Abstract
Description
Claims (1)
- 【特許請求の範囲】 1.人工心肺装置用血液リザーバにおいて、 a)通気可能な剛性ハウジングと、 b)血液を内部に導入するために前記ハウジングに設けられた血液入口と、 c)前記ハウジングの下側に前記ハウジングと流体連通した状態で密封をなして 連結され、前記袋内に液体がない場合に密封をなして潰れるように構成された、 可撓性の袋と、 d)前記袋の前記ハウジングとは反対側の端部に設けられた、血液を前記ハウジ ング及び前記袋から排出するための血液出口と、 を有することを特徴とする、人工心肺装置用血液リザーバ。 2.前記ハウジングの前記下側には、実質的に矩形の細長い狭幅の界面を前記ハ ウジングと前記袋との間に形成するように前記袋に向かってテーパが形成され、 前記袋は互いに近接した一対の平行な可撓性フィルムで形成されている、請求項 1に記載の血液リザーバ。 3.前記テーパには、血液に付く傷を最少にするため、前記ハウジングから前記 袋内への実質的に均等な血流を維持するように湾曲が付けてある、請求項2に記 載の血液リザーバ。 4.前記ハウジングには、前記ハウジング内の血液の所与のレベルについて前記 リザーバ内の血液の容積を表示するため、容積目盛りが設けられている、請求項 1に記載の血液リザーバ。 5.前記袋の容量は、前記リザーバの総容量のほぼ10%又はそれ以下である、 請求項1に記載の血液リザーバ。 6.前記袋の容量の前記ハウジングの容量に対する比は十分に小さく、そのため 、前記リザーバの容量の正確さは、臨床的設定で体外血液容積を決定する上で適 当である、請求項1に記載の血液リザーバ。
