The invention relates to the technical field of biochemical analyzers, and in particular to a method for improving the reading accuracy of biochemical analyzers. The method steps are: S1: initializing the position of the reaction disk; Record the complete pulse number of at least one outer tooth on the disk and the potential change of the outer tooth optocoupler; S3: analyze the pulse number Nx and pulse number Ny corresponding to any of the outer teeth according to the data recorded in S2, and obtain the two adjacent The number of deviation pulses of the outer teeth is N1; S4: The host computer commands the reaction disc to return to the initialization position again, and completes the number of deviation pulses N 1 Then the reaction disk continues to rotate, and the pulse number value A corresponding to the stable value of each cuvette is analyzed 1 ,A 2 ,...A m , record the value of the pulse number when the output signal of the corresponding external gear optocoupler changes from high to low as M 1 ,M 2 ,...M m ; S5: according to the set pulse number A corresponding to each cuvette m -M m Take a reading to improve the accuracy of the reading.
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 ...
