A chest tube (chest drain, thoracic catheter, tube thoracostomy, or intercostal drain) is a flexible plastic tube that is inserted through the chest wall and into the pleural space or mediastinum. It is used to remove air (pneumothorax), fluid (pleural effusion, blood, chyle), or pus (empyema) from the intrathoracic space. It is also known as a Bülau drain or an intercostal catheter.

Devices and methods are disclosed for achieving chest drainage in humans or other animals. Chest drainage is often required following traumatic injury or surgery. The devices and methods disclosed herein are especially useful in the emergency, trauma surgery or military setting. The devices utilize a chest tube with a cutting distal end and a central blunt trocar. The blunt trocar or obturator shields the sharp cutting distal end of the chest tube until controllably retracted. Once the blunt trocar or obturator is retracted, the chest tube is advanced out through its sterile, protective package and into the patient. The blunt trocar is advanced back into its position to shield the sharp tip of the chest tube during patient insertion. The chest tube also includes a hold-down mechanism that is created by an adhesive seal to the patient's chest and ribbons or straps that are wrapped around the chest tube once it is correctly positioned. The straps include adhesive ends to grip the chest tube once the straps are in place.

Chest tube drainage system
A system for draining the chest cavity of a patient subjected to a traumatic chest injury and / or to surgery within the chest. The system includes a small, portable suction device and a chest tube with an improved terminal structure. A number of embodiments of the suction device are disclosed; the first (with two variations) a small, completely disposable, bottle-shaped assembly comprising a motor / pump section, a power section, and a desiccant filled chamber, the second (also with two variations) a small box shaped assembly with a disposable desiccant pouch and a power supply that mounts to a battery charger positioned on an IV pole. A number of chest tube terminus structures are disclosed, including multi-lumen structures having high-airflow and low-airflow lumens as well as “dead” and “live” lumens. Fenestrations are variously positioned between and through the lumens in order to collect coagulated components of the extracted fluids and prevent them from clogging the primary flow tube and restricting or preventing continuous airflow.

Methods and devices to clear obstructions from medical tubes
A device for clearing obstructions from a medical tube, such as a chest tube, is disclosed in various embodiments. The device features a shuttle member that is magnetically coupled to a guide wire within a guide tube, through the guide-tube wall, so that translation of the shuttle member induces a corresponding translation of the guide wire within the guide tube, without penetrating or compromising the guide-tube wall. In this manner, when the guide tube is coupled to a medical tube where obstructions have formed, the guide wire and clearance member may be inserted into and withdrawn from the medical tube, via actuation of the shuttle member, to engage and help clear such obstructions from the medical tube without compromising the sterile field. Methods of clearing a medical tube of obstructions are also disclosed.

ActiveUS20110022012A1Easily employedInhibit migrationMedical devicesIntravenous devicesBottleIntensive care medicine
A device for the drainage of a pleural effusion through an operatively engaged chest tube in the chest wall. The device employs a check valve situated between a vacuum source communicating with the chest tube to prevent reversal of the fluid flow out of the patient's body and possible contamination. A valve mounted on a vacuum bottle provides user control of communication of negative pressure from the vacuum bottle to the chest tube. Opening the valve on the bottle communicates negative pressure to the chest tube relative to the pressure in the tube thereby initiating a fluid flow out of the tube and the patient. Once the valve on the bottle is closed, fluid flow ceases and the check valve prevents reversal of the flow.

The utility model relates to a pleural cavity flushing and drainage catheter, which belongs to medical equipment and is suitable for treating patients with empyema. Irrigation and drainage are the most basic treatment methods for empyema. Manual irrigation and drainage through a single chest tube makes the chest cavity susceptible to external infection; short-term bolus injection of irrigation fluid damages the pleura and spreads bacteria; repeated manual operations every day cause pain for the patient. The clinical workload is heavy. The catheterization operation of the present invention is simple; chest flushing and drainage can be performed at the same time, and the catheter can be removed when flushing is not required to continue closed chest drainage; the pipeline is always sealed and one-way drainage to avoid chest infection; sustainable chest flushing and drainage, High clinical curative effect, small workload; suitable for abscess cavities of different sizes.
