Abstract:
1. A membrane module for hemodiafiltration, comprising a cylinder-shaped housing with a longitudinal extent, and in the housing a bundle of hollow-fiber membranes with semipermeable walls and capable of supporting fluid flow through lumina is arranged in a direction of the longitudinal extent of the housing, one end of the hollow-fiber membranes being embedded in a fluid-tight manner in a first sealing compound joined to a housing inner wall in a fluid-tight manner and a second end of the hollow fiber membranes being embedded in a fluid-tight manner in a second sealing compound joined to the housing inner wall in a fluid-tight manner, wherein an exterior space delimited by the first and second sealing compounds and the housing inner wall is formed around the hollow-fiber membranes, the exterior space along the longitudinal extent of the housing being divided into a dialyzate space and a substituate space by a dividing wall comprising a substantially dimensionally stable material, enclosing each of the hollow-fiber membranes, and arranged substantially transversely to the hollow-fiber membranes, the dialyzate space and substituate space each having at least one opening for introducing or draining a fluid, wherein at least one throttle is arranged in the exterior space by which the dialyzate space and substituate space are in fluid communication with each other.
