ABSTRACT:
A membrane module for hemodiafiltration having a cylinder-shaped housing and a bundle of hollow-fiber membranes capable of supporting fluid flow and arranged in the direction of the longitudinal extent of the housing. The ends of the hollow-fiber membranes are embedded in a fluid-tight manner in first and second sealing compounds joined to the housing inner wall in a fluid-tight manner. The exterior space formed around the hollow-fiber membranes and delimited by the first and second sealing compounds and the housing inner wall is divided along the longitudinal extent of the housing into a dialyzate space and a substituate space by a dividing wall that is made from a substantially dimensionally stable material. The dividing wall encloses each hollow-fiber membrane and is arranged substantially transversely to the hollow-fiber membranes. The dialyzate space and substituate space each have at least one opening for introducing or draining a fluid. In the exterior space, at least one throttle is arranged by which the dialyzate space and substituate space are in fluid communication with each other.
