The end of the suction tube was wetted with physiological saline before sucking and then sucked.
Do not take more than 15 seconds each time, if you use it again, it should be separated for 3 minutes to prevent damage to the visceral mucosa.

After the patient's discomfort disappears, the suction tube can be taken out.
