Full-automatic dynamic erythrocyte sedimentation rate analyzer based on Westergren's method

Abstract

The invention discloses a full-automatic dynamic erythrocyte sedimentation rate analyzer based on a Westergren's method. The analyzer comprises a bottom plate; a sample injection frame module for driving a sodium citrate tube and an EDTA tube to automatically inject samples, a shaking-up module for automatically and uniformly mixing samples, a needle washing pool for washing a sampling needle, a sample adding module for adding a sample in the sample tube into a detection tube for detection, a control panel for operating an instrument and outputting a result, a turntable module, a power inputswitch, an external communication board for transmitting detection data, a filling and cleaning module for adding a sample into the detection tube, a liquid path module for cleaning, diluting and treating waste liquid, an external PCB control module, and a rack are installed on the bottom plate. The test process is processized and standardized, the test principle is the same as that of a standardWestergren's method, various interference factors of manual operation are avoided as much as possible, and the test result is objective, reliable and credible; the development of erythrocyte sedimentation rate detection in the directions of reliability, accuracy, convenience and the like is facilitated, and the test efficiency is remarkably 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 i
