The present invention is directed to a flow controller of Ringer's solution for the medical use. The conventional type of controller having a shape of guide rail (2a) wherein the pressure control of the supply tube (7) is improved to achieve a reasonable injection depend on the clinical condition of a patient. In order to supply the solution according to the exhausting time or the scheduling amount of the solution based on the empirical data, the protruding edges on the axis (5) of roller (4) are combined into the stopper's holes (3) which are apertured along grooves (2) of the controller's frame (1) whereby the slide or roller (4) plugged into the holes (3) press or depress the resilient supply tube (7) for the control of flow rate. The flow of Ringer's solution through the supply tube (7) thus can be controlled by moving the roller (4) or slider to the indicating scale (6) corresponding to the flow rate, and consequently the injection of Ringer's solution can be safely performed without loss or surplus. |
