Nasal Dilator In Cases Of Nasal Obstruction
Sleep apnea is a sleep disorder characterized by a pause in breathing. Similarly, many people with sleep-breathing problems already sleep on their sides or stomachs already for the following reasons: Due to various degrees of jaw narrowing, the tongue and voice box (which grow to their normal size), takes up too much space inside the mouth.
Metabolic gas analysis was not performed in this study because the more practical comparison we were seeking (LT) did not require this measurement and because we lacked the specific mask that would allow for oronasal breathing during the oxygen consumption test.
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.
5. A unblocking the nasal airway comprising in combination: a UV-shaped spring having a central portion and two leg-portions for insertion in the nasal opening and acting on the two nostril walls for increasing said nasal opening to improve the breathing of the wearer; and retaining means including a flexible member connected to said UV-shaped spring at a central portion thereof and extending along both of said leg-portions and having adhesive means adapted to be pressed onto the outer nasal surface by the wearer to prevent said dilator from falling out of said nasal opening.
38. A nasal dilator as defined in claim 31: and said non-adhesive segment comprising a single thin semi-rigid but flexible non-adhesive piece attached along its entire length to said flexible strip between said two end adhesive segments and extending equal distances from said connection of said strip with said UV-spring at the central portion thereof; and connecting means operatively associated with said non-adhesive piece for securing said non-adhesive piece to said central portion of said spring, for enabling the wearer to install said leg-portions of said UV-spring in said nasal opening without the wearer's fingers contacting said adhesive segments and to maintain alignment of said strip with said spring as a result of the transverse rigidity of said semi-rigid piece.
Participants who met the entrance criteria, who were currently suffering from nasal congestion every night or almost every night, reported trouble with their sleep and had baseline nasal openness scores at bedtime during the qualification phase of ≤ 70 on a 100-point VAS on at least four of seven qualification nights were randomized to one of two treatments for use at home.
In the subset of subjects at risk for sleep apnea, both active strips produced significantly (P < 0.05) greater improvements from baseline versus placebo on all three composite PIRS variables on day 7. At day 14, both active strips showed improvements in quality of life versus the placebo strip in the subgroup at risk for sleep apnea, and the butterfly prototype was also significantly better than placebo with regard to daytime distress (see Additional file 1 : Table S1).
33. A nasal dilator as defined in claim 31; and said non-adhesive segment comprising at least one thin semi-rigid piece attached to said nasal strip between said two end-adhesive segments, to determine the portion of the outer nostril walls subjected to said end-adhesive segments.
Abstract: A method for non-surgically treating an internal nasal valve of a patient comprising, injecting a working device into the internal nasal valve of the patient, wherein the injected working device in the nasal tissue causes an alteration of an internal or external nasal valve.
Abstract: Methods and apparatus for treating disorders of the ear, nose, throat or paranasal sinuses, including methods and apparatus for dilating ostia, passageways and other anatomical structures, endoscopic methods and apparatus for endoscopic visualization of structures within the ear, nose, throat or paranasal sinuses, navigation devices for use in conjunction with image guidance or navigation system and hand held devices having pistol type grips and other handpieces.
The subject answered questions about the dry mouth feeling on a 1-5-scale (5 the driest) and answered a validated questionnaire about quality of sleep (Epworth Sleepiness Scale 53 ). These three instruments were administered immediately before and 2 weeks after the study started.
It is likely that, among patients with moderate to severe OSA, neither the site of obstruction during apnea nor the site of generation during snoring is in the nose, and rather this location may be in the oropharynx or hypopharynx at the level of the soft palate or the velopharyngeal level (22).
