Description
Claims (4)
- 輸液アセンブリ用のエラストマー性ポンプであって、
マンドレルと、
前記マンドレル上に配置された膨張可能なエラストマー性ブラダと、を備え、
前記マンドレルは、
第1の端部からその反対側の第2の端部まで所定の長さにわたって延在し、外径を有する本体部と、
前記本体部内に延在するボアと、
前記第2の端部の近傍に形成され、前記ボアと流体連通する入口ポートと、
前記第1の端部の近傍に形成され、前記ボアと流体連通する充填ポートとを有し、
前記長さの中間点における前記外径は、前記第1の端部及び前記第2の端部の各々における前記外径と異なり、
前記外径は、前記第1の端部、前記第2の端部、前記長さの中間点のいずれか部分において他の2つの部分より小さくなり、
前記充填ポートは、前記外径の最も小さい部分の周囲面上に形成され、
前記ブラダは、管形状で、第1のブラダ端部及び第2のブラダ端部に開口を有し、使用時には前記マンドレルが貫通するように前記マンドレル上に配置され、前記第1のブラダ端部及び前記第2のブラダ端部が、それぞれ前記マンドレルの前記第1の端部及び第2の端部の近傍で前記マンドレル上に密封的に固定され、
非膨張時において、前記ブラダは、ブラダ外径と、ブラダ内径と、前記ブラダ外径と前記ブラダ内径との差である壁厚とを有し、
前記壁厚は、前記第1のブラダ端部における第1の壁厚から前記第2のブラダ端部における、前記第1の壁厚より小さい第2の壁厚まで徐々に増加し、
前記ブラダ内径は、前記第1ブラダの端部における第1のブラダ内径から前記第2のブラダ端部における第2のブラダ内径まで徐々に小さくなることを特徴とするポンプ。 - 請求項1に記載のエラストマー性ポンプであって、
前記マンドレルの前記長さの中間点における前記外径は、前記第1の端部における前記外径よりも大きく、かつ、前記第2の端部における前記外径よりも小さく、その結果、前記マンドレルは、前記第2の端部から前記第1の端部に向かって概して先細になることを特徴とするポンプ。 - 請求項1または2に記載のエラストマー性ポンプであって、
前記マンドレルは、前記第1の端部及び前記第2の端部の各々に溝を有することを特徴とするポンプ。 - 請求項3に記載のエラストマー性ポンプであって、
第1のOリングによって、前記ブラダは前記マンドレルの前記第1の端部に固定され、
第2のOリングによって、前記ブラダは前記マンドレルの前記第2の端部に固定され、
前記各Oリングは、前記マンドレルの前記第1の端部及び前記第2の端部の各々の前記溝に嵌合され、その結果、前記ブラダは、前記Oリングと前記溝との間に固定されることを特徴とするポンプ。
