ABSTRACT:
A stoma drainage appliance having a fluid collecting pouch constructed of sheets of flexible material with two internal sheets sealed together at spaced intervals to provide a valve across the center of the pouch precluding upward flow of fluid between the two internal sheets. There is at least one unsealed space between the seals located so as to provide a direct, straight path from an inlet opening of the upper section of the pouch to the lower section of the pouch. The stoma drainage appliance further includes an outlet spout connected at the lower section of the pouch. The spout has a tapered opening with an inlet neck section of oval cross-section and an outlet end section of circular cross-section. The spout is made of flexible material for clamping along the neck section to close the spout and includes a cap for attachment to the end section thereof. A tubular coupling member is provided for connecting to the spout and it has an opening of tapered construction to accommodate external conduits of varying size.
