The underwater-seal bottle is the key for chest drainage, as it includes a place for drainage to collect and a one-way valve that prevents air or fluid from returning to the chest. Both the one and two-bottle chest drainage systems rely on gravity to create a pressure gradient by which air and fluid leave the chest.

The Romsons  Romo Seal under Water seal Drainage system is used for the following:

• Pleural drainage
• Intercostal drainage catheters
• Cardiac procedures
• Thoracic  procedures
• Management of major, moderate, and minor drainages
• Collection of drainage fluid from the chest cavity
• Suitable for use in all cardiac and thoracic procedures
