PROBLEM TO BE SOLVED: To provide a suction type medicator which makes it possible not only to finely dispersing a medicine but also to avoid the scattering of the medicine even in the erroneous blowing-in of air.SOLUTION: In the suction type medicator equipped with a body 1 having a housing chamber M for housing capsules filled with the medicine, the perforation means 7 for perforating the capsules arranged in the housing chamber M of the body 1 and constituted so as to discharge the medicine taken out of the perforated capsules through the flow channel 1b (outside passage 1b2) of the housing chamber M, a dispersing route 3 and the ejection route 2a of a mouthpiece 2 along with the open air, an open air introducing passage 4, which is opened in the direction of crossing the flow channel 1b (outside passage 1b2) at a right angle and separately introduces the open air through a venting hole 4a at the time of suction of the medicine to accelerate the mixing with the medicine is provided on the upstream side of the flow channel 1b (outside passage 1b2) of the housing chamber M.COPYRIGHT: (C)2009,JPO&INPIT【課題】薬剤の微細、分散化を図り、かつエアーの誤った吹き込みにおいても薬剤の飛散を回避し得る吸引式投薬器を提案する。【解決手段】薬剤を充填したカプセルを収納する収納室を有するボディ1と、このボディ1の収納室Mに配置されたカプセルに孔を開ける穿孔手段7とを備え、穿孔されたカプセルから取り出された薬剤を外気とともに収納室Mの流通路1b(出側通路1b2)、分散経路3、さらにマウスピース2の噴出経路2aを経て排出する吸引式投薬器において、前記収納室Mの流通路1b(出側通路1b2)の上流側に、該流通路1b(出側通路1b2)に直交する向きに開通し薬剤の吸引時に通気孔4aを通して別途に外気を導入して薬剤との混合の促進を図る外気導入通路4を設ける。【選択図】図1
