I will provide a gas mist inhaler excellent effect and convenient using the physiological action of oxygen or carbon dioxide gas. Oxygen, carbon dioxide, or a liquid reservoir which is connected with gas supply means (110), gas supply means (110) a mixed gas of carbon dioxide and oxygen, for storing the liquid, pressurized gas supply gas mist generation having a nozzle for a liquid absorbing tube for feeding a liquid to the nozzle tip, vent holes for taking in outside air, and (127), to produce a mist which was crushed and dissolved. gas and the liquid and a suction member having a suction port for means (120) is connected to (120) the gas mist generating means, and to be taken to a living body of the gas mist and a (140), wherein the gas mist generating means (120) further comprises: separately, with a gas introducing means for supplying a gas mist generation means (120) in, I raise the supply pressure of the gas mist inhalation member to the (140) and the nozzle.炭酸ガス又は酸素の生理作用を利用した簡便かつ効果の優れたガスミスト吸入器を提供する。酸素、炭酸ガス、又は酸素と炭酸ガスの混合ガスを供給するガス供給手段(110)と、ガス供給手段(110)に接続されると共に、液体を貯留する液体貯留部と、ガスを加圧供給するノズルと、そのノズル先端に液体を送液する吸液管と、外気を取り込むための通気孔(127)と、を有し、前記液体とガスとを粉砕溶解させたガスミストを生成するガスミスト生成手段(120)と、このガスミスト生成手段(120)と接続され、前記ガスミストを生体に吸入させるための吸入口を有する吸入部材(140)と、を備え、前記ガスミスト生成手段(120)がさらに、前記ノズルとは別途に、ガスミスト生成手段(120)内にガスを供給するガス導入手段を備え、吸入部材(140)へのガスミストの供給圧を上げる。
