PROBLEM TO BE SOLVED: To provide a medicine administration appliance capable of preventing administration in a state where a medicine is not added by obtaining an administration possible state after the inside of a prefilled syringe communicates with the inside of a medicine container.SOLUTION: The medicine administration appliance 1 includes: the prefilled syringe 2 whose distal end is sealed by a seal part 16 the medicine container 4 having a sealing member 42 and a communication member 3 having an outer cylinder side puncture part 53 for puncturing the seal part and a medicine container side puncture part 54 for puncturing the sealing member 42. The sealing member 42 includes a medicine administration member mounting part 44 which is extended into a container body 41 and on which a medicine administration member is mounted. The medicine administration member mounting part 44 on which a syringe needle can be mounted is exposed in the medicine administration appliance 1 by releasing the fixing of the sealing member 42 and the container body in a state where the outer cylinder side puncture part 53 punctures the seal part 16 and the medicine container side puncture part 54 punctures the sealing member 42.COPYRIGHT: (C)2012,JPO&INPIT【課題】 プレフィルドシリンジ内と薬剤容器内とを連通した後に、投与可能状態となり、薬剤が添加されない状態での投与を防止できる薬剤投与具を提供する。【解決手段】薬剤投与具1は、先端部がシール部16により封止されたプレフィルドシリンジ2と、封止部材42を有する薬剤容器4と、シール部を刺通可能な外筒側穿刺部53と封止部材42を刺通可能な薬剤容器側穿刺部54とを有する連通部材3とからなる。封止部材42は、容器本体41内に延び、かつ、薬剤投与部材を装着可能な薬剤投与部材装着部44を備える。薬剤投与具1は、外筒側穿刺部53がシール部16を刺通し、薬剤容器側穿刺部54が封止部材42を刺通した状態にて、封止部材と容器本体との固定を解除することにより、注射針が装着可能な薬剤投与部材装着部44が露出する。【選択図】図2
