Specific protein analyzer and analysis method thereof

Abstract

The invention provides a specific protein analyzer and an analysis method thereof. The specific protein analyzer comprises a power element, a control apparatus, a reaction disc used for mounting of a reaction cup, a sampling needle realizes sampling or sample feeding through rotation and upward and downward motion, an arc-shaped reagent disc and a test optical path system, wherein the reaction disc comprises a reaction disc main body and a reaction cup bracket, the reaction cup bracket is provided with a plurality of reaction stations, a sample feeding position is formed at the intersection of the reagent disc and each reaction station, the test optical path system comprises a detection light source module arranged on the reaction disc main body and a signal detection apparatus, and the power element comprises a first power driving the sampling needle to rotate to a reagent position for sampling or to a sample feeding position for sample feeding, a second power driving the sampling needle to carry out upward and downward motion, a third power driving the sampling needle to carry out sampling or sample feeding and a fourth power driving the reaction cup bracket to rotate. With the specific protein analyzer and the analysis method thereof, automatic testing and high-accuracy feeding are realized, a testing speed and testing efficiency are improved, and workload of testing personnel is reduced.

Description

technical field [0001] The invention relates to a medical device, in particular to a specific protein analyzer and an analysis method thereof. Background technique [0002] The Specific Protein Analyzer is an analytical instrument used to measure the content of specific proteins in human body fluids. It uses the principle of laser scattering turbidimetry to measure the turbidity of the solution after the reaction between the sample and the reagent in the cuvette to determine the specific protein in the sample. The level of protein content and the level of specific protein content reflect the corresponding state of the patient's body and provide effective reference data for doctors to diagnose. [0003] The detection items of a specific protein analyzer generally include: glycosylated hemoglobin, urine microalbumin, β2 microglobulin, C-reactive protein, high-sensitivity C-reactive protein, anti-0, rheumatoid factor (RF), immunoglobulin IgG, IgA, IgM, complement C3, C4, album...

AI Technical Summary

Problems solved by technology

[0005] When using a specific protein analyzer to test and add samples, it is necessary to add quantitative buffer solution, sample, and antiserum to the cuvette in sequence. However, the current specific protein analyzer is manually completed, and there is a large error in sampling and adding, and the error will be too large. Directly lead to incorrect test results; slow speed and low efficiency; testers are cumbersome and prone to fatigue

Most of them are semi-automatic specific protein analyzers, whose typical feature is that a large number of manual operations need to be assisted, so there are problems of low efficiency, large errors, large amount of reagents, and high cost, and often require inspectors with high professional skills to operate

And only a single sample or reagent can be tested at a time, which greatly affects the efficiency of test analysis
