    • When a hub (40) is in an initial position at which it is located on the front end side of an inner cavity of a shield (20), an inner needle (50) penetrates an outer needle (30) and protrudes from a leading end of the outer needle to the outside, and when the hub is in a retracted position at which it is located on the rear end side of the inner cavity of the shield, the inner needle is housed within the inner cavity of the shield. A first side hole (31) is formed in an outer circumferential face of the outer needle, and a second side hole (51) is formed in an outer circumferential face of the inner needle. When the hub is in the initial position, an inner circumferential face of a region (33) of the outer needle that contains the first side hole is in close contact with the outer circumferential face of the inner needle, and the second side hole is located closer to the hub than the region where the inner circumferential face of the outer needle is in close contact with the outer circumferential face of the inner needle. Thus, a priming operation for filling a gap between the inner needle and the outer needle with blood can be easily performed, and leakage of blood through the side hole of the outer needle during puncture does not occur.
    • 当轮毂(40)位于其位于护罩(20)的内腔的前端侧的初始位置时,内针(50)穿过外针(30)并从前端 外针的端部到外部,并且当轮毂处于其位于护罩的内腔的后端侧的缩回位置时,内针容纳在护罩的内腔内。 在外针的外周面形成有第一侧孔(31),在内针的外周面形成有第二侧孔(51)。 当轮毂处于初始位置时,包含第一侧孔的外针的区域(33)的内周面与内针的外周面紧密接触,第二侧孔位于 比外针的内周面与内针的外周面紧密接触的区域更靠近轮毂。 因此,可以容易地进行用于用血液填充内针和外针之间的间隙的起动操作,并且不会在穿刺期间通过外针的侧孔泄漏血液。
