Abstract
An inflatable oral-nasal gastric tube constructed with double walls allowing the tube to be stiffened by inflation for purposes of initial placement in the patient, and deflated thereafter in order to minimize internal tissue irritation and necrosis. The tube comprises thin flexible outer and inner substantially cylindrical walls which are sealed together at their proximal and distal ends to form an inflatable structure, with a lumen defined inside the inner wall. The lumen is throughgoing and communicates with a funnel attached to the proximal end for administration of food and/or medicine and a weight is attached at the lower distal end to aid in initial placement efforts. A valve and air tube are provided on the proximal end of the tube to inject and withdraw fluid between the inner and outer walls of the tube.
