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

Abstract

The invention relates to a full-automatic Westergren's method-based erythrocyte sedimentation rate analyzer. A sample injection frame module is arranged on the foremost side of the analyzer, a shaking-up module is arranged in the middle spare position of the sample injection frame module, a code scanning device is arranged on one side of the sample injection frame module, and a liquid path modulefor sucking samples, diluent and cleaning liquid is installed on one side of a bottom plate; a pipe placing frame module for placing a measuring pipe and driving the measuring pipe to rotate is mounted on the bottom plate; a cleaning position lifting module for pushing and pulling a piston in the measuring pipe to realize the functions of extracting cleaning liquid and releasing the liquid is mounted on one side of the pipe placing frame module; a cleaning nozzle is correspondingly arranged under the cleaning position lifting module, and a detection lifting module is arranged on one side of the pipe placing frame module; a puncture sampling module is of a double-needle structure and comprises an outer needle for puncture and an inner needle for sample suction. The erythrocyte sedimentationrate analyzer is fully automatic, thereby liberating the manpower of a laboratory technician in a laboratory, and reducing the errors of manual operation and reading; and with an advanced infrared liquid level reading technology, the measurement result is more accurate.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a fully automatic Wei's method erythrocyte sedimentation analyzer. 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 automatic erythrocyte sedimentation meter to replace...

AI Technical Summary

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
