Abstract: PURPOSE:To provide a hyperthermia device to prevent drop of the termo-therapy effect at a low cost by furnishing a driving means to drive a flow path changeover means and a pump device so that the pure water in a tank returns to a pure collecting means. CONSTITUTION:An electroconductivity measuring device 9 furnished on a flowing water return path for cooled pure water measures at all times the conductivity of the cooled pure water being fed back in a boras 8. When the conductivity exceeds a set value, an alarm output device 10 emits signals to drive No.2 pump 11 and a three-way solenoid valve 2. This No.2 pump 11 starts upon receiving an appropriate signal and sucks the used pure water in a pure water storing 4. At the same time, the three-way solenoid valve 2 switches the flow path so that the used pure water circulates from the outlet of No.2 pump 11 to the influx hole of a pure water making device 3. The used pure water sucked circulates through the flow path to be sent into this pure water making device 3, and pure water is collected from the used water and sent to the tank 4. Thus the used water in the tank 4 can be converted into pure water having high purity.
