Description

Technical Field

[0001] The present invention relates to the technical field of foot drop correction, and in particular to an intelligent multi-directional dynamic anti-foot drop correction device based on pneumatic control. Background Art

[0002] In the field of rehabilitation medicine and neurorehabilitation, foot drop is a common and complex lower limb dysfunction, mainly caused by nerve damage, musculoskeletal system damage or long-term bed rest. Its typical manifestation is the loss of dorsiflexion function of the ankle joint, which causes the patient's toes to drop when walking or moving, which not only affects the stability of gait, but also seriously reduces the quality of life. Foot drop symptoms are common in patients with stroke, spinal cord injury, peripheral neuropathy, etc.

[0003] Especially in comatose or bedridden patients, early use of foot drop correction devices is particularly important. These patients usually lack active movement ability and are prone to complications such as foot drop and foot pressure sores. Therefore, the correction devices suitable for such patients need to have specific functional characteristics to provide effective support and protection to achieve therapeutic rehabilitation effects.

[0004] However, traditional foot drop correctors still have limitations in terms of dynamic support, precise control of support force, and protection of foot comfort. Many devices rely on mechanical support structures, lack flexibility, and cannot adapt to the multi-directional movement needs that patients may have during rehabilitation. In addition, the support strength of traditional devices often cannot be adjusted in real time according to the actual condition of the patient, which may cause discomfort or injury. Especially for bedridden patients, this limitation may affect their early rehabilitation effects.

[0005] Therefore, there is an urgent need for an innovative foot drop correction device with multi-directional dynamic support and intelligent feedback control functions, which can flexibly adapt to the patient's foot condition, reduce the risk of foot drop, and provide effective support for early rehabilitation. This design not only helps to improve the patient's rehabilitation experience, but also promotes their functional recovery, achieves the effect of rehabilitation treatment, and improves the quality of life. Summary of the invention

[0006] The purpose of the present invention is to solve the above-mentioned problems of the prior art and provide an intelligent multi-directional dynamic anti-foot drop correction device based on pneumatic control. Through multi-directional dynamic support adjustment and intelligent feedback control, it breaks through the limitations of the prior art in terms of fixed support and adjustment accuracy. Its innovative design not only improves the patient's rehabilitation experience, but also effectively improves the clinical treatment effect, reduces the workload of clinical staff, and enables foot drop patients to obtain more efficient auxiliary function training support in long-term rehabilitation. The specific technical solution is as follows: An intelligent multi-directional dynamic anti-foot droop correction device based on pneumatic control, comprising a box body, which is a three-dimensional trapezoidal structure, a support plate is arranged on the inclined surface of the box body, the support plate is elastically connected to the box body in a telescopic manner, a foot fixing device is arranged above the support plate, and the foot fixing device is detachably connected to the support plate; the box body comprises an airbag, a movable plate, a limit baffle, an inflation host, and a control system; the airbag is placed in a corresponding circular ring, and the airbag pushes the corresponding movable plate by inflation; the movable plate limits the angle of movement by the limit baffle; the inflation host is arranged below the inclined surface of the box body, and the box body is provided with a reserved hole, and the inflation host is connected to each airbag through a pipe passing through the hole; the control system comprises a microcontroller and a pressure sensor, and the microcontroller receives a signal from the pressure sensor to control the inflation of the inflation host or control the solenoid valve to release excess air pressure in the airbag.

[0007] Preferably, the number of the airbags, the rings and the movable plates is 3.

[0008] Preferably, the foot fixing device is a shoe composed of a buckle and a silicone coated fabric strap, the sole and the support plate are detachably connected by a U-shaped lock, and the heel is wrapped in a U-shape with a memory foam material.

[0009] Preferably, the movable plate is made of a lightweight material, and the surface of the movable plate is covered with a buffer pad, wherein the buffer pad is selected from any one of full-line fabric, cotton cloth, and sponge.

[0010] Preferably, the support plate is adjusted 0-45 degrees up and down and 0-45 degrees left and right.

