Abstract
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.

38. 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 in fluid communication with one another; a tube relief lumen valve in fluid communication with the tube relief lumen; a suction pump in fluid communication with the tube drainage lumen; and a controller in communication with the tube, wherein the controller is programmed to actuate the suction pump at a first level of suction which maintains the tube relief lumen valve in a closed configuration and at a second level of suction which reconfigures the tube relief lumen valve to an open configuration, wherein the second level of suction is communicated to the tube relief lumen valve via the tube drainage lumen to open the tube relief lumen valve. - View Dependent Claims (39, 40, 41, 42, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60)
