Abstract

The invention relates to the field of a medical cell analyzer, in particular to a signal effectiveness analysis method and device applied to a cell analyzer. The analysis method comprises the steps of acquiring particle/cell data by a signal acquisition channel, grouping the particle/cell data to obtain more than two groups of particle/cell segmented signals, and sorting the obtained signals; carrying out statistics on all segmented pulse parameters; calculating segmented credible coefficients and segmented variation trends according to all the segmented pulse parameters; and then, comparing the segmented credible coefficients and the segmented variation trends with preset threshold values to judge whether the data is abnormal or not. After the method and the device are adopted, the acquired overall data can be processed in a segmented way, so that the effectiveness of the acquired digital signals can be accurately analyzed; whether the data is abnormal or not can be judged on the premise of not prolonging the measurement time and not increasing the sample amount, so that the reliability of the measuring result can be improved.

Description

technical field [0001] The invention relates to the field of medical cell analyzers, in particular to a signal validity analysis method and device applied to cell analyzers . Background technique [0002] Hematology analyzer is one of the most widely used instruments in hospital clinical testing. It refers to the instrument that detects and analyzes the number and heterogeneity of blood cells in a certain volume. With the application of electronic technology, electronic computer technology, flow cytometry, laser technology and new fluorescent chemical substances in blood cell analyzers, the detection principle of blood cell analyzers has been continuously improved, and the measurement parameters have been continuously increased. The level is constantly improving, the degree of automation is getting higher and higher, and it is developing in the direction of fast, accurate and trace. But all of these products have a common technical feature that, no matter what measuremen...
