Description
本発明の各種態様は、概して、血液濾過システム、血液濾過透析システム、血漿交換システムなどの、血液透析等の新システムに関する。したがって、本明細書に記載の各種システムおよび方法は血液透析に関連して説明されているが、その他の透析システムおよび/または血液または血漿などのその他の体液を処理可能な体外システムにも適用可能であると理解すべきである。
カセットの別の実施形態を図35Aおよび35Bに示す。図35Aを参照すると、カセット4400は4つ以上の部分を含む。それらの部分は、中央プレートにレーザ溶接された複数カバー4412〜4416を有する中央プレート4410を含む。図34Aで4340として示されるポンププレートではなく、これらの複数カバー4412〜4416が使用される。図35Bを参照すると、中央プレート4410が再度示されている。しかし、本実施形態では、図34Aで4320として示される単一の作動プレートではなく、複数カバー4442〜4444が使用される。図35A〜35Cは一実施形態を示し、他の実施形態では、複数カバーの数は変更可能である。
式1は、測定ガスの体積を変化させることによって生じる温度変化または温度差が最小限であり、システムが略等温であると仮定する。温度変化が相当大きくなることのあるシステムの場合、使用される状態式によって定義されるように、当業者にとって自明である通り、測定流体の温度依存がサブステップ4(482)の体積算出に直接的に組み込まれる場合があると理解される。式1のVFはポンプチャンバ108の内体積を指し、VTはポンプチャンバ108、制御チャンバ110を含むシステムの体積と、測定流体入口ライン130およびシリンダ128に含まれる体積との既知の合計を指す。
