Applications of Nuclear Track Membranes to Filtration of Medical Injections and Various Transfusions to Remove Solid Particles

Nuclear track membranes produced by China Institute of Atomic Energy (CIAE) in Beijing, China, and the Joint Institute for Nuclear Research (JINR) in Dubna, Russia have been used in the studies of filtration of medical injections and various transfusion liquid medicine to remove solid particles from the medicine. It shows that the filtration devices made of nuclear track membranes are superior to that made of any other types of membranes. Experiments have demonstrated that the removal efficiencies for solid particles with diameters 5 μm can reach over 95% and the flow rate is high enough for use in medical injection and transfusion. The reproducibility of removal efficiencies and flow rate of the new devices are satisfactory to the use in hospitals. Chinese authority in medicine has approved the new devices for use in Chinese hospitals.
