A suction machine, also known as an aspirator, is a medical device primarily used to remove obstructions such as mucus, saliva, blood, or secretions from a person’s airway. It operates by creating a vacuum that draws out the unwanted substances, helping to clear the airway and improve breathing. Suction machines are commonly used in medical settings, including hospitals, clinics, and dental offices, to assist in various procedures and emergencies where maintaining a clear airway is crucial.
