Device to block emesis and reflux and associated system and method

摘要

A nasogastric/orogastric (Ng/Og) device includes a main lumen configured for at least one of gastric decompression, enteral feeding and enteral medication administration. An expandable esophageal cuff is carried by the device body and configured in a normally expanded position such that when inserted within the esophagus, the esophageal cuff conforms to the interior surface of the esophagus and emesis and/or reflux is blocked from passing out of the stomach and past the esophageal cuff. A vacuum lumen is carried by the device body and connected to the expandable esophageal cuff. When vacuum is applied, the esophageal cuff is contracted against the device body to permit the device to be inserted and placed within the esophagus. When the vacuum is released, the esophageal cuff expands against the interior surface of the esophagus.

主权项

1. A system of diagnosing a patient for a physiological abnormality while protecting their airway, comprising:
a nasogastric/orogastric (Ng/Og) device, comprising:
an elongate device body having a distal end for insertion into the stomach through the esophagus and a proximal end, and having a main lumen extending the length of the body and configured for at least one of gastric decompression, enteral feeding and enteral medication administration;an expandable esophageal cuff carried by the device body mid-esophagus and configured in a normally expanded position such that when inserted within the esophagus the esophageal cuff conforms to the interior surface of the esophagus and emesis and/or reflux is blocked from passing out of the stomach and past the esophageal cuff; anda vacuum lumen carried by the device body and connected to the expandable esophageal cuff, wherein when vacuum is applied, the esophageal cuff is contracted against the device body to permit the device to be inserted and placed within the esophagus, and when the vacuum is released, the esophageal cuff expands against the interior surface of the esophagus; a port through which medication is delivered for administrating an involuntary reflex cough test; at least one electromyogram (EMG) pad configured to be attached to the lumbar region of a patient's back and obtain an EMG from involuntary cough activated paraspinal muscles; and a processing device configured to receive the EMG and process same to determine a physiological abnormality.
