The chemicals feeder in order to supply the aerosol which includes the chemicals to the patient (5,5 , 5 and 5 ), the mouthpiece component which in order the aerosol formation vessel in order to form the aerosol from resource of the chemicals (45,50,55,60) with, to be inserted into the mouth of the patient is formed (30,30, 30 and 30 ) with it includes. At the same time the mouthpiece component receives the aerosol and is connected to the aerosol formation vessel operational in order to supply the aerosol to the patient. In order as for the mouthpiece component, for the mouthpiece component to be inserted into the mouth of the patient and the time to confront in tongue of the patient, it possesses the underside which is formed, the tongue apex positioning element which is provided in the underside (90,90 , 90 and 115) it can possess. As for the underside, if it exists is, as for the tongue apex positioning element, in order in order to locate tongue just, apex of tongue of the patient to engage while using the chemicals feeder it is constituted.薬品を含むエアロゾルを患者に供給するための薬品供給装置(5,5’,5”,5”’)は、薬品の供給源からエアロゾルを生成するためのエアロゾル生成器(45,50,55,60)と、患者の口内に挿入されるよう構成されるマウスピース構成部品(30,30’,30”,30”’)とを含む。マウスピース構成部品は、エアロゾルを受け取り且つエアロゾルを患者に供給するためにエアロゾル生成器に動作的に結合される。マウスピース構成部品は、マウスピース構成部品が患者の口内に挿入されときに患者の舌に面するよう構成される下面を有し、下面に設けられる舌頂端位置決め素子(90,90”’,90”,115)を有し得る。下面は、もし存在するならば、舌頂端位置決め素子は、舌を正しく位置付けるために、薬品供給装置の使用中に患者の舌の頂端と係合するよう構成される。
