ABSTRACT OF THE DISCLOSURE An evacuator system comprising a compressible container inside of which is positioned a vacuum assist device. The vacuum assist device aids in the expansion of the container and in developing a vacuum in the container upon expansion. The vacuum assist device within the evacuator acts to maintain a substantially constant level of vacuum as the evacuator expands while drawing fluids from a closed wound and collecting the fluids in the evacuator container. The evacuator includes an outlet for providing communication between the interior of the container and a drainage tube. The evacuator may include a novel valve mechanism which enables the evacuator to be activated, held in an activated position until needed, and then released from the held position for use to draw fluid from a patient.
