Title: Innovations in Dialysis Technology: The Contributions of Richard Kruger
Introduction
Richard Kruger, an accomplished inventor based in Wuppertal, Germany, has made significant contributions to the field of medical technology, particularly in the development of advanced dialysis membranes. With a total of three patents to his name, Kruger's innovations focus on enhancing the efficiency and efficacy of blood treatment processes.
Latest Patents
Kruger's latest patents represent groundbreaking advancements in dialysis technology. One of his notable inventions is a dialysis membrane with improved removal of middle molecules. This hydrophilic semipermeable hollow-fiber membrane features an integrally asymmetric structure based on a synthetic polymer. Its unique design includes a separating layer on its inner surface and a supporting layer that is open-pored, allowing for an ultrafiltration rate in albumin solution of 5 to 25 ml/(h·m·mmHg). Additionally, this membrane is free from pore-stabilizing additives and exhibits a maximum sieving coefficient for albumin of 0.005, meeting specific standards for separating cytochrome c.
Another innovative product from Kruger is a high-flux dialysis membrane with improved separation behavior. Like the previous invention, this membrane is also a hydrophilic semipermeable hollow-fiber design, but it boasts an ultrafiltration rate of 25 to 60 ml/(h·m·mmHg) in albumin solution. Its specifications highlight a minimum sieving coefficient for cytochrome c of 0.8, along with a maximum sieving coefficient for albumin identical to his previous work.
The method for preparing such membranes includes a unique coagulation process induced by a non-solvent. This process involves extruding a spinning solution of synthetic polymers through a hollow-fiber die, which forms the necessary membrane structure. The innovative approach features an interior filler containing a polyelectrolyte with negative fixed charges, crucial for creating the separating layer within the hollow fiber.
