背景技术
很多医疗器械在深入人体内时都会不同程度地对人体造成机械性损伤，使用医用器械润滑油可能最大程度减少对身体组织、黏膜的损伤。
目前，市场上的医用润滑剂主要有水溶性润滑剂、硅树脂润滑剂、润滑油三类，其中，润滑油是较为理想的医用润滑剂，其来源广泛、成本低廉、安全无刺激。因此，在医疗临床治疗过程中，润滑油是最理想、最安全的医用润滑剂。使用润滑油能够有效防治医用器械生锈、延长医用器械的使用寿命。
但目前常用的医用器械润滑油大多为矿物油基润滑油，但矿物油存在使皮肤、黏膜不透气以及不够环保的缺点，因此，开发一种水溶性的植物油基医用器械润滑油是亟待解决的一个问题。

进一步地，所述聚乙烯吡咯烷酮为聚乙烯吡咯烷酮-K30。
进一步地，按重量份计算由如下组分组成：小麦胚芽油11.5％、羟甲基纤维素2.4％、聚乙烯吡咯烷酮-K30 3.6％、丁卡因0.5％、对羟基苯甲酸甲酯4.5％、吐温-801.2％，余量为去离子水。
或，按重量份计算由如下组分组成：小麦胚芽油14.2％、羟甲基纤维素4.2％、聚乙烯吡咯烷酮-K30 4.2％、丁卡因1.3％、对羟基苯甲酸甲酯3.2％、吐温-80 2.2％，余量为去离子水。
本发明还提供了上述医用器械润滑油的制备方法，其具体步骤如下：(1)将按配方的重量份数计算得到的所述羟甲基纤维素、聚乙烯吡咯烷酮、丁卡因、对羟基苯甲酸甲酯、吐温-80、余量的水加入混合器中在25-35℃下振荡分散，转速为800-1200rpm，分散时间为0.5-1h(2)将按配方的重量份数计算得到的小麦胚芽油缓慢加入到混合器中的上述混合物中，在40-50℃下振荡分散，转速为1500-1800rmp，分散时间为20-40min，即得到医用器械润滑油。
