摘要： There is disclosed a blood viscosity measurement device which measures a flow rate of blood and a thickness of a blood vessel to determine a viscosity of the blood. The device substitutes the flow rate of the blood, the thickness of the blood vessel, and a blood pressure into a predetermined calculation formula to calculate the viscosity of the blood. The flow rate of the blood is obtained from a change amount of frequency of a continuous ultrasonic wave transmitted to a blood flow and reflected by the blood flow. As to the thickness of the blood vessel, an inner diameter of the blood vessel is obtained from a pulse ultrasonic wave transmitted to the blood vessel and reflected by an inner wall of the blood vessel. On the other hand, a value measured with a general blood pressure gauge is utilized in the blood pressure. The blood viscosity measurement device substitutes the maximum flow rate, the maximum inner diameter, and the maximum blood pressure among the values acquired as described above into the calculation formula to calculate the viscosity of the blood.
