discharging the compressed air out of said air bag.</p> |
