Embodiment Construction

[0022] see figure 1 , the automatic biochemical analysis device of the present invention comprises a reaction disk 1, a reagent disk 2, a sample disk 3, a first reagent needle assembly 4, a second reagent needle assembly 5, a sample needle assembly 6, a reagent stirring rod assembly 7, a sample stirring rod assembly 8. A cuvette cleaning mechanism 9 and an optical detection device 10 .

[0023] The reaction disk 1 is arranged in the middle of the working table of the instrument, and ninety reaction cups 11 are arranged at equal intervals along the circumference of the reaction disk. The reaction cups 11 are designed permanently or semi-permanently. Realize the rotation positioning of the cuvette. The reaction tray 1 is provided with a constant temperature device to ensure that the reaction solution in the reaction cup is maintained at 37°C.

[0024] The reagent tray 2 is arranged at the front left side of the instrument worktable, and forty reagent positions are arranged at ...

Abstract

The invention discloses a full automatic biochemical analysis method. A serial of reaction vessels move to make at least one reaction vessel passing through an optical measuring channel in the work period of holding prior sample sampling operation on a serial of reaction vessels arranging in a ring shape to the next sample sampling operation, moreover, within the working period, making a serial of reaction vessels to stop adding sample in midway. A first reagent adding position and a sample adding position in spacing distribution orderly are arranged in the moving route journey of a serial of reaction vessels, when a serial of reaction vessels stop for adding the sample, adding the sample to the reaction vessels in the sample adding position; when stopping in the midway, adding the first reagent to the reaction vessel positioned in the first reagent adding position, moreover in relation to each reaction vessel, the working period of adding the sample lags the working period of adding the first reagent. The method can reduce the cross pollution of reagent and improve the working speed.

Description

technical field [0001] The present invention relates to a method and a device for analyzing multiple items by biochemical analysis. Background technique [0002] Discrete automatic biochemical analyzer is the most widely used biochemical analysis product at present. It is used in clinical laboratories to detect various biochemical indicators of blood, urine or other body fluids. Its characteristics are: imitating manual operation to complete biochemical A series of processes in the analysis, such as adding reagents, adding samples, mixing, incubating reaction, absorbance detection and result calculation. The biochemical analysis instrument is mainly composed of a reaction tray including a constant temperature system, a sample tray or a sample transfer rack, a reagent tray, a sample dispensing mechanism, a reagent dispensing mechanism, a stirring mechanism, a reaction cup cleaning device and a user operating system. [0003] The US patent No. US 5,773,662 discloses a biochem...
