Description
自動注射装置は2つの主要な素子、すなわち、充填された注射器50を収容する図面の左手に示すリザーバ部分と、注射器の自動的な挿入及び吐き出しを行う部品をその中に収容する図面の右手に示すパワーパックとを有する。2つの主要な素子はハウジング16とパワースリーブ1との間の銃剣式の接続を介して互いに着脱自在に接続される。次の説明において、注射針37が位置する自動注射装置の側を前部と呼ぶ。
Claims (6)
- 注射針(37)と、ハウジング(16)と、活性物質のための容器(50)と、上記活性物質を押し出すために上記容器(50)内で変位できる注射器ピストン(52)と、上記ハウジングに対して変位できる針保護装置(17)とを有する、活性物質を注射するための注射装置において、
上記注射針(37)が皮膚へ進入する間、上記針保護装置(17)が上記ハウジング(16)に対して実質上一定の位置を維持し、バネ素子(18)が圧迫され、同バネ素子が、皮膚からの当該注射針(37)の取り外し後に、該針を取り囲む位置へ当該針保護装置(17)を前方に押圧すること、上記容器(50)が、上記注射針の皮膚への進入中に上記ハウジング(16)内で引き戻し位置から前進位置へ変位される摺動スリーブ(21)内に収容され、上記針保護装置(17)が係止手段(35、38)によりその前進位置において自動的に係止され、上記係止手段(35、38)は、当該針保護装置(17)及び上記摺動スリーブ(21)がその前進位置に位置するときに、当該係止手段が該針保護装置(17)と当該摺動スリーブ(17)との間で作動すること、および、上記係止手段が、上記摺動スリーブ(21)上に配置されかつ実質的に軸方向に指向した少なくとも1つの可撓性の舌片(38)を有し、同舌片が、その自由な状態において、上記針保護装置(17)の区域(35)に対する軸方向のストッパを形成することを特徴とする注射装置。 - 上記係止手段(35、38)を解除する手段(39)が設けられ、係止を解除する該手段は、該摺動スリーブ(21)がその引き戻し位置にあるときに、作動することを特徴とする請求項1に記載の注射装置。
- 係止を解除する上記手段が、上記ハウジング内に配置されかつ内方へ突出する突起(39)を有し、同突起が、当該摺動スリーブ(21)の引き戻し位置において、上記可撓性の舌片(38)を含む該摺動スリーブ(21)の部分が当該針保護装置の上記区域(35)内へ移動できるように、当該可撓性の舌片(38)を半径方向内方へ押圧することを特徴とする請求項2に記載の注射装置。
- バネ素子(18)が設けられ、同バネ素子が上記針保護装置(17)をその前進位置へ押圧し、また、上記バネ素子は、上記摺動スリーブ(21)がその前進位置へ移動するときに、同摺動スリーブにより圧迫されることを特徴とする請求項2又は3に記載の注射装置。
- キャリヤ手段(58)が設けられ、同キャリヤ手段は、上記摺動スリーブ(21)がその前進位置からその引き戻し位置へ移動するときに、同摺動スリーブにより上記針保護装置(17)を運ばせることを特徴とする請求項2ないし4のいずれかに記載の注射装置。
- 回復バネ素子(20)が設けられ、同回復バネ素子がその引き戻し位置の方向において上記摺動スリーブ(21)上に作用することを特徴とする請求項2ないし5のいずれかに記載の注射装置。
