The study and the development of an optical fiber sensor for entero-gastric and non-acid gastro-esophageal reflux is described. The working principle, based on the spectrophotometric properties of the bile, which constitutes the main part of the reflux, differs from the traditional measurement method, based on pH monitoring. The measuring apparatus is described as well as experimental "in vitro" and preliminary "in vivo" tests are reported.

A fiber optic system for the detection of enterogastric reflux

1989

Abstract

The study and the development of an optical fiber sensor for entero-gastric and non-acid gastro-esophageal reflux is described. The working principle, based on the spectrophotometric properties of the bile, which constitutes the main part of the reflux, differs from the traditional measurement method, based on pH monitoring. The measuring apparatus is described as well as experimental "in vitro" and preliminary "in vivo" tests are reported.
