し、薬剤の配送を直ちに停止するようにしている。As described above, the medicine is fed from the tank 7 to the receiving facility 9, and at the same time, the inert gas is delivered from the inlet pipe 4 to the delivery pipes 1, 1 ', 1 "and the protective pipe 3 in parallel with this. This inert gas is continuously monitored by the sensor 10 through the discharge pipe 5 through the gap formed by the sensor 10, and the change in the component, that is, the detection of even a small amount of the drug component delivered in the delivery pipe in the gas is detected. If it is given, it means that there is a location where the medicine leaks in the delivery pipe between the joints 2 and 2 ′.
As a result, repair work can be performed immediately, and the occurrence of accidents can be prevented. Moreover, since the gas used here is an inert gas, it does not react with the drug leaked from the delivery pipe and is safe. The output detected by the above-mentioned sensor is sent to another component analysis device, and the components are instantaneously and accurately analyzed, and when an abnormality is detected, an alarm is issued and the delivery of the drug is immediately stopped. .

よる事故発生を一層確実に防止することができる。As described above, according to the present invention, the leakage of the drug is always detected from the change in the component of the inert gas. Therefore, if any amount is detected, an alarm is immediately issued and at the same time the drug transfer is stopped. Therefore, it is possible to more reliably prevent the occurrence of an accident due to the leakage of the medicine.
