Description
本発明の分野は、乾燥粉末吸入器である。
患者の肺に薬剤を送るために吸入器が用いられている。典型的には、吸入器は、薬剤粒子と空気もしくは噴射剤との混合物を含有しているか、もしくは供給する。この混合物は、患者が吸入器上にあるマウスピースから吸い込むことにより、薬剤粒子が空気によって運ばれて、患者の肺に送り込まれる。
第一の態様において、単位用量乾燥粉末吸入器は、必要に応じて一つ、もしくはそれ以上のビーズの入った分散チャンバを有している。密封されたブリスター、もしくは用量容器がこの分散チャンバに隣接して支持されている。マウスピースカバーはマウスピースから取り外すことができ、マウスピースカバーの動きによって、ブリスターを破って、もしくは切って開けることができる。空気流路がブリスターの中、もしくは下を通って分散チャンバの中まで延びている。ブリスターは、吸入器の使用準備が整うまで密封されたままである。この後、マウスピースカバーをマウスピースから取り外すと、ブリスターが自動的に開く。使用者がマウスピースから吸い込むと、薬剤の乾燥粉末がブリスターから放出され、吸入器の中を流れる空気流中に浮遊されて運ばれる。この粉末は、分散チャンバ内で空気中に分散してエーロゾルを形成し、使用者によって吸い込まれる。
Claims (10)
- 一つもしくはそれ以上のビーズの入った分散チャンバと、

前記ブリスタープレートが空気入口前面溝を含んでおり、チャンバプレートの空気入口背面溝とブリスタープレートの空気入口前面溝とが、ブリスターポストの周囲を通って分散チャンバの中までつながった空気入口を形成している、請求項6の吸入器。 - シアプレートがヒンジを介してチャンバプレートに取り付けられており、マウスピースカバーによって押し下げられうるプレートタブを更に含んでいる、請求項5の吸入器。
- マウスピースカバーをマウスピースから外した時に、シアプレート上にあるブリスターポストがブリスタープレートから外れてブリスターが開くよう、プレートタブを押し下げるマウスピースカバー上に設けられたタブつめを更に含んでいる、請求項8の吸入器。
- シアプレートの第一の端がヒンジを介してチャンバプレートの第一の端に取り付けられており、またプレートタブがチャンバプレートの第一の端とは反対側にあるシアプレートの第二の端の上にあり、プレートタブをマウスピースカバーのタブつめによって押し下げる際に、シアプレートの第二の端をチャンバプレートとブリスターとから動かして離すことができる、請求項9の吸入器。
