ABSTRACT A surgical drain is the subject of the present invention. A drain tube is provided with side openings into the tube, "side" being defined relative to the supporting surface. An elongated protective shield is disposed in closely spaced relationship to the openings and extends lengthwise of the tubular member. The protective shield inhibits the entry of loose material which would clog the openings and restrict the flow of fluid. In one type of embodiment, the protective shield comprises a second tubular member disposed in closely spaced relationship to the first tube member. Openings in the second tubular member face the openings in the first tubular member, the latter serving as a protective shield for the second member. In a second type of embodiment, the tubular member is disposed in a serpentine configuration with the openings located in concave stretches along the length of the member. The protective shield comprises a linear element extending lengthwise of the member and contiguous with the convex stretches of the member.
