Description

Technical Field

[0001] The present application belongs to the field of medical device technology, and more specifically, relates to a bed board for medical imaging equipment. Background Art

[0002] Currently, medical imaging scans are typically performed while the patient lies on a bed, which is primarily used to support and stably move the patient into the scanning space of the medical imaging equipment. Current bedplates primarily operate in a cantilevered configuration, requiring stable and reliable load-bearing capacity and rigidity to ensure high-quality scanned images. To improve the load-bearing capacity and rigidity of bedplates, most currently utilize a sandwich structure. This structure offers high load-bearing capacity and rigidity, but the sandwich structure has low radiation transmittance, resulting in significant radiation attenuation and, in turn, reduced scanned image quality. Therefore, current bedplates struggle to simultaneously achieve high rigidity and high scan image quality. Summary of the Invention

[0003] The purpose of the present application is to provide a bed board for medical imaging equipment to solve the technical problem in the prior art that it is difficult for the bed board to simultaneously achieve high rigidity and obtain high scan image quality.

[0004] To achieve the above objectives, the technical solution adopted in this application is:

[0005] A bed board for medical imaging equipment, comprising:

[0006] A scanning plate, which can enter the scanning space of the medical imaging device, has an arc-shaped structure with a concave middle portion along the width direction, and the ratio of the height difference of the scanning plate itself to the width of the scanning plate is greater than 1 / 10.

[0007] By setting the scanning plate as an arc-shaped structure with a concave middle part, and the ratio of the height difference of the scanning plate itself to the width of the scanning plate is greater than 1 / 10, this design can improve the rigidity of the scanning plate without increasing the plate thickness or setting ribs, reduce the deformation of the scanning plate in the length direction, and enable the scanning plate to adopt a single-layer structure, thereby achieving reliable support for the patient and reducing the risk of the patient overturning and falling, and improving the transmittance of the scanning rays to reduce the negative impact of the scanning plate on the scanned image, thereby helping to improve the accuracy of the scanned image. In addition, this design can allow the scanning plate to be thinner under the same load requirements, thereby helping to reduce the weight and manufacturing cost of the scanning plate.

[0008] As an implementation manner, the ratio of the height difference of the scanning plate itself to the width of the scanning plate is between 1 / 7 and 1 / 5.

[0009] As an embodiment, the curvature of the edge region of the scanning plate along the width direction is greater than the curvature of the central region of the scanning plate along the width direction.

[0010] By configuring the scanning plate such that the curvature of the edge region is greater than the curvature of the central region, the central region of the scanning plate becomes relatively flatter, thereby facilitating improvement of patient comfort.

[0011] As an embodiment, the bed board also includes a mounting plate, which is used to connect to the mobile platform of the medical imaging equipment. The scanning plate is fixedly arranged at one end of the mounting plate, and the thickness of the scanning plate decreases in the direction away from the mounting plate.

[0012] During the use of the bed plate, the movable platform can drive the bed plate to move horizontally along the length direction of the bed plate so that the scanning plate enters or leaves the scanning space. One end of the scanning plate is connected to the mounting plate, and the other end of the scanning plate is suspended. Since the end of the scanning plate away from the mounting plate is suspended, the closer the scanning plate is to the mounting plate, the greater the torque it is subjected to. Therefore, by setting the thickness of the scanning plate to become smaller in the direction away from the mounting plate, the thickness of the scanning plate close to the mounting plate can be relatively larger, and the thickness of the scanning plate away from the mounting plate can be relatively smaller. This design can not only ensure that the scanning plate close to the mounting plate has sufficient rigidity, but also avoid excessive redundancy of the thickness of the scanning plate away from the mounting plate, thereby helping to make the scanning plate lighter and have lower manufacturing costs.

[0013] As an embodiment, the thickness of the edge region of the scanning plate along the width direction is smaller than the thickness of the central region of the scanning plate along the width direction.

[0014] In actual application, the load that the central area of ​​the scanning plate needs to bear is greater than that of the edge area. Therefore, by setting the plate thickness of the scanning plate in the edge area to be smaller than that in the central area, it can not only help the central area to reliably bear the load, but also reduce the thickness redundancy of the edge area, which helps the scanning plate to be better lightweight.

[0015] As an embodiment, the bed board further includes a flange, the flange is fixedly arranged on a side of the scanning board, and the flange extends along the length direction of the scanning board.

[0016] By arranging the flange extending along the length direction of the scanning plate on the side of the scanning plate, the rigidity of the scanning plate can be improved, and the deformation of the scanning plate in the length direction can be reduced, thereby helping to improve the bearing reliability of the bed board on the patient.

