PROBLEM TO BE SOLVED: To provide a defect detection method for an administration device of a radioactive drug solution, capable of detecting a liquid feed defective state in an administration line with a simple configuration, and to provide the administration device of a radioactive drug solution.SOLUTION: In the administration device 1 of a radioactive drug solution, when a detection value detected by a load cell 33 is a threshold or smaller, the liquid feed defective state is detected by a control means 34. Thus, the possibility of occurrence of leakage or backflow or the like of liquid is detected. By utilizing the load cell 33 provided in order to detect an overload state for the detection of the liquid feed defective state such as the leakage or the backflow, the need of separately providing a measurement device or the like is eliminated and the liquid feed defective state is detected with a simple configuration. |
