The invention is a novel drainage tube system, to be used following surgery, where drainage is necessary. It comprises a protective shield of spherical segmental configuration, having a recessed flat surface on one side and a spherical surface on the other side. In a modification, the flat surface is omitted and the spherical segment is open. An internal drainage tube penetrates the shield and terminates externally thereof on the spherical side in tube connector means comprising a bulbous portion spaced from the spherical side of the shield and a threaded portion intermediate the bulbous portion and spherical side. This enables fluid-tight connection with the internal tube for the external drainage tube sufficient even for the application of a pump, if necessary, but admitting of ready removal for inspection or patient transfer. Gauze or other absorbent dressing material, conforming in configuration to the bottom side of the shield, includes a central opening to accommodate the internal tube and a split from the opening to the edge to facilitate dressing application and change. The dressing is held in place against the body by the shield, in turn taped firmly in place to anchor the tubes and protect the opening while maintaining the dressing intact. The apparatus may be assembled or pre-cast integrally, as a disposable kit, from soft, flexible material.
