A blood-flow-path switching device and a blood-bag system, wherein: a tube-shaped body (68) has a body tube (69) for extending in the axial direction thereof, and a branching tube (71) for branching and extending from the axial direction; and the interior of a hollow section (69c) of the body tube (69) is provided with a blocking part (74). A connecting part (70) capable of moving in the axial direction is positioned in the hollow section (69c). By moving the connecting part (70) in the pushing direction and creating an opening by penetrating the blocking part (74), the connection between a first port (86) and a third port (90) is blocked, and the first port (86) and a second port (88) are connected. |
