Description
(項目1)注射器の先端部に取り付けられる薬液注入針であって、
該薬液注入針は、薬液注入針の本体と、該薬液注入針本体の先端表面より突出する複数本の針とを有し、該針の先端が針の長手方向に対して斜めに切断されて針の先端に薬液の吐出口が形成され、
該複数本の針は、薬液注入針本体の先端表面の仮想の真円の円周上に等間隔で配置され、
該各針の吐出口の向きが、実質的に上記真円の中心に向かう半径方向、もしくは実質的に上記真円の中心方向とは反対方向を向いている薬液注入針。
(項目2)前記各針の、薬液注入針の先端表面の前記真円の中心からの距離が1〜2.5mmである、項目1に記載の薬液注入針。
(項目3)前記薬液注入針の先端表面より突出する針の寸法が0.1〜3mmである、項目1または2に記載の薬液注入針。
(項目4)前記針の本数が2〜10本である、項目1〜3のいずれかに記載の薬液注入針。
(項目5)前記針の本数が3本であり、該各針の吐出口の向きが、実質的に該薬液注入針本体の先端表面の前記真円の中心方向とは反対の方向を向いている、項目1〜3のいずれかに記載の薬液注入針。
(項目6)前記隣接する針間のピッチが1〜10mmである、項目1〜5のいずれかに記載の薬液注入針。
(項目7)薬液が充填される注射器と、該注射器の先端部に取り付けられる薬液注入針と、を有する経皮投薬装置であって、
該薬液注入針は、薬液注入針の本体と、該薬液注入針本体の先端表面より突出する複数本の針とを有し、該針の先端が針の長手方向に対して斜めに切断されて針の先端に薬液の吐出口が形成され、
該複数本の針は、薬液注入針本体の先端表面の仮想の真円の円周上に等間隔で配置され、
