Abstract

An oxygen concentration device (1) includes: a dehumidifying mechanism (lla) for dehumidifying air (AIR) taken in from outside; a compressor (12) provided downstream of the dehumidifying mechanism (lla), for compressing the air (AIR) dehumidified by the dehumidifying mechanism (lla); a nitrogen adsorption mechanism (13) for generating highly-concentrated oxygen (OXY) by causing nitrogen contained in the air (AIR) compressed by the compressor (11) to be adsorbed onto a catalyst; and a humidifying mechanism (llb) for humidifying the highly- concentrated oxygen (OXY) generated in the nitrogen adsorption mechanism (13) before the highly-concentrated oxygen (OXY) is sent out to the outside. The dehumidifying mechanism (lla) and the humidifying mechanism (llb) are integrally formed with a water-permeable film (llc) separating between the air (AIR) taken in from the outside and the highly-concentrated oxygen (OXY) generated in the nitrogen adsorption mechanism (13), and moisture in the air (AIR) in the dehumidifying mechanism (lla) is moved to the highly-concentrated oxygen (OXY) in the humidifying mechanism (llb) through the film (llc).
