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 of craniosynostosis. Background Art

[0002] Craniosynostosis, medically known as craniosynostosis or craniosynostosis, is a congenital skull developmental abnormality in which one or more cranial sutures close prematurely, preventing normal brain and skull growth. Normally, an infant's skull is made up of multiple bones connected by cartilage. These connecting sutures are called cranial sutures. Their existence allows the skull to expand as the brain grows. In craniosynostosis, the cranial sutures ossify prematurely, resulting in the skull being unable to expand normally, which affects the normal development of the brain. The most common types include sagittal suture closure, coronal suture closure, lambdoid suture closure, frontal suture closure and complex craniosynostosis. The surgical incision for coronal suture closure often uses a wing-shaped incision. The incision starts in front of one ear, extends upward along the hairline, then crosses the top of the head, and then goes down to in front of the other ear, leaving surgical wounds on both sides of the skull and the top of the head.

[0003] After coronal suture closure surgery, wounds will remain on both sides and the top of the head. In the subsequent postoperative rehabilitation, it is necessary to avoid applying pressure to the wounds. However, when children are resting, they are very likely to lie on their side in an unconscious state. However, the existing method can only support the child's head with a headrest to prevent the child from being harmed by external pressure when lying on his back, but it cannot form decompression protection for the pressure on the side of the child's head when lying on his side. The child's own weight of the head directly acts on the side of the head, so that the head's own gravity acts on the wound on the side of the head. The wound is under pressure due to the head's own gravity, which delays the healing of the wound. Summary of the invention

DETAILED DESCRIPTION

[0021] The following descriptions are merely preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.

[0022] The wounds after coronal suture closure surgery will remain on both sides and the top of the head. In the subsequent postoperative rehabilitation, it is necessary to avoid applying pressure to the wounds. During the resting process, children are very likely to lie on their side in an unconscious state. At this time, the weight of the child's head directly acts on the side of the head, causing the head's own gravity to act on the wound on the side of the head. At this time, the wound is under pressure due to the head's own gravity, delaying the healing of the wound. The existing method can only support the child's head through a headrest, so that it is not harmed by external pressure when lying on its back, but it cannot form decompression protection for the pressure on the side of the child's head when lying on its side, thereby affecting the healing of the wound.

[0023] Example 1: A decompression fixed headrest for postoperative rehabilitation of craniosynostosis, see Figure 1-Figure 4, including a flexible pillow 1, wherein the left and right sides of the flexible pillow 1 are rotatably connected with rollers 2, the two mirror-distributed rollers 2 are fixedly connected and wrapped with cables 3, the two mirror-distributed rollers 2 are each provided with two mirror-distributed first elastic elements 4 between the flexible pillow 1, the first elastic element 4 is a torsion spring, the first elastic element 4 is used to drive the adjacent rollers 2 to reset, the first elastic element 4 is initially in a torsion state, the rear sides of the two mirror-distributed rollers 2 are fixedly connected with gears 5, the rear side of the flexible pillow 1 is fixedly connected with an injection cylinder 6, the two mirror-distributed cables 3 are fixedly connected with face-attached airbags 7, the rear sides of the two mirror-distributed face-attached airbags 7 are fixedly connected with head-protecting airbags 8, the head-protecting airbags 8 are arc-shaped, which is convenient for adapting to the contour of the head, and the interior is a hollow structure, so that the postoperative wound is located in the head-protecting airbag 8, avoiding direct contact between the head-protecting airbag 8 and the postoperative wound, the injection cylinder 6 is sealingly and slidably connected with two mirror-distributed first piston shafts 9, and the two mirror-distributed first piston shafts 9 cooperate with the injection cylinder 6 to form a tight The closed cavity body, the distal ends of the two mirror-distributed first piston shafts 9 are fixedly connected with racks 10, and the two mirror-distributed racks 10 are respectively meshed with adjacent gears 5, and the gears 5 drive the adjacent first piston shafts 9 to slide along the gas injection cylinder 6 through the adjacent racks 10. The two mirror-distributed face airbags 7 and the gas injection cylinder 6 are jointly fixedly connected with the first gas injection pipe 11. The two mirror-distributed first piston shafts 9 cooperate with the gas injection cylinder 6 to form a closed cavity, which is connected with the two mirror-distributed face airbags 7 through the first gas injection pipe 11. The first piston shaft 9 slides inwardly along the gas injection cylinder 6, and the gas in the closed cavity formed by the two first piston shafts 9 and the gas injection cylinder 6 is pushed into the two face airbags 7 through the first gas injection pipe 11, so that the face airbags 7 expand and support the child's cheeks to rise, thereby driving the child's head to rise synchronously, reducing the force between the head and the flexible pillow, avoiding the mass of the head from directly acting on the wound, and slowing down the healing rate of the wound. The two mirror-distributed head protection airbags 8 are provided with a fixing component for fixing themselves.

