摘要：
A nasal insert may include a wall in the shape of a tube, the wall including a first end defining a first orifice and a second end defining a second orifice. The first end may have a diameter, diagonal measurement, or cross-sectional area larger than that of the second end. The first end may define at least one break in the wall, so that the first end incompletely encircles the first orifice. The second end may completely encircle the second orifice.
