Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a device for preventing foot drop in children while they are in bed. Background Technology

[0002] Foot drop is a common ankle problem that occurs when the ankle joint cannot dorsiflex properly due to weakness in the tibialis anterior muscles or spasm of the triceps surae muscle, resulting in a downward-pointing gait. The main symptoms include difficulty dorsiflexing the ankle, toes pointing downwards during walking, and the toes touching the ground first upon landing. The causes are often related to neuromuscular dysfunction, and may include traumatic brain injury, delayed brain development, spinal cord lesions, prolonged bed rest in severely ill children, or coma. Children who are bedridden for extended periods are prone to foot drop due to lack of activity, which can affect their self-care and mobility after recovery. Currently, common methods for preventing foot drop mainly involve family members massaging the patient's feet or using preventative devices to immobilize the foot and leg to maintain a perpendicular position. These are often fixed and cannot be adjusted to fit the child's foot length, making it difficult to find a suitable device, leading to discomfort or poor effectiveness. Utility Model Content

[0003] The purpose of this invention is to provide a device for preventing foot drop in children while they are in bed. This device is adaptable to different foot lengths, easy to operate, highly flexible, and effectively prevents foot drop. It addresses the technical problem that most existing preventive devices are fixed and cannot be flexibly adjusted to fit the child's foot length.

[0004] To solve the above technical problems, the solution adopted by this utility model is as follows: A device for preventing foot drop in children while in bed includes a stretchable sole, an ankle brace, and an adjustment strap. The ankle brace is fixedly installed on one side of the stretchable sole. The adjustment strap includes adjustment strap A and adjustment strap B, with adjustment strap A connected to the stretchable sole and adjustment strap B connected to the ankle brace. The stretchable sole includes a fixed plate and a stretching plate. The ankle brace is fixedly connected to one side of the fixed plate. Sliding strips are provided on both sides of the stretching plate. The fixed plate has grooves inside that match the sliding strips. The stretching plate is slidably installed inside the fixed plate via the sliding strips and grooves. Untie adjustment straps A and B, place the child's foot against the fixed plate of the stretchable sole, and place the ankle against the ankle brace. Secure the child's foot and ankle with adjustment straps A and B respectively. If the child's foot is long, the stretch plate can be pulled out from the fixed plate to change the length of the stretchable sole to accommodate children with different foot lengths. The curvature of the ankle brace should match the ankle. The adjustment straps are installed at the end of the fixed plate away from the ankle brace.

[0005] Furthermore, the slide bar has several openings; the sliding groove inside the fixed plate has an adjusting block; the adjusting block includes a spring and a trapezoidal block; the trapezoidal block matches the size of the opening; one end of the spring is connected to the middle of the sliding groove, and the other end is fixedly connected to the trapezoidal block. When an external force is applied to pull the stretching plate, the stretching plate stretches outward, compressing the trapezoidal block, which then contracts through the spring, disengages from the current opening, and enters the next opening for size adjustment and positioning. The distance between the openings is designed according to common shoe sizes, allowing the entire stretchable sole to be adjusted from size 16 to size 36, or from 13cm to 23cm.

[0006] Furthermore, the fixing plate is provided with an adjusting turntable; the adjusting turntable passes through the fixing plate and is fixedly connected to the spring; the adjusting turntable is provided with a limiting block; the outside of the fixing plate is provided with an arc-shaped groove that matches the limiting block. When it's necessary to reduce the size or reset the stretchable sole, the adjustment dial can be rotated to rotate the internal trapezoidal block, causing the guide slope of the trapezoidal block to flip. At this time, the guide slope of the trapezoidal block faces away from the ankle support, reducing resistance through the guide slope. External force presses down on the stretch plate, causing the guide slope of the trapezoidal block to slide on the opening. The spring then contracts and disengages from the opening, allowing the stretch plate to retract into the fixed plate. Conversely, when increasing the size and stretching the stretch plate, the adjustment dial is rotated 180 degrees, so that the guide slope of the trapezoidal block faces the ankle support, facilitating the retraction of the trapezoidal block and pulling the stretch plate out of the fixed plate. The arc groove combined with the limiting block ensures that the adjustment dial can only rotate 180 degrees, preventing excessive rotation that could prevent the trapezoidal block from retracting when the stretch plate is pressed down by external force, thus damaging the opening of the stretch plate.

[0007] Furthermore, both the fixing plate and the inner side of the ankle brace are provided with foam. The foam can reduce the pressure between the foot and the device when it is fixed by the adjustment strap, avoiding pressure injury, and can also increase wearing comfort, making the device fit the child's foot and reducing discomfort for the child.

[0008] Furthermore, the adjustment band is equipped with Velcro and adjustment buckles; there are two adjustment bands B, respectively installed at the middle and upper ends of the ankle brace; one end of the stretch plate extends out of the fixing plate, and the extended part is arc-shaped. The Velcro and adjustment buckles can be flexibly adjusted according to the user's leg or foot size to ensure the fit and comfort of the device, while facilitating installation and removal, allowing the device to be quickly put on the patient's foot. The arc-shaped stretch plate can adapt to the curvature of the child's toes, providing even support and pressure distribution.

