Description

Technical Field

[0001] The present invention relates to the technical field of breathing guidance, and in particular to a breathing guidance device used in a three-dimensional conformal radiotherapy process for liver cancer. Background Art

[0002] Hepatocellular carcinoma, also known as liver cancer, is the most common type of primary liver cancer, and its incidence ranks high among malignant tumors worldwide. The disease mainly originates from hepatocytes in the liver and becomes malignant after multiple cycles of necrosis and regeneration. The causes of the disease are complex and diverse, including viral hepatitis infection (such as hepatitis B and hepatitis C), alcoholism, exposure to chemical carcinogens such as aflatoxin, and water and soil factors. The clinical manifestations of hepatocellular carcinoma are variable. There may be no obvious symptoms in the early stage, and symptoms such as liver pain, liver enlargement, and jaundice may appear in the late stage. Treatment methods include surgical resection, liver transplantation, local ablation, chemoembolization, radiotherapy, etc. The specific choice depends on the stage of cancer and the patient's physical condition. Due to the high recurrence and metastasis rates of hepatocellular carcinoma and the relatively poor prognosis, early detection and treatment are crucial.

[0003] Hepatocellular carcinoma faces certain problems when receiving radiotherapy, namely, normal liver cells are more likely to necrotize after receiving radiotherapy, thus causing liver damage. In addition, when receiving radiotherapy for hepatocellular carcinoma, there will be radiation effects on the surrounding gallbladder, bile duct, chest cavity and important blood vessels. Among them, in addition to the fact that liver cells themselves are sensitive to radiation and are prone to liver damage, the patient's own abdominal breathing will cause the liver and radiation targets to move up and down, resulting in the off-target effect of radiotherapy, which can easily cause damage to surrounding normal tissues. Therefore, a breathing guidance device is needed for use in the process of three-dimensional conformal radiotherapy for liver cancer to encourage patients to perform chest breathing, or reduce the amplitude of abdominal breathing, so as to promote three-dimensional radiotherapy to more effectively irradiate the target lesions and reduce the damage caused by radiotherapy to surrounding normal tissues. Summary of the invention

[0004] The main purpose of the present invention is to provide a breathing guidance device used in three-dimensional conformal radiotherapy of liver cancer, which can effectively solve the problems in the background technology.

[0005] To achieve the above object, the technical solution adopted by the present invention is: A breathing guide device for use in three-dimensional conformal radiotherapy of liver cancer comprises an abdominal breathing detection device and an alarm device.

When in use, the abdominal breathing detection device 1 can be fixed to the patient's abdomen through the elastic tightening belt 2, the installation connecting cloth 3, the first fixing component 4, and the second fixing component 5. The method is to first stick the abdominal breathing detection device 1 to the patient's abdomen, then wrap the elastic tightening belt 2 and the installation connecting cloth 3 around the patient's waist, and finally install and fix the first fixing component 4 and the second fixing component 5 together. At this time, the abdominal breathing detection device 1 is fixed to the patient's abdomen. At the same time, the soft elastic sleeve 7 can be put on the patient's arm to fix the alarm device 6 on the patient's arm. During use, specified parameters can be set.
