The invention discloses an intelligent blood stagnation state detection device. A system comprises a detection unit and a rotary unit located below the detection unit; the viscosity of blood is detected through a time-difference-division and frequency-division detection method. The intelligent blood stagnation state detection device has the advantages that the system is simple, stable and reliable; basic oscillation frequency can be detected, so that the calibration is convenient; a totally digital circuit has relatively low requirements on a power supply; the manufacturing cost of equipment is low and the properties are stable.
