Description
ユーザが注射を行う前に、保護キャップを取り外すことができるように、取外し可能な保護キャップを遠位にサポートするハウジングであって、近位にピストン駆動システムを含む、またはサポートするハウジング。取外し可能なキャップは、ハウジングに取り付けられたとき、ハウジングに対してさらに回転可能である。
ハウジングに恒久的に組み込まれて、充填済みの注射デバイスを形成する交換不能なカートリッジ。カートリッジの内部は、保存剤が処理されている液剤を含む。カートリッジは、近位面がピストンロッド駆動システムに当接している可動プランジャを有し、そのシステムは、プランジャを前方に、すなわち、カートリッジの内側で遠位方向に移動させるためのピストンロッドをさらに有する。
ユーザの皮膚を貫通するための遠位先端を有する遠位部分、反対側の近位部分、およびそれらの間のルーメンを有する針カニューレ、または中空の針の管。
針カニューレの少なくとも遠位先端を覆う展開位置から、注射を実施するために、針カニューレの少なくとも遠位先端が露出される収縮位置へと移動可能な伸縮自在に移動可能なシールド。伸縮自在に移動可能なシールドは、次の注射までの間に、針カニューレの少なくとも遠位先端を洗浄するための洗浄溶媒を含むように構成された洗浄チャンバをさらに担持する。
「注射ペン」とは、通常、書くためのペンに多少似た横長もしくは細長い形状を有する注射装置のことである。このようなペンは、通常、管状の横断面を有しているが、それらは、三角形、長方形、または正方形、あるいはこれらの幾何形状に近い任意の変形形態など、様々な横断面を容易に有することもできる。
特定の一例では、カートリッジ160の内部に含まれ、かつ伸縮式シールド110の洗浄チャンバ120に含まれる液体の医薬品保存剤を含有する薬剤は、デンマークの会社Novo Nordisk A/Sにより製作され、かつ販売されているNovoLog(登録商標)とすることができる。
・インスリンアスパルト 100ユニット/mL
・グリセリン 16mg/mL
・フェノール 1.50mg/mL
・メタクレゾール 1.72mg/mL
・亜鉛 19.6mcg/mL
