Hollow fiber device for removing waste material in the blood and a process of manufacture thereof

摘要

A method of manufacturing a medical hollow fiber device for removing waste material in the blood, including the steps of providing a housing; coiling hollow fiber membranes into loops; providing bundles of the loops whose entire interior is filled with a liquid and placing them into the housing; closing both ends of the housing with caps; supplying viscous potting material into the housing at the end portions of the hollow fiber membranes, and applying a centrifugal force to the housing. The potting material penetrates between the end portions and exerts an outside pressure on the membranes. The liquid in the membranes moves toward both ends of the housing and exerts an inside pressure overcoming the outside pressure of the potting material until the potting material solidifies.
