<p><P>PROBLEM TO BE SOLVED: To provide an oxygen concentrator usable even when a patient is at home and/or out (including the time of moving inside a car or the like). <P>SOLUTION: The oxygen concentrator is provided with a compression means for compressing air taken in from the intake of the air, an adsorption means for adsorbing prescribed components other than oxygen inside the compressed air, inside an adsorption cylinder and removing them from the compressed air, a product tank for storing concentrated oxygen from which the prescribed components are removed, a pressure adjuster on the downstream side of the product tank, and an oxygen sensor provided in a place communicated with the downstream side flow path of the pressure adjuster, and is operable by an attachable and detachable battery. The compression means is structured such that a pressurizing function and pressure reducing function are provided, and an oxygen concentration is intermittently measured. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
