Those skilled in the art can understand the advantages and effects of this utility model from the content disclosed in this specification. This utility model can be implemented or applied through other different specific embodiments, and various details in this specification can also be modified and changed based on different viewpoints and applications without departing from the spirit of this utility model. Furthermore, the accompanying drawings of this utility model are for simple illustrative purposes only and are not depictions of actual dimensions, as stated in advance. The following embodiments will further describe the relevant technical content of this utility model in detail, but the disclosed content is not intended to limit the scope of protection of this utility model.

[0042] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 ,as well as Figure 8 As shown, this embodiment provides a modular support device for foot drop correction. The modular support device includes an ankle joint fixation module, a foot elastic support module, and a dorsiflexion assist module. The foot elastic support module is disposed on the user's sole area. The ankle joint fixation module surrounds the patient's ankle joint area and covers the front and sides of the ankle joint. The dorsiflexion assist module is disposed on the rear side of the ankle joint fixation module and extends to the posterior side of the lower leg. The foot elastic support module and the dorsiflexion assist module are disposed on both sides of the ankle joint fixation module and are detachably connected to the ankle joint fixation module.

[0043] The dorsiflexion assist module includes an elastic band 8, an elastic assist component, and a fixing component. The fixing component is fixed to the back of the lower leg to form a support platform. The assist component is disposed in the fixing component. One end of the elastic band 8 is detachably connected to the foot elastic support module. The other end of the elastic band 8 is drivenly connected to the elastic assist component and linearly adjusts the traction amount of the foot elastic support module.

[0044] The fixing component includes a support base 9 and a support groove opened along the support base 9. The width of the support groove is selected according to the circumference of the leg used, that is, the support base 9 that is suitable is selected.

[0045] Optionally, the ankle joint fixation module includes a fixation seat 2, a fixation component, and a limiting component. The fixation seat 2 forms a placement groove 18 along its own concave shape. The fixation seat 2 is nested in the user's ankle area. The fixation component is disposed on both sides of the placement groove 18, and the limiting component is disposed on the inner wall of the placement groove 18.

[0046] The fixed base 2 has a connecting cavity 3 on the side away from the limiting member, which is provided for the elastic band 8. A connecting rod 17 is provided in the connecting cavity 3, and one end of the elastic rod is connected to the connecting rod 17.

[0047] Optionally, the foot elastic support module includes a foot placement plate 1, a connecting member, and a correction member. The correction member is disposed on the upper surface of the foot placement plate 1 and contacts the user's foot area. The connecting member is disposed on the side of the foot placement plate 1 away from the user's toe area and is detachably connected to the fixing base 2.

[0048] Optionally, the foot placement plate 1 has at least two hidden cavities 7 on the contact surface with the user's foot area, and the correction component is respectively hidden in the at least two hidden cavities 7.

[0049] The foot placement plate 1 is built into the placement groove 18 of the placement seat.

[0050] During the correction process, the correction component in the hidden cavity 7 is inflated to support the user's foot, thereby changing the sagging of the user's foot area and the change in foot posture.

[0051] The foot region includes the arch and the forefoot.

[0052] The foot placement plate 1 is made of a composite flexible polymer and has a breathable design to improve comfort during long-term wear.

[0053] In addition, the correction component includes a correction airbag 5, an inflation pump 6, an electronic deflation valve, and an air supply pipe. One end of the air supply pipe is connected to the correction airbag 5 and communicates internally with it. The other end of the air supply pipe is connected to the inflation pump 6 to form a correction part. The correction part is disposed on the upper surface of the foot placement plate 1.

[0054] Optionally, the correction component also includes a control panel 23, which is electrically connected to the air pump 6 and the electronic deflation valve.

[0055] The control panel 23 is provided with an inflation button 19 and a deflation button 22, and the control panel 23 is located on the outer periphery of the fixed base 2.

[0056] At the same time, the user operates the inflation button 19 in the control panel 23 to inflate the corrective airbag 5, thereby changing the state of the corrective airbag 5 and providing support and assistance to the sole of the foot, and changing the user's foot posture, thereby correcting the user's foot drop.

[0057] In this embodiment, in addition to correcting the user's foot by means of the correcting member, the ankle area in use is also limited by means of the limiting member, thereby restricting the muscle groups in the user's ankle area and thus training the muscle groups synchronously.

[0058] Optionally, the limiting component includes a limiting airbag 4, an electric pump, and an electronic pressure relief valve. The electric pump is connected to and internally communicates with the limiting airbag 4 to form a limiting part. The limiting part is disposed on the inner wall of the placement groove 18, and the electronic pressure relief valve is disposed in the limiting airbag 4.

[0059] The limiting component also includes a control panel 14, which is provided with a pressure release button 15 and a limiting button 16. The pressure button is electrically connected to the electronic pressure valve. When the pressure button is triggered, the electronic pressure valve will release the gas in the limiting airbag 4 to the outside, thereby releasing the limitation of the limiting airbag 4.

