Description

Technical Field

[0001] The present invention relates to the technical field of postoperative rehabilitation, and mainly mentions a decompression type fixed headrest for postoperative rehabilitation after craniosynostosis. Background Art

[0002] Craniosynostosis, medically known as craniosynostosis or craniofacial stenosis, is a congenital skull developmental disorder in which one or more cranial sutures close prematurely, preventing normal brain and skull growth. Normally, an infant's skull is composed of multiple bones connected by cartilage, and these connecting sutures are called cranial sutures. Their presence allows the skull to expand as the brain grows. In craniosynostosis, the cranial sutures ossify prematurely, causing the skull to not expand normally, which affects the normal development of the brain. The most common types include sagittal craniosynostosis, coronal craniosynostosis, lambdoid craniosynostosis, metopic craniosynostosis, and complex craniosynostosis. For coronal craniosynostosis, the commonly used surgical incision method is the pterional incision. The incision starts from in front of one ear, extends upward along the hairline, then crosses the top of the head, and then reaches in front of the other ear. Surgical wounds are left on both sides and the top of the head.

[0003] The wounds after coronal craniosynostosis surgery will remain on both sides and the top of the head. In subsequent postoperative rehabilitation, it is necessary to avoid applying pressure to the wound area. However, during the rest of children, they are extremely likely to lie on their sides unconsciously. But the existing methods can only support the child's head with a headrest to protect it from external pressure when lying on the back, but cannot form decompression protection against the pressure on the side of the child's head when lying on the side. The own weight of the child's head directly acts on the side of the head, causing the own gravity of the head to act on the wound on the side of the head. The wound area bears pressure under the action of the own gravity of the head, delaying the healing of the wound. Summary of the Invention

[0010] As a preference, the automatic adjustment assembly includes a third piston shaft, the third piston shaft is fixedly connected to the telescopic end of the elastic telescopic rod, the middle part of the air injection cylinder is fixedly connected and communicated with an adjustment cylinder, and the third piston shaft is in sealed sliding connection with the adjustment cylinder.

[0011] As a preference, it further includes resistance assemblies distributed in mirror image, the resistance assemblies are used to increase the resistance of the adjacent first piston shafts sliding along the air injection cylinder, the resistance assemblies are arranged on the adjacent first piston shafts, the resistance assemblies include resistance plates, the resistance plates are fixedly connected to one side of the flexible pillow close to the adjacent first piston shafts, the first piston shaft is hinged with a hinged rod, the hinged rod is provided with a one-way pulley, the one-way pulley is attached to the adjacent resistance plate, and the first piston shaft is provided with an adjustment assembly for adjusting the resistance between the adjacent one-way pulley and the adjacent resistance plate.

[0012] As a preference, the thickness of the resistance plate gradually decreases from one end close to the adjacent first piston shaft to the other end, and the joint surface of the resistance plate and the adjacent one-way pulley is a rough surface.

[0015] Compared with the prior art, the present invention has the following advantages: 1. When a child lies on the side, the power is used to inject gas into the face-attached airbag, causing the face-attached airbag to expand and support the height of the child's cheeks to rise, and then supporting the synchronous rise of the child's head, reducing the acting force between the head and the flexible pillow, further reducing the pressure on the wound of the child's head, preventing the mass of the head from directly acting on the wound, and slowing down the wound healing rate.

[0016] 2. The two second piston shafts are locked by the limiting shaft, and then the face-attached airbag and the head protection airbag are attached to both sides of the child's cheeks and head to protect the child's head.

[0017] 3. By replenishing the gas in the adjusting cylinder into the face-attached airbag, the expansion degree of the face-attached airbag is maintained, and at the same time, the initial expansion degree of the face-attached airbag is increased, preventing the situation that when the child has a large head and a large body weight, the face-attached airbag cannot support the child's head to the required height when lying on the side.

