How the expectoration function works: It utilizes the clinical treatment principle for coughing and expectoration (Mechanical Inhalation-Exhalation Technique, abbreviated as MIE). It simulates the human cough process by applying a specific positive pressure through the airway, creating a significant volume change in air. The specific curve of airflow allows sufficient entry into small airways, loosening secretions that block various bronchial levels. Then, it rapidly transitions to a negative pressure of a certain magnitude, generating high-speed exhalation airflow to assist in removing sputum.
How the patting function works: It consists of an internal composite high-frequency air oscillator, a vest covering the front, side, and back of the patient's chest cavity, and a gas delivery hose connecting them, allowing the patient to synchronize with the frequency of the composite high-frequency air oscillator.
Working principle of the tapping function: This product is based on clinical chest physical therapy principles. It generates a treatment force with specific directional periodic changes on the human body surface. This targeted treatment force has strong penetration ability and can penetrate the cortex, muscles, tissues, and bodily fluids. The vertical components of this force, which cause tapping and vibration, help relax and liquefy the mucus and metabolites on the respiratory tract mucosa, making them smaller and softer. Another type is the horizontal treatment force parallel to the body surface. Its directed pushing and vibrating effects on the body enable the liquefied mucus in the bronchi to be gradually expelled through the direction of the pushing action.
Working principle of the sputum suction function: It consists of a compressed air pump, a sputum suction tube, and a liquid storage tank. During operation, negative pressure is created inside the tube, which draws the sputum into the liquid storage tank.
