Abstract

A low profile adaptor is disclosed for use with a gastrostomy feeding tube which has been inserted by means of conventional endoscopic procedures or with a replacement feeding tube inserted through the patient's stomach. The tube is cut to the approximate length by the surgeon. The adaptor comprises an anti-reflux valve assembly having a stem which can be plugged into the open end of the feeding tube. The valve assembly contains a seal which functions as a one-way valve to prevent reflux of gastric contents but which permits the introduction of feeding solution into the feeding tube. A clamp is placed around the feeding tube and the valve stem and locked into place to secure the valve assembly to the feeding tube at a location flush with the patient's skin. A silicone cover is placed around the clamp to protect the patient from skin irritation caused by the clamp, and also to protect the clamp and valve assembly from contamination.
