Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, specifically relating to a pediatric neck fixation device. Background Technology
[0002] Torticollis in children is a deformity caused by fibrosis and contracture of the sternocleidomastoid muscle, leading to the neck tilting to the affected side and the chin turning to the healthy side. This involves abnormal changes in bones and muscles. Since children's bones are still growing and developing, treatment for torticollis primarily involves using assistive devices for correction. A fixator is strapped to the child's neck to maintain correct neck posture, correct poor posture, and enhance the child's awareness and retention of correct posture.
[0003] Existing fixation devices for pediatric torticollis correction are generally neck-wrapping structures, which tightly encircle the child's neck and often affect neck ventilation. There are also fixation devices that provide unilateral neck support, with an overall L-shaped structure. One end supports the child's shoulder on the affected side, and the other end supports the head. The support angle is adjusted by adjusting the opening angle of the L-shaped aluminum alloy frame to keep the neck in the correct posture. However, because the L-shaped aluminum alloy strip tends to return to its original position after bending, and the child's head may tilt to the affected side during use, the opening angle of the L-shaped aluminum alloy strip may become smaller, causing it to lose its torticollis correction effect. Utility Model Content
[0004] In view of the shortcomings of the existing technology, this utility model proposes a pediatric neck fixation device. The fixation device provides support on one side of the neck, can adjust the correction angle for torticollis, and can easily and stably maintain the correction angle.
[0005] This utility model is achieved through the following technical solution: The device includes two flexible plastic panels, namely an upper flexible plastic panel and a lower flexible plastic panel. Each flexible plastic panel has a soft pad layer fixedly installed on its inner surface. In use, the lower flexible plastic panel is placed on the affected shoulder and the upper flexible plastic panel is attached to the affected head. The system includes two metal strips, namely an upper metal strip and a lower metal strip. The upper metal strip is fixed to the outer surface of the upper flexible plastic sheet, and the lower metal strip is fixed to the outer surface of the lower flexible plastic sheet. The inner ends of the upper metal strip and the lower metal strip are hinged together. The upper and lower metal strips serve as a frame to prevent bending and provide support. It includes a diagonal support rod, which is a telescopic rod structure. Its two ends are respectively hinged to the upper metal strip and the lower metal strip. By adjusting the length of the diagonal support rod, the angle between the upper metal strip and the lower metal strip can be adjusted so that the upper metal strip forms support on the affected side of the head to correct torticollis and prevent the child's neck from tilting to the affected side. It also includes a shoulder and armpit diagonal strap connected to the lower metal plate and a forehead strap connected to the upper flexible plastic plate. When the device is in use, the shoulder and armpit diagonal strap is worn diagonally between the child's shoulder and armpit to fix the lower flexible plastic plate to the child's shoulder, and the forehead strap is wrapped around the child's forehead to fix the upper flexible plastic plate to the child's head. In this way, the device is tied and fixed to the child's neck to maintain the correct neck posture. The device provides support on one side of the neck, has little impact on neck ventilation, and the tilt angle for neck support can be adjusted.
[0006] Furthermore, ear holes are provided in the middle of the upper flexible plastic plate and in the corresponding position on the padding layer on the inner surface of the upper flexible plastic plate. When the fixator is tied and fixed to the child's neck to maintain the correct neck posture, the child's ear on the affected side is located inside the ear hole, avoiding the upper flexible plastic plate and the padding layer from blocking the ear and hindering sound transmission.
[0007] Furthermore, the upper metal strip is fixed to the outer surface of the upper flexible plastic plate by at least two rivets, and the lower metal strip is fixed to the outer surface of the lower flexible plastic plate by at least two rivets, ensuring the overall structural stability.
[0008] Furthermore, the inclined support rod consists of a rotating rod and two sleeve rods; both ends of the rotating rod are provided with external threads, and the helical directions of the external threads at both ends of the rotating rod are opposite. One end of each of the two sleeve rods is provided with an internal thread hole that matches the external threads at both ends of the rotating rod. The ends of the rotating rod are threadedly connected to the sleeve rods. The outer surfaces of the upper metal plate and the lower metal plate are both welded with hinge seats. The other ends of the two sleeve rods are respectively hinged to the two hinge seats. The two ends of the sleeve rods can be simultaneously screwed into or out of the two sleeve rods, thereby adjusting the overall length of the inclined support rod.
[0009] Furthermore, both the distal outer surfaces of the upper and lower flexible plastic plates are provided with two connecting straps, and the connecting straps are provided with buckles. The shoulder and armpit crossbody straps and the forehead straps are Velcro self-adhesive straps. One end of the shoulder and armpit crossbody strap is connected to one of the buckles at the distal end of the lower flexible plastic plate, and the other end can pass through the other buckle at the distal end of the lower flexible plastic plate and be folded back for self-adhesive connection. One end of the forehead strap is connected to one of the buckles at the distal end of the upper flexible plastic plate, and the other end can pass through the other buckle at the distal end of the upper flexible plastic plate and be folded back for self-adhesive connection.
