Esophageal pressure monitoring device

摘要

A device for monitoring esophageal pressure in patients comprises a nasogastric tube provided with an esophageal balloon cuff communicating through wallports with a secondary lumen that leads to an external connector tube through which continuous measurements of esophageal pressure can be made without interruption of the function of the nasogastric tube. The tube may include a tertiary lumen that serves to vent the major tube lumen at the distal end to prevent excessive vacuum from developing when suction is applied to the tube.
