[Development of the coaxial-cylinders-type coagulometer].

Through the detection of the change of shear stress in blood, four coagulation parameters (t(r), delta tau/delta t, tau(max), S) can be automatically determined. The instrument can be used to automatically detect the process of blood coagulation and print coagulation curves. There is a great difference between different samples while there is a good repeatability with the same sample.