[0018] 4. The one-way pulley slides frictionally along the adjacent resistance plate to generate resistance to the movement of the first piston shaft, so that the child needs to overcome a certain resistance when turning from supine to lateral lying, thereby inhibiting the lateral lying movement of the child and reducing the probability of the child lying on the side.

Detailed implementation manners

[0028] The following is only a preferred embodiment of the present invention, and does not limit the protection scope of the present invention accordingly.

[0029] The wounds after craniosynostosis surgery will remain on both sides and the top of the head. During subsequent postoperative rehabilitation, it is necessary to avoid applying pressure to the wound area. During the rest of the child, the child is extremely likely to lie on the side unconsciously. At this time, the own weight of the child's head directly acts on the side of the head, causing the own gravity of the head to act on the wound on the side of the head. At this time, the wound area is under pressure due to the own gravity of the head, delaying the healing of the wound. The existing method can only support the child's head with a headrest to prevent it from being damaged by external pressure when lying on the back, but it cannot form decompression protection for the pressure borne by the side of the child's head when lying on the side, thus affecting the healing of the wound.

[0030] Embodiment 1: A decompression - type fixed headrest for postoperative rehabilitation of craniosynostosis, please refer to Figures 1-4, including a flexible pillow 1. Rotating rollers 2 are rotatably connected to both the left and right sides inside the flexible pillow 1. Two mirror-image distributed rotating rollers 2 are fixedly connected and wound with cable ropes 3. Two mirror-image distributed first elastic elements 4 are arranged between the two mirror-image distributed rotating rollers 2 and the flexible pillow 1. The first elastic element 4 is a torsion spring, and the first elastic element 4 is used to drive the adjacent rotating roller 2 to reset. The first elastic element 4 is in a twisted state initially. Gears 5 are fixedly connected to the rear sides of the two mirror-image distributed rotating rollers 2. An air injection cylinder 6 is fixedly connected to the rear side of the flexible pillow 1. Two mirror-image distributed cable ropes 3 are fixedly connected with face-attached airbags 7. Protective head airbags 8 are fixedly connected to the rear sides of the two mirror-image distributed face-attached airbags 7. The protective head airbag 8 is arc-shaped, facilitating adaptation to the contour of the skull, and has a hollow structure inside, so that the postoperative wound is located inside the protective head airbag 8, avoiding the direct contact between the protective head airbag 8 and the postoperative wound. Two mirror-image distributed first piston shafts 9 are hermetically slidably connected to the air injection cylinder 6. The two mirror-image distributed first piston shafts 9 and the air injection cylinder 6 cooperate to form a sealed cavity. The far ends of the two mirror-image distributed first piston shafts 9 are fixedly connected with racks 10. The two mirror-image distributed racks 10 are respectively engaged with the adjacent gears 5. The gear 5 drives the adjacent first piston shaft 9 to slide along the air injection cylinder 6 through the adjacent rack 10. Two mirror-image distributed face-attached airbags 7 and the air injection cylinder 6 are jointly fixedly connected with a first air injection pipe 11. The sealed cavity formed by the cooperation of the two mirror-image distributed first piston shafts 9 and the air injection cylinder 6 is communicated with the two mirror-image distributed face-attached airbags 7 through the first air injection pipe 11. When the first piston shaft 9 slides inward along the air injection cylinder 6, the gas in the sealed cavity formed by the cooperation of the two first piston shafts 9 and the air injection cylinder 6 is pushed into the two face-attached airbags 7 through the first air injection pipe 11, causing the face-attached airbags 7 to expand and support the cheeks of the child to rise, thereby driving the skull of the child to rise synchronously, reducing the acting force between the skull and the flexible pillow, avoiding the mass of the skull directly acting on the wound, and slowing down the healing rate of the wound. Fixing components are arranged on the two mirror-image distributed protective head airbags 8 for fixing themselves.

