The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] This utility model provides a radiation protection device for radiotherapy, such as... Figure 1-4As shown, the radiotherapy protective device includes: a support bed 1 for supporting radiotherapy patients; a U-shaped protective plate 2 detachably mounted on the support bed 1 for isolating radiotherapy rays; isolation plates 3 installed on both sides of the protective plate 2 for sealing the protective plate 2; an extension rail 5 fixed on the support bed 1 for supporting the protective plate 2; a handle 4 mounted on the protective plate 2, the handle 4 having anti-slip texture; and a limiting component disposed on the protective plate 2, the limiting component being used to stably connect the protective plate 2 and the extension rail 5.

[0023] In this embodiment, the support bed 1 is used to support the radiotherapy patient and ensure that the patient remains stable during treatment. The protective plate 2 is used to isolate the radiotherapy radiation and protect the patient's untreated areas. The U-shaped design can achieve multi-directional isolation protection. The isolation sheet 3 is used to close the opening of the protective plate 2, reduce the amount of radiation leakage from the gaps, and further enhance the protective effect. The extension rail 5 supports the protective plate 2 and allows the protective plate 2 to slide or adjust its position on the extension rail 5 so as to adjust the protection range according to the treatment situation. The handle 4 facilitates the operation of the protective plate 2 by medical staff, such as moving and adjusting its position, while ensuring the safety of operation. The limiting component is used to stably connect the protective plate 2 and the extension rail 5 to ensure the stability of the protective plate 2 when it moves and prevent it from falling off directly.

[0024] In a further preferred embodiment of the present invention, the limiting component includes a plurality of locking plates 6 fixed on the inner walls of both sides of the protective plate 2; ball bearings 7 embedded in the plurality of locking plates 6 on one side close to each other; and limiting grooves 8 provided at the top and bottom of the extension rail 5, wherein the plurality of ball bearings 7 are respectively located in the plurality of limiting grooves 8.

[0025] In this embodiment, when the protective plate 2 slides or adjusts its position along the extension rail 5, the ball bearings 7 embedded in the retaining plate 6 roll within the limiting groove 8. The design of the limiting groove 8 restricts the range of movement of the protective plate 2 on the extension rail 5. At the same time, the rolling of the ball bearings 7 reduces friction, making the movement of the protective plate 2 smoother. Through the cooperation of the ball bearings 7 and the limiting groove 8, it is ensured that the protective plate 2 can remain stable after the position is adjusted, and will not move or tip over due to accidents, thus improving the safety and stability of the device. The design of the limiting groove 8 restricts the range of movement of the protective plate 2, allowing medical personnel to accurately adjust the position and range of the protective plate 2 according to the treatment situation, thereby improving the accuracy and flexibility of the treatment.

[0026] In a further preferred embodiment of this utility model, there are two extension rails 5, which are located on both sides of the support bed 1. There are at least two protective plates 2, and multiple protective plates 2 can be connected end to end to increase the protection range. Each of the multiple protective plates 2 is provided with two locking mechanisms.

[0027] In this embodiment, in actual use, medical staff can select an appropriate number of protective plates 2 according to the patient's treatment needs and install them end to end on the extension rail 5 to increase the protection range. When the protective plate 2 is moved to the designated position, it is locked on the extension rail 5 by the locking mechanism to ensure that the protective plate 2 will not move or tip over during treatment. By connecting multiple protective plates 2 end to end, the protection range can be flexibly configured to meet the treatment needs of different patients. The design of the locking mechanism ensures that the protective plate 2 can be stably locked on the extension rail 5 after it is moved into place, which improves the safety and stability of the device.

[0028] In a further preferred embodiment of the present invention, the locking mechanism includes a threaded rod 9, a limiting plate 10, and an adjusting block 11. The threaded rod 9 is threadedly mounted on any one of the protective plates 2. The limiting plate 10 and the adjusting block 11 are respectively fixed at both ends of the threaded rod 9. An anti-slip pad that can contact any one of the extension rails 5 is fixed on the limiting plate 10.