[0017] As an embodiment, the flange is a curved structure.

[0018] By setting the flange as a curved structure, it is possible to avoid the flange from forming a folded corner, thereby helping to reduce the negative impact of the flange on the scanned image and helping to improve the accuracy of the scanned image.

[0019] As an embodiment, the flange includes a fixedly connected connecting portion and a bent portion, one end of the connecting portion is connected to the edge of the scanning plate, and the other end of the connecting portion extends upward and is connected to the bent portion.

[0020] By providing the connecting portion extending upward from the edge of the scanning plate, the overall height difference between the scanning plate and the flange can be increased. If the flange is regarded as a part of the scanning plate, it is equivalent to magnifying the ratio of the height difference of the scanning plate itself to the width of the scanning plate. Based on this design, under the premise that the width of the scanning plate remains unchanged and the load demand remains unchanged, the height difference of the scanning plate itself can be reduced, thereby making the arc structure of the scanning plate smoother, thereby providing the patient with a more comfortable bearing experience.

[0021] As an embodiment, a first reinforcing rib is provided at one end of the scanning plate away from the mounting plate, and the first reinforcing rib extends along the width direction of the scanning plate; and / or a second reinforcing rib is provided at one end of the mounting plate away from the scanning plate, and the second reinforcing rib extends along the width direction of the mounting plate.

[0022] Providing the first reinforcing rib or the second reinforcing rib extending in the width direction can help to increase the rigidity of the bed board in the width direction, thereby reducing the deformation of the bed board in the width direction.

[0023] As an embodiment, the bed board further includes a reinforcement structure, and the reinforcement structure is arranged at the bottom of the mounting plate.

[0024] By arranging the reinforcing structure at the bottom of the mounting plate, the strength of the mounting plate can be improved, thereby improving the reliability of the mounting plate in supporting the scanning plate and the patient.

[0025] The beneficial effects of the bed board for medical imaging equipment provided by this application are:

[0026] By setting the scanning plate as an arc-shaped structure with a concave middle part, and the ratio of the height difference of the scanning plate itself to the width of the scanning plate is greater than 1 / 10, this design can improve the rigidity of the scanning plate without increasing the plate thickness or setting ribs, reduce the deformation of the scanning plate in the length direction, and enable the scanning plate to adopt a single-layer structure, thereby achieving reliable support for the patient and reducing the risk of the patient overturning and falling, and improving the transmittance of the scanning rays to reduce the negative impact of the scanning plate on the scanned image, thereby helping to improve the accuracy of the scanned image. In addition, this design can allow the scanning plate to be thinner under the same load requirements, thereby helping to reduce the weight and manufacturing cost of the scanning plate.

It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0049] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0050] The embodiment of the present application provides a bed board 100 for medical imaging equipment, such as Figures 1 to 3 As shown, the bed plate 100 for medical imaging equipment includes a scanning plate 2, which can enter the scanning space 300 of the medical imaging equipment. The scanning plate 2 is an arc-shaped structure with a concave center along the width direction. The ratio of the height difference Y of the scanning plate 2 to the width X of the scanning plate 2 is greater than 1 / 10. Specifically, the height difference refers to the difference between the highest point and the lowest point of the scanning plate in the height direction when the scanning plate is placed horizontally, such as Figure 3 Label Y shown.

[0051] By setting the scanning plate 2 as an arc-shaped structure with a concave middle part, and the ratio of the height difference Y of the scanning plate 2 itself to the width X of the scanning plate 2 is greater than 1 / 10, this design can improve the rigidity of the scanning plate 2 without increasing the plate thickness or setting ribs, reduce the deformation of the scanning plate 2 in the longitudinal direction, and enable the scanning plate 2 to adopt a single-layer structure, thereby achieving reliable support for the patient and reducing the risk of the patient overturning and falling, and improving the transmittance of the scanning rays to reduce the negative impact of the scanning plate 2 on the scanned image, thereby helping to improve the accuracy of the scanned image. In addition, this design can allow the scanning plate 2 to be thinner under the same load requirements, thereby helping to reduce the weight and manufacturing cost of the scanning plate 2.

[0052] In one embodiment, the ratio of the height difference Y of the scanning plate 2 to the width X of the scanning plate 2 is between 1 / 7 and 1 / 5.

[0053] In one embodiment, if Figure 4 As shown, the curvature of the edge region 21 of the scanning plate 2 along the width direction is greater than the curvature of the central region 22 of the scanning plate 2 along the width direction. By setting the curvature of the edge region 21 of the scanning plate 2 to be greater than the curvature of the central region 22, the central region 22 of the scanning plate 2 becomes relatively flatter, thereby improving patient comfort.

