Stroke functional electrical stimulation rehabilitation auxiliary device

Abstract

This invention discloses a functional electrical stimulation rehabilitation aid for stroke, belonging to the field of medical rehabilitation aid technology. It includes an electrical stimulation component, a walking component, a height adjustment component, a body support adjustment component, and a rehabilitation component. This device integrates the electrical stimulation component, the body support adjustment component, and the lower limb rehabilitation training component into one unit, overcoming the limitations of traditional devices that separate head electrical stimulation from limb training. It transmits precise electrical signals to the head's nerve function areas through flexible electrode pads within the helmet, directly promoting the repair and regeneration of damaged nerves. Furthermore, the servo motor-driven linkage mechanism in the rehabilitation component simulates human gait, achieving passive training of lower limb joints and muscles. This eliminates the need for patients to transfer between multiple devices, reducing physical exertion and avoiding safety risks during transfers, making it particularly suitable for acute-phase patients with weak limb mobility.

Description

Technical Field

[0001] This invention relates to the field of medical rehabilitation assistive devices, specifically to a functional electrical stimulation rehabilitation assistive device for stroke. Background Technology

[0002] Stroke, a neurological disease with a high incidence and disability rate worldwide, often results in neurological dysfunction after onset, leading to a series of sequelae such as limb movement disorders and cognitive decline. This severely impacts patients' quality of life and places a heavy medical burden and nursing pressure on families and society. Clinical data shows that over 70% of stroke survivors experience varying degrees of lower limb motor dysfunction, and damage to the brain's nerve function is one of the core contributing factors to limb dysfunction. Therefore, in rehabilitation treatment, simultaneously achieving synergistic intervention of brain nerve repair and limb function training has become a key direction for improving rehabilitation outcomes.

[0003] Currently, rehabilitation treatment for stroke patients has formed a diversified system, among which functional electrical stimulation (fEP) and limb rehabilitation training are the two most widely used core technologies. FEP stimulates damaged nerve areas with electrical signals of specific parameters, which can effectively activate dormant nerve cells, promote nerve axon regeneration, and thus improve nerve conduction function, demonstrating clear clinical value in the repair of head nerve injuries. Existing electrical stimulation devices are mostly head-specific stimulators, whose core structure usually includes electrode pads and a stimulation controller. Electrical signals are transmitted through contact between the electrode pads and the scalp. However, these devices are mostly used independently, only able to perform a single nerve stimulation function, and cannot be linked with limb training.

[0004] In limb rehabilitation training, current mainstream assistive devices are mainly divided into two categories: passive training and active training. Passive training devices are more widely used for patients with severe movement disorders. These devices mostly drive limb movement through mechanical structures, simulating the normal movement trajectory of the human body to maintain joint range of motion, prevent muscle atrophy, and lay the foundation for subsequent active training. However, existing limb training devices have significant limitations: their functions are relatively simple, only enabling mechanical movement training of the lower or upper limbs, failing to address the core needs of nerve repair. This results in a lack of support for limb function recovery through neurological improvement, leading to low rehabilitation efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a functional electrical stimulation rehabilitation aid for stroke, so as to solve the problem that traditional rehabilitation devices in the prior art cannot simultaneously achieve head electrical stimulation and limb training.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a functional electrical stimulation rehabilitation assistive device for stroke, comprising an electrical stimulation component, a walking component, a height adjustment component, a body support adjustment component, and a rehabilitation component;

[0007] The electrical stimulation assembly includes a helmet, the inner wall of which is provided with multiple electrode pads;

[0008] The walking assembly includes a base and omnidirectional wheels disposed at the bottom of the base;

[0009] The height adjustment component includes a support column, a movable seat is fitted on the support column, and a plurality of limiting holes are symmetrically opened on the support column. The movable seat is fixed to the support column by a pin.

[0010] The body support adjustment assembly includes a fixed seat fixed to the front side of the movable seat, a slide groove opened on the fixed seat, a reciprocating screw horizontally arranged in the slide groove, an adjustment valve for driving the reciprocating screw to rotate, two adjustment seats threaded to the reciprocating screw and symmetrically arranged along its axial direction, and a support rod fixedly connected to the two adjustment seats respectively.

