US Patent:

56906200, Nov 25, 1997

Filed:

Aug 19, 1996

Appl. No.:

8/697104

Inventors:

Michael McFarland Knott - Tahoe City CA

International Classification:

A61M 2500

US Classification:

604280

Abstract:

A nasogastric (NG) tube provided with a normally-curved or normally-bent leading end. When passed, the normally-curved/bent leading end negotiates the nasopharynx with the tip of the NG tube biased to conform to the shape of the soft palate, thereby applying a reduced pressure against the posterior nasopharynx. After passing the nasopharynx, the normally-curved/bent leading end is rotated 180. degree. such that the tip is biased in a posterior direction such that it more reliably enters the esophagus. After entering the esophagus, the NG tube is rotated an additional 90. degree. such that when the tip of the NG tube enters the stomach, the tip is biased toward the stomach outlet. A second curved portion located near the normally-curved/bent leading end provides additional biasing force to help the tip enter the esophagus. A longitudinal line, stripe or other form of marking is placed on the tube to prompt the nurse/physician when to make the 180. degree. and 90. degree. rotations.

US Classification:

Abstract:

This invention relates to external, non-invasive compression devices to treat anterior nosebleeds and a method for using those external compression devices to treat anterior nosebleeds without the insertion of any material or device into the nasal cavity. This patent concerns a method for automatically applying external pressure to the nose to stop nosebleeds, describes how a new use can be made of an existing device to implement the method, and also describes a preferable anatomically conforming device which better fits the shape of the nose and thus can be more comfortable and effective.