[0024] See also Figure 4 and Figure 5 The fixing component includes two second piston shafts 201 with mirror distribution, and the two second piston shafts 201 with mirror distribution are respectively fixedly connected to the rear sides of adjacent head guard airbags 8, and the two second piston shafts 201 with mirror distribution are slidably connected with a docking shell 202. A second elastic element 203 is arranged between the second piston shafts 201 with mirror distribution, and the second elastic element 203 is a tension spring. The second elastic element 203 is used to drive the two second piston shafts 201 to reset, and the second elastic element 203 is located inside the docking shell 202. The two second piston shafts 201 with mirror distribution are both provided with a locking component for locking themselves.

[0025] See also Figure 4 and Figure 5The locking assembly includes a linear array of sawtooth blocks 301, which are fixedly connected to adjacent second piston shafts 201. The docking shell 202 is slidably connected to a limiting shaft 302 on one side of the sawtooth blocks 301 close to the adjacent linear array. The sawtooth blocks 301 of the linear array are limitedly matched with adjacent limiting shafts 302. The sawtooth blocks 301 lock the adjacent second piston shafts 201 through the limiting shafts 302, so that the face-attaching airbags 7 and the head-protecting airbags 8 are attached to the cheeks and both sides of the head of the child. 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 shafts 302 to reset. The docking shell 202 is provided with a detection component for detecting the distance between the mirror-distributed face-attaching airbags 7.

[0026] See also Figure 2-Figure 4 and Figure 6 The detection component includes an elastic telescopic rod 401, which is fixedly connected to the outside of the gas injection cylinder 6. The second piston shaft 201 distributed in a mirror image cooperates with the docking shell 202 to form a closed 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. The docking shell 202 and the fixed part of the elastic telescopic rod 401 are fixedly connected with a second gas injection tube 402. The fixed part of the elastic telescopic rod 401 is provided with a spring for resetting its telescopic end. The third elastic The elastic coefficient of element 303 is greater than the elastic coefficient of the spring in the fixed part of the elastic telescopic rod 401. The closed cavity is connected to the second gas injection pipe 402. The fixed part of the elastic telescopic rod 401 is connected to the second gas injection pipe 402. The second piston shaft 201 slides backward along the docking shell 202, so that the gas in the fixed part of the elastic telescopic rod 401 enters the closed cavity, and the telescopic end of the elastic telescopic rod 401 slides inward along its fixed part. The gas injection cylinder 6 is provided with a self-adjusting component for adjusting the initial pressure in the face-fitting airbag 7.

[0027] See also Figure 6The self-adjusting component includes a third piston shaft 403, which is fixedly connected to the telescopic end of the elastic telescopic rod 401, and the middle part of the gas injection cylinder 6 is fixedly connected and connected with the regulating cylinder 404. The third piston shaft 403 is sealed and slidably connected with the regulating cylinder 404. The telescopic end of the elastic telescopic rod 401 drives the third piston shaft 403 to slide inward along the regulating cylinder 404, so that the gas in the regulating cylinder 404 flows through the gas injection cylinder 6 and enters the two face-attaching airbags 7 along the first gas injection pipe 11, and the cross section of the docking shell 202 The area is larger than the cross-sectional area of ​​the air injection cylinder 6, so that when the child's head is fixed and the distance between the face airbags 7 increases, the reduction in the gas in the face airbag 7 is less than the injection amount of the gas in the adjusting cylinder 404 into the face airbag 7 by the third piston shaft 403. By replenishing the gas in the adjusting cylinder 404 into the face airbag 7, the expansion degree of the face airbag 7 is maintained, and at the same time the initial expansion degree of the face airbag 7 is increased, to prevent the child's head from being unable to be supported to the required height by the face airbag when the child is lying on his side due to a large head and heavy body.

