Description

眼底动脉阻塞治疗过滤器
技术领域
本实用新型涉及一种医疗器械,具体涉及一种眼底动脉阻塞过滤装置。
背景技术
“眼底动脉硬化”是60岁以上老年人常见的一种慢性眼底血管改变,随着年龄的增长,发病率也由之增高,约为40%-80%。其主要表现为眼底动脉血管变细,透明度降低,颜色变淡,反光性强,血管平直,分支成锐角等情况。目前,没有有效的治疗方法。
发明内容
发明目的:本实用新型的目的是为了克服现有技术中的不足,提供一种患者通过血液体外循环,有效降低血液粘稠度的眼底动脉阻塞治疗过滤器。
技术方案:为了解决上述技术问题,本实用新型所述的眼底动脉阻塞治疗过滤器,它包括壳体,在所述壳体顶部分别设有血液入口和排气口,在所述壳体底部设有血液出口,在所述壳体内设有过滤层,所述过滤层从上往下包括两层孔径为0.4-0.5μm的碳膜和一层孔径为0.2μm的聚醚砜过滤膜,两层碳膜的厚度相同,每层碳膜的厚度为5mm,单层碳膜和聚醚砜过滤膜的厚度比为(9-12):1。
所述聚醚砜过滤膜的厚度为0.5 mm。
所述壳体的直径为100 mm。
所述壳体分为上盖和下盖,它们为一体式结构。
有益效果:本实用新型与现有技术相比,其显著优点是:本实用新型整体结构简单,采用一体式结构,加工方便,加工效率高,采用厚度比为(9-12):1的孔径为0.4-0.5μm的碳膜和孔径为0.2μm的聚醚砜过滤膜,并且碳膜设置两层,患者通过血液体外循环,有效降低血液粘稠度和血液中的其它有害物质,从而有效治疗眼底动脉阻塞,符合实际使用要求。
附图说明
图1是本实用新型的结构示意图。
具体实施方式
下面结合附图和实施例对本实用新型作进一步的说明。
如图1所示,本实用新型所述的眼底动脉阻塞治疗过滤器,它包括壳体1,在所述壳体1顶部分别设有血液入口2和排气口3,在所述壳体1底部设有血液出口4,在所述壳体1内设有过滤层,所述过滤层从上往下包括两层孔径为0.4-0.5μm的碳膜5和一层孔径为0.2μm的聚醚砜过滤膜6,两层碳膜5的厚度相同,每层碳膜5的厚度为5mm,单层碳膜5和聚醚砜过滤膜6的厚度比为(9-12):1;所述聚醚砜过滤膜6的厚度为0.5 mm;所述壳体1的直径为100mm;所述壳体1分为上盖7和下盖8,它们为一体式结构。本实用新型整体结构简单,采用一体式结构,加工方便,加工效率高,采用厚度比为(9-12):1的孔径为0.4-0.5μm的碳膜和孔径为0.2μm的聚醚砜过滤膜,并且碳膜设置两层,患者通过血液体外循环,有效降低血液粘稠度和血液中的其它有害物质,从而有效治疗眼底动脉阻塞,符合实际使用要求。
本实用新型提供了一种思路及方法,具体实现该技术方案的方法和途径很多,以上所述仅是本实用新型的优选实施方式,应当指出,对于本技术领域的普通技术人员来说,在不脱离本实用新型原理的前提下,还可以做出若干改进和润饰,这些改进和润饰也应视为本实用新型的保护范围,本实施例中未明确的各组成部分均可用现有技术加以实现。
