Enteral feeding tube with separate stylet lumen

摘要

A relatively flexible, dual-lumen enteral feeding tube (10) for delivery of fluid through a patient's esophagus to the patient's intestinal tract is provided having an enteral feeding lumen (22) and a relatively small stylet lumen (24) separate from the enteral feeding lumen (22) and longitudinally co-extensive with a substantial length of the enteral feeding lumen (22). The stylet lumen (24) has a removable relatively stiff metal stylet (85), the stylet (85) with a tapered annealed distal portion. The stylet (85) has a coating of polytetrafluorethylene and a coating of silicone over the polytetrafluorethylene. The tube (10) also has a Y-site adaptor (16) fixed on the proximal end of the tube (10). The Y-site adaptor (16) has Y-site openings through which access may be had to the enteral feeding lumen (22).
