The Aqua-Seal Chest Drainage Unit is engineered to provide reliable pleural drainage through a wet suction design that helps reestablish and maintain negative pressure within the pleural space. Its three-chamber system includes a collection chamber for visual monitoring of drainage volume and characteristics, a water-seal chamber that functions as a one-way valve and offers insight into pleural activity, and a suction control chamber that stabilizes suction levels for consistent lung re-expansion. Built for clinical dependability, the Aqua-Seal CDU supports efficient postoperative and emergency chest drainage management in critical care settings.
