A single bottle (or single jar) suction machine is a medical device designed to remove fluids, mucus, blood, or secretions from a patient's airway or body cavity. It features one collection bottle (usually 1L to 2L capacity), an electric or manual vacuum pump, an adjustable pressure regulator, and a vacuum gauge. These units are lightweight, making them highly ideal for home care, small clinics, dental setups, and ambulances.
