Suction machine bottle (also called a suction canister) is a medical collection container used with a suction machine to safely capture and hold fluids removed from a patient during procedures. It connects to the suction unit and collects mucus, blood, saliva, or other bodily secretions drawn through tubing while keeping the suction system hygienic and preventing contamination. Made from durable, medical‐grade plastic, the bottle is easy to clean or replace, often marked with graduated volume measurements for monitoring fluid amounts. Designed for use in hospitals, clinics, emergency rooms, dental clinics, and home care settings, it’s an essential accessory for airway suctioning, post‐operative care, and respiratory support.
