Abstract:
An oxygen control system for supplying a predetermined rate of flow of oxygen to a person in need of supplemental oxygen during periods of physical activity comprising:an oxygen source;an input manifold, an output manifold and a plurality of gas conduits interconnecting said input manifold to said output manifold, wherein said oxygen source is arranged in flow communication with said input manifold and said person is in oxygen flow communication with said output manifold;a needle valve positioned in flow control relation to each of said plurality of gas conduits so as to control the flow of oxygen from said input manifold to said output manifold;a plurality of solenoid valves each having a first closed state and a second open state wherein one of said plurality of solenoid valves is positioned in flow control relation to each but one of said plurality of gas conduits;means for monitoring the level of physical activity of said person; andmeans responsive to said physical activity monitoring means for sequentially switching said solenoid valves between said first state and said second state.
