Abstract
Description
Technical Field
[0001] This utility model relates to the field of protective gear technology, and more specifically, to a protective gear for preventing foot drop. Background Technology
[0002] Foot drop is a condition caused by neurological or muscular problems that prevent the ankle from dorsiflexing, resulting in a drooping foot. Causes include traumatic nerve injury, compressive nerve injury, neurological disorders, and muscle diseases or injuries. This condition severely affects motor function, making walking difficult, increasing the risk of falls, increasing energy expenditure, negatively impacting quality of life, reducing self-care ability, and potentially leading to psychological problems. Therefore, foot drop braces are particularly important. They serve as functional recovery aids, providing support and assistance to the ankle joint when nerve or muscle function is impaired, maintaining the foot's normal position, preventing complications such as Achilles tendon contracture, improving walking safety, reducing the risk of tripping and falling due to foot drop, and ensuring the smooth progress of rehabilitation training.
[0003] There are many types of foot drop braces available, but they still have the following shortcomings when used: 1. Foot drop braces can easily cause pressure sores on the patient's heel when used for a long time; 2. Foot drop braces usually use an angle adjustment strap to pull and drive the outer shell to deform to adapt to the human ankle joint, which affects the service life of the outer shell. In addition, the wear and tear of the angle adjustment strap after long-term use reduces the adjustment function and makes it impossible to always maintain the adjusted shape of the outer shell.
[0004] Therefore, there is an urgent need for a foot drop protection device to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a foot drop protection device to solve the problems mentioned in the background art.
[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:
[0007] A foot drop prevention brace includes an outer shell, with evenly distributed fixing straps fixedly connected to the outer wall of the outer shell, and a female buckle fixedly connected to the end of each fixing strap away from the outer shell. The brace also includes:
[0008] The mounting slot is formed on the inner wall of the outer casing;
[0009] A protective component, comprising a thermoplastic shell disposed on the inner wall of an installation groove, a water bladder fixedly connected to the outer wall of the thermoplastic shell, symmetrically distributed sealing zipper strips on the outer wall of the water bladder, and sealing zipper heads on the outer wall of the sealing zipper strips;
[0010] A compression fitting component is disposed on the outer wall of the housing, and the compression fitting component cooperates with the protective component;
[0011] An angle adjustment component is located on the inner wall of the outer casing.
[0012] As a preferred technical solution of this application, the extrusion and bonding assembly includes an extrusion screw symmetrically threaded to the outer wall of the outer shell, an extrusion block rotatably connected to the outer wall of the extrusion screw, and the end of the extrusion block away from the extrusion screw abutting against the outer wall of the thermoplastic shell, and a rotating knob fixedly connected to the end of the extrusion screw away from the extrusion block.
[0013] As a preferred technical solution of this application, the angle adjustment assembly includes a base plate fixedly connected to the inner wall of the outer shell, an adjustment screw rotatably connected to the inner wall of the base plate, a slider threadedly connected to the outer wall of the adjustment screw, a slide block fixedly connected to the top wall of the base plate, and the slide block slidably connected to the slider, an adjustment knob fixedly connected to the outer wall of the adjustment screw, a push plate fixedly connected to the outer wall of the slider, and a linkage rod fixedly connected to the end of the push plate away from the slider.
[0014] As a preferred technical solution of this application, the outer wall of the linkage rod is rotatably connected to a symmetrically distributed connecting seat, the top wall of the connecting seat is fixedly connected to an inner liner, and the outer wall of the inner liner abuts against the outer wall of the water bladder, and the outer wall of the inner liner is provided with uniformly distributed honeycomb holes.
[0015] As a preferred technical solution of this application, the outer wall of the outer shell is fixedly connected with a uniformly distributed adjustment belt, and a sub-buckle is fixedly connected to the end of the adjustment belt away from the outer shell, and the sub-buckle and the female buckle are detachably connected.
[0016] As a preferred technical solution of this application, the outer wall of the outer shell is fixedly connected with symmetrically distributed elastic bands.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] In the scheme of this application:
[0019] 1. The water bladder is placed in the mounting groove, and the extrusion block is driven to move by the threaded engagement between the extrusion screw and the outer shell, thereby pushing the water bladder and the inner lining to fit tightly against the ankle. The water bladder can adaptively change shape according to the shape of the ankle and heel, so as not to generate excessive pressure points in a local area. Moreover, the water in the water bladder will flow according to the magnitude and direction of the pressure when a person walks, absorbing and dispersing these pressures, buffering the extra pressure on the heel, and solving the problem that pressure sores are easily caused on the heel of patients when foot drop braces are used for a long time in the existing technology.
