Title
(JA) 少なくとも1つの気体放出材料を有するマイクロポンプ
Abstract
(JA)

本発明は、半透性薄膜及び/又は流量制御部を通して放出される薬剤材料を含む第2の材料に向けてピストンを駆動する少なくとも1つの気体放出材料を有するマイクロポンプに関する。例えば本発明は、薬剤供給のためのマイクロポンプであって、少なくとも1つの第1のリザーバ、及び前記マイクロポンプにより放出されるべき薬剤がその中に配置されている少なくとも1つの第2のリザーバを有し、少なくとも1つの可動ピストン及び/又は変形可能薄膜が第1のリザーバと第2のリザーバとの間に提供され、少なくとも1つの気体放出材料が第1のリザーバ内に提供され、第2のリザーバが半透性材料及び/又は流量制御部を有し、当該半透性材料及び/又は前記流量制御部を通して前記薬剤が前記マイクロポンプにより放出されるマイクロポンプである。
