ABSTRACT:
A control module for regulating the flow of gases in a suction drainage apparatus. The drainage apparatus includes a collection container in communication with a body cavity to receive body fluids (including liquids and gases) therefrom and a suction source for creating a negative pressure within the collection container and removing the gases of the body fluids. The control module includes a serial arrangement of chambers and a plurality of flow control means in a unitary compact structure which fits within a recess provided in the collection container. The control module is adapatable to different sizes and types of collection means and does not add appreciably to the overall size of the device. Baffle means are provided to prevent the loss of the indicator liquid from the air leak indicator means if the device is tipped in any direction.
