Design Of Full-Process Rehabilitation Robot For Patients With Lower Limb Dyskinesia

According to the statistical analysis of a large number of data,the base number of elderly people,disabled people and patients with chronic diseases in China is increasing year by year,and the probability of these people suffering from lower limb dyskinesia is extremely high.This situation will lead to a sharp increase in the demand for lower limb rehabilitation nursing,but the number of professional doctors and nurses in China is very short,and patients who need rehabilitation nursing may be in different rehabilitation periods.Traditional artificial rehabilitation treatment is far from meeting the existing needs,and the lower limb rehabilitation robot that can cope with the whole process of patient rehabilitation has become the common desire of patients and doctors.The rehabilitation process of patients with lower limb dyskinesia is complex,which needs comprehensive analysis from multiple angles.Firstly,the rehabilitation process of patients with lower limb dyskinesia involves the different needs of doctors,nurses,patients and their families.Combined with PSD,a comprehensive analysis of the needs of various users is made,and a quality house model for the design of lower limb rehabilitation robot is constructed.Secondly,the functional requirements of lower limb rehabilitation robot are decomposed,and the design matrix of user requirements and functional requirements is constructed by combining AD theory,which is coupled and judged according to independent axiom.Use TRIZ theory to judge and analyze the types of conflicts,and use TRIZ toolbox to solve conflicts.Thirdly,combining with the principle of ergonomics,the size of human body and the range of motion of each joint are analyzed to guide the size design of lower limb rehabilitation robot.Finally,the appearance of the lower limb rehabilitation robot is scrutinized and designed,and the three-dimensional model of the product is constructed.The CATIA human-machine analysis module is used to verify the three-dimensional model by virtual simulation,and the design scheme is further optimized.The whole process robot for rehabilitation of patients with lower limb motor dysfunction can be applied to the whole process of rehabilitation of patients,which can improve the rehabilitation efficiency of patients and reduce the rehabilitation costs of patients and rehabilitation personnel to a certain extent,and has certain positive significance for promoting the development of great health and health care industry.
