Description
Technical Field
The invention relates to the field of medical equipment, in particular to an auxiliary rehabilitation device for a apoplexy hemiplegia patient.
Background
Stroke (cerebral stroke) is a common neurological disorder, which is mainly characterized by sudden rupture or blockage of cerebral blood vessels, resulting in interruption of blood flow to specific areas of the brain, thereby affecting the corresponding neurological function. One of the sequelae of stroke is hemiplegia, i.e. a damaged muscle function on one side of the patient's body, which affects not only the walking ability of the patient, but also the self-care ability of his activities of daily living.
Functional recovery of the affected lower limbs of hemiplegic patients is an important aspect of the stroke rehabilitation process, as walking ability and standing stability are critical to patient independence. For hemiplegic patients, flexion-adduction training and flexion-abduction training are two key rehabilitation exercises that are of particular importance for the motor and functional recovery of the lower extremities.
Training of adduction of knee bending
The adduction training of the knee is mainly directed to the medial thigh muscle groups, which provide the necessary support and stability while walking and standing. This training helps:
Enhancing muscle strength: by repeated adduction movements, the muscles inside the thigh, in particular the vastus medial muscle, are enhanced, which is critical to improving the stability and efficiency of walking.
Improving motor coordination: adduction training helps to improve neurological communication between the brain and the affected lower extremities, improving motor coordination and control.
Promoting neurological recovery: through target-oriented exercise training, the neural plasticity of the damaged area in the brain is promoted, and the sensory and motor functions of the affected lower limb are recovered.
Training for abduction of knee bending
The main goals of flexion and extension training are the muscle groups outside the thighs, including gluteus maximus and gluteus medius, which are important for maintaining pelvic stability and supporting lower limb movements. The effects of this training include:
Increase muscle strength: abduction training helps the patient to increase muscle strength in these areas by activating and strengthening the outer muscles of the thighs and buttocks, which is important for improving walking stability and preventing falls.
Improving balance capacity: by strengthening the outer leg muscles, abduction training helps to improve the balance of the patient and reduce jolts during walking.
Facilitating cross-brain area connection: abduction training facilitates communication and coordination between different areas of the brain that control limb movement and balance, facilitating overall recovery of brain function.
The two training methods work together in the rehabilitation process of stroke patients by enhancing lower limb muscle strength, improving nerve control and coordination ability, and promoting regeneration and repair of damaged nerves.
Because hemiplegia patient is difficult to overcome the gravity of affected limbs and perform basic rehabilitation actions such as adduction and abduction of knees, the existing hemiplegia patient is generally assisted by personnel, which not only increases the labor cost, but also reduces the quantity of rehabilitation actions of the hemiplegia patient for a long time, thereby being difficult to achieve theoretical rehabilitation effect. In addition, the hemiplegia patient has inconvenient movement, so the hemiplegia patient needs an auxiliary device which has a simple structure and is easy to operate and can assist the hemiplegia patient to independently perform basic rehabilitation actions such as abduction, adduction and the like. However, the existing auxiliary device has the disadvantages of complex structure, more electronic elements, difficult operation, and incapacity of guaranteeing the safety, and is not friendly for the independent operation and rehabilitation of the hemiplegia patient, which is a person with very inconvenient actions.

Wherein the inner diameter of the middle part of the metal guide short cylinder is larger than the inner diameters of the two ends; the outer diameter of the middle part of the magnetic head is smaller than the inner diameter of the middle part of the metal guide short cylinder and larger than the inner diameters of the two ends of the metal guide short cylinder; the outer diameters of the two ends of the magnetic head are smaller than the inner diameters of the two ends of the metal guide short cylinder.
Scheme II: the difference with the first scheme is that a sliding column is fixed on the inner side of the repulsive magnet; the opposite surfaces of the extrusion massage heads and the repulsive magnet are provided with sliding holes corresponding to the sliding columns; the sliding column is in sliding insertion fit with the sliding hole; a spring is connected between the sliding column and the sliding hole, so that the opposite surfaces of the extrusion massage head and the repulsive magnet are separated in a static state; the opposite surfaces of the extrusion massage heads and the repulsive magnet are correspondingly provided with electrodes; the repulsive magnet is close to the extrusion massage head under the action of pressure and enables the two electrodes to be in electrical contact so as to close a circuit; the circuit supplies power to the extrusion massage head, so that the extrusion massage head directly electrically stimulates the patient or the extrusion massage head heats to thermally stimulate the patient.
