医疗管材及其制作方法
摘要：
本发明提供了一种医疗管材及其制作方法。所述医疗管材包括至少一层热塑型聚酰亚胺涂层和至少一层热固型聚酰亚胺涂层，所述热塑型聚酰亚胺涂层和所述热固型聚酰亚胺涂层由所述医疗管材的内侧至外侧依次堆叠设置。本发明的医疗管材可以在保证医疗管材具备所需的机械强度的基础上，提高医疗管材的柔韧性和延伸性，从而可以缓解过硬的医疗管材容易对神经组织造成破坏的问题，以及容易产生裂纹的现象，并且在使用本发明提供的医疗管材时，还能够提高医疗管材在传输过程中其扭转传递推送效率。
摘要（英）：

The invention provides a medical tube and a manufacturing method thereof. The medical tubing includes at least one layer of a thermoplastic polyimide coating and at least one layer of a thermoset polyimide coating. The thermoplastic polyimide coating and the thermoset polyimide coating are sequentially stacked from the inside to the outside of the medical tube. The medical tube of the invention can improve the flexibility and extensibility of the medical tube on the basis of ensuring the required mechanical strength of the medical tube, the problem that the hard medical tube is easy to cause damage to the nerve tissue, and the phenomenon that cracks are easily generated can be alleviated, and when the medical tube provided by the present invention is used, the torsional transmission pushing efficiency of the medical tube during transport is enhanced.
