PROBLEM TO BE SOLVED: To provide a mixer for mixing a medical agent and a mixture liquid which blocks the medical agent within a closed space even when the medical agent leaks or volatilizes from a vessel, and prevents exposure of the medical agent from extending outward.SOLUTION: A mixer 1 mixes a medical agent stored in at least one medical agent vessel 50 and a mixture liquid stored in at least one mixture liquid vessel 60 using a syringe, and includes: a body part 10 having a closed space S1 a syringe-holding part 20 by which a communication part and the closed space can communicate with each other a medical agent vessel-holding part 30 capable of holding the medical agent vessel while the insides of the medical agent vessel and the closed space can communicate with each other and a mixture liquid vessel-holding part 40 capable of holding the mixture liquid vessel at the outside of the closed space while the inside of the mixture liquid vessel and the closed space can communicate with each other. The syringe-holding part can hold the syringe while the communication part is relatively movable in the closed space with respect to the insides of the medical agent vessel and the mixture liquid vessel so that the communication part communicates with the insides of the medical agent vessel and the mixture liquid vessel after the communication part communicates with the closed space.COPYRIGHT: (C)2014,JPO&INPIT【課題】容器から薬剤が漏れたり揮発した場合でもそれを閉鎖空間内にとどめ、外部に曝露が及ばなくする薬剤及び混合液の混合装置を提供する。【解決手段】混合装置1は、シリンジを用いて、1以上の薬剤容器50に収容された薬剤と1以上の混合液容器60に収容された混合液との混合を行う混合装置であって、閉鎖空間S1を有する本体部10と、流通部と閉鎖空間とを連通可能な状態で、シリンジ保持部20と、薬剤容器の内部と閉鎖空間とを連通可能な状態で、薬剤容器を保持可能な薬剤容器保持部30と、混合液容器の内部と閉鎖空間とを連通可能な状態で、混合液容器を閉鎖空間の外部において保持可能な混合液容器保持部40とを備え、シリンジ保持部は、流通部が閉鎖空間と連通した後、流通部が薬剤容器及び混合液容器の内部と連通するように、流通部が閉鎖空間内を薬剤容器及び混合液容器の内部に対し相対的に移動可能な状態で、シリンジを保持可能である。【選択図】図1
