    • A concentrator for concentrating the fine solids of a liquid feed suspension has a shell within which there is a bundle of microporous fibers. Pressurized feed suspension is introduced through an inlet and passes over the external walls of the fibers with the clarified liquid being drawn from the lumens of the fibers and the concentrated feed being discharged through an outlet. The solids retained within the shell are removed by first applying a pressurized liquid and then applying a gas at a pressure sufficient to ensure that the gas will pass through the larger pores of the fibrs to remove the solids from the shell through the outlet to an external collection point. The fibers are enclosed within a variable volume diaphragm located within a diaphragm holder by spaced plugs. The volume of the diaphragm is altered by varying the pressure of a fluid introduced through the inlet to the space between the diaphragm and the diaphragm holder.

    • There is disclosed herein an apparatus and method for preparing a continuous, hollow, and semipermeable filament for use in a dialyzer which includes a plurality of substantially-equal-length open-ended fibers.The apparatus includes a body having a supply spool of filament and a take-up reel having at least two radially-spaced support means about which the filament is wound. Drive means rotate the take-up reel and a filament guide is provided for laterally positioning the filament on the support member so as to prevent close packing of the filament windings. The take-up reel includes a winding plate for carrying the filament support means and hub-and-locking means for releasably mounting the winding plate on the machine.The method includes winding the filament from the spool onto the take-up reel; grasping each of the sections of filament between the support means; and cutting the filament adjacent the support means so as to form a plurality of bundles of open-ended fibers for use in a hollow fiber dialyzer.
    • 本文公开了一种用于制备用于透析器的连续的,中空的和半透膜细丝的装置和方法,该透析器包括多个基本上相等长度的开口端的纤维。 该装置包括具有细丝供应卷轴的主体和具有至少两个沿径向间隔开的支撑装置的收卷卷轴,细丝缠绕在该支承装置上。 驱动装置旋转卷取卷轴,并且提供细丝引导件用于横向地将长丝定位在支撑构件上,以防止细丝绕组的紧密堆积。 收纸卷轴包括用于承载灯丝支撑装置的卷板和用于将卷板可释放地安装在机器上的轮毂锁定装置。 该方法包括将丝线从卷轴卷绕到卷带盘上; 抓住支撑装置之间的细丝部分; 并且在所述支撑装置附近切割所述细丝以便形成多个用于中空纤维透析器的开口纤维束。
