1. An enteral feeding tube for adminstration and aspiration of fluids within the gastrointestinal tract, the tube having a wall of selected thickness, a proximal end of the tube for joining to a fluid nutrient source, a distal end of the tube comprising:

  • a non-collapsible bolus, a proximal end of the bolus in fluid communication with the tube, a terminal end of the bolus being sealed, the bolus containing at least one opening defining a tube outlet, the bolus having an outer diameter generally at least as large as the outer diameter of the tube, the bolus further including;

    (a) side walls, a portion of the side walls being lowered and upwardly facing to define the opening, the lowered side wall portions having a transverse sectional height equal to at least the inner diameter of the tube; and

    ,(b) an upwardly curving inner bolus floor, the floor gradually channeling the fluid to the opening, the curvature of the floor being defined by an arc circumscribed from a, radius having a length equal to at least five times the inner diameter of the tube,whereby the recessed side walls and upwardly curving floor of the bolus prevent occlusion of the tube outlet and permit a fluid flow through the tube outlet substantially approximating fluid flow through an open-ended tube.
