Fushan Closed Wound Drainage Kit contains three essential parts: the silicone bulb (reservoir), silicone drains, and a stainless steel trocar. It is commonly utilized as a post-operative drain for effectively collecting bodily fluids from surgical sites. The drains are available in both flat and round forms in varying sizes. Both the drains and the bulb are manufactured from high-quality medical-grade silicone.

The kit functions by creating a negative pressure state within the suction head. This allows materials outside the suction head to be squeezed toward it, completing the "suction" effect. This system is widely used across clinical departments, primarily for medical drainage, expectoration, and the removal of sewage blood and secretions.

By utilizing negative pressure drainage, the kit assists in debridement, which is crucial for promoting faster wound healing and significantly reducing patient pain during the recovery process.
