Automatic analytic device and working method thereof

Abstract

The invention discloses an automatic analytic device and a working method thereof. The automatic analytic device comprises a reaction tray, a reagent injection mechanism and a sample injection mechanism, wherein the reaction tray is used for bearing a reaction beaker and driving the reaction beaker to rotate or stop at the preset position; the reagent injection mechanism is positioned near the rotating track of the reaction tray and used for injecting a reagent into the reaction beaker; the sample injection mechanism is positioned near the rotating track of the reaction tray and used for injecting a sample into the reaction beaker; the reagent injection mechanism is provided with a reagent needle, and the sample injection mechanism is provided with a reagent needle; in each working period, the reaction tray is respectively started and stopped at least twice; and the reagent needle and the sample needle are used for respectively adding the reagent and the sample in different stop periods. The invention can realize the constant speed testing on one, two or more reagent projects at lower cost, and avoids the restriction on the relative position relationship between the reagent needle and the sample needle, thereby being beneficial to the structural layout design of the complete machine.

Description

【Technical field】 [0001] The present invention relates to an automatic analysis device and its working method for analyzing the reaction solution respectively injected into the reaction container sample and the reagent. 【Background technique】 [0002] Automatic biochemical analyzer is a kind of biochemical analysis product that is widely used at present. It is used in clinical laboratories to detect various biochemical indicators of blood, urine or other body fluids. Its characteristic is to imitate manual operation to complete a series of processes such as adding reagents, adding samples, mixing, heat preservation reaction, absorbance detection and result calculation in biochemical analysis. The 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 oper...

AI Technical Summary

Problems solved by technology

[0004] If the structure design of the analyzer is unreasonable, it may cause interference between the sample needle for adding the sample and the reagent needle for adding the reagent. In addition, if the timing design of adding the reagent and adding the sample is unreasonable, there may be a strong gap between the two needles. The relative position restriction of the system affects the optimization of the structural layout, for example, it leads to the increase of the whole machine components, the large structure, and the cost increase, etc.
