Abstract
Description
[0002]本開示は、任意のタイプの自動注射器および実施形態によっては針支援式注射器を含む注射装置のための緩衝器に関し、その注射装置または針支援式ジェット注射器は、テストステロンまたはミダゾラムなどの薬剤用、または高粘度の製剤や急速投与を必要とする薬などの特別な用途の注射装置または針支援式ジェット注射器であり得る。
[0011]一実施形態では、スリーブは、荷重が取り除かれたときに実質的にその元の長さに戻る。
[0013]一実施形態では、圧縮性要素は、スリーブの遠位端に配置される。別の実施形態では、圧縮性要素は、スリーブの近位端に配置される。他の実施形態では、圧縮性要素は、スリーブの中間部分に配置される。
[0015]本発明の一実施形態において、本発明は、緩衝部材を有する自動注射器を提供するステップを含む、自動注射器の故障率を低減するための方法に関する。
[0073]一実施形態では、図1に示されるように、エネルギー源120(たとえば、ばね)がガード106から分離される。一実施形態では、近位端エネルギー源120がハウジング102に結合される。エネルギー源120がガード106から分離されることにより、浮動トリガ部材300の回転の見かけの摩擦が著しく低減される。次いで、これが、図9Aおよび図9Bを参照して後で説明されるように、伸張位置から発射位置へガード106を移動するために必要な力の量を実質的に低減させる。詳細には、エネルギー源120によって引き起こされる部品の圧縮が実質的に取り除かれ、それにより、注射装置100の使用中のガード106の移動に対する見かけの摩擦および抵抗の量を著しく低減させる。
