The invention belongs to the technical field of medical instruments, and particularly provides a rehabilitation training device for a stroke patient, which applies the characteristics of a segmentation principle, a dilatation fluid and a magnetorheological fluid to the rehabilitation training of limbs of the stroke patient, so that the limbs on two sides of the patient obtain balanced body position and strength rehabilitation training. The force field motion damping effect is applied to protection of a patient, and protection measures and the use convenience degree are improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and specifically refers to a non-linear fluid-based balanced rehabilitation training device for stroke. Background technique [0002] Cerebral stroke, also known as stroke, is an acute cerebrovascular disease characterized by focal neurological deficits. Most stroke patients will leave sequelae such as limb hemiplegia, muscle spasm and atrophy, and aphasia to varying degrees when they enter the rehabilitation period. Among them, limb hemiplegia and muscle spasticity and atrophy are the most common. Most of the existing stroke rehabilitation training methods are artificially assisted training, and a few rehabilitation training equipment can help stroke patients to carry out a certain degree of auxiliary training, but manual assisted training requires a lot of waste. However, the performance of the existing stroke rehabilitation training equipment is relatively single, and the rehabilitatio...

Problems solved by technology

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a stroke balance rehabilitation training device based on nonlinear fluid, aiming at setting simple protection measures for users (convenient for stroke patients), and Due to the contradictory technical problem of not being able to set up simple protective measures (to prevent stroke patients from accidentally causing secondary injuries during use), the force field motion damping load-carrying enclosure frame was creatively set up, and the curved surface principle (using curves) was creatively set up. Parts instead of straight parts) and the force field motion damping effect based on Lenz's law (the magnetic field of the induced current always hinders the change of the magnetic flux causing the induced current) is applied to the all-round protection of the user. The protective structure and copper damping the movement of strong magnets can not only provide comprehensive protection for patients, but also facilitate the use of patients, effectively solving the problem of difficult coordination between protection measures and ease of use; The technical problem of limb balance training for the hemiplegia commonly seen in stroke patients is covered by the standard. The two-way rotation superimposed upper limb balance training walking mechanism and the magneto-rheological fluid asymmetric lower limb balance training mechanism are cleverly set up. Training the walking mechanism applies the principles of segmentation (dividing an object into independent or detachable parts) and dynamic properties (making an immobile object movable, or dividing an object into parts that move relative to each other) to stroke In the balanced rehabilitation training of the patient's upper limbs, the phenomenon of shear thickening of the expansion-plastic fluid is used to provide the equipment with two-way superimposed rotational force, and the patient's rotation control of the equipment is used to achieve the balance training of the patient's upper limb position and strength. Magneto-rheological The liquid asymmetric lower limb balance training mechanism combines the principle of pneumatic or hydraulic structure (replacing solid parts with gaseous or liquid parts), the principle of mechanical system replacement (replacing mechanical fields with electricity and magnetic fields) and magnetorheological fluid (presented when there is no external magnetic field) Low-viscosity Newtonian fluid characteristics, which appear as high-viscosity, low-fluidity Bingham fluid when an external magnetic field is applied) are applied to the balanced rehabilitation training of the lower limbs of stroke patients, using magnetorheological fluid as a semi-linkage material, The patient’s lower limbs can receive balanced rehabilitation training; the technical solution adopted by the present invention effectively solves the inconvenience of using the rehabilitation training device for stroke patients, the inability to perform posture and strength balance training on both sides of the stroke patients, and the need for limb auxiliary treatment for stroke patients. labor-intensive problem
