Abstract: The OP-Rheometer was developed to measure blood viscosity at lower shear rate (0.2–40 sec−1) and viscoelasticity at 0.1–3.0Hz in the context of clinical medicine. The system consists of a mechanical unit, a control unit, a data processing unit and a printer. The dynamic or constant flow data are automatically printed out. One of the features of this rheometer was a pair of magnetic bearings which supported an outer cylinder (blood sample container) connected to the torsion wire assembly. In clinical application, viscoelasticity of blood in diabetics showed higher level than that of normal subjects.
