The invention relates to the technical field of biochemical analyzers, and in particular relates to a method for improving reading accuracy of a biochemical analyzer. The method comprises the steps that S1 the position of a reaction disc is initialized; S2 an upper computer sends the number N of pulses required to move by a motor, and records the complete number of pulses of at least one outer tooth of the reaction disc and the potential change of an outer tooth optocoupler; S3 the pulse number Nx and the pulse number Ny corresponding to any outer tooth are analyzed according to the data recorded in the S2, and the deviation pulse number N1 of two adjacent outer teeth is obtained; S4 the upper computer commands the reaction disc to return to the initialization position again, movement of the offset pulse number N1 is completed, then the reaction disc continues to rotate, pulse number values A1, A2,..., Am corresponding to the stable value of each cuvette are analyzed, and the pulse number values of the corresponding output signals of the outer tooth optocoupler are recorded as M1, M2,..., Mm when the output signals of the outer tooth optocoupler are changed from high to low; and S5 reading is carried out according to the set pulse number Am-Mm corresponding to each cuvette so as to improve the reading accuracy.
Description
technical field [0001] The invention relates to the technical field of biochemical analyzers, and in particular to a method for improving the reading accuracy of biochemical analyzers. Background technique [0002] Biochemical analyzer is one of the important instruments commonly used in clinical diagnosis. It measures various biochemical indicators through the analysis of blood and other body fluids, such as hemoglobin, cholesterol, muscle liver, transaminase, glucose, inorganic phosphorus, etc. Most biochemical analysis The instrument works based on the principle of photoelectric colorimetry, mainly through the motor to drive the reaction disc to rotate, with the help of its external teeth and the use of photocouplers, the reading module can read the samples in the color cup to obtain the data and upload it to the host In principle, the reading module needs to read the central position of the cuvette, because the reading value at the central position of the cuvette is the ...
