Oral-esophageal-gastric device to diagnose reflux and/or emesis

摘要

A system and method diagnoses esophageal reflux in a patient. A catheter includes a first pressure sensor configured to measure intra-abdominal pressure when the catheter is inserted into the stomach of a patient. A second pressure sensor is located proximal to the distal tip and configured to measure intra-thoracic pressure. A pH indicator is carried by the catheter body and configured to indicate that reflux has occurred in response to an involuntary reflex cough test. A processing device is configured to receive data regarding the first and second pressure sensors and regarding the pH indicator and process that data and assess if reflux is present during the involuntary epoch.

1. A system for diagnosing esophageal reflux in a patient, comprising:
a catheter comprising a first pressure sensor configured to measure intra-abdominal pressure when the catheter is inserted into the stomach of a patient and a second pressure sensor located proximal to the distal tip and configured to measure intra-thoracic pressure and a pH indicator carried by the catheter body and configured to indicate that reflux has occurred in response to an involuntary reflex cough event; a nebulizer containing an agent that induces the involuntary cough event within the patient; at least one electromyogram (EMG) pad configured to be attached to the lumbar region of the patient's back and obtain an EMG from involuntary cough activated paraspinal muscles; and a processing device configured to receive data regarding the first and second pressure sensors and the pH indicator and the EMG pad and process said data and assess if reflux is present during the involuntary event.
