Noson Nasal Dilator - Made in Switzerland

My wife Kathy is expecting our third son any day now, and her experiences during her current and past pregnancies bring up some important issues that all men and women, pregnant or not, should know about. Since the soft foam pads 12 take a permanent set after several months, the contact units 11 should be replaced every 15-30 days with the new units merely by pulling the pads off the contact portions 3, and the new units are forced onto contact-portions 3 which are inserted into the pocket formed by the film 13. The nasal strips should be replaced daily for good hygiene.
By contrast, because in the present invention the spring-force is independent of the stick-force, the adhesive-area on the skin and the stick-force can inherently be much smaller than for all external dilators, since the adhesive only must keep the dilator from falling out, as discussed.

30. A nasal dilator defined in claim 29: and said UV-spring comprising substantially flat spring material prebent into a UV-shape in its free position; and centering means comprising, an aperture at the center of said nasal strip, and projecting means at the center of said UV-spring disposed to enter said aperture, for enabling the wearer to readily align said center of said nasal strip with said center of said UV-spring when installing each new nasal strip.
To install the dilator of the present invention, the contact-portions 3 of the UV-spring 1 are inserted into the two nostrils so the lower ends of the contact-portions with pads 3 a are just visible, or if more comfortable, install just above or near the nasal flange area.
18. A Noson as defined in claim 6; and pad means having a soft resilient material with a smooth surface and rounded edges connected to each of said leg portions at to provide the only contact of said UV-spring with said inner surface of said nostril-walls to avoid discomfort for the wearer; and said flexible strip including a semi-rigid but flexible non-adhesive piece attached to said nasal strip between said two end adhesive segments, for enabling the wearer to install said UV-spring in said nasal openings without the wearer's fingers contacting said adhesive segments and to position a large share of said end adhesive segments for adhering to said outer surfaces above the nose-flange.

6. A nasal dilator comprising in combination; a UV-spring having a central portion and two leg-portions including contact portions at the ends thereof for insertion in the nasal opening formed by the nostril walls and acting on the inner surfaces thereof for increasing said nasal opening to improve the breathing of the wearer; retaining means comprising a flexible nasal strip connected to said UV-spring at the central portion thereof and extending along both of said leg-portions; and said strip including two end adhesive segments, adapted to be pressed onto the outer surfaces of said nostril walls by the wearer to prevent said UV-spring from falling out of said nasal opening.
3. A nasal dilator comprising in combination: spreading means having a portion for insertion in the nasal opening to act on at least one nostril wall of the wearer for increasing said nasal opening to improve the breathing of the wearer; and retaining means including a flexible strip operatively connected to said spreading means and having adhesive means adapted to be pressed onto the outer nasal surface by the wearer, for preventing said dilator from falling out of said nasal opening.

In the review, they were divided into four categories: external nasal dilators worn over the bridge of the nose; internal nasal stents placed into each nostril; clips positioned over the nasal septum; and septal stimulators that apply pressure to the nasal septum to increase circulation in the area and help open nasal passages.
Overnight polysomnography was performed in the sleep laboratory (EMBLA; Flagra hf. Medical Devices, Reykjavik, Iceland) and included electroencephalography, electrooculography, electromyography, oximetry, measurements of airflow (oronasal thermistor and pressure cannula), and measurements of the rib cage and abdominal movements during breathing.

One external dilator improved my breathing from 60% of normal to only about 70%, and the strong adhesive force irratated my skin which became red after only a few days of use; these characteristics are inherent in all external dilators, to be discussed.
