Mass transfer device having a microporous, spirally wound hollow fiber membrane

摘要

The present invention provides a spirally wound hollow fiber mass transfer device made by winding one or more continuous microporous hollow fibers on a core such that the ratio of the pitch at which the fiber(s) are wound onto the core to the fiber band width is greater than unity and is preferably at least 2. Such a mass transfer device can be used as a blood oxygenator. The present invention also provides a method for the production of such a device.
