Foregger Oxygen Flush Valve

WLMD ID: amwk

Oxygen flush valves provide for the rapid flow of oxygen into the anesthetic circuit.  Oxygen flush valves have been a feature of some anesthesia machines since the late 1930s, when they were first incorporated in the British-made Boyle machine.  In 1952, the Foregger Company of New York introduced the Copper Kettle Vaporizer. The lever that turned the vaporizer on and off also had a third setting that performed multiple functions; it operated as a fail-safe mechanism to stop the vaporizer, as a safety valve to prevent pressure buildup within the vaporizer, and as an oxygen flush valve. The Copper Kettle became an option on most Foregger machine models. The component shown here is part of a Foregger Texas Model machine, made between 1955 and 1962.
