Abstract: A blood sampling device (10) configuring a blood bag system (12) includes: a hollow needle (80) that can penetrate through a rubber plug (202) of a blood sampling tube (200) inserted into a blood sampling holder (78); a hub (76) that includes a needle supporting unit (90) for supporting a base end side of the hollow needle (80) and to which the blood sampling holder (78) is rotatably attached; a needle cover (82) made of rubber that is externally fitted to the needle supporting unit (90) while covering a tip side of the hollow needle (80); and a cap (84) arranged on the needle supporting unit (90) in such a manner that the cap (84) can come into contact with the needle cover (82) and is independent of the blood sampling holder (78).

Abstract: A protector includes an outer tube and an inner tube. The outer tube includes an outer tube main body including an outer tube lumen for housing a puncture device, a holding part for holding a hub, and an extended part extended from the holding part. The inner tube includes an inner tube main body and a lumen inclined part. The inner tube main body is held in a proximal end side of the outer tube lumen and is movable in a proximal end direction of the outer tube lumen. The inner tube main body includes an inner tube lumen into which a tube is inserted. By moving the inner tube in a distal end direction, the inner surface of the lumen inclined part is abutted against the extended part, and the extended part is biased by the lumen inclined part in a direction in which a diameter of the tube is reduced.

Abstract: An initial flow blood bag (10) that configures a blood bag system (12) includes a bag body (80) that is formed of a soft material in a bag-shaped manner, and can house initial flow blood. The bag body (80) includes a first housing portion (84) provided with a blood inflow portion (82), a second housing portion (92) provided with a blood outflow portion (94), and a communication path (90) configured from partitions (86, 88) that partition an inside of the bag body (80) into the first housing portion (84) and the second housing portion (92), and allowing the first housing portion (84) and the second housing portion (92) to communicate with each other.

Abstract: A protector (1) is used by being attached to a puncture device (50). The protector (1) includes an outer tube (2) and an inner tube (9). The outer tube (2) includes an outer tube main body (3) including an outer tube lumen (4) for housing the puncture device (50), a holding part (5) for holding a hub (52), and an extended part (8) extended from the holding part (5) in a proximal end direction. The inner tube (9) includes an inner tube main body (10) and a lumen inclined part (12). The inner tube main body (10) is held in a proximal end side of the outer tube lumen (4) and movable in a proximal end direction of the outer tube lumen (4). The inner tube main body (10) includes an inner tube lumen (11) into which a tube (53) is inserted. In the lumen inclined part (12), an inner diameter of the inner tube lumen (11) gradually increases toward a distal end side of the inner tube main body (10).
