桡动脉置管常用于心脏术后进行有创血压的监测,不但能直观方便地观察到患者的动态血压变化,且能保持采集动脉血的通路。但置管期间管路在动脉内的固定较为困难,常因患者躁动、腕部活动等导致置管部位穿刺处渗血、管道打折,以致测量值不准确,甚至导致管路滑脱出体外,引起出血等护理意外。传统的用于静脉输液的固定板无法满足桡动脉固定的要求,不能满足手腕部的解剖特点,固定后也不能随时观察置管处的情况,并且传统的硬塑料板应用时间较长时容
Radial artery catheterization is often used in patients with invasive heart blood pressure monitoring, not only intuitive and easy to observe the patient’s dynamic blood pressure changes, and can maintain the acquisition of arterial blood access. However, during catheterization, the intra-arterial fixation of the tubing is more difficult. Patients often suffer from restlessness and wrist movements, resulting in bleeding at the puncture site of the catheter site and discarding of the tubing, resulting in inaccurate measurements and even slippage of the pipelines, causing Bleeding care accident. Traditional fixed plate for intravenous infusion can not meet the requirements of radial artery fixation, can not meet the anatomical characteristics of the wrist, can not be observed at any time after the fixed catheter at the situation, and the traditional hard plastic plate longer time tolerance
