Abstract: A compressor (14) suitable for use in a portable oxygen concentrator (10). In one exemplary embodiment, the compressor includes a crankshaft (49) rotatable about a central axis and a plurality of diaphragm assemblies (46) spaced apart around the central axis generally within a plane. The diaphragm assemblies include diaphragms (50) movably mounted to respective housings to at least partially define chambers. A plurality of rods (44) extend between respective diaphragms and the crankshaft. The rods are coupled to the crankshaft such that the rods are offset axially from one another along the central axis and are coupled to the diaphragms for cyclically increasing and decreasing pressure within the chambers as the crankshaft rotates about the central axis.

Abstract: A portable oxygen concentrator (10) includes a pressure swing absorption system (12A, 12B) adapted to generate a flow of oxygen enriched gas and a battery (148) adapted to provide power to the pressure swing absorption system. The oxygen concentrator has a total weight of less than about 10 lbs, has a maximum flow of 100 % O 2 equivalent gas of about 0.9 lpm, has a total volume less than about 800 in 3 , and gas a battery life of at least about 8 hours. The present invention also using a liquefaction or transfill system in combination with such an oxygen concentrator.