[0028] When the child needs to sleep after craniosynostosis surgery, the staff pulls the two second piston shafts 201 distributed in a mirror image to slide along the docking shell 202 in reverse, and the second elastic element 203 is stretched at the same time. At this time, the second piston shaft 201 drives the sawtooth blocks 301 of the linear array thereon to move synchronously, and the sawtooth blocks 301 of the 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, so that the distance between the two face-attaching airbags 7 distributed in a mirror image and the two head-protecting airbags 8 distributed in a mirror image are the same as the distance between the sides of the child's head, and then the two mirror image distributed airbags are stopped from sliding. The second piston shaft 201, and then the third elastic element 303 are reset, and the adjacent limiting shaft 302 is driven to reset, so that the limiting shaft 302 contacts the adjacent serrated block 301, and the limiting shaft 302 locks the adjacent second piston shaft 201, and then the two face-sticking airbags 7 are fitted to the child's cheeks, and at the same time, the two head protection airbags 8 are fitted to both sides of the head, and the surgical wound is located in the hollow of the head protection airbags 8. The two second piston shafts 201 are locked by the limiting shaft 302, and then the face-sticking airbags 7 and the head protection airbags 8 are fitted to the child's cheeks and both sides of the head to protect the child's head. At this time, the protection of the child's head is initially completed.

[0029] When the face airbag 7 and the head airbag 8 are fixed to the child's head, due to the increase in the distance between the two face airbags 7, the two first elastic elements 4 distributed in mirror images on both sides are reset to drive the adjacent rollers 2 to rotate, and the rollers 2 reel in the adjacent cables 3. At the same time, the rollers 2 drive the adjacent gears 5 to rotate, and the gears 5 drive the first piston shafts 9 to slide along the gas injection cylinder 6 through the rack 10, so that the two first piston shafts 9 distributed in mirror images slide in opposite directions, thereby causing the gas in the two face airbags 7 distributed in mirror images to flow back into the gas injection cylinder 6. At this time, the two face airbags 7 distributed in mirror images shrink, and at the same time, the two second piston shafts 201 distributed in mirror images are pulled outward along the docking shell 202. At this time, the volume of the closed cavity formed by the second piston shafts 201 distributed in mirror images and the docking shell 202 increases, and the elastic expansion The gas in the fixed part of the retractable rod 401 enters along the second gas injection pipe 402 into the closed cavity formed by the second piston shaft 201 and the docking shell 202 which are distributed in a mirror image. 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 adjusting cylinder 404. The third piston shaft 403 pushes the gas in the adjusting cylinder 404 to enter the gas injection cylinder 6. The gas in the gas injection cylinder 6 enters along the first gas injection pipe 11 into the two face-attached airbags 7 which are distributed in a mirror image. The gas in the face-attached airbags 7 increases, so that the gas in the two face-attached airbags 7 returns to the initial expansion degree. At the same time, the face-attached airbags 7 further expand on the original volume to prevent the face-attached airbags 7 from being unable to support the child's head to the required height when the child is lying on his side due to a large head and a heavy body.

[0030] Children are very likely to lie on their side when sleeping, which causes pressure on the surgical wounds on both sides of the child's head, which is not conducive to the recovery of the wounds. When the child lies on his side, the child's head will drive the two face-sticking airbags 7 distributed in a mirror image thereon to change their positions. The two face-sticking airbags 7 are deflected from a horizontally symmetrical distribution to a vertically symmetrical distribution. At this time, the face-sticking airbags 7 are deflected and pull the adjacent cables 3, and the cables 3 drive the adjacent rollers 2 to rotate. At the same time, the two adjacent mirror-distributed first elastic elements 4 are twisted, and the rotation of the rollers 2 drives the adjacent gears 5 to rotate, and the gears 5 drive the adjacent The adjacent rack 10 moves, and the rack 10 drives the adjacent first piston shaft 9 to be pushed inward along the gas injection cylinder 6. The gas in the gas injection cylinder 6 is driven by the driving force and enters the two face-attached airbags 7 along the first gas injection pipe 11. At this time, the volume of the gas in the face-attached airbags 7 increases, thereby driving the face-attached airbags 7 to gradually expand, so that the face-attached airbags 7 expand to support the child's cheeks. The height of the child's cheeks rises, and then the child's head is supported to rise synchronously, reducing the force of the flexible pillow 1 on the head, reducing the pressure on the wound on the child's head, avoiding the mass of the head directly acting on the wound, and slowing down the healing rate of the wound.

[0031] When the staff observes that the child lies on his side, the child is turned to a supine position. At this time, the first elastic element 4 is reset, driving the adjacent roller 2 to reset. The roller 2 resets and reels 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 gas injection cylinder 6, so that the gas in the two mirror-distributed face-attached airbags 7 partially flows to the closed cavity formed by the cooperation of the two first piston shafts 9 and the gas injection cylinder 6. When the child goes out and lies on his side again, the above steps are repeated.

