【発明の詳細な説明】
（産業上の利用分野）
本発明は、血管に薬液や血液を注入したり、血液を採取
するために用いる注射針に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an injection needle used for injecting a drug solution or blood into a blood vessel or for collecting blood.
（従来の技術）
一般に、注射針の先端を血管に挿入することは、必ずし
も容易なことではない。血管自体を目視することが難し
い場合、血管の位置を把握することが難しい場合などが
あるためである。(Prior Art) Generally, it is not always easy to insert the tip of an injection needle into a blood vessel. This is because there are cases where it is difficult to visually observe the blood vessels themselves, and cases where it is difficult to grasp the position of the blood vessels.
従来は、注射器の針先の空気を抜いて肉体に少し挿入し
た後、注射器のピストンを僅かに引いて針流路に陰圧を
負荷し、この状態を保持しながら、さらに挿入して血管
を探り、血液が注射器内に流入することを目視すること
により、注射針の先端が血管に達したことを確認してい
た。この操作を適確迅速に行うためには、相当の熟練を
必要とする。操作が適切に行えないと、注射針の挿し直
すことになり、必要以上の苦痛を与えることになる。Conventionally, after removing the air from the needle tip of a syringe and inserting it into the body a little, the piston of the syringe is pulled slightly to apply negative pressure to the needle flow path, and while this state is maintained, the needle is further inserted to open the blood vessel. It was confirmed that the tip of the syringe needle had reached the blood vessel by probing and visually observing that blood flowed into the syringe. Considerable skill is required to perform this operation accurately and quickly. If the procedure is not performed properly, the needle must be reinserted, causing unnecessary pain.
（発明が解決しようとする課題）
本発明は、上記の問題点を解消し、針先への陰圧を片手
で簡単に保持しながら、血管を容易に探すことができる
血管注射針を提供しようとするものである。(Problems to be Solved by the Invention) The present invention aims to solve the above-mentioned problems and provide a vascular injection needle that can easily search for blood vessels while easily maintaining negative pressure to the needle tip with one hand. That is.
（課題を解決するための手段）
本発明は、注射針の針元又は針の中間に球状弾性体を付
設し、弾性体内と針の流路とを連通させる連通孔を設け
たことを特徴とする血管注射針である。(Means for Solving the Problems) The present invention is characterized in that a spherical elastic body is attached to the base of the injection needle or in the middle of the needle, and a communication hole is provided to communicate the elastic body and the flow path of the needle. This is a vascular injection needle.

成するときには、透明弾性体内への１ｍ液の流入を目視
できるので、容易に確認することができる。FIG. 1 is a sectional view of an injection needle that can be attached to and detached from a syringe. This injection needle has a hemispherical elastic body integrally attached to the base of the injection needle for applying pressure relief. The procedure for use is to first remove the air from the needle tip, then insert the tip of the injection needle into the body with the elastic body crushed, and apply a relieved pressure to the needle flow path. After insertion, the pressure relief is maintained even if you remove your hand from the elastic body. When the injection needle is further inserted and the needle tip reaches the blood vessel, blood flows out into the syringe due to pressure relief, so it can be confirmed that the needle tip has reached the blood vessel. Note that when the elastic body is made of a transparent material, the inflow of 1 m of liquid into the transparent elastic body can be visually observed, so it can be easily confirmed.

、点滴などを開始する。FIGS. 2(a) and 2(b) are conceptual diagrams of a syringe needle used when time is required, such as infusion or blood transfusion. (a) is a side sectional view, and (b) is a plan view. After the needle tip is inserted into a blood vessel, a support plate is attached to the middle of the needle to fix the needle to the body using adhesive tape or the like. A hemispherical transparent elastic body is attached to the upper surface of this support plate and communicated with the elastic body through the communication hole of the injection needle. The procedure for use is
Perform the same procedure as for the injection needle in Figure 1. After confirming that the tip of the injection needle has reached the blood vessel by the flow of blood into the transparent elastic body on the support plate, fix the support plate to the skin with tape. Then, start intravenous drip, etc.
