Abstract
【解決手段】流路部材3の端部に取り付けた容器2は、吸入口6から吹き込まれる利用者の呼気によってふくらみ、恒温かつ恒湿の空気である呼気を溜める。流路部材3の流路に面して、吐出ヘッド4及び圧力センサー5が配置され、吸入口6からの吸入を圧力センサー5が検知する。吸入が検知されると、流路部材3内に薬剤が噴霧され、容器2内に溜められた呼気または空気とともに流動する。温度と湿度が一定である気流によって運ばれた薬剤は、一定の粒径で利用者に吸入される。

Description
本発明において、薬剤吐出部(吐出ヘッド)は任意の吐出圧発生素子を有する。すなわち、吐出原理としては、限定ではないが、粉末放出、MDI方式、ジェット式ネブライザー、超音波式ネブライザー、メッシュ式ネブライザー、カムによる押し出し方式、インクジェット方式、を含む。吐出圧発生素子としては、薬剤に熱エネルギーを付与する電気熱変換素子又は機械エネルギーを付与する電気機械変換素子が好ましい。すなわち、薬剤の吐出方式としては、電気熱変換素子を用いて薬剤に熱エネルギーを付与して吐出口から吐出させる方式(サーマルジェット方式)、薬剤に機械エネルギーを付与する電気機械変換素子(例えば圧電素子)の振動圧を用いて吐出口から薬剤を吐出する方式を例示できる。吐出方式については、薬剤の種類などに応じて選択可能である。
