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

Blood sampling device and blood bag system

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.
