drainage tube
Surgical fluid exit
A drainage tube is a medical device inserted into a body cavity or wound to remove excess fluid, blood, or pus.
Surgeons place drainage tubes after operations to prevent fluid buildup and promote healing.
The tube typically connects to a collection bag or bulb that creates gentle suction: The nurse emptied the drainage tube twice a day.
