Problems solved by technology

The conventional test method has major flaws. During the measurement process, repeatedly pulling out and inserting the test tube and changing the tube position number of a patient will not only prolong the test time, but also lead to misplacement of the tube position due to manual negligence. Or set the wrong pipe number, which will affect the accuracy of the test results

Embodiment 1

[0019] A method for automatically measuring blood viscosity, using an automatic blood rheometer for data collection, using a solution processor to process the data, and outputting the viscosity data of the measured blood; the blood rheometer includes a capillary viscosity measuring device , rotary blood rheology measuring device, blood mixing device, computer device; the automatic blood rheometer used in this embodiment can refer to the measuring device disclosed in Chinese Patent No. 200510092821.3, and can also adopt the LBY-N6C fully automatic Hemorheometer.

[0020] a. Collect the patient's venous blood sample for anticoagulant treatment and pour it into the sample tube, and mark the sample tube; usually about 5ml of venous blood is drawn from the vein, and anticoagulant is put in the sample tube in advance, then shake well to anticoagulate, and the patient number The mark is on the sample tube; the sample tube can also be called a test tube;

[0021] b. Using a centrifug...

Embodiment 2

[0030] This embodiment is an improvement on the basis of Embodiment 1. In this embodiment, the volume of the patient's venous blood sample is 3ml. The rotational speed of the centrifugation treatment is 1600 rpm, and the centrifugation treatment takes 4 minutes. The blood mixing device is a paddle stirrer. Since the present invention firstly measures the plasma viscosity, recovers the plasma sample, and then measures the whole blood viscosity after mixing, the amount of blood sample collection and usage is reduced, which can be reduced from the traditional blood collection volume of 5ml to 3ml. The collection of blood samples with a volume of 3ml can reduce the loss and pain of patients and reduce the amount of medical waste to be processed.

Abstract

The invention relates to a method for automatically measuring blood viscosity, which comprises the following steps of: acquiring data by using a full-automatic blood rheometer, wherein the blood rheometer comprises a capillary viscosity measuring device, a rotary blood rheology measuring device and a blood mixing device; centrifuging a blood sample by using a centrifugal machine to completely separate blood cells from blood plasma; starting the capillary viscosity measuring device to measure the viscosity of a blood plasma sample; re-injecting the used blood plasma sample into a sample tube; uniformly mixing the blood samples into a whole-blood state; starting a sampling needle to suck the whole blood from the sample tube and injecting the whole blood into the rotary blood rheology measuring device, and measuring the viscosity of the whole blood; and processing the measured data by using a resolving processor to generate a measuring report. The method for automatically measuring the blood viscosity eliminates manual operation error, simplifies operation steps, and shortens test time.

Description

technical field [0001] The invention relates to a method for automatically measuring blood viscosity. The method uses a centrifuge to centrifuge the collected blood sample at a low speed, and uses a capillary viscosity measuring device to measure the viscosity of the plasma sample; then injects the used plasma sample back into the sample tube, and The blood sample is mixed into a whole blood state, the whole blood is drawn from the sample tube, and the viscosity of the whole blood is measured using a rotary hemorheology measuring device. Background technique [0002] Chinese patent 200520103130.4 discloses a method for measuring whole blood viscosity and plasma viscosity. In the field of medical testing, a hemorheometer is mainly used for testing whole blood viscosity and plasma viscosity. Whole blood viscosity is a non-Newtonian fluid, and the more reasonable method usually adopted is the rotation method, and the equipment used is a fully automatic hemorheometer. Plasma be...