[0011] The rehabilitation component includes two side fixing frames, each with a drive component 1 installed on it. Each drive component 1 is movably mounted with a connecting rod 1. Each connecting rod 1 is connected to a drive component 2 at its end. Each drive component 2 is movably mounted with a connecting rod 2. Each connecting rod 2 is movably fitted with a telescopic rod at its bottom end. Each connecting rod 2 has an adjustment knob at its bottom, and a base plate is installed at the bottom end of each telescopic rod.

[0012] Furthermore, the support column is vertically fixedly installed on the base, a display is fixedly connected to the rear side of the movable seat, and push handles are symmetrically installed on both sides of the movable seat.

[0013] Furthermore, an elastic support cloth is installed between the two support rods, and a support seat is installed on each of the two support rods. A sponge pad is provided on the side of the elastic support cloth facing the human body, and a strap for fixing the torso is provided on the outside of the sponge pad.

[0014] Furthermore, the fixing frames on both sides are welded to the bottom of the support rods on both sides, and the elastic support cloth is arranged on the rear side of the fixing frames on both sides.

[0015] Furthermore, the outer wall of the helmet is provided with a wire groove, and the electrode pad is fixed to the inner wall of the helmet with medical-grade adhesive, and its surface is covered with a conductive gel layer.

[0016] Furthermore, straps for securing the thighs are installed on the connecting rods on both sides, and straps for securing the feet are symmetrically installed on the base plates on both sides.

[0017] Furthermore, the fixed seat is horizontally mounted on the movable seat, and the support rods on both sides are perpendicular to the fixed seat.

[0018] Furthermore, the adjustment knob fixes the telescopic rod to the bottom of the connecting rod two, and the base plate is movably installed at the bottom of the telescopic rod.

[0019] Compared with existing technologies, the beneficial effects of the functional electrical stimulation rehabilitation aid for stroke provided by this invention are as follows:

[0020] 1. By integrating the electrical stimulation component, body support adjustment component, and lower limb rehabilitation training component into one unit, the limitations of traditional devices that separate head electrical stimulation and limb training are overcome. The electrical stimulation component transmits precise electrical signals to the head's nerve function areas through flexible electrode pads inside the helmet, directly promoting the repair and regeneration of damaged nerves. At the same time, the rehabilitation component uses a servo motor to drive a linkage mechanism to simulate human gait, achieving passive training of lower limb joints and muscles. The two form a synergistic rehabilitation link of nerve awakening and motor remodeling, significantly improving the overall rehabilitation efficiency of stroke patients. Compared with single-function devices, patients do not need to transfer between multiple devices, which reduces physical exertion and avoids safety risks during the transfer process, making it especially suitable for acute patients with weak limb mobility.

[0021] 2. A full-dimensional adaptation system is constructed through the height adjustment component and the body support adjustment component, which can meet the personalized needs of different patients. The support column and movable seat can be adjusted to achieve fine adjustment within the height range of 150cm-190cm, and the adjustment process does not require additional tools. Loosening the pin can complete the positioning and fixation. The body support adjustment component uses a handwheel-driven reciprocating screw structure to drive the titanium alloy support rods on both sides to move synchronously relative to each other or in opposite directions, quickly adapting to the torso width of different patients.

[0033] As attached Figure 1 To be continued Figure 7 As shown:

[0034] Example 1:

[0035] The present invention provides a functional electrical stimulation rehabilitation assistive device for stroke, comprising an electrical stimulation component 1, a walking component 2, a height adjustment component 3, a body support adjustment component 4, and a rehabilitation component 11;

