Anatomic Illustration

We are a medical device company that is developing disposable devices for mechanical ventilated patients (closed suction systems and endotracheal tubes). We would like to create series of simple illustrations to be used in presentations that explain one of the main advantages of our closed suction system over our competitors. The first illustration should show a human trachea, the second will show that same trachea with an endotracheat tube inside, the third illustration will show the endotracheal tube with biofilm and secretion buildup. The objective is to demonstrate how narrow the patient's airway becomes during mechanical ventilation.
