1. Suction tube can be inserted into nasal cavity and oral cavity, and simulated sputum can be suctioned.
2. Suction tube and Yanken tube can be inserted into trachea and bronchia through nasal cavity or oral cavity. And trainers can observe the interior operation and simulate intubation and suction.
3. Suction tube can be inserted into trachea and bronchia through tracheotomy cannula. And trainers can observe the interior operation and simulate intubation and suction.
4. By taking off one half of the face, the intubating position can be confirmed, and the anatomical structures of nasal cavity, pharynx, oral cavity and cervix can be learned. The trainers can exercise suction skill under straight observation, and improve the effectiveness of the training.
5. The simulating sputum can be put into nasal, oral cavity and trachea, which can enhance the lifelike feel of the suction training