Scheme III: the difference from the first or second proposal is that the first binding belt is provided with an integral arc-shaped guide rail with a non-circular section; the guide rail extends to the upper part of the repulsive magnet of the first binding band from one side far away from the second binding band; a plurality of suction magnets are sleeved on the guide rail in a sliding way; the plurality of suction magnets are flexibly connected in series; one surface of the attraction magnet, facing the repulsive magnet on the first binding belt, is in homopolar repulsion with the opposite surface of the repulsive magnet, and one surface of the attraction magnet, facing the repulsive magnet on the second binding belt, is in opposite attraction with the opposite surface of the repulsive magnet; one end of the suction magnet, which is far away from the second binding belt, is fixedly connected with the second binding belt through an elastic pull rope, and one end of the suction magnet, which is close to the second binding belt, is fixedly connected with one side of the second binding belt, which is far away from the suction magnet, through a non-elastic pull rope; when the second binding band is far away from the first binding band, the attraction magnet is pulled to the position above the repulsive magnet of the first binding band through the inelastic pull rope.
For the first to third schemes, the first binding band and the second binding band are both in a band shape, and the two ends of the first binding band and the second binding band are respectively provided with a magic tape structure or a snap fastener structure.

After the training is completed, the first binding band and the second binding band are taken down.
The invention has the following beneficial effects:
1. the invention provides an auxiliary rehabilitation device for a hemiplegia patient with apoplexy and a lower limb rehabilitation training method thereof, which aim to promote the recovery of the lower limb functions of the hemiplegia patient after the apoplexy:
promoting recovery of muscular strength and motor coordination
The physical acting force generated by the repulsive magnet assists the patient to perform the training of adduction and abduction of the knee, and the muscles of the lower limb of the affected side, including the key muscle groups such as quadriceps femoris, biceps femoris and gluteus maximus, can be effectively stimulated. The stimulation is helpful for improving muscle strength, increasing muscle endurance, improving exercise coordination of patients, and is important for restoring walking and standing ability.
Improving nervous system function
The auxiliary rehabilitation device can promote the re-education and functional recovery of the sensory nerves by directly stimulating the skin of the affected lower limb through the extrusion massage head and combining the electric stimulation or the thermal stimulation. This sensory feedback is very important for the neuroplasticity of the cerebral cortex, helping to improve the sensory and motor functions of the patient, promoting repair and functional reconstruction of the nervous system.
Enhancing the perceptibility of the lower extremities of a patient
Through electric stimulation or thermal stimulation of the lower limbs on the affected side, the perception capability of patients on the lower limbs on the affected side can be effectively improved. This enhanced perceptibility is important to prevent neglect of symptoms (e.g., unnoticed to the affected side body parts), to enhance the patient's self-awareness and use of the affected side lower extremities.
Improving rehabilitation efficiency and patient participation
The design of the rehabilitation device allows the patient to perform rehabilitation training independently at home or in a rehabilitation center under the guidance of professionals, so that the convenience and accessibility of rehabilitation are improved, and the participation degree and rehabilitation power of the patient are improved. Through repeated training, the patient can intuitively feel the rehabilitation progress, thereby enhancing the rehabilitation effect.
Safety and applicability
The rehabilitation device design considers the safety and comfort of the patient, and ensures that the device can be firmly and comfortably fixed on the lower limb of the patient through an adjustable binding band and a magic tape or snap fastener structure. In addition, the design of repulsive force magnet and attractive force magnet ensures the stability and effect in the training process, and is suitable for the rehabilitation requirements of hemiplegia patients with different degrees.
In conclusion, the auxiliary rehabilitation device and the training method provide a comprehensive, effective and safe lower limb function rehabilitation scheme for the apoplectic hemiplegic patient, and are expected to obviously improve the rehabilitation quality and the life quality of the patient.
