ESR (erythrocyte sedimentation rate) detection device and detection method thereof

Abstract

The invention belongs to the field of blood sedimentation detection, and particularly relates to an ESR (erythrocyte sedimentation rate) detection device and a detection method thereof. The problems that an existing Westergren method for detecting ESR is complex, time and labor are wasted, an ESR instrument detection instrument is high in cost and large in structure, miniaturization and portability are difficult to achieve, an inclined tube method is only applied under specific conditions, and the detection quality is not high are solved. The ESR detection device is composed of a detection module, a control module and a display module. Based on the bioelectrical impedance detection principle, the T-shaped container is adopted as a container for detecting blood to be detected, the ESR detection result is obtained by detecting voltage and current signals in the sedimentation process and calculating the real-time impedance value, and the method is wide in applicability, high in accuracy,rapid, efficient, capable of monitoring the ESR process in real time; the device is simple structure; miniaturization and portability of ESR detection can be achieved conveniently, and the device canbe widely applied to the field of health care.

Description

technical field [0001] The invention relates to the field of biomedical detection, in particular to an erythrocyte sedimentation detection device and a detection method thereof. Background technique [0002] The erythrocyte sedimentation rate refers to the index of erythrocyte sedimentation velocity under certain conditions, referred to as erythrocyte sedimentation rate. The erythrocyte sedimentation rate of a healthy person usually fluctuates up and down within a relatively narrow range, and there will be no large ups and downs. However, under the interference of many cases, the erythrocyte sedimentation rate will show a significant increase. Measuring erythrocyte sedimentation rate is widely used clinically. Comparing the results of erythrocyte sedimentation rate with clinical data shows that erythrocyte sedimentation rate has many clinical applications, which can assist in judging whether there is inflammation in the patient's body, whether the patient's lesions are activ...

AI Technical Summary

Problems solved by technology

[0003] Widmanner's method is the most classic, traditional, conventional, and reliable method for detecting erythrocyte sedimentation rate. It is also a routine method recommended by the International Hematology Standardization Committee. It can only measure the final result of erythrocyte sedimentation rate at a certain moment, with poor specificity, its application has great limitations, and there are relatively strict requirements for the time of observation and recording

In recent years, people have been looking for a simpler and less troublesome method of measuring erythrocyte sedimentation rate. The more familiar method is to use an erythrocyte sedimentation meter, which can dynamically record the changes in the entire erythrocyte sedimentation process, draw a curve of erythrocyte sedimentation, and reflect different diseases or diseases. Different stages of diseases, although this method is more convenient, and the detection time is not long, but the test results obtained are affected by many external factors, and the cost of the instrument is relatively high, not all hospitals can popularize it, and the volume of the instrument big, not portable

The inclined tube method can speed up the erythrocyte sedimentation rate, shorten the test time, and the result can be obtained in only 15 minutes. Compared with the Weiss method, it can greatly reduce the patient's waiting time, and the blood volume can be reduced by 1 / 3 compared with the Weiss method. However, there are still deficiencies. It cannot be completely compared with Wei's method, and it is only suitable for patients with elevated erythrocyte sedimentation rate under certain conditions, which has great limitations. It is also impossible to monitor changes in the erythrocyte sedimentation process
