Abstract of the Disclosure A collection chamber for fluids and a wide diameter pathway for the removal of air due to leaks from the lung after operation or injury to the contents of the thorax is described. The collection chamber is provided with ports for the attachment of tubing extending from the chest cavity and for connection to a vacuum pump. A water level control vacuum regulator is integral with the chamber which allows a parallel pathway for the removal of large volumes of air from the pleural space without the necessity of a high vacuum. A one-way valve is provided which is open during the drainage mode but which closes during the respiratory inhilation mode to prevent the back flow of air or fluid into the pleural space. In the event of vacuum pump failure, a pressure relief valve is provided to relieve excess positive pressure within the collection chamber. -1-
