Full-automatic external detection equipment and method for measuring specific egg white by turbidimetry

Abstract

The invention discloses full-automatic external detection equipment and method for measuring specific egg white by turbidimetry. The full-automatic external detection equipment comprises a detecting platform, a mechanical arm and a loading pump which are arranged on the detecting platform, a sample adding needle on the detecting platform, and a washing device which is arranged on the detecting platform and is used for washing the sample adding needle, wherein the detecting platform is provided with a plurality of photoelectric detection modules with temperature control and stirring functions, and the photoelectric detection modules are provided with a plurality of reaction cups; the loading pump is connected with the sample adding needle. The full-automatic external detection equipment and method provided by the invention have the advantages that the full-automatic loading of a first detection reagent, a sample to be detected and a second detection reagent are realized, so that the manual loading operation is omitted, the labor cost of the external detection is saved, and a condition that faults in an operation of manually and dropwise adding the detection reagent influence the detection result is also avoided as far as possible; meanwhile, the detection efficiency is improved, the detection time is shortened, and thus the full-automatic external detection equipment has wide market prospect.

Description

technical field [0001] The invention relates to in vitro diagnostic equipment, in particular to a fully automatic in vitro detection equipment and method for measuring specific proteins by turbidimetry. Background technique [0002] The so-called specific proteins refer to those special proteins that have certain physiological functions in the body and play important pathological significance in disease states. Detection of these specific proteins can often determine the physiological condition of a patient's body. Existing specific proteins can be used for clinical detection of the following: immune dysfunction (detection of IgA, IgG, IgM, complement C3, complement C4, kappa light chain, lambda light chain); inflammation status monitoring (detection of C-reactive protein, alpha acid sugar protein, haptoglobin, ceruloplasmin); rheumatoid disease (detection of rheumatoid factor RF, antistreptolysin O, C-reactive protein) cardiovascular function monitoring (detection of high-...

AI Technical Summary

Problems solved by technology

[0006] 1) The detection reagent R2 needs to be added manually. Since the reaction cup has a tapered opening at the upper end and a vertical narrow-diameter cavity at the lower end, when manually dropping the detection reagent, it is very easy to drop part of the detection reagent on the reaction cup due to the operator's operation error. On the inner wall of the cup, the amount of the detection reagent participating in the reaction is insufficient, thereby affecting the detection result;

[0007] 2) It takes a period of time for the reaction between the detection reagent R1 and the sample to be detected. When the instrument prompts the operator to add the detection reagent R2, because the operation proficiency of each operator or the speed of adding the detection reagent will vary, this will make the The reaction time between the detection reagent and the sample to be tested is different, resulting in differences between the test results; at the same time, this manual addition method increases the workload of the test personnel, and is prone to monitoring errors that affect the test results

[0008] 3) The amount of detection reagent R2 added is generally a few microliters, which requires a high level of skill for the operator. A little carelessness will result in insufficient amount of detection reagent added, which is prone to errors, thus affecting the accuracy of the measurement results

[0009] 4) The detection reagent R1 is pre-installed in the cuvette, long-term storage will cause changes in its composition, for example, volatilization or reaction with air will cause composition changes, etc., which will affect the detection results of specific proteins
