Abstract
Description
Technical Field
[0001] This invention relates to the field of medical auxiliary device technology, specifically to a multi-angle adjustable neonatal radiation protection device. Background Technology
[0002] An upright abdominal radiograph is a type of X-ray examination, mainly used to assess acute abdominal conditions, intestinal obstruction, gastrointestinal perforation, and other emergencies. The patient is in a standing position when the radiograph is taken. The principle of gas and liquid separation is used to show abnormalities in the abdominal cavity. When performing a three-dimensional abdominal radiograph on a newborn, medical staff or relatives need to lift the newborn and straighten their position so that their head and back are in contact with the chest X-ray frame, which affects the operation of the upright abdominal radiograph by medical staff.
[0003] The existing invention patent with publication number CN117338320B, concerning a protective device for neonatal radiation and its control method, comprises: a support frame having perpendicular vertical and horizontal directions and a first direction, with wheels at the lower part of the support frame; a support plate located above the support frame, with a rotating shaft extending along the first direction at the lower part of the support plate, the rotating shaft being rotatably connected to the support frame; a rotation drive assembly located on the support frame, the output end of the rotation drive assembly being drively connected to the rotating shaft to drive the rotating shaft to rotate; and a support frame assembly located above the support plate, one end of the support frame assembly being hinged to the support plate, and the other end being movably connected to the support plate. Next, the support frame assembly is provided with a first support part for supporting the buttocks, a second support part for supporting the armpits, and a third support part for supporting the chin. The first support part, the second support part, and the third support part are all provided with airbags for contact with the newborn's skin. This achieves the purpose that "the support plate is rotatably mounted on the support frame, and a rotation drive assembly is provided between the support plate and the support frame. Therefore, the state of the support plate can be adjusted so that the support plate can switch between a horizontal position and a vertical position. When the support plate is in the horizontal position, the newborn can be placed directly on the support plate and fixed by the support frame assembly without the need for family members or medical staff to lift and adjust the newborn's position."
[0004] However, when the above device is in use, the support plate is switched between vertical and horizontal states via a rotating shaft. When the support plate is switched from horizontal to vertical, the device, which was originally in a balanced state, will become unbalanced due to the change in the position of the newborn and the support plate. This will cause the device to tip over, and the tipping direction will be towards the newborn, resulting in injury to the newborn.
[0005] To address this issue, we propose a multi-angle adjustable neonatal radiation protection device. Summary of the Invention
[0006] Technical problems to be solved
[0007] In view of this, and in view of the shortcomings of the prior art, the present invention provides a multi-angle adjustable neonatal radiation protection device to solve the problems mentioned in the background art.

[0016] Preferably, it also includes a limiting component disposed on the support plate;
[0017] The limiting components include a headrest fixedly installed on the outer surface of one side of the top of the support plate, a neck limiting component rotatably connected to the outer surface of one side of the support plate, upper limb limiting components symmetrically fixedly connected to the outer surface of one side of the support plate, lower limb limiting components fixedly installed on the bottom surface of one side of the support plate, a telescopic transparent protective cover fixedly connected to the outer surface of the support plate, a push rod fixedly installed on the outer surface of the telescopic transparent protective cover away from the support plate, and a buckle fixedly installed in a vertical direction on the outer surface of the support plate.

[0022] Beneficial effects
[0023] Compared with the prior art, the present invention provides a multi-angle adjustable neonatal radiation protection device, which has the following beneficial effects:
[0024] By incorporating a support plate, hollow telescopic connecting rod, connecting rod, and support components, the support plate maintains a balanced center of gravity when taking an upright abdominal X-ray of a newborn in a vertical position. This prevents the support plate from becoming unbalanced during use. The centered design also allows the support to self-correct, quickly restoring stability even with slight touches from medical staff. This is particularly important for newborns who are quick to react but have immature limb control, preventing falls caused by sudden movements. Furthermore, it maintains balance independently without additional counterweights or auxiliary fixation devices, freeing the operator's hands to focus on positioning and image acquisition.
[0025] Among them, the neck restraint, upper limb restraint, lower limb restraint, and telescopic transparent protective cover can restrict the position of the newborn when taking an upright abdominal X-ray, thereby assisting in taking an upright abdominal X-ray, so that no medical staff or parents need to assist in the operation and the shooting can be completed quickly.
