To provide a catheter assembly in which a valve actuator includes a plurality of windows specifically sized and disposed to enhance saline flushing capability.SOLUTION: A catheter assembly comprises: a catheter; a needle having a sharp distal tip disposed within the catheter; and a catheter hub connected to the catheter having the needle passing therethrough. The catheter hub includes; an inner diameter; a valve that selectively permits or blocks a flow of fluid through the catheter; a valve actuator that moves between a first position and a second position; and a spring that returns the valve actuator from the second position to the first position, where a clearance fit is provided between the spring and the inner diameter.SELECTED DRAWING: Figure 1A 【課題】生理食塩水フラッシング能力を向上するように特にサイズ設定および配置された複数の窓を弁アクチュエータが含む、カテーテルアセンブリを提供する。【解決手段】カテーテルと、カテーテル内に配置された鋭い遠位先端を有する針と、針がその中を通過するカテーテルに連結されたカテーテルハブであって、内径、カテーテルを通る流体の流れを選択的に可能にするまたはブロックする弁、第１のポジションと第２のポジションとの間を動く弁アクチュエータ、および弁アクチュエータを第２のポジションから第１のポジションへ戻すばねを含むカテーテルハブとを備え、隙間嵌めが、ばねと内径との間に提供される、カテーテルアセンブリ。【選択図】図１Ａ
