Method and device of detecting and/or blocking reflux

摘要

A naso/orogastric device having backflow blocking means and comprises a naso/orogastric tube sized and shaped for being disposed within the esophagus so that at least a distal end thereof being placed in the stomach lumen of a patient, at least one elastic esophageal body, positioned along the naso/orogastric tube, having a pressure dependent volume, at least one esophageal sensor that detects fluid around at least one segment of the naso/orogastric tube, and a pressure regulator that regulates a pressure within the elastic esophageal body according to the detection.

1. A naso/orogastric device having backflow blocking means and adapted to feed a patient, comprising:
a naso/orogastric tube having a distal end and a feeding channel with at least one feeding opening located in said distal end for conducting a feeding content and first and second recesses formed along at least one segment of a lateral surface of said naso/orogastric tube, said naso/orogastric tube is sized and shaped for being disposed within the esophagus so that at least a distal end thereof is in the stomach lumen of a patient while said at least one segment being placed in the esophagus of said patient; at least one elastic esophageal body, positioned above said first and sec recesses along said naso/orogastric tube, having a pressure dependent volume; at least one impedance sensor located in said first and second recesses for sensing an impedance while said feeding channel is used for feeding said patient via said at least one feeding opening, said first recess is formed above said second recess, said first recess and said second recess are formed above said at least one feeding opening; and a pressure regulator that regulates a pressure within said at least one elastic esophageal body according to said impedance.
