Description

限位式体腔热灌注过滤器 技术领域
本实用新型涉及过滤装置， 具体地说, 涉及针对各类肿瘤等引起 的胸、腹水及肿瘤手术切除后， 将进行体腔热灌注治疗的化疗药物过 滤的一种限位式体腔热灌注过滤器。. 背景技术
体腔热灌注技术在肿瘤治疗中运用得非常广泛,该技术是将化疗 药物稀释液或癌性积液吸引到治疗机的无菌容器内加热后，通过植入 体腔的两根导管注入体腔,使化疗药物稀释液或癌性积液在人体体腔 与无菌容器间形成循环， 通过计算机全程动态监测和反馈调节， 使治 疗液或癌性积液保持恒定的温度， 稳定流量、 流速， 循环灌注， 扩大 药物在体腔内的作用面积, 促进药物的吸收，减少营养物质丟失， 并 以其显著的疗效正被人们逐渐接受， 临床应用也日益广泛。 然而， 在 具体使用时，过滤器是先将药液进行过滤后再流进热交换器中进行加 热，而过滤器的过滤效果也将直接影响到体腔热灌注治疗仪的可靠性 以及药液的治疗效果 , 而现有体腔热灌注台疗仪的过滤器的结构、构 造以及性能并非绝对完美， 因此， 还有待进一步的完善。
发明内容 本实用新型所要解决的技术问题在于提供一种限位式体腔热灌 注过滤器， 通过对化疗药物稀释液的过滤作用， 以提高药液的纯度， 从而提高药液的治疗效果。 .
本实用新型的技术问题是按如下技术方案实现的：构造一种限位 式体腔热灌注过滤器， 其特征在于，包括呈限位匹配的两个盖子及其 空间内呈固定设置的若干层过滤网， 其中， 在第一盖子的边沿 A设置 有限位槽，在第二盖子的边沿处对应设置有与所述限位槽呈限位配合 的凸边。 在具体实施时， 所述过滤网优选采用四层结构， 并优选设置 于所述第二盖子内，并且,所述限位槽的凸棱顶住所述过滤网的边缘， 在具体使用时， 具有固定过滤网的作用， 增强使用的可靠性。
实现本实用新型的限位式体腔热灌注过滤器， 具有如下优点： 实 现了对化疗药物稀释液的过滤功能， 有效提高了药液的纯度，增强了 化疗药物对肿瘤细胞的杀復作用以及治疗效果， 本实用新型构造新 颖， 结构简单， 可靠性好， 实施容易。 附图说明
图 1为本实用新型限位式体腔热灌注过滤器的结构剖示图； 图 2为本实用新型配套的体腔热灌注治疗仪实施例结构示意图。 具体实施方式
如图 1所示的一种限位式体腔热灌注过滤器,包括呈限位匹配的 第一盖子 11及第二盖子 12， 并在两个盖子所形成的空间内固定设置 有过滤网 2， 并优选 ©层结构叠加, 并且 在^一盖子 11 的边沿处 设置有限位槽 10， 在第二盖子 12 的边沿处对应设置有与限位槽 10 呈限位配合的凸边 13。 为了增强在使用时的可靠性， 优选将过滤网 2 设置于第二盖子 12内, 通过限位槽 10的凸棱 16顶住过滤网 2的边 . 缘， 实现对过滤网的固定作用。 .
