Abstract
Abstract A collection pouch for receiving drainage from an abdominal opening following surgery comprising a flexible fluid-tight bag having a lateral opening adapted to register with the abdominal opening, means for sealing the bag to the abdomen around the registered openings in the abdomen and the bag, and means for venting the bag under controlled circumstances to exhaust gases which may have unpleasant odors. In one form of the invention, a vent aperture is provided in the bag for exhausting gases, together with releasable means adhesively secured to the bag to close the vent aperture in a manner which permits removal of the releasable means to vent the bag in privacy and replacement of the releasable means to again close the vent aperture. In another form, a vent aperture is provided in the bag for exhausting gases, and a filter is secured to the bag adjacent the vent aperture for deodorizing the gases exhausted through the aperture.