[0054] Of course, in other embodiments, it may also be designed that the curvatures of different regions of the scanning plate 2 along the width direction are the same.

[0055] In one embodiment, the bed board 100 further includes a mounting plate 1, which is used to connect to the mobile platform 200 of the medical imaging device. The scanning plate 2 is fixedly arranged at one end of the mounting plate 1, and the thickness of the scanning plate 2 decreases in the direction away from the mounting plate 1. During the use of the bed board 100, the mobile platform 200 can drive the bed board 100 to move horizontally along the length direction of the bed board 100 so that the scanning plate 2 enters or leaves the scanning space 300. One end of the scanning plate 2 is connected to the mounting plate 1, and the other end of the scanning plate 2 is suspended. Since the end of the scanning plate 2 away from the mounting plate 1 is suspended, the closer the scanning plate 2 is to the mounting plate 1, the greater the torque it bears. Therefore, by setting the thickness of the scanning plate 2 to become smaller in the direction away from the mounting plate 1, the thickness of the scanning plate 2 close to the mounting plate 1 can be relatively larger, and the thickness of the scanning plate 2 away from the mounting plate 1 can be relatively smaller. This design can not only ensure that the scanning plate 2 close to the mounting plate 1 has sufficient rigidity, but also avoid excessive redundancy of the thickness of the scanning plate 2 away from the mounting plate 1, thereby helping to make the scanning plate 2 lighter and the manufacturing cost lower.

[0056] Of course, in other embodiments, the scanning plate 2 may also be a structure with a uniform thickness along the entire length direction.

[0057] In one embodiment, the mounting plate 1 and the scanning plate 2 are integrally formed. Of course, in other embodiments, the mounting plate 1 and the scanning plate 2 can also be independently processed structures and fixedly connected to each other.

[0058] In one embodiment, the thickness of the mounting plate 1 is greater than the thickness of the scanning plate 2. Furthermore, the thickness of the mounting plate 1 is more than 1.5 times the thickness of the scanning plate 2.

[0059] In one embodiment, if Figure 5 As shown, the plate thickness of the edge region 21 of the scanning plate 2 along the width direction is smaller than the plate thickness of the central region 22 of the scanning plate 2 along the width direction.

[0060] In actual application, the load that the central area 22 of the scanning plate 2 needs to bear is greater than that of the edge area 21. Therefore, by setting the plate thickness of the scanning plate 2 so that the edge area 21 is smaller than the central area 22, it can not only help the central area 22 to reliably bear the load, but also reduce the plate thickness redundancy of the edge area 21, which helps to better achieve lightweighting of the scanning plate 2.

[0061] In one embodiment, the thickness of the scanning plate 2 decreases gradually from the center to the edge along the width direction.

[0062] In one embodiment, if Figure 2 、 Figure 6 and Figure 7As shown, the bed plate 100 further includes a flange 3, which is fixedly disposed on the side of the scanning plate 2 and extends along the length of the scanning plate 2. In a specific implementation, there are two flanges 3, which are fixedly disposed on both sides of the scanning plate 2.

[0063] By providing flanges 3 on both sides of the scanning plate 2, extending along the length of the scanning plate 2, the rigidity of the scanning plate 2 can be increased, the deformation of the scanning plate 2 in the longitudinal direction can be reduced, and the patient-bearing reliability of the bed plate 100 can be improved. Of course, in other embodiments, if the scanning plate 2 has sufficient rigidity, the flanges 3 may not be provided. For example, the scanning plate 2 can be provided with sufficient rigidity by increasing the ratio of the height difference of the scanning plate 2 to the width of the scanning plate 2 or by increasing the thickness of the scanning plate 2.

[0064] In one embodiment, the flanges 3 on both sides of the scanning plate 2 are symmetrically arranged to make the structure of the scanning plate 2 more stable and balanced.

[0065] In one embodiment, if Figure 6 and Figure 7 As shown, the flange 3 is a curved surface structure. In a specific implementation, the flange 3 can be a smooth curved surface structure. By setting the flange 3 as a curved surface structure, the flange 3 can be prevented from forming corners, thereby helping to reduce the negative impact of the flange 3 on the scanned image and improve the accuracy of the scanned image.

[0066] In one embodiment, if Figure 9 As shown, the flange 3 includes a fixedly connected connecting portion 31 and a bent portion 32 , one end of the connecting portion 31 is connected to the edge of the scanning plate 2 , and the other end of the connecting portion 31 extends upward and is connected to the bent portion 32 .

