The TRL-type extracorporeal circulation perfusion thermo-chemotherapy treatment system produced by Harbin Yuhang is the first new type of medical equipment in China that applies thermophysical technology of body cavity to prevent and control implantation metastasis in body cavity and treat cancerous fluid. This equipment utilizes puncture technology or postoperative indwelling catheter technology to automatically heat up the thermal perfusion solution or cancerous fluid in the treatment machine, and then establishes the circulation through the closed circulatory pipeline. Under the computerized dynamic monitoring and feedback regulation, the perfusion solution maintains a constant temperature during the treatment time, which effectively kills and maims the tumor cells. The whole mechanism can stop the recurrence of cancerous fluid. It has successfully solved the problems of non-constant temperature of body cavity perfusion, non-ideal thermal homogenization of body cavity temperature, complicated operation, etc., and avoided the series of sequelae such as encapsulation, adhesion, intestinal obstruction, etc., which are often associated with the traditional therapies.
