ABSTRACT:
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 the atmosphere, and an inlet providing commuication 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.
