Nasal dilation device

Abstract

A nasal dilation device comprises a pair of dilating frames for insertion into respective nasal passages. An external abutment member is joined between the pair of dilating frames to abut an external nasal valve. Each dilating frame comprises a frame member wound in a generally helical pattern about a longitudinal axis of the dilating frame to form a plurality of windings spaced from one another in a direction of the longitudinal axis. By providing a frame formed of a helical member, a resulting open frame design of a dilating frame is provided which is easy to manufacture, of simple structure, with substantially no protruding ends or edges so that the device can be easily and safely inserted into a nasal passage without tearing or causing harm to the soft internal tissues thereof. Outward dilating pressure applied to the internal nasal passage is also distributed over a larger area for comfort.

Description

[0001] This application benefits from US Provisional Application No. 60 / 866.079, filed November 16, 2006. technical field [0002] The present invention relates to a device for insertion into a person's nasal passage for dilating the nasal passage to allow the person to breathe more easily. Background technique [0003] Improving a person's ability to breathe is important, for example, when it is desired to increase breathing while exercising, to reduce snoring, or for general health. It is known that many people are restricted from breathing due to narrow nasal passages, so that improved breathing can be achieved by dilating or otherwise increasing the internal size of a person's nasal passages. [0004] Various attempts to improve respiration have been made, as disclosed in the following US patents: 4,759,365 to Askinazy; 6,978,781 to Jordan; 6,270,512 to Rittmann; 6,004,342 to Filis; 3,710,799 to Caballero; 1,672,591 belonging to Wells; 1,256,188 belonging to Wilson; and...

AI Technical Summary

Problems solved by technology

[0005] Prior art designs of nasal dilation devices are often cumbersome, such that the device itself partially restricts the passage of air through the nasal passages

While some designs do have open frames, generally known open frame designs either include edges that may catch on sensitive internal tissue within the nasal passage during insertion or removal, are difficult to manufacture due to their complex construction, or The device does not include a sufficient number of frame members in the open frame design to evenly balance the outward pressure used to dilate the nasal passage against the soft inner tissues of the nasal cavity
