The friction between the rolling shaft and the bottom of the leg accelerates blood flow to the bottom of the leg, reducing the formation of pressure sores. It also helps patients rotate their ankles, preventing muscle atrophy and ankle stiffness caused by prolonged immobility of the legs and feet, thus facilitating subsequent rehabilitation and walking.

Description

Technical Field

[0001] This utility model relates to the technical field of foot fixation devices, and more specifically, to a foot fixation device for preventing pressure sores. Background Technology

[0002] Foot immobilization devices are assistive medical devices designed to prevent and reduce foot pressure sores caused by prolonged bed rest or wheelchair use. These devices reduce the risk of pressure sores by distributing pressure, reducing continuous pressure on specific areas of the foot, and promoting blood circulation.

[0003] There are many existing technologies for foot immobilization devices, such as:

[0004] Chinese patent application number 202121310292.0 discloses a sock tube and a protective component. The sock tube has an opening at the rear end and includes a tube body and a heel area, the heel area being an outwardly convex arc shape. The protective component is disposed in the heel area and includes a first protective pad, a second protective pad, and a protective spring. One side of the first protective pad is adhered to the outer side of the heel area. One end of the protective spring is connected to the first protective pad, and the other end is connected to the second protective pad. The protective spring is also connected to the outer peripheral edge of the first protective pad. The shape and size of the first protective pad match the heel area. This foot fixation device for preventing pressure ulcers, by wearing the sock tube, positions the protective component at the bottom of the heel, ensuring reliable fixation. Due to the pressure of the weight of the heel, the protective spring contracts, generating an upward force that provides soft support to the heel, preventing direct contact between the heel and the bed, thus avoiding pressure ulcers.

[0005] However, when using foot immobilization devices to prevent pressure sores, the device remains in constant contact with the leg, causing prolonged pressure on the local skin, affecting blood circulation, and easily leading to pressure sores. Furthermore, immobility of the patient's feet can cause muscle atrophy and ankle stiffness, which is not conducive to subsequent rehabilitation. Therefore, we propose a foot immobilization device to prevent pressure sores. Utility Model Content

[0006] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a foot fixation device to prevent pressure sores;

[0007] To achieve the above objectives, this utility model provides a foot fixation device for preventing pressure sores, comprising a U-shaped plate, a strap fixedly connected to the top of the U-shaped plate, a rotating shaft rotatably connected inside the U-shaped plate, a rotating plate fixedly connected to the outer left side of the rotating shaft, fixing ropes fixedly connected to the outer left and right sides of the rotating plate, a fixing plate fixedly connected to the inner surface of the U-shaped plate, an end of a telescopic rod fixedly connected to the bottom of the inner surface of the fixing plate, a spring sleeved on the outside of the telescopic rod, an end of the spring fixedly connected to the bottom of the inner surface of the fixing plate, a mounting plate fixedly connected to the other end of the telescopic rod and the spring, and a rolling shaft end rotatably connected to the inner left and right sides of the mounting plate;

[0008] The rotating plate rotates on the rotating shaft in the direction of rotation.

[0009] As a further improvement to this technical solution, a slot is provided on the outer surface of the rotating shaft near the middle end, and the end of a U-shaped block is inserted into the slot. The outer surface of the other end of the U-shaped block is inserted into the U-shaped plate.

[0010] As a further improvement to this technical solution, a rotating handle is fixedly connected to the end of the rotating shaft.

[0011] As a further improvement to this technical solution, a rectangular plate is fixedly connected to the back of the U-shaped plate, and a threaded rod is threadedly connected inside the rectangular plate, with a turning handle fixedly connected to the end of the threaded rod.

[0012] As a further improvement to this technical solution, the other end of the threaded rod is rotatably connected to a support plate, the top of the support plate is fixedly connected to the end of a sliding rod, and the outer surface of the sliding rod is slidably connected to the inside of the rectangular plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] First, turning the handle rotates the shaft, which in turn rotates the plate. Then, the spring rebounds, causing the mounting plate to move up and down. This movement of the mounting plate causes the rolling shaft to move up and down, keeping it close to the bottom of the leg. As the plate rotates, the bottom of the leg rubs against the rolling shaft, causing it to rotate. This friction between the rolling shaft and the bottom of the leg accelerates blood flow, reduces pressure sores, and helps patients rotate their ankles. This prevents muscle atrophy and ankle stiffness caused by prolonged immobility of the legs and feet, facilitating subsequent rehabilitation and walking. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Foot immobilization devices are assistive medical devices designed to prevent and reduce foot pressure sores caused by prolonged bed rest or wheelchair use. These devices reduce the risk of pressure sores by distributing pressure, reducing continuous pressure on specific areas of the foot, and promoting blood circulation.

