摘要： A process for the production of hydrophilic membranes using at least one hydrophobic polymer and polyvinyl pyrrolidone as a hydrophilic polymer, membrane-forming shaping of the polymers and immobilization of the polyvinyl pyrrolidone is characterized in that the polyvinyl pyrrolidone is immobilized on and/or in the membrane by treatment with an aqueous solution of peroxodisulphate in a hot condition. The solution of peroxodisulphate is kept substantially free of oxygen during immobilization by degassing the solution. The membranes are used for hemodialysis, hemodiafiltration and hemofiltration of blood.

摘要： A method for manufacturing a filter device having filter means, in particular hollow-fibre membranes, arranged in more than one filtration compartment within a filter housing. For example a dialysis type filtration process such as haemofiltration or haemodiafiltration or haemodialysis may be carried out at the same time as an ultrafiltration process or as another haemofiltration, haemodiafiltration or haemodialysis process. A split shell is bonded or welded together along longitudinal seams. Internal separating walls within the housing are formed integrally with the shell portions of the housing to form adjacent filtration compartments when the housing portions are joined together.

摘要： A filter device having filter means, in particular hollow fiber membranes, arranged in more than one filtration compartment within a filter housing. The filter device thereby allows more than one filtration process to be carried out serially and/or simultaneously within a single housing. For example a dialysis type filtration process such as hemofiltration or hemodiafiltration or hemodialysis may be carried out at the same time as an ultrafiltration process or as another hemofiltration, hemodiafiltration or hemodialysis process. The device may have a split shell construction bonded or welded together along longitudinal seams. Internal separating walls within the housing are formed integrally with the shell portions of the housing to form adjacent filtration compartments when the housing portions are joined together.

摘要： Methods and apparatus are disclosed for producing hollow fiber membrane-containing filters. The methods include laying a plurality of hollow fibers in a first portion of a filter housing to form a bundle, forming first and second portions into a filter housing, sealing the portions together, connecting the plurality of hollow fibers together at at least one end of the filter housing, connecting the hollow fibers to the filter housing, and simultaneously adhering the first and second portions of the filter housing together by applying a potting compound thereto, and cutting the ends of the hollow fibers at at least one end thereof, whereby the hollow fibers include open ends.
