Abstract
To provide an oxygen concentrator that can ensure safety by interrupting oxygen in a case where the oxygen concentrator is exposed to fire or an abnormal high-temperature environment when a user thereof is inhaling oxygen with a cannula. The oxygen concentrator includes: a compressor separating compressed air by compressing raw air; an oxygen outlet for discharging oxygen acquired from the compressed air; a coupler mounted on a tube of a cannula and removably connecting the tube to the oxygen outlet, and moreover having a temperature sensor; and a control unit stopping operation of the compressor to interrupt the supply of oxygen when a temperature sensed by the temperature sensor reaches a predetermined temperature or higher.
