(Erythrocyte Image System) is a specialized instrument intended to make image analysis of functional statues of human erythrocytes by the combination of German Leica high-resolution optical components and computer analysis system. Taking 1 μl fingertip blood as the observation sample, the system mainly uses ultramicroscope as the main observation means to clearly observe the functional statuses of erythrocytes of patients, such as aggregation status, deformability and activity. By comparison with normal erythrocytes, user unit could discover functional disorders of erythrocytes in early stage and make intervention therapy, so as to prevent the formation of thrombotic diseases such as acute myocardial infarction, cerebral stroke, coronary heart disease and pulmonary embolism and determine the direction and target of health management. Examination results can be obtained immediately, very safe and convenient!