[0020] 2. The sliding block is driven to slide on the slide block by the threaded engagement between the adjusting screw and the slider, and then the inner liner is pushed by the push plate to adjust the angle. This avoids deformation and wear of the outer shell, and prevents the service life of the outer shell from being affected. The adjustment by rotating the screw can more accurately adjust the protective gear to adapt to the angle of the human body and make it more secure during walking. It helps the protective gear maintain the adjusted angle for a long time and is more helpful in the prevention and treatment of foot drop. This solves the problem that the existing foot drop protective gear usually uses the angle adjustment belt to pull and drive the outer shell to deform to adapt to the human ankle joint, which affects the service life of the outer shell. In addition, the wear of the angle adjustment belt after long-term use reduces the adjustment function and makes it impossible to always maintain the adjusted shape of the outer shell.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.
[0031] Example 1:
[0032] like Figure 1-7 As shown, the present embodiment of the anti-foot drop brace includes an outer shell 1, with uniformly distributed fixing straps 2 fixedly connected to the outer wall of the outer shell 1, and a female buckle 4 fixedly connected to the end of the fixing straps 2 away from the outer shell 1. It also includes:
[0033] Mounting slot 7 is formed on the inner wall of outer casing 1;
[0034] The protective component includes a thermoplastic shell 17 disposed on the inner wall of the mounting groove 7. A water bladder 21 is fixedly connected to the outer wall of the thermoplastic shell 17. The outer wall of the water bladder 21 is provided with symmetrically distributed sealing zipper straps 22, and the outer wall of the sealing zipper straps 22 is provided with sealing zipper heads 23. The function of the water bladder 21 is to provide cushioning and pressure relief for the heel and ankle. The symmetrically distributed sealing zipper straps 22 and sealing zipper heads 23 on its outer wall facilitate the filling or maintenance of the water bladder 21. When the patient wears the protective gear, the water bladder 21 can fit the ankle and heel, using the fluidity and elasticity of water to disperse pressure, reduce the risk of pressure sores caused by local pressure concentration, and at the same time play a cushioning and protective role for the joints during the patient's activities.
[0035] A compression fitting component is disposed on the outer wall of the housing 1, and the compression fitting component cooperates with the protective component;
[0036] An angle adjustment component is located on the inner wall of the outer casing 1.
[0037] like Figure 6 As shown, in a preferred embodiment, based on the above method, the compression fitting component further includes a compression screw 18 symmetrically threaded to the outer wall of the outer shell 1. A compression block 20 is rotatably connected to the outer wall of the compression screw 18, and the end of the compression block 20 away from the compression screw 18 abuts against the outer wall of the thermoplastic shell 17. A rotating knob 19 is fixedly connected to the end of the compression screw 18 away from the compression block 20. The compression screw 18 symmetrically threaded to the outer wall of the outer shell 1 can be rotated by rotating the rotating knob 19 at one end. Since the compression screw 18 is threaded to the outer shell 1, when the compression screw 18 rotates, it will drive the compression block 20 rotatably connected to its outer wall to move, so that the compression block 20 is squeezed towards the thermoplastic shell 17. In this way, the tightness of the fit between the water bag 21 and the ankle and heel can be adjusted as needed, ensuring that the water bag 21 can better play the role of cushioning and pressure relief, and further optimize the protection of the ankle and heel.
[0038] Example 2:
[0039] like Figure 4 As shown, in a preferred embodiment, based on the above method, the angle adjustment assembly further includes a base plate 8 fixedly connected to the inner wall of the outer casing 1. An adjusting screw 9 is rotatably connected to the inner wall of the base plate 8. A slider 11 is threadedly connected to the outer wall of the adjusting screw 9. A slide block 15 is fixedly connected to the top wall of the base plate 8, and the slide block 15 is slidably connected to the slider 11. An adjusting knob 10 is fixedly connected to the outer wall of the adjusting screw 9. A push plate 12 is fixedly connected to the outer wall of the slider 11. A linkage rod 13 is fixedly connected to the end of the push plate 12 away from the slider 11. Rotating the adjusting screw 9... The knob 10 allows the slider 11, which is threadedly connected to the adjusting screw 9, to slide on the slide block 15, which is fixedly connected to the top wall of the base plate 8. The movement of the slider 11 drives the push plate 12 to move. The push plate 12 transmits force to the inner liner 16 through the linkage rod 13 and the connecting seat 14, thereby changing the angle of the inner liner 16. The bottom of the inner liner 16 is a rigid structure, which serves as a support for the human foot. This threaded adjustment method can achieve relatively precise angle adjustment, and due to the self-locking property of the thread, it can stably maintain the adjusted angle, providing a suitable support angle for the ankle joint.
