Description

驻极体医用敷料
技术领域
本发明公开一种具有抗菌抑菌的医用敷料，具体说是一种氟塑料驻极体材料的医用敷料，属于医疗用品领域。
背景技术
目前医疗创伤一般使用灭菌的纱布敷料，敷在创面上再用绷带包扎，但灭菌的纱布敷料主要起到对创伤的保护和护理，本身并不具有消炎灭菌的功效，只是依靠药物对创伤护理和防感染。
发明内容
本发明公开一种具有抗菌抑菌、消炎止痛功能效，防尘防水、透气性好的氟塑料驻极体医用敷料。
本发明解决其技术问题所采取的技术方案是，将氟塑料加工细化制成吸附剂载体，所述的吸附剂载体为海绵膨体材料，采用驻极电晕法或击穿法等驻极技术处理，加工制成驻极体医用敷料。
所述的驻极体是对一些特殊性能的材料，在强外电场等因素的作用下极化并能长期存储电荷的电介质材料。在驻极体材料中存在静电场电荷，材料的孔隙类似无数个无源集尘电极，当空气中的带电微粒尤其是亚微米粒子通过这些孔隙时，在电场力的作用下被阻挡或捕获，气流中的中性微粒子因感应或极化而成为偶极子也被有效的捕获，因此，驻极体材料对粉尘有突出的阻挡能力，可阻挡粉尘携带的细菌感染创面。
细菌和病毒具有天然驻极态(带负电)通常依附在空气中的粉尘上，随气流散布传播，当它们通过驻极体材料的孔隙时，由于驻极体产生的强静电场和微电流会刺激细菌使蛋白质变异，损伤细菌的细胞质及细胞膜，破坏细菌的表面结构导致细菌死亡。驻极体形成的电场对各类细菌的繁殖具有明显的抑制功效。
所述的氟塑料驻极体为聚四氟乙烯(PTFE)、全氟代乙丙烯(FEP)、乙烯-四氟乙烯共聚物(ETFE)等材料或聚四氟乙烯(PTFE)和全氟代乙丙烯(FEP)的复合材料，加工细化制成吸附剂载体，将吸附剂载体进行驻极技术处理，使其成为驻极体。所述的吸附剂载体为上述氟塑料制成的海绵膨体材料。
所述的氟塑料驻极体海绵膨体材料，具有优良的透气、防水性能，当海绵膨体材料的孔径选择在0.1-0.5μm时，该直径是水滴直径的1/2000-1/5000，是水蒸气分子的700倍，因此，外面的水分不能渗入，而身体的汗蒸气可畅通透出，不聚积在皮肤与海绵膨体材料之间。
本发明的有益效果是，驻极体医用敷料具有透气性好、防湿、消炎、抗菌抑菌的特性，其性能和治疗护理效果远优于现用药浸纱布敷料，而且不会因纱布与创伤结痂，给患者造成痛苦给治疗带来不便。本发明还具有抗菌抑菌的功效，不使用药物也可达到消炎止痛，防感染的效果。本发明还具有优异的防水性，即使在潮湿的环境中水分也不会渗入侵害创伤面或伤口，而且驻极体医用敷料具有耐酸、耐碱、耐高温、不受腐蚀、不溶于水和酒精等溶液，性能稳定，无毒无害、安全可靠，是一种具有物理治疗功能的新型治疗用品，特别适用战场急救、野外急救、抢险救灾情况下使用。
附图说明
以下结合附图和实施例对本发明进一步说明。
图1为本发明驻极体医用敷料示意图。
具体实施方式
如图1所示，将氟塑料加工细化制成海绵膨体材料，采用驻极体电晕法或击穿法等驻极技术处理，使其成为驻极体，将驻极体海绵膨体材料加工成不同规格不同形状的医用敷料。
本发明中所述的氟塑料驻极体医用敷料，解决了现用的医用敷料存在的不足，利用其抗菌抑菌和防尘防水、透气性好的性能，实现了不使用药物防止创伤感染进行创伤治疗和护理效果，与药物配合可取得更好的疗效。驻极体医用敷料还具有耐酸、耐碱、耐高温、不受腐蚀、不溶于水和酒精等溶液，性能稳定，无毒无害、安全可靠，是一种具有物理治疗功能的新型治疗用品，特别适用战场急救、野外急救、抢险救灾情况下使用。
本发明公开的实施例，为较佳实施例，并不限制本发明的实施范围，凡在本发明揭露的原理内的变化、变形、替换、均属于本发明专利申请保护范围。
