Abstract
An apparatus for draining a biological substance from a collection bag attached to a patient. The apparatus includes a large bore, thin walled drainage tube which expands to have a substantially circular cross-sectional configuration when a biological substance such as fecal material passes therethrough, and collapses into a substantially flat cross-sectional configuration when the tube is empty. A connector in the form of two adhesively coated, resilient, fluid impervious pieces of sheet material is used to connect the large bore drainage tube to the collection bag.
