Thoracic Chest Drainage Bottles are disposable medical devices used to safely drain air, fluid, or blood from the pleural space. They maintain a one-way flow to prevent backflow into the chest, utilizing a “water seal” mechanism. In more advanced systems (double- or three-chamber), additional chambers can enhance suction control, fluid collection, and patient safety.
