Abstract:
A system for effecting the measurement of the viscosity of circulating blood of a living being at plural shear rates, said system comprising a column having a liquid therein, a capillary tube, a sensing device and viscosity calculation means, said liquid in said column having a top surface, said capillary tube being arranged to be inserted into the vascular system of the being for providing blood from the being to cause said liquid in said column to assume an initial level, said column being operative so that said liquid in said column is enabled to drop from said initial level to a lower level, said sensing device for monitoring the height of the liquid in the column at plural points along the column as said liquid drops in said column and for providing electrical signals indicative thereof, said calculation means being coupled to said sensing device for receiving said electrical signals to calculate the viscosity of the being's blood.
