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 immunoassay system is completely arranged and configured according to the enzyme immunoassay process, which is large in size and cannot be used for single-use analysis. Reagent or double-dose biochemical index detection with various detection methods;

[0010] 4. The fully automatic biochemical and immune analyzer described in patent CN2847292Y needs to manually add the sample into the hole of the reaction strip in advance. The liquid adder is composed of a liquid storage box, a pressurizing device and a liquid level sensor. Although the structure is simple, However, there are many kinds of reagents involved in enzyme immunoassay. Reagents for qualitative detection include sample diluent, washing solution, enzyme conjugate, enzyme reaction substrate, chromogenic reagent, stop solution, positive control serum, negative control serum, critical control serum, etc. 9 kinds of reagents for quantitative determination, including diluent, washing solution, enzyme conjugate, enzyme reaction substrate, chromogenic reagent, stop solution, 5 levels of standard or calibrator, positive quality control substance, negative quality control substance, etc. 13 types, if the above-mentioned liquid adder is used, the reagent needs to be transferred from the universal reagent bottle to the liquid storage box in advance, the operation is complicated, and contamination and misplacement are prone to occur

The VITROS 5600 automatic biochemical and immune analyzer needs special reagents for detection, and only dry chemical analysis methods can be used for biochemical detection. At present, wet biochemical analysis methods and reagents are still dominant, making it difficult to popularize