[0026] The support component and the limiting spring work together to balance the center of gravity of the support plate when it is vertical. When the support plate is horizontal, the support component contacts the bottom surface of the support plate, supporting the center of the bottom of the support plate. When the support plate is vertical, the support component and the connecting rod form a conjugate lever system. With the elastic buffering effect of the limiting spring, the overall center of gravity is automatically constrained on the geometric center axis. This design gives the support a self-stabilizing characteristic, so that even if the newborn suddenly twists his / her limbs, he / she can quickly restore balance. As the support plate is flattened, the support component directly contacts the bottom center area, forming a triangular stable structure. At this time, the limiting spring switches to pre-tightening mode, providing an upward supporting force to counteract the gravitational torque and effectively preventing the risk of slippage caused by the tilt of the bed.
[0027] The hollow telescopic connecting rod works in conjunction with the support component to support the bottom of the horizontal support plate. The hollow telescopic connecting rod is used to support the four corner points of the support plate, and the support component is used to support the center of the support plate. At the same time, the vertical load at the four corner points of the support plate and the vertical load at the center are limited, reducing the maximum bending moment of the support plate after the newborn is placed, and effectively preventing secondary stress damage caused by the deformation of the support plate.
[0028] By setting up the arc-shaped limiting groove and the locking block, the rotation angle of the output shaft is limited. When the support plate is in a vertical position, the support plate cannot continue to rotate under the restriction of the locking block and the arc-shaped limiting groove. When the support plate rotates to a 90° vertical position, the locking block is fully embedded in the end notch of the arc-shaped limiting groove to form a rigid stop. Even if the drive motor continues to output torque due to a fault (such as a program error or power surge), it cannot break through this mechanical barrier, thus completely eliminating the risk of "uncontrolled rotation".

[0060] Further embodiments
[0061] Please see Figure 8 The multi-angle adjustable neonatal radiation protection device also includes a limiting component disposed on the support plate 11;
[0062] The limiting component includes a retaining ring 51 fixedly connected to the inner surface of the bracket plate 11 away from the drive motor 12, the inner surface of the retaining ring 51 having an arc-shaped positioning groove 52, and a retaining block 53 fixedly connected to the outer surface of the output shaft 13 away from the drive motor 12.
[0063] The output shaft 13 extends through and out of the retaining ring 51 at the end away from the drive motor 12. The arc-shaped positioning groove 52 is set as a 90-degree arc, and the retaining block 53 is slidably connected inside the arc-shaped positioning groove 52.
[0064] The overall working process and principle of the above embodiments are as follows:
[0065] Placement of newborns to be tested:
[0066] It should be noted that, as Figure 1 As shown above, the device is in a specific position when in use. When placing a newborn, the output shaft 13 needs to be rotated by the drive motor 12, which in turn causes the support plate 14, which is fixedly connected to it, to change from a vertical state to a horizontal state.
[0067] The medical staff then unfolded the neck restraint 42 with its connection point with the support plate 14 as the fulcrum, and then placed the newborn's lower limbs in the lower limb restraint 44. At this time, the newborn's two legs were located on both sides inside the lower limb restraint 44. Then, the newborn's upper limbs were placed on the upper limb restraint 43, that is, the newborn's arms were located on the upper surface of the upper limb restraint 43. Then, the neck restraint 42 was changed back to its initial state, thereby restraining the newborn's neck. At this time, the newborn's head was located on the headrest 41.
[0068] It should be noted that, in order to protect the health of newborns, the head pillow 41 is filled with sponge material, and the contact surfaces of the neck restraint 42, upper limb restraint 43 and lower limb restraint 44 with the newborn's skin are all provided with airbags to reduce the damage to the newborn's body caused by the neck restraint 42, upper limb restraint 43 and lower limb restraint 44 when supporting the newborn's body.
[0069] After the newborn is placed, the medical staff unfolds the telescopic transparent protective cover 45 on the support plate 14. At this time, the telescopic transparent protective cover 45 can cover the newborn when it is fully unfolded. The push rod 46 on the telescopic transparent protective cover 45 is located inside the buckle 47. The position of the telescopic transparent protective cover 45 is fixed by the cooperation of the buckle 47 and the push rod 46.
