Title
(JA) 自動注射器
Abstract
(JA)

本発明は、液体薬剤(M)の用量を投与するための自動注射器(1)を示し、この自動注射器(1)は、中空針(19)、およびシリンジ(7)を封止し薬剤(M)を変位させるためのストッパ(10)を備えたシリンジ(7)を収容するように配置され、遠位端(D)および注射部位に当てる予定のオリフィスを備えた近位端(P)を有する細長いハウジング(2)に対して、シリンジ(7)が、摺動自在に配置される、該細長いハウジング(2)と、起動時に、針(9)を、ハウジング(2)の内部の覆い位置からオリフィスを通り近位端(P)を越えて前進位置まで押し、薬剤(M)の用量を供給するためにシリンジ(7)を操作し、注射部位からの自動注射器(1)の取り外しによって針(19)を覆うことが可能な、ばね手段(14)と、手動操作前に加圧状態でばね手段(14)をロックするように配置され、手動操作時に注射するためのばね手段(14)を解除することが可能な、起動手段(4、20、24)とを備え、ばね手段(14)が、ねじりばね(14)であり、第1のギヤ装置(13、13.1、9)および第2のギヤ装置(15、11.1、11)が、ねじりばね(14)の第1の端部(14.1)および第2の端部(14.2)からのトルクを並進運動力へとそれぞれ変換するように配置され、第1の端部(14.1)が、ハウジング(2)に基礎を置くことが可能になるように配置され、第2の端部(14.2)が、針(19)を前進させ用量を供給するために第2のギヤ装置(15、11.1、11)を介してプランジャ(11)に対して作用するように構成され、起動手段(4、20、24)が、第2のギヤ装置(15、11.1、11)を阻止または解除するように配置され、第1の端部(14.1)が、第1のギヤ装置(13、13.1、9)を介した並進運動を引き起こすことにより、針(19)が覆われるように、ハウジング(2)への基礎から解除可能であることを特徴とする。
