[0001] This utility model relates to the field of medical device technology, specifically to a multi-purpose transfer cart for MRI examination. Background Technology

[0002] In modern medicine, MRI scans have become a routine procedure, and an increasing number of patients require them. Currently, some MRI rooms use specialized transfer carts or trolleys to assist patients entering the room for examinations, reducing patient discomfort and workload for medical staff. However, these carts and trolleys also have some drawbacks. For example, some carts only push the patient to the MRI equipment; medical staff then need to lift the patient onto the MRI examination bed. This is particularly challenging for disabled patients, as transferring them from the ward to the examination room and placing them on the examination bed is labor-intensive, making the process cumbersome and increasing the workload for medical staff. Utility Model Content

[0003] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a multi-purpose transfer trolley for MRI examination, which can switch between sitting and lying positions to facilitate the transfer of patients; at the same time, it can also move patients horizontally onto the MRI examination table for examination.

[0004] The technical solution adopted by this utility model is as follows: a multi-purpose transfer cart for MRI examination, including a lifting support frame, with a reclining assembly installed on the upper end of the lifting support frame; the reclining assembly includes a buttock plate fixed to the upper end of the support frame, a back support plate hinged to one end of the buttock plate and a leg support plate hinged to the other end, a pair of electric push rods hinged to the bottom of the buttock plate, the telescopic ends of the two electric push rods having hinged parts, the hinged parts being slidably connected to the back of the leg support plate and the back support plate respectively, so that the electric push rods can push the back support plate and the leg support plate to rotate clockwise or counterclockwise respectively; the buttock plate, the back support plate and the leg support plate are also provided with a conveyor belt assembly, the conveying direction of the conveyor belt assembly is arranged laterally along the reclining assembly, and the upper surface of the buttock plate, the back support plate and the leg support plate are also provided with a displacement plate, so that the conveyor belt assembly can drive the displacement plate to move along both sides of the reclining assembly.

[0005] In this technical solution, the multi-purpose transfer trolley has functions of reclining / sitting conversion and translation, facilitating the transfer of patients to the MRI examination area.

Detailed Implementation

[0019] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0020] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0021] like Figure 1 and Figure 2As shown, a specific embodiment of this utility model provides a multi-purpose transfer trolley for MRI examinations. This trolley has multiple functions, allowing for patient transfer and facilitating smooth loading and unloading from the MRI examination bed. Specifically, a lifting support frame 100 is included, with a reclining / sitting assembly mounted on its upper end. The reclining / sitting assembly includes a hip board 200 fixed to the upper end of the support frame. One end of the hip board 200 is hinged to a back support plate 300, and the other end is hinged to a leg support plate 400. A pair of electric push rods 500 are hinged to the bottom of the hip board 200, and the telescopic ends of the two electric push rods 500 are provided with hinged portions 510. The hinge portion 510 is slidably connected to the back of the leg support plate 400 and the back support plate, so that the electric push rod 500 can push the back support plate 300 and the leg support plate 400 to rotate clockwise or counterclockwise respectively; the buttock plate 200, the back support plate 300 and the leg support plate 400 are also provided with a conveyor belt assembly 600, the conveying direction of the conveyor belt assembly 600 is arranged laterally along the reclining assembly, and the upper surface of the buttock plate 200, the back support plate 300 and the leg support plate 400 are also provided with a displacement plate 700, so that the conveyor belt assembly 600 can drive the displacement plate 700 to move along both sides of the reclining assembly.

[0022] like Figure 1 and Figure 2 As shown, through the above-described configuration, the multi-purpose transfer trolley in this embodiment has functions for converting between lying and sitting positions and for lateral movement, facilitating the transfer of patients to the MRI examination area for examination. A pair of electric push rods 500 are hinged below the buttocks panel 200 of the trolley. These electric push rods 500 change the angle of the back support panel 300 and the leg support panel 400 by moving their telescopic ends, forming a back-raising and leg-bending structure; that is, when the telescopic end of the electric push rod 500, which is slidably hinged to the back support panel 300, extends, it pushes the back support panel and leg support panel 400. The support plate rotates upward to help the user sit up. When the telescopic end retracts, it pulls the back support plate and leg support plate downward to help the user lift their legs. This allows the device to be used as a wheelchair structure to transfer patients. When the back support plate 300 and leg support plate 400 rotate to the horizontal position, the device is used as a gurney. The patient is transferred to the MRI examination table by the conveyor belt assembly 600 on the buttocks plate 200, back support plate 300 and leg support plate 400, which drives the displacement plate 700 to move horizontally. This improves the efficiency of the examination.

