Description

Technical Field

[0001] This utility model relates to the field of lateral body support technology, specifically to a CT magnetic resonance lateral body support frame. Background Technology

[0002] During CT or MRI scans, patients are typically examined in various positions, with the lateral position being the most common. However, due to the relatively long examination time, the patient's body is prone to movement, which can significantly affect the examination results. Therefore, it is necessary to provide auxiliary fixation for the patient's lateral position during the examination.

[0003] Patent document CN222032428U discloses a CT magnetic resonance imaging (MRI) lateral positioning auxiliary frame, including a base plate, a flat plate, an adjustable inclined plate, a rubber protective pad, a side blocking mechanism, bandages, connectors, and an angle adjustment mechanism. The base plate has a flat plate and an adjustable inclined plate on its upper side. Multiple legs fixed to the bottom of the flat plate are also fixed to the base plate. A rotating shaft is fixed to the right end of the adjustable inclined plate, passing through the left end of the flat plate and rotatably connected to it. A side blocking mechanism is installed on the flat plate, and multiple bandages are mounted on the side blocking mechanism. Multiple connectors for connecting the bandages are fixed to the adjustable inclined plate. An angle adjustment mechanism for adjusting the angle of the adjustable inclined plate is installed on the base plate. This utility model provides convenient fixation for the human body and easy adjustment of the tilt angle, facilitating lateral positioning detection.

[0004] However, the above-mentioned existing technologies have some problems and shortcomings in practical applications: they are only convenient for the human body to tilt to one side, but not convenient for tilting to the other side, making them relatively inconvenient to use. Moreover, they require bandages to be tied when fixing the human body, which is still quite cumbersome, so they need to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a CT magnetic resonance imaging (MRI) lateral support frame to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a CT magnetic resonance imaging lateral support frame, comprising a base and a supporting reclining board. A first upright and a second upright are fixedly connected to the left and right ends of the upper surface of the base, respectively. A first shaft and a second shaft are rotatably connected to the upper ends of the first and second uprights, respectively. The opposite ends of the first and second shafts are jointly fixedly connected to the lower surface of the supporting reclining board. A transmission mechanism for controlling the forward or reverse rotation of the first shaft is connected to the end of the first shaft away from the second shaft. The surface of the supporting reclining board has at least three through slots equidistantly distributed along its length. Two opposing limiting arms are connected to the inner side of each through slot. The two limiting arms are bent to opposite sides, and the distance between them can be adjusted by an adjustment mechanism. A head-supporting pillow for facilitating patient head support is fixedly connected to the left side of the upper surface of the supporting reclining board.

[0007] Furthermore, the adjustment mechanism includes a limiting frame with an opening at the upper end, a bidirectional lead screw rotatably connected within the limiting frame, and movable end seats threadedly connected to both ends of the bidirectional lead screw. The upper end of the limiting frame is fixedly connected to the lower surface of the supporting plate, and its opening is opposite to and extends in the same direction as the through groove. One end of the bidirectional lead screw extends through the limiting frame and is connected to an adjustment knob. The distance between the two movable end seats is controlled by rotating the bidirectional lead screw through the adjustment knob. The limiting arm is detachably mounted on the movable end seat.

[0008] Furthermore, the upper end of the movable end seat is provided with a slot, and the side wall of the movable end seat is provided with a positioning hole that communicates with the slot. The lower end of the limiting arm is inserted into the slot, and the outer side of the lower end of the limiting arm is elastically connected with a positioning post that cooperates with the positioning hole.

[0009] Furthermore, the limiting arm has an internal cavity, and a guide wheel is rotatably mounted on the inner wall of the cavity. A pull rod is slidably mounted on the upper end of the limiting arm, extending into the cavity. A support ring is fixedly connected to the bottom wall of the cavity. One end of the support ring is connected to a positioning post via a spring. The end of the positioning post located inside the cavity is connected to a pull rope. The pull rope passes through the support ring, wraps around the guide wheel, and is fixedly connected to the lower end of the pull rod, forming a linkage traction structure.

[0010] Furthermore, the transmission mechanism is a worm gear transmission structure, including a turbine fixedly connected to the first shaft and a worm gear meshing with the turbine gear, the lower end of the worm gear being connected to a driving component.

[0011] Furthermore, a shielding cover is provided on the outside of the transmission mechanism.

[0012] Furthermore, a bending support plate is connected to the contact side of the limiting arm with the human body, and a soft pad layer is fixedly connected to the inner side of the bending support plate. The soft pad layer is a rubber layer or a sponge layer.

[0013] The above technical solution has the following advantages compared with the existing technology: it is suitable for clamping and fixing the body of patients of different body types, provides convenience for the patient to turn to the side, does not require binding straps, and is easy to use.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0018] In view of the problems existing in the prior art, the present invention provides a CT magnetic resonance imaging lateral support frame, which will be described in detail below with reference to the accompanying drawings. Example

[0019] See Figures 1-4 As shown, the technical solution adopted in this specific embodiment is: a CT magnetic resonance imaging (MRI) lateral support frame, including a base 1 and a supporting reclining plate 2. A first upright 11 and a second upright 12 are fixedly connected to the left and right ends of the upper surface of the base 1, respectively. A first shaft 111 and a second shaft 121 are rotatably connected to the upper ends of the first upright 11 and the second upright 12, respectively. The opposite ends of the first shaft 111 and the second shaft 121 are jointly fixedly connected to the lower surface of the supporting reclining plate 2. A transmission mechanism 5 for controlling the forward or reverse rotation of the first shaft 111 is connected to the end of the first shaft 111 away from the second shaft 121. Alternatively, the transmission mechanism 5 can also be mounted on the second shaft 121.

