PROBLEM TO BE SOLVED: To provide a collunarium jetting device reliably eliminating fear that drug powder gets into a mass and thus the mass of the drug powder is taken in the nasal cavity of a patient, so as not to impose excessive burden on the patient when the drug is administrated.SOLUTION: The collunarium jetting device includes: a container body 1 provided with a flexible body part 1b a base 10 housing an inside container P attached to the container body 1 and charged with drug powder a lid 20 covering over the base 10 and forming a boring part 31 boring a hole into the inside container at the end of a cylinder 30 a nozzle 40 integrally connected to the lid 20 and forming an outlet passage H for the drug powder to the cylinder 30 and a mesh member 50 set up to the outlet passage H and having a plurality of pores. An air-introducing hole 16 is made at the ceiling wall 11 of the base 10 to send air in the inside space M into the lid 20 through the air-introducing hole 16 along with pressure of the body part 1b, and the drug powder is jetted out together with the air from a jetting outlet 41 through the mesh member 50 while mixing the air with the drug powder in the inside container P.COPYRIGHT: (C)2013,JPO&INPIT【課題】薬粉が塊状になってもこの塊が鼻腔内に取り込まれるおそれを確実に排除することができ、投与に際して患者に過度な負担を与えることがない点鼻薬噴出器を提案する。【解決手段】本発明の点鼻薬噴出器は、可撓性を有する胴部1bを備える容器本体1と、容器本体1に装着され薬粉を充填した内容器体Pを収納するベース10と、ベース10に覆い被さるとともに筒体30の先端に内容器体に孔を開ける穿孔部31を形成してなる蓋体20と、蓋体20に一体連結し筒体30との間で薬粉の出口通路Hを形成するノズル40と、出口通路Hに設けられ複数の微細孔を有するメッシュ部材50とを備え、ベース10の天壁11に空気導入孔16を設け、胴部1bの圧搾に伴って空気導入孔16から蓋体20内に内部空間M内の空気を送り込み、内容器体Pの薬粉と混合させつつメッシュ部材50を通して噴出口41から空気とともに薬粉を噴出させることを特徴とする。【選択図】図1
