카테터 조립체(2)는 카테터 허브(4); 그 근위 단부에서 카테터 허브의 원위 단부에 연결되는 중공의 관형 카테터(10); 니들 팁(36)을 가지는 니들(30); 그 근위 단부와 원위 단부 사이에서 카테터 허브에 그 원위 단부에서 연결되는 중공의 연장 튜브(62); 카테터 허브의 챔버 내에 배치되는 밸브 조립체(70)를 포함하며; 밸브 조립체는, 연장 튜브의 원위 단부를 폐쇄하고 연장 튜브 내의 압축 유체의 작용 하에서 개방할 수 있는 제1 밸브 부재(72)와; 카테터 허브의 근위 단부로 또는 근위 단부로부터 챔버를 통한 유체의 유동을 방지하는 제2 밸브 부재(74)를 포함한다. 니들 가드 조립체(102)가 또한 제공된다. A needle guard assembly (120) for a catheter assembly, the needle guard assembly comprising: a housing (122) for receiving a needle (30) extending therethrough and having a distal end and a proximal end and a lengthwise axis between the distal and proximal ends, the housing being connectable at the distal end of the housing to a proximal end of a catheter hub (4); a needle guard (140) disposed within the housing, the needle guard comprising: a needle trap (142) moveable between a ready position, in which the needle trap is held to one side of a needle shaft of a needle extending through the housing, and a protected position, in which the needle trap blocks a sharpened needle tip (36) of a needle within the housing, said needle trap comprising a first end and a second end: a resilient arm (150) biasing the needle trap into the protected position, the resilient arm bearing against an inner wall of the housing to urge the needle trap into the protected position; and a coupling arm (160) for coupling the housing to a proximal end of a catheter hub in the ready position; wherein the needle trap and the resilient arm are folded together to one side of a needle shaft in the ready position; wherein the resilient arm is rotated in a first direction relative to the lengthwise axis of the housing and the needle trap is rotated in a second direction relative to the lengthwise axis of the housing when the needle trap moves from the ready position to the protected position, the second direction being opposite the first direction; and a lateral or side member (144) extends proximally from the needle trap, wherein the lateral or side member is configured to prevent the needle from moving laterally out of the needle trap; and wherein the coupling arm is attached to the second end of the needle trap along a line extending generally perpendicularly to the lengthwise axis of the housing.
