<p><P>PROBLEM TO BE SOLVED: To provide an oxygen concentrator capable of keeping electric power consumption low without deteriorating its therapeutic effect. <P>SOLUTION: The pressure swing adsorption type oxygen concentrator to generate oxygen concentrated gas, at least comprises no less than an adsorption tube containing adsorption agent for adsorbing nitrogen rather than oxygen, a source air supply means for supplying the adsorption tube with source air, and a flow channel switching means for controlling gas volume flowing into or out of the adsorption tube. The oxygen concentrator includes an oxygen concentration measuring means 6 for measuring oxygen concentration in the oxygen concentrated gas, and a control means 9 for changing supply capacity of the source air supply means from a measured value at the oxygen concentration measuring means 6 so as to keep the measured value within the range of 85-91%. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
