A suction machine, also known as an aspirator, is a type of medical device that is primarily used for removing obstructions — like mucus, saliva, blood, or secretions — from a person's airway.
Suction machines work on the principle of negative pressure that creates a vacuum effect to pull out secretions from a person's oral cavity. To create this negative pressure, several components of the suction machine work in conjunction. These include Vacuum pump, which causes negative pressure.
