Hematology Analyzer

    Hematology analyzer, also known as blood cell analyzer, blood cell counter. This machine is widely used at all levels of hospital in China as well as around the world. It not only improves the accuracy of the experimental results, but also provides a number of experimental indexes, which play an important role in the diagnosis and differential diagnosis of the disease.    

    The hematology analyzer is a very wide range of hospital clinical laboratory instruments. The blood test blood means the common test of blood counted under the microscope, which includes red blood cells, hemoglobin, white blood cell count and its classification, platelet count, a total of 10 to projects. A patient's blood test is the most skilled, the most rapid at least 10 minutes. With the rapid development of science and technology, the automated hematology analyzer, blood cell analysis technology has changed from three sorts to five sorts since these years, and turned to the three-dimensional space from two-dimensional space, while the modern blood cell analyzers and five classification techniques use many advanced technology, such as the sheath flow technology, laser technology.

    In 1947, U.S. scientists Coulter (W.H.Coulter) invented the patented technology to count particles using a resistor. 1956 he successful applied this technology into blood cell count, the principle according to the non-conductive nature of the blood cells, blood cells suspended in the electrolyte solution to detect the resistance change caused by counting the holes, the blood count and volume determination, this method is called the resistance method or principle of Coulter. In 1962, the first blood count analyzer successfully developed in Shanghai. To the 1960s, the blood cell analyzer not only can count the blood cell, but also simultaneous determination of the HGB hemoglobin. In the 1970s, the platelet count instrument. In the 1980s, developed a classification of leukocytes (Category 3 and Category 5). In the 1990s, developed a blood cell count of red blood cells on the mesh analyzer, while five classification and the detection of immature cells are more mature and developing into blood cells analysis pipeline.
