카테터 조립체는 카테터(18)와, 카테터(18) 내에 배치된 날카로운 원위팁을 갖는 니들(12)과, 그를 통해 통과하는 니들(12)을 갖는 카테터(18)에 연결된 카테터 허브(14)로서, 카테터 허브는 카테터(18)를 통한 유체의 유동을 선택적으로 허용하거나 차단하는 밸브(38), 제1 위치와 제2 위치 사이에서 이동하는 밸브 액추에이터(54), 및 제2 위치로부터 제1 위치로 밸브 액추에이터(54)를 복귀시키는 복귀 부재(56)를 포함하는, 카테터 허브(14)와, 니들(12)의 날카로운 원위팁을 에워싸는 니들 보호 부재(176)를 포함한다. A catheter assembly (10) comprises a catheter (22), a needle (12) having a sharp distal tip disposed in the catheter (22), a catheter hub (14) housing the catheter (22) and the needle (12), the catheter hub (14) having a collar (34) including a notch (36), a needle shield (20) connected to the catheter hub (14) when the needle (12) is in a first position, and a clip (40) disposed in the needle shield (20) that cooperates with the needle (12), wherein the clip (40) engages the catheter hub (14) in the first position of the needle (12), and the clip (40) disengages the catheter hub (14) via the notch (36) when the needle (12) is retracted to a second position to enclose at least a portion of the needle (12). The clip (40) is mounted in the outer housing (38) of the needle shield (20) via a spade (66) having an outer wall (70) exposed to the outside of the needle shield (20), in order to reduce the overall width of the needle shield (20).
