Under Water Chest Drainage System

The Logikal Aus-Seal Chest Drainage System is manufactured in Australia for use as a single bottle system under-water seal thoracic drain. A key feature of the Aus-Seal is the patented Thora Valve incorporated in the screw cap.
By incorporating the Thora Valve positive pressure relief valve, this risk of pressure build up is avoided.
If the air vent tubing became occluded ( kinked, blocked) the subsequent air pressure forces the ball of the Thora-Valve to lift from its seat allowing pressure to escape and preventing any life threatening pressure to build up in the system.
