Description
この出願は、2004年12月3日に出願された特許出願第11/004670号「Fluid Delivery System, Fluid Path Set, Sterile Connecter and Improved Drip Container and Pressure Isolation Mechanism」の利益を主張し、前記特許出願は、係属中の以下の特許出願の開示に関連する主題を含んでいる:(1)出願番号第10/826149号(2004年4月16日出願);(2)出願番号第10/818748号(2004年4月6日出願);(3)出願番号第10/818477号(2004年4月5日出願);(4)出願番号第10/326582号(2002年12月20日出願);(5)出願番号第10/237139号(2002年9月6日出願);(6)出願番号第09/982518号(2001年10月18日出願)。これらの開示は引用を以て本願への記載加入とする。
本発明は、全体としては、医療の診断及び治療処置において流体を供給するための流体送給システムに関し、さらには、流体移送アッセンブリ、及び、該流体移送アッセンブリに連繋されて、流体流れの生成及び調節を行なう流体送給システムと共に用いられる流れ制御及び調節装置に関する。
多くの医療診断及び治療処置において、医者又はその他の使用者から、患者に対して、流体の注入が行われている。近年では、血管造影法、コンピュータ断層撮影、超音波及びNMR/MRIのような処置において、流体(例えば、造影剤)を加圧注入するために、数多くのインジェクター作動型シリンジ及びパワーインジェクターが開発されている。一般的に、これらのパワーインジェクターは、予め設定された量の造影剤を、予め設定された流速で送給できるように設計されている。
