Abstract
A relatively flexible, dual-lumen enteral feeding tube for delivery of fluid through a patient's esophagus to the patient's digestive system, the enteral feeding tube having proximal and distal ends. The tube comprises an enteral feeding lumen having a feeding lumen inlet opening adjacent the proximal end of the tube and a feeding lumen outlet opening adjacent the distal end of the tube. Additionally, a relatively small stylet lumen is provided separate from said enteral feeding lumen, the stylet lumen having a stylet lumen inlet opening adjacent the proximal end of the tube and being longitudinally co-extensive with a substantial length of the enteral feeding lumen. A relatively stiff stylet having a tapered annealed distal portion is removably positioned in the stylet lumen and extends from the stylet inlet lumen opening to adjacent to the feeding lumen outlet opening. A Y-site adaptor is fixed on the proximal end of the tube and the stylet is shorter in length than the distance from either of the Y-site openings to the tube outlet opening. To facilitate insertion or removal of the stylet, which is constructed of metal, into or from the stylet lumen, a portion of the stylet is pr…
