Cause of closed suction drainage tube obstruction and its prevention using a tube coated on the inside with a silicone gel drug delivery system.
In experimental and clinical studies we showed that obstruction of closed suction drainage tubes is often caused by clots. To prevent this we describe a tube coated on the inside with a silicone gel drug delivery system, which releases anticoagulant drugs. It prevents coagulation and liquefies blood clots present in the tube. This device should thus find application as a tube for continuous suction drainage systems.
