Nasal inserts

摘要

Devices for nasal insertion may include an open-ended tubular element which extends along a central tube axis between a first end and a second end, the first end being larger than the second end, and in which the tubular element includes at least one spiral strut extending from the first end to the second end, and/or a nodule having an internal face, a rounded external face, and a stalk extending from the internal face and terminating in an anchor sufficiently larger than a receptacle in the tubular element and sufficiently deformable as to be pressed through the receptacle to affix the nodule to the tubular element.

主权项

1. A device for nasal insertion comprising an open-ended tubular element having:
a bottom ring; a top ring, the top ring being a closed ring; and at least one spiral strut connected to the bottom ring and to the top ring, the at least one spiral strut consisting of a partial spiral; wherein the tubular element extends along a central tube axis between the bottom ring and the top ring, the bottom ring having a larger diameter than the top ring; wherein the at least one spiral strut extends in the shape of a conic helix having a continuously decreasing radius from a central axis of the device from the bottom ring to the top ring, and wherein the nasal device is configured for insertion into a nasal passage to increase airflow therethrough.