[0029] In this embodiment, after the protective plate 2 is moved to the designated position, medical personnel can rotate the adjusting block 11 to rotate the threaded rod 9 on the protective plate 2 and push the limiting plate 10 closer to the extension rail 5. When the anti-slip pad on the limiting plate 10 is in close contact with the extension rail 5, the protective plate 2 is locked on the extension rail 5 and cannot move. When unlocking is required, simply rotate the adjusting block 11 in the opposite direction to separate the limiting plate 10 from the extension rail 5. Through the cooperation of the threaded rod 9, the limiting plate 10, and the anti-slip pad, the protective plate 2 is stably locked on the extension rail 5, ensuring the stability and safety of the protective plate 2 during treatment. The design of the adjusting block 11 allows medical personnel to easily rotate the threaded rod 9 to adjust the pressure between the limiting plate 10 and the extension rail 5, thereby realizing the locking and unlocking operation of the protective plate 2.

[0030] In a further preferred embodiment of the present invention, the top of the support bed 1 is provided with a groove 15 for defining the patient's lying position, and the bottom of the support bed 1 is fixed with a plurality of support legs 16, each of which is rotatably mounted with a movable wheel 17.

[0031] In this embodiment, the patient can lie in the groove 15 of the support bed 1 according to the treatment needs. The design of the groove 15 can ensure that the patient maintains the correct lying posture and position, thereby improving the treatment effect. At the same time, medical staff can easily move the support bed 1 using the moving wheels 17 to transfer it to different treatment areas or equipment, which improves the flexibility and convenience of the treatment process. The addition of the moving wheels 17 makes the support bed 1 easy to move and transfer, improving the flexibility and convenience of the device and reducing the labor intensity of medical staff.

[0032] In a further preferred embodiment of the present invention, the top of the support bed 1 is provided with a sliding groove 12, a slider 13 is slidably installed in the sliding groove 12, and a neck pillow 14 located on the top of the support bed 1 is installed on the top of the slider 13. The neck pillow 14 is used to support the patient's neck.

[0033] In this embodiment, medical staff can adjust the position of the slider 13 in the groove 12 according to the patient's specific needs and body shape, thereby changing the position of the neck pillow 14. In this way, the patient can adjust the neck pillow 14 to a suitable position according to their own comfort and treatment needs to support their neck and reduce the discomfort caused by prolonged lying down. By adjusting the position of the neck pillow 14, medical staff can ensure that the patient maintains the correct posture and position during treatment, thereby improving the treatment effect and accuracy.

[0034] In a further preferred embodiment of the present invention, openings are provided on both sides of the plurality of limiting grooves 8 to allow the ball bearings 7 to pass through, the slider 13 is convex in shape, and the top of the neck pillow 14 is covered with medical gauze for absorbing sweat.

[0035] In this embodiment, the opening design of the limiting groove 8 allows the ball bearing 7 to roll smoothly from one part of the limiting groove 8 to another during the movement of the protective plate 2 without obstruction. This ensures that the movement of the protective plate 2 on the extension rail 5 is smoother and more stable, facilitating the installation and removal of the protective plate 2. The convex shape allows the slider 13 to be installed more stably in the slide groove 12, preventing it from shaking or falling off during movement. At the same time, the convex shape of the slider 13 also provides a larger contact area, increasing the friction between the slider 13 and the slide groove 12, making the position of the slider 13 more stable. The medical gauze has good moisture absorption and breathability, which can absorb the sweat produced by the patient's neck in time, keeping the neck dry and comfortable. This helps to reduce neck discomfort caused by prolonged lying down and improves the patient's comfort.

[0036] In a further preferred embodiment of this utility model, the support bed 1, multiple protective plates 2, multiple handles 4, two extension rails 5, multiple clamping plates 6, multiple ball bearings 7, multiple threaded rods 9, multiple limiting plates 10, multiple adjusting blocks 11, sliders 13, neck pillows 14, multiple support legs 16 and multiple moving wheels 17 are all made of lead, and the multiple isolation plates 3 are all soft lead pads.

[0037] In this embodiment, key components such as the support bed 1, protective plate 2, and extension rail 5 are made of lead material, and soft lead pads are used as isolation sheets 3. This can significantly improve the protection against radiation and protect patients and medical staff from radiation damage. Lead material has high density and strength, which can enhance the overall structural stability of the device and ensure the stability and safety of the device during treatment.

[0038] In summary, compared with related technologies, this device, through the design of the support bed 1, detachable U-shaped protective plate 2, isolation plate 3, extension rail 5, handle 4, and limiting components, effectively isolates radiotherapy radiation and protects the patient in positions where treatment is not needed.
