ABSTRACT:
Disclosed is a chest drainage collection system including a suction control container, a water seal container, and at least one collection container. A first passage provides communication between the collection container and a patient's pleural cavity for communicating air and/or liquid to the collection container. A second passage provides communication between the seal container and the collection container. A third passage communicates between the suction control container and the seal container. A fourth passage communicates between a source of vacuum pressure and the water seal container. A float is disposed in the lower end of a tube in the water seal container to provide visual identification that the system is operational. A baffle overlies the water in the suction control container to preclude water entrainment and consequent water loss. The fourth passage contains a check valve for automatically sealing the fourth passage when the fourth passage is exposed to atmospheric pressure.