[0070] Newborn testing:
[0071] Then, using the casters installed at the bottom of the support plate 11, the support plate 11 is pushed to the front of the testing equipment. Then, the output shaft of the drive motor 12 is controlled to rotate in the opposite direction, which in turn drives the output shaft 13 and the support plate 14 to rotate in the opposite direction, so that the support plate 14 is changed to a vertical state again.
[0072] It should be noted that when the output shaft 13 changes the support plate 14 to a horizontal state, refer to... Figure 3 , Figure 4 as well as Figure 6 At this time, the telescopic support rod 29, which is rotatably connected to the support plate 14, will move accordingly. Through the rotatable connection between the telescopic support rod 29 and the positioning ring 28, the connecting rod 27, which is fixedly connected to the positioning ring 28, will be pulled, causing the connecting rod 27 to move from one edge of the bracket plate 11 towards the center of the bracket plate 11. Simultaneously, it will rotate towards the support plate 14. Figure 4 As shown, the synchronous movement of the connecting rod 27 is restricted by the moving ring 25 and the connecting spring 26. One of the two connecting springs 26 located on both sides of the moving ring 25 is in a compressed state and the other is in a stretched state. Therefore, when the support plate 14 rotates, the connecting rod 27 and the moving ring 25, which are no longer restricted by the telescopic support rod 29, will move from one end of the guide rod to the center of the guide rod under the synchronous action of the two connecting springs 26 and the telescopic support rod 29. Thus, when the support plate 14 is in a horizontal state, the moving ring 25 and the connecting rod 27 move synchronously to the middle part of the guide rod.
[0073] During the above process, as the connecting rod 27 moves, the limiting ring 31 set on the connecting rod 27 will move synchronously, thereby driving the support member 32 to move towards the center of the guide rod. As the support member 32 moves and the support plate 14 gradually becomes more horizontal, the distance between the top of the support member 32 and the bottom of the support plate 14 gradually decreases. At this time, the top of the support member 32 will abut against the bottom of the support plate 14, thereby causing the two connecting rods in the support member 32 to rotate in a direction away from each other on the limiting ring 31 with the connection point between the two connecting rods as the fulcrum. During the rotation of the two connecting rods, the limiting spring 33 set between the two connecting rods is stretched. At this time, the center of the horizontal support plate 14 is supported by the support member 32 and the connecting rod 27, preventing the support plate 14 from shaking.
[0074] It should also be noted that since the output shaft 13 is located at two-fifths of the support plate 14, the movement of the connecting rod 27 and the restriction of the support member 32 on the bottom of the support plate 14 are not hindered by the output shaft 13.
[0075] As the support plate 14 changes to a horizontal state, the hollow telescopic connecting rod 22, which is symmetrically rotated at its bottom end, will move synchronously. The other end of the hollow telescopic connecting rod 22 will rotate on the surface of the positioning round rod 21. Therefore, when the support plate 14 is in a horizontal state, the hollow telescopic connecting rods 22, which are symmetrically arranged and located at the four corners of the support plate 14, will support the four corners of the support plate 14, and the support member 32 will support the center of the support plate 14, thereby preventing the support plate 14 from becoming unbalanced.
[0076] Furthermore, when the support plate 14 switches to a horizontal or vertical state under the action of the output shaft 13, the output shaft 13 will rotate inside the retaining ring 51. At the same time, the retaining block 53, which is fixedly connected to the surface of the end of the output shaft 13 away from the drive motor 12, will slide synchronously inside the arc-shaped positioning groove 52. Since the arc-shaped positioning groove 52 is set as a 90-degree arc, the movement trajectory of the retaining block 53 inside the arc-shaped positioning groove 52 will be restricted synchronously, thereby restricting the position of the output shaft 13 through the retaining block 53.
[0077] By setting the arc-shaped limiting groove and the locking block 53, the rotation angle of the output shaft 13 is limited. When the support plate 14 is in a vertical state, the support plate 14 cannot continue to rotate under the restriction of the locking block 53 and the arc-shaped limiting groove. When the support plate 14 rotates to a 90° vertical position, the locking block 53 is fully embedded in the end notch of the arc-shaped limiting groove to form a rigid stop. Even if the drive motor 12 continues to output torque due to a fault (such as a program error or power surge), it cannot break through this mechanical barrier, thus completely eliminating the risk of "uncontrolled rotation".
