Description
相关申请的交叉参考
本申请是2016年4月11日提交的美国专利申请序列号15/095,435的部分继续申请,该申请在本文中通过参考全文引入。
技术领域
本发明涉及过滤器和尤其涉及厚壁切向流过滤器。
背景技术
常见的薄壁切向流过滤器膜的已知表皮或表面无法捕获通过过滤器流体中的一些元素。需要能捕获渗透流中特定元素的切向流过滤器。
发明内容
通过提供厚壁中空纤维切向流过滤器(TWHFTFF)以供灌注并收获一种或多种哺乳动物细胞培养物,本发明解决了上述和其他需求。TWHFTFF包括从入口到达出口的至少一根厚壁中空纤维。该厚壁中空纤维包括在厚壁中空纤维的内表面和外表面之间具有曲折路径的厚壁。该曲折路径包括捕获小粒子的沉降区和捕获较大粒子的缩窄区。该壁可以由HDPE或塑性材料,其中包括PES、PVDF制成且可用PVDF包覆。
根据本发明的一个方面,提供含厚壁中空纤维的切向流过滤器。该厚壁中空纤维包括曲折路径,该曲折路径选择性捕获从经过过滤器的保留流体和从过滤器的渗透物中汽提的粒子。
附图说明
根据结合附图列出的本发明的下述特定说明,本发明的上述和其他方面,特征与优点将变得更加显而易见,其中:
图1示出了根据本发明的中空纤维切向流过滤器的截面视图。
图2示出了根据本发明的厚壁中空纤维切向流过滤器的侧壁的截面视图。
相应的参考字符在附图中的数个视图当中表示相应的组件。
具体实施方式
下述说明是目前考虑实施本发明的最佳模式。这一说明不是要在限制意义上进行,而仅仅是为了描述本发明的一个或多个优选的实施方案。本发明的范围应当参考权利要求确定。
在术语“一般地”与本发明的元件(element)结合的情况下,拟描述对于人类感知的特征的外观,但不是精确的测量。
在图1中示出了中空纤维切向流过滤器30的截面视图。该中空纤维切向流过滤器30包括位于入口腔室30a和出口腔室30b之间的平行厚壁中空纤维60。入口端32a提供到达入口腔室30a的流体12,和出口端32d接收来自出口腔室30b的保留流体16。厚壁中空纤维60接收经过入口腔室30a的流体12。流体12行进通过厚壁中空纤维60的中空纤维内部60a并经过厚壁70释放渗透流体(例如蛋白质或废物材料)到过滤器外壳31的渗透物部分61内。渗透流体24前往渗透物端口32b和32c并释放或者可通过泵从过滤器外壳31中引出。过滤过的保留流体16从厚壁中空纤维60中释放到出口腔室30b内并从过滤器30经保留物端口32d释放。
在图2中示出了厚壁中空纤维切向流过滤器30的厚壁中空纤维60中厚壁70的截面视图。细胞或微载体材料74穿过厚壁中空纤维60并在保留流体16中释放。
壁70包括曲折路径71,以捕获经过厚壁中空纤维切向流过滤器30的流体12中的某些元素,同时允许其他粒子穿过进入到渗透流体24内。沉降区73和缩窄通道75捕获进入到曲折路径71内的较大细胞碎片粒子72b,同时允许较小粒子(例如,蛋白质或病毒)72a穿过。曲折路径71中的沉降区73和缩窄通道75因此引起来自渗透流体24的深度应变的粒子72b分离,这与通过常见的薄壁切向流过滤器膜的表皮或表面获得的过滤不同。
在一个实施方案中,厚壁中空纤维60优选由具有-CH2-CH2重复单元分子结构的烧结聚乙烯(PE)制造且可用PVDF包覆。中空纤维优选具有1.0mm至7.0mm和更优选约3.15mm的内径(或管腔),优选0.15cm至0.40cm,和更优选0.265cm至0.33cm的壁厚,和优选0.5μm至30μm孔尺寸的曲折路径71以供采用微载体或者在切向流过滤(TFF)或者交替的切向流(ATF)方法中在灌注和收获一种或多种哺乳动物细胞培养物中使用,从而提供材料穿过壁70的深度过滤。组装的中空纤维切向流过滤器30既是γ稳定的,且能高压釜操作。
工业实用性
本发明在过滤生物材料的领域中具有工业实用性。
本发明的范围
尽管通过本发明的具体实施方案和应用描述了本文公开的发明,但本领域技术人员可在不脱离权利要求列出的本发明范围情况下,做出许多改性和变化。
