<P>PROBLEM TO BE SOLVED: To provide an oxygen tank unit for an oxygen concentrator, allowing simplification of a configuration of the periphery of an oxygen tank body and unitization. <P>SOLUTION: The oxygen concentrator has: a single oxygen tank body 51 connected to a pair of nitrogen adsorption containers alternately receiving supply of compressed air; check valves 60 interposed between the oxygen tank body and the pair of nitrogen adsorption containers, allowing a gas flow from the nitrogen adsorption containers to the oxygen tank body, and not allowing a gas flow reverse thereto; and a pressure reducing valve 70 connected to the oxygen tank body, and having an oxygen outlet. In the oxygen concentrator, at least one of a pair of nitrogen adsorption container-connecting tube bodies 60 each including the check valve and the pressure reducing valve 70 is directly installed onto the wall surface of the oxygen tank body to form this oxygen tank unit 50 for the oxygen concentrator. <P>COPYRIGHT: (C)2013,JPO&INPIT |
