Introduction of
hematology analyzer
Hematology analyzer machine is also called hematology analyzer, blood analyzer, blood cell analyzer, blood cell counter. Hematology analyzer plays an important role in the diagnosis and differential diagnosis of the disease. And it has wide range of instruments in the hospital clinical laboratory applications, blood tests the blood test, the first manual counting under the microscope, which include red blood cells, hemoglobin, white blood cell count, and its classification, platelet count, etc., a total of 10 to the project. Do a patient's blood test is the most skilled, the most rapid but also some 10 minutes.
With the rapid development of science and technology, the automated hematology analyzer, blood cell analysis technology from a few years ago, three classification to five classification, then turned to the three-dimensional space from a two-dimensional space, the five categories of of modern blood cell analyzer many uses state-of-the-art technology, such as a sheath flow technology, laser technology.
A brief history of the hematology analyzer
1947 the American scientist Kurt (WHCoulter) invented the patented technology of particle counting using a resistor. 1956, he will apply this technique to hemocytometer successful, its principle is based on the non-conductive nature of the blood cells, and detect the change in resistance to the electrolyte solution in the suspension of blood cells as caused by counting orifice hemocytometer and volume determination, this method is called resistance method or Kurt principle. In 1962, China's first hemocytometer successfully developed in Shanghai. The 1960s, not the blood cell analyzer, can be blood count can also simultaneous determination of the HGB hemoglobin. 1970s, the advent of platelet count instrument. In the 1980s, the development of the WBC (3 classification and classification). 1990s, developed the reticulocyte count, blood cell analyzer 5 Classification and naive cells detected more mature, and develop into blood cells analysis pipeline.
Principle and Technology
Full digital processing technology of cell signal, Mature fluid path design, to ensure the reliability of the measurement results of the detection operation, advanced floating landmark algorithm, combined with a sound abnormal blood sample expert identification system, the abnormal samples made independent hemoglobin measurement system Filter Step unique volume metering tube direct quantitative techniques to eliminate the source of interference, to improve the accuracy of u particle wizard Technology: cell particles to linear motion, a real pulse to ensure the WBC, RBC the PLT count accurately u bi-directional stereo after cyclone technology: avoid fluid PLT count the three classification u dual-channel interference u leukocyte, 60 tests / hour u new high-precision small amounts of blood processing technology u electrical impedance, cyanide methemoglobin law and cyanide the SFT method u big screen 8.4 inch TFT touch screen.
