Description

一种双层抗菌导尿管
技术领域
本发明涉及一种双层抗菌导尿管。
背景技术
现有的导尿管一般为PVC、硅胶、橡胶材质，为了在插入和拔出尿道时不伤害患者，通常在表面涂覆亲水涂层，增加润滑性能，还有在表面涂覆一层抗菌涂层防止感染，但实际应用中，涂覆的方法可靠性差，亲水涂层、抗菌涂层易脱落，亲水涂层在插入导尿管时有效，留置数天后抽出时涂层已没有。
发明内容
本发明的目的是克服现有技术的缺陷，提供一种双层抗菌导尿管，通过双层挤出技术，将亲水超滑涂层和抗菌涂层共挤在导尿管本体的外表面，可防止亲水超滑涂层和抗菌涂层的脱落，保持超滑功能、抗菌功能的长时间有效性。
实现上述目的的技术方案是：一种双层抗菌导尿管，包括导尿管本体和设置在所述导尿管本体外表面的功能层，所述功能层包括亲水超滑涂层和抗菌涂层，所述亲水超滑涂层和抗菌涂层通过双层挤出技术共挤在所述导尿管本体的外表面。
本发明的双层抗菌导尿管，通过双层挤出技术，将亲水超滑涂层和抗菌涂层共挤在导尿管本体的外表面，可防止亲水超滑涂层和抗菌涂层的脱落，保持超滑功能、抗菌功能的长时间有效性。
附图说明
图1为本发明的双层抗菌导尿管的结构示意图。
具体实施方式
为了使本技术领域的技术人员能更好地理解本发明的技术方案，下面结合附图对其具体实施方式进行详细地说明：
请参阅图1，本发明的最佳实施例，一种双层抗菌导尿管，包括导尿管本体1和设置在导尿管本体1外表面的功能层2，功能层2包括亲水超滑涂层和抗菌涂层，亲水超滑涂层和抗菌涂层通过双层挤出技术共挤在导尿管本体1的外表面，。
本发明的双层抗菌导尿管，通过双层挤出技术，将亲水超滑涂层和抗菌涂层共挤在导尿管本体的外表面，可防止亲水超滑涂层和抗菌涂层的脱落，保持超滑功能、抗菌功能的长时间有效性。
本技术领域中的普通技术人员应当认识到，以上的实施例仅是用来说明本发明，而并非用作为对本发明的限定，只要在本发明的实质精神范围内，对以上所述实施例的变化、变型都将落在本发明的权利要求书范围内。
