PROBLEM TO BE SOLVED: To simplify a process of sealing a container after being filled with a medical solution by eliminating a process of blocking up an extraction port 40 with a stopper after being filled with the medical solution to overcome the complication of a mechanism in a medical solution filling machine, in manufacture of a medical solution enclosure for medical application, in which a medical solution is enclosed in a flexible container with the extraction port.SOLUTION: A medical solution enclosure 20 for medical application is manufactured according to this method including: a process of forming a filling port communicating a medical solution storing chamber with the outside by cutting off the respective projected bonding portions of a first chamber 18 and a second chamber 19 constituting the medical solution storing chamber at the same time a process of separately filling the medical solution storing room with a medical solution through the respective filling ports of the first chamber 18 and the second chamber 19 and a process of simultaneously or separately adhesively bonding resin films of a predetermined range in the periphery of each filling port of the first chamber 18 and the second chamber 19 to put the medical solution storing chamber in the closed state.COPYRIGHT: (C)2010,JPO&INPIT【課題】注出口を備える可撓性容器に医療用薬液を封入した医療用薬液封入物の製造において、薬液充填後に注出口40を栓により閉塞する工程を無くし、薬液充填機の機構の複雑化を解消し、薬液充填後の容器の密閉工程を簡単化する。【解決手段】薬液収容室を構成する第1室18及び第2室19のそれぞれの突出した接着部分を同時に切除して薬液収容室と外部を連通する充填口を形成する工程、第1室18及び第2室19のそれぞれの充填口を介し薬液収容室へ薬液を別々に充填する工程、及び第1室18及び第2室19のそれぞれの充填口のまわりの所定範囲の樹脂フイルムを同時又は別々に接着し薬液収容室を密閉状態とする工程により医療用薬液封入物20を製造する。【選択図】図5