[0009] The working principle of this utility model is as follows: Based on the child's foot length, pull the stretch plate to disengage the trapezoidal block from the current opening and move it into the next opening. After disengaging from the current opening and fixing the stretch plate in place, adjust the length of the fixing plate and the stretch plate, then position the child's foot on the device. After adjustment, secure the ankle to the ankle brace using the Velcro strap B, and secure the instep to the stretchable sole using the Velcro strap A. If the size of the stretchable sole needs to be reduced, rotate the adjustment dial 180 degrees, causing the internal trapezoidal block to rotate 180 degrees, so that the guide slope of the trapezoidal block faces away from the ankle brace. This allows the stretch plate to press against the trapezoidal block, causing the spring in the trapezoidal block to contract, and thus the stretch plate to retract into the fixing plate. The angle of the trapezoidal block's tip can be adjusted by rotating the adjustment dial forward or backward, facilitating the extension and retraction of the stretch plate, thereby adjusting the length of the stretchable sole.

[0010] The beneficial effects of this utility model are as follows: 1. This utility model uses a stretchable sole with a sliding connection between the stretch plate and the fixed plate to adjust the size of the stretchable sole, adapting to children of different ages and foot lengths, thus improving the versatility and practicality of the device. At the same time, it ensures that the child's feet can receive proper support during long-term bed rest, preventing foot drop. The overall device is highly flexible and easy to use.

[0011] 2. The adjustment strap of this utility model adopts a Velcro design, which can be quickly adjusted according to the size of the child's leg or foot to ensure the fit and comfort of the device. It is also convenient to install and disassemble. The design of the adjustment turntable and adjustment block makes it easy to adjust the size and limit the fixation of the stretchable sole, and avoids the stretch plate from sliding back into the fixed plate.

[0012] 3. The fixing plate and the inner side of the ankle brace of this utility model are provided with foam, which can reduce the pressure between the foot and the device when fixing, avoid pressure injury, and increase the comfort of wearing. Attached Figure Description

[0017] The following is a detailed description of a device for preventing foot drop in children while lying in bed, in conjunction with the accompanying drawings: Example 1

[0018] A device for preventing foot drop in children while in bed includes a stretchable sole 1, an ankle brace 2, and an adjustment strap 3. The ankle brace 2 is fixedly installed on one side of the stretchable sole 1. The adjustment strap 3 includes an adjustment strap A31 and an adjustment strap B32. The adjustment strap A31 is connected to the stretchable sole 1, and the adjustment strap B32 is connected to the ankle brace 2. The stretchable sole 1 includes a fixing plate 4 and a stretching plate 5. The ankle brace 2 is fixedly connected to one side of the fixing plate 4. Sliding strips 6 are provided on both sides of the stretching plate 5. The fixing plate 4 has a sliding groove 7 that matches the sliding strips 6. The stretching plate 5 is slidably installed inside the fixing plate 4 through the sliding strips 6 and the sliding groove 7.

[0019] The working principle of this embodiment is as follows: Based on the child's foot length, pull the stretch plate 5 of the stretchable sole 1 to pull the stretch plate 5 out of the fixed plate 4. After adjusting the length of the fixed plate 4 and the stretch plate 5, place the child's foot on the stretchable sole 1. After adjustment, fix the ankle to the ankle brace 2 by adjusting the Velcro strap B32. Fix the instep to the fixed plate 4 and the stretch plate 5 of the stretchable sole 1 by adjusting the Velcro strap A31. When it is necessary to adjust the size of the stretchable sole 1 to shrink, compress the stretch plate 5 with external force to shrink it into the fixed plate 4, thereby adjusting the length of the stretchable sole 1. Example 2

[0020] The difference from Embodiment 1 is that the slide bar 6 has several openings 8; the sliding groove 7 inside the fixing plate 4 has an adjusting block 8; the adjusting block 8 includes a spring 81 and a trapezoidal block 82; the trapezoidal block 82 matches the size of the opening 11; one end of the spring 81 is connected to the middle of the sliding groove 7, and the other end is fixedly connected to the trapezoidal block 82; the fixing plate 4 has an adjusting turntable 9; the adjusting turntable 9 passes through the fixing plate 4 and is fixedly connected to the spring 81; the adjusting turntable 9 has a limiting block 91; the outside of the fixing plate 4 has an arc-shaped groove 92 that matches the limiting block 91. When an external force is applied to pull the stretching plate 5, the guide slope of the trapezoidal block 82 faces the ankle support direction, making it easy to compress the trapezoidal block 82 and retract it through the spring 81. After disengaging from the current opening 11, it enters the next opening 11 for size adjustment and positioning. Rotating the adjustment turntable 9 rotates the trapezoidal block 82 inside, so that the guide slope of the trapezoidal block 82 faces away from the ankle support direction, making it easy to press the stretching plate 5 with external force, causing the trapezoidal block 82 to disengage from the opening 11. This causes the stretching plate 5 to retract into the fixing plate 4, so that the length of the stretchable sole 1 fits the length of the child's foot. The arc groove 92 combined with the limiting block 91 allows the adjustment turntable 9 to rotate only 180 degrees to avoid excessive rotation.

[0021] The working principle of this embodiment is the same as that of Embodiment 1. Example 3

[0022] The difference from Embodiment 2 is that both the fixing plate 4 and the inner side of the ankle brace 2 are provided with foam 10; the adjusting strap 3 is provided with Velcro; there are two adjusting straps B32, which are respectively installed at the middle and upper ends of the ankle brace 2; one end of the stretching plate 5 extends out of the fixing plate 4, and the extended part is arc-shaped. The foam 10 can reduce the pressure between the foot and the device when fixed by the adjusting strap 3, and the Velcro on the adjusting strap 3 can fix the user's leg and foot to the device, ensuring the fit and comfort of the device, while also facilitating installation and removal.

[0023] The working principle of this embodiment is the same as that of embodiment 2.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
