[Problem] To provide an oxygen concentration device capable of reliably detecting fire and ensuring safety during use, in the event that, when a patient is using a nasal cannula or other oxygen breathing equipment to inhale oxygen, the cannula or a tube has ignited as a result of an accidental or other fire. [Solution] An oxygen concentration device (10) comprising: a coupler socket (400), for example, that is arranged at an appropriate position in a cannula (22) and which is a detection unit holding tool having a temperature sensor (320) being a detection unit that detects that the cannula (22) has ignited; and an oxygen isolation unit (500) that, by receiving a signal from the temperature sensor (320) being the detection unit, determines that the cannula (22) has ignited and blocks supply of concentrated oxygen. |
