PROBLEM TO BE SOLVED: To provide a method of preliminarily combining chemicals desired to be simultaneously dosed with an infusion such as electrolyte solution, amino acid infusion, and glucose.SOLUTION: In an infusion container 16 with a plurality of separate rooms 8, 9 divided by a communicable isolation means 1, the infusion 13 is injected into the separate room 8 and a discharge region 2 is arranged therein, and the separate room 9 is equipped with an injection region 4 but is a vacant room. The chemical desired to be administered simultaneously with the infusion is injected into the vacant room through the injection region to preliminarily prepare the chemical. Accordingly, the chemical is preliminarily dosed in an dispensary room etc. and then delivered to a patients room or a patients home and then both chemicals can be mixed while the both rooms are made to communicate with each other by releasing the isolation means at the patients room or home and administered.COPYRIGHT: (C)2009,JPO&INPIT【課題】電解質液、アミノ酸輸液、ブドウ糖輸液等の輸液に、輸液と同時に投与したい薬剤を予め組み合わせて予備調整する方法を提供する。【解決手段】連通可能な隔離手段1で区切られた複数の分室8,9を備えた輸液容器16において、分室8には輸液13が注入されておりそして排出部位2を備えており、分室9は注入部位4を備えているが空室となっている。この空室に輸液と同時に投与したい薬剤を注入部位から注入して予備的に薬剤を調製する。このことにより、予め調剤室等で予備調剤した後各病室または在宅患者宅に配達し、各病室または在宅患者宅で隔離手段を連通して両薬剤を混合して投与することが可能となる。【選択図】図2
