ABSTRACT:
A unique colostomy or ileostomy bag includes an anti-back flow member provided by a thin plastic tube. The structure of the thin plastic tube reduces any likelihood of waste contacting a patient's skin. The thin plastic tube has a relatively large opening compared to a seal positioned adjacent the patient. Thus, any waste passing through the seal tends not to contact the thin plastic member adjacent an entrance to the thin plastic member. Rather, the waste contacts the thin plastic member at a downstream position. At the downstream position, any waste on the thin plastic member would not be adjacent to patient, and would tend to not contact the patient. The thin plastic member has relatively little rigidity such that it presents little resistant to flow of the waste material between the sides of the thin plastic member. In this way, the waste moves easily between the sides of the thin plastic member and into a bag for storage. In further features of the invention, belt loops are positioned on each side of the bag to assist in carrying the bag on a patient. Further, various structures for rolling and securing the bag such that the bag may be periodically opened for removable of waste are also disclosed.