[0036] The electrical stimulation component 1 includes a helmet 101. Multiple electrode pads 102 are disposed on the inner wall of the helmet 101, and a wire groove is provided on the outer wall of the helmet 101. The electrode pads 102 are fixed to the inner wall of the helmet 101 with medical-grade adhesive, and their surfaces are covered with a conductive gel layer. The helmet 101 is made of ABS medical-grade plastic, and its inner wall conforms to the contour of the human head. Six to eight evenly distributed flexible electrode pads 102 are fixed thereon with medical-grade double-sided adhesive. A wire groove for storing wires is integrally formed on the outer wall of the helmet 101. The electrode pads 102 are electrically connected to the device's built-in electrical stimulation controller through wires in the wire groove. The surface of the electrode pads 102 is covered with a replaceable conductive gel layer to improve conductivity and wearing comfort. Elastic chin straps are also provided on both sides of the helmet 101 to ensure a stable fit.

[0037] The walking component 2 includes a base 21 and a caster wheel 22 disposed at the bottom of the base 21. The base 21 is a rectangular base made of stainless steel, and the caster wheel 22 is a silent type with brake pads and is fixedly connected to the base 21 by a pin 34.

[0038] Working principle: When in use, the patient puts on the helmet 101 and fixes it with the chin strap. Then, the patient aligns the electrode pads 102 with the functional areas of the head that require electrical stimulation and activates the electrical stimulation controller. The electrode pads 102 transmit a gentle electrical stimulation signal to the head through the conductive gel layer to promote the recovery of the nerve function of the head in stroke patients. At the same time, in conjunction with the walking component 2 and the rehabilitation component 11, the brake pads of the universal wheel 22 are released, allowing the patient to move flexibly through the universal wheel 22. After reaching the target position, the brake pad fixing device is locked to ensure stability during use.

[0039] Example 2:

[0040] This embodiment is basically the same as the previous embodiment, except that the height adjustment component 3 includes a support column 31 (the support column 31 is made of high-strength 6061 aluminum alloy and adopts a hollow rectangular structure design, which effectively reduces the overall weight and ensures sufficient load-bearing capacity through the 8mm wall thickness structure design, which can stably support the total weight of the patient's body and related components with a maximum load capacity of 150kg). A movable seat 32 is fitted on the support column 31 (the movable seat 32 is an annular structure with an internal guide sleeve. The guide sleeve is made of polytetrafluoroethylene, and its inner sidewall is tightly fitted with the outer sidewall of the support column 31, which not only ensures the smooth sliding of the movable seat 32 along the axial direction of the support column 31, but also effectively reduces wear during the sliding process). Multiple limiting holes 33 are symmetrically opened on the support column 31. The movable seat 32 is fixed to the support column 31 by a pin 34. (The limiting holes 33 symmetrically opened on the support column 31 are through holes with a diameter of 13mm, which are evenly distributed along the length of the support column 31. The spacing between adjacent limiting holes 33 is set to 5cm. This spacing design can realize the fine adjustment of the height of the device to meet the usage needs of patients with a height range of 150cm-190cm. When the height needs to be adjusted, simply pull out the pin 34, push the movable seat 32 to the appropriate position, and then pass the pin 34 through the threaded hole of the movable seat 32 and screw it into the corresponding limiting hole 33 to complete the fixation of the movable seat 32. The entire adjustment process does not require any additional tools and is convenient and efficient to operate.)

