Description

Technical Field

[0001] This utility model relates to the technical field of magnetic resonance imaging (MRI) auxiliary equipment, specifically to a magnetic resonance imaging (MRI) lifting and translation device. Background Technology

[0002] The diagnosis of craniocerebral diseases is an important medical and social concern today. Early diagnosis allows for intervention before full functional development, playing the greatest role among the currently limited rehabilitation treatment methods.

[0003] Magnetic resonance imaging (MRI) is a non-invasive medical imaging technique that utilizes the signals generated by the resonance of atomic nuclei within a magnetic field to reconstruct images, thus providing high-resolution images. The basic principle of MRI is that hydrogen nuclei in human tissue, within a static magnetic field, undergo magnetic resonance when excited by radio frequency pulses of a specific frequency. When the radio frequency pulse terminates, the hydrogen nuclei induce MR signals during relaxation. Through the processing of MR signals, including reception, spatial encoding, and image reconstruction, MR images are generated. MRI technology has advantages such as being non-invasive, radiation-free, and having high resolution. It can provide detailed images of internal human tissues, including soft tissues, bones, and blood vessels. In addition, MRI can provide quantitative analytical data, such as tissue metabolite concentrations and blood flow velocities.

[0004] Existing trolleys only have lifting and lowering functions, requiring manual lifting when moving patients. In the MRI scanning room, due to various reasons such as patient safety or comfort, it is very inconvenient for medical staff to arrange for patients with limited mobility to lie on the MRI scanning bed when transferring them from the trolley to the MRI scanning bed.

[0005] Therefore, developing and designing a lifting and translation device that can easily transfer patients to the MRI scanning bed and ensure smooth transport is an urgent problem to be solved at this stage. Utility Model Content

[0036] Please refer to Figures 1-5 This invention provides an embodiment of a magnetic resonance imaging (MRI) examination lifting and translation device, which includes a bed frame 1, a base 6 located below the bed frame 1, and a second lifting component between the base 6 and the bed frame 1. The second lifting component can drive the bed frame 1 to move in the vertical direction, thereby adjusting the height of the bed frame 1.

[0037] The upper surface of the bed frame 1 has a cavity 11; the first bed board 2 is embedded in the cavity 11; a first lifting assembly 3 is provided between the first bed board 2 and the cavity 11, and the first lifting assembly 3 can drive the first bed board 2 to move between a first height and a second height; at the first height, the upper surface of the first bed board 2 is located below the upper edge of the cavity 11; at the second height, the upper surface of the first bed board 2 is located above the upper edge of the cavity 11; a plurality of protruding ball bearings 4 are provided on the upper surface of the first bed board 2, and the second bed board 5 can be placed on the upper surface of the first bed board 2; when the first bed board 2 is at the first height, at least part of the second bed board 5 is embedded in the cavity 11, and the cavity 11 can position the second bed board 5; when the first bed board 2 is at the second height, the second bed board 5 can be conveniently moved relative to the first bed board 2 by rolling through the ball bearings 4.

[0038] It should be noted that the shape of the concave cavity 11 should match the first bed board 2 and the second bed board 5, and both are preferably plate-shaped. The concave cavity 11 can position the first bed board 2 and position the second bed board 5 when the first bed board 2 is at the second height. Furthermore, the bed frame 1, the first bed board 2 and the second bed board 5 should all be set horizontally so that the patient can lie comfortably on the second bed board 5 when the bed frame 1 or the first bed board 2 is raised or lowered.

[0039] For further details, please refer to Figures 1-3 Several pulleys 61 should be provided below the base 6 to facilitate the smooth and convenient movement of the entire utility model.

[0040] In this embodiment, please refer to Figure 3 The cavity 11 is connected to the lower surface of the bed frame 1, which can reduce the weight and production cost of the bed frame 1. At the same time, the cavity 11 should have a stepped surface 12 around its edge to facilitate the placement of the first lifting assembly 3. Specifically, the first lifting assembly 3 is preferably four, and the four first lifting assemblies 3 are respectively located at the four corners of the cavity 11, which can steadily drive the first bed board 2 to rise and fall. In other embodiments, the bottom surface of the cavity 11 can also be closed to facilitate the placement of the first lifting assembly 3 and the positioning of the first bed board 2. The number of the first lifting assembly 3 can also be other values, as long as it can smoothly drive the first bed board 2 to move between the first height and the second height.

[0041] Specifically, the first lifting component 3 is preferably a lead screw stepper motor.

[0042] For any further explanation, please refer to [link / reference]. Figure 1 The upper surface of one end of the second bed board 5 is provided with a raised pillow 51.

[0043] In this embodiment, please refer to Figure 2 The upper surface of the first bed board 2 is provided with a plurality of mounting grooves 21 that match the ball bearings 4 one by one. The mounting grooves 21 are hemispherical, and the ball bearings 4 are rotatably placed in the mounting grooves 21. When the second bed board 5 is placed on the first bed board 2 and moves, the ball bearings 4 cause the second bed board 5 and the first bed board 2 to have rolling friction, which can greatly reduce the friction. Specifically, the plurality of ball bearings 4 are preferably evenly distributed on the upper surface of the first bed board 2, which can stably support the sliding mode.

[0044] In this embodiment, please refer to Figures 1-3The second lifting assembly includes a telescopic part 71 and two scissor structures 72.

One end of the telescopic part 71 is hinged to the base 6, and the other end of the telescopic part 71 is hinged to the pivot 722. When the length of the telescopic part 71 changes, the angle between the two hinged forks 721 can be changed through the pivot 722. In other embodiments, the second lifting assembly can also be set as several vertically arranged cylinders or electric push rods, so as to stably drive the bed frame 1 to rise or fall.

[0045] For further details, please refer to Figures 1-3 The bed frame 1 and the base 6 are respectively provided with a slide rail 73 and a slider 74 that can move along the slide rail 73 at one end of the fork 721. One end of the fork 721 is hinged to the slider 74. When the fork 721 and the slider 74 move along the slide rail 73, the included angle of the two hinged forks 721 can change.

[0046] Specifically, the telescopic part 71 can be equipped with an electric push rod, a cylinder or a lead screw stepper motor, so as to be able to extend and retract stably and raise and lower the first bed board 2.

[0047] In this embodiment, please refer to Figure 4 and Figure 5 The present invention also includes a card plate 8, which has a plurality of protruding hooks 81 and a plurality of connecting holes 82; the side wall of the bed frame 1 has a plurality of threaded holes that match the connecting holes 82, and the side wall of the second bed board 5 has a plurality of positioning grooves 52; when the first bed board 2 is at the first height, the hooks 81 can be embedded into the positioning grooves 52, and are threadedly connected to the threaded holes by bolts passing through the connecting holes 82, thereby fixing the bed frame 1 and the second bed board 5 to prevent the second bed board 5 from sliding or accidentally rising and falling, thus preventing safety hazards and ensuring that the second bed board 5 moves smoothly with the bed frame 1.

[0048] It should be noted that the entire invention should be made of magnetically compatible non-magnetic materials to avoid affecting magnetic resonance imaging.
