PROBLEM TO BE SOLVED: To provide a medical multi-chamber container capable of assuring administration of medicines to a patient after the medicines each stored in each storage chamber are surely mixed, and capable of surely preventing an accidental trouble by mistake of the administration of the medicines to the patient before the medicines are mixed.SOLUTION: The medical multi-chamber container 1 includes: the first and second storage chambers 10, 11 a partition weak seal part 20 for partitioning both the chambers 10, 11 a medicine discharge outlet 32 connected to the second storage chamber 11 and a discharge weak seal part 21 for partitioning off the medicine discharge outlet 32 from the second storage chamber. The liquid medicine is stored in at least one of both the storage chambers 10, 11. The partition weak seal part 20 and the discharge weak seal part 21 are opened by raising the pressure of both the storage chambers 10, 11. The pressure required to open the discharge weak seal part 21 is higher than the pressure required to open the partition weak seal part 20.COPYRIGHT: (C)2011,JPO&INPIT【課題】確実に各収納部に収納されている薬剤を混合した後に患者に投与することを保証し、誤って薬剤を混合しないで患者に投与する事故を確実に防止し得る医療用複室容器を提供する。【解決手段】第1及び第2収納部10,11と、両収納部10,11を仕切る仕切り用弱シール部20と、第2収納部11に接続された薬剤排出口32と、第2収納部と薬剤排出口32との間を仕切る排出用弱シール部21とを備え、両収納部10,11の少なくとも1つに液状薬剤が収納され、仕切り用弱シール部20及び排出用弱シール部21は両収納部10,11内の圧力を高めることにより開封するとともに、排出用弱シール部21を開封するために必要な圧力が、仕切り用弱シール部20を開封するために必要な圧力より大きいことを特徴とする医療用複室容器1。【選択図】図1
