Therefore, it is possible to prevent medical personnel and the like from accidentally puncturing with the hollow needle 2 protruding from the tip of the gutter-shaped member 6.
- the branch 14 a is disposed in the gutter-shaped member 6 in front of the cutting edge of the hollow needle 2.
- the gutter-shaped member 6 has the opening surface above the rack 4 and the opening at the distal end serving as a path from which the hollow needle 2 projects, which is closed by the L-shaped handle 14. It is possible to reliably prevent a finger of a medical staff from touching the hollow needle 2 contaminated with blood or the like. Further, the branch portion 14a can reliably prevent the hollow needle 2 from protruding again from the tip of the gutter-shaped member 6.
- the protrusion 12 e provided on the side surface of the front end of the rack 4 becomes the inner surface of the side wall at the rear end of the gutter-shaped member 6. It is locked by the provided projection 1 2 f. For this reason, it is possible to prevent the hollow tube 2 accommodated in the gutter-shaped member 6 from further retreating and dropping from the gutter-shaped member 6.
- a means capable of maintaining the combined state of the rack 4 and the gear 8 when the hollow needle 2 is accommodated in the gutter-shaped member 6. May be provided.
- the first aspect of the protrusion maintaining means and the second aspect of the accommodation and maintaining means may be combined.
- the second aspect of the protrusion maintaining means may be combined with the first aspect of the storage and maintaining means, which may be used industrially.
