摘要:
A resin hollow needle includes a distal end section including a puncture end portion, a large-diameter section having a diameter greater than that of the distal end section, a tapered section that is located between the large-diameter section and the distal end section, and a hub section. The distal end section includes a hole that is provided on a proximal end side in comparison to a distal end and on a distal end side of the tapered section, and communicates with the inside and the outside of a hollow needle, and a tapered puncture end portion. The distal end section has a total length of 7 to 14 mm and a maximum outer diameter of 1.5 to 3.0 mm. The tapered section has a length of 0.3 to 4.7 mm and a taper angle of 10° to 50°. The large-diameter section has a length of 4 mm or greater, and a distal end outer diameter that is greater than the maximum outer diameter of the distal end section by 0.6 to 3.0 mm.
