Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a hyperthermia warming device. Background Art

[0002] With the vigorous development of China's economy, the living standards of the people have been continuously improved, the medical security system has been continuously improved, and the average life expectancy has been significantly extended. At the same time of this positive change, the incidence of tumor diseases has also shown an upward trend. The increase in the number of tumor patients has brought many challenges to the medical field, and the treatment of malignant ascites and pleural effusion has become a difficult problem to be solved urgently.

[0003] In many clinical departments such as thoracic surgery, general surgery, and gynecology, a large number of tumor patients are found to be accompanied by malignant ascites and pleural effusion. Malignant ascites and pleural effusion refer to the abnormal accumulation of fluid in the abdominal or thoracic cavity caused by malignant tumors. For tumor patients in thoracic surgery, common diseases such as lung cancer and esophageal cancer often cause malignant pleural effusion when they progress to a certain stage. The accumulation of pleural effusion will compress the lung tissue, resulting in symptoms such as difficulty in breathing and chest pain in patients, seriously affecting the respiratory function, reducing the quality of life of patients, and even threatening life. For example, among patients with advanced lung cancer, about 50% will have malignant pleural effusion, which not only increases the complexity of treatment, but also indicates the deterioration of the condition and poor prognosis.

[0004] For tumors in the above situation, hyperthermia is generally used for treatment. Hyperthermia is to pump hot water at 39 to 41 degrees Celsius into the thoracic or abdominal cavity with a pump, drain the hot water back and reheat it and then pump it into the body. Since tumor cells are severely intolerant to high temperatures of 39 to 41 degrees Celsius, tumor cells can be effectively killed, and at the same time, the side effects are much smaller than those of chemotherapy and radiotherapy. Conventional hyperthermia requires a water tank to heat the hyperthermia device, and the water tank is expensive and a burden; some units also use a membrane lung as a hyperthermia consumable, because the oxygenation part of the extracorporeal membrane lung not only has a gas exchange function but also has a temperature-changing effect. However, the hollow fibers of the current membrane lung are relatively expensive, and more importantly, its production technology is highly monopolized globally, and all production in the world is concentrated in Germany and Japan, which greatly restricts its application in China. Moreover, membrane lung warming will cause a "water mixing" phenomenon with the water tank on it, affecting the circulation function of the membrane lung. Summary of the Invention
