3 Terms and Definitions

3.1 shear rate shearrate Liquid flow shear strain rate change with time. 3.2 shear stress shearstress Internal friction per unit area between the liquid layer adjacent to the liquid flow. 3.3 whole blood viscosity wholebloodviscosity The ratio of shear stress to shear rate of blood flow stratification. 3.4 plasma viscosity plasmaviscosity The ratio of shear stress to shear rate of plasma stratified flow. 3.5 minimum shear stress minimumshearstress Instrument at a constant shear rate and climate conditions can be accurately measured minimum shear stress.

4 Overview

Blood viscometer is based on Newton's law of viscosity, measured in whole blood at specified shear rates, the viscosity of plasma resistance, Obtain blood plasma viscosity and apparent viscosity of the instrument. Newton's law of viscous mathematical expression is. η = · (1) Where. η --- fluid dynamic viscosity, mPa · s; [tau] --- shear stress, mPa; --- · Shear rate, s-1. General Instrument by the drive system, speed control system, torque and torque measurement systems, positioning systems, thermostats, and samples Sensing measurement systems, data processing and display system components, shown in Figure 1. ...
