Description

【０００１】
【産業上の利用分野】
この発明は注射の際の痛みを軽減するため、針の先に曲げを持たせ刃先を鋭利にした注射針（先端部）に関するものである。
【０００２】
【従来の技術】
従来の注射針は、管を斜めに切った竹槍の様な形状なので、刃先の角度（９）を鋭くすると、口（１）が楕円状に大きくなった。
【０００３】
【発明が解決しようとする課題】
管を斜めに切った形状では、刃先の角度（９）を鋭くするのに限界があった。本発明は、この欠点を解決するためになされたものである。
【０００４】
【課題を解決するための手段】
管に曲げ部ａ（３）と曲げ部ｂ（４）を持たせ、刃面（５）を作る。本発明は以上の構成よりなる。
【０００５】
【作用】
本発明は、曲げ部ｂ（４）から針頂点（２）にかけて、刃先の角度（９）が鋭くなっていることで、注射を刺すときの痛みの軽減がはかれる。
【０００６】
【実施例】
以下、本発明の実施例をのべる。
（イ）管に曲げ部ａ（３）と曲げ部ｂ（３）を持たせ、刃面（５）を作る。
（ロ）刃面の管内側（６）の鋭利な部分は、丸みもしくは面取り加工する。
本発明は、以上の構成よりなっている。
なお針頂点（２）の位置は、第５図に示すようにある程度まで下げても、効果は少なくなるが、有効である。
【０００７】
【発明の効果】
本発明を使用することによって、注射時の痛みを軽減できる。

[Industrial applications]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an injection needle (tip) having a sharp beveled tip to reduce pain at the time of injection.
[0002]
[Prior art]
The conventional injection needle has a shape like a bamboo spear with a tube cut obliquely, and therefore, when the angle (9) of the cutting edge is sharpened, the mouth (1) becomes elliptical.
[0003]
[Problems to be solved by the invention]
In the case where the pipe is cut obliquely, there is a limit to sharpening the angle (9) of the cutting edge. The present invention has been made to solve this drawback.
[0004]
[Means for Solving the Problems]
The pipe is provided with a bent portion a (3) and a bent portion b (4) to form a blade surface (5). The present invention has the above configuration.
[0005]
[Action]
In the present invention, since the angle (9) of the cutting edge is sharp from the bent portion b (4) to the needle vertex (2), pain at the time of piercing an injection can be reduced.
[0006]
【Example】
Hereinafter, examples of the present invention will be described.
(A) The pipe has a bent portion a (3) and a bent portion b (3) to form a blade surface (5).
(B) The sharp portion inside the pipe (6) of the blade surface is rounded or chamfered.
The present invention has the above configuration.
It should be noted that even if the position of the needle vertex (2) is lowered to some extent as shown in FIG.
[0007]
【The invention's effect】
By using the present invention, pain upon injection can be reduced.
[Brief description of the drawings]
1 is a perspective view of the tip of the injection needle of the present invention; FIG. 2 is a side sectional view of the tip of the injection needle of the present invention; FIG. 3 is a front view of the tip of the injection needle of the present invention; FIG. 5 is a side view showing a positional relationship between a blade surface and a bent portion of a tube. FIG. 5 is a side sectional view showing an embodiment of a tip portion of the injection needle of the present invention.
