<P>PROBLEM TO BE SOLVED: To provide an oxygen concentrator capable of preventing occurrence of a fire, etc. by accurately and securely detecting a state of generation of flames such as smoking or use of a match. <P>SOLUTION: The oxygen concentrator 1 of a pressure-variable adsorption type generates an oxygen-concentrated gas from air by concentrating oxygen, and supplies the oxygen-concentrated gas for a user. The oxygen concentrator 1 includes: a cannula 9 connected to an oxygen concentrator body 2 for supplying the oxygen-concentrated gas for the user from the oxygen concentrator body 2 side; a gas introducing tube 13 connected to the oxygen concentrator body 2 and disposed along the cannula 9 for introducing the gas to the oxygen concentrator body 2 side from the vicinity of the user; a suction pump 107 connected to the gas introduction tube 13 for sucking the gas to the oxygen concentrator body 2 side; and a smoking detection sensor 109 for detecting smoking of the user from air sucked to the oxygen concentrator body 2 side by the suction pump 107. <P>COPYRIGHT: (C)2013,JPO&INPIT |
