PROBLEM TO BE SOLVED: To provide a chemical mixed injection instrument in a new structure, which allows puncture to a rubber stopper of a puncture needle in a state where a port part of a vial is accurately positioned so as to spread in an axis perpendicular direction to the puncture needle.SOLUTION: A chemical mixed injection instrument includes: a positioning means for positioning and holding a flange-like port part 92 of a vial 86 so as to spread in the axis perpendicular direction of a vial guide member 14; and a slide movement blocking means for blocking axial direction inward movement in which the vial guide member 14 approaches a partition wall 18 and then holding the vial 86 in the state of being isolated from a puncture needle 24 until the port part 92 of the vial 86 is positioned and held by the vial guide member 14. After the port part 92 of the vial 86 is positioned and held by the vial guide member 14, movement block by the slide movement blocking means is canceled, the axial direction inward movement of the vial guide member 14 is allowed, and the puncture with the puncture needle 24 is performed to the vial 86. |
