    • An intravenous catheter device is provided which includes a catheter adapter having a fluid chamber, a needle adapter being slidably positioned within the fluid chamber, the needle adapter supporting a base of an introducer needle and a terminal end of a section of intravenous tubing such that a fluid pathway of the introducer needle is in fluid communication with a fluid pathway of the section of intravenous tubing. Following catheterization, the needle adapter is slid to a preferred proximal position whereby a sharpened tip of the introducer needle is shielded within a catheter of the intravenous catheter device, or a portion of the fluid chamber of the catheter adapter. When in the preferred proximal position, fluid communication between the catheter and a section of intravenous tubing is facilitated via the hollow body of the introducer needle.
    • 提供了一种静脉内导管装置,其包括具有流体室的导管适配器,针头适配器可滑动地定位在流体腔内,针适配器支撑导引针的底座和一段静脉内管的末端, 导引针的流体通道与静脉内管的一部分的流体通路流体连通。 在导管插入术后,针头适配器滑动到优选的近端位置,由此导引针的尖锐的尖端被屏蔽在静脉内导管装置的导管内或导管适配器的流体室的一部分内。 当处于优选的近端位置时,导管和一段静脉内管之间的流体连通通过导引针的中空体而得到促进。
