The Closed Wound Drainage Kit consists of three essential components: a silicone bulb, silicone drains, and a stainless steel trocar. This medical device is primarily utilized as a post-operative drain to collect bodily fluids from surgical sites efficiently. The drains are available in both flat and round configurations, offered in various sizes to meet clinical requirements. All drains and bulbs are manufactured from high-quality medical-grade silicone.

This kit creates a negative pressure state at the suction head, allowing external materials to be effectively drawn toward the head to complete the "suction" effect. It is widely applied across various clinical departments for medical drainage, expectoration, and the management of sewage blood or secretions.
