A chest physiotherapy system of a patient.

Along with the development of the industry, many pollutants are emitted from factories and automobiles, and as a result, the number of lung disease patients is increasing.

Many studies are being conducted on efficient treatment methods for these lung disease patients.

As is well known, the treatment of patients with lung disease has a lot of limitations in improving the patients' activity impairment in the case of simple drug treatment. Therefore, in combination with drug treatment, breathing is performed by comprehensive rehabilitation treatment such as chest physiotherapy and psychotherapy. It is subsidizing.

The respiratory rehabilitation treatment includes position drainage therapy, breathing exercise and relaxation exercise.

Patients with respiratory rehabilitation can benefit greatly from removing bronchial secretions, alleviating bronchial stiffness, and expanding lung tissue, improving breathing patterns and learning to control breathing, increasing motor skills, and performing daily life movements. Will increase.

In particular, respiratory exercise is one of the necessary treatments to increase the alveolar ventilation by correcting the breathing pattern and strengthening the respiratory muscles, and to increase the cough function to release the secretions in the airways.

In order to increase the alveolar ventilation, training of increasing muscle strength and endurance of the respiratory muscles is required.

In order to increase the coughing ability to remove secretions, strength training of aerobic muscles is required.

In other words, both inhalation breathing and exhalation breathing should be performed to restore the function of lung disease patients or to reduce postoperative respiratory complications.

Among the inspiratory breathing exercises, for inhalation muscle training, a variety of inspiratory resistive breathing apparatuses can be used by the individual to conveniently perform respiratory muscle training.

There is no proper apparatus for training, and many classical methods such as candle blowing and bottle blowing are used.