[0031] Please refer to Figure 4 and Figure 5 , the fixing components include two mirror-image distributed second piston shafts 201. The two mirror-image distributed second piston shafts 201 are respectively fixedly connected to the rear sides of the adjacent protective head airbags 8. The two mirror-image distributed second piston shafts 201 are jointly slidably connected to a docking shell 202. A second elastic element 203 is arranged between the two mirror-image distributed second piston shafts 201. The second elastic element 203 is a tension spring, and the second elastic element 203 is used to drive the two second piston shafts 201 to reset. The second elastic element 203 is located inside the docking shell 202. Locking components are arranged on the two mirror-image distributed second piston shafts 201 for locking themselves.

[0032] Please refer to Figure 4 and Figure 5, the locking component includes a linear array of serrated blocks 301. The linear array of serrated blocks 301 are all fixedly connected to the adjacent second piston shafts 201. One side of the docking shell 202 close to the adjacent linear array of serrated blocks 301 is slidably connected with a limiting shaft 302. The linear array of serrated blocks 301 are all in limiting cooperation with the adjacent limiting shaft 302. The serrated block 301 locks the adjacent second piston shaft 201 through the limiting shaft 302, so as to fit the face-hugging airbag 7 and the head-protecting airbag 8 to both sides of the child's cheek and head. A third elastic element 303 is arranged between the limiting shaft 302 and the docking shell 202. The third elastic element 303 is a tension spring. The third elastic element 303 is used to drive the adjacent limiting shaft 302 to reset. The docking shell 202 is provided with a detection component for detecting the distance between the mirror-distributed face-hugging airbags 7.

[0033] Please refer to Figures 2-4 and Figure 6 , the detection component includes an elastic telescopic rod 401. The elastic telescopic rod 401 is fixedly connected to the outside of the air injection cylinder 6. The mirror-distributed second piston shafts 201 and the docking shell 202 cooperate to form a sealed cavity. The volume of the child's head is detected by the sliding distance of the two second piston shafts 201 along the docking shell 202. A second air injection pipe 402 is fixedly connected between the docking shell 202 and the fixed part of the elastic telescopic rod 401. A spring for resetting the telescopic end of the elastic telescopic rod 401 is arranged in the fixed part of the elastic telescopic rod 401. The elastic coefficient of the third elastic element 303 is greater than the elastic coefficient of the spring in the fixed part of the elastic telescopic rod 401. The sealed cavity is communicated with the second air injection pipe 402. The fixed part of the elastic telescopic rod 401 is communicated with the second air injection pipe 402. The second piston shaft 201 slides away from the docking shell 202, so that the gas in the fixed part of the elastic telescopic rod 401 enters the sealed cavity, and the telescopic end of the elastic telescopic rod 401 slides inward along its fixed part. The air injection cylinder 6 is provided with a self-adjusting component for adjusting the initial pressure in the face-hugging airbag 7.

[0034] Please refer to Figure 6, the self-adjusting component includes a third piston shaft 403, the third piston shaft 403 is fixedly connected to the telescopic end of the elastic telescopic rod 401, the middle of the air injection cylinder 6 is fixedly connected and communicated with an adjusting cylinder 404, the third piston shaft 403 is hermetically slidably connected with the adjusting cylinder 404, and the telescopic end of the elastic telescopic rod 401 drives the third piston shaft 403 to slide inward along the adjusting cylinder 404, so that the gas in the adjusting cylinder 404 flows through the air injection cylinder 6 and enters the two face-attachment air bags 7 along the first air injection pipe 11. The cross-sectional area of the docking shell 202 is larger than that of the air injection cylinder 6. When the child's head is fixed and the distance between the face-attachment air bags 7 increases, the reduction amount of the gas in the face-attachment air bags 7 is less than the injection amount of the gas in the adjusting cylinder 404 injected into the face-attachment air bags 7 by the third piston shaft 403. By supplementing the gas in the adjusting cylinder 404 into the face-attachment air bags 7, the expansion degree of the face-attachment air bags 7 is maintained, and at the same time, the initial expansion degree of the face-attachment air bags 7 is increased, so as to avoid the situation that the face-attachment air bags cannot support the child's head to the required height when the child has a large head and heavy weight and lies on the side.

