Puncture needle box and puncture device for its installation

The puncture needle case (4) has a lancet body (5) and a lancet case (6). The lancet main body (5) has a puncture needle (10), a connecting portion (7) disposed on the second end side and used for connecting with the puncture device (1), and a top end portion of the puncture needle (10) before use. The puncture needle cover part (8), the breaking part (9) that breaks to separate the puncture needle cover part (8) to expose the tip part of the puncture needle (10) when the puncture is performed, and the puncture needle cover part (8) The guide protrusion (12) on the outer peripheral surface is closer to the first end side of the breaking portion (9), and the sliding protrusion (13) is arranged on the second end side than the breaking portion (9). The lancet case (6) has a helical guide portion (14) that applies force to the lancet case (6) in a predetermined direction when it moves relatively in the piercing direction while engaging with the guide protrusion (12). The rotational force; the sliding groove (15), which guides the movement of the lancet case (6) in the piercing direction in the state of engaging with the sliding protrusion (13). The lancet case (6) is attached to the outer periphery of the middle part of the lancet main body (5) in a state where the fracture part (9) is not broken. The puncture needle cover part (8) also has a stopper (33) that restricts the sliding of the lancet case (6) from the state mounted on the middle part to the second end side.
