Reaction cup chain and biochemistry analyzer using the same

Abstract

The invention discloses a reaction cup chain, which comprises: at least two reaction cups aligned on a cup chain main body, and a light blocking part, wherein the light blocking part is positioned on an outer side of at least one reaction cup, extends outwardly along an operation direction or a reverse direction of the reaction cup during detection, and is used for reducing light intensity of detection light incident to a photoelectric detection system. According to the present invention, a light blocking part is arranged on a detection light path during detection so as to reduce light intensity of the light path positioned between reaction cups or a reaction cup chain during a detection process, such that a change amplitude of a light intensity signal received by a receiving end becomes small, a problem of a error result caused by insufficient signal establishing time during a test is solved, and a high signal-to-noise ratio of the system is ensured.

Description

technical field [0001] The invention relates to a reaction cup chain, which can be applied to various analyzers. Background technique [0002] The cuvette chain in the prior art is usually an arc-shaped cup chain composed of more than three open cuvettes. The cup chain is made of transparent material by injection molding, the whole body is transparent, and the gap between the cups can transmit light. In the current automatic biochemical analyzer, the cuvettes containing the reaction solution pass through the optical detection system in turn, and the optical detection system judges the content of the sample by measuring the ratio of the incident light intensity and the outgoing light intensity of the sample corresponding to different wavelengths. material composition. During the test, the space between the cuvettes and the cuvettes pass through the photoelectric detection system in turn. Generally, the space between the cuvettes is not blocked or simply blocked, and the tra...

Problems solved by technology

[0005] The beneficial effects of the present invention are: by setting the light blocking part on the detection light path during detection, the light intensity when the light path is located between the cuvettes or between the cuvette chains during the detection process can be weakened, so that the light received by the receiving end The change range of the strong signal becomes smaller, which solves the problem of incorrect results caused by insufficient signal establishment time in the test, and at the same time ensures a high S / N ratio of the system
