Description

Technical Field

[0002] Lower limb rehabilitation aims to improve patients' lower limb function through a series of rehabilitation measures and treatments, helping them regain the ability to walk and carry out daily activities to the greatest possible degree. Currently, key lower limb rehabilitation methods include physical therapy, exercise training, functional electrical stimulation, and the use of assistive devices. Effective rehabilitation methods can significantly help patients further restore their mobility, significantly improving rehabilitation outcomes and reducing social pressure.

[0003] Most of the rehabilitation equipment in some related technologies use physical rehabilitation methods, which are single. The evaluation of rehabilitation effects relies on the patient's intuitive response and actual observation. The rehabilitation stimulation parameters of this method are single, and it is not possible to conduct in-depth research on EEG components to evaluate rehabilitation effects. Another part of the rehabilitation equipment in related technologies, such as CN204016656U-a multi-position electric wheelchair with rehabilitation training function, builds a lower limb rehabilitation system based on brain-computer interface technology, and combines visual and auditory stimulation for multimodal lower limb rehabilitation. Although this rehabilitation method can obtain patient information in real time and adjust rehabilitation methods and parameters. However, when this solution is implemented, because the patient continues to perform rehabilitation exercises, he or she may be easily distracted by the soreness caused by sitting still or sitting for a long time, or cannot concentrate on visual and auditory stimulation due to external factors such as sweating, resulting in a poor user experience and affecting the patient's rehabilitation effect.

[0039] Reference Figures 1 to 8 The lower limb rehabilitation equipment of the first embodiment of the present application includes a wheelchair frame 100, a rehabilitation module 200 and a comfort module 300.

[0040] The wheelchair frame 100 includes a seat 110 and a backrest 120; the rehabilitation module 200 is arranged on the wheelchair frame 100, and the rehabilitation module 200 includes a lifting stimulation mechanism 210 and an audio-visual display mechanism 220 arranged to cooperate with the lifting stimulation mechanism 210. The lifting stimulation mechanism 210 includes a rehabilitation air flow component 211, an electrical stimulation control component 212 and a lifting component 213. The lifting component 213 is used to lift the legs for rehabilitation, and the electrical stimulation control component 212 is arranged close to the lifting component 213 and is used for electrical stimulation. Rehabilitation, the rehabilitation air flow component 211 is arranged adjacent to the lifting component 213 and is used to diffuse the air flow output by the air circulation mechanism 320; and the comfort module 300 includes a double-layer cushion structure 310 and an air circulation mechanism 320, the double-layer cushion structure 310 is respectively arranged on the seat 110 and the backrest 120, and a plurality of ventilation holes are arranged on the surface of the double-layer cushion structure 310, and the air circulation mechanism 320 is used to output temperature-controlled air flow to the rehabilitation air flow component 211 and the double-layer cushion structure 310 respectively.

[0041] It can be understood that lower limb stimulation rehabilitation training is achieved through a multi-modal combination of different parameters of collective sensory stimulation, electrical stimulation and audio-visual stimulation. At the same time, in order to further improve and enhance the comfort of the system rehabilitation, the seat cushion and back are designed as a double-layer ventilation structure, and an air circulation mechanism 320 is configured to ventilate and dissipate heat for the seat cushion, back and lifting stimulation mechanism 210. The air flow with controllable temperature is used to relieve the discomfort caused by sitting still or sitting for a long time during the rehabilitation process, and to ensure a certain comfort of the legs, thereby improving the continuous comfort during the system rehabilitation process, better strengthening the nerve conduction between the legs and the body, and further improving the rehabilitation effect.

[0042] In some embodiments, the lower limb rehabilitation device of the first aspect of the present application can be used in conjunction with a lower limb rehabilitation robot data acquisition and analysis system. This system is used to collect rehabilitation physiological data from patients with lower limb motor dysfunction and then uses big data analysis and processing technology to provide more personalized, comprehensive, and precise rehabilitation treatment and rehabilitation status visualization services for patients with lower limb motor dysfunction.

