Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a radiotherapy positioning pad for preventing patients from moving autonomously. Background Art

[0002] Radiotherapy is a medical method that uses radiation to kill tumor cells and control tumor growth. In cancer treatment, radiotherapy can be used as the main treatment method, such as nasopharyngeal carcinoma of the head and neck; it can also be used as an auxiliary treatment method, such as to further reduce the risk of tumor recurrence after surgery, such as colon cancer, cervical cancer and breast cancer; it can also be used as a palliative treatment method. For example, when bone metastasis or brain metastasis occurs in advanced malignant tumors, radiotherapy can significantly improve the patient's symptoms and quality of life. During radiotherapy, in order to ensure the accuracy of the radiotherapy irradiation position, the patient needs to remain still. During radiotherapy, the patient is mostly in a lying position, but in the lying position, the patient's waist cannot fully contact the bed surface, which will cause the patient to have waist pain and subconsciously twist the waist to relieve it. Secondly, each patient has a different lying position, and the commonly used leg limiter cannot be adjusted in multiple ways. In response to the above problems, the inventor proposes a radiotherapy positioning pad that prevents the patient from moving autonomously to solve the above problems. Utility Model Content
