A suction machine aspirator pump is a medical device that is used to remove liquids, such as blood, mucus, and other fluids, from a person's body during or after a surgical procedure. It is also commonly used to clear secretions from the airway of a patient who is unable to clear them on their own. This type of pump creates negative pressure through a vacuum, which allows it to suction the fluids and remove them from the patient's body. Suction machine aspirator pumps are most commonly used in hospitals, clinics, and other medical settings.
