Research Abstract

We have developed an optical guide system which prevents incorrect insertion of a nasogastric feeding catheter into the trachea. Near-infrared light laser diode was connected to a plastic optical fiber, which tip was fabricated to scatter light laterally and the fiber was fit into the catheter. The catheter was inserted into the stomach and transmitted light through the abdominal wall was successfully observed with a cooled CCD camera. This optical guide system has a potential for safe insertion of a nasogastric feeding catheter.
