Description

Technical Field

[0001] This invention relates to the field of medical bed technology, specifically a tumor radiotherapy bed with a protective structure. Background Technology

[0002] The tumor radiotherapy bed is an indispensable piece of equipment in tumor radiotherapy, mainly used to support patients to receive radiotherapy.

[0003] In existing technologies, most radiotherapy beds are fixed structures, which are inconvenient to adjust in height and angle, making it difficult to flexibly and accurately align with the radiation irradiation position, thus affecting the accuracy of radiotherapy positioning. Traditional radiotherapy beds are mostly fixed in structure, with inconvenient height and angle adjustment, making it difficult to accurately align with the irradiation position; at the same time, they lack reliable body positioning devices, and the patient's body position is prone to deviation, which cannot meet the requirements for precise radiotherapy. Therefore, the present invention provides a tumor radiotherapy bed with a protective structure. Summary of the Invention

[0004] The purpose of this invention is to provide a tumor radiotherapy bed with a protective structure to solve the problems mentioned in the background art.

[0005] The technical solution of this invention is: a tumor radiotherapy bed with a protective structure, comprising a main bed board and four support columns. Two adjustment grooves are formed at the bottom of the main bed board. Supporting sliding columns are slidably engaged within the adjustment grooves. Supporting top blocks are fixedly connected to the outer sides of the supporting sliding columns. A connecting base plate is fixedly connected to the bottom of the supporting top blocks. Sliding groove plates are fixedly connected to both sides of the connecting base plate. Side inner sliding columns are slidably engaged within the sliding groove plates. Side bottom blocks are fixedly connected to the outer sides of the side inner sliding columns. A supporting rotating plate is fixedly connected to the bottom of the side bottom blocks. Supporting side columns are fixedly connected to both sides of the support column plates. The column has a supporting sliding column that slides internally. A fixed top block is fixedly connected to the top of the supporting sliding column. One fixed top block is rotatably connected to a supporting rotating plate via a hinge. A self-locking roller is fixedly connected to the bottom of the supporting side column. A threaded rotating shaft is rotatably connected to the inner side of the supporting column plate. A threaded push plate is threadedly connected to the outer side of the threaded rotating shaft. A bottom rotating roller is fixedly connected to the top of the threaded push plate. A top rotating roller is fixedly connected between two fixed top blocks. A supporting rotating plate is rotatably connected between the top rotating roller and the bottom rotating roller. Inner sliders are fixedly connected to both sides of the threaded push plate. A fixed side groove plate is fixedly connected between the two supporting side columns. A fixed middle plate is fixedly connected to the inner side of the fixed side slot plate. The inner side of the fixed middle plate has a groove that matches the inner slider. The inner slider slides and engages within the groove. A rotating plate is fixedly connected to the outer side of the threaded shaft. An inner sliding post is slidably engaged with the inner side of the threaded shaft. One end of the inner sliding post is fixedly connected to a connecting post, which engages with another threaded shaft. In use: When adjusting the height and angle, rotating the rotating plate rotates the threaded shaft, which in turn moves the threaded push plate. The threaded push plate is limited by the inner slider. When the threaded push plate approaches the supporting rotating plate, it causes the supporting rotating plate to rotate. Rotating the plate causes the fixed top block to rise, and the supporting sliding column slides inside the supporting side column. The supporting rotating plate is set with four diagonally opposite plates. When rotating to adjust two opposite threaded rotating shafts, the main bed plate on that side will rise and tilt to adjust the angle. This is achieved through the rotational connection of the supporting rotating plate and the sliding connection between the inner sliding column and the inner side of the sliding groove plate, which can prevent the main bed plate from sliding down naturally. Similarly, when adjusting two adjacent threaded rotating shafts, one end of the main bed plate will tilt up. This is achieved through the sliding connection of the supporting sliding column at the bottom of the main bed plate, which allows for adjustment of the angle and height of the main bed plate. By setting the inner sliding column and connecting column, the opposite two threaded rotating shafts can rotate synchronously.

[0006] Preferably, a fixed pillow is fixedly connected to the top of the main bed board, a fixed slide rail is slidably engaged inside the fixed pillow, and a fixed strap is rotatably connected to the outside of the fixed slide rail. A fixed buckle is provided at the top of the main bed board. Protective side panels are rotatably connected to both sides of the main bed board via hinges. A protective inner panel is slidably engaged inside the protective side panel. A protective side strip is fixedly connected to the top of the protective inner panel. A threaded push shaft is rotatably connected to the inside of the protective side strip, and the threaded push shaft is threadedly connected to the protective side panel. A protective groove frame is rotatably connected to the bottom of the protective side strip via hinges. A protective sliding plate is attached to the inner side, and a protective half-cylinder is fixedly connected to one side of the protective sliding plate. In use: a right-angle protective cover can be formed by setting the protective side plate and the protective groove frame. Cover cloth is set on both sides of the protective sliding plate, and the two protective half-cylinders form a circle, so that the device can be inserted between the two protective half-cylinders. At the same time, the protective sliding plate can slide inside the protective groove frame to adjust its position. By setting a threaded push shaft, the height of the protective side strip is adjusted by pushing the thread, thereby adjusting the height of the protective side strip and thus the height of the protective half-cylinder. The patient's body can be fixed by setting a fixing strap to fix the head and installing a fixing strap on the fixing buckle.

