An integrated chest evacuation tube that is specifically configured for being a closed system when inserted and retained inside of a chest cavity provides enhanced benefits over the state of the art. The integrated chest evacuation tube generally includes a valve that is made up of a hollow elastomeric housing having a collar at an output end of the housing which provides an aperture into the housing, a valve input end at an input end of the housing, and an elongated slit at the valve input end. The slit is configured to close together in a spring-like manner when in a closed position. The valve is integrated and at least partially inside of a chest evacuation tube that has a tube inlet port and a tube outlet port. The tube inlet port is adapted to drain fluid and/or air from a human chest cavity. With the collar fixedly attached to the chest evacuation tube at essentially the tube outlet port, the elongated slit is adapted to be opened by a hollow tube when the hollow tube is forcibly pushed through the slit from a direction of the collar.
