Abstract
A drainable ostomy pouch having at least one arcuate spring member, and preferably two such spring members, adjacent the discharge opening at the lower end of the pouch is disclosed. Each wall of the pouch with such arcuate spring member is normally bowed outwardly from the other wall to hold the discharge opening in open condition for draining of the pouch's contents. To seal the discharge opening, the lower end of the pouch is folded upwardly to force the spring member(s) into flattened condition, and the pouch's lower end is then secured in such upwardly-folded condition.