At the same time, it combines different frequencies of electrical stimulation (FES) to stimulate the lower limbs in a multimodal overlapping manner. At the same time, it designs a leg-lifting animation for visual and auditory stimulation. The multimodal stimulation rehabilitation of the lower limbs is carried out with different parameters of collective sensory stimulation, electrical stimulation, and visual and auditory stimulation. While designing multiple aspects of stimulation, the system further improves and enhances the comfort of system rehabilitation. The seat cushion and back are improved and designed with a double-layer mesh cover, and a temperature air circulator is added between the seat cushion mesh cover and the back mesh cover. It can transmit a controllable temperature air flow between the double-layer mesh and the backrest 120, alleviating the discomfort caused by sitting still or sitting for a long time during the rehabilitation process, and ensuring continuous comfort during the system rehabilitation process. Finally, an air circulation plate is installed on the rehabilitation device of the somatosensory stimulation part to ensure a certain comfort of the legs. The air circulation panel and double-layer mesh design can better enhance nerve conduction between the legs and the body, maintaining comfort during the rehabilitation process while alleviating the discomfort caused by sitting still or sitting for a long time. It can also enable the rehabilitator to focus on visual and auditory stimulation, further improving the rehabilitation effect.

[0045] In some embodiments of the present application, the double-layer cushion structure 310 includes a cushion component 311, which is arranged on the seat body 110. The cushion component 311 includes a cushion body 3111, a cushion air circulation plate 3112 and a cushion grid layer 3113. The cushion grid layer 3113 is respectively arranged on the upper and lower surfaces of the cushion body 3111, and a cushion cavity for air flow is formed between the upper and lower surfaces of the cushion body 3111. The cushion air circulation plate 3112 is arranged on one side of the cushion body 3111, and a cushion air supply port 3114 is provided on the cushion air circulation plate 3112. The cushion air supply port 3114 is used to respectively connect the cushion cavity and the air circulation mechanism 320. It can be understood that the cushion mesh layers 3113 are respectively arranged on the upper and lower surfaces of the cushion body to facilitate heat dissipation and air flow. The cushion body 3111 has a certain supporting function so as to form a double-layer ventilation structure between the cushion mesh layers 3113 on the upper and lower surfaces. The cushion air circulation plate 3112 is used to receive the air flow from the air circulation mechanism 320 and enable the air flow to flow fully in the cushion cavity and flow away from the cushion mesh layers 3113 on the upper and lower surfaces, thereby improving comfort.

[0046] In some embodiments, parameters such as the temperature and flow rate of the air flow output by the air circulation mechanism 320 to the cushion component 311 can be adaptively adjusted according to patient requirements or data such as body temperature, thereby further improving comfort.

[0047] In some embodiments of the present application, a double-layer cushion structure 310 includes a cushion body 312, a double-layer elastic mesh layer 313, and a back air circulation plate 314. The cushion body 312 and the double-layer elastic mesh layer 313 are disposed on the backrest 120 with an interval therebetween. A back cavity for air circulation is formed between the double-layer elastic mesh layers 313. The back air circulation plate 314 is disposed on one side of the double-layer elastic mesh layer 313 and is provided with a back air delivery port 3141, which connects the back cavity to the air circulation mechanism 320. It is understood that the cushion body 312 is configured to provide comfortable and soft support, the double-layer elastic mesh layer 313 is configured to form a double-layer ventilation structure, and the back air circulation plate 314 is configured to receive air flow from the air circulation mechanism 320 and allow the air flow to flow fully within the back cavity and out from the upper and lower surfaces of the double-layer elastic mesh layer 313, thereby improving comfort.

[0048] In some embodiments, the temperature, flow rate and other parameters of the air flow output by the air circulation mechanism 320 to the back air circulation plate 314 can be adaptively adjusted according to patient requirements or data such as body temperature, thereby further improving comfort.

