A new stepless needle-dilator is described which allows arterial puncture and dilation in a single step using a single wall puncture technique. The new needle-dilator causes significantly less arterial damage than a conventional dilator (p less than 0.05). Additionally, time and cost savings are realized by clinical users.
描述了一种新型无级针扩张器，其允许使用单壁穿刺技术在单个步骤中进行动脉穿刺和扩张。与传统扩张器相比，新型针扩张器对动脉造成的损伤明显更小（p小于0.05）。此外，临床用户实现了时间和成本的节省。
