Description
仮想弁40、51、及び53は、カセット1000が血液を伴って動作される間に、(水又は置換剤等よりも高い密度を有する)血液が、開いた仮想弁に「上向きに」或いは「横向きに」ほとんど侵入できないように配置されるが、これは、血液がより軽い水に比べて下降するからである。このような好適な配向が、仮想弁40、51、及び53を用いて実現される。一方、弁36はそのような要件を伴わず、即ち、そこでは配向は重要ではない。
繰り返しを避けるために、図1の説明で述べた、前述の個々の部品の構成を参照されたい。
以下に、本願の出願当初の特許請求の範囲に記載された発明を付記する。
[C1]
硬質部(1)及びフィルム(3)として具体化されたカセット本体を有する血液処理カセット(1000)であって、前記フィルム(3)は、前記硬質部(1)に結合されて、少なくとも部分的に前記硬質部(1)を覆い、
前記硬質部(1)は、弁(288)の少なくとも弁基体(226)を備え、前記弁(288)は、前記弁基体(226)と前記フィルム(3)の部分とが互いに接触しない、前記弁(288)の第1の開位置に加えて、前記フィルム(3)の部分に力を加えるときに、第2の位置をとるように具体化され、前記第2の位置において、前記弁基体(226)と、その上方に配置された前記フィルム(3)の前記部分とは互いに接触し、
