Description

Technical Field

[0001] This utility model relates to the field of radiotherapy equipment, specifically a head and chest support and protection device for radiotherapy. Background Technology

[0002] When patients undergo radiotherapy to the head or chest, they need to lie flat on a carbon fiber plate. A radiotherapy positioning membrane is then applied to fix and restrain the patient's head or chest, minimizing displacement during radiotherapy and increasing its precision and effectiveness. In existing technologies, the carbon fiber plate has mounting holes or grooves. Clips or strips are used to secure the edge of the radiotherapy positioning membrane to the carbon fiber plate, thus pressing and restraining the patient.

[0003] In existing technologies, carbon fiber plates have multiple rows of mounting holes or grooves. By changing the fixing position of the clamps on both sides of the chest radiotherapy positioning membrane, the distance between the clamps can be adjusted to accommodate patients of different body sizes, thus providing better restraint. However, multiple rows of mounting holes or grooves still cannot flexibly adjust the distance between the clamps, which is a limitation. Utility Model Content
