Description

Technical Field

[0001] This utility model relates to the field of medical linear accelerator technology, specifically to an anti-collision protection device for linear accelerators. Background Technology

[0002] Medical linear accelerators are medical devices widely used in radiotherapy for tumors. During treatment, the rotating gantry of the linear accelerator rotates under the drive of the gantry rotation system to treat the patient. Due to the large size of the equipment, it is easy for the rotating gantry to collide with surrounding medical staff, equipment and patients during rotation. For safety reasons, anti-collision protection devices are usually installed on the rotating gantry of the linear accelerator.

[0003] Application number CN202310981063.9 discloses a collision protection device for a medical linear accelerator. Through a control device, when the rotating frame rotates, the control device activates the collision protection device. The control device inflates the airbag on the collision protection component, causing it to expand. The inflated airbag provides cushioning protection; when a person bumps into the rotating frame, the expanded airbag cushions their impact. Furthermore, a whistle sounds during inflation to warn personnel to stay away from the rotating frame, thus serving both a warning and protective function. However, this design has shortcomings. The radiator head is mounted on the lower end of one end of the rotating frame, and the radiator head lacks a protective mechanism, making it vulnerable to impacts. Additionally, one end of the rotating frame has a sharp corner, posing a safety hazard.

[0004] Therefore, we propose a collision protection device for electronic linear accelerators. Utility Model Content

[0005] The main objective of this invention is to provide a collision protection device for an electron linear accelerator.