2. The invention provides an innovative rehabilitation training method for apoplectic hemiplegia patients by the principle of the like poles repel of the magnets, in particular to the aspects of reducing the self gravity influence of the lower limbs on the affected side and promoting the movement capacity of the lower limbs on the affected side. Hemiplegia caused by stroke often greatly weakens the strength of lower limbs on the affected side of a patient, and even can not overcome the gravity of the patient to independently complete basic actions such as knee bending, adduction, abduction and the like. Without external assistance, these basic and important rehabilitation actions may be difficult for the patient to perform, limiting the progress and effectiveness of rehabilitation.
Action of principle of repelling like poles of magnet on reducing influence of gravity
Providing antigravity support: the like repulsion of the repulsive magnets in the device provides an effective external force which can help to counteract part of the gravity of the lower limb on the affected side, so that the patient can more easily perform the knee bending adduction and abduction actions. This antigravity support is particularly important for patients with extremely reduced strength of the affected lower extremities, as it can relieve the burden on the affected extremities, enabling the patient to begin basic rehabilitation training.
Enhancing muscle activity: by reducing the effects of gravity, the patient may be more focused on performing the action using a particular muscle group rather than striving to overcome the force of gravity of the affected lower limb. Thus, not only can the activity of a specific muscle group be improved, but also the coordination and strength of muscles can be improved.
Facilitating recovery of motion control capabilities: with the help of the repulsive magnet, the patient can control the movement track and amplitude of the affected lower limb more accurately, which is important for restoring the movement control capability and the movement precision. In this way, the patient can learn stepwise how to independently control the affected lower limbs, thereby improving the ability to perform daily activities.
In conclusion, the influence of the gravity of the lower limb on the affected side is effectively reduced by the principle of the like poles of the magnet, and an effective method capable of independently performing the knee bending adduction and abduction training is provided for the apoplectic hemiplegic patient. The method is not only helpful for improving the exercise capacity and muscle strength of the patient, but also promotes the improvement of the self-confidence of the patient and the active participation in the rehabilitation process.
3. According to the specific embodiment of the invention, through the combination of magnetic force change and the adduction and abduction actions of the knee bending, the action of extruding the massage head is driven, and the unique design ingenious and the beneficial effects in rehabilitation treatment are shown:
Magnetic force combined with mechanical movement: by arranging the repulsive magnet and the extrusion massage head in the rehabilitation device, the interaction between magnetic force and mechanical motion is skillfully utilized. The principle of the like poles of the magnets is changed when the patient performs the inward folding or outward unfolding action of the knee bending, and the change directly drives the movement of the extrusion massage head, so that the purpose of physical treatment is realized, and external electric power or a complex mechanical structure is not needed.
Automated treatment process: in the process of rehabilitation training of a patient, the action of extruding the massage head is automatically synchronous with the action of the patient, and no additional operation is needed. This automated treatment process simplifies the rehabilitation training and allows the patient to focus more on the performance of rehabilitation actions.
Advantageous effects
Promoting muscle activation and blood circulation: the action of squeezing the massage head can imitate the manual massage, directly act on the affected lower limb, help to activate muscles, promote blood circulation and facilitate the repair of damaged tissues in the rehabilitation process. This physical stimulus has a positive effect on relieving muscle stiffness, preventing muscle atrophy, etc.
Enhancing sensory feedback: for patients with post-stroke hemiplegia, the sensory function of the affected lower extremities is often affected. The action of squeezing the massage head provides a strong sensory stimulus which helps to restore the sensory function of the affected lower limb, enhancing the patient's perception and control of the affected limb by improving the sensory feedback of the nervous system.
Improving recovery efficiency: the present invention makes the rehabilitation training process more efficient because it combines active exercise and passive stimulation. The comprehensive effect ensures that the patient obtains additional treatment stimulation while finishing the rehabilitation action, thereby accelerating the rehabilitation process.
