Description

Technical Field

[0001] The utility model relates to the technical field of tumor thermotherapy machines, and particularly relates to a body surface heat dissipation device for tumor thermotherapy. Background Technique

[0002] The incidence of tumors in each system is increasing year by year and tends to be younger. In order to improve the treatment effect of tumors, the treatment mode has developed towards the combined application of multiple treatment means. Thermotherapy is the fifth major tumor treatment means after surgery, radiotherapy, chemotherapy and biological treatment. It is clinically applied without toxicity, safe and efficient, and is called green treatment. The combined application of thermotherapy and chemoradiotherapy improves the treatment effect of tumors and is now widely used in clinical practice.

[0003] Within 5 - 10 minutes after the start of thermotherapy, the body surface temperature projected by the tumor on the body surface of the tumor thermotherapy machine is (40 ± 1) °C (the temperature at the center of the tumor is about 3 °C higher than the body surface temperature). The temperature at the center of the tumor will rise to the effective treatment temperature (above 43 °C), and the body surface temperature is adjusted according to the output power to keep the body surface temperature constant at about 40 °C for 40 - 60 minutes. In order to ensure that the temperature inside the tumor reaches the treatment effect (above 43 °C), the body surface temperature projected by the tumor will exceed the tolerance of the patient's skin due to the heat accumulation effect, resulting in scald symptoms such as fat induration, blisters, and in severe cases, skin ulceration, aggravating the skin reaction of thermotherapy.

[0004] Therefore, there is an urgent need to invent a heat dissipation device that can reduce the body surface temperature, relieve the skin reaction of thermotherapy, and relieve the pain of patients. Content of the Utility Model
