<p>PURPOSE:To obtain an oxygen-concentrated gas feeder capable of preventing generation of water droplets in a conduit means of oxygen-concentrated gas without causing uncomfortableness due to noise by equipping a foam type humidifying means generating low noise near to an oxygen-concentrated gas feeding means. CONSTITUTION:Air is force-fed to an adsorption bed with an adsorbent capable of selectively adsorbing O2 or N2 packed therein. O2-concentrated gas obtained from this adsorption bed is supplied to the necessary places through a conduit. In the meantime, this O2-concentrated gas is passed through a foam type humidifying means which is equipped near to an O2-concentrated gas feeding means in the conduit and generates low noise of <=34dB (A). Thereby a proper amount of moisture is given to the O2-concentrated gas ordinarily little in moisture content and thereafter this O2-concentrated gas is supplied e.g. to a patient. Further as the above-mentioned humidifier, such a device is preferably utilized that foams are generated from a face excepting the bottom face of a porous member equipped to the tip of a tube lengthened underwater, namely from only the side face and/or the top face thereof.</p> |
