Abstract

The invention discloses an alkaline reagent filling fluid circuit system and a filling fluid circuit control method thereof. The system comprises a buffer, a first control valve connected with the buffer through a first pipeline, a first storage pot connected with the first control valve through a second pipeline, a second control valve connected with the first control valve through a third pipeline, an injection pump connected with the second control valve through a fourth pipeline, a third control valve connected with the injection pump through a fifth pipeline, a gear pump connected with the third control valve, and a fluid circuit system control unit connected with the first control valve, the second control valve and the third control valve. The system is used for improving the stability of a measurement value obtained through a fully-automatic chemiluminescence immunity analyzer, and safety performance is improved.

Description

technical field [0001] The present invention relates to the technical field of a liquid path system for filling alkaline reagents, in particular to an alkaline reagent filling liquid path system and a liquid path control method for enhancing the stability of a fully automatic chemiluminescence immune analyzer measurement value . Background technique [0002] The automatic chemiluminescent immunoassay system is an instrument that can perform immunological quantitative analysis on patient's body fluid samples, and can test anemia, cardiovascular disease, congenital diseases, sex hormones, infectious diseases, metabolic functions, tumor markers, and therapeutic drugs Monitor and syndromes of thyroid and other diseases. [0003] Chemiluminescence means that during a chemical reaction, the luminescent substrate absorbs the chemical energy generated during the reaction, causing the electrons in the product molecules of the reaction or the intermediate state molecules of the react...

Problems solved by technology

[0005] In the prior art, the photons are released in an instant, the time is extremely short, and the sample volume participating in the reaction is small, so the alkaline reagent injected last before emitting light affects the test result to a large extent, that is, the relative light unit, while the test It shows that the stability of the alkaline reagent flow rate is the key to obtaining stable test results, but small changes in the plunger pump, valve assembly and even pipelines during the filling of alkaline reagents will affect the stability of the test results. The anti-interference capability of the injection system is poor, which leads to the increase of the difficulty of controlling the filling of alkaline reagents, and the uniformity of the alkaline components in the alkaline reagents also affects the stability of the test results to a certain extent, so the present invention aims to Adding a set of alkaline reagents to the liquid system increases the stability of the alkaline reagents, improves the anti-interference ability of the liquid system itself, enhances the stability of the measured value, and reduces the difficulty of controlling the alkaline reagents.
