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

Abstract

The invention discloses a dry blood cell analytical method. The technical principle of the method lies in that a specially-made centrifugal capillary tube is detected by a red light source and a blue light source, and an image is obtained through collection and analyzed, so that all the index parameters of complete blood cell count are obtained; during the analysis, the capillary tube is sequentially irradiated through the light sources of two colors, imaging for the capillary tube is carried out by a camera lens; images are collected by a colored thread CCD image sensor; the complete blood cell count subjected to data processing is displayed on a display screen and supports printout. The method consumes short time, is efficient, and can be used for quick and accurate whole blood cell analysis.

Description

technical field [0001] The invention relates to a medical field, in particular to a dry blood cell analysis method. 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 widely used in major hospitals and laboratories...
