PROBLEM TO BE SOLVED: To provide a mixed injection management apparatus, a mixed injection apparatus, and a mixed injection management program which may support efficient use of medicine in a medicine container in which a specified volume of medicine is stored.SOLUTION: A mixed injection management apparatus determines whether medicine remains in a medicine container used in a mixed injection process where a medicine indicated in preparation data is injected from one or more medicine containers storing a specified volume of the medicine into a transfusion container, and make display means to preferentially display preparation data among selectable candidates of the preparation data as a target of the mixed injection process, in which the displayed preparation data of a prescription medicine contains the same type medicine with the remaining medicine determined as remaining in the medicine container in a foregoing mixed injection process.SELECTED DRAWING: Figure 22【課題】既定量の薬剤が収容された薬剤容器内の前記薬剤の効率的な使用を支援することのできる混注管理装置、混注装置、及び混注管理プログラムを提供すること。【解決手段】混注管理装置は、調製データに示された薬剤を既定量の前記薬剤が収容された一又は複数の薬剤容器から輸液容器に注入する混注処理で使用される前記薬剤容器に前記薬剤が残存するか否かを判断し、前記混注処理の対象となる前記調製データの選択候補のうち過去の前記混注処理で前記薬剤容器に残存すると判断された残存薬剤と同種の薬剤を処方薬に含む調製データを優先的に表示手段に表示させる。【選択図】図22
