High frequency oscillation pneumatic expectoration machine 

The Chest Expectoration Machine is a medical device used to help patients with respiratory diseases remove sputum. The Oscillating Expectoration Machine uses airflow vibrations generated by high-frequency oscillation to stimulate the patient's respiratory tract and promote the loosening and discharge of sputum. Expectoration Machine usually consists of an oscillator and connecting tubes. The oscillator produces high-frequency oscillations that deliver airflow to the patient's airway. Connecting tubes deliver airflow to the patient's mouth or nasal cavity. The patient enters the airflow through breathing, and the oscillating airflow stimulates the respiratory tract, helping to loosen and expel sputum. Whole Chest Oscillating Expectoration Machine has the following advantages: 1. High-frequency oscillation can effectively stimulate the respiratory tract and promote the loosening and discharge of sputum. 2. The operation is simple and patients can receive treatment at home. 3. No need to…
