Abstract
A hollow fiber medical separatory device of the type including a shell containing a plurality of hollow semi- permeable fibers extending through a central dialysate chamber and terminating in spaced apart blood chambers comprises tubesheets at each end of the fibers having the shape of a frustrum of a cone and sized such that the fibers fill the cone to the peripheral edge at the outer end planar surface of the frustrum; and a multi-functional blood chamber means forming a blood chamber by pressure sealing engagement with the outer tapered surface of the cone and also pressure sealed to the outer end surface of the shell to prevent air ingress into the dialysate chamber during testing or use. The invention also includes a method for potting the frusto-conical tubesheets on the end portions of the fibers while the fibers are positioned in the shell using steps and means to insure centering of the fibers in the cone during centrifugal casting of the resin.
