Method for drawing infusion dropping speed and infusion time query graph and query graph

The invention relates to a method for drawing an infusion dropping speed and infusion time query graph and the query graph. The method for drawing the infusion dropping speed and infusion time query graph comprises the following steps of: defining three variables of the infusion dropping speed, the infusion time and infusion quantity as: the infusion dropping speed is equal to the infusion quantity*20/the infusion time, wherein under the condition of determining the infusion quantity, an inverse proportional function relationship exists between the infusion dropping speed and the infusion time; in a rectangular coordinate system, defining the horizontal coordinate as the infusion time and longitudinal coordinate as the infusion dropping speed; and drawing the curve graph of the inverse proportional function of the infusion dropping speed and the infusion time according to the formula. The invention also provides the query graph drawn by the method. By adoption of the tool, the infusion dropping speed or the i
