Description

Rehabilitation device suitable for stroke patient

Technical Field

The utility model relates to a be adapted to apoplexy patient's rehabilitation equipment, be adapted to the corresponding motion training of apoplexy patient and other personnel that have corresponding demand.

Background

There are approximately 1630 million people worldwide each year who have a stroke and, after the stroke, have varying degrees of hemiplegia, which is the second leading factor leading to permanent disability and death. Today, stroke is still continuously increasing every year, and the number of strokes is estimated to increase to 2300 million people every year in 2030. In stroke populations, approximately 6450 thousands of patients remain with varying degrees of disability, requiring bystanders to assist their activities of daily living. Because the recovery process of the apoplexy patient is long and needs to be attended by a rehabilitation doctor in real time, the care of the apoplexy patient not only causes great burden to a medical system, but also brings great influence to the family life of the apoplexy patient.

Researchers have conducted extensive studies on the possibility and possible mechanisms of functional recovery following central nervous system injury. The existing research and clinical data show that: the theory that the structure and function of the central nervous system can be reorganized and regenerated under appropriate conditions after the central nervous system is damaged is called plasticity theory of the brain, whether adult mammals or non-mammals. The plasticity of the central nervous system is an important theoretical basis for rehabilitation training and functional recovery after the central nervous system is damaged. The therapeutic mechanism of stroke is based on two hypotheses, one of which considers that in the symmetrical brain, a small portion of which is damaged, commands can be sent from the symmetrical undamaged brain to the motor neurons via different paths of transmission; another hypothesis is that the damaged proximal part of the brain may replace the lost function and complete the motor command. There are many factors that affect brain plasticity, and studies suggest that a large amount of functional recovery training is an important external promoter, whether in the early, middle, and late stages of injury. The special function training is indispensable in the function recovery process after the central nervous system is damaged, and the early intervention rehabilitation training can not only maintain the joint activity, prevent the muscular atrophy, but also obviously improve the final rehabilitation degree of the motor function of the patient.

As can be seen from the above, rehabilitation is particularly important for stroke patients. After a stroke, the patient takes a lot of time for rehabilitation therapy. Various researches show that the rehabilitation therapy can improve the dyskinesia of patients to a great extent and lead the life of the patients with apoplexy to be more independent and independent. There are many methods for rehabilitation of stroke patients, including physical therapy, task therapy, nerve promotion technology, biofeedback therapy, acupuncture and massage therapy, and motor therapy, among which motor therapy is one of the important therapeutic means of rehabilitation medicine. According to statistics, about 80% of stroke patients have dyskinesia sequelae, so the most important part in rehabilitation treatment is the recovery of the motor function of the patients, so that the joint mobility of the patients is maintained or further improved; increase muscle strength and promote the recovery of the activity function of the affected limb; reducing or eliminating muscle atrophy caused by the disuse limb; improving the coordination of movement, improving the daily life ability, and the like.

At present, the motor rehabilitation of related people usually needs a rehabilitation doctor to manually assist the injured limb of a patient to do corresponding exercise, or the family members of the patient need to assist the patient to do exercise from the side after the patient is discharged. Because a large number of same actions are required to be repeated in the rehabilitation process, a rehabilitation doctor and a assistant often feel fatigue, the labor intensity is high, the time consumption is long, and a plurality of patients do not have corresponding conditions in practice, so the rehabilitation efficiency is influenced greatly. Some studies have shown that similar effects to those of conventional treatments can be obtained by using a rehabilitation device for treating stroke, and although the rehabilitation device may never completely replace a rehabilitation physician from a clinical point of view, the rehabilitation device can help the rehabilitation physician to reduce the burden to a great extent, and can also alleviate the problem that a patient is difficult to receive regular treatment due to uneven distribution of medical resources, lack of rehabilitation knowledge, and the like.

However, the existing exercise apparatus is not designed for rehabilitation exercise training, the exercise intensity is relatively large, especially, a necessary passive exercise mode is lacked, and the related rehabilitation exercise training requirements cannot be met.

On the other hand, modular joints are developed and widely used in the manufacture of robots, and these modular joints can be understood as revolute pairs (or revolute pairs) provided with a prime mover and various motion detection sensors, and can simulate the motion mode of relevant joints of a human under the control of a control system, so that the modular joints can be used to realize quick lap joint of a mechanical arm or a robot. The modular joint is provided with a standardized or normative power and signal cable and wiring structure, can utilize the existing software system to control the movement, and provides favorable conditions for the development of a passive movement training device.