[0040] like Figure 3 As shown, in a preferred embodiment, based on the above method, the outer wall of the linkage rod 13 is further rotatably connected to symmetrically distributed connecting seats 14, the top wall of the connecting seat 14 is fixedly connected to an inner liner 16, and the outer wall of the inner liner 16 abuts against the outer wall of the water bag 21. The outer wall of the inner liner 16 is provided with uniformly distributed honeycomb holes 24. The honeycomb hole 24 structure can increase the breathability and softness of the inner liner 16, and improve the comfort of the patient wearing it.
[0041] like Figure 1-2 As shown, in a preferred embodiment, based on the above method, the outer wall of the outer shell 1 is further provided with a uniformly distributed adjustment strap 3. The end of the adjustment strap 3 away from the outer shell 1 is fixedly connected with a sub-buckle 5, and the sub-buckle 5 is detachably connected to the female buckle 4. The protective gear is worn and fixed by the uniformly distributed fixing strap 2 and the adjustment strap 3 fixedly connected to the outer wall of the outer shell 1. The female buckle 4 at one end of the fixing strap 2 and the sub-buckle 5 at one end of the adjustment strap 3 are detachably connected, and the tightness can be adjusted according to the thickness of the patient's legs to fix the protective gear on the legs.
[0042] like Figure 1As shown, in a preferred embodiment, based on the above method, the outer wall of the outer shell 1 is further provided with symmetrically distributed elastic bands 6. The symmetrically distributed elastic bands 6 fixedly connected to the outer wall of the outer shell 1 also help to enhance the fixation effect of the protective gear and adapt to the movement of the legs and the contraction and relaxation of muscles to a certain extent.
[0043] Specifically, when using this foot drop prevention brace: the brace is worn and secured by evenly distributed fixing straps 2 and adjusting straps 3 fixedly connected to the outer wall of the outer shell 1. The female buckle 4 at one end of the fixing strap 2 and the female buckle 5 at one end of the adjusting strap 3 are detachably connected, allowing adjustment of the tightness according to the patient's leg size, thus securing the brace to the leg. Simultaneously, the symmetrically distributed elastic straps 6 fixedly connected to the outer wall of the outer shell 1 also help enhance the brace's fixation effect and, to a certain extent, adapt to leg movements and muscle contraction and relaxation, maintaining a relatively stable position; the water bladder 2... The function of 1 is to provide cushioning and pressure relief for areas such as the heel and ankle. Its outer wall is equipped with symmetrically distributed sealed zipper straps 22 and sealed zipper heads 23, which facilitates operations such as filling or maintaining the water bladder 21. When the patient wears the protective gear, the water bladder 21 can fit the ankle and heel, using the fluidity and elasticity of water to disperse pressure and reduce the risk of pressure sores caused by local pressure concentration. At the same time, it plays a cushioning and protective role for the joints during the patient's activities. The compression screw 18 is symmetrically threaded to the outer wall of the outer shell 1. By turning the rotation knob 19 at one end, the compression screw 18 can be rotated. Since the extrusion screw 18 is threadedly connected to the outer shell 1, when the extrusion screw 18 rotates, it will drive the extrusion block 20 connected to its outer wall to move, so that the extrusion block 20 is extruded towards the thermoplastic shell 17. This allows the tightness of the fit between the water bladder 21 and the ankle and heel to be adjusted as needed, ensuring that the water bladder 21 can better play its cushioning and pressure-reducing role, and further optimize the protection of the ankle and heel. Rotating the adjustment knob 10 on the adjustment screw 9 allows the slider 11, which is threadedly connected to the adjustment screw 9, to slide on the slide block 15 fixedly connected to the top wall of the base plate 8. The movement of the slider 11 drives the push plate 1 2. During movement, the push plate 12 transmits force to the inner liner 16 through the linkage rod 13 and the connecting seat 14, thereby changing the angle of the inner liner 16. The bottom of the inner liner 16 is a rigid structure, which serves as a support for the human foot. This threaded adjustment method can achieve relatively precise angle adjustment, and due to the self-locking property of the thread, it can stably maintain the adjusted angle, providing a suitable support angle for the ankle joint. The outer wall of the inner liner 16 is provided with evenly distributed honeycomb holes 24. The honeycomb hole structure 24 can increase the breathability and softness of the inner liner 16, improving the comfort of the patient.
