When the heat preservation catheter leaks, the second leakage detection point 133 and the first leakage detection point 132 can quickly pass through the leaked heat preservation liquid and the body fluid of the patient to realize capacitance change or conduction, so that leakage is prompted.

Alternatively, the head end of the inner tube 122 is provided with a communication through hole for communicating the inner flow channel and the outer flow channel. So that the heat preservation liquid can flow through the inner layer runner and the outer layer runner in sequence.

After the fault logic processing unit receives the judging information, the corresponding processing information can be output to an external executing element according to the fault logic processing unit, and the external executing element can comprise a liquid storage pressurizing unit, a liquid driving unit and a heating unit which are arranged on the heat preservation conduit, and the liquid pressure, the flow rate and the temperature are respectively and correspondingly adjusted by controlling the liquid.
