Description
本発明は、体外血液処理のための装置、特に、透析装置に関し、処理液のための内部流体システムを有し、当該内部流体システムは、実質的に筒状のフィルタエレメントを前記内部流体システムに接続して処理液を前記フィルタエレメントに流すための少なくとも二つの液体コネクタを有する。前記装置は、更に、前記フィルタエレメントが前記内部流体システムの前記液体コネクタと体外血液ラインとに、意図される状態で接続することを可能にするべく前記フィルタエレメントを交換可能に保持するための土台を有する。
―透析器の片手セットアップが可能である。
―血液ラインが非常に短く、従って、ホース中の血液の量が減る。
―生体適合性の改善。
―血液ホースのコスト削減。
―透析器土台の非常に単純で費用効果の高い設計が可能である。
―DFラインでの温度/エネルギーの損失が少ない
―透析器の温度精度の改善
―消毒時間の短縮
―室内加熱の減少
―エネルギ節約

Claims (14)
- 体外血液処理のための装置であって、
処理液のための内部流体システムを有し、
前記内部流体システムは、実質的に筒状のフィルタエレメントを当該内部流体システムに接続して処理液を前記フィルタエレメントに流すための少なくとも二つの液体コネクタを有し、そして
