Description

【発明の詳細な説明】 本発明は医薬液を移送させる医療用ビン針に属する。[Detailed description of the invention] The present invention relates to a medical bottle needle for transferring medical liquid.

中じきりパイプは二通路を有したピン針に関し、従来に
ない新しい構造と作用効果を有するものである。本発明
の詳細を説明して、従来にない特徴を述べる。The saddle-pierced pipe is a pin needle with two passages, and has a new structure and operation effects that have never existed before. The present invention will now be described in detail and its non-conventional features set forth.

ある。FIG. 1 is a shape diagram of the tip portion of a pipe according to an embodiment of the present invention, FIG. 2 is a front view, and FIG. 3 is a side view. 1 is a pipe, 2 is a bored plate, and 2a has a tip portion processed into the shape of a cutting edge to indicate a puncture portion.

本発明では中じきり板の先端部をパイプの外に露呈させ

し易い様に刃先を形成させてあるところに特徴を有する
ものである。When the purpose was to transfer a medicinal solution by piercing a pipe-shaped needle, conventionally the pipe was formed with a cutting edge.
The present invention is characterized in that the leading end of the saddle board is exposed outside the pipe, and the cutting edge is formed to eliminate the following inconvenience and facilitate use. .

従来のパイプに刃先を有したのでは、刃先のアゴバリに

バリを取る工程を加えているのが現状である。本発明で
は刃先部分２ａは薄い板である中じきり板２の先に刃を
形成するだけであるから刃付け加工は簡便である。When conventional pipes have cutting edges, accidents such as cutting off the outer skin of the part that is suitable for piercing due to the jaws of the cutting edge often occur. Furthermore, the generation of jaw burrs is unavoidable when forming the cutting edge of a pipe, and the current situation is that a step to remove the jaw burrs is added in a later process. In the present invention, the cutting edge portion 2a is simply formed by forming a cutting edge at the tip of the hollow plate 2, which is a thin plate, so that the cutting process is simple.

またパイプ１の先の部分ｌａのところを面取るか、また

工法の注射針状の刃先（図示せず）を形成させるための
手間と欠陥を省き、刃付け加工が簡便にして効果的に可
能である中じきり板に刃先２ａを形成して中じきりパイ
プ１を製造する。Further, by chamfering or squeezing the tip portion la of the pipe 1 to reduce friction, it can be shaped to be easily penetrated. The present invention eliminates the trouble and defects required to form a needle-like cutting edge (not shown) in the conventional method on a pipe-shaped piece, and provides a saddle-bored board that allows the cutting process to be performed simply and effectively. A cutting edge 2a is formed to manufacture the hollow pipe 1.

かかる工法による刃先によって前記した不都合の排除の
目的を達成し得るものである。The purpose of eliminating the above-mentioned inconveniences can be achieved by using a cutting edge produced by such a construction method.
