Technical Field

[0001] This utility model relates to the field of human daily necessities, and more particularly to medical assistive devices, especially a support frame for preventing foot drop. Background Technology

[0002] Foot drop refers to the inability to dorsiflex the ankle joint due to factors such as weak tibialis anterior muscles, triceps surae spasm, or Achilles tendon spasm. Current methods for preventing foot drop include wearing foot supports, insoles, and shoes to maintain the foot's functional position and prevent bone and joint deformities.

[0003] However, for the skin of elderly, long-term bedridden, and critically ill patients, the use of these instruments can easily cause pressure injuries at bony prominences of the feet due to the material properties. Furthermore, their use in bed makes it inconvenient to observe skin pressure. To avoid prolonged pressure on the skin, foam dressings are typically used to protect it, which increases the cost of patient care supplies. Summary of the Invention

[0004] The purpose of this invention is to provide a support frame for preventing foot drop, which solves the technical problems of existing foot drop prevention devices that easily cause pressure injuries and make it difficult to observe the pressure on the skin.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this does not limit the present invention.

[0022] Example 1

[0023] like Figures 1-4 As shown, a support frame for preventing foot drop according to this utility model includes a horizontally arranged heel support plate 1, a foot support plate 2 vertically fixed to the upper rear end of the heel support plate 1, a heel memory foam pad 3 on the upper side of the heel support plate 1, a support leg 5 on the rear side of the foot support plate 2, and a foot memory foam pad 4 on the front side of the foot support plate 2. The front side of the foot memory foam pad 4 has two recessed parts 41 spaced apart.

[0024] Specifically, the heel support plate 1 is placed horizontally on the hospital bed, and the support leg 5 is supported on the front side of the foot support plate 2 so that the foot support plate 2 can be stably erected. The heel support plate 1 and the heel memory foam pad 3 can cushion the Achilles tendon area, and the foot support plate 2 and the foot memory foam pad 4 can support the foot surface, so that the foot and the lower leg are perpendicular to the horizontal plane. The foot is embedded in the concave part 41 of the foot memory foam pad 4 to maintain the normal functional position of the foot, which can effectively prevent foot drop and reduce the occurrence of pressure injury.

[0025] Furthermore, the heel memory foam pad 3 is fixed to the upper side of the heel support plate 1 by Velcro 6.

[0026] Specifically, the heel memory foam pad 3 is fixed by Velcro 6, and the front and back positions of the heel memory foam pad 3 can be adjusted within the adhesive range of Velcro 6. The heel memory foam pad 3 can also be replaced, making it easy to disassemble, clean, and disinfect.

[0027] Furthermore, the cross-section of the heel memory foam pad 3 is semi-teardrop shaped.

[0028] Specifically, the semi-teardrop-shaped protrusion can be positioned on the side away from the foot support plate 2, so that the protrusion can better cushion the Achilles tendon, avoid direct pressure contact with the heel, and reduce the occurrence of pressure injuries.

[0029] Furthermore, the cross-section of the recessed portion 41 is semi-circular.

[0030] Specifically, the semi-circular shape can conform to the sole of the foot, avoiding pressure contact at the bony prominence and reducing the occurrence of pressure injuries.

[0031] Furthermore, there are four supporting legs 5, which are arranged in a rectangular pattern on the rear side of the foot support plate 2.

[0032] Specifically, the four support legs 5 are arranged in a rectangular shape and support the front side of the bed foot support plate 2, which can stably support the foot support plate 2 and prevent the foot support plate 2 from moving back and forth or rotating.
