ABSTRACT

Objective:

To develop a novel fast auto blood viscosity analyzer based on the relation between flow rate and Casson viscosity of non-Newton fluid such as blood.

Methods:

Different from the tradition friction method of measuring blood viscosi-ty, the instrument was developed based on the Casson flow equation for blood in round tube and Stokes equation, using virtual instrument technique to calculate the Casson viscosity and stress, and pressure sensor and peristaltic pump to perform a setup.

Results:

Controlled by the data acquisition system, the blood Casson viscosity and stress were measured quickly and simply.

Conclusions:

Compared with the similar instruments used in clinic, this analyzer is faster in measurement and has high preci-sion, can determine the apparent viscosity and other Casson parameters of blood at any shear rate, and gives more clinic informa-tion for patients.
