PURPOSE: Provided is a rate and remainings indicator of Ringer's solution supplier for endoscopy which can quantitatively and qualitatively show the flow rate and remainings of the solution so that an operator or assistant can easily note the supplying status of the solution. CONSTITUTION: The rate indicator visualizes the flow rate and remainings of Ringer's solution by measuring the total weight of the Ringer's solution bag at intervals(0.5 or 1 sec) upon supplying the Ringer's solution. This rate indicator is located so that an operator or assistant can readily note the supplying status of the Ringer's solution. In the conventional operation or treatment while supplying Ringer's solution, the operator or assistant can not note the flow rate or supply status of the Ringer's solution. Since the conventional system using a forced circulation pump is bulky, the indicator is located at a down position where the operator or assistant cannot watch during their operation.
