Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and specifically relates to an auxiliary fixing device for neonatal radiography during nursing care. Background Art

[0002] During the neonatal medical diagnosis process, radiography is an important means to evaluate skeletal development, the condition of internal organs, etc. As a key device to ensure the quality of radiography, the auxiliary fixing device for neonatal radiography during nursing care needs to achieve stable and precise body position fixation on the premise of ensuring the safety of neonates, so as to obtain clear imaging data and provide a reliable basis for subsequent diagnosis and treatment.

[0003] For example, the utility model with the publication number CN213249193U provides a restraint device for X-ray shooting of unaccompanied neonates, which relates to the technical field of medical auxiliary equipment and solves the technical problem that during X-ray examination in the prior art, parents and medical staff cannot accompany, and the limbs of neonates are prone to dancing and the head is prone to swaying, which easily causes the failure of radiography. The restraint device includes a bag body for sleeving outside the imaging plate, a soft pillow for supporting the head, a length adjustment component for adjusting the size of the break opening between the two ends of the soft pillow, at least two first restraint belts for fixing the elbow parts, and at least two second restraint belts for fixing the knee parts. The first restraint belts and the second restraint belts are both detachably connected to the bag body. The present utility model can fix the head, arms and legs of neonates, conforms to the natural relaxation body position of neonates, has high comfort, and can fully expose the chest and abdomen without the need for others to accompany. The present utility model is used to improve the success rate of neonatal radiography; When the above device is in use, by setting a plurality of restraint belts, the arms and legs of neonates are fixed. However, due to the growth environment and physiological development characteristics of neonates in the mother's body, their legs are in a natural bent frog-leg shape. When the above device is fixed, it is necessary to forcibly straighten and fix the legs of neonates. Therefore, it may cause strong discomfort and crying of neonates, and even more seriously, it may cause irreversible damage to the joints, bones and soft tissues of neonates that are still developing. Most of the existing radiography devices use simple straps or rigid fixing frames, which are difficult to adapt to the special shape of neonates' legs, so it is difficult to effectively fix the legs of neonates, thus seriously affecting the radiography effect and diagnostic accuracy. Therefore, an auxiliary fixing device for neonatal radiography during nursing care is proposed to solve the problems raised in the background art. Summary of the Invention

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figures 1 to 8 shown, the present invention provides an auxiliary fixing device for neonatal care radiography, including a support frame 1, and further including: A support component 2, the support component 2 is symmetrically arranged inside the support frame 1, and a fixing component 4 is installed inside the support component 2; An adjustment device 3, the adjustment device 3 is movably connected inside the support frame 1, and the adjustment device 3 is located between the two support components 2; A limiting component 5, the limiting component 5 is arranged on the top of the support frame 1; Among them, the support component 2 includes a rotating shaft 21, two connecting rods 22 are fixedly connected to the middle of the outer wall of the rotating shaft 21, a placing rack 23 is fixedly connected to the top of the connecting rod 22, and a gear 24 is fixedly connected to one end of the connecting rod 22 close to the adjustment device 3; The fixing component 4 includes an air pump 41, an air delivery pipe 42 is fixedly connected to the output end of the air pump 41, airbags 43 are fixedly connected to both ends of the top of the air delivery pipe 42, and a button 44 is installed on one side of the placing rack 23.

[0022] Adopting the above scheme: Since the placement rack 23 is semi-circular, it is convenient to fit with the bent legs of the newborn. By pressing the button 44, the circuit inside the placement rack 23 is closed, thereby starting the air pump 41, and injecting air into the two airbags 43 through the air supply pipe 42. After the airbags 43 are inflated, they fit with the leg skin and apply a gentle and uniform pressure to the legs, thereby restricting the involuntary movement of the legs and effectively fixing the bent legs of the newborn.

