Abstract
An oxygen concentrator is disclosed which utilizes two molecular sieves to adsorb nitrogen out of compressed atmospheric air flowing therethrough so as to discharge oxygen enriched air for breathing purposes. Two such molecular sieves are used, one of which is operated in a regenerating mode while the other is operated in its adsorbing mode so a continuous supply of oxygen will be available to the patient. Periodically, the molecular sieves are automatically switched between their adsorbing and regenerating modes in such manner that the molecular sieve operating in its regenerating mode is incipiently recharged with high pressure, high oxygen quality gas prior to switching to its adsorbing mode. A method of operating the oxygen concentrator of this invention is also disclosed.