[0032] Example 2: Based on Example 1, please refer to Figure 2 and Figure 7 , and also includes two resistance components with mirror distribution, the resistance component is used to increase the resistance of the adjacent first piston shaft 9 to sliding along the gas injection cylinder 6, the resistance component is arranged on the adjacent first piston shaft 9, the resistance component includes a resistance plate 501, the thickness of the resistance plate 501 gradually decreases from the middle to the outside of the flexible pillow 1, the resistance plate 501 is 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 to the middle of the flexible pillow 1, and the one-way pulley 503 moves along the resistance plate 501. The plate 501 can rotate when it slides 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, and the first piston shaft 9 is provided with an adjustment component for adjusting the resistance of the adjacent one-way pulley 503 and the adjacent resistance plate 501. The one-way pulley 503 slides along the adjacent resistance plate 501 through friction, 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 lying on his back to lying on his side, thereby inhibiting the child's side-lying movement and reducing the probability of the child lying on his side.

[0033] See also Figure 8 The adjusting component includes a swivel 504, which is rotatably connected to one end of the adjacent first piston shaft 9 close to the adjacent hinged rod 502, and the swivel 504 is rotatably connected to the adjacent hinged rod 502. A fourth elastic element 505 is arranged between the swivel 504 and the adjacent hinged rod 502, and the fourth elastic element 505 is a torsion spring. The fourth elastic element 505 is used to increase the fit between the one-way pulley 503 and the adjacent resistance plate 501, and a limiting component for locking the adjacent swivel 504 is arranged at one end of the first piston shaft 9 close to the adjacent resistance plate 501. Torsion is applied to the adjacent fourth elastic element 505 by rotating the swivel 504. The torque of the fourth elastic element 505 increases the fit between the adjacent one-way pulley 503 and the adjacent resistance plate 501 through the adjacent hinged rod 502, thereby adjusting the sliding friction of the one-way pulley 503 along the adjacent resistance plate 501.

[0034] See also Figure 8 The limiting assembly includes an insert shaft 506, which is threadedly connected to the adjacent swivel 504. The first piston shaft 9 is provided with an annular array of limiting holes 507, and the annular array of limiting holes 507 are all limitedly matched with the adjacent insert shaft 506. The insert shaft 506 passes through the swivel 504 and enters the adjacent limiting hole 507, thereby locking the adjacent swivel 504 and maintaining the torque of the adjacent fourth elastic element 505 unchanged.

[0035] After the face-fitting airbag 7 and the head-protecting airbag 8 are fixed to the child's head, the staff rotates the two swivels 504 according to the age of the child. The swivels 504 rotate along the adjacent first piston shaft 9, and the swivels 504 drive the adjacent fourth elastic element 505 to twist. The twisted fourth elastic element 505 drives the adjacent one-way pulley 503 to further fit the adjacent resistance plate 501 through the adjacent hinged rod 502, thereby increasing the supporting force of the resistance plate 501 on the adjacent one-way pulley 503, thereby increasing the friction force of the one-way pulley 503 sliding along the resistance plate 501. After the swivel 504 is rotated to the required position, the staff rotates the plug shaft 506 into the swivel 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 swivel 504. At this time, the adjustment is completed, and the fourth elastic element 505 is twisted by the swivel 504, so that the torsional force of the fourth elastic element 505 drives the one-way pulley 503 to further fit the resistance plate 501, thereby increasing the supporting force of the resistance plate 501 on the adjacent one-way pulley 503, and then increasing the friction force of the one-way pulley 503 sliding along the resistance plate 501.

[0036] When the rack 10 drives the adjacent first piston shaft 9 to be pushed inwardly along the gas injection cylinder 6, the first piston shaft 9 pulls the hinge rod 502 thereon to move synchronously, and 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, and the one-way pulley 503 slides frictionally 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 supine to side-lying, thereby inhibiting The child's side-lying movement reduces the probability of the child lying on his side. 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, and the resistance plate 501 squeezes the adjacent one-way pulley 503, so that the one-way pulley 503 drives the adjacent hinged rod 502 to deflect along the adjacent first piston shaft 9, so that the fourth elastic element 505 is further twisted, and then the sliding friction of the one-way pulley 503 along the resistance plate 501 is gradually increased, thereby further inhibiting the child from lying on his side.

[0037] When the first piston shaft 9 is reset along the gas injection cylinder 6, the first piston shaft 9 drives the adjacent hinged rod 502 to reset synchronously, and the hinged rod 502 drives the one-way pulley 503 to reset synchronously. At this time, the one-way pulley 503 can rotate, so that the one-way pulley 503 rotates and moves along the adjacent resistance plate 501 to reset.

[0038] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
