Abstract: A fluid collection bag is disclosed which has a corrugated foam opening support. The foam support is placed continuously around the opening to automatically keep the fluid collection bag in the correct open position. The corrugations on the foam support allow for continuous fluid accumulation and/or drainage. A solid foam bar is also utilized as an opening support. The foam bar is specifically shaped to continuously force the fluid collection bag into the proper open position. A pressure sensitive adhesive layer is placed on the bottom of the bag to keep the fluid collection bag in the proper positon on the patient, and to maintain a fluid imprevious seal between the surgical site and the patient and/or medical staff.
