Chest tube drainage system with analyzer
First Claim
1. A system comprising:
- a chest tube drainage system comprising a first chamber in fluid communication with a port connectable to a chest tube, a second chamber in fluid communication with a port connectable to a suction device, and a fluid seal connected to and disposed between the first chamber and the second chamber;
one or more gas sensors attached to the chest tube drainage system, the one or more gas sensors configured to detect a gas having leaked from a lung into the pleural space, all of the gas sensors of the system configured to detect a gas selected from the group consisting of gaseous carbon dioxide and gaseous oxygen;
a controller connected to the one or more gas sensors; and
at least one indicator coupled to the controller,the controller configured to determine if an upper threshold level of carbon dioxide is exceeded, and to activate the at least one indicator if the upper threshold level of carbon dioxide is not exceeded.

Abstract
A system includes a chest tube drainage system comprising a first chamber in fluid communication with a port connectable to a chest tube, a second chamber in fluid communication with a port connectable to a suction device, and a fluid seal connected to and disposed between the first chamber and the second chamber. The system also includes one or more gas sensors attached to the chest tube drainage system, the one or more gas sensors configured to detect at least one of gaseous carbon dioxide and gaseous oxygen, a controller connected to the one or more gas sensors, and at least one indicator coupled to the controller. The controller is configured to determine if a threshold level of carbon dioxide is exceeded, and to activate the at least one indicator if the threshold level of carbon dioxide is not exceeded.

16. A system comprising:
-
a chest tube drainage system comprising a first chamber in fluid communication with a port connectable to a chest tube, a second chamber in fluid communication with a port connectable to a suction device, and a fluid seal connected to and disposed between the first chamber and the second chamber; one or more gas sensors attached to the chest tube drainage system, the one or more gas sensors configured to detect at least one of gaseous carbon dioxide and gaseous oxygen; a controller connected to the one or more gas sensors; at least one indicator coupled to the controller; and a clamp disposed between the port connectable to a chest tube and the chest tube, and a pressure sensor disposed between the clamp and the chest tube and connected to the controller, the controller configured to determine if a threshold level of carbon dioxide is exceeded, and to activate the at least one indicator if the threshold level of carbon dioxide is not exceeded, the controller is configured to determine if a threshold level of oxygen is exceeded if the threshold level of carbon dioxide is exceeded, and to activate the at least one indicator if the threshold level of oxygen is not exceeded, the controller configured to determine if a threshold pressure is exceeded at the pressure sensor if the threshold level of oxygen is exceeded, and to activate the at least one indicator if the threshold pressure is not exceeded.

17. A system comprising:
-
a chest tube drainage system comprising a first chamber in fluid communication with a port connectable to a chest tube, a second chamber in fluid communication with a port connectable to a suction device, and a fluid seal connected to and disposed between the first chamber and the second chamber; one or more gas sensors attached to the chest tube drainage system, the one or more gas sensors configured to detect at least one of gaseous carbon dioxide and gaseous oxygen; a controller connected to the one or more gas sensors; at least one indicator coupled to the controller; and an oxygen source coupled to the controller, the controller configured to determine if a threshold level of carbon dioxide is exceeded, and to activate the at least one indicator if the threshold level of carbon dioxide is not exceeded, and the controller configured to activate the oxygen source if the threshold level of carbon dioxide is exceeded and a second threshold level of carbon dioxide is not exceeded, and to determine if a threshold level of oxygen is exceeded after the oxygen source is activated, and to activate the at least one indicator if the threshold level of oxygen is not exceeded. - View Dependent Claims (18, 19, 20)
