Master control data processing system of dry type blood cell analyzing apparatus

Abstract

The invention discloses a master control data processing system of a dry type blood cell analyzing apparatus. The master control data processing system comprises a photoelectric sensor 6, a printer 1, a liquid crystal displayer 3 and a master control module 10. Through using the master control data processing system, functions of collecting data, processing images, driving the liquid crystal displayer and the like can be realized; a complete blood cell counting result is obtained after performing data processing on the collected image, displayed on a display screen, printed and output. The master control data processing system disclosed by the invention is equipped with a DSP (Digital Signal Processor) chip which is especially used for digital signal processing and is used for the image processing, so that the system operation speed is further increased, the time spent on analyzing is fully saved, and the detection efficiency is improved.

Description

technical field [0001] The invention relates to a medical device, in particular to a main control data processing system of a dry blood cell analysis device. Background technique [0002] Whole blood analysis is an important link for doctors to diagnose and analyze patients' conditions, and directly guides the development of follow-up medical behaviors. Hematology analyzers are instruments that specifically analyze whole blood. Various types of blood cell analyzers currently used clinically are mainly based on two types of methods: wet analysis technology and dry analysis technology. The former is based on the differences in physical and biochemical properties of different types of blood cells, based on flow cytometry in different flow paths and light paths, cell staining, light scattering, electrical impedance and other methods are used to distinguish and count cell types. The analytical instrument based on this method has mature counting and accurate results, and is widel...

AI Technical Summary

Problems solved by technology

Currently, analytical instruments based on dry technology on the market mainly use progressive scanning with photodiode imaging, or segmental scanning with monochrome linear array CCD for signal acquisition. The additional mechanical drive devices, filters and switching devices are Bottleneck in Seismic Performance Improvement

At the same time, the mechanically driven scanning greatly prolongs the detection and analysis time, fully exposing the defect of its low work efficiency when analyzing a large number of blood samples