[0020] It should be specifically noted that the transmission mechanism 5 is a turbine 51 and worm 52 transmission structure, specifically including a turbine 51 fixedly connected to the first shaft, a worm 52 meshing with the turbine 51, and a driving member 53 fixedly connected to the lower end of the worm 52.

[0021] The driving component 53 is either a servo motor or a drive handwheel. When the driving component 53 is a servo motor, after the servo motor is fixedly connected to the mounting bracket 55, its output end is connected to the turbine 51. The servo motor is selected based on a model with high-efficiency electromagnetic shielding to effectively avoid electromagnetic interference to the equipment. When the driving component 53 is a servo motor, a shielding cover 54 can also be provided outside the transmission mechanism 5. When the driving component 53 is a drive handwheel, the transmission mechanism 5 should have a self-locking function.

[0022] It should be specifically noted that the surface of the support reclining board 2 is provided with at least three through slots 22 that are equidistantly distributed along its length. The inner side of each through slot 22 is connected to two opposing limiting arms 3. The two limiting arms 3 are bent to opposite sides, and the distance between them can be adjusted by the adjustment mechanism 4. A head-limiting pillow 21 for supporting the patient's head is fixedly connected to the left side of the upper surface of the support reclining board 2.

[0023] A soft padding layer 37 is provided on the side of the limiting arm 3 that contacts the human body. The soft padding layer 37 can be a rubber layer or a sponge layer.

[0024] The distance between the two relative limiting arms 3 can be adjusted by the adjustment mechanism 4 to fix the patient's body. The tilt of the support bed 2 can be adjusted by the transmission mechanism 5, which facilitates the patient to turn to the side.

[0025] It should be specifically noted that the adjustment mechanism 4 includes a limiting frame 41 with an opening 411 at the upper end, a bidirectional lead screw 42 rotatably connected within the limiting frame 41, and movable end seats 43 threadedly connected to both ends of the bidirectional lead screw 42. The upper end of the limiting frame 41 is fixedly connected to the lower surface of the support plate 2, and its opening 411 is opposite to and extends in the same direction as the through groove 22. One end of the bidirectional lead screw 42 extends through the limiting frame 41 and is connected to an adjustment knob 44. The distance between the two movable end seats 43 is controlled by rotating the bidirectional lead screw 42 through the adjustment knob 44. The limiting arm 3 is detachably mounted on the movable end seat 43.

[0026] Adjusting the knob 44 can drive the bidirectional lead screw 42 to rotate. The rotation of the bidirectional lead screw 42 can drive the two movable end seats 43 to move closer together or separate from each other. By moving the two movable end seats 43 closer together, the two limiting arms 3 can be moved closer together, thereby clamping and fixing the patient's body and adapting to patients of different body types. Example

[0027] See Figures 3-4 As shown, the difference between this embodiment and embodiment 1 is that a slot 431 is provided at the upper end of the movable end seat 43, and a positioning hole 432 communicating with the slot 431 is provided through the side wall of the movable end seat 43. The lower end of the limiting arm 3 is inserted into the slot 431, and a positioning post 32 that cooperates with the positioning hole 432 is elastically connected to the outer side of the lower end of the limiting arm 3.

[0028] It should be specifically noted that the limiting arm 3 has a cavity 33 inside, and a guide wheel 331 is rotatably mounted on the inner wall of the cavity 33. A pull rod 34 is slidably mounted on the upper end of the limiting arm 3, and the pull rod 34 extends into the cavity 33. A support ring 332 is fixedly connected to the bottom wall of the cavity 33. One end of the support ring 332 is connected to a positioning post 32 through a spring 35. The end of the positioning post 32 located in the cavity 33 is connected to a pull rope 36. The pull rope 36 passes through the support ring 332, wraps around the guide wheel 331, and is fixedly connected to the lower end of the pull rod 34 to form a linkage traction structure. Pulling the lever 34 applies tension to one end of the pull rope 36. Guided by the guide wheel 331, the pull rope 36 applies tension to the positioning post 32, causing the positioning post 32 to retract into the cavity 33 of the limiting arm 3. At this time, the positioning post 32 separates from the positioning hole 432, thus facilitating the disassembly and installation of the limiting arm 3. Without external force, the spring 35 applies elastic force to the positioning post 32, causing it to extend outward, thus ensuring the stability of the positioning post 32 after it engages with the positioning hole 432.

[0029] The entire device is made of non-ferromagnetic materials such as plastic or titanium alloy to avoid interfering with the test results.

[0030] Working principle: In use, first pull the lever 34, which in turn pulls the rope 36, and then the rope 36 pulls the positioning post 32, causing the positioning post 32 to disengage from the positioning hole 432. Then, push the limiting arm 3 upward to pull it out of the slot 431, thus disassembling the limiting arm 3. Next, have the patient lie flat on the support bed 2 with their head placed on the head limiting pillow 21. Once the patient is properly positioned, insert the lower end of the limiting arm 3 into the slot 431, and reinsert the positioning post 32 into the positioning hole 432 to fix the limiting arm 3. By rotating the adjustment knob 44, the bidirectional lead screw 42 is rotated, which in turn causes the two movable end seats 43 to move closer together, thus clamping and fixing the patient's body with the limiting arm 3. Once the patient's body is fixed, the inclination of the support bed 2 is adjusted using the transmission mechanism 5.
