Device includes a flexible, hollow tube portion having a resiliently deformable mushroom shape tip at the inner end thereof to retain the tube in the stomach or other viscera of a patient and provide an enlarged internal chamber for the mounting of a one-way flapper valve therein and the seating of the flapper valve against the inner end of the tube portion to prevent reflux of gastric contents while permitting the influx of fluids into the stomach or other viscera of the patient through the tube portion. A pair of oppositely extending, relatively short, flat wings are integrally molded on the outer end of the tube portion to make the tube portion self-retaining and flush up against the skin. The wings are relatively narrow in width, whereby the tube portion may be rotated a part turn to bring the wings into contact with different areas of the skin if irritation should occur. A plug is integrally molded on the outer end of one of the wings by a flexible membrane which permits the plug to be inserted into the tube at the outer end thereof and removed therefrom as desired.
