Description

Technical Field

[0001] The utility model relates to the field of medical equipment, and more specifically, to a wing-shaped support plate used for making a foam rubber positioning pad. Background Art

[0002] Radiotherapy is one of the main treatments for malignant tumors. At present, advanced radiotherapy technology makes the tumor target area more and more accurate. The premise for achieving accurate treatment is that the patient needs to have a good position fixation. Different radiotherapy equipment requires different position fixation devices to achieve more accurate radiotherapy target area, less dose to surrounding normal tissue, improve patient comfort and repeatability of treatment, and reduce positioning errors during treatment. Therefore, good position fixation is the key to implementing treatment. Breast cancer radiotherapy positioning should select appropriate position and fixation device according to the patient's radiotherapy range and the activity of the affected upper limb. Polyurethane foam positioning pad is a commonly used position fixation device. The softness of foam can achieve stable fixation of objects.

[0003] During radiotherapy for breast cancer, the patient's position can be effectively fixed and individualized by mixing foam glue and waterproof bags, which can significantly improve the repeatability and stability of position fixation, ensure the accuracy of the patient's position for each radiotherapy session, and receive radiation exposure in the most accurate position. In the prior art, when a polyurethane foam positioning pad is used for fixation during radiotherapy for breast cancer, the patient should remain in a supine position, with the head in the middle and the hands crossed and the elbows placed on the forehead. The prior art lacks a stable and effective auxiliary device to ensure the fixation of the patient's arm position. Before the polyurethane foam is cooled and set, it is necessary to manually use cardboard to lift it, which takes 5-10 minutes. This method usually requires three people to assist in completion. On the one hand, it reduces the efficiency of position fixation, and on the other hand, due to differences in personal experience, the accuracy of the position cannot be guaranteed.

[0006] During radiotherapy, the patient should remain in a supine position with the head in the middle and the hands crossed with the elbows placed on the forehead. The first wing-shaped support plate and the second wing-shaped support plate are respectively placed on both sides of the patient's body, located at the head, neck and shoulders, to support the patient's arms. The accommodation interval is used to accommodate a waterproof bag filled with polyurethane foam. The first support plate is used to raise the second support plate to reach the height of the arm. The second support plate has a certain angle with the horizontal plane, which can support the tilted arm and better match the patient's body position. When in use, first place the first wing-shaped support plate and the second wing-shaped support plate, and then put on the waterproof bag filled with unformed polyurethane foam. The first wing-shaped support plate, the second wing-shaped support plate and the accommodation interval are covered, and the patient lies on his back on the waterproof bag, waiting for the polyurethane foam to cool and set, and then remove the first wing-shaped support plate and the second wing-shaped support plate.
