In order to solve the precise quantitation problem existing in the prior electrolyte analysis module, the invention provides an electrolyte analysis module with more precise quantitation, which is embedded in an automatic biochemical analysis system. The electrolyte analysis module comprises a sample feeding mechanism, an electrolyte measurement module, a display and main control unit, and a mechanical liquid channel system, wherein the sample feeding mechanism and the display and main control unit share mechanical hardware and circuits of the automatic analysis system; a liquid channel of the mechanical liquid channel system is driven by a peristaltic pump; and the liquid channels at both ends of the electrolyte measurement module are provided with a photovoltaic liquid detector respectively. The electrolyte analysis module has the advantages of solving the precise quantitation problem existing in the prior electrolyte analysis module, providing an electrolyte analysis module with more precise quantitation, making the structural improvement more simple and convenient, making the design of the electrolyte analysis module more intensive and greatly lowering production cost of the prior automatic biochemical analysis system. The invention provides an electrolyte analysis module and a method for self calibration of the pump volume of the peristaltic pump in the electrolyte analysis module.

Description

technical field [0001] The invention relates to electrolyte analysis technology in the field of biochemical detection, in particular to an electrolyte analysis module applied to a fully automatic biochemical analysis system and a method for self-calibrating the pump volume of a peristaltic pump. Background technique [0002] In the field of clinical chemistry testing, electrolyte analysis mainly refers to the detection of Na in body fluids. + , K + , Cl - and HCO 3 - Plasma activity was measured. When certain organs of the body develop disease or are affected by exogenous factors, it may cause or be accompanied by electrolyte metabolism disorders. If it is not detected and corrected in time, it may lead to physiological dysfunction of the whole body organ system, especially the cardiovascular system and nervous system. And substance metabolism disorders, which will be life-threatening in severe cases. Therefore, timely and accurate analysis of the activity of various i...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem of accurate quantification of the existing electrolyte analysis module, and provide a more accurate electrolyte analysis module based on a peristaltic pump and a self-calibration method for the pump volume of the peristaltic pump

[0007] The existing electrolyte analysis module can calculate the flow rate of the liquid in the flow path through the number of rotation steps of the peristaltic pump, and then perform quantitative analysis on the electrolyte. The flow rate of liquid pumped in step by step will change so that accurate quantitative measurement cannot be performed, and thus accurate measurement and analysis of electrolytes cannot be guaranteed
