Abstract
A portable closed wound drainage system that uses a pouch shaped dressing which is inserted into a wound. At least a portion of the outer surface of the pouch is porous to allow exudates to enter. Exudates are removed from the pouch by flexible tubing which is secured inside the pouch at one end and secured at the other end to a portable drain/suction unit. The pouch contains porous material. The tubing can have a single or multi-lumen structure. The pouch and the tube are sealed by a flexible sealing material which is applied to the outer surface of the skin. A cosmetic cover sheet is attached to the patient's skin over the closed wound drainage system.