[0010] Furthermore, each of the connecting straps is mounted on the outer surface of the flexible plastic plate by rivets, and the connecting straps can rotate around the rivets, thereby rotating the buckles. When the shoulder straps and forehead straps are tied, the buckles can be rotated to ensure that the shoulder straps and forehead straps can be tied securely and reliably.
[0011] Furthermore, each of the cushion layers has a skin-adhesive layer on its inner surface, and the outer edge of the skin-adhesive layer is attached to the cushion layer with Velcro, which facilitates disassembly, cleaning, or replacement of the skin-adhesive layer.
[0012] As can be seen from the above technical solution, the beneficial effects of the pediatric neck fixation device provided by this utility model are as follows: This fixation device can be used to correct torticollis in children. The shoulder and armpit diagonal strap is worn between the affected shoulder and the healthy armpit to fix the lower flexible plastic plate to the affected shoulder. The forehead strap is wrapped around the child's forehead to fix the upper flexible plastic plate to the child's head. This allows the fixation device to be secured to the child's neck to maintain the correct neck posture. The diagonal support rod is an adjustable telescopic rod structure. By adjusting the length of the diagonal support rod, the opening angle between the upper and lower metal plates can be adjusted, allowing the upper metal plate to drive the upper flexible plastic plate and the child's head to deflect until the child's neck is in the correct posture. This adjusts the tilt angle of the neck support to the correct position. During use, the length of the diagonal support rod is not easily changed, ensuring that the opening angle between the upper and lower metal plates remains stable, which helps the fixation device to continuously and effectively correct torticollis in children. This fixation device provides unilateral neck support, which has less impact on neck ventilation compared to a neck brace structure. The adjustable correction angle of the neck support makes it easy to maintain the correction angle stably. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0020] A pediatric neck immobilizer, such as Figure 1 and Figure 2 As shown, it mainly consists of an upper flexible plastic plate 1, an upper metal strip plate 2, a lower flexible plastic plate 3, a lower metal strip plate 4, a shoulder and armpit diagonal strap 5, a diagonal support rod 7, a soft padding layer 9, and a forehead strap 11.
[0021] like Figure 1 As shown, the inner surfaces of the upper flexible plastic plate 1 and the lower flexible plastic plate 3 are both fixedly provided with a soft pad layer 9. When in use, the lower flexible plastic plate 3 is placed on the affected shoulder and the upper flexible plastic plate 1 is attached to the affected head. Both the upper flexible plastic plate 1 and the lower flexible plastic plate 3 are made of PP plastic sheet. like Figure 1 As shown, each padding layer 9 has a skin-adhesive layer 10 on its inner surface. The outer edge of the skin-adhesive layer 10 is attached to the padding layer 9 by Velcro, which makes it easy to remove, clean or replace the skin-adhesive layer 10. Specifically, the padding layer 9 is composed of a cotton core (or a sponge core) and the fabric wrapped around it. The skin-adhesive layer 10 is made of cotton fleece fabric (suitable for autumn and winter), soft towel fabric (suitable for autumn and winter), or ice silk fabric (suitable for spring and summer).
[0022] like Figure 1 and Figure 2 As shown, both ends of the upper metal strip 2 are fixed to the outer surface of the upper flexible plastic plate 1 by rivets 6, and both ends of the lower metal strip 4 are fixed to the outer surface of the lower flexible plastic plate 3 by rivets 6. The inner ends of the upper metal strip 2 and the lower metal strip 4 are hinged to ensure the overall structural stability. The upper metal strip 2 and the lower metal strip 4 act as a skeleton to prevent bending and provide support. In the above structure, the side closer to the skin is the inner surface, and the end that is close to both is the inner end. like Figure 1 and Figure 2As shown, the inclined support rod 7 is a telescopic rod structure, with its two ends hinged to the upper metal strip 2 and the lower metal strip 4 respectively. By adjusting the length of the inclined support rod 7, the included angle between the upper metal strip 2 and the lower metal strip 4 can be adjusted, so that the upper metal strip 2 forms a support on the affected side of the head to correct torticollis and prevent the child's neck from tilting to the affected side. Specifically, the upper metal strip 2, the lower metal strip 4 and the inclined support rod 7 are all made of stainless steel or aluminum alloy.
