Abstract

The invention relates to a device and method for detecting blood leukocytes. Leukocytes play an important role in a human body. Total amount and differential counting of the leukocytes have certain significance in diagnosing various diseases. The conventional method for detecting the leukocytes always combines with two or more detection principles, combines with the techniques, such as, electrics, optics and cytochemistry, and is complex in the detection process. The invention provides the device and method for detecting blood leukocytes in a simple process, for achieving the purpose of analyzing the total amount of the leukocytes. A user can judge if the quantity and size of the leukocytes are abnormal in the manner of adopting laser light for scattering the blood diluted with sheath fluid, collecting the scattering light along the direction at 0 degree and analyzing and comparing the light shadow after scattering.

Description

technical field [0001] The invention relates to a blood leukocyte detection device and method, belonging to the field of medical inspection, and in particular to a device and method for analyzing the quantity and size of white blood cells in blood. Background technique [0002] Leukocytes are a very important type of cells in the blood. They play important roles in the human body, such as immune resistance to diseases, resistance to pathogen invasion, and phagocytosis. White blood cells are divided into neutrophils, lymphocytes, monocytes, eosinophils, and basophils. The total number and differential count of white blood cells have certain significance for the diagnosis of many diseases. [0003] In the existing white blood cell measurement methods, the sheath flow technology is often combined. After the blood is processed with the staining solution or the sheath fluid, the cells are pushed into the flow cytometry tank, and the electrical resistance of the blood is detected ...