[0078] Based on the above-described motion process, when the support plate 14 returns to a vertical position under the action of the output shaft 13, the remaining structures will move in the reverse direction according to the above steps until they return to the vertical position. Figure 2 As shown in the diagram, the medical staff places the device in front of the radiology equipment, so that the top of the side surface of the support plate 14 on which the positioning rod 21 is installed is in contact with the surface of the radiology equipment. At this time, the newborn is in an upright position, which makes it easier for the medical staff to take an upright abdominal X-ray.
[0079] It should be noted that even if the newborn is light, when taking an upright abdominal X-ray, the newborn is located on one side of the support plate 14, and the state of the support plate 14 is maintained by the drive motor 12 and the output shaft 13. Therefore, the center of gravity of the device is unbalanced at this time, and the device may tip over during use. The vertical moving ring 25, connecting rod 27 and telescopic support rod 29 are all located on the side of the support plate 14 away from the newborn. The two ends of the telescopic support rod 29 have different weights. The heavier end of the telescopic support rod 29 is located at its connection with the positioning ring 28. The support member 32 and the limiting ring 31 on the connecting rod 27 are also made of heavier materials and have a certain weight. Thus, the above structure balances the center of gravity of the support plate 14 in the vertical state, thereby reducing the risk of the device tipping over.
[0080] After the upright abdominal X-ray is taken, the output shaft of the drive motor 12 is rotated again according to the above steps to change the support plate 14 to a horizontal state. The medical staff then reverses the operation of the device according to the above steps to quickly remove the newborn from the surface of the support plate 14, thus avoiding any impact on the newborn's body.
[0081] With the support plate 14, hollow telescopic connecting rod 22, connecting round rod 27, and support member 32, when the support plate 14 is in a vertical position for taking an abdominal X-ray of a newborn, the overall center of gravity of the support plate 11 can be kept in a balanced state, thus preventing the support plate 11 from becoming unbalanced during use. The centrally located center of gravity design gives the support a self-correcting ability, allowing it to quickly return to a stable state even if slightly touched by medical staff. This is especially important for newborns who are quick to react but have immature limb control, as it can prevent falls caused by sudden movements. Moreover, it can maintain balance independently without additional counterweights or auxiliary fixation devices, freeing the operator's hands so that they can focus on positioning and image acquisition.
[0082] Among them, the neck restraint 42, upper limb restraint 43, lower limb restraint 44 and telescopic transparent protective cover 45 can restrict the position of the newborn when taking an upright abdominal X-ray, thereby assisting in taking an upright abdominal X-ray, so that no medical staff or parents need to assist in the operation and the shooting can be completed quickly.
[0083] The support member 32 and the limiting spring 33 are designed to balance the center of gravity of the support plate 14 when the support plate 14 is in a vertical state, in conjunction with the connecting rod 27. When the support plate 14 is in a horizontal state, the support member 32 contacts the bottom surface of the support plate 14, supporting the center of the bottom of the support plate 14. When the support plate 14 is vertical, the support member 32 and the connecting rod 27 form a conjugate lever system. With the elastic buffering effect of the limiting spring 33, the overall center of gravity is automatically constrained on the geometric center axis. This design gives the support a self-stabilizing characteristic, so that even if the newborn suddenly twists his / her limbs, he / she can quickly restore the balance. As the support plate 14 is laid flat, the support member 32 directly contacts the bottom center area, forming a triangular stable structure. At this time, the limiting spring 33 switches to a pre-tightened mode, providing an upward supporting force to counteract the gravitational torque and effectively preventing the risk of slippage caused by the tilt of the bed surface.
[0084] The hollow telescopic connecting rod 22 cooperates with the support member 32 to support the bottom of the horizontal support plate 14. The hollow telescopic connecting rod 22 is used to support the four corner points of the support plate 14, and the support member 32 is used to support the center of the support plate 14. At the same time, the vertical loads at the four corner points of the support plate 14 and the vertical loads at the center are limited, reducing the maximum bending moment of the support plate 14 after the newborn is placed, and effectively preventing secondary stress damage caused by deformation of the support plate 14.
