An inlet port is in fluid communication with the collection chamber for receiving the fluid. A one-way valve is in fluid communication with the collection chamber for preventing air from entering the patient from the inlet port. A vacuum control chamber has a lower end and an upper end in fluid communication with the one-way valve. A flexible conduit has a first end fluid communication with the exterior of the apparatus and a second end movably positioned within the vacuum control chamber. Elevation adjustment apparatus connected to the flexible conduit is provided for moving the second end of the flexible conduit upwardly and downwardly to various positions within the vacuum control chamber and is activatable from the exterior of the chest drainage apparatus. A suction outlet port for communicating with a source of vacuum is in fluid communication with the vacuum control chamber.
