摘　　要：留置针是临床治疗中常用的医疗器械,可减少护理人员的工作量,减轻反复静脉穿刺给患者带来的痛苦。近年来,留置针的自动化生产逐渐得到普及,越来越多的医疗器械生产企业引进了留置针生产线,用于满足市场对留置针的需求。但是,受留置针自身结构设计的影响,其软管熔头部分在自动化生产时仍面临较大的挑战。在此背景下,该研究提出了一种基于可编程逻辑控制器(PLC)的留置针软管自动熔头设计方法,实现了留置针上料、熔头、检测及下料的自动化协同作业,提高了留置针生产的自动化程度及生产效率;此外,系统配有触摸屏,可实时显示熔头系统的运行状态,同时可通过触摸屏单独控制各个工位,便于在生产车间的操作使用。The indwelling needle is a commonly used medical device in clinical treatment. The use of the indwelling needle can reduce the workload of nurses and alleviate the pain of patients caused by repeated venipuncture.At present, the automated production of indwelling needles has become more and more popular, and more and more medical device manufacturers have introduced indwelling needle production lines to meet the market demand for indwelling needles. However, due to the structural design of the indwelling needle itself, the hose melting head part of the indwelling needle still faces great challenges in automated production. Based on this, this study proposed a programmable logic controller(PLC)-based automatic melting head design method for the indwelling needle hose, which can realize the automatic collaborative operation of indwelling needle feeding, melting head, detection and unloading,improve the automation degree of indwelling needle production, and greatly improve production efficiency. Besides this equipment is equipped with a touch screen, which can display the operating status of the melting head system in real time. At the same time, each station of the equipment can be individually controlled through the touch screen, which is convenient for operation and use in the production workshop.
