Description

A radiotherapy protective bed with convenient control

technical field

The invention relates to a protective bed, in particular to a radiotherapy protective bed with convenient regulation and control.

Background technique

Radiation therapy for tumors is a local treatment method that uses radiation to treat tumors. Radiation includes α, β, γ rays produced by radioactive isotopes and x-rays, electron beams, proton beams and other particle beams produced by various x-ray therapy machines or accelerators. About 70% of cancer patients need radiotherapy in the course of cancer treatment, and about 40% of cancers can be cured with radiotherapy. The role and status of radiotherapy in tumor treatment has become increasingly prominent, and it has become one of the main means of treating malignant tumors.

The curative effect of radiotherapy depends on radiosensitivity, and different tissues and organs and various tumor tissues have different responses to changes after being irradiated. Radiosensitivity is related to the proliferation cycle and pathological grade of tumor cells, that is, actively proliferating cells are more sensitive than non-proliferating cells, and the higher the degree of cell differentiation, the lower the radiosensitivity, and vice versa. In addition, the oxygen content of tumor cells directly affects radiosensitivity. For example, early tumors are small in size and have good blood supply, and the curative effect is good when there are few hypoxic cells. In late tumors, the volume is large, the blood supply in the tumor is poor, and even the center has necrosis. Low; localized squamous cell carcinomas have better blood supply than tumors in the buttocks and extremities, and have higher sensitivity; local tumors are infected with poor blood supply (more hypoxic cells), and radiosensitivity decreases. In the prior art, in the traditional radiotherapy process, most of the normal parts of the patient are not prevented with too much radiotherapy and radiation. After the radiation acts on the tumor cells, the DNA in the cells will be destroyed, and a large number of tumor cells will be killed. When radiotherapy When the radiation produced kills the patient's tumor cells, the radiation will not only prevent the growth and division of cancer cells, but also destroy the growth and proliferation of normal cells. Side effects are unavoidable due to radiotherapy radiation patients, so how to reduce the damage of radiation to normal cells during radiotherapy of patients is especially important. For the above problems, the present invention is specially designed to solve it.
