PROBLEM TO BE SOLVED: To prevent the erroneous operation of performing transfusion without performing the opening operation of a weak seal part, relating to a multi-chamber type container comprising a medical fluid bag formed of a flexible synthetic resin film and provided with a plurality of compartments separated by the weak seal part and a small amount medical agent container attached to the medical fluid bag, for mixing and discharging a medical agent in the medical agent bag and the medical agent in the medical agent container.SOLUTION: The medical agent container 16 is attached to the outer periphery of the medical fluid bag 10. A medical agent housing chamber is formed in the medical agent container 16, a closing implement for closing a communication path for communicating the medical agent housing chamber to the inside of the medical agent bag is connected to a cap 30 through a screw means, and a closing member is turned to be in an open state by the rotating operation of the cap 30. A valve member 40 constituting the closing implement is positioned closely to the weak seal part 10B for separating upper and lower compartments, and an operation for opening the medical agent container positions (40) the valve member 40 so as to forcibly peel off a peelable welded part.COPYRIGHT: (C)2008,JPO&INPIT【課題】本発明は可撓性の合成樹脂フィルムにて形成され、弱シール部により分離される複数の隔室を有した薬液バッグと薬液バッグに取り付けられる少量薬剤容器とを備え、薬剤バック中の薬剤と薬剤容器中の薬剤とを混合して排出するようにした複室型容器に関するものに関し、弱シール部の開通操作を行わないまま輸液を行ってしまうという誤操作を防止することを目的とする。【解決手段】薬剤容器16は薬液バッグ10の外周に取り付けられる。薬剤容器16に薬剤収容室が形成され、薬剤収容室を薬剤バッグ内部に連通せしめる連通路を閉鎖する閉鎖具はねじ手段を介してキャップ30に連結され、キャップ30の回転操作により閉鎖部材は開放状態される。閉鎖具を構成する弁部材40は上下の隔室を分離す弱シール部10Bに近接位置し、薬剤容器開放のための操作は剥離可能溶着部を強制的に剥離せしめ得るべく弁部材40を位置(40´)させる。【選択図】 図2
