Abstract
A plastic bag for collecting discharges via a drain, especially from operation wounds, from, e.g., the thoracic and abdominal cavities. The bag is somewhat similar to an ostomy bag but differs in that a portion of its front wall has an increased surface area and reduced material thickness by being processed to form a film blister. This blister area allows a grip on the drain protruding into the bag through an aperture in its rear wall. The grip provided by the blister area makes it possible to manipulate the drain, notably to pull it gradually out from the body, without exposing the operation wound to any risk of infection.
