<p><P>PROBLEM TO BE SOLVED: To provide a gas supplier for respiration which prevents dew from being condensed on the route of a piping system such as a tube for supplying humidified oxygen enriched air, a flow path where oxygen enriched air flows from being blocked and dew-condensed droplets or the like from being directly supplied to the nostrils of a user at the time of humidifying oxygen enriched air in a dry state supplied from an oxygen concentrator or an oxygen cylinder, or the like, by a humidifier. <P>SOLUTION: This gas supplier for the respiration comprises: a temperature detection means 32 for detecting a surrounding atmosphere temperature; a non water supply type humidifier 2 provided with a moisture permeating membrane for taking moisture contained in external air into the oxygen enriched air in the dry state; an external air taking-in means 23 for supplying the external air to the non water supply type humidifier 2; a dew point temperature detection means 31 for detecting the dew point temperature of the humidified oxygen enriched air which comes out from the non water supply type humidifier 2; and a controller 30 for controlling the amount of the external air to be taken-in to the non water supply type humidifier 2 on the basis of the surrounding temperature detected by the temperature detection means 32 and the detected dew point temperature. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