[0023] like Figure 1 and Figure 2As shown, when this device is switched to wheelchair mode, it needs to support the patient's feet to prevent slippage. Therefore, in this embodiment, a foot support plate 800 is hinged to the end of the leg support plate 400 away from the hip plate 200. Pull rods 900 are rotatably connected to both sides of the hip plate 200, and the ends of the pull rods 900 are rotatably connected to both sides of the foot support plate 800. The upper surface of the foot support plate 800 is provided with an elastic support pad. Thus, the pull rods 900, the foot support plate, and the foot support plate 800 form a parallelogram mechanism. When the foot support plate rotates downwards driven by the electric push rod 500, the pull rods 900 pull the foot support plate 800 to rotate relative to the foot support plate, causing it to rotate upwards, thus providing a support structure for the patient's feet, helping the user support their feet and preventing slippage.

[0024] like Figure 1 and Figure 2 As shown, when this device is adjusted to a wheelchair structure for patient transfer, to improve the stability and comfort of the patient, this embodiment features symmetrically arranged armrests 1000 on both sides of the back support plate 300. Positioning portions 1100 are located below the armrests 1000 on both sides of the back support plate. When the armrests 1000 are rotated downwards to a horizontal position, their lower ends abut against the positioning portions 1100. This armrest structure can support the patient's hands, ensuring the disabled patient remains stable during transfer. Furthermore, this embodiment also features a push handle 1200 on the surface of the back support plate 300 opposite to the displacement plate 700. The push handle 1200 can be used to move the entire device.

[0025] As mentioned earlier, when this device is laid flat and used as a transfer bed, the patient needs to be transferred to the MRI examination bed by horizontal lateral movement of the displacement plate 700. In this embodiment, an array of positioning protrusions 610 are provided on the surface of the conveyor belt assembly 600 opposite to the displacement plate 700, and a positioning groove is provided on the lower surface of the displacement plate 700. In this way, the displacement plate 700 adapts to the positioning protrusions 610 and the positioning groove, so that the conveyor belt assembly 600 can drive the displacement plate 700 to move horizontally. At the same time, support rails 1300 are provided on both sides of the buttock plate 200, back support plate 300 and leg support plate 400 corresponding to the conveying direction of the conveyor belt assembly 600. The support rails 1300 are provided with support wheel sets that roll in contact with the lower surface of the displacement plate 700. In this way, the displacement plate 700 can be stably supported by the support rails 1300 to ensure that the displacement plate 700 can move horizontally stably, which facilitates the transfer of the patient to the examination bed. In addition, the upper surface of the displacement plate 700 is provided with an elastic support layer. It can improve the comfort of patients when lying down or sitting.

[0026] like Figure 1 and Figure 2As shown, in practical applications, the lifting support frame 100 of this device, used to support and change the height of the reclining / sitting component, includes a base 110. The lower end of the base 110 is equipped with a set of movable wheels 120, and the upper end of the base 110 is equipped with an electric lifting frame 130. The upper end of the electric lifting frame 130 is equipped with a fixed plate 140 connected to the buttocks plate 200. The movable wheels 120 on the base 110 enable the device to be movable, while the electric lifting frame 130 can be adjusted according to different heights of the MRI examination bed. The electric lifting frame 130 can adopt a scissor-type lifting structure, which is an existing technology and will not be described in detail here. A controller and power supplies for driving various electrical components can be installed on the base 110. The control buttons connected to the controller signal can be located on the outside of the base 110 for easy operation by medical personnel. During use, the height is adjusted first, then the reclining / sitting component is leveled, and finally, the component is moved horizontally. The entire process is stable and efficient, significantly reducing the workload of medical personnel.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
