Abstract
Description
この実施例では、成型カニューレ140は、端部は先細りか丸くなっている、プラスチックの硬い、略管状の部材である。成型カニューレ140の端部は、隔壁124に予め形成されたスリットを貫通するために使用され、このように延長チューブ134とカテーテル108との間の密封流体接続を提供する。流体は、成型カニューレ140を通って、隔壁124を通り、次に、くさび118を通って、カテーテル108に流れる。隔壁124は、カテーテル108を通る以外には、液体がベース102から出たり、漏出するのを防ぐ、自己シール機能を提供する。1つの実施例によると、成型カニューレ140は、流体コネクタ126の一体部品として形成されている。
そして、ユーザは、より望ましい回転又は円周位置に流体コネクタ188の位置を変更し、そして、流体コネクタラッチ204を対応するベースラッチスロット210にロックするために、起動レバー202を放す。図41は、そこで流体コネクタラッチ204と起動レバー202が回動する、リビングヒンジ209を示している。
