Optimized Nasal Breathing

It is usually amusing to hear a person snore. Abstract: The present invention provides a nasal dilator including: two intranasal stents (1) and a connecting band (2), wherein each of two ends of the connecting band (2) being symmetrically connected to one intranasal stent (1), each intranasal stent (1) having an elastic band-shape structure, each intranasal stent (1) has a straight-line shape, an arc-line shape, a bow shape, or a fold-line shape in a cross section perpendicular to a width direction of the elastic banded structure, each intranasal stent (1), along a length direction of the elastic band-shape structure, comprises: a nasal septum supporting section (3), a bending section (4), and a nasal alar dilating section (5), each intranasal stent (1) has a generally C-shape in a cross-section perpendicular to a central axis of nasal passages, wherein an opening of the C-shape faces towards a nasal base (11).
The butterfly and BRNS strips showed significant (P < 0.05) improvement versus placebo on PIRS satisfaction with sleep at day 7 least square (LS) mean changes: − 0.7, − 0.6, and − 0.2, respectively, and the butterfly strip also showed significant improvement from baseline on this outcome versus placebo at day 14 (− 1.0 vs − 0.5). On the NRQLQ, both the butterfly prototype and BRNS clear were more effective than placebo in improving symptoms on waking at day 7 (LS mean changes: − 7.9, − 7.2, and − 4.1, respectively); the BRNS clear was significantly more effective than placebo in improving sleep problems at day 7 (− 7.4 vs − 4.2). There were no between-treatment differences on the CQ7.

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.
Participants who met the entrance criteria, were currently suffering from nasal congestion, reported trouble with their sleep and had baseline nasal openness scores at bedtime during Noson the qualification phase of ≤ 70 on a 100-point Visual Analogue Scale (VAS) on at least four of seven qualification nights were randomized to one of two treatments for use at home.

In the subgroup with AHI 0-5, the nasal dilator was associated with a reduction in the number of spontaneous arousals during the night, which decreased from a mean (SD) of 7.74 (4.11) at baseline to 5.81 (3.74) at night 8 and 6.15 (4.16) at night 29 of the active phase (P value not determined) and from 10.50 (7.22) on the night without the strip to 8.37 (6.47) on the night with the strip in the nasal resistance phase (P = 0.0235).
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.

Based on the findings of a single study ( 12 ), it has been suggested that nasal strips can help an athlete do the same amount of exercise using less energy” ( 8 ). The rationale is that if airway resistance is reduced, then respiration is easier; thus, the metabolic cost of ventilation is lower.
The inclusion criteria were as follows: (1) patients: adults ≥18 years old who have OSA, (2) intervention: nasal dilators, (3) comparison: sleep study data pretreatment and treatment, (4) outcome: sleep study parameters including apnea-hypopnea index (AHI), apnea index (AI), oxygen saturations, and sleepiness, and (5) study designs: all designs and all languages.

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).