4. The invention realizes the closing of the circuit of the extrusion massage head in the knee bending adduction and abduction actions by utilizing the change of magnetic force, and shows an innovative rehabilitation technology integrating physical therapy and electric stimulation therapy. The design has obvious beneficial effects, and also embodies high innovation and ingenious:
design ingenious nature
Seamless integrated electrical stimulation: the electric stimulation technology is skillfully combined with physical rehabilitation training, and whether the circuit is closed or not is directly controlled through magnetic force change, so that an external power supply or complex electronic equipment is not needed. The design utilizes the strength generated by the rehabilitation action of the patient to convert the rehabilitation action into the electric stimulation in the treatment process, thereby realizing the self-driven electric stimulation treatment.
Dynamically responsive stimulation: the closure of the circuit is closely related to the specific actions of the patient, so that the electric stimulation is ensured to be sent out synchronously with the rehabilitation training of the patient. Such dynamic responsive stimulation means that the intensity and timing of the electrical stimulation can be automatically adjusted according to the actual actions of the patient, providing a personalized treatment regimen.
Advantageous effects
Promoting neuromuscular activation: electrical stimulation has a significant effect on activation of the neuromuscular system, especially in terms of promoting muscle contraction, enhancing muscle strength and improving motor coordination. By the electrical stimulation synchronized with the rehabilitation action, the muscle group of the affected lower limb can be activated more effectively, and the recovery of the neuromuscular function can be accelerated.
Enhancing sensory feedback: in addition to promoting muscle activation, electrical stimulation can provide important sensory feedback, helping the patient to enhance the perception of the affected lower extremities. This sensory feedback is critical to improving the patient's self-perception, reducing sensory deficit, and increasing the efficiency of rehabilitation training.
Improving rehabilitation power: by integrating the electrical stimulation, the instant feedback is provided for the patient, and the feedback not only promotes rehabilitation on the physiological level, but also enhances the participation and the power of the patient on the psychological level. The patient can intuitively feel the stimulation effect brought by each action, thereby participating in rehabilitation training more actively.
Optimizing a rehabilitation path: by self-driven electrical stimulation, a more efficient and personalized rehabilitation path is provided for the patient. Compared with the traditional passive rehabilitation method, the active participation mode can adjust the treatment scheme according to the specific condition and the needs of the patient, so that the rehabilitation process is more in line with the individual difference.
In conclusion, the closing of the circuit of the extrusion massage head is realized through magnetic force change, so that not only is the diversity and effectiveness of rehabilitation training increased, but also the neuromuscular activation and sensory feedback are improved through electric stimulation, and the rehabilitation process of a stroke hemiplegia patient is accelerated. The design fully displays the interdisciplinary integration force, and brings an innovative treatment method to the stroke rehabilitation field.
5. The invention skillfully utilizes the inelastic stay cord and the elastic stay cord, combines the attraction force and the repulsion force of the magnet, and creates a dynamic force adjusting system in the abduction and adduction actions of the knee bending. The design not only embodies the ingenious application of the physical principle, but also has obvious beneficial effects in clinical rehabilitation training:
Dynamic force adjustment: the non-elastic pull rope is linked to gradually pull the suction magnet when the knee is bent and abducted, and the suction magnet is returned by the elastic pull rope when the knee is bent and adducted, so that the dynamic adjustment of the force between the two lower limbs is realized. The regulation mechanism naturally and smoothly meets the requirement of rehabilitation training of patients, and the training process is more in accordance with the physiological movement rule.
Intensity of adaptive training: the training intensity is adaptively adjusted through a physical mechanism, a complex electronic control system is not needed, manual intervention is not needed, and a simple, convenient and effective rehabilitation mode is provided for patients. The self-adaptive capacity ensures that rehabilitation training is safe and efficient, and is particularly suitable for patients with different rehabilitation stages and individual differences.
Strengthen muscle strength and coordination: through changing suction force and repulsive force in the knee bending abduction and adduction actions, the patient can be prevented from the lower limbs of the affected side from striking the lower limbs of the healthy side due to the weakness of the patient in the knee bending adduction actions, and simultaneously, the lower limbs of the affected side from outwards deviating from the highest point due to the weakness of the patient in the knee bending abduction actions can be prevented from falling and sprain;
Promoting neurological recovery: dynamic force variation stimulation can enhance the response of the nervous system, promote repair of damaged nerve pathways and development of neural plasticity. This is critical for the recovery of neurological function in post-stroke hemiplegic patients.
