Abstract
This invention relates to an anesthesia dispensing device which comprises a turntable for carrying a plurality of vaporizers having an inlet and outlet port for each vaporizer, and a manifold having a feed port and an exhaust port with a passageway capable of providing communication between the feed port and an external gas supply and a passageway capable of providing communication between the exhaust port and the exterior of the dispensing device. The turntable and manifold are supported for relative rotational and reciprocal movement so that a vaporizer can be rotated into position, engaged and disengaged by simple manipulation. In a preferred embodiment, at least one directing chamber is disposed in the manifold with an inlet passageway providing communication between the directing chamber and gas supply, and with outlet passageways communicating between each directing chamber and the feed port and exterior of the device, and valve means associated therewith for directing flow either to the feed port or to the exterior. In this way, the unit can dispense anesthetic, a mixture of anesthetics, pure oxygen or a mixture of oxygen and other anesthetic gases as desired.
