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.

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.

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.

An apparatus for placement of a chest tube includes a chest tube assembly and an advancing mechanism configured to move the chest tube assembly. The chest tube assembly includes an outer structure and a chest tube disposed in the outer structure. The chest tube assembly may further include a trocar. The advancing mechanism may include a depth control. A method for using an apparatus for placement of a chest tube includes placing the apparatus against the chest, and advancing the chest tube assembly to a desired depth, wherein the apparatus includes a chest tube assembly and an advancing mechanism configured to move the chest tube assembly, wherein the chest tube assembly includes an outer structure and a chest tube disposed in the outer structure.

A device for clearing obstructions from a medical tube, such as a chest tube, is disclosed in various embodiments. In embodiments, the device features a clearance member that is formed to match a cross-section of a medical tube. Still further, the clearance member can have a plurality of branches, each branch configured to clear a respective lumen in a partitioned region of a medical tube. In this manner, the clearance member may clear obstructions from individual lumens of the partitioned region of the medical tube. Device for actuating a clearance member to clear obstructions within a medical tube are also disclosed. Methods of clearing a medical tube of obstructions are also disclosed.

Disclosed is a chest drainage system which reduces or eliminates pooling of blood/liquid and/or clogging/clotting in the drainage tube and/or chest tube, and provides objective and accurate measures of drained fluid volume and chest air leak. The chest drainage system continuously monitors chest tube and drainage tube status and clears pooled liquid in the drainage tube, and/or a clogged chest tube when necessary to restore negative pressure to the chest.

The present invention is directed to a method and a device for accurately guiding a chest tube to an intended position within a pleural cavity of an animal or human being. There is also provided a kit-of-parts comprising a catheter and a catheter guiding device according to the present invention.

Devices and methods for managing chest drainage include a drainage system with a chest tube having a chest tube drainage lumen and a drainage reservoir in fluid communication with the chest tube drainage lumen. A pump may be in fluid communication with the chest tube drainage lumen and a pressure sensor may be positioned proximal to the chest tube and in communication with the chest tube drainage lumen. A controller may be in communication with the pressure sensor and the pump, wherein the controller is configured to actuate the pump at a first suction level sufficient to drain a fluid from the chest tube drainage lumen. The controller is further configured to actuate the pump at a second suction level which is different from the first suction level such that an absence of attenuation in the second suction level over time is indicative of an obstruction in the chest tube.

This document provides systems and methods that can improve the efficacy of tube and needle thoracostomy. For example, this document provides devices and methods for confirming the proper placement of a chest tube or needle within the pleural space to relieve a pneumothorax or tension pneumothoax.

The invention discloses a chest cavity drainage tube. The chest cavity drainage tube is in a Y shape, and comprises an upper chest tube and a lower chest tube; the upper chest tube and the lower chest tube of the chest cavity drainage tube are positioned in the same tube sleeve in front of the crotch of the Y shape; the cross section of the tube sleeve is elliptical; a separating supporting wall is formed at the position, between the upper chest tube and the lower chest tube, of the tube sleeve; a thin flushing tube used for flushing the chest cavity is arranged in the upper chest tube. According to the chest cavity drainage tube, two incisions which are required to be formed in the chest of a patient when a traditional chest cavity drainage tube is used can be reduced to one incision, so that the pain of the patient and the wound infection rate can be effectively reduced.
