Abstract
Description
Technical Field
[0001] This utility model relates to the field of radiotherapy equipment technology, and more specifically, to a radiotherapy bed board. Background Technology
[0002] As one of the three major methods of cancer treatment, radiotherapy involves the radiation equipment generating radiation and precisely focusing it on the tumor. At this time, it is necessary to make a personalized fixation mold according to the patient's physical condition and treatment needs to temporarily restrict and fix the patient's body, so as to maintain the positioning accuracy of the equipment and the patient's lesion to the greatest extent.
[0003] Currently, vacuum shaping pads are a commonly used fixation device for patients. When using it for the first time, the vacuum shaping pad is placed on the surface of the radiotherapy bed, with the pad under the patient. Then, the air is removed, and the vacuum pad will conform to the patient's body contour. Finally, lines are drawn on the side of the vacuum shaping pad to determine its relative position to the radiotherapy bed for future use. However, because there is no fixed structure between the vacuum shaping pad and the bed, the vacuum shaping pad can slide on the bed surface. This can cause the vacuum shaping pad to shift during radiotherapy, making it difficult to effectively locate the lesion and resulting in lower precision in tumor treatment. Therefore, there is an urgent need to improve this. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a radiotherapy bed board. By setting a headrest, a first positioning component, and a second positioning component, the vacuum shaping pad can be positioned and limited, so that the relative position of the vacuum shaping pad and the bed board is highly consistent when reused, and the vacuum shaping pad is prevented from sliding during radiotherapy.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a radiotherapy bed board, including a main board, a headboard on the side of the main board, a head pillow fixed on the upper part of the headboard, a first positioning member on the surface of the headboard, the first positioning member being located on both sides of the head pillow, one end of the first positioning member extending beyond the head pillow towards the main board, a second positioning member on the upper part of the main board, the second positioning member being connected to the main board through a connecting plate, the connecting plate being connected to the side of the main board away from the headboard.
[0006] Furthermore, the first positioning component includes an L-shaped locking block, one end of the horizontal area of the L-shaped locking block extends beyond one side of the headrest, the horizontal area of the L-shaped locking block is positioned higher than the surface of the headboard, and a base is provided at the lower part of the vertical area of the L-shaped locking block, with the lower part of the base abutting against the upper part of the headboard.
[0007] Furthermore, the head plate surface is provided with a first strip groove corresponding to the first positioning member, the side of the first strip groove is provided with a limiting groove, the lower part of the base is provided with a protrusion, the side of the protrusion is provided with a limiting rib, the protrusion is inserted into the first strip groove and tightly fitted with the side wall of the first strip groove, and the limiting rib is inserted into the limiting groove for limiting.
[0008] Furthermore, the connecting plate has a first protrusion on its side, the lower part of the first protrusion abuts against the upper part of the main board, and the side of the main board is fixed to the connecting plate by bolts.
[0009] Furthermore, the second positioning member is connected to the connecting plate by a screw, the screw passing through the connecting plate, and the screw and the connecting plate are fixedly connected by a nut.
[0010] Furthermore, a second groove is provided on the upper part of the motherboard near both sides, and a baffle is provided on the upper part of the motherboard. The lower part of the baffle is inserted into the second groove, and the baffle can move along the second groove.
[0011] Furthermore, the second groove includes a vertical section and a horizontal section, and the lower part of the baffle is provided with a rib. The baffle is inserted into the vertical section and the rib is inserted into the horizontal section.

[0014] In summary, this utility model has the following beneficial effects:
[0015] When a patient uses the device for the first time, the unvacuum-sealed vacuum shaping pad is placed on the top of the main board, with one side of the pad abutting the side of the headrest. The horizontal area of the L-shaped locking block compresses the surface of the vacuum shaping pad, creating a first positioning groove. The second positioning element compresses the side of the vacuum shaping pad, creating a second positioning groove in its area. After placing the vacuum shaping pad, the patient lies flat on it. The pad is compressed by the patient, creating a groove on its surface that conforms to the patient's body shape. Finally, the vacuum shaping pad is vacuumed, transforming it from a "cushion" shape. As a "rigid pad," after the vacuum shaping pad is evacuated, its surface forms a first positioning groove corresponding to the first positioning element, a second positioning groove corresponding to the second positioning element, and a groove that matches the patient's body shape. When used again, simply insert the first positioning element into the first positioning groove, the second positioning element into the second positioning groove, and have the patient lie in the groove that matches their body shape. This allows the vacuum shaping pad to be positioned and limited, ensuring a high degree of consistency in the relative positions of the vacuum shaping pad, the bed board, and the patient during reuse. This prevents the vacuum shaping pad from slipping during radiotherapy and improves the success rate of radiotherapy. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figures 1 to 6 As shown, this embodiment discloses a radiotherapy bed board, including a main board 1, a headboard 11 on the side of the main board 1, and a head pillow 2 fixed on the upper part of the headboard 11. The head pillow 2 is glued and fixed to the headboard 11.
