Abstract

The invention belongs to the technical field of blood cell analysis, and particularly relates to a blood cell analysis chip, analysis meter and analysis method. The blood cell analysis chip disclosed by the invention comprises a white blood cell / hemoglobin analysis chip and a red blood cell / blood platelet analysis chip; the white blood cell / hemoglobin analysis chip performs white blood cell classification by adopting the sheath flow technology and the multi-angle laser polarized light scattering technology, and detects the concentration of hemoglobin by adopting the light absorption method; the red blood cell / blood platelet analysis chip counts the red blood cells and blood platelets respectively by adopting the electrical impedance technology and the floating threshold technology. According to the invention, the blood cell analysis chip is utilized to realize classification of blood cells, has the advantages that the structure is simple, the size is small, the cost is low, the operation is convenient, the easy maintenance and transportation are realized, the chip can be discarded after being used, and the like, satisfies the development requirements of miniaturization, integration and portability of an analysis instrument, and is particularly suitable for field detection, emergency analysis, household application and use of primary care departments.

Description

technical field [0001] The invention belongs to the technical field of blood cell analysis, and in particular relates to a blood cell analysis chip, an analyzer and an analysis method. Background technique [0002] The information obtained from blood cell analysis can be helpful for the diagnosis and differential diagnosis of diseases related to the blood system, for analyzing the condition, observing the curative effect, and judging the prognosis, providing evidence for disease prevention, guiding clinical medication and carrying out clinical medical research, so blood cells Test (that is, blood routine) has become the first of the three routine tests (blood routine, urine routine, and stool routine) in clinical testing, and its clinical application is also the most extensive. Since Mr. Coulter invented the electrical impedance blood cell counter in 1953, various automatic blood cell analyzers have come out one after another, and blood cell analysis technology has developed...
