A coating layer containing a silicone compound is formed on an inner surface of a hollow fiber membrane for manufacturing an oxygenator having a plurality of porous hollow fiber membranes for gas exchange. The method includes dissolving a silicone compound in an organic solvent having a surface tension of less than 70 dyn/cm to prepare a coating solution; and bringing an inner surface of the hollow fiber membranes into contact with the coating solution while bringing an outer surface of the hollow fiber membranes into contact with water to form a coating layer containing a silicone compound on the inner surface.

The invention provides a method and a device for manufacturing a hollow fiber membrane module. The present invention, by penetrating the hollow fiber membrane wires into the steel wires and performing rigidization treatment, greatly improves the rigidity of the hollow fiber membrane wire module, thereby avoiding the bending and deformation of or the damage of hollow fiber membrane wire module due to a small force during the production process, which greatly improves the production efficiency of the hollow fiber membrane module. The device of the present invention is used to achieve the above-mentioned method.

The present invention concerns a filtration membrane bundle (30) comprising a plurality of elongated filtration fibers (40) arranged in a spiraled coil (34); and one or more filaments (50) woven around the plurality of elongated filtration fibers (40) binding one or more adjacent elongated filtration fibers (40) at a predetermined and homogeneous spacing (44,48) from one another wherein each elongated filtration fiber (40) is bound to respective adjacent elongated filtration fibers (40) in a co-planar configuration, and wherein the co-planar configuration of filtration fibers (40) are rolled into a coil (34). Furthermore, a filtration membrane assembly comprising the filtration membrane bundle (30) and a housing and method of providing the filtration membrane bundle (30) are disclosed.

A method for forming a ceramic membrane module system includes disposing at least one membrane (118) within a housing (120), the membrane (118) having capillaries therein. The method includes sealing the first housing end (122) and capillaries, applying force to the removable gasket with an external frame assembly (200), and disposing potting material into the housing (120) without plugging the capillaries with the potting.

The present disclosure relates to processes for the production of capillary dialyzers. The processes involve contact-free thermoforming of bundles of hollow fiber membranes. The present disclosure also relates to an apparatus for contact-free thermoforming of bundles of hollow fiber membranes.

The present disclosure relates to a filtration device comprising a plurality of hollow fiber membranes, a process for its production, and its use for the dead-end filtration of infusion liquids.

The present disclosure describes a device and method to clear solutes from a patient's blood while maintaining fluid balance. In some implementations, the device and method is used to assist the filtration functions of a patient's liver or kidney. The device includes a plurality of hollow fibers that pass through a sequence of alternating filtration chambers and infusion chambers. The filtration chambers filter the patient's blood while the infusion chambers rehydrate the filtered blood.