[0041] The body support adjustment assembly 4 includes a fixed base 41 fixed to the front of the movable base 32 (the fixed base 41 is made of integral die-cast engineering plastic material, with an overall rectangular structure, and its back is tightly connected to the mounting plane on the front of the movable base 32 by 4 M8 bolts, the bolts are distributed in a rectangular array to ensure that the flatness error of the fixed base 41 after installation does not exceed 0.5mm) and a slide groove 43 opened on the fixed base 41 (the slide groove 43 is a T-shaped structure, with a groove width of 20mm and a groove depth of 15mm). 3. Both inner side walls are provided with polished guide surfaces to reduce frictional resistance when the adjusting seat 45 slides. A reciprocating lead screw 44 is horizontally set in the slide groove 43. (The reciprocating lead screw 44 is made of 45# steel and has undergone heat treatment. Both ends of the lead screw are rotatably connected to the side wall of the fixed seat 41 via deep groove ball bearings. The outer ring of the bearing is interference-fitted with the mounting hole of the fixed seat 41 to ensure coaxiality during lead screw rotation. Both ends of the reciprocating lead screw 44 are machined with trapezoidal threads of opposite directions, with a thread lead of 10mm. This structural design...) This configuration includes: two adjusting seats 45 threaded to the lead screw 44, which can move synchronously relative to each other or in opposite directions along the slide groove 43 when the lead screw rotates, thereby achieving symmetrical adjustment of the spacing between the support rods 46; an adjusting valve 42 that drives the reciprocating lead screw 44 to rotate (the adjusting valve 42 that drives the reciprocating lead screw 44 to rotate adopts a transmission structure of handwheel plus bevel gear set, with anti-slip texture on the surface to facilitate the force operation of medical staff, the central shaft of the handwheel extends into the interior of the fixed seat 41, and achieves vertical transmission with one end of the reciprocating lead screw 44 through the bevel gear set, the bevel gear adopts a hard tooth surface design, the transmission efficiency is as high as 95% or more, and it can effectively avoid the jamming phenomenon in the transmission process); two adjusting seats 45 threaded to the reciprocating lead screw 44 and symmetrically arranged along its axis; and support rods 46 fixedly connected to the two adjusting seats 45 respectively (the support rods 46 are made of titanium alloy, which has excellent strength and can effectively reduce the weight of the components, and the axis of the support rods 46 is set at 90° perpendicular to the upper surface of the fixed seat 41 to ensure that the force direction during support is reasonable).

[0042] The support column 31 is vertically fixed on the base 21. The display 5 is fixedly connected to the rear of the movable seat 32, and push handles 6 are symmetrically installed on both sides of the movable seat 32. (The display 5 is electrically connected to the main control module of the device and can display parameters such as electrical stimulation intensity, rehabilitation training duration, and component operation status in real time. It also supports touch operation for easy parameter setting and function switching. The push handles 6 symmetrically installed on both sides of the movable seat 32 are U-shaped and made of bent aluminum alloy tubing. The surface is covered with 30mm thick foam sponge, which is comfortable to hold. The height of the push handles 6 is flush with the center of the movable seat 32, which conforms to the ergonomic design and does not require medical staff to bend over to push the device.)

[0043] The fixed base 41 is horizontally mounted on the movable base 32, and the support rods 46 on both sides are perpendicular to the fixed base 41.

[0044] An elastic support cloth 7 is installed between the two support rods 46, and a support seat 8 is installed on each of the two support rods 46 (the support seat 8 is made of medical-grade silicone material, with an internal metal skeleton to enhance the support strength, and the silicone surface has anti-slip texture. The support seat 8 is adapted to the height of the patient's arm contour, making it convenient to assist the patient in using their arm to support their body). A sponge pad 9 is provided on the side of the elastic support cloth 7 facing the human body, and a strap 10 for fixing the torso is provided on the outside of the sponge pad 9.

[0045] Working principle: Before use, adjust the height of the movable seat 32 according to the patient's height using the height adjustment component 3, and screw the fastening pin 34 into the corresponding height limiting hole 33 to complete the fixation; then rotate the adjustment valve 42, which drives the reciprocating screw 44 to rotate. Since the threads at both ends of the reciprocating screw 44 rotate in opposite directions, the two adjustment seats 45 will move relative to or away from each other along the slide groove 43, thereby adjusting the distance between the two side support rods 46 so that the elastic support cloth 7 matches the width of the patient's torso. Then place the patient on the device, with the patient's back leaning against the sponge pad 9 of the elastic support cloth 7, and fix the torso with the strap 10 to prevent the body from shaking during rehabilitation; then, after starting the electrical stimulation component 1, the electrode pad 102 will provide electrical stimulation to the head. At the same time, medical staff can observe the electrical stimulation parameters and the patient's feedback in real time through the display 5, and adjust the parameters as needed to improve the safety and targeted nature of rehabilitation.

