Description

A kind of robot lung rehabilitation training system based on expiratory dyspnea degree feedback
Technical field
The utility model relates to field of medical device, refer to chronic obstructive pulmonary disease people degree of expiratory dyspnea quantification especially, real-time monitoring also instructs recovery exercising robot assisting patient to carry out respiratory convalescence training based on this biomechanical information, improves the training interdependence of patient.
Background technology
Chronic obstructive pulmonary disease (COPD) is the third-largest lethal cause of disease in the whole world, and it not only causes patient's physiological function and quality of life and has a strong impact on, and adds admission rate and the death rate, brings tremendous economic to bear to family and society.Due to generally declining and the impact of the factor such as habits and customs of urban air-quality in recent years, in China more than 40 years old crowd, the incidence of disease of COPD is 8.2%, occupies China's cause of the death second, every year therefore sick lethal number more than 1,000,000 people.The lower degradation factor of the substantive damage of COPD patient lung, alveolar and small airway elastical retraction ability makes gas be stranded in lung, causes the generation of excessively inflation, thus makes patient be easy to have difficulty in breathing; Simultaneously, due to the decline of respiratory muscle strength, and pathological change caused by compensatory adaptation SAO, patient Yi Fasheng height maincenter respiratory drive state is to maintain effective ventilation, and between respiration drive and expiratory dyspnea sensation, there is positive correlation, namely the enhancing of respiration drive can make patient produce dyspneic sensation, and it is the cardinal symptom of this disease.
Training is the unique method of COPD patient lung rehabilitation except drug therapy.Sports training method mainly by reducing the lactic acid growing amount in respiratory in muscle fibre blood, and improves the harmony of human body daily exercise muscle, ventilation demand when therefore it can reduce patient's peak exercise.Up-to-date clinical research shows, training can make patient be unlikely to occur the enhancing of respiration drive when carrying out equality strength amount of exercise, namely avoid the quickening occurring respiratory rate as far as possible, thus dysfunction of ventilation is alleviated, effectively alleviate expiratory dyspnea during patient's peak exercise.Secondly, training can make the structure and fuction of musculature, nervous system improve to the regulatory function of musculature and cardiovascular function, thus improves the exercise tolerance of patient, to alleviate the caused expiratory dyspnea of motion.In addition, training can make the muscular strength of respiratory muscle strengthen, and the enhancing of muscular strength is associated with the decline of respiration drive, thus the expiratory dyspnea degree of patient is declined.
Although numerous research show training for improve patient respiratory difficulty and PFT play key effect, but because patient has existed the pathological condition such as limited, the high ventilation demand of ventilation and excessive inflation, and more easily occur in these situations of training initial stage, thus force patient to refuse to participate in training.Clinical research shows to adhere to that the COPD patient of training is only 1%, and the improving physiological function that the interruption of training can make training obtain progressively falls the state to rehabilitation training after rise.Gradual respiratory muscle strength training and assist type train the mode of this Absorbable organic halogens training compliance more and more to be praised highly in recent years.But, at Real-time Collection human body respiration dynamic information and feed back patient respiratory degree of difficulty robot assisted training research in, rare successful clinical practice example, its main cause can be summarized as: (1) cannot the expiratory dyspnea degree of Real-time Feedback and quantification patient, clinical in patient respiratory difficulty assessment mainly employing subjective sensation evaluation at present, lack the fusion of accurate model by non-intrusion measurement data to the real-time analysis of the smooth breathing degree of COPD patient and computational methods, for rehabilitation auxiliary robot provides feedback, and for patient and doctor provide the Rehabilitation Assessment parameter of quantification, (2) the friendly interaction problems solving athletic rehabilitation machine people and COPD patient is needed, due to the space height intersection of robot and patient, robot will carry out motion capture to patient different limbs basis muscular strength, thus the auxiliary strength giving different limbs different completes limb motion with assisting patients, so lack force information in real-time and accurate human body, comprising joint moment, joint power, joint energy and muscle tone etc., affecting being the obstacle that robot applies at lung clinical rehabilitation.(3) the quantification training prescription of stable patient motion training compliance is lacked clinically, if the parameters such as the whole-body muscle exercise tolerance of Patients with Chronic Obstructive Pulmonary Disease individuality and expiratory dyspnea degree can be realized and the design of healing robot training program is merged, stable patient motion training compliance will be contributed to, and provide theoretical foundation for medical personnel formulate patient's gradual lung rehabilitation training scheme.
