摘要： A medical tube characterized in that it dilates at its cut ends toward the external surface when it is cut at any random portion transversely relative to its longitudinal direction.The patency of the sutured portion may be maintained in good condition over a long time, since pannus formation in the internal cavity can be obviated at the sutured portion between an organ of a living body and an artificial medical tube.

摘要： A hollow-fiber permeability apparatus includes a housing having a permeating region, a bundle of permeable-wall hollow fibers in the permeating region, means for supplying a first fluid flowing between the exteriors of the fibers, another means for passing a second fluid through the interiors of fibers such that materials selectively permeate through the walls of the fibers, and an enlarged cross-section portion to define at least one compartment between the bundle and a wall of the housing and having an inlet opening for introducing the first fluid into the housing, the permeating region having a flattened cross-section in the direction substantially perpendicular to the lengthwise direction of the fibers, and the enlarged cross-section portion being formed at least along substantially the whole lengths of the longer side of the cross section of the permeating region.
