Drainage tubes can help relieve the pressure of fluid accumulation in the body, prevent infection and promote wound healing. They are usually made of soft material, with one end inserted into the body and the other end connected to a fluid collection bag or suction device to drain the accumulated fluid in the body. After surgery or other treatments, medical drainage tubes are very important auxiliary tools that can help patients recover faster.