[0035] When the child needs to sleep after craniosynostosis surgery, the staff pulls the two second piston shafts 201 distributed mirror-symmetrically to slide away from each other along the docking shell 202. At the same time, the second elastic element 203 is stretched. At this time, the second piston shafts 201 drive the serrated blocks 301 arranged in a linear array thereon to move synchronously. The serrated blocks 301 arranged in a linear array squeeze the adjacent limiting shafts 302, and the limiting shafts 302 slide along the docking shell 202, so that the third elastic element 303 is stretched. After the distance between the two face-attachment air bags 7 distributed mirror-symmetrically and the two head-protecting air bags 8 distributed mirror-symmetrically is the same as the distance between the sides of the child's head, at this time, the sliding of the two second piston shafts 201 distributed mirror-symmetrically is stopped. Then the third elastic element 303 resets and drives the adjacent limiting shafts 302 to reset, so that the limiting shafts 302 contact the adjacent serrated blocks 301, and the limiting shafts 302 lock the adjacent second piston shafts 201. Then the two face-attachment air bags 7 are attached to the child's cheeks, and at the same time, the two head-protecting air bags 8 are attached to both sides of the head, and the surgical wound is located in the hollow of the head-protecting air bag 8. By locking the two second piston shafts 201 with the limiting shafts 302, the face-attachment air bags 7 and the head-protecting air bags 8 are attached to the child's cheeks and both sides of the head, respectively, to protect the child's head. At this time, the initial protection of the child's head is completed.

[0036] When fixing the face - adhering airbag 7 and the head - protecting airbag 8 to a child's head, as the distance between the two face - adhering airbags 7 increases, the two first elastic elements 4 distributed symmetrically on both sides reset and drive the adjacent roller 2 to rotate. The roller 2 winds up the adjacent cable 3. At the same time, the roller 2 drives the adjacent gear 5 to rotate. The gear 5 drives the first piston shaft 9 to slide along the air injection cylinder 6 through the rack 10, causing the two first piston shafts 9 distributed symmetrically to slide away from each other. As a result, the gas in the two face - adhering airbags 7 distributed symmetrically flows back into the air injection cylinder 6. At this time, the two face - adhering airbags 7 distributed symmetrically contract. At the same time, the two second piston shafts 201 distributed symmetrically pull outward along the docking shell 202. At this time, the volume of the sealed cavity formed by the cooperation of the second piston shaft 201 distributed symmetrically and the docking shell 202 increases. At this time, the gas in the fixed part of the elastic telescopic rod 401 enters the sealed cavity formed by the cooperation of the second piston shaft 201 distributed symmetrically and the docking shell 202 along the second injection pipe 402. The telescopic end of the elastic telescopic rod 401 slides inward along its fixed part. The telescopic end of the elastic telescopic rod 401 drives the third piston shaft 403 thereon to slide inward along the adjustment cylinder 404. The third piston shaft 403 pushes the gas in the adjustment cylinder 404 into the air injection cylinder 6. The gas in the air injection cylinder 6 enters the two face - adhering airbags 7 distributed symmetrically along the first injection pipe 11. The gas in the face - adhering airbags 7 increases, so that the gas in the two face - adhering airbags 7 returns to the initial expansion degree, and at the same time expands further on the original volume of the face - adhering airbag 7, avoiding the situation that the face - adhering airbag 7 cannot support the child's head to the required height when the child has a large head and heavy weight and lies on the side.

