PICC (Peripherally Inserted Central Catheter)

The invention relates to a PICC (Peripherally Inserted Central Catheter) which comprises an infusion tube and a flushing pipe, wherein the infusion tube is used for transmitting drug, and a notch is formed at the front end of the infusion tube so as to output the drug; the flushing pipe is used for transmitting flushing fluid; the flushing pipe surrounds the infusion tube and is arranged outside the infusion tube at a preset interval; at least one kerf is formed on the pipe wall of the flushing pipe; the kerf is opened under the action of an internal pressure, so that the flushing fluid rushes out to flush the periphery of the PICC; the front end of the flushing pipe is connected to the front end of the infusion tube. 种外周静脉置入中心静脉导管，其包括：输液管和冲洗管；所述输液管用于传输药物，所述输液管前端形成有切口，以将药物输出；所述冲洗管用于传输冲洗液；所述冲洗管围绕所述输液管以预定间隔设置在所述输液管的外侧；所述冲洗管的管壁上形成有至少个切缝，所述切缝在内部压力的作用下打开，使得所述冲洗液冲到外部而冲洗所述外周静脉置入中心静脉导管的外周；所述冲洗管的前端连接于所述输液管的前端。
