A suction machine, also known as a vacuum extractor or aspirator, is a medical device that is used to remove excess mucus, saliva, blood, and other fluids from a patient's airway or surgical site. It works by creating a vacuum that draws the unwanted materials out of the patient's body through a tube.

 

Suction machines are commonly used in hospitals, clinics, and emergency settings. They can be used for a variety of medical procedures, such as removing excess fluid from the lungs of a patient with pneumonia, clearing a patient's airway during a respiratory emergency, or assisting with the delivery of a baby during a difficult childbirth.
