Description

A kit for measuring blood viscosity}

The present invention relates to a kit for measuring blood viscosity, and more particularly, comprising an upper sample holder coupled to an upper plate of a rheometer and a lower sample holder coupled to a lower plate of the rheometer, and storing blood in the upper sample holder and It relates to a blood viscosity measurement kit, characterized in that the blood viscosity measurement kit is detached from the rheometer and used for a single use after measuring the viscosity of blood by placing it in close contact between the lower sample holders.

Rheometer is a general term for measuring rheological properties of pastes, gels, liquids, etc., and various properties such as viscosity, viscoelasticity, plasticity, yield stress, and stress relaxation behavior of fluids can be analyzed through the rheometer.

These rheometers can be used in various industrial fields such as polymers, ceramics, food, paints, coatings, and cosmetics, and are largely classified into rotational rheometers and capillary rheometers.

The rotational rheometer loads a sample between two plates, and when a torque is applied to the upper plate or the lower plate, the sample is deformed as a rotational shear stress is applied to the sample.At this time, various information can be obtained by measuring the behavior of the sample. .

The capillary rheometer exerts a force on the sample under high pressure to discharge the sample through the die. At this time, the behavior of the fluid can be measured by measuring the pressure drop of the sample.

Rotational rheometers are preferable to observe fluid behavior at low shear rates of 1 to 10 s ^{- 1} , whereas capillary rheometers are preferable to analyze at high shear rates ^{of 100 s −1 or more.}

Meanwhile, for blood analysis, blood is placed between the upper plate and the lower plate of the rheometer, and then the rheometer is operated to measure the viscosity.At this time, the contact surfaces of the upper plate and the lower plate are contaminated by blood, which causes errors when measuring the viscosity later. Can result.

In addition, it is cumbersome to clean the contact surface between the upper plate and the lower plate each time the measurement is performed, and the contact surface may be contaminated by washing, which may affect the viscosity analysis later.

Therefore, there is a need for a kit for measuring blood viscosity that can be easily used without contaminating the upper and lower plates of the rheometer when measuring the viscosity of blood.
