[0008] The movable seat comprises a vertical plate and a bottom plate perpendicular to each other. The soles of the patient's feet abut against the vertical plate. A second air cylinder is arranged on the vertical plate, and the telescopic end of the second air cylinder is rotatably connected to the support pad. The second air cylinder can drive the support pad to slide towards the direction close to the vertical plate.

[0009] A first sliding groove is transversely arranged on the movable seat. A first inserting strip is arranged on the limiting plate. A plurality of clamping grooves are arranged on both sides of the first sliding groove. Spring chucks are arranged on both sides of the first inserting strip. The first inserting strip extends into the first sliding groove, and the spring chucks extend into the clamping grooves to fix the limiting plate on the movable seat.

[0010] The end of the spring chuck is in a triangular structure.

[0011] A second chute is provided on the hospital bed, a second insertion bar is provided at the bottom of the moving seat, the second insertion bar extends into the second chute, a third cylinder is provided on the hospital bed, the telescopic end of the third cylinder is connected to the moving seat, and the third cylinder can push the moving seat to slide.

[0012] An arc-shaped groove is provided on the surface of the support pad, and the patient's ankle is placed on the arc-shaped groove.

[0013] Soft pads are laid on the surfaces of the moving seat, the limiting plate and the support pad close to the patient's foot.

[0014] The number of the anti-foot-drop devices is two.

[0015] By adopting the foregoing technical solutions, the beneficial effects of the present utility model are as follows:

[0016] In the present utility model, the limiting plate can move along the moving seat, which is suitable for people with different foot widths, enabling the two sides of the patient's foot to abut against the limiting plate to prevent the foot from skewing to both sides; the support pad can move, enabling the soles of different patients to more closely abut against the moving seat, having a better anti-foot-drop effect; the support pad can rotate up and down, facilitating the adjustment of the patient's foot posture and being convenient for medical staff to perform inspections, treatments and corrections; at the same time, the moving seat can slide on the hospital bed to prevent the situation that a relatively short patient slides down when the head of the bed is raised; further, when the position of the limiting plate needs to be adjusted, the limiting plate is pushed, and the spring chuck extends into the corresponding card slot to fix the limiting plate, with a simple structure and convenient operation; further, the limiting plate slides more stably on the moving seat through the first chute and the first insertion bar, and the moving seat slides more stably on the hospital bed through the second chute and the second insertion bar; further, the patient's foot can be more stably supported through the arc-shaped groove; further, the soft pad is soft and skin-friendly, improving the comfort of the patient during use.

Specific embodiments

[0025] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] Referring to Figures 1 to 5 , the present utility model provides a foot-drop prevention device, including a hospital bed 5, a moving seat 1 slidably arranged on the hospital bed 5, and two foot-drop prevention devices 2 arranged on the moving seat 1. The foot-drop prevention device 2 includes two limiting plates 21 slidably arranged on the moving seat 1, and a support pad 22 rotatably arranged on the moving seat 1 and located between the two limiting plates 21. The support pad 22 can move between the two limiting plates 21. The sole of the patient abuts against the moving seat 1, and the ankle of the patient is placed on the support pad 22. The limiting plates 21 are located on both sides of the patient's foot. A cavity for placing the heel is formed between the support pad 22 and the two limiting plates 21, so that the patient's heel is suspended. An arc-shaped groove 221 is arranged on the surface of the support pad 22, and the ankle of the patient is placed in the arc-shaped groove 221. Soft pads are laid on one side of the moving seat 1, the limiting plates 21 and the support pad 22 close to the patient's foot.

[0027] The moving seat 1 includes a vertical plate 11 and a bottom plate 12 that are perpendicular to each other. The patient's sole abuts against the vertical plate 11. A first air cylinder 3 is rotatably provided on the bottom plate 12. The telescopic end of the first air cylinder 3 is rotatably connected to the bottom of the support pad 22, and the first air cylinder 3 can drive the support pad 22 to rotate. A second air cylinder 4 is provided on the vertical plate 11. The telescopic end of the second air cylinder 4 is rotatably connected to the support pad 22. When the first air cylinder 3 and the second air cylinder 4 are started simultaneously, they can drive the support pad 22 to slide in the direction close to the vertical plate 11. A first sliding groove 14 is transversely provided on the moving seat 1. A first insertion strip 211 is provided on the limiting plate 21. A plurality of clamping grooves 15 are provided on both sides of the first sliding groove 14. Spring chucks 212 are provided on both sides of the first insertion strip 211. The first insertion strip 211 extends into the first sliding groove 14, and when the spring chucks 212 extend into the clamping grooves 15, the limiting plate 21 can be fixed on the moving seat 1. A second sliding groove 51 is provided on the hospital bed 5. A second insertion strip 16 is provided at the bottom of the moving seat 1. The second insertion strip 16 extends into the second sliding groove 51. A third air cylinder 6 is provided on the hospital bed 5. The telescopic end of the third air cylinder 6 is connected to the moving seat 1, and the third air cylinder 6 can push the moving seat 1 to slide.

[0028] The number of the above anti-foot-drop devices 2 can be one or two, which is specifically set according to the situation.

[0029] The above soft pad can also not be provided, which is specifically set according to the situation.

[0030] The above arc-shaped groove 221 can also not be provided, which is specifically set according to the situation.

[0031] The end of the above spring chuck 212 can be triangular, trapezoidal, arc-shaped or other structures, which is specifically set according to the situation.

[0032] Reference Figure 6 and Figure 7 , the moving seat 1 further includes a sliding plate 13 slidably provided on the bottom plate 12.
