Description

一种医用抗菌绷带的制备方法
技术领域
本发明专利涉及一种绷带，具体涉及一种医用抗菌绷带的制备方法。
背景技术
严重创伤是导致劳动力丧失的主要因素之一。因此，必须使用专门的创伤绷带材料来处理创口。尽管此类绷带需求很迫切，但其现状依然非常落后，究其原因，是创口愈合过程本身的复杂性。医用绷带的理想特性包括优良的组织相容性、使用方便、减少感染的风险、加速组织愈合。它能够为创口创建一个干净、湿润的环境，并提供物理支持、创面保护，同时预防细菌感染、促进创口愈合。
医用绷带首要解决的问题是高感染风险。绷带为创口提供的湿润环境同样也适合病菌的生长和繁殖。通常，人们会让棚带包裹银离子用于杀死细菌，但是，银粒子的使用量过大会限制或降低疗效并对细胞产生不利影响。因此，可以选择在医用绷带材料上添加抗菌剂，以可控的方式释放达到杀菌的目的，同时细胞相容性更好。
发明内容
发明的目的：本发明的目的在于提供一种医用抗菌绷带的制备方法，制备的绷带不仅具有传统杀菌抑菌、洁净功能外，还具有改善血液循环，促进新陈代谢，消除疲劳，醒神健脑的效果，且制得的绷带手感滑爽，柔顺舒爽，吸湿透气，更具舒适感。
本发明采用的技术方案：一种医用抗菌绷带的制备方法，具体包括如下步骤：
a、纺纱，将医用脱脂棉纤维与海藻酸铜纤维混合，进行开松、混合、并条后进行纺纱；
b、坯巾织造，将步骤a得到的原料纱进行织造得到绷带坯巾；
c、抗菌药液制备：将穿心莲与鱼腥草和四倍于中药材重量的水一同煎煮2.5小时，再将煎煮后的药液过滤得到无渣药液，将药液置于低温减压环境下浓缩至原体积的1/4~1/5；
d、抗菌浸泡液制备：从黄连中醇提法提取黄连素，烘干，制备成粉体粒子小于5μm的超细微粉，将甲壳素、海藻酸钠分别制备成粉体粒子小于5μm的超细微粉；将两种超细微粉，步骤c的抗菌药液以及超纯水按照1:1:3:10的比例均匀混合得到抗菌浸泡液；
e、改性处理，将步骤b织好的坯巾浸入水洗机中，浴比为1:20-27，用95-100℃的水清洗25-36 分钟，待温度降低至5-10℃，再次水清洗4-8 分钟，然后在水中加入抗菌浸泡液，调整水溶液温度为65-75℃，采用水洗机浸泡40-50 分钟；
f、柔顺，将步骤e坯巾用温度为90-100℃清水煮30-40 分钟，再加入亲水柔软剂、纤维酶、聚丙烯酰胺和硫酸镁，在上述温度下继续煮10-20 分钟；
g、干燥，将绷带取出采用冷冻干燥技术使绷带表面形成凝胶层即可。
作为优选，在所述步骤c中，穿心莲与鱼腥草的比例为1:1~1:3。
有益效果：本发明所揭示的一种医用抗菌绷带的制备方法，通过煮沸方式提取出中药中的天然抗菌物质，并过滤、浓缩后得到抗菌药液，再通过黄连素和海藻酸钠间相互作用形成三维网状交联结构，将抗菌提取液容纳其中，一方面提高纱布抗菌能力，减少、降低创面感染几率，另一方面可以实现抗菌药剂的缓效释放，防止药物突释，延长抗菌时效、减少纱布更换次数并减少更换纱布给患者带来的痛苦。
冷冻干燥技术保持了绷带表面凝胶层的多孔状结构，具有高吸水性，能够快速吸收伤口渗出液保持伤口的相对干燥，创造有利于伤口愈合的局部环境。
改性处理后的绷带进行柔顺处理，制得的绷带手感滑爽，柔顺舒爽，吸湿透气，更具舒适感。
具体实施方式
下面结合具体实施例对本发明具体实施例进行详细阐述：
