Description
技术领域
本发明涉及一种伤口敷料，具体涉及一种络合碘石墨烯无纺布敷料。
背景技术
皮肤伤口容易产生渗出液、脓液、毒素及毒性产物等，其中渗出液中含有大量的炎症因子、蛋白酶和自由基等，这些有害物质若长期停留在皮肤表面会减缓伤口的愈合。同时，为了避免外界有害微生物感染伤口，加速伤口的愈合，通常需要在伤口处敷伤口敷料。而伤口敷料一般由纱布或棉布等原料组成，而这些原料本身无抑菌功能，染有血迹的伤口敷料容易繁殖细菌，造成伤口感染，难以愈合，伤口分泌物在伤口敷料上吸附、干燥最终与伤口干枯形成结痂，为后续处理带来困难，也为患者带来痛苦。
发明内容
针对上述问题，本发明特提供了一种络合碘石墨烯无纺布敷料。
本发明的技术方案如下：
一种络合碘石墨烯无纺布敷料，包括有上层石墨烯无纺布、下层石墨烯无纺布以及夹于上、下两层石墨烯无纺布中间的含络合碘石墨烯敷芯。
作为更优方案，含络合碘石墨烯敷芯的面积为上、下层石墨烯无纺布的1/3-3/4，且位于上、下层石墨烯无纺布的正中间。该络合碘石墨烯无纺布敷料的上、下层石墨烯无纺布通过热粘接法结合。
本发明的络合碘石墨烯无纺布敷料，其石墨烯无纺布的吸水性好，能有效吸收伤口渗液，石墨烯无纺布本身不杀菌，但抑菌性强，并且其生物相容性好、无细胞毒性、无刺激，其还具有良好的载药性，含络合碘石墨烯敷芯有效碘含量9-12%，使用时无黄染、无刺激，有效杀菌效果在99.9%以上，络合碘稳定性好，在有效期内（2年）下降率仅为0.2%。
附图说明
附图1为实施例1的结构示意图。
附图2为实施例2中含络合碘石墨烯敷芯的侧视图。
附图3为实施例2中含络合碘石墨烯敷芯的俯视图。
图中，1上层石墨烯无纺布，2下层石墨烯无纺布，3含络合碘石墨烯敷芯。
具体实施方式
下面结合具体实施例对本发明作进一步详细地说明。
实施例1
该实施例如附图1中所示，包括有上层石墨烯无纺布1、下层石墨烯无纺布2以及夹于上、下两层石墨烯无纺布中间的含络合碘石墨烯敷芯3。该含络合碘石墨烯敷芯的面积为上、下层石墨烯无纺布的3/4，且位于上、下层石墨烯无纺布的正中间，上、下层石墨烯无纺布进行外沿粘合。
实施例2
该实施例包括有上层石墨烯无纺布、下层石墨烯无纺布以及夹于上、下两层石墨烯无纺布中间的含络合碘石墨烯敷芯。该含络合碘石墨烯敷芯的面积为上、下层石墨烯无纺布的1/2，且位于上、下层石墨烯无纺布的正中间，上、下层石墨烯无纺布是通过热粘接法进行外沿粘合。该实施例中的含络合碘石墨烯敷芯是如附图2、3中所示的均布鼓包的结构（鼓包面朝上），以更好地锁住络合碘。
实施例3
该实施例如附图1中所示，包括有上层石墨烯无纺布1、下层石墨烯无纺布2以及夹于上、下两层石墨烯无纺布中间的含络合碘石墨烯敷芯3。该含络合碘石墨烯敷芯的面积为上、下层石墨烯无纺布的1/3，且位于上、下层石墨烯无纺布的正中间，上、下层石墨烯无纺布是通过热粘接法进行外沿粘合。
最后说明的是，以上实施例仅用以说明本发明的技术方案而非限制，尽管参照较佳实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的宗旨和范围，其均应涵盖在本发明的权利要求范围当中。