[0023] like Figure 1 and Figure 2 As shown, two connecting straps 15 are provided on the distal outer surface of the upper flexible plastic plate 1 and the distal outer surface of the lower flexible plastic plate 3, and the connecting straps 15 are provided with buckles 12. The shoulder and armpit diagonal straps 5 and the forehead straps 11 are both Velcro self-adhesive straps. One end of the shoulder and armpit diagonal straps 5 is connected to one of the buckles 12 at the distal end of the lower flexible plastic plate 3, and the other end can pass through the other buckle 12 at the distal end of the lower flexible plastic plate 3 and be folded back for self-adhesive connection. One end of the forehead straps 11 is connected to one of the buckles 12 at the distal end of the upper flexible plastic plate 1, and the other end can pass through the other buckle 12 at the distal end of the upper flexible plastic plate 1 and be folded back for self-adhesive connection. Specifically, such as Figure 2 As shown, the far end of the upper flexible plastic plate 1 and the far end of the lower flexible plastic plate 3 refer to the ends that are far apart from each other. The two connecting straps 15 are located on both sides of the metal strip. One end of the shoulder and armpit diagonal strap 5 is sewn onto one of the loops 12 at the far end of the lower flexible plastic plate 3, and the outer surface of its other end is provided with a Velcro surface 13 and a Velcro hook surface 14. One end of the forehead strap 11 is sewn onto one of the loops 12 at the far end of the upper flexible plastic plate 1, and the outer surface of its other end is provided with a Velcro surface 13 and a Velcro hook surface 14. like Figure 2 As shown, each of the connecting straps 15 is mounted on the outer surface of the flexible plastic plate by a rivet 6, and the connecting strap 15 can rotate around the rivet 6, thereby rotating the buckle 12. When the shoulder and armpit crossbody straps 5 and the forehead straps 11 are tied, the buckle 12 can be rotated to ensure that the shoulder and armpit crossbody straps 5 and the forehead straps 11 can be tied securely and reliably.
[0024] As a preferred embodiment, in this example, Figure 2 As shown, ear holes 16 are provided in the middle of the upper flexible plastic plate 1 and on the corresponding positions of the padding layer 9 and the skin-adhesive layer 10 on the inner surface of the upper flexible plastic plate 1. When the fixation device is tied and fixed to the child's neck to maintain the correct neck posture, the child's ear on the affected side is located inside the ear hole 16, so as to avoid the upper flexible plastic plate 1 and the padding layer 9 from blocking the ear and obstructing the sound transmission.
[0025] As a preferred embodiment, in this example, Figure 1 and Figure 2As shown, the inclined support rod 7 consists of a rotating rod 7.1 and two sleeve rods 7.2. Both ends of the rotating rod 7.1 are provided with external threads, and the helical directions of the external threads at both ends of the rotating rod 7.1 are opposite. One end of each of the two sleeve rods 7.2 is provided with an internal thread hole that matches the external threads at both ends of the rotating rod 7.1. The end of the rotating rod 7.1 is threadedly connected to the sleeve rod 7.2. The outer surface of the upper metal strip 2 and the outer surface of the lower metal strip 4 are both welded with hinge seats 8. The other ends of the two sleeve rods 7.2 are respectively hinged to the two hinge seats 8. The two ends of the sleeve rods 7.2 can be simultaneously screwed into or out of the two sleeve rods 7.2, thereby adjusting the overall length of the inclined support rod 7. In addition, such as Figure 3 As shown, the diagonal support rod 7 can also be composed of an inner insert plate 7.3, an outer sleeve plate 7.4, and a locking bolt 7.5. One end of the inner insert plate 7.3 is inserted into the interior of one end of the outer sleeve plate 7.4. The locking bolt 7.5 is threaded onto one end of the outer sleeve plate 7.4 and can be used to lock the inner insert plate 7.3. The other end of the inner insert plate 7.3 and the other end of the outer sleeve plate 7.4 are respectively hinged to two hinge seats 8. When it is necessary to adjust the overall length of the diagonal support rod 7, loosen the locking bolt 7.5 to allow the inner insert plate 7.3 to move in and out of the outer sleeve plate 7.4 to adjust the length of the overlapping section, and then tighten the locking bolt 7.5. With this structure, it is essential to ensure that the locking bolt 7.5 is tightened to prevent the length of the diagonal support rod 7 from changing during use due to the locking bolt 7.5 failing to lock the inner insert plate 7.3.
[0026] The working principle of this embodiment: When using this fixation device, the lower flexible plastic plate 3 is placed on the affected shoulder of the child, and the upper flexible plastic plate 1 is placed against the head on the affected side. The movable end of the shoulder and armpit diagonal strap 5 passes over the child's chest, under the healthy armpit, and behind the back, then passes through the loop 12 on the back of the lower flexible plastic plate 3 and is folded back for self-adhesion. The movable end of the forehead strap 11 passes over the child's forehead, wraps around the head, then passes through the loop 12 on the back of the upper flexible plastic plate 1 and is folded back for self-adhesion. During the binding process of the shoulder and armpit diagonal strap 5 and the forehead strap 11, they are coordinated to ensure that the fixation device is firmly bound and fixed to the neck on the affected side of the child. With unilateral support, this fixation device has less impact on neck ventilation compared to a neck brace-style support structure. Twisting the rotating rod 7.1 adjusts the opening angle between the upper metal strip 2 and the lower metal strip 4. The upper metal strip 2 causes the upper flexible plastic plate 1 and the child's head to deflect until the child's neck is in the correct posture. This adjusts the tilt angle of the neck support to the correct position. During the child's use, the length of the diagonal support rod 7 is not easily changed, making it less likely for the opening angle between the upper metal strip 2 and the lower metal strip 4 to change. This helps the fixation device to continuously and effectively correct the child's torticollis.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
