<p><P>PROBLEM TO BE SOLVED: To provide an oxygen concentrator usable even when a patient is at home and/or going out (including the time of moving inside a car or the like). <P>SOLUTION: The oxygen concentrator comprises a compression means for compressing air taken in from an air intake, an absorbing means for absorbing prescribed components other than oxygen inside the compressed air inside an absorption 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 can be operated by a detachable battery. The oxygen sensor is an ultrasonic type, and an oxygen concentration is intermittently measured. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
