Gastrostomy tube.

摘要

A replacement gastrostomy tube device (10) is provided comprising a catheter shaft (1) having an outer surface wall (13), with the shaft enclosing a feeding lumen (14) of substantially circular cross-section and a fluid flow channel (16). A port housing (18) is located at the proximal end of the shaft with the port housing having a main food inlet port (20), a Y-port (23) and a fluid inlet port (25). Near the distal end of the tube are an expandable component member (38) and a food outlet port (30), which port is preferably located at the distal end. The feeding lumen is of a greater diameter than that of the fluid flow channel. The outer surface wall is of a non-circular cross-section. The feeding lumen is of a circular cross-section which permits the passage therethrough of a jejunal tube. The main food inlet port is of a greater diameter than that associated with the Y-port. The method for using this device permits jejunal feeding through a replacement gastrostomy tube without retraumatizing the patient.
