plastic bag for collecting fluids via a drain, including surgical damage, and running, for example, thoracic and abdominal cavities. the bag is somewhat similar to a bag of ostomie but differs in the fact that a part of the front wall has an increased surface area and reduced in thickness due to the formation of a film tube.this region is the tight grip of the drain protruding to the inside of the pocket through the opening in the rear wall. thus, it is possible to manipulate the drain, in particular for the phasing out of the body without exposing the lesion or any risk of infection.