[0023] As Figure 4 , Figure 5 shown, the adjusting device 3 includes a square plate 31. Two inclined grooves 32 are opened on the surface of the square plate 31, and the orientations of the two inclined grooves 32 are opposite. Two toothed blocks 33 are symmetrically and movably connected inside the support frame 1. One end of the toothed block 33 is provided with a round rod, and the round rod is movably clamped inside the inclined groove 32. A square groove 38 for limiting the toothed block 33 in the horizontal direction is opened on the inner wall of the support frame 1. When the square plate 31 moves downward, the toothed block 33 is driven to move horizontally toward the direction of the gear 24 through the inclined groove 32, and after the toothed block 33 moves, it is clamped with the gear 24.

[0024] Adopting the above scheme: The placement rack 23 can be adjusted according to the original angle of the newborn's legs, so that the angle after the placement rack 23 is tilted is the most comfortable angle for placing the newborn's legs. Subsequently, by pressing the square plate 31, due to the opposite orientations of the two inclined grooves 32, the toothed block 33 moves horizontally along the track of the inclined groove 32 and moves in a straight line under the limitation of the square groove 38, thereby being clamped with the gear 24, and then fixing the position after the gear 24 and the rotating shaft 21 rotate, so as to prevent the newborn from moving around during the X-ray filming, and improve the X-ray filming effect and accuracy.

[0025] As Figure 7 and Figure 8 shown, a pressure rod 35 is movably clamped on the top of the square plate 31. The top end of the pressure rod 35 penetrates through the outer wall of the support frame 1 and extends to the outside of the support frame 1. A connecting column 36 is fixedly connected to the middle of the pressure rod 35. Two sliding grooves 37 are annularly opened on the inner wall of the support frame 1, and the sliding grooves 37 are L-shaped. The connecting column 36 is movably clamped inside the sliding grooves 37. Elastic members 34 are fixedly connected to both sides of the square plate 31, and the square plate 31 is elastically connected to the support frame 1 through the elastic members 34.

[0026] Adopting the above solution: Through the design of the elastic member 34, its function is that after the neonatal radiography is completed, the operator rotates the pressure lever 35 in the reverse direction, thereby driving the connecting column 36 to slide inside the horizontal groove of the sliding groove 37. When the connecting column 36 slides into the vertical groove, at this time, the sliding groove 37 will release the limitation of the connecting column 36 in the vertical direction. Subsequently, the operator stops pressing the pressure lever 35, so that the pressure lever 35 moves upward under the action of the elastic force of the elastic member 34 to reset, and then releases the fixation of the gear 24, facilitating the next use.

[0027] As Figure 1 and Figure 3 As shown, the limiting component 5 includes a U-shaped pillow 51. Magic tape hook surfaces 52 are fixedly connected to both ends of the U-shaped pillow 51. Binding straps 53 are sewn and connected to both ends of the U-shaped pillow 51. A second gasket 54 is fixedly connected to the inner wall of the binding strap 53. One end of the binding strap 53 is provided with a magic tape loop surface that cooperates with the magic tape hook surface 52. The second gasket 54 is made of arc-shaped soft silicone material.

[0028] Adopting the above solution: After respectively placing the two bent wrists of the neonate inside the two U-shaped pillows 51, the U-shaped pillows 51 wrap the wrists. Subsequently, through the cooperation of the magic tape hook surface 52 and the magic tape loop surface at one end of the binding strap 53, the position of one end of the binding strap 53 is fixed. Then, the two binding straps 53 fix the wrists of the neonate, thereby preventing the hands of the neonate from moving randomly during the radiography process. Since the second gasket 54 is made of soft silicone material, its function is that because the skin cutin layer of the neonate is weak, it is prone to mechanical injuries such as redness, blisters, and ulcers due to external friction or compression. And the silicone material is soft and elastic, which can evenly disperse the pressure of the binding strap on the skin, thus avoiding excessive local pressure and protecting the skin of the neonate.

[0029] As Figure 5 and Figure 6 As shown, the placement rack 23 rotates around the rotating shaft 21. The placement rack 23 is semi-circular. A first gasket 25 is installed on the side of the placement rack 23 away from the airbag 43. The first gasket 25 is made of soft silicone material. Vent holes are opened on both sides of the placement rack 23. Two airbags 43 are respectively arranged at both ends on one side of the placement rack 23. The outer layer of the airbag 43 is made of PVC material, and the inner layer of the airbag 43 is made of medical cotton material.

