Abstract
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.
Claims29
A naso/orogastric device having backflow blocking means, comprising:
- 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 said naso/orogastric tube, having a pressure dependent volume;
- at least one esophageal sensor that detects fluid around at least one segment of said naso/orogastric tube;
- and
- a pressure regulator that regulates a pressure within said at least one elastic esophageal body according to said detection;
- and
- wherein said at least one esophageal sensor comprises at least one impedance sensor for sensing an impedance change around at least one segment of said naso/orogastric tube.
(canceled)
A method of preventing reflux during at least one of tube feeding and esophageal endoscopy of patient, comprising:
- disposing a naso/orogastric tube having at least one elastic esophageal body within the esophagus so that at least a distal end thereof being placed in the stomach lumen of a patient and said at least one elastic esophageal body being placed along a segment of esophagus;
- detecting fluid in at least one region along esophagus in at least position around said naso/orogastric tube, between said segment and the stomach;
- and
- regulating a pressure within said at least one elastic esophageal body according to said detection.
A naso/orogastric device having backflow blocking means, comprising:
- a naso/orogastric tube having a lumen for delivering content into the stomach lumen of a patient;
- at least one backflow blocking means positioned along said naso/orogastric tube and a having at least one of a perimeter wider than the perimeter of said naso/orogastric tube and an adjustable structure having at least one state wider than the perimeter of said naso/orogastric tube;
- and
- an elastic stomach body at a distal end of said naso/orogastric tube and configured for being inflated by said content so as to have a perimeter wider than the perimeter of the lower esophageal sphincter of said patient.
A naso/orogastric device, comprising:
- 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 positioning sensor mounted along said naso/orogastric tube to measure impedance around at least one segment of said naso/orogastric tube;
- and
- a controller which monitors changes in the positioning of said naso/orogastric tube according to said impedance.
