ABSTRACT:
A naso-gastric tube for removing fluids from a patient's stomach is provided and comprises an elongated tube having a first end and a second end which is adapted for insertion into the patient's stomach. The tube has a plurality of apertures adjacent the second end for providing communication between the patient's stomach and the vent and suction passages of the tube. Cushions or balloons are mounted on the tube adjacent the apertures and are adapted to be inflated so as to protect the apertures from occlusion by the lining of the stomach. The cushions are deflated prior to the tube member being inserted into and removed from the patient's stomach.
