<p><P>PROBLEM TO BE SOLVED: To provide an adsorbing type oxygen concentrator as a medical device to be used at home for a long period of time, allowing a user to use the device without frequently cleaning a dust filter attached to an intake. <P>SOLUTION: The oxygen concentrator comprises at least one adsorbing barrel filled with an adsorbent to selectively adsorb nitrogen rather than oxygen, an air feeding means for feeding air to the adsorbing barrel, and the filter as the dust removing means attached to the intake for sucking air. The oxygen concentrator is characterized by a means for cleaning the filter. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
