Technical Field

The utility model belongs to breathe and recovered equipment field, in particular to wearable recovered noninvasive ventilation system of breathing.

Background

The recovery period of the acute failure or the recovery period after the acute attack of the chronic respiratory failure needs respiratory rehabilitation treatment so as to recover the respiratory function to the maximum extent, enable the acute respiratory failure patient to reach the respiratory level before the disease as much as possible, reduce the respiratory disability rate or reduce the permanent damage degree of the respiratory function; meanwhile, the respiratory rehabilitation therapy can also enable the chronic respiratory failure patient to recover the respiratory function level before the acute attack as much as possible, delay the progress of the chronic respiratory failure and ensure the life quality and the self-care capacity of the patient in daily life. Current common methods of such respiratory rehabilitation therapy include: 1. exercising and recovering some respiratory muscles or respiratory movements, such as pursed lip breathing, abdominal breathing, etc., in the hospital bed or ward with the help and knowledge of the medical staff; 2. impedance respiratory load training, namely using various respiratory training appliances to generate certain respiratory resistance and properly increasing respiratory load so as to perform respiratory training or training; 3. aerobic respiration exercise, namely, carrying out proper activities and exercises as well as respiratory muscle exercise and respiratory training under the condition of oxygen inhalation. Although the methods have certain effects, the methods have respective limitations, the breathing load intensity of bare-handed breathing training is limited, the impedance breathing load training lacks aerobic support, and the current aerobic breathing exercise cannot provide breathing work support for patients and cannot perform larger breathing exercise activities.
