Abstract
A method and apparatus for testing flow control valves is disclosed. Specifically, the flow control valves of anesthesia machines are tested. The method contemplates the application of positive and negative air pressure to the valve being tested. If the valve is functioning properly, the valve will open or seal as expected. An apparatus is disclosed which enables a technician to apply either negative or positive pressure to the flow control valve and determine whether the valve is opening and sealing properly. The apparatus includes a pump for creating the air pressure and a fitting adapted to sealingly engage the port of the valve. The apparatus is simple to use and reduces the risk of transmitting disease.
