Extracorporeal Circulatory Perfusion Thermo-Chemotherapy System is a new type of medical equipment that applies body cavity thermophysical technology to prevent and treat body cavity implantation metastasis and cancerous fluid. By using puncture technology or postoperative indwelling catheter technology, the system automatically heats up the perfusion solution or cancerous fluid in the treatment machine and establishes the circulation through the closed circulatory pipeline. Under the dynamic monitoring and feedback control by computer, the perfusion solution maintains a constant temperature during the treatment time, which can effectively kill 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, unsatisfactory thermal homogenization of body cavity temperature, complicated operation, etc., and avoided the series of sequelae such as wrapping, adhesion, intestinal obstruction, etc., which are often associated with traditional therapies. Scope of clinical application 1, pleural effusion, abdominal effusion, pericardial effusion caused by malignant tumors; 2, thermal treatment during and after surgery for gastric cancer, intestinal cancer, pancreatic cancer, ovarian cancer, uterine cancer; 3, prevention and treatment of diffuse diffuse metastasis of the abdominal cavity; 4, comprehensive treatment for malignant pleural mesothelioma; 5, anti-adhesion treatment for tuberculous pleurisy, peritonitis, pericarditis; 6, suppurative peritonitis, pus thoracic Treatment principle: According to the tumor cells and the normal human body, the tumor can be treated by the treatment. Therapeutic principle According to the difference in temperature sensitivity between tumor cells and normal cells of human body and their biological characteristics such as water content and blood flow, it adopts the principle of tumor thermotherapy, using the inductive non-contact heating device of extracorporeal circulation perfusion thermochemotherapy system to heat the therapeutic liquid to the therapeutic temperature, introduce it into the body cavity through the power circulating pump, and maintain the effective therapeutic temperature within the therapeutic time (e.g., 60 minutes) to give full play to the heat-killing mechanism; to give full play to the heat-killing mechanism. give full play to the heat-killing mechanism; carry out thermal scavenging of metastatic cancer cells widely planted on the plasma membrane, and add chemotherapeutic drugs with heat-sensitizing effect according to the characteristics of metabolic disorder of the cancer cells and damage of the genetic material after heat therapy, so as to prompt the cancer cells to stop dividing and eliminate the foci that trigger the cancerous effusion, and enable the plasma membrane to be repaired rapidly, so as to achieve the purpose of effective treatment of cancerous effusion. Computerized control system The whole process is dynamically controlled by the computer, which displays the current status and information, monitors and records the alarm information, and randomly displays the real-time trend curve. 2.Treatment modes A variety of treatment modes are available, including single-channel perfusion mode, cyclic perfusion mode and combined perfusion mode. It can be chosen flexibly according to the different conditions of patients. 3.Temperature control system Four high-precision temperature sensors, computerized multi-point precision temperature control. The temperature control system is composed of A-class PT100 platinum resistance temperature sensor and temperature transmitter. 4.Heating system Inductive non-contact heater, isolated heating, rapid warming, safety, high thermal efficiency, while providing effective heat reserves. 5.Circulation system Centrifugal pump power circulation system, can be adjusted in a wide range of flow, suitable for perfusion therapy under various conditions. 6.Safety and security system High temperature warning, over high temperature automatic protection function. Ideal practical value 6 points of advantages 1, short treatment course: average treatment 3-4 times, average hospitalization time 10 days; implement immediate treatment for high-risk cases of tumor. 2. Obvious efficacy: 92.1% effective rate of cancerous effusion control, 82% complete remission rate (1369/1670); 3. Stable long-term effect: 414 CR patients followed up, 318 cases survived >6 months (76.8%) Relapse rate 3.6% (15/414); 4. No sequelae that damage physiological function and directly jeopardize the life of the patient; 5. Reducing the toxic side effects of intravenous chemotherapy; 6. Reducing the toxic side effects of intravenous chemotherapy; 6. New means of treating malignant effusion, controlling the condition quickly, safe and reliable.
