硬膜外麻醉导管尖端柔软性影响因素研究

Study on Influencing Factors of the Tip Softness of Epidural Anesthesia Catheter

摘要: 该文旨在研究硬膜外麻醉导管尖端柔软性影响因素。从原材料、尖端结构、尖端处理工艺、导管成型外径四方面用柔软度测试仪测试硬膜外麻醉导管尖端柔软性。研究发现，高柔软性延展性的高分子材料、尖端为圆滑结构，尖端软化处理工艺，合适的外径可有效改进硬膜外麻醉导管尖端柔软性。

Abstract: This article aims to study the factors affecting the flexibility of the tip of an epidural anesthesia catheter. The flexibility of the tip of the epidural anesthesia catheter was tested with a softness tester from four aspects:raw materials, tip structure, tip processing technology, and the outer diameter of the catheter. Highly flexible and malleable polymer material with a smooth tip, the tip softening process and the proper outer diameter can effectively improve the tip flexibility of the epidural anesthesia catheter.
