A new model of approximation of the blood-flow curve with 
five parameters independent of the hematocrit and the rate of shear 
is proposed. On the basis of the statistical analysis, we have shown 
the reliability of differences of the mean values of the independently 
measured aggregatability and deformability of erythrocytes and the 
parameters of the new rheological model of hematological patients 
(myeloma, erythremia, anemia, blood loss) from donors. The relation 
of two parameters of the model, 1 and 3 , to the aggregatibility and deformability of erythrocytes, respectively, has been proved.
