Abstract

A chest drainage system includes a collection device and a fluid pathway configured to extend from the collection device to a patient. A pressure source is configured to selectively provide sub-atmospheric pressure to the fluid pathway. The system is configured to introduce sub-atmospheric pressure from the pressure source at a substantially constant target pressure and at a dynamic pressure that varies from the target pressure. A method is also disclosed for draining a pleural cavity of a patient. The method involves applying dynamic pressure to the pleural cavity of a patient by changing sub-atmospheric pressure applied to the patient such that the patient's pleura moves without any or limited patient activity, thus facilitating removal of loculated fluid from the pleural cavity. The method may involve the use of the chest drain system.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority to US Provisional Patent Application No. 61 / 856,427, filed July 19, 2013, which is hereby incorporated by reference in its entirety. technical field [0003] The field of the invention relates generally to medical drainage systems and, more particularly, to chest drainage systems. Background technique [0004] A number of fluid recovery systems have been developed for removing fluid, such as air and / or blood, from a patient. An example of such a fluid recovery system is a chest drainage system. Chest drainage systems are intended to remove fluid from the pleural or mediastinal cavity and restore the sub-atmospheric pressure normally present in the pleural cavity. The system is generally adapted to allow suction to be applied to the pleural cavity to facilitate, inter alia, removal of fluid from the pleural cavity. Once the fluid is removed, the pleural cavity is allowe...