[0037] When a child is in a sleeping state, it is very easy to have a side - lying phenomenon, which will cause pressure on the surgical wound areas on both sides of the child's head, and is not conducive to the recovery of the wound. When the child has a side - lying phenomenon, at this time, the child's head will drive the two face - adhering airbags 7 distributed symmetrically thereon to change positions. The two face - adhering airbags 7 deflect from the horizontal symmetric distribution to the vertical symmetric distribution. At this time, the deflection of the face - adhering airbag 7 pulls the adjacent cable 3. The cable 3 drives the adjacent roller 2 to rotate. At the same time, the two first elastic elements 4 distributed symmetrically adjacent thereto are twisted. The rotation of the roller 2 drives the adjacent gear 5 to rotate. The gear 5 drives the adjacent rack 10 to move. The rack 10 drives the adjacent first piston shaft 9 to push inward along the air injection cylinder 6. The gas in the air injection cylinder 6 is pushed by the driving force and enters the two face - adhering airbags 7 along the first injection pipe 11. At this time, the volume of the gas in the face - adhering airbags 7 increases, and then drives the face - adhering airbags 7 to gradually expand, so that the face - adhering airbags 7 expand to support the child's cheeks. The height of the child's cheeks rises, and then supports the synchronous rise of the child's head, reducing the acting force of the head flexible pillow 1, reducing the pressure on the child's head wound, avoiding the direct action of the mass of the head on the wound, and slowing down the wound healing rate.

[0038] When the staff observes that the child shows a side-lying position, they turn the child into a supine position. At this time, the first elastic element 4 resets and drives the adjacent roller 2 to reset. The roller 2 resets and winds the adjacent cable 3. At the same time, the roller 2 drives the adjacent gear 5 to reset and rotate. The gear 5 drives the first piston shaft 9 to reset through the adjacent rack 10. The first piston shaft 9 slides along the air injection cylinder 6, so that part of the gas in the two face-attached air bags 7 distributed in mirror image flows into the sealed cavity formed by the cooperation of the two first piston shafts 9 and the air injection cylinder 6. When the child lies on the side again, repeat the above steps.

[0039] Embodiment 2: On the basis of Embodiment 1, please refer to Figure 2 and Figure 7 , and also includes two resistance components distributed in mirror image. The resistance components are used to increase the resistance of the adjacent first piston shaft 9 sliding along the air injection cylinder 6. The resistance components are arranged on the adjacent first piston shafts 9. The resistance components include resistance plates 501. The thickness of the resistance plates 501 gradually decreases from the middle to the outside of the flexible pillow 1. The resistance plates 501 are fixedly connected to the rear side of the flexible pillow 1. The first piston shaft 9 is hinged with a hinge rod 502. The hinge rod 502 is provided with a one-way pulley 503. The one-way pulley 503 cannot rotate when sliding along the resistance plate 501 towards the middle of the flexible pillow 1. The one-way pulley 503 can rotate when sliding along the resistance plate 501 from the middle of the flexible pillow 1 to the outside. The one-way pulley 503 is in contact with the adjacent resistance plate 501, and the contact surface between the resistance plate 501 and the adjacent one-way pulley 503 is a rough surface. The first piston shaft 9 is provided with an adjustment component for adjusting the resistance between the adjacent one-way pulley 503 and the adjacent resistance plate 501. By the friction sliding of the one-way pulley 503 along the adjacent resistance plate 501, a resistance is generated on the movement of the first piston shaft 9, so that when the child turns from a supine position to a side-lying position, a certain resistance needs to be overcome, thereby suppressing the side-lying movement of the child and reducing the probability of the child lying on the side.

[0040] Please refer to Figure 8 , the adjustment component includes a rotating ring 504. The rotating ring 504 is rotatably connected to one end of the adjacent first piston shaft 9 close to the adjacent hinge rod 502. The rotating ring 504 is rotatably connected to the adjacent hinge rod 502. A fourth elastic element 505 is arranged between the rotating ring 504 and the adjacent hinge rod 502. The fourth elastic element 505 is a torsion spring. The fourth elastic element 505 is used to increase the fitting force between the one-way pulley 503 and the adjacent resistance plate 501. One end of the first piston shaft 9 close to the adjacent resistance plate 501 is provided with a limiting component for locking the adjacent rotating ring 504. By rotating the rotating ring 504, a torsion force is applied to the adjacent fourth elastic element 505. The torsion force of the fourth elastic element 505 increases the fitting force between the adjacent one-way pulley 503 and the adjacent resistance plate 501 through the adjacent hinge rod 502, and adjusts the sliding friction force of the one-way pulley 503 along the adjacent resistance plate 501.