[0007] This invention provides an improved tumor radiotherapy bed with a protective structure, which has the following improvements and advantages compared with the prior art:

[0008] Firstly, the tumor radiotherapy bed with a protective structure described in this invention allows for height and angle adjustments by rotating a rotating plate, which in turn rotates a threaded shaft. This, in turn, moves a threaded push plate via the threaded shaft. The threaded push plate is limited by an inner slider. When the threaded push plate approaches the supporting rotating plate, it causes the supporting rotating plate to rotate, raising the fixed top block. The supporting sliding column slides inside the supporting side column. The supporting rotating plate has four diagonally arranged supports. When adjusting two opposing threaded shafts, the main bed board on that side will rise and tilt to adjust the angle. This is achieved through the rotational connection of the supporting rotating plate and the sliding connection between the inner sliding column and the inner side of the sliding groove plate, preventing the main bed board from slipping off naturally. Similarly, when adjusting two adjacent threaded shafts, one end of the main bed board will tilt up. This is achieved through the sliding connection between the supporting sliding column and the bottom of the main bed board, allowing for adjustment of the angle and height of the main bed board. By setting inner sliding columns and connecting columns, the opposing threaded shafts can rotate synchronously.

[0009] Secondly, the tumor radiotherapy bed with protective structure described in this invention can form a right-angle protective cover by setting protective side plates and protective groove frames. Cover cloths are set on both sides of the protective sliding plate, and two protective half cylinders form a circle, so that the equipment can be inserted between the two protective half cylinders. At the same time, the protective sliding plate can slide inside the protective groove frame to adjust its position. By setting a threaded push shaft, the height of the protective side strip is adjusted by pushing the threaded side strip, thereby adjusting the height of the protective half cylinder. The patient's body can be fixed by setting a fixing strap to fix the head and installing a fixing strap on the fixing buckle.

[0010] In summary, the tumor radiotherapy bed with protective structure described in this invention has a reasonable design and is easy to operate. The height and angle of the bed can be flexibly adjusted to facilitate precise alignment with the radiation irradiation position. The protective components can be adapted to the lesion for precise shielding, effectively reducing radiation scattering damage to normal tissues. Combined with head fixation and body straps, it can improve positional stability, thereby improving treatment safety while ensuring treatment effectiveness. Attached Figure Description

Detailed Implementation

[0022] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] This invention provides an improved tumor radiotherapy bed with a protective structure. The technical solution of this invention is as follows:

[0024] like Figures 1-8As shown, a tumor radiotherapy bed with a protective structure includes a main bed board 1 and four support column plates 34. The bottom of the main bed board 1 has two adjustment grooves. Supporting sliding columns 23 are slidably engaged within the adjustment grooves. Supporting top blocks 22 are fixedly connected to the outer sides of the supporting sliding columns 23. A connecting base plate 24 is fixedly connected to the bottom of the supporting top blocks 22. Sliding groove plates 25 are fixedly connected to both sides of the connecting base plate 24. Side inner sliding columns 11 are slidably engaged within the sliding groove plates 25. Side bottom blocks 10 are fixedly connected to the outer sides of the side inner sliding columns 11. A supporting rotating plate 9 is fixedly connected to the bottom of the side bottom blocks 10. Supporting side columns 5 are fixedly connected to both sides of the support column plates 34. Supporting sliding columns are slidably engaged within the supporting side columns 5. 7. A fixed top block 8 is fixedly connected to the top of the supporting sliding column 7. One fixed top block 8 is rotatably connected to the supporting rotating plate 9 via a hinge. A self-locking roller 18 is fixedly connected to the bottom of the supporting side column 5. A threaded rotating shaft 17 is rotatably connected to the inner side of the supporting column plate 34. A threaded push plate 15 is threadedly connected to the outer side of the threaded rotating shaft 17. A bottom rotating roller 14 is fixedly connected to the top of the threaded push plate 15. A top rotating roller 12 is fixedly connected between the two fixed top blocks 8. A supporting rotating plate 13 is rotatably connected between the top rotating roller 12 and the bottom rotating roller 14. Inner sliders 16 are fixedly connected to both sides of the threaded push plate 15. A fixed side groove plate 6 is fixedly connected between the two supporting side columns 5. A fixed side groove plate 6 is fixedly connected to the inner side of the fixed side groove plate 6. The center plate 33 has a groove on its inner side that matches the inner slider 16. The inner slider 16 is slidably engaged in the groove. A rotating plate 19 is fixedly connected to the outer side of the threaded shaft 17. An inner sliding post 20 is slidably engaged on the inner side of the threaded shaft 17. A connecting post 21 is fixedly connected to one end of the inner sliding post 20. The connecting post 21 is engaged with another threaded shaft 17. In use: when the height and angle need to be adjusted, the rotating plate 19 is rotated, which drives the threaded shaft 17 to rotate. The threaded push plate 15 is moved through the thread. The threaded push plate 15 is limited by the inner slider 16. When the threaded push plate 15 approaches the supporting rotating plate 9, it will cause the supporting rotating plate 13 to rotate, thus fixing the top. When block 8 rises, the supporting slide column 7 slides inside the supporting side column 5. The supporting rotating plate 9 is set in four diagonal positions. When rotating to adjust the two threaded rotating shafts 17, the main bed plate 1 will rise on that side and tilt to adjust the angle. The supporting rotating plate 9 is rotated to adapt to the connection, and the inner sliding column 11 is slidably connected to the inner side of the sliding groove plate 25. This can prevent the main bed plate 1 from sliding down naturally. Similarly, when adjusting the two adjacent threaded rotating shafts 17, one end of the main bed plate 1 will tilt up. The supporting slide column 23 is slidably connected to the bottom of the main bed plate 1. This allows the angle and height of the main bed plate 1 to be adjusted. By setting the inner sliding insert 20 and the connecting insert 21, the two opposing threaded rotating shafts 17 can rotate synchronously.

