Improved automatic biochemical analyzer and usage method thereof

Abstract

The invention provides an improved automatic biochemical analyzer and a usage method thereof. A first reagent sampling arm, a sample mixing device, a washing device, a photoelectric detection device, a sample sampling arm, a reagent mixing device and a second reagent sampling arm are distributed outside the circumferences of reaction discs of reaction cups with the number of 2n of the analyzer in a counter-clockwise direction; a reagent disc is located between the two reagent sampling arms, and samples, a reagent sampling position and a mixing position are arranged to a G point from an A point according to the speed of the analyzer and reagent incubating time. The method comprises the following steps: the reaction cups are in stop-rotation alternate periodic operation, every operation cycle has two sampling cycles, and the reaction discs rotate cups with the number of m in every sampling cycle, stop, rotate the cups with the number of n+1-m again, and stop again; sampling and mixing is performed when the reaction discs stop; the reaction cups orderly stop at A, E, B, G, F, D and C, a first reagent is added, the samples are added, the samples are mixed, a second reagent is added, the samples are mixed, data is collected, submitted and detected to calculate results after reaching incubating time, and reaction cups are washed. The improved automatic biochemical analyzer only needs one reagent disc and one driving device to finish the addition of the two reagents, and the incubating time can be regulated.

Description

technical field [0001] The invention relates to the technical field of biochemical analysis, in particular to an improved automatic biochemical analyzer and a usage method thereof. Background technique [0002] When performing biochemical analysis, it is necessary to inject the sample to be tested (human or animal body fluids, such as blood, urine, etc.) and reagents into the cuvette, mix well, and perform a chemical reaction (ie incubation) for a certain period of time. It usually takes a few minutes to more than ten minutes for a biochemical analysis project to complete the above steps, and a sample to be tested generally needs to be tested for more than a dozen biochemical indicators. An automatic biochemical analyzer was developed for this purpose. [0003] Automatic biochemical analyzer is an indispensable testing equipment for biochemical laboratories and hospital laboratories. Existing automatic biochemical analyzers generally include reagent trays, sample trays and...

Problems solved by technology

[0004] In the existing automatic biochemical analyzer with a test speed of more than 400Test / h, in order to achieve a high test speed, the layout of the instrument is generally fixed, and the incubation time cannot be adjusted

and requires two reagent discs and their drives
