A nasogastric (NG) tube for placement into the lumen of the stomach by way of a nostril having a tapered tip, a lubricious coating, and one or more expandable balloons that surround drainage ports. During insertion into the stomach the tapered tip and lubricious coating facilitate the tube traversing the patient's nasopharynx and esophagus with reduced injury. During insertion the expandable balloons are maintained in a low profile state but upon reaching the stomach lumen are expanded to a high profile state and improve drainage by pushing the stomach wall away from the drainage ports. |
