Patent number: 8020553Abstract: An oxygen concentrator comprises an oxygen reservoir and adsorbent columns that each have an inlet, an outlet, and a bed of adsorbent material. The concentrator also comprises an air inlet, an exhaust outlet, and a vacuum pump for pumping nitrogen rich gas from one of the column inlets to the exhaust outlet. A product control pump pumps oxygen rich gas from one of the column outlets to the oxygen reservoir. A control valve controls flow in and out of the columns by selectively connecting the air inlet to one column inlet, connecting the vacuum pump to another column inlet, and connecting the product control pump to a column outlet. A motor drives the vacuum pump and control valve to produce vacuum swing adsorption (VSA) cycles in which oxygen-rich product gas is separated and accumulated in the reservoir.Type: GrantFiled: February 9, 2005Date of Patent: September 20, 2011Assignee: Vbox, IncorporatedInventors: Theodore W. Jagger, Nicholas P. Van Brunt, John A. Kivisto, Perry B. Lonnes

Patent number: 7954490Abstract: Concentrated oxygen product gas is produced and delivered to a patient. Product gas is produced by (a) introducing ambient air into a first end of a column containing an adsorbent material that preferentially adsorbs nitrogen and removes oxygen-rich product gas out a second end of the column; (b) evacuating the column through the first end to remove adsorbed gas from the column; (c) repressurizing the column by introducing ambient air into the first end of the column until the column is near 1.0 atmosphere; and (d) repeating steps (a)-(c). Product gas is delivered as needed to the patient.Type: GrantFiled: February 9, 2005Date of Patent: June 7, 2011Assignee: Vbox, IncorporatedInventors: Theodore W. Jagger, Nicholas P.
