Abstract
【解決手段】皮膚表面の表皮12に薬液を注入する針本体の少なくとも先端部分が、延出方向に向かって予め湾曲して形成されていることを特徴とする。
【選択図】図1
Description
また、薬剤の投与に使用される注射器は、円筒状のシリンダと、可動式のピストンとを有するものが知られているが、例えば、予防接種などでは、スタンプ式で薬剤が注入される場合もある。
薬液を注入する針本体の少なくとも先端部分が、延出方向に向かって予め湾曲して形成されていることを特徴としている。
本発明に係る注射針は、薬液が注入される薬液カートリッジに接続されても良い。
このような注射針は、糖尿病患者が用いるインシュリンの注射器のように、針の先端に薬液を塗布しておき、対象物に押し付けるような注射器にも適用可能である。また、シリンダとピストンを備えた通常の注射器にも適用可能である。
図1は本発明の一実施例による注射器を示したものである。
したがって、このように注射針10が予め湾曲された注射器2を用いる場合に、図2に示したように、皮下組織に対し、湾曲した針先端部10a側を上向きにし、斜め方向から上方に向かってゆっくりと挿入すれば、その針先端部10aは、表皮12に沿って前進する。これにより、神経終末や分泌線、血管などが存在する真皮14に針先が到達することは良い。また、注入されるヒアルロン酸などは、表皮12の内部に注入され、この部分から皮膚深部に浸透される。これにより、身体内のヒアルロン酸と一緒になってみずみずしい肌を長期間に渡って、持続させることができる。また、結果として、小ジワができた部分にハリを持たせることができる。
