Description

Medical respiratory muscle training system based on network
Technical Field
The invention relates to the technical field of medical equipment, in particular to a medical respiratory muscle training system based on a network.
Background
Respiratory system diseases are common diseases and frequently encountered diseases, main pathological changes are in trachea, bronchus, lung and chest cavity, cough, chest pain and respiration are affected in light patients, and severe patients are suffered from dyspnea, hypoxia and even respiratory failure to die. Mortality in cities is the 3 rd bit, while in rural areas is the first bit. It should be further appreciated that due to air pollution, smoking, aging population and other factors, the incidence and mortality of chronic obstructive pulmonary disease (chronic obstructive pulmonary disease, including chronic bronchitis, emphysema and pulmonary heart disease), bronchial asthma, lung cancer, pulmonary disseminated interstitial fibrosis, pulmonary infection and other diseases at home and abroad are continuously reduced. Due to factors such as physical and chemical factors and biological factor inhalation caused by air pollution, smoking and industrial economic development, age-aging of population and the like, the incidence rate of respiratory diseases such as lung cancer and bronchial asthma is obviously increased in recent years, and chronic obstructive pulmonary diseases are high (more than 8% in the population over 40 years old).
At present, most respiratory system disease patients need to receive respiratory muscle function training, with the maturity of lung rehabilitation idea and the implementation of lung rehabilitation technology, a hospital urgently needs a respiratory muscle function training device to exercise the respiratory muscle function of the patients, because a person normally inhales, diaphragm contraction and external intercostal muscle contraction, when forcefully inhales, auxiliary muscles need to be inhaled, such as the assistance of trapezius muscles and oblique muscles, the chest is widely lifted as a result of the muscle contraction, the thoracic space is expanded to the limit, and therefore the inspiratory muscles need to be exercised, thereby increasing the strength and tolerance of the respiratory muscle. Inspiratory muscle training is now widely used in chronic obstructive pulmonary patients, and is particularly influential in this particular population due to the weakness of the inspiratory muscles in this population of patients due to chest wall physical abnormalities (excessive pressure breathing due to expiratory airflow limitation) and inadequate effort during high demand ventilation.
The respiratory muscle function evaluation equipment in the market at present works independently, respiratory training is directly carried out on the equipment after evaluation is finished, and the price is high, so that the respiratory muscle function evaluation equipment is not suitable for respiratory training of a large number of patients in hospitals one by one. Still another class of respiratory muscle function training ware is disposable individual use product, can not accurate regulation respiratory resistance, and special person is special, is not suitable for the hospital to carry out the respiratory training, and the regulation mode is manual regulation moreover, and regulation precision and speed all can not reach hospital's operation standard, and most importantly can not the automatic execution training prescription, are not suitable for the hospital to carry out the respiratory training, only are suitable for family expenses.
