hat features must a rheometer have to measure blood viscoelasticity?
The measurement of blood viscoelasticity requires oscillatory measurements with high precision and sensitivity. Conventional rotational rheometers cannot meet these requirements. A rheometer must be able to operate at frequencies near the pulse rate. A well designed rheometer should also require small sample volumes, minimally expose the operator to the blood sample and be simple to operate. A rheometer designed for the measurement of blood must meet the unique challenges posed by blood.