The safety of rehabilitation training is enhanced: the training intensity is naturally regulated through a physical mechanism, so that excessive training and potential injury risks are avoided, and the safety of the rehabilitation process is ensured.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, for stroke patients, flexion-extension training and flexion-extension training are two key rehabilitation exercises that are of particular importance for lower limb locomotion and functional recovery. Stroke (cerebral stroke) generally causes a loss of muscle function on one side of the patient's body, called hemiplegia, affecting the patient's walking ability and activities of daily living. The two training methods can effectively help patients to improve the motor coordination and muscle strength of the lower limbs on the affected side and promote the recovery of nerve functions:
Training of adduction of knee bending
The adduction training of the knee is mainly directed to the medial thigh muscle groups, which provide the necessary support and stability while walking and standing. This training helps:
Enhancing muscle strength: by repeated adduction movements, the muscles inside the thigh, in particular the vastus medial muscle, are enhanced, which is critical to improving the stability and efficiency of walking.
Improving motor coordination: adduction training helps to improve neurological communication between the brain and the affected lower extremities, improving motor coordination and control.
Promoting neurological recovery: through target-oriented exercise training, the neural plasticity of the damaged area in the brain is promoted, and the sensory and motor functions of the affected lower limb are recovered.
Training for abduction of knee bending
The main goals of flexion and extension training are the muscle groups outside the thighs, including gluteus maximus and gluteus medius, which are important for maintaining pelvic stability and supporting lower limb movements. The effects of this training include:
Increase muscle strength: abduction training helps the patient to increase muscle strength in these areas by activating and strengthening the outer muscles of the thighs and buttocks, which is important for improving walking stability and preventing falls.
Improving balance capacity: by strengthening the outer leg muscles, abduction training helps to improve the balance of the patient and reduce jolts during walking.
Facilitating cross-brain area connection: abduction training facilitates communication and coordination between different areas of the brain that control limb movement and balance, facilitating overall recovery of brain function.
The two training methods work together in the rehabilitation process of stroke patients by enhancing lower limb muscle strength, improving nerve control and coordination ability, and promoting regeneration and repair of damaged nerves.
Embodiment one: referring to fig. 2 and 3, an auxiliary device for rehabilitation training of the lower limbs of a patient with hemiplegia after stroke is designed to comprise two main parts: the first part is a strap (hereinafter simply referred to as "first strap 1") that is adjustable and easily attachable to the unaffected (healthy side) lower limb of the patient, and the second part is a strap (hereinafter simply referred to as "second strap 2") that is also adjustable and easily attachable to the affected (affected side) lower limb of the patient. The two straps are each equipped with a mutually exclusive magnet unit (repulsive magnet 3) which, when placed on the corresponding lower limb, provides a unique resistance by virtue of its repulsive nature, to facilitate the patient's specific rehabilitation exercise action.
In a more detailed design of the device, the second strap 2 is equipped with a series of metal guide stubs 4 penetrating the strap, inside which a slidable magnetic head 41 is provided. The repulsive magnet 3 is fixed to the outer side of the magnetic head 41, and the squeeze massage head 42 for applying pressure is arranged to the inner side thereof, which is designed to enhance the sensing ability of the patient to the affected lower limb by physical stimulation.
In addition, the inner diameter of the middle part of the metal guide stub 4 is designed to be wider than that of both ends so that the magnetic head 41 can freely slide during the rehabilitation training of adduction and abduction while ensuring that the moving range of the magnetic head 41 is effectively limited within a safe range. The binding belt adopts a belt-shaped design, and the two ends of the binding belt are provided with magic tapes or buckle structures which are convenient to adjust and fix.
When the lower limb rehabilitation training is carried out, the patient needs to fix the first binding belt 1 and the second binding belt 2 near the knees of the lower limbs at two sides respectively, so that the magnets on the two binding belts are ensured to be positioned at the corresponding positions. Subsequently, the patient lies on his side and bends his knee, and the magnet of the affected lower limb approaches or moves away from the magnet 3 of the healthy lower limb by the training action of adduction and abduction, thereby driving the magnetic head 41 to slide along the metal guide cylinder 4 and applying pressure to the skin by pressing the massage head 42. The series of actions not only help to strengthen the coordination of muscles and nerves, but also enhance the perception of the affected limb by the patient through pressure stimulation of the skin, thereby promoting rehabilitation. After training is completed, the patient can easily detach the two binding bands.
