DEVICES AND METHODS FOR MANAGING CHEST DRAINAGE

The present invention relates to a drainage system, comprising a tube configured for insertion into a body of a subject, wherein the tube defines a tube relief lumen and tube drainage lumen which are fluidly coupled to one another via an opening defined within a proximal portion of the tube, wherein the tube relief lumen and tube drainage lumen extend through the proximal portion separately from one another such that the opening is in proximity to one or more drainage openings defined along the tube, whereby the opening is positioned within the body of the subject when the tube is inserted into the body during use, and further comprising a tube relief lumen valve in fluid communication with the tube relief lumen such that a pressure differential is formed between an ambient pressure and the tube relief lumen, wherein the tube relief lumen valve is configured to close at a first pressure differential and to open at a second pressure differential which is different from the first pressure differential.
