Abstract: A coaxial draining tube, particularly for chest draining systems, includes an inner tube, which has a first opening, and an outer tube, which has a second opening. The inner tube is enclosed within the outer tube and has a smaller diameter than the second opening of the outer tube. The first and second tubes are mutually coupled by way of a supporting component and include one or more holes adapted to allow the passage of air from the chest cavity to the first opening of the inner tube and one or more holes adapted to allow the passage of liquids from the chest cavity to the second opening of the outer tube. The one or more holes are provided in the portion of the coaxial draining tube that is intended to be inserted in the chest cavity of a patient.
