Improved hollow fiber membrane device with inner wrap.

摘要

A hollow fiber membrane device characterized by employing an inner constraining wrap (15) extending no farther than 25 percent of the diameter of the hollow fiber bundle (17) from the central, longitudinal axis of the bundle. The fibers (6) within the inner wrap (15) are not necessarily hollow. Optionally, an elastic outer wrap (9) is also employed about the bundle.
