Abstract

A hollow fiber filter device for dialysis having a housing and an end cap is described. The end cap is attached to an axial end of the housing, and has a curved channel in fluid communication with a fluid port, a fluid chamber having a flow path defined by a plurality of curved members connected to an upper interior surface. The distance between circumferentially adjacent curved members may decrease in a radially outward flow direction.