[0041] Please refer toFigure 8 The limiting component includes a plug shaft 506 which is threadedly connected to the adjacent rotating ring 504 in a penetrating manner. The first piston shaft 9 is provided with a circumferentially-arrayed limiting hole 507. The circumferentially-arrayed limiting holes 507 are all in limiting cooperation with the adjacent plug shafts 506. The plug shaft 506 passes through the rotating ring 504 and enters the adjacent limiting hole 507 to lock the adjacent rotating ring 504, so as to keep the torsion of the adjacent fourth elastic element 505 unchanged.

[0042] After the face-attached airbag 7 and the head-protecting airbag 8 are fixed to the child's head, at this time, the staff rotates the two rotating rings 504 according to the age of the child. The rotating ring 504 rotates along the adjacent first piston shaft 9. The rotating ring 504 drives the adjacent fourth elastic element 505 to twist. The twisting of the fourth elastic element 505 drives the adjacent one-way pulley 503 to further fit the adjacent resistance plate 501 through the adjacent hinge rod 502, increasing the supporting force of the resistance plate 501 on the adjacent one-way pulley 503, and further increasing the friction force of the one-way pulley 503 sliding along the resistance plate 501. When the rotating ring 504 rotates to the required position, the staff rotates the plug shaft 506 into the rotating ring 504, and at the same time makes the plug shaft 506 enter the limiting hole 507 behind the first piston shaft 9, so that the plug shaft 506 limits and locks the rotating ring 504. At this time, the adjustment is completed. By twisting the fourth elastic element 505 through the rotating ring 504, the twisting force of the fourth elastic element 505 drives the one-way pulley 503 to further fit the resistance plate 501, increasing the supporting force of the resistance plate 501 on the adjacent one-way pulley 503, and further increasing the friction force of the one-way pulley 503 sliding along the resistance plate 501.

[0043] When the rack 10 drives the adjacent first piston shaft 9 to push inward along the air injection cylinder 6, at this time, the first piston shaft 9 pulls the hinge rod 502 thereon to move synchronously. The hinge rod 502 pulls the adjacent one-way pulley 503 to slide synchronously along the adjacent resistance plate 501. At this time, the one-way pulley 503 does not rotate. The one-way pulley 503 produces frictional sliding along the adjacent resistance plate 501, thereby generating resistance to the movement of the first piston shaft 9, so that the child needs to overcome a certain resistance when turning from a supine position to a lateral position, thereby inhibiting the lateral position movement of the child and reducing the probability of the child's lateral position occurrence. At the same time, as the one-way pulley 503 gradually slides along the resistance plate 501, the height of the resistance plate 501 gradually increases. The resistance plate 501 squeezes the adjacent one-way pulley 503, so that the one-way pulley 503 drives the adjacent hinge rod 502 to deflect along the adjacent first piston shaft 9, further twisting the fourth elastic element 505, and further gradually increasing the friction force of the one-way pulley 503 sliding along the resistance plate 501, further inhibiting the progress of the child's lateral position movement.

[0044] When the first piston shaft 9 is reset along the air injection cylinder 6, the first piston shaft 9 drives the adjacent hinge rod 502 to be reset synchronously at this time. The hinge rod 502 drives the one-way pulley 503 to be reset synchronously. At this time, the one-way pulley 503 can rotate, so that the one-way pulley 503 rotates and travels along the adjacent resistance plate 501 for reset.

[0045] The above are only embodiments of the present invention, and thus do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