[0011] Compared with the closest prior art, the technical solution provided by the present invention has the following beneficial effects: 1. The present invention combines an air pressure system with a microcontroller to achieve multi-directional dynamic adjustment of foot support through automatic inflation and deflation; the device can flexibly adjust the support strength at multiple angles, such as front, back, left, and right, according to the patient's real-time foot status; this design effectively overcomes the limitations of the fixed bracket of the traditional device, allowing patients to obtain more natural foot mobility during rehabilitation training and more effectively improve the functional exercise and rehabilitation effect of patients; the heel part adopts a U-shaped fully wrapped foam material to effectively buffer and decompress, significantly reducing the risk of local pressure sores in patients; 2. The pressure sensor of the present invention is linked with a microcontroller to realize intelligent feedback control.

DETAILED DESCRIPTION

[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Please refer to Figure 1-2 .

The above settings can dynamically support the foot in multiple directions to meet the needs of different rehabilitation stages. Through the linkage between the pneumatic system and the support plate, the support plate can be flexibly adjusted in multiple directions such as front, back, left, and right, providing all-round support for the foot. Compared with the traditional fixed bracket, this dynamic support design meets the different activity needs of patients in each rehabilitation stage, effectively preventing muscle stiffness and poor blood circulation caused by fixed posture, and solving the problem of foot drop. In addition, based on real-time feedback from pressure sensors and intelligent adjustment by microcontrollers, the support force control system can automatically and accurately adjust the support force to ensure that the support force is always within a safe and effective range, avoiding discomfort or injury caused by insufficient or excessive support force in traditional devices. This feedback adjustment mechanism significantly improves the accuracy of the support force and the safety of patients during rehabilitation.

[0015] Furthermore, the number of the airbags, the rings, and the movable plates are all three.

[0016] Airbag a: placed in the ring a51. When airbag a is inflated, it pushes the movable plate a9, generating a forward thrust to provide forward support for the foot.

[0017] Airbag b: placed in the ring b52. When the airbag b is inflated, it pushes the movable plate b10, generating a thrust to the left, but the maximum limit of the movable plate moving to the left is limited by the limit baffle b62 to prevent excessive displacement.

[0018] Airbag c: placed in the ring c53. When airbag c is inflated, it pushes the movable plate c11, generating a thrust to the right, but the maximum limit of the movable plate moving to the right is limited by the limit baffle c63, preventing the movable plate from exceeding the safety range.

[0019] Furthermore, the foot fixing device is a shoe composed of a buckle 7 and a silicone coated fabric strap 8, and the sole is detachably connected to the support plate 2 by a U-shaped lock, so that the shoe can be replaced according to actual needs and is suitable for a variety of ages and sizes. The silicone coated fabric strap has high flexibility and anti-slip performance, and combined with the buckle, ensures that the device will not slip off during use.

[0020] Furthermore, the heel is wrapped in a U-shape with memory foam material, which can fully protect the heel and ankle, buffer local pressure, reduce the risk of pressure sores, and increase wearing comfort and stability.

[0021] Furthermore, the movable plate 2 is made of a lightweight material, and the surface of the movable plate is covered with a cushion pad, wherein the cushion pad is selected from any one of full-line fabric, cotton cloth, and sponge. The setting of the cushion pad provides comfort protection for the foot and effectively reduces the pressure caused by long-term wear. The strap is made of silicone coated fabric to further improve comfort, avoid skin friction or pressure pain caused by traditional devices, and is suitable for patients to wear for a long time and meets the needs of rehabilitation training.

[0022] Furthermore, through the linkage between the pneumatic system and the support plate, the support plate 2 can be flexibly adjusted in multiple directions such as front, back, left and right, providing all-round support for the foot. The support plate 2 can be adjusted 0-45 degrees up and down, and 0-45 degrees left and right. Compared with the traditional fixed support, this dynamic support design meets the different activity needs of patients at various stages of rehabilitation, effectively prevents muscle stiffness and poor blood circulation caused by fixed posture, and promotes the recovery of foot function.
