Abstract:
A nasal dilator for preventing outer wall tissue of nasal passages of a human nose from drawing in during breathing, comprising:a unitary body including a single flexible pad having a surface area and peripheral edge, the unitary body having a pair of spaced apart end surfaces and a portion having an area of joinder between the spaced apart end surfaces, at least one spring member having opposite flat surfaces, the flexible pad being for engaging the at least one spring member secured thereto adjacent to at least each end surface, the unitary body being of non-uniform thickness and having a first thickness and a portion of greater thickness in an area of the flexible pad adjacent to the spring member, the unitary body being in a substantially planar state absent external forces applied thereto, such that the pair of spaced apart end surfaces which, if forced toward one another from initial positions within a plane of said unitary body to substantially reduce a direct spacing therebetween by a spacing reduction force external to said unitary body results in restoring forces in said unitary body tending to restore said direct spacing between said end surfaces, each of the end surfaces in area being at least about twice the area of the joinder portion between the end surfaces;first adhesive means for securing the spring member at each end surface to the flexible pad such that one of the flat surfaces of the spring member adheres with the flexible pad at each end surface; andsecond adhesive means with said end surfaces of the flexible pad capable of engaging surfaces of nasal outer wall tissues sufficiently to remain so engaged against said restoring forces, such that the restoring forces in said unitary body tend to restore the unitary body to the substantially planar state and dilate a human's nose by urging outer wall tissues of such a human's nose outwardly with the end surfaces of said spring member, and also on release of the end surfaces from engagement with the outer wall tissue of such a human's nose the restoring forces further urging the unitary body to return to the substantially planar state, and the arrangement consisting of the flexible pad and spring member at the respective end surfaces for engaging nasal outer wall surfaces, and the adhesive means for adhering the unitary body to the outer wall tissues of a human's nose.
