Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an injection needle having a pointed end part that includes an inclined portion with a tip hole in which the pointed end part is formed with a resin having predetermined hardness, a long-torsoed part continuing to the pointed end part is formed with a soft resin so as to be freely bendable, and predetermined colors are provided for identification; and a method for manufacturing the injection needle.SOLUTION: An injection needle 1 comprises: a base part 2 to be mounted on a syringe body; a slender cylindrical torsoed part 3 extending from the base part 2; a pointed end part 4 positioned at the distal end of the torsoed part 3 so as to be inclined toward the distal end; a tip hole 5 opened at an inclined side surface of the pointed end part 4; and a through hole 6 communicating with the tip hole 5 through the base part 2 and the torsoed part 3. The pointed end part 4 is formed with a resin high in hardness and colored with a predetermined color. The torsoed part 3 is formed with a colored resin having a strong bending moment.SELECTED DRAWING: Figure 1
【課題】 本発明は、先端孔が尖端部の傾斜部分に形成される注射針において、尖端部が所定の硬度を有する樹脂で形成されると共に、尖端部に続く胴長部が柔らかい樹脂で形成されて屈曲自在であり、且つ識別可能にするために所定の色彩を有する注射針及び注射針の製造方法を提供する。【解決手段】 本発明は、注射器本体に装着されるための基部2と、該基部2から延出する細長円筒状胴長部3と、該胴長部3の先端に位置し、先端に向けて傾斜する尖端部4と、該尖端部4の傾斜する側面に開口する先端孔5と、前記基部2及び前記胴長部3とを貫通して先端孔5に至る貫通孔6とを具備する注射針1において、前記尖端部4は、硬度の高く、所定の色彩に彩色された樹脂によって形成されると共に、前記胴長部3は曲げモーメントの強い彩色された樹脂によって形成されることにある。【選択図】 図1 |
