Abstract

A self-contained, independently operable closed wound suction evacuator which is comprised of a box-like internal body structure disposed within a fluid tight, flexible outer pouch. The pouch includes an inlet/outlet valve for providing communication between the interior of the pouch and the atmosphere of the interior of the pouch and a drainage tube. The box-like internal body structure is capable of being in an engaged position or in a disengaged position. In the disengaged position, the internal box-like structure can remain in a flat condition without causing the tensioning member to be stretched or activated. When ready for use, the internal structure can be manually expanded into its box-like structure. When fully expanded the internal structure will become engaged, hence engaging the tensioning member. Subsequent compression of the internal structure to its flat position stretches the tensioning member and activates the evacuator. Upon subsequent release of the compressive force, the tensioning member will cause the internal structure to expand back into its box-like shape, hence developing a vacuum within the evacuator to draw fluid through a drainage tube and into the evacuator. The flexible pouch expands as the internal body structure expands.