[0067] By providing a connecting portion 31 extending upward from the edge of the scanning plate 2, the overall height difference between the scanning plate 2 and the flange 3 can be increased. If the flange 3 is regarded as a part of the scanning plate 2, it is equivalent to magnifying the ratio of the height difference of the scanning plate 2 itself to the width of the scanning plate 2. Based on this design, under the premise that the width of the scanning plate 2 remains unchanged and the load demand remains unchanged, the height difference of the scanning plate 2 itself can be reduced, thereby making the arc structure of the scanning plate 2 smoother, thereby providing the patient with a more comfortable bearing experience.

[0068] In one embodiment, if Figure 9 As shown, the connecting portion 31 gradually tilts from bottom to top toward the outside of the scanning plate 2. This outward tilted structure allows the patient to enter the space above the scanning plate 2 more easily and reduces the risk of the patient bumping into something.

[0069] In one embodiment, if Figure 9As shown, the curved portion 32 is bent toward the outside of the scanning plate 2. This design can prevent the curved portion 32 from encroaching on the space above the scanning plate 2 and can reduce the risk of the patient being bumped. In a specific implementation, the curved portion 32 can be a semicircular structure.

[0070] Of course, in other embodiments, the connecting portion 31 may also extend downward from the edge of the scanning plate 2 and connect to the bent portion 32 . This design can also improve the rigidity of the scanning plate 2 in the length direction.

[0071] In one embodiment, if Figure 2 and Figure 8 As shown, the flange 3 extends to the mounting plate 1 and is fixedly connected to the mounting plate 1. By extending the flange 3 to the mounting plate 1, the flange 3 can run through the entire length of the bed board 100, thereby helping to improve the overall rigidity of the bed board 100.

[0072] In one embodiment, if Figure 2 and Figure 7 As shown, a first reinforcing rib 4 is provided at one end of the scanning plate 2 away from the mounting plate 1, and the first reinforcing rib 4 extends along the width direction of the scanning plate 2; Figure 2 and Figure 6 As shown, a second reinforcing rib 5 is provided at one end of the mounting plate 1 away from the scanning plate 2 , and the second reinforcing rib 5 extends along the width direction of the mounting plate 1 .

[0073] Providing the first reinforcing ribs 4 or the second reinforcing ribs 5 extending in the width direction can help to improve the rigidity of the bed board 100 in the width direction, thereby reducing the deformation of the bed board 100 in the width direction.

[0074] In one embodiment, the first reinforcing rib 4 and the second reinforcing rib 5 are straight plate structures or curved plate structures bent outward.

[0075] In one embodiment, if Figure 2 、 Figure 6 and Figure 7 As shown, the two ends of the first reinforcing rib 4 are respectively connected to the flange 3, and the two ends of the second reinforcing rib 5 are respectively connected to the flange 3, so that the first reinforcing rib 4, the second reinforcing rib 5 and the flange 3 form a closed reinforcing structure 6 in the horizontal direction, which helps to improve the stiffness of the bed board 100 in the length and width directions and reduce the overall deformation of the bed board 100.

[0076] In one embodiment, if Figure 2 As shown, the first reinforcing rib 4 protrudes upward from the top of the scanning plate 2. Of course, in other embodiments, it can also be designed that the first reinforcing rib 4 protrudes downward from the bottom of the scanning plate 2.

[0077] In one embodiment, if Figure 2As shown, the second reinforcing rib 5 protrudes upward from the top of the mounting plate 1 . Of course, in other embodiments, it can also be designed that the second reinforcing rib 5 protrudes downward from the bottom of the mounting plate 1 .

[0078] In one embodiment, if Figure 2 、 Figures 6 to 8 As shown, the bed plate 100 further includes a reinforcing structure 6, which is provided at the bottom of the mounting plate 1. By providing the reinforcing structure 6 at the bottom of the mounting plate 1, the strength of the mounting plate 1 can be improved, thereby improving the reliability of the mounting plate 1 in supporting the scanning plate 2 and the patient.

[0079] In one embodiment, the reinforcement structure 6 is integrally formed with the mounting plate 1 . Of course, in other embodiments, the reinforcement structure 6 may also be an independently processed structure and fixedly connected to the mounting plate 1 .

[0080] In one embodiment, if Figure 8 As shown, the reinforcement structure 6 includes two or more reinforcement rods extending along the length of the mounting plate 1 and spaced apart along the width of the mounting plate 1 at the bottom. Furthermore, the cross-section of the reinforcement rods is an inverted trapezoid. Of course, in other embodiments, the reinforcement structure 6 may also be a reinforcement plate fixed to the bottom of the mounting plate 1.

[0081] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
