Problems solved by technology

[0003] The rotational viscometer in the prior art is a testing device recommended by the International Council for Standardization in Haematology (ICSH) to measure the rheological properties of fluids. By selecting different shear rates, it can measure The apparent viscosity of the measured fluid at different shear rates is scanned point by point to draw the hemorheological characteristic curve of the fluid viscosity as the shear rate changes. Therefore, the rotary viscometer is used to measure non-Newtonian fluids (whole blood Viscosity) ideal equipment, but this equipment can not realize the measurement of the viscosity of Newtonian fluid

Abstract

The invention relates to a blood viscosity acquiring method and system. The method comprises the following steps: using a microprocessor to instruct an electromagnetic driving device to drive a cassette mechanism to rotate, thereby driving a disc and a cone to rotate at an accelerated speed by the cassette mechanism; using the microprocessor to instruct the electromagnetic driving device to stop driving when determining that the rotation speed of the cone reaches a preset first switching rate, thereby driving the disc and the cone to rotate at a decelerated speed by the cassette mechanism; using the microprocessor to instruct a photoelectric sensor to acquire the rotation angular velocity and the angular acceleration of the cone in the process of rotating at the decelerated speed; and acquiring the viscosity of the sample according to the rotation angular velocity and the angular acceleration. By using the embodiment of the invention, the influence on the viscosity of the sample caused by a frictional force generated between the electromagnetic driving device and the disc is avoided, the accuracy of the viscosity of the sample is increased, and the measurement for the viscosities of Newtonian fluid and non-Newtonian fluid under the condition of a determined switching rate is realized.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a blood viscosity acquisition method and system. Background technique [0002] Blood viscosity is one of the many indicators that need to be measured in hemorheology, mainly reflecting changes in blood fluidity, coagulation and blood viscosity due to changes in blood components; the most typical disease with increased blood viscosity is huge Gammaglobulinemia, multiple myeloma, hyperlipidemia, hyperglobulinemia, hypertension, etc.; therefore, regular plasma testing is of great significance for the prevention or early detection and early treatment of vascular diseases. [0003] The rotational viscometer in the prior art is a testing device recommended by the International Council for Standardization in Haematology (ICSH) to measure the rheological properties of fluids. By selecting different shear rates, it can measure The apparent viscosity of the measured fluid at diffe...
