Auto hematology analyzer four development stages faults

Auto hematology analyzer referred to as blood instrument, it has experienced four development stages, microscope age, cell count instrument era, leukocyte clustering and leucocyte classification era, these four stages have their shortcomings, specific content shown below:

Auto blood analyzer first stage: microscope
Counting parameters: the red blood cells, white blood cells, platelets, leukocyte five classification, hemoglobin
Lack of point:
1, counting parameters less: can't provide more information
2, human error: it is difficult to ensure consistent results
3, labor intensity: no suitable mass detection
Blood cell analyzer of the second stage: cell count apparatus
Counting parameters: the red blood cells, white blood cells, platelets, hemoglobin

Lack of point:
1, the analysis parameters of little: can only count red/white blood cells, and platelets and hemoglobin requires other medical equipment testing
2, the detection speed slow: every time can only detect a cell, pressure, dilution, filtering functions is still not perfect
3, open treatment: it is difficult to control, is only the prototype of a cell analyzer, the clinical no too big significance
Blood cell analyzer the third stage: white blood cells clustering

Three clustering fully automatic blood analyzer: in clustering on the basis of, and can be divided into semi-automatic, must fully automatic and fully automatic, with all kinds of advanced technology application, the blood cell detection by the original simple counting promoted to include a variety of parameters of cell analysis.
