Aerosal Delivery- High Frequency Chest Wall Oscillation (HFCWO)- Negative Pressure Secretions Collection.
Aerosel Delivery is generated by compressor, the diameter of atomizing powders can reach 1-5µm to accelerate mucus removing.
High Frequency Chest Wall Oscillation simulates the cough of human by rapidly homogeneously inflating and deflating the vest. Retained secretions will be removed by the shear force of the cough airflow or helped by negative pressure collection.
Negative Pressure Secretions Collection is using the vacuum principle to suck the secretions from oral cavity and trachea.
