Paper Abstract

This paper presents a dual magnetic circuit magnetic bead method and corresponding system for testing human blood coagulation. The system is composed mainly of a dual magnetic circuit magnetic beads test assembly, a signal modulation and demodulation module, a digital filter as well as a waveform processor. Smart hardware design together with subsequent software algorithm is presented for the system to overcome the defects of traditional dual magnetic circuit magnetic bead method. Experiments for verifying the system are carried out in comparison with an ACL200 coagulometer from Coulter Co. USA. Experimental results indicate that the system features excellent precision, repeatability better than 2.10%, and show that the dual magnetic circuit magnetic bead system suppresses external interference factors effectively.
