Outline of Final Research Achievements |
The real-time detection of blood coagulation is important in various extra-corporeal circulation devices like hemodialyzer, heart-lung-machine and ventricular assistance devices. In this study, we developed a coagulation detection system based on measurement of electrical properties of blood under thrombosis formation. An electrical parameter called characteristic frequency of blood was useful in the coagulation monitoring. This finding was verified by comparing the results against conventional analysis method like activated clotting time (ACT) readings. Further analysis of the measurement readings, showed that the remarkable change in the electrical characteristic frequency of blood coincided with the the conversion of the soluble Fibrinogen to Fibrin monomers. This effect, along with other biophysical changes during blood coagulation on the electrical properties of blood, was also analyzed by computational methods in addition to experimental methods.
