Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 3A foot fixation device for a comatose patient includes a base 1, a connecting plate 2 fixedly connected to one end of the base 1, a silicone sponge pad 11 fixedly connected to one side of the connecting plate 2, protective pads 3 installed at both ends of the top of the base 1, and snap-fit ​​components 4 provided on both sides of the interior of the base 1. The protective pads 3 are installed on the base 1 through the snap-fit ​​components 4. The snap-fit ​​components 4 include a groove 401, a spring 402, a snap-fit ​​plate 403, a switch plate 404, a slide groove 405, and a slider 406. The groove 401 is opened inside the base 1. Springs 402 are provided at both ends of one side of the inner wall of the groove 401. A snap-fit ​​plate 403 is provided at one end of the spring 402. A switch plate 404 is provided at the bottom of the snap-fit ​​plate 403. Slide grooves 405 are opened on both sides of the inner wall of the groove 401. Slide sliders 406 are provided on both sides of the snap-fit ​​plate 403, and the sliders 406 are located inside the slide grooves 405.

[0028] Place the patient's feet into the space formed by the base 1, connecting plate 2, and protective pad 3. Then, attach the hook and loop fasteners 8 and serrated fasteners 9. In this way, the base 1, connecting plate 2, and protective pad 3 wrap around the patient's feet, which can effectively prevent the feet from touching the foot of the bed and avoid skin abrasion.

[0029] Please see Figures 1 to 4 One end of the spring 402 is fixedly connected to the inner wall of the groove 401, the snap-fit ​​plate 403 is fixedly connected to the other end of the spring 402, the switch plate 404 is fixedly connected to the bottom of the snap-fit ​​plate 403, the slider 406 is fixedly connected to the snap-fit ​​plate 403, the bottom of the protective pad 3 is fixedly connected to the fixing block 5, the fixing block 5 has a snap-fit ​​groove 6 inside, the snap-fit ​​plate 403 is located inside the snap-fit ​​groove 6, the bottom of the base 1 has switch grooves 10 on both sides, and the switch plate 404 is located inside the switch groove 10.

[0030] When the protective pad 3 needs to be disassembled for cleaning, the operator first pulls the switch plate 404, causing it to slide inside the switch slot 10. At the same time, the snap-fit ​​plate 403 moves horizontally, causing the snap-fit ​​plate 403 to retract into the groove 401. The spring 402 is compressed, which increases the distance between the snap-fit ​​plate 403 and the fixing block 5. When the snap-fit ​​plate 403 is completely disengaged from the snap-fit ​​groove 6, the snap-fit ​​relationship between the protective pad 3 and the base 1 is released. Then, the protective pad 3 can be disassembled and cleaned by lifting it upwards. The reverse operation can be performed to reinstall the protective pad 3. The operation is simple and easy to understand. When the snap-fit ​​plate 403 moves, it can drive the slider 406 to slide in the slide groove 405, increasing stability.

[0031] Please see Figure 4 and Figure 5The base 1 has a support assembly 7 on both sides inside, including a movable bar 701, a toothed groove 702, a gear 703, a limiting sleeve 704, a support plate 705, and an electric push rod 706. The movable bar 701 is slidably connected to both sides inside the base 1. A toothed groove 702 is opened on the opposite side of the two movable bars 701. A gear 703 meshes between the two movable bars 701 through the toothed groove 702. A limiting sleeve 704 is sleeved on the surface of the movable bar 701 and is fixedly connected to the base 1. A support plate 705 is fixedly connected to one end of the movable bar 701. An electric push rod 706 is fixedly installed inside the base 1, and the output shaft of the electric push rod 706 is fixedly connected to one side of one of the movable bars 701.

[0032] When the base 1 needs support, the electric push rod 706 is activated, which can push one of the movable bars 701 to move horizontally. In conjunction with the toothed part 702, it can drive the gear 703 to rotate, thereby driving the other movable bar 701 to move in a different direction. This can drive both movable bars 701 to move outward at the same time, thereby driving the two side support plates 705 to move outward, thus effectively supporting the base 1.

[0033] Please see Figures 1 to 2 One of the protective pads 3 is fixedly connected to one side with a barbed hook and loop fastener 8, and the other protective pad 3 is fixedly connected to one side with a rough hook and loop fastener 9.

[0034] The tightness of the protective pad 3 can be adjusted to fit the patient's foot using the hook-and-loop fastener 8 and the loop fastener 9, and can be adjusted according to the patient's foot size.

[0035] In this invention, the working principle of the device is as follows:

[0036] When caring for comatose patients, special attention must be paid to foot care, as preventing the feet from rubbing against the foot of the bed and preventing foot drop are crucial. This foot immobilization device for comatose patients effectively solves these problems.

[0037] The device includes a base 1, with a connecting plate 2 fixedly connected to one end. Protective pads 3 are installed at both ends of the top of the base 1, and are secured by snap-fit ​​components 4 on both sides of the interior. The snap-fit ​​components 4 include a groove 401, a spring 402, a snap-fit ​​plate 403, a switch plate 404, a slide 405, and a slider 406. This design makes it easy to install and remove the protective pads 3, facilitating daily cleaning and replacement.

[0038] In actual use, the patient's feet are placed in the space formed by the base 1, connecting plate 2, and protective pad 3. Then, the hook-and-loop fasteners 8 and hook-and-loop fasteners 9 are attached. In this way, the base 1, connecting plate 2, and protective pad 3 wrap around the patient's feet, effectively preventing the feet from touching the foot of the bed and avoiding skin abrasion. Many comatose patients unconsciously move their feet; without protection, frequent friction between the feet and the foot of the bed can easily cause skin damage and increase the risk of infection. This device minimizes these risks and also performs excellently in preventing foot drop.

[0039] When the patient's foot is secured within the device, its position is effectively controlled and maintained in a functional position. Maintaining the normal foot position is crucial for preventing foot drop; prolonged foot drop can lead to problems such as calf muscle contracture and joint stiffness. This device prevents the foot from dangling uncontrollably, fundamentally reducing the likelihood of foot drop.

[0040] In addition, the device is equipped with a support component 7, which drives the two side support plates 705 to move outward, effectively supporting the base 1 and further ensuring the correct posture of the foot when it is fixed, thus helping to prevent foot drop in all aspects.

[0041] This foot immobilization device, through its ingenious structural design, not only solves the problem of comatose patients' feet rubbing against the foot of the bed, but also plays a significant role in preventing foot drop, providing strong support for foot care for comatose patients, helping to improve the overall quality of care and promote patient recovery.
