Title
(EN) METHODS AND APPARATUS FOR ACCESSING AND MONITORING THE GASTROINTESTINAL TRACT
(FR) PROCÉDÉS ET APPAREIL D'ACCÈS ET DE SURVEILLANCE DU TRACTUS GASTRO-INTESTINAL
Abstract
(EN)
Methods and apparatus for accessing and monitoring the gastrointestinal tract are described herein. One variation of a feeding tube system may generally comprise a gastric access device having a length, a controller in communication with the gastric access device, and one or more impedance or conductivity sensors positioned along the length and one or more temperature sensors positioned along the length. The controller may be configured to receive a first signal associated with the impedance or conductivity sensors and a second signal associated with respiration and determine whether a placement of the gastric access device is within a stomach of the subject.

La présente invention concerne des procédés et un appareil d'accès au tractus gastro-intestinal et de surveillance de celui-ci. Une variante d'un système de tube d'alimentation peut généralement comprendre un dispositif d'accès gastrique ayant une longueur, un dispositif de commande en communication avec le dispositif d'accès gastrique et un ou plusieurs capteurs d'impédance ou de conductivité positionnés le long de la longueur et un ou plusieurs capteurs de température positionnés le long de la longueur. Le dispositif de commande peut être configuré pour recevoir un premier signal associé aux capteurs d'impédance ou de conductivité et un second signal associé à la respiration et déterminer si un placement du dispositif d'accès gastrique est à l'intérieur d'un estomac du sujet.