[0049] In some embodiments of the present application, the air circulation mechanism 320 includes an air circulation unit body 321, a first air supply pipe 322, a second air supply pipe 323, and a third air supply pipe 324. The air circulation unit body 321 is provided with a first air supply port, a second air supply port, and a third air supply port. The first air supply pipe 322 is connected to the air supply port of the backrest 120 and the first air supply port, respectively. The second air supply pipe 323 is connected to the seat cushion air supply port 3114 and the second air supply port, respectively. The third air supply pipe 324 is connected to the lifting stimulation mechanism 210 and the third air supply port, respectively. It will be understood that the air circulation unit body 321 is configured to output an air flow with an appropriate temperature, wind speed, and flow rate. The air flow is distributed internally and outputted from the first air supply port, the second air supply port, and the third air supply port, respectively. This allows the temperature of the seat cushion, back, and leg areas to be independently adjusted, thereby further improving comfort.

[0050] In some embodiments, a heat dissipation vent 325 is provided on one side of the air cycle unit body 321, and a connection structure 326 is provided at the bottom of the air cycle unit body 321. It will be appreciated that the heat dissipation vent 325 is used to dissipate heat generated by the compressor or internal components during operation, and the connection structure 326 facilitates the installation of the air cycle unit body 321 on the wheelchair frame 100.

[0051] In some embodiments, the connection structure 326 includes a flange and a threaded hole provided on the flange. In other embodiments, the connection structure 326 may also be a commonly used connection structure 326 for snap connection, welding, etc.

[0052] In some embodiments of the present application, the electrical stimulation control component 212 includes an electrical stimulation line 2121 and an electrical stimulation controller 2122. One end of the electrical stimulation line 2121 is connected to the electrical stimulation controller 2122, and the other end of the electrical stimulation line 2121 is provided with an electrical stimulation patch 2123. It is understood that the electrical stimulation controller 2122 is used to control the effect of the electrical stimulation. When in use, the electrical stimulation patch 2123 is attached to the patient's leg at the location to be treated, thereby combining different frequencies of electrical stimulation (FES) to perform multimodal coincident stimulation of the lower limbs.

[0053] In some embodiments of the present application, the rehabilitation air flow component 211 includes a rehabilitation air circulation plate, which is provided with a rehabilitation air inlet for diffusing the air flow output by the air circulation mechanism 320. Designing the rehabilitation air flow component 211 to include the rehabilitation air circulation plate not only facilitates installation and maintains a simple structure, but also ensures that the air flow is fully distributed over the patient's legs.

[0054] In some embodiments of the present application, the lifting stimulation mechanism 210 further includes a bracket 214 and a strap assembly 215. The rehabilitation air circulation plate and strap assembly 215 are disposed on the bracket 214. The lifting component 213 includes a driver 2131, a lifting pedal 2132, and a telescopic rod assembly 2133. The lifting pedal 2132 is fixedly connected to the bracket 214. The driver 2131 is used to drive the telescopic rod assembly 2133 to extend and retract. The telescopic rod assembly 2133 can drive the lifting pedal 2132 to rise and fall by extending and retracting, so that the electrical stimulation control component 212 and the bracket 214 are lifted synchronously. It is understood that the bracket 214 serves as an installation base to facilitate the installation of various parts around the patient's legs. The strap assembly 215 is used to fix the patient's leg position to ensure the treatment effect. The driver 2131 drives the telescopic rod assembly 2133 to extend and retract to adjust the position of the lifting pedal 2132, thereby driving the patient's leg movement to achieve treatment.

[0055] In some embodiments, the telescopic rod assembly 2133 includes an inner rod and an outer rod, which are assembled via a threaded connection. The driver 2131 is configured as a click, which controls the telescopic movement by driving relative rotation between the inner and outer rods. In other embodiments, the telescopic rod assembly 2133 can be configured as a pneumatic telescopic rod, with the driver 2131 configured as a cylinder, which can also achieve a lifting effect.

[0056] In some embodiments of the present application, the audio-visual display mechanism 220 includes a display screen 221 and an adjustable support rod 222. One end of the adjustable support rod 222 is movably mounted on the wheelchair frame 100, and the other end of the adjustable support rod 222 is movably connected to the display screen 221, so that the display screen 221 can be adjusted in three dimensions. It is understood that the display screen 221 can display animations and issue voice announcements, thereby cyclically stimulating the lower limbs through the lifting device to produce a rehabilitation effect, while combining electrical stimulation and visual and auditory stimulation to perform multimodal lower limb rehabilitation. The adjustable support rod 222 is used to flexibly adjust the position of the display screen 221, thereby facilitating use.

