MONOFILAMENT SPACING OF HOLLOW FIBER MEMBRANES AND BLOOD OXYGENATION DEVICES INCORPORATING SAME

摘要

Disclosed are improved hollow fiber semipermeable membranes having monofilamentous spacer members spirally disposed or formed on the outer surface thereof, and extracorporeal blood treatment devices incorporating such improved hollow fiber membranes. Also disclosed are methods for manufacturing the hollow fiber membranes and a continuous method for manufacturing a blood processing apparatus which incorporates the hollow fiber membranes.
