Description

Technical Field

[0001] This utility model relates to the field of nuclear magnetic resonance imaging (MRI) examination equipment technology, specifically to a bed board that automatically adjusts body position at multiple angles. Background Technology

[0002] Magnetic resonance imaging (MRI) is a diagnostic method that uses radio electromagnetic wave signals. Based on the different reactions of the human body to these signals, the results are processed by complex computer calculations and can be used for clinical diagnosis. It does not have any adverse effects on the human body.

[0003] Magnetic resonance imaging (MRI) equipment typically consists of a large cylindrical body with an internal scanning cavity containing a sliding scanning bed. The scanning bed supports the patient and can move vertically up and down and horizontally. When the patient lies on the scanning bed, the bed automatically moves the patient in and out of the scanning cavity. During the scan, the area being examined needs to be correctly positioned on the scanning plane. The stability, safety, and reliability of the scanning bed directly affect the patient's safety and the imaging results.

[0004] Currently, scanning beds are generally longer than 2.1 meters and lack positioning devices or markers. When patients lie on the bed, they often cannot lie in the correct position and need to be adjusted according to the instructions of medical staff to reach the most suitable position. However, for patients with limited mobility, any movement on the scanning bed is particularly difficult and may cause secondary injury to the patient's body. It is also difficult to adjust the area to be examined to the correct position, which wastes manpower and delays the examination time.

[0005] Therefore, developing a multi-angle automatic position adjustment plate that can avoid frequent adjustments to the examination position and help patients with limited mobility to smoothly complete the examination is an urgent problem to be solved at this stage. Utility Model Content

[0006] To address the problems existing in the prior art, this utility model provides a bed board with multi-angle automatic position adjustment. When the patient lies on the soft pad on the board, the frame and the mechanical arm on the board swing, and the shape of the corresponding area of ​​the soft pad can be adjusted through the partitions on the board, thereby finely adjusting the patient's position on the soft pad and helping the patient stay still during the examination, reducing patient movement, shortening the examination time, and reducing secondary injury to the patient.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0018] As a preferred technical solution, a base is provided at the end where the robotic arm connects to the frame.

[0019] As a preferred technical solution, the frame is provided with a plurality of connection holes corresponding to the base, and the base is fixedly connected to the frame by bolts.

[0020] As a preferred technical solution, the frame is connected to a moving component that drives its horizontal movement and a lifting component that drives its vertical movement; the moving component can drive the frame to move between a first position and a second position, wherein in the first position the plate is located inside the scanning cavity; and in the second position the plate is located outside the scanning cavity.

[0021] As a preferred technical solution, the bottom surface of the plate is provided with a slot, and the upper edge of the frame is embedded in the slot.

[0022] The beneficial effects of this utility model are as follows:

[0023] The plate is stably supported by several robotic arms on the frame.

[0029] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0030] Please refer to Figures 1-4 This invention provides an embodiment of a multi-angle automatically adjustable bed board, comprising a board body 1 with several partitions 11. Each partition 11 is elastically deformable; when subjected to force, it deforms relative to the board body 1. A soft pad 2 is placed on the board body 1 to increase its softness and ensure comfort. The shape of the area corresponding to each partition 11 can change with the partition 11. A frame 3 is located below the board body 1, and several robotic arms 4 are installed within it. One end of each robotic arm 4 is fixedly connected to the frame 3, and the other end abuts against the bottom surface of each partition 11. While supporting the board body 1, when a robotic arm 4 swings slightly in the vertical direction, it can adjust the shape of the corresponding area of ​​the soft pad 2 through the bed partitions 11. Furthermore, the board body 1, soft pad 2, and frame 3 should all be made of non-magnetic materials to avoid interfering with MRI imaging.

[0031] It should be noted that the entire plate 1 can be made of the same material as partition 11, and partition 11 can be made of materials with high comfort such as soft padding; the robotic arm 4 should be made of magnetic resonance compatible materials, such as plastic, carbon fiber, etc., which will not affect magnetic resonance imaging.

[0032] Specifically, a slot is preferably provided on the bottom surface of the plate 1, and the upper edge of the frame 3 is embedded in the slot to effectively position the plate 1.

[0033] In this embodiment, please refer to Figure 2 There are nine partitions 11. Specifically, one of the nine partitions 11 corresponds to the patient's head, two correspond to the patient's upper limbs, two correspond to the patient's torso, and four correspond to the patient's lower limbs. By deforming a certain partition 11, the position of the corresponding part of the patient can be precisely adjusted. In other embodiments, the number of partitions 11 can also be set to other values ​​or distributed in other forms, so as to enable precise adjustment of the position of various parts of the patient's body.

[0034] For further details, please refer to Figure 3 The robotic arm 4 should correspond one-to-one with the partition 11. Each robotic arm 4 can adjust the shape of the corresponding partition 11 by swinging vertically. In other embodiments, multiple robotic arms 4 can also be set at each partition 11, so as to be able to stably drive the partition 11 to deform.

[0035] In this embodiment, please refer to Figure 3 and Figure 4 A support plate 41 is provided at the end of the robotic arm 4 that abuts against the partition 11. The support plate 41 is set horizontally and can increase the contact area with the bottom of the partition 11, ensuring that the robotic arm 4 can stably drive the partition 11 to deform.

[0036] Specifically, the support plate 41 is preferably connected to the robotic arm 4 via a joint bearing to ensure that the support plate 41 remains horizontal while moving up and down with the robotic arm 4.

[0037] In this embodiment, please refer to Figure 3 and Figure 4 The robotic arm 4 includes three sub-arms 42 connected in sequence. The three sub-arms 42 rotate around the first axis, the second axis and the third axis respectively. The first axis, the second axis and the third axis are perpendicular to each other. The effective rotation of the three sub-arms 42 can stably drive the support plate 41 to swing in the vertical direction.

[0038] For further details, please refer to Figure 4 The robotic arm 4 is connected to the frame 3 at one end with a base 43. Correspondingly, the frame 3 is provided with several connecting holes 31 at the base 43. The base 43 is fixedly connected to the frame 3 by bolts that match the connecting holes 31.

[0039] It should be noted that the frame 3 is connected to a moving component that drives its horizontal movement and a lifting component that drives its vertical movement; specifically, the moving component can drive the frame 3 to move between a first position and a second position. In the first position, the plate 1 is located inside the scanning cavity; in the second position, the plate 1 is located outside the scanning cavity. Through the moving component and the lifting component, the plate 1 can automatically enter and exit the scanning cavity, and the plate 1 can be adjusted in the height direction to ensure that the patient's examined area is accurately located on the scanning plane.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
