The bionic cough simulator is applied to patients with invasive mechanical ventilation. It assists patients with effective expectoration by simulating actual coughing mechanism of human being. The unique air path and algorithm design provide seamless compatibility with ventilators. Features of the bionic cough simulator include avoidance of injury, more effective sputum drainage, and automated operation. Coughing is a protective respiratory reflex of human that serves the purpose of cleaning up secretions or foreign matters in respiratory tract. After a complete inspiration cycle is delivered by the ventilator to a patient receiving invasive ventilation, the bionic cough simulator will be activated immediately. By simulating the coughing mechanism of human being, it generates a brief and large air flow, which enables direct drainage of sputum out of the human body from the main airway and bronchi in an expiration cycle. The unique design of airway and algorithm ensures synchronous operation with the mechanical ventilation system without interfering with normal function of the ventilator. Expectoration is one of the main nursing tasks for patients with mechanical ventilation. Effective expectoration is the key to prevent airway obstruction and maintain the success of mechanical ventilation. Ventilator-associated pneumonia（VAP） is the most common and fatal complication in mechanical ventilation patients with a incidence of 43.1%, a mortality rate of 51.6%, so timely and effective expectoration plays an important role in preventing and controlling infection .
