Automatic biochemical analyzer

Abstract

An automatic biochemical analyzer, comprises a reaction wheel comprising an inner ring and an outer ring, wherein the reaction wheel is equally divided into multiple cuvette positions along a circumferential direction; the inner ring and the outer ring, respectively, each have a photoelectric detection position, a sample injecting position, a reagent injecting position, a sample stirring position, a reagent stirring position, and a cuvette cleaning position; the photoelectric detection position of the inner ring and the photoelectric detection position of the outer ring have a cuvette position interval of N along a counterclockwise or clockwise direction; and the sample injecting positions, the reagent injecting positions, the sample stirring positions, and the reagent stirring positions of the inner ring and the outer ring, respectively, have a cuvette position interval of M along the same direction, M and N being natural numbers, and the difference between M and N being 0 or 1.

Description

technical field [0001] The invention relates to a fully automatic biochemical analyzer. Background technique [0002] In the automatic biochemical analysis instrument, in order to automatically complete a series of test processes such as adding samples, adding reagents, stirring the solution, collecting reaction data, and automatically cleaning the reaction vessel, it is necessary to configure sample dispensing modules and reagents around the circumference of the reaction disk. Dispensing module, stirring and mixing module, photoelectric detection module and reaction cup automatic cleaning module, etc. Among them, the relative positions of the photoelectric detection position and sample dispensing position, reagent dispensing position, sample stirring position, reagent stirring position, and cuvette automatic cleaning position on the reaction plate directly affect the testing process of each test. [0003] In high-speed automatic biochemical analysis instruments, in order t...

AI Technical Summary

Problems solved by technology

Adopting the existing technical solution will result in the waste of at least four cup positions, that is, under the premise of meeting the requirements of the test process, it is necessary to configure at least eight more reaction cups, resulting in a waste of the number of reaction cups

The number of reaction cups will directly affect the cost of the instrument, and will also affect the size of the reaction plate. More reaction cups mean a larger diameter of the reaction plate, and a larger reaction plate will also increase the height of the reaction plate. Accurate drive control brings greater challenges, of course, it will also lead to an increase in the overall size of the machine
