Abstract: Devices and methods for managing chest or wound drainage are disclosed where in one embodiment, the system generally comprises a chest tube configured for insertion at least partially within a body of a subject, a drainage tube fluidly coupled with the chest tube, a reservoir fluidly coupled with the drainage tube, a pump in communication with the reservoir, and a controller in fluid communication with the drainage tube. The controller may be configured to determine a readiness for removal of the chest tube from the body based upon one or more removal parameters which are obtained over a period of time via the controller.

Abstract: 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.
