Abstract
Abstract A nasal tube attaching device comprising a body portion having an opening extending axially therethrough. The body is in the configuration of a truncated cone having a tapered end and a substantially triangular end having a configuration substantially conforming to the natural configuration of a human nostril. The tapered end of the body portion extends inwardly of the nostril and the base portion includes a flat surface which is in substantially the same plane as the nostril opening when the device is in position within the nostril. The tapered end is adapted to receive a medical tube which extends inwardly of the patient and which is in communication with the opening extending through the body portion. The area of the base of the body portion is less than that of the area of the nostril opening, thereby providing breathing area through the nostril opening when the device is in position.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
125 words
A nasal feeding device for nesting within the outer opening of a human nostril comprising a body portion generally in the form of a truncated cone having a tapered interior end and an anterior, lobal triangular base contoured in the general shape of a human nostril, said base having a substantially flat surface whereby when said body portiOn is nested within said nostril, said surface is in substantially the same plane as said nostril opening, said body portion having a passageway extending axially therethrough, a medical tube connected to said tapered end and in communication with said passageway, retaining clip means attached to the base of said body and extending outwardly of and gripping said nostril walls when said device is nested within said nostril
Claim 2
Dependent Claim
