（２）気密に結合できるので、外気による混注部からの
汚染を完全に防止できる。(2) Since airtight coupling is possible, it is possible to completely prevent contamination from the mixed injection part by the outside air.
（３）押さえ部材の外壁に雄ネジを設けているので、被

強固に接続することができる。(3) Since the male screw is provided on the outer wall of the pressing member, it is possible to adopt an infusion line in which the cup-shaped coupling means having the female screw on the inner wall is rotatably attached to the hub of the puncture needle as the object to be connected. it can. Therefore, when the infusion line is connected to the connecting part, the puncture needle does not rotate in the rubber plug of the connecting part, so that both can be firmly connected without core ring.