[0057] In some embodiments, the adjustable support rod 222 includes a telescopic rod body and a swing head with multiple universal joints. The swing head is also provided with a clamping component capable of clamping the display screen 221. The adjustable support rod 222 can be used to adjust the position of the display screen 221 in three dimensions.

[0058] Understandably, with the rapid development of brain-computer interface technology, it is widely used in the field of rehabilitation. Currently, existing rehabilitation technologies for stroke patients are mainly based on physical rehabilitation methods, which have a single rehabilitation method and single stimulation parameters, and are limited in scope of application. Furthermore, the rehabilitation process requires a certain period of sitting still and concentrating attention. Therefore, the comfort of the rehabilitation process and the patient's attention also greatly affect the overall rehabilitation effect.

[0059] In some embodiments of the present application, a program controls a controllable motor to provide assisted lifting somatosensory stimulation, controls the electrical stimulation controller 2122 to provide microcurrent leg stimulation for lower limb rehabilitation, and controls the display to play a leg-lifting animation and the phrase "Imagine lifting your legs" for visual and auditory stimulation. An air circulator delivers adjustable-temperature air to the mesh seat and mesh backrest 120, and the rehabilitation device maintains continuous air circulation, ensuring the patient's comfort is the same as during initial rehabilitation. The double-layer mesh seat and backrest 120 are elastic. Finally, an EEG cap collects EEG signals in real time and analyzes energy changes in the signals to further adjust the parameters of the controllable motor and the electrical stimulation controller 2122, thereby achieving efficient rehabilitation. By designing a lower limb rehabilitation system based on brain-computer interface technology, the lifting device provides cyclical stimulation of the lower limbs, producing a rehabilitation effect. Multimodal lower limb rehabilitation is achieved by combining electrical stimulation with visual and auditory stimulation. The multi-parameter lower limb rehabilitation equipment provides lower limb rehabilitation for stroke patients, further increasing the diversity and scope of rehabilitation. By designing a double-layer mesh seat cushion, a double-layer mesh backrest 120, and an air circulation plate for the rehabilitation device, the double-layer mesh elastic structure and the addition of an air circulation plate between the seat cushion and the backrest 120 allow for continuous internal air circulation, improving comfort during quiet and prolonged sitting, relieving fatigue, and promoting better nerve conduction between the legs and the body. This allows the patient to focus more on visual and auditory stimulation rather than being distracted by the pain caused by sitting still or for long periods of time, ensuring normal lower limb rehabilitation training and further improving rehabilitation results.

[0060] Reference Figures 1 to 8 The device of the second embodiment of the present application includes the lower limb rehabilitation equipment of the first embodiment of the present application, and also includes a control device, a monitoring device when worn, etc. The patient is evaluated and rehabilitated by designing a multimodal stimulation brain-computer interface system, and a pneumatic hydraulic pump is used to lift the lower limb rehabilitation device to different degrees to achieve somatosensory stimulation rehabilitation. The paralyzed lower limbs are stimulated and rehabilitated at different frequencies by an electrical stimulation device fixed to the wheelchair frame. Under the stimulation combination of the above two, a visual and auditory stimulation module is designed to perform somatosensory stimulation, electrical stimulation, and visual and auditory stimulation on the legs to achieve the effect of multimodal stimulation, and by improving the double-layer seat mesh cover and the back mesh cover, the rehabilitation device air circulation plate, and the temperature-controllable blower to transmit air flow of appropriate temperature to the double-layer seat mesh cover and the back mesh cover, the rehabilitation device air circulation plate transmits, thereby maintaining the overall comfort during the rehabilitation process, so that the attention can be better focused on visual and auditory stimulation during rehabilitation, achieving an immersive rehabilitation effect, and better promoting nerve conduction in the body's legs, thereby achieving comfortable multimodal stimulation rehabilitation.

[0061] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
