    • PROBLEM TO BE SOLVED: To simply and infallibly cover a used needle and to prevent blood from leaking out of an opening of a protector. SOLUTION: The protector 16 has an inner tube 18, a lid 38 connected to an upper opening 34 of the inner tube 18 through a hinge 36, and an outer tube 20 to hold the inner tube 18 in its inner cavity. A blood collecting needle 14 with which a tube 12 is connected can be contained in the inner tube 18. The inner tube 18 is provided with a circular flange 32 to be seated on a proximal end part 28 of a hub 22 integrated with the blood collecting needle 14 when the blood collecting needle 14 moves downward. An operation lever 44 extending downward, whose end part 46 protrudes outward slightly, is provided on a side surface of the lid 38. When the blood collecting needle 14 moves, the inner tube 18 and the tube 12 are integrally drawn by the circular flange 32 to slide relative to the outer tube 20, the end part 46 abuts on a lower end part 70a of an operation hole 70 to close the lid 38, and the blood collecting needle 14 can be contained in the inner tube 18.
