The Closed Wound Drainage Kit contains three essential parts: a silicone bulb, silicone drains, and a stainless steel trocar. It is widely utilized as a post-operative drain for the effective collection of bodily fluids from surgical sites. The drains are available in both flat and round forms in various sizes, with both the bulb and drains manufactured from high-quality medical-grade silicone.

This kit creates a negative pressure state at the suction head, allowing external materials to be squeezed toward the head, thereby completing the suction effect. It is suitable for clinical use in medical drainage, expectoration, and the management of sewage blood and secretions.

The Clinical Process: Wound drainage reservoir → Negative pressure drainage → Debridement → Promotion of wound healing (reducing patient pain).
