<p><P>PROBLEM TO BE SOLVED: To provide an oxygen concentrator feeding oxygen concentrated air at a low concentration (for example, approximately 40%-60%) in the oxygen concentrator used for home oxygen treatment especially for an infant or a patient with a relatively light symptom. <P>SOLUTION: This oxygen concentrator is provided with an air compression means for feeding raw air, an adsorptive floor filled with adsorbent priorly adsorbing nitrogen in a first raw air fed from the air compression means, a concentrated oxygen regulating means regulating the flow rate of the oxygen concentrated air concentrated by the absorptive floor, a product gas tank storing product gas formed by mixing a second raw air fed from the air compression means with the oxygen concentrated air passing through the concentrated oxygen regulating means, and a flow rate setting device setting the flow rate of the product gas fed from the product gas tank. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
