The Closed Wound Drainage Kit consists of three primary components: a silicone bulb, silicone drains, and a stainless steel trocar. It is widely utilized as a post-operative drainage system for collecting bodily fluids from surgical sites. The drains are available in various forms, including flat and round designs, in multiple sizes. Both the drains and the bulb are manufactured from high-quality medical-grade silicone.

This kit functions by creating a negative pressure state within the suction head. This "suction" effect efficiently draws materials into the head for effective removal. It is primarily used across clinical departments for medical drainage, expectoration, and the removal of sewage blood or secretions.

By facilitating negative pressure drainage, the kit assists in wound debridement, which is a critical step in promoting faster wound healing and reducing patient discomfort during the recovery process.