Embodiment two: with reference to figures 4 and 5 of the drawings,
In a further design of the rehabilitation device, the physical stimulation applied to the patient's limb is enhanced by introducing an advanced mechanical structure in combination with the electrical stimulation function. Specifically, a sliding column (abbreviated as sliding column 31) is fixed inside the repulsive magnet 3, and a sliding hole (abbreviated as sliding hole 421) corresponding to the sliding column 31 is provided on the pressing massage head 42 opposite to the repulsive magnet 3. The sliding column 31 is connected with the sliding hole 421 through sliding fit, and the sliding column 31 and the sliding hole 421 are connected through a spring 422, so that the extrusion massage head 42 is kept at a certain distance from the repulsive magnet 3 when no external force acts.
In addition, the opposite surfaces of the extrusion massage head 42 and the repulsive magnet 3 are provided with electrodes, and when the repulsive magnet 3 approaches the extrusion massage head 42 under the action of external force, the two electrodes come into contact, thereby closing the circuit. The closing of this circuit not only provides electrical energy to the squeeze massage head 42 so that it can directly apply electrical stimulation to the patient, but also allows the squeeze massage head 42 to generate heat, further enhancing the patient's perception and rehabilitation of the affected limb by thermal stimulation.
The design skillfully combines two rehabilitation methods of physical and electric stimulation, and realizes automatic activation of electric stimulation or thermal stimulation in specific rehabilitation training actions through precise matching of mechanical structures. The combination method not only enhances the rehabilitation training effect, but also provides a more comprehensive treatment scheme for patients, and is helpful for accelerating the recovery of neuromuscular functions.
Embodiment III: referring to fig. 6 to 8, embodiment three is based on embodiment one or two:
In further perfecting the design of the rehabilitation device, an innovative guide rail system is introduced to enhance the assistance of rehabilitation training for patients. Specifically, the strap for the lower limb of the healthy side (i.e., the first strap 1) is provided with an integrally curved guide rail 5, the cross section of which is designed to be non-circular, so as to ensure that the elements on the guide rail 5 can move smoothly on a designated path. This rail 5 extends from the side remote from the patient side lower limb strap (i.e. the second strap 2) above the repulsive magnet 3 on the first strap 1.
The guide rail 5 is provided with a plurality of attracting magnets 51, and the attracting magnets 51 are connected in series with each other by a flexible material, and are capable of freely sliding on the guide rail. These attracting magnets 51 are designed to achieve a dynamic adjustment of the repulsive magnets 3 on the first strap 1 so that they can achieve a repulsive or attractive magnetic force when facing the repulsive magnets 3 of the second strap 2, depending on the specific relative position. To adjust the position of the suction magnet 51 on the guide rail 5, a double-pull-cord system consisting of an elastic pull cord 52 and a non-elastic pull cord 53 is used. One end of the elastic pull rope 52 is fixed on the second binding band 2, while the other end is connected to the end of the attraction magnet 3 far away from the second binding band 2, and the inelastic pull rope 53 is fixed on the end of the attraction magnet 51 near the second binding band 2 and fixedly connected with the side of the second binding band 2 far away from the attraction magnet 51.
During the abduction action of the rehabilitation training, the second binding band 2 synchronously pulls the attraction magnet 51 to move along the guide rail 5 under the action of the inelastic pull rope 53, overcomes the elastic force provided by the elastic pull rope 52, and gradually moves the attraction magnet 51 to the position above the repulsive force magnet 3 on the first binding band 1. This dynamic adjustment mechanism allows the original repulsive force to be converted into attractive force during the training process, further promoting the patient to make more accurate rehabilitation actions.
Through the exquisite design, the rehabilitation device can dynamically adjust magnetic force interaction according to the action and force application condition of a patient, and more personalized and effective rehabilitation training support is provided for the patient. After training is completed, the patient can easily remove the first and second straps, simplifying the use and management of the device.
