Abstract: An apparatus and method for automatically controlling the flow of oxygen from a gas source is provided and includes the step of installing a gas concentrator device on an outlet port associated with the gas source. The gas concentrator device is configured to sealingly mate with a conduit connector for delivering a gas from the gas source to a conduit that is associated with the conduit connector. The method also includes the step of automatically providing gas flow from the gas source to the conduit by sealingly coupling the conduit connector to the gas concentrator device and whereupon removal of the conduit connector from the gas concentrator device causes the gas flow to automatically cease.

Abstract: A gas concentrator apparatus for supplying a gas to a patient and preventing leakage of the gas when a supply tube is removed from the gas concentrator apparatus includes a gas storage tank, a chamber, a piston, a membrane, a spring member, and the supply tube. The chamber is in gaseous communication with a gas storage tank for receiving the gas from the gas storage tank. The chamber comprises a piston configured to move the chamber in a forward direction or a reverse direction. The membrane is positioned at an end of the chamber distal to the gas storage tank. The membrane is actuated by a spring member to seal an entrance of the supply tube for preventing leakage of the gas when the supply tube is removed from the gas concentrator apparatus.
