Title: Innovations by Raymond Elsen in Membrane Technology
Introduction
Raymond Elsen is an accomplished inventor based in Miami Lakes, FL (US). He has made significant contributions to the field of membrane technology, particularly in the development of high-flux hollow-fiber membranes. With a total of 2 patents, his work focuses on enhancing the purification of biological fluids, which is crucial for medical applications.
Latest Patents
Elsen's latest patents include a high-flux hollow-fiber membrane with enhanced transport capability and semipermeable membranes designed for purifying aqueous biological fluids. These membranes are particularly suitable for extracorporeal blood purification via hemodialysis. They are made from a hydrophilic polymeric material, specifically cellulose acetate. Key features of these membranes include an ultrafiltration coefficient (K.sub.uF) ranging from about 15 to about 55 mL/hr/mmHg/m², and a urea mass transfer coefficient (K.sub.oV (Urea)) of at least 38×10⁻³ cm/min. The design of the hollow fibers allows for a lumen diameter of approximately 175 to 210 µm and a wall thickness of about 10 to 35 µm. The manufacturing process involves extruding a melt of cellulose acetate, glycerine, and polyethylene glycol to create the hollow fibers, which are then processed through cooling, cold-stretching, water-leaching, and re-plasticization.
