Chest Drain Valve is a medical accessory used in conjunction with pneumothorax aspiration catheters to aid in the natural re-expansion of the lung. If incomplete expansion of the lung persists after mechanical aspiration of air, the one-way valve connected to the catheter prevents inadvertent backflow of air into the pleural space. This simple accessory set is an effective solution for patients suffering from pneumothorax and requires minimal effort to use.
