A single-use irrigation, suction and drainage catheter is used during medical procedures to irrigate wounds, aspirate fluid, or drain secretions. It is made from sterile material to avoid cross-infection and is intended for surgery, wound treatment, postoperative care, and related settings. Its design generally uses multiple lumens so that irrigation and drainage can be performed together. Core functions include irrigation, which delivers saline or another irrigation solution to a wound or body cavity to clean the area and remove necrotic tissue or contaminants, and suction, which uses negative pressure to remove fluid, blood, or secretions to maintain a clear operating field or reduce infection risk.
