摘要： 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.

摘要： A product pump for pumping separated product gas from an oxygen concentrator which produces oxygen-rich product gas by utilizing a vacuum swing adsorption (VSA) process. The oxygen concentrator comprises a cartridge containing an adsorbent material for separating the product gas from ambient air, a vacuum pump which provides a vacuum source, a valve for selectively connecting the vacuum pump to the cartridge and product pump, and a reservoir. The product pump comprises a pumping chamber having a product gas inlet and a product gas outlet, a piston movable in the chamber, a vacuum inlet in the chamber on an opposite side of the piston from the product gas inlet and outlet for providing a vacuum to cause the piston to draw product gas through the product gas inlet into the chamber, and a spring for providing a spring force to force the product gas out the product gas outlet.
