Description
【０００１】
【産業上の利用分野】
本発明は医療現場で安全に取扱いできる注射針に関する。
【０００２】
【従来の技術】
注射器本体に着脱自在な注射針は、全体が筒状のキャップに収納された状態で提供されているが、使用後該キャップを被せるまでの間が注射針先端を露出することになり、危険な一瞬と成る。
【０００３】
【発明が解決しようとする課題】
本発明は使用後の注射針を安全に廃棄処理できる注射針を提供するものである。
【０００４】
【課題を解決するための手段】
本発明の注射針は、注射器本体の先端部射出口に気密状に嵌合する受口を針本体の基部に接合して成る注射針において、針本体の前記基部側の後端部に折曲自在なチューブの後端部を外嵌接着し、中間部を所要長さに渡って針本体から離脱させ、チューブの先端部を針本体の先端を収蔵する長さに渡って該針本体の先端部に外嵌案内し、前記中間部の外面にその厚みの左右方向に折曲自在なツマミを配設して成る。
【０００５】
【作用】
注射針の使用時には、ツマミを引き上げることによってチューブの先端が針本体の基部側へ移動して該針本体の先端を露出し、使用後はツマミを押し下げることによって瞬時に針本体の先端をチューブ内に収蔵する。
【０００６】
【実施例】
本発明を一実施例により説明すると、図１に示すように、横向き凹状の嵌合部１を有する受口２を針本体３の基部に接合して成る注射針において、針本体３の前記基部側の後端部に折曲自在なチューブ４の後端部を外嵌接着し、中間部５を所要長さ（チューブ４の先端部６の先端から針本体３の先端を十分に露出するに足る該先端部６の引き上げ長さ）に渡って針本体３から離脱させ、チューブ４の先端部６を針本体３の先端を収蔵する長さに渡って該針本体３の先端部に外嵌案内し、該チューブ４の中間部５の外面にその厚みの左右方向に折曲自在なツマミ７を配設して成る。
【０００７】
このようにして成る注射針ａは、図２に示すように注射器本体８の射出口９を受口２の嵌合部１に気密状に嵌合し、ツマミ７をつまんで引き上げることによって中間部５が折曲変形し、針本体３の先端を露出して使用されるものであり、使用後はツマミ７を押し下げるだけで、図１に示す状態となり、針本体３に一切触れることなく、しかも瞬時に該針本体３の針先をチューブ４内に収蔵でき、その状態で図３に示すようにキャップ１０に収納できるから、極めて安全に廃棄処理できるものである。
【０００８】
【発明の効果】
以上のように本発明の注射針によれば、ツマミをつまんで引き上げることによってチューブの先端が針本体の基部側へ移動して該針本体の先端を露出し、使用後はツマミを押し下げるだけで、瞬時に針先をチューブ内に収蔵できるから、キャップを被蓋するまでに不注意で指先に針先を突き刺したり、血液に触れることがないから、極めて安全に廃棄処理できる効果がある。
【図面の簡単な説明】
【図１】本発明に係わる注射針ａの一側面図である。
【図２】該注射針ａの使用状態の説明図である。
【図３】該注射針ａの廃棄状態の説明図である。

[Industrial applications]
The present invention relates to an injection needle that can be safely handled at a medical site.
[0002]
[Prior art]
The injection needle which is detachable from the syringe body is provided in a state of being entirely housed in a cylindrical cap, but the tip of the injection needle is exposed until the cap is put on after use, which is dangerous. It will be a moment.
[0003]
[Problems to be solved by the invention]
The present invention provides an injection needle that can safely dispose of a used injection needle.
[0004]
[Means for Solving the Problems]
An injection needle according to the present invention is an injection needle comprising a receptacle, which is fitted in an airtight manner at a distal end outlet of a syringe main body, joined to a base of the needle main body. The rear end of the flexible tube is externally fitted and adhered, the intermediate portion is separated from the needle body over a required length, and the distal end of the tube is extended over the length for storing the distal end of the needle body. A knob is provided on the outer surface of the intermediate portion so as to be able to bend in the left-right direction .
[0005]
[Action]
When using the injection needle, the tip of the tube moves to the base side of the needle body by pulling up the knob to expose the tip of the needle body. After use, the tip of the needle body is instantaneously pushed down by pushing down the knob. To be stored.
[0006]
【Example】
The present invention will be described with reference to an embodiment. As shown in FIG. 1, in the injection needle formed by joining a
[0007]
As shown in FIG. 2, the injection needle a thus constructed is fitted in an airtight manner with the injection port 9 of the syringe body 8 into the fitting portion 1 of the
[0008]
【The invention's effect】
As described above, according to the injection needle of the present invention, the tip of the tube moves toward the base side of the needle body by pinching and pulling the knob to expose the tip of the needle body , and after use, it is only necessary to push down the knob. Since the needle tip can be stored in the tube instantaneously, there is no need to inadvertently pierce the needle tip or touch the blood until the cap is covered.
[Brief description of the drawings]
FIG. 1 is a side view of an injection needle a according to the present invention.
FIG. 2 is an explanatory view of a use state of the injection needle a.
FIG. 3 is an explanatory view of a discarded state of the injection needle a.