[0026] Please see Figures 1-5As shown, this embodiment provides a foot fixation device to prevent pressure sores, including a U-shaped plate 1. To ensure blood circulation in the foot, the device is specifically designed as follows: a strap 11 is fixedly connected to the top of the U-shaped plate 1; a rotating shaft 22 is rotatably connected inside the U-shaped plate 1; a rotating plate 2 is fixedly connected to the outer left side of the rotating shaft 22; fixing ropes 21 are fixedly connected to the outer left and right sides of the rotating plate 2; a fixing plate 24 is fixedly connected to the inner surface of the U-shaped plate 1; and the end of a telescopic rod 241 is fixedly connected to the bottom of the inner surface of the fixing plate 24. A spring 242 is sleeved on the outside of the telescopic rod 241. The end of the spring 242 is fixedly connected to the bottom of the inner surface of the fixing plate 24. The other end of the telescopic rod 241 and the spring 242 are fixedly connected to the mounting plate 25. The ends of the rolling shaft 26 are rotatably connected to the inner surfaces of the left and right sides of the mounting plate 25. The rotating plate 2 rotates on the rotating shaft 22 in the direction of rotation. However, in the process of using the foot fixation device for preventing pressure sores, the foot fixation device is always in contact with the leg, which causes the local skin to be under pressure for a long time, affecting blood circulation and easily causing pressure sores. Moreover, the patient's feet are not moving, which can easily cause muscle atrophy and ankle stiffness, which is not conducive to subsequent rehabilitation.

[0027] The improvement in this embodiment is as follows:

[0028] First, rotating handle 222 causes shaft 22 to rotate, which in turn causes rotating plate 2 to rotate. Then, spring 242 rebounds and causes mounting plate 25 to move up and down. The up and down movement of mounting plate 25 causes rolling shaft 26 to move up and down, closely adhering to the bottom of the leg. When rotating plate 2 rotates, the bottom of the leg rubs against rolling shaft 26, causing rolling shaft 26 to rotate. The friction between rolling shaft 26 and the bottom of the leg accelerates blood flow to the bottom of the leg, reduces the formation of pressure sores, and helps patients rotate their ankles, avoiding muscle atrophy and ankle stiffness caused by prolonged immobility of the legs and feet, which is beneficial for subsequent rehabilitation and walking.

[0029] To prevent the rotating shaft 22 from rotating randomly, a slot 221 is provided on the outer surface of the rotating shaft 22 near the middle end. The end of a U-shaped block 23 is inserted into the slot 221, and the outer surface of the other end of the U-shaped block 23 is inserted into the U-shaped plate 1. First, the U-shaped plate 1 fixes the U-shaped block 23, and then the U-shaped block 23 fixes the rotating shaft 22, so that the rotating shaft 22 does not rotate randomly.

[0030] To facilitate the rotation of the shaft 22, a rotating handle 222 is fixedly connected to the end of the shaft 22. First, rotating the handle 222 will drive the shaft 22 to rotate, thus facilitating the rotation of the shaft 22.

[0031] Secondly, in order to make the foot tilt more comfortable, a rectangular plate 31 is fixedly connected to the back of the U-shaped plate 1. A threaded rod 32 is threaded inside the rectangular plate 31. A turning handle 33 is fixedly connected to the end of the threaded rod 32. First, there are two threaded rods 32. Then, turning the handle 33 rotates the threaded rod 32 to move it up and down, so that the foot can tilt left and right more comfortably.

[0032] Considering that the threaded rod 32 is too small and unstable, a support plate 3 is rotatably connected to the other end of the threaded rod 32. The top of the support plate 3 is fixedly connected to the end of the slide rod 34. The outer surface of the slide rod 34 is slidably connected to the inside of the rectangular plate 31. With the support plate 3, a larger area and greater stability are achieved.

[0033] In summary, the working principle of this solution is as follows:

[0034] Place your foot on the rolling roller 26, ensuring the sole is firmly against the rotating plate 2. Manually tie the fixing rope 21, ensuring the foot and rope are in contact. Then manually tie the strap 11, ensuring the bottom of the leg is in contact with the rolling roller 26. Manually remove the U-shaped block 23 and manually turn the handle 222. Turning the handle 222 rotates the rotating roller 22, which in turn rotates the rotating plate 2, which in turn rotates the foot. The angle of rotation can be adjusted according to the patient's foot condition, rotating in an arc. As the rotating plate 2 rotates, the bottom of the leg rubs against the rolling roller 26, causing the roller 26 to rotate. This friction between the rolling roller 26 and the bottom of the leg accelerates blood flow and reduces pressure sores. Alternatively, the fixing rope 21 can be untied, and the rotating plate 2 can be rotated below the rolling roller 26. Holding the U-shaped plate 1, the rolling roller 26... The patient's entire lower leg is rubbed back and forth to massage the lower leg, promoting blood flow and preventing pressure sores. When the patient is not exercising, the fixing rope 21 is tied to the patient's foot again, allowing the rotating plate 2 to rotate to a comfortable angle for the patient. The U-shaped block 23 is inserted into the slot 221 and the U-shaped plate 1. Since some patients are more comfortable with their legs tilted, the handle 33 is manually turned. The rotation of the handle 33 drives the threaded rod 32 to move up and down, which in turn drives the support plate 3 to move up and down. When the two support plates 3 are at different heights, the foot will tilt. This allows the foot to tilt and the height to be adjusted according to the patient's comfort. It can be fixed to both the foot and the leg, preventing long-term pressure on one area and the development of pressure sores. It also helps the patient rotate their foot, preventing ankle stiffness and facilitating subsequent rehabilitation and walking, making the patient more comfortable.