[0046] Example 3:

[0047] This embodiment is basically the same as the previous embodiment, except that the rehabilitation component 11 includes two side fixing frames 111, and each side fixing frame 111 is equipped with a drive component 112 (the drive component 112 is a DC servo motor with a rated power of 200W. This motor has the characteristics of adjustable speed and stable torque, and the motor shell adopts an IP67 waterproof and dustproof design, which can adapt to the influence of environmental factors such as sweat and water stains that may occur in the rehabilitation scene; the output shaft of the drive component 112 is rigidly connected to one end of the connecting rod 113 through an elastic coupling. The elastic coupling is equipped with a rubber buffer pad, which can effectively absorb the impact load when the motor starts and stops, and avoid the deformation of the connecting rod mechanism due to excessive instantaneous force). Each side drive component 112 is movably equipped with a connecting rod 113 ( Drive component 114 is movably mounted on the ends of connecting rod 113 on both sides via spherical bearings. The selection of spherical bearings allows for multi-angle rotation of ±30° between connecting rod 113 and drive component 114, thereby better simulating the movement trajectory between the human thigh and calf. The model of drive component 114 is the same as that of drive component 112, ensuring the coordination of lower limb flexion and extension movements. Its output shaft is also fixedly connected to one end of connecting rod 115 via a flexible coupling. Drive component 114 is mounted on the ends of connecting rod 113 on both sides. Connecting rod 115 is movably mounted on the two drive components 114 on both sides. Telescopic rods 116 are movably sleeved at the bottom of connecting rods 115 on both sides. Adjustment knobs 117 are installed at the bottom of connecting rods 115 on both sides. Base plates 119 are installed at the bottom of telescopic rods 116 on both sides.

[0048] The two side fixing frames 111 are welded to the bottom of the two side support rods 46 respectively, and the elastic support cloth 7 is set on the rear side of the two side fixing frames 111;

[0049] Straps 118 for fixing the thighs are installed on the two connecting rods 115 on both sides, and straps 110 for fixing the feet are symmetrically installed on the two base plates 119 on both sides (the straps are made of nylon webbing with Velcro fasteners on the surface. The length of the straps can be adjusted from 60cm to 100cm. By wrapping around the patient's torso and fastening them, the patient's body can be stably restricted to the structure, avoiding the impact of body swaying on the training effect or the creation of safety hazards during rehabilitation training).

[0050] Adjusting knob 117 fixes telescopic rod 116 to the bottom of connecting rod 2 115, and base plate 119 is movably installed at the bottom of telescopic rod 116;

[0051] Working principle: Before use, adjust the length of the extension rod 116 extending from the connecting rod 115 according to the length of the patient's lower limb. After determining the appropriate length by referring to the scale line on the extension rod 116, tighten the adjustment knob 117 to complete the fixation. After the patient puts on the helmet 101 and fixes the torso with the first strap 10, put the thigh into the second strap 118 and the foot into the base plate 119. The lower limb is fixed by the second strap 118 and the third strap 110 respectively, ensuring that the lower limb is stably connected to the rehabilitation component 11.

[0052] After the device is activated, the electrode 102 of the electrical stimulation component 1 transmits electrical stimulation signals to the head. At the same time, the first drive component 112 and the second drive component 114 operate in coordination according to a preset program: the first drive component 112 drives the first connecting rod 113 to rotate around its output shaft to realize the flexion and extension of the thigh; the second drive component 114 drives the second connecting rod 115 to rotate around its output shaft, and with the length of the telescopic rod 116 fixed, realizes the flexion and extension of the lower leg.

[0053] Through the synergistic effect of the two, the movement trajectory of the lower limbs during normal walking is simulated, and passive training of the lower limb joints and muscles of stroke patients is carried out to promote the recovery of lower limb motor function. During the training process, medical staff can monitor the electrical stimulation parameters and the movement status of the rehabilitation component 11 in real time through the display 5, and adjust the movement speed and electrical stimulation intensity according to the patient's tolerance to ensure the safety and effectiveness of rehabilitation training.

[0054] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
