[Study of an in-vivo and real-time method to measure blood viscosity]

The traditional methods to measure blood viscosity are out-line. They have the disadvantages of long measurement time, many disturbance factors during measurement, the damage to blood sample, and etc. So rapidity, accuracy and repeatability are not satisfactory. A new method to measure blood viscosity is proposed in this paper, which uses needle instead of capillary and can measure blood viscosity during collecting blood. Owing to the advantages of small amount of blood sample, rapidity and repeatability, the new method is of value for clinical application.