[0025] like Figure 1 , Figure 2 and Figure 5 As shown, the headboard 11 has a first positioning element 3 on its surface. The first positioning element 3 is located on both sides of the headrest 2. One end of the first positioning element 3 extends beyond the headrest 2 towards the main board 1. Specifically, the first positioning element 3 includes an L-shaped locking block 31. One end of the horizontal section of the L-shaped locking block 31 extends beyond the headrest 2. The horizontal section of the L-shaped locking block 31 is higher than the surface of the headboard 11. A base 32 is provided at the lower part of the vertical section of the L-shaped locking block 31. The lower part of the base 32 abuts against the upper part of the headboard 11. The surface of the headboard 11 has a first groove 12 corresponding to the first positioning element 3. The first strip groove 12 has a limiting groove 121 on its side, and the base 32 has a protrusion 33 at its lower part. The protrusion 33 has a limiting rib 34 on its side. The protrusion 33 is inserted into the first strip groove 12 and fits tightly with the side wall of the first strip groove 12. The limiting rib 34 is inserted into the limiting groove 121 for limiting. The first positioning member 3 and the first strip groove 12 are connected by a plug-in connection, which facilitates the disassembly and assembly of the first positioning member 3 and the head plate 11. Through the cooperation of the limiting groove 121 and the limiting rib 34, the first positioning member 3 can be limited, thereby improving the installation effect of the first positioning member 3.
[0026] like Figure 1 and Figure 3As shown, the upper part of the main board 1 is provided with a second positioning component 4. The second positioning component 4 is connected to the main board 1 through a connecting plate 5. The connecting plate 5 is connected to the side of the main board 1 away from the head plate 11. Specifically, the side of the main board 1 is connected and fixed to the connecting plate 5 by bolts 52. The second positioning component 4 is connected to the connecting plate 5 by a screw 6. One end of the screw 6 passes through the connecting plate 5, and the other end is inserted into the second positioning component 4 for fixation. The screw 6 is fixedly connected to the connecting plate 5 by nuts 61. When assembling the main board 1, the connecting plate 5, and the second positioning component 4, first, the connecting plate 5 is connected and fixed to the main board 1 by bolts 52. Then, the screw 6 passes through the connecting plate 5. After adjusting the position of the second positioning component 4, the two nuts 61 located on the same screw 6 are turned so that the two nuts 61 abut against the two sides of the connecting plate 5 respectively, thereby completing the fixation of the second positioning component 4 and the connecting plate 5. Through the above design, not only is the connection simple and convenient, but the position adjustment of the second positioning component 4 can also be realized.
[0027] The connecting plate 5 has a first protruding plate 51 on its side. The lower part of the first protruding plate 51 abuts against the upper part of the main board 1. By setting the first protruding plate 51, the strength of the connecting plate 5 can be improved, and the fixing effect between the connecting plate 5 and the main board 1 can be improved.
[0028] like Figure 6 As shown, when a patient uses it for the first time, the unvacuumed vacuum shaping pad 100 is first placed on the upper part of the main board 1, with one side of the vacuum shaping pad 100 abutting the side of the headrest 2. The horizontal area of the L-shaped locking block 31 can compress the surface of the vacuum shaping pad 100, forming a first positioning groove on the surface of the vacuum shaping pad 100. The second positioning member 4 can compress the side of the vacuum shaping pad 100, forming a second positioning groove in the area of the second positioning member 4. After the vacuum shaping pad 100 is placed, the patient lies flat on the vacuum shaping pad 100. The vacuum shaping pad 100 is compressed by the patient, and a groove conforming to the patient's body shape will be formed on its surface. Finally, the vacuum shaping pad 100 is vacuumed. This process transforms the "soft pad" into a "hard pad." After the vacuum shaping pad 100 is evacuated, a first positioning groove corresponding to the first positioning member 3, a second positioning groove corresponding to the second positioning member 4, and a groove consistent with the patient's body shape will be formed on the surface of the vacuum shaping pad 100. When used again, simply insert the first positioning member 3 into the first positioning groove, insert the second positioning member 4 into the second positioning groove, and have the patient lie in the groove consistent with the patient's body shape. This will position and limit the vacuum shaping pad 100, ensuring a high degree of consistency in the relative positions of the vacuum shaping pad 100, the bed board 1, and the patient when used again. This will prevent the vacuum shaping pad 100 from sliding during radiotherapy and improve the success rate of radiotherapy.
[0029] like Figure 4As shown, the upper part of the main board 1 is provided with a second strip groove 13 near both sides, and the upper part of the main board 1 is provided with a baffle 7. The lower part of the baffle 7 is inserted into the second strip groove 13. The baffle 7 can move along the second strip groove 13. Specifically, the second strip groove 13 includes a vertical section 131 and a horizontal section 132. The lower part of the baffle 7 is provided with a rib 71. The baffle 7 is inserted into the vertical section 131 and the rib 71 is inserted into the horizontal section 132. By setting the baffle 7, the left and right sides of the vacuum shaping pad 100 can be limited, thereby improving the limiting effect when the vacuum shaping pad 100 is placed on the main board 1.
[0030] In this embodiment, a second protruding plate 72 is provided on the side of the baffle 7 away from the protruding rib 71. The lower part of the second protruding plate 72 abuts against the upper surface of the main plate 1. In this embodiment, the dimensions are a = 12 mm, b = 18 mm, c = 10 mm, d = 18 mm, and e = 14 mm. Through the above design, not only can the lower part of the baffle 7 be smoothly inserted into the second strip groove 13, but also when the left side of the baffle 7 abuts against the left side of the vertical section 131, the protruding rib 71 is inserted into the horizontal section 132 by 2 mm. Furthermore, through the cooperation between the second protruding plate 72 and the upper surface of the main plate 1, the baffle 7 can be effectively prevented from directly coming out of the second strip groove 13, resulting in good structural reliability.
[0031] A connecting seat 8 is fixed to the upper part of the headboard 11. The connecting seat 8 is located on the side of the head pillow 2 away from the main board 1. A vertical rod 9 is fixed to the upper part of the connecting seat 8. The vertical rod 9 is located on both sides of the head pillow 2. When the patient is lying flat for radiotherapy, the patient's hands can hold the vertical rod 9, thereby avoiding the patient's hands from blocking the radiotherapy site.
