A closed wound drain is a medical device that removes excess fluid from a surgical site through a tube connected to a collection reservoir. The system creates gentle suction to prevent fluid buildup that could cause swelling, infection, or delayed healing. Common types include Jackson-Pratt drains with squeezable bulbs and Hemovac drains with spring-loaded reservoirs. It’s important to keep these drains secure and protected as they can easily catch on doorknobs, furniture, or clothing during daily activities, which is why a specialized pouch like the C.U.D.D.L. Pouch helps protect them during your recovery.