[0030] Adopting the above solution: Through the setting of the first gasket 25, its function is that because the first gasket 25 is made of soft silicone material, due to the soft elasticity of the soft silicone, it can effectively disperse the clamping force on the legs, and setting the first gasket 25 can prevent the skin of the neonate's legs from directly contacting the surface of the placement rack 23, thereby improving the protection of the neonate's skin.

[0031] Working principle and usage process of the present invention: First, medical staff place the newborn on the support frame 1, and make the head of the newborn located in the middle of the U-shaped pillow 51. At the same time, medical staff place the two bent legs of the newborn between the two placement frames 23 respectively, and according to the angle of the leg placement, swing the direction of the placement frame 23, so that the inclination direction of the placement frame 23 adapts to the posture of the newborn's legs. Subsequently, one hand of the medical staff keeps the newborn's legs between the placement frames 23, and the other hand presses the button 44. By pressing the button 44, the circuit inside the placement frame 23 is closed, forming a complete current path, and then the motor on the air pump 41 is powered through the closed circuit, so that the air pump 41 operates; After the air pump 41 operates, it conveys air to the inside of the two air bags 43 respectively through the air delivery pipe 42, so as to realize uniform inflation of the two air bags 43. When the two air bags 43 are both filled, their inflated surfaces will closely abut against the skin of the newborn's legs, so as to apply gentle and uniform pressure on the legs, and then limit the unconscious activities of the legs, so as to accurately fix the position of the newborn's legs without causing skin damage. When the air bag 43 expands to a predetermined value and effectively limits the newborn's legs, at this time, the medical staff releases the pressing of the button 44, so that the circuit inside the placement frame 23 is disconnected, and then the air pump 41 stops operating. After the air pump 41 stops supplying air, the air pressure inside it acts on the valve core, so that it closely fits the valve seat, thereby blocking the gas return path, and then locking the air pressure inside the air bag, so that the air bag 43 always limits the newborn's legs; Subsequently, the operator presses down the pressing rod 35, so that the pressing rod 35 drives the square plate 31 to move downward, and also drives the connecting column 36 on the outer wall of the pressing rod 35 to slide inside the vertical groove of the sliding groove 37. When the square plate 31 moves downward, it will drive the round rod at one end of the tooth block 33 to slide along the track of the inclined groove 32. Since the orientations of the two inclined grooves 32 are opposite, and the square groove 38 limits the tooth block 33 in the horizontal direction, when the square plate 31 moves downward, it will drive the two tooth blocks 33 to move in opposite directions through the cooperation between the round rod and the tooth block 33, so that the tooth block 33 moves and engages with the gear 24 after moving, and then fixes the position of the gear 24 after rotation. Since the gear 24 is fixed, the rotating shaft 21 cannot drive the placement frame 23 to tilt further, so that the placement frame 23 and the legs placed inside it are fixed; When the tooth block 33 engages with the gear 24, at this time, the connecting column 36 also slides to the bottom end of the vertical groove of the sliding groove 37. At this time, the operator rotates the pressing rod 35, so that the pressing rod 35 drives the connecting column 36 to slide inside the horizontal groove at the bottom end of the sliding groove 37, and then limits the connecting column 36 in the vertical direction through the horizontal groove, so that the connecting column 36 cannot move upward, and then fixes the position of the pressing rod 35 after moving downward; Finally, medical staff place the two bent wrists of the newborn into the interiors of two U-shaped pillows 51 respectively, so that the U-shaped pillows 51 drive the second gasket 54 to abut against the wrist skin and wrap the wrists. Subsequently, medical staff paste the fuzzy surface of the strap 53 to the hook surface 52 of the Velcro, so as to fix the position of one end of the strap 53 through the cooperation between the hook surface 52 of the Velcro and the strap 53, and then fix the wrists of the newborn through the two straps 53. Furthermore, through the effective fixation of the wrists and legs by structures such as the limiting component 5, the supporting component 2, and the fixing component 4, the newborn can be prevented from moving around during the X-ray filming, thereby improving the filming effect and accuracy.
