A fully automatic dynamic erythrocyte sedimentation analyzer based on Wei's method

Abstract

A fully automatic dynamic erythrocyte sedimentation analyzer based on Wei's method, including a base plate, a sample rack module for driving automatic sampling of sodium citrate tubes and EDTA tubes, a shaking module for automatic sample mixing, a cleaning and adding Needle washing pool for sample needles, sample adding module for adding samples from sample tubes to detection tubes for detection, control panel for operating instruments and outputting results, turntable module, power input switch, external communication for transmitting test data Plate, filling and cleaning module for adding sample to the detection tube, liquid circuit module for cleaning, diluting, and waste liquid treatment, external PCB control module and rack. The test process is streamlined and standardized. The test principle is the same as the standard Weiss method, and various interference factors of human operation are avoided as much as possible. The test results are objective, reliable and credible; it is conducive to promoting the reliability and accuracy of ESR detection. Developed in the direction of performance and convenience, the test efficiency has been significantly improved.

Description

technical field [0001] The invention relates to the technical field of erythrocyte sedimentation analysis, in particular to a fully automatic dynamic erythrocyte sedimentation analyzer based on the Wei's method. Background technique [0002] Erythrocyte sedimentation rate (ESR) is a commonly used reference index for certain diseases. ESR test is used for the diagnosis and treatment of various diseases such as inflammation, tissue damage and necrosis, malignant tumors, hyperglobulinemia, anemia, and hypercholesterolemia. It has certain reference value. [0003] As the erythrocyte sedimentation detection method designated by the International Committee for Blood Standardization, the Wei's method is the gold standard for erythrocyte sedimentation detection. The measurement results of Wei's method are accurate, but the operation is complicated, the work efficiency is low, the error of manual interpretation is large, and there are biological hazards. Now most hospitals use auto...

Problems solved by technology

The measurement results of Wei's method are accurate, but the operation is complicated, the work efficiency is low, the error of manual interpretation is large, and there are biological hazards

Now most hospitals use automatic erythrocyte sedimentation meter to replace traditional manual operation, but nowadays there are more and more styles of erythrocyte sedimentation meter and more and more detection methods, which cause certain problems to the comparability and reliability of erythrocyte sedimentation rate results

At present, the instruments on the market are basically semi-automatic measuring instruments. Compared with Wei's method, by changing the inner diameter of the erythrocyte sedimentation tube, the angle of inclination, the height of blood collection, and short-term prediction of the result in one hour, the detection speed can be improved or the blood collection volume can be reduced. The literature shows that No guarantee of full-scale correlation with Widmansler's method

Moreover, a separate tube of sodium citrate anticoagulant blood needs to be collected for erythrocyte sedimentation rate, and EDTA anticoagulant blood collection tubes for blood routine testing cannot be used, which not only brings additional pain to patients, but also increases the use of blood collection tube consumables
