PURPOSE:To easily judge a blood stream even when a speed is generated not within a set range by making a display surface circular, respectively coloring circular arc areas, which are divided by a straight line passing through the center of this circle into two, and providing a color scale for which the colors of the areas are changed corresponding to the speed of the blood stream. CONSTITUTION:Based on a measuring range, the display surface of the color scale is made circular. Red is set to (0 to + pi), out of the circle, namely to (0 to + Vmax) as the regular direction of the blood stream and blue is set to (0 to - pi), namely, to (0 to - Vmax) as the reverse direction of the blood stream. Those colors are set to be 'dark' near 0 and to be 'bright' gradually toward the +Vmax or -Vmax. By this setting, each time the speed of the blood stream is improved, the color is closed to be 'bright' and the speed can be judged corresponding to the color. While the blood stream of a reagent is measured, for example, when the speed of the blood stream in the regular direction is not within the range set to the color scale, namely, when the speed is displayed in the area of the reverse direction, the color scale is moved in a boundary line between the (0 to + Vmax) and (0 to - Vmax). Then, the speed range of the blood stream is enlarged and the speed is judged. |
