Full-automatic biochemical analysis method

Abstract

The invention discloses a full-automatic biochemical analysis method. The method comprises the following steps: (1) preparing; (2) sampling, sample adding and stirring: an XYZ triaxial movement system is driven by a controlling circuit module to drive a reagent-sample adding and stirring system to transfer samples from a sample cabin to a reaction cup in a reaction disc and transfer reagents from a reagent cabin to the reaction cup in the reaction disc; when the reagents and samples are transferred, liquid in the reaction cup is stirred through the reagent-sample adding and stirring system; the specific liquid volume of sampling and sample adding is controlled by a plunger pump; (3) biochemical reaction and detecting; (4) cleaning. According to the invention, procedures such as sampling, sample adding, stirring, analyzing and detecting, and cleaning are integrated, so that the degree of automation is high, the operation is convenient, the relevant equipment cost is low, the detecting efficiency is high, and the popularization and implementation are easy.

Description

technical field [0001] The invention relates to a fully automatic biochemical analysis method. Background technique [0002] At present, as one of the important instruments often used in clinical testing, automatic biochemical analysis instruments have been widely used in various large and medium-sized hospitals, providing essential information for clinical diagnosis, treatment, prognosis and health status of diseases. It has become an indispensable standard equipment for large and medium-sized hospitals, but the existing automatic biochemical analyzers also have disadvantages such as large volume, complex structure, high price, and inconvenient maintenance. A fully automatic biochemical analyzer often costs hundreds of thousands of dollars After the purchase, small hospitals, township health centers and social health centers are usually unable to purchase, which limits the comprehensive popularization of automatic biochemical analyzers, and brings difficulties to the diagno...

Problems solved by technology

[0002] At present, as one of the important instruments often used in clinical testing, automatic biochemical analysis instruments have been widely used in various large and medium-sized hospitals, providing essential information for clinical diagnosis, treatment, prognosis and health status of diseases. It has become an indispensable standard equipment for large and medium-sized hospitals, but the existing automatic biochemical analyzers also have disadvantages such as large volume, complex structure, high price, and inconvenient maintenance. A fully automatic biochemical analyzer often costs hundreds of thousands of dollars After the purchase, small hospitals, township health centers and social health centers are usually unable to purchase, which limits the comprehensive popularization of automatic biochemical analyzers, and brings difficulties to the diagnosis and treatment of patients for the majority of grassroots medical workers;

[0003] The structure of existing biochemical analyzers is extremely complex, for example, the sample addition system and the stirring system are configured separately, which brings great obstacles to the size reduction of the analyzer; therefore, it is necessary to use a unique design to integrate the stirring and sample addition systems together;

[0004] In addition, the structure of the cleaning system is complex and the cost is high. Therefore, it is necessary to design a new type of low-cost and easy-to-implement cleaning system to complete the cleaning process;

[0005] Moreover, the existing biochemical analyzers are not highly automated and require operators to add samples manually, which is prone to errors and affects test accuracy and efficiency.