[0060] In addition, the limit button 16 is electrically connected to the electric pump. After the limit button 16 is triggered, the electric pump inflates the limit airbag 4, thereby causing the limit airbag 4 to expand and limit the muscle groups in the user's ankle area. This serves to assist and cooperate with the correction component to perform auxiliary correction training on the user's exposed area.

[0061] The control panel 14 is mounted on the outer wall of the support base 9, such as Figure 3 As shown.

[0062] Meanwhile, the limit button 16 and the pressure relief button 15 establish a communication connection with the electric pump and the electronic pressure relief valve through wireless transmission communication, thereby realizing the control of the electric pump and the electronic pressure relief valve.

[0063] By combining the ankle joint fixation module and the foot elastic support module, the foot receives stable support while limiting abnormal ankle movements. This provides advantages such as improved gait stability, prevention of secondary injuries, and enhanced plantar support.

[0064] The connecting member includes a connecting seat 20 and a connecting block. The connecting seat 20 is disposed on the side of the fixed seat 2 away from the foot placement plate 1 and located on the outer wall surface of the fixed seat 2. The connecting seat 20 is disposed on the outer periphery of the fixed member (as shown in the figure, the connecting seat 20 is disposed on the outer wall surface of the support seat 9).

[0065] The connecting seat 20 and the connecting block are used in pairs and are detachably connected.

[0066] When it is necessary to assemble the dorsiflexion assist module and the ankle joint fixation module together using fixation components, the connecting block is assembled onto the connecting seat 20 so that the two can be combined to form a shape such as Figure 8 As shown.

[0067] Optionally, the elastic assist component includes an adjustment seat 10, an adjustment cavity 21, an adjustment rod 11, and an adjustment knob 24. The adjustment seat 10 is disposed on the outer wall of the support seat 9, and the adjustment seat 10 has an adjustment cavity 21. One end of the adjustment rod 11 is hinged to the inner wall of the adjustment cavity 21, and the other end of the adjustment rod 11 passes through the side wall of the adjustment cavity 21 and extends to the outer wall of the fixed seat 2 to form a connecting part. The adjustment knob 24 is disposed on the connecting part. The rod body of the adjustment rod 11 has a locking hole at one end near the connecting part. The support seat 9 has a limiting protrusion 13, and the limiting protrusion 13 has an insertion hole. The insertion hole and the locking hole are disposed opposite to each other.

[0068] The elastic band 8 passes through the cavity of the adjustment cavity 21 and is connected to the rod of the adjustment rod 11.

[0069] In this embodiment, the end of the adjusting rod 11 with the locking hole is set as the adjusting end, and it is equipped with a screw. When the user or medical staff rotates the adjusting rod 11, the threaded hole at the hinge position between the adjusting rod 11 and the inner wall of the adjusting cavity 21 rotates, thereby winding the elastic band 8 around the adjusting rod 11 and assisting in the traction of the foot elastic support module, thus providing auxiliary traction assistance to the foot elastic support module.

[0070] In this embodiment, the adjustment rod 11 can be manually adjusted according to actual needs, thereby adjusting the elasticity of the elastic band 8, so as to provide auxiliary traction and assistance to the foot elastic support module.

[0071] Optionally, the elastic assist component further includes a locking rod 12, which is inserted into the insertion hole and restricts the rotation of the adjusting rod 11.

[0072] By combining the foot elastic support module and the dorsiflexion assist module, the sole of the foot can receive appropriate traction assistance to help complete the dorsiflexion movement, which has the advantages of improving foot drop gait, reducing toe dragging, and improving walking smoothness.

[0073] By working together with the dorsiflexion assist module and the ankle joint fixation module, the dorsiflexion assist torque can be effectively transmitted to the foot, while limiting abnormal ankle rotation. This has the advantages of improving the correction effect, enhancing assist stability, and avoiding ankle discomfort during the correction process.

[0074] The modular support device also includes a central processing unit, which is connected to the ankle joint fixation module, the foot elastic support module, and the dorsiflexion assist module. The central processing unit provides centralized control over the ankle joint fixation module, the foot elastic support module, and the dorsiflexion assist module, thereby improving the overall reliability and stability of the device.

[0075] The control of the central processing unit, ankle joint fixation module, foot elastic support module, and dorsiflexion assist module is a technical means well known to those skilled in the art, and therefore will not be described in detail in this embodiment.

[0076] By having the ankle joint fixation module, foot elastic support module, and dorsiflexion assist module work together as a whole, a complete biomechanical support system is formed for the foot, ankle, and lower leg. This system has the advantages of enhancing correction accuracy, providing personalized adjustment, improving wearing comfort, and adapting to the needs of different rehabilitation stages.

[0077] The above-disclosed content is only a preferred and feasible embodiment of the present utility model, and is not intended to limit the protection scope of the present utility model. Therefore, all equivalent technical changes made based on the contents of the present utility model specification and drawings are included within the protection scope of the present utility model.