[0025] Furthermore, a fixed pillow 2 is fixedly connected to the top of the main bed board 1. A fixed slide strip 26 is slidably engaged inside the fixed pillow 2. A fixed strap 27 is rotatably connected to the outside of the fixed slide strip 26. A fixed buckle is provided at the top of the main bed board 1. Protective side panels 3 are rotatably connected to both sides of the main bed board 1 via hinges. A protective inner panel 30 is slidably engaged inside the protective side panel 3. A protective side strip 31 is fixedly connected to the top of the protective inner panel 30. A threaded push shaft 32 is rotatably connected to the inside of the protective side strip 31. The threaded push shaft 32 is threadedly connected to the protective side panel 3. A protective groove frame 4 is rotatably connected to the bottom of the protective side strip 31 via hinges. A protective groove frame 4 is slidably engaged inside the protective groove frame 4. The protective slide plate 28 has a protective half-cylinder 29 fixedly connected to one side. In use: a right-angle protective cover can be formed by setting the protective side plate 3 and the protective groove frame 4. Cover cloths are set on both sides of the protective slide plate 28. The two protective half-cylinders 29 form a circle, allowing the device to be inserted between the two protective half-cylinders 29. At the same time, the protective slide plate 28 can slide inside the protective groove frame 4 to adjust its position. By setting the threaded push shaft 32, the height of the protective side strip 31 can be adjusted by pushing the threaded push shaft 32. In turn, the height of the protective side strip 31 can be adjusted, thereby adjusting the height of the protective half-cylinder 29. The head can be fixed by setting the fixing strap 27 and the patient's body can be fixed by installing the fixing strap on the fixing buckle.

[0026] Working principle: In use: When the height and angle need to be adjusted, rotating the rotating plate 19 drives the threaded shaft 17 to rotate, which in turn drives the threaded push plate 15 to move. The threaded push plate 15 is limited by the inner slider 16. When the threaded push plate 15 approaches the supporting rotating plate 9, it will cause the supporting rotating plate 13 to rotate, causing the fixed top block 8 to rise. The supporting sliding column 7 slides inside the supporting side column 5. The supporting rotating plate 9 has four diagonally arranged plates. When rotating to adjust two relative threaded shafts 17, the main bed plate 1 will rise on that side for tilt adjustment. The angle is adjusted by the rotation of the supporting rotating plate 9 and the sliding connection between the inner sliding column 11 and the inner side of the sliding groove plate 25. This prevents the main bed plate 1 from slipping off naturally. Similarly, when adjusting two adjacent threaded shafts 17, one end of the main bed plate 1 will tilt up. The sliding column 23 is slidably connected to the bottom of the main bed board 1, thereby allowing adjustment of the angle and height of the main bed board 1. By setting the inner sliding column 20 and the connecting column 21, the two opposing threaded shafts 17 can rotate synchronously. By setting the protective side plate 3 and the protective groove frame 4, a right-angle protective cover can be formed. Cover cloths are set on both sides of the protective slide plate 28. Two protective half cylinders 29 form a circle, allowing the equipment to be inserted between the two protective half cylinders 29. At the same time, the protective slide plate 28 can slide inside the protective groove frame 4 to adjust its position. By setting the threaded push shaft 32, the protective side strip 31 is pushed by the thread to adjust the height of the protective side strip 31, thereby adjusting the height of the protective half cylinder 29. The patient's body can be fixed by setting the fixing strap 27 to fix the head and installing the fixing strap on the fixing buckle.
