The surgical drain tube of the present invention is comprised of a tubular member of a flexible pliable material. The tubular member has a oval exterior surface and a collapsible wall which defines a lumen which is normally of a substantially oval cross section. A tongue member is integrally formed with the inner surface of the top wall portion of the tubular member and extends the longitudinal length of the lumen. Oppositely deposed from the tongue member is a groove member which is formed integrally with the inner surface of the bottom wall portion of the tubular member and also extends the length of the passageway.
