[Problems] The injection needle while preventing coring of the rubber plug of the container to provide a mixed injection device capable of multiple puncturing the rubber plug. A mixed injection apparatus, executes the mixed injection process comprising a suction step for sucking liquid from the vessel using an implantation step and the syringe to inject the liquid using a syringe into a container in which the rubber plug is inserted into the mouth portion a mixed injection processing unit for, and a control unit for controlling the mixed injection processing unit, a rubber stopper of said container, a cylindrical insertion portion to be inserted into the mouth portion of the container, the edge of the mouth portion of the container at least a portion and a contact portion for contacting said control unit, said injection in step and the suction step, the first piercing method of inserting an injection needle of the syringe into the container and passed through the insertion portion When, it is possible to select a second puncture wherein said by the syringe needle to penetrate the region corresponding to the cylindrical inside of the insertion portion is inserted into the container.FIELD 39A【課題】容器のゴム栓のコアリングを防止しつつ注射針をゴム栓に複数回穿刺することが可能な混注装置を提供すること。【解決手段】混注装置は、口部にゴム栓が挿入された容器に注射器を用いて液体を注入する注入工程及び前記注射器を用いて前記容器から液体を吸引する吸引工程を含む混注処理を実行する混注処理部と、前記混注処理部を制御する制御部とを備え、前記容器のゴム栓が、前記容器の口部に挿入される円筒状の挿入部と、前記容器の口部の縁部に少なくとも一部が接触する接触部とを含み、前記制御部が、前記注入工程及び前記吸引工程において、前記注射器の注射針を前記挿入部に貫通させて前記容器内に挿入する第1穿刺方法と、前記注射器の注射針を前記挿入部の円筒内部に対応する領域に貫通させて前記容器内に挿入する第2穿刺方法とを選択可能である。【選択図】図39A
