Fully automatic biochemical immune analyzer

Abstract

The invention provides a fully automatic biochemical immune analyzer which comprises a rack, and a sample support, a reagent shelf assembly, an injection assembly, a washer, a reaction plate assembly, a washing assembly, an optical measuring assembly, a water channel and gas channel system and a circuit control system which are arranged on the rack. The fully automatic biochemical immune analyzeris mainly used for fully automatic quantitative measurement or qualitative detection of immune and biochemical indexes of human blood and other body fluid, concentration of therapeutic drugs and general ingredients, harmful additives, harmful and toxic elements, residues of pesticides and veterinary drugs, microbial toxins and the like in the food safety field.

Description

technical field [0001] The application of the present invention relates to a fully automatic biochemical immune analyzer, which can perform automatic quantitative or qualitative detection of biochemical and immune indicators, and belongs to the technical field of biological monitoring equipment. Background technique [0002] The automatic biochemical analyzer is mainly used for biochemical and chemical components in clinical blood and other body fluid samples such as hemoglobin, cholesterol, triglycerides, albumin, C-reactive protein, glutamic acid aminotransferase, glucose, potassium, sodium, Quantitative determination of calcium, etc., is one of the most commonly used testing instruments for clinical analysis. [0003] At present, discrete biochemical analyzers are commonly used in clinical medical institutions. The instrument consists of a sample tray, a reagent rack, a sample sampling device, a reagent sampling device, a reaction tray, a colorimetric device, a reaction c...

Problems solved by technology

[0007] 1. The reagent racks of various manufacturers of discrete biochemical analyzers usually have different capacities and appearance designs. In order to facilitate operation, the reagents on the machine are required to have different specifications and appearance designs, which increases the cost and is not conducive to clinical laboratory expansion or Replacement of testing items; the production process of dry reagent strips used in dry biochemical analyzers is much more complicated than that of traditional liquid reagents, and the price is more expensive, especially the price of quality control products, and is not suitable for mass testing; discrete biochemical analyzers and None of the dry biochemical analyzers can implement the enzyme-linked immunoassay analysis process. If the laboratory needs to detect biochemical and immune indicators on the same specimen, it needs to conduct experiments on a separate enzyme-linked immunoassay equipment;

[0008] 2. In laboratories using plate washer and microplate reader, only the automation of plate washing and absorbance reading in the process of enzyme immunoassay is realized, and other detection processes such as adding samples, adding reagents, incubation, shaking and data analysis are all It needs to be done manually with the help of other independent experimental tools or equipment, the operation is complicated, it is easy to cause reagent pollution and waste, and it is prone to errors;

[0009] 3. The automatic enzyme-linked immunoassay system is expensive, and requires the use of special reagents, the detection cost is high, and it is not easy to popularize; the assembly line enzyme-linked immunoass
