Micro-Viscometer for Measuring Shear-Varying Blood Viscosity over a Wide-Ranging Shear Rate
In this study, a micro-viscometer is developed for measuring shear-varying blood viscosity over a wide-ranging shear rate. The micro-viscometer consists of 10 microfluidic channel arrays, each of which has a different micro-channel width. The proposed design enables the retrieval of 10 different shear rates from a single flow rate, thereby enabling the measurement of shear-varying blood viscosi...
متن کاملThe criteria for evaluating shear stress measuring range and the lowest measurable shear stress of rotational viscometer.
In the Guidelines for measurement of blood viscosity and erythrocyte deformability by ICSH in 1986, it points out that the viscometer for hemorheology should ideally be able to operate over a wide range of shear conditions, and for a constant shear-rate viscometer a high-shear measurement at 200/second and a low-shear measurement at 1/second (or shear-rates approximating to these values if they...

متن کاملProcedure to Evaluate the Shear Rate Profile and the Apparent Viscosity of Non-newtonian Fluids in the Falling Cylinder Viscometer
−− The falling cylinder viscometer (FCV) is a reliable instrument to quantify the viscosity of Newtonian fluids. Nevertheless, when nonNewtonian fluids are tested in this device, difficulties appear to determine the apparent viscosity. Thus, conventional rheometric calculations cannot be applied directly to experimental data provided by the FCV in order to obtain the apparent viscosity function...
متن کاملShear rate specific blood viscosity and shear stress of carotid artery duplex ultrasonography in patients with lacunar infarction
BACKGROUND This study describes a new method for determining site-specific vascular shear stress using dynamic measures of shear rate and blood viscosity (BV) in the carotid arteries, and examines characteristics of carotid arterial shear stress among patients with lacunar infarction. METHODS Vascular shear stress measurements were conducted in 37 patients (17 lacunar infarction patients and ...
