Abstract
【解決手段】マウスピース4の気流路20内に薬剤を吐出する吐出ヘッド8aには、連結管8bを介してタンク7内の薬剤が供給される。吐出ヘッドのノズル(オリフィス)に薬剤が付着して吸入量が減少するのを補うために、吸入ごとにタンク内の薬剤の残量を歪ゲージ37を用いて計測し、次回の吸入時における吐出ヘッドの吐出動作期間を調整して所定の薬剤吐出量を維持する。
【選択図】図5
Description
図1は、本発明の薬剤吐出装置の一例としての吸入装置の外観を示す斜視図である。吸入装置本体は、ハウジングケース1およびアクセスカバー2で外装を形成している。図2に示すように、アクセスカバー2はロック用のフック部3を備えており、マウスピース4は、ハウジングケース1内に着脱自在に装着される。
(21−9)÷7.5=1.6 sec
そして、1.6秒だけ吐出するように制御部により吐出ヘッドの駆動を行うことで、全体投与量を精度良く確実に吐出することができる。
図7は、実施形態2による吸入装置を断面で示す。利用者の1回の吸入における薬剤吐出量としてタンク7の薬剤残量を測定する歪ゲージ37の代わりに、薬剤吐出ユニット6の吐出速度(単位時間あたりの吐出量)を光学的に計測するための光学手段である投光器41、42および受光器43、44を用いた。それ以外は、実施形態1と同様の構成である。
