Described herein are nasal respiratory devices and methods for treating a variety of medical diseases including snoring and sleep apnea through the use of such devices. In general, theses devices include an airflow resistor (4), such as a flap valve (32) and a holdfast (5) for securing the device in communication with the subject's nasal cavity (16). The devices may be configured to include leak paths to regulate the expiratory pressure when worn by a subject. Methods for using these devices may include securing a device over or at least partially within (or both of) a subject's nasal cavities.

La présente invention concerne des dispositifs de respiration nasale et des procédés permettant de traiter diverses affections médicales et notamment la rhoncopathie et l'apnée du sommeil au moyen de tels dispositifs. En général, ces dispositifs comprennent un frein à l'écoulement de l'air tel qu'une soupape à clapet, et une fixation pour maintenir le dispositif en communication avec la cavité nasale du sujet. Ces dispositifs peuvent être conçus pour comporter des chemins de fuite permettant de réguler la pression d'expiration quand ces dispositifs sont portés par un sujet. Les procédés d'utilisation de ces dispositifs peuvent impliquer leur fixation au-dessus ou au moins partiellement à l'intérieur, (ou aussi bien au-dessus que partiellement à l'intérieur) des cavités nasales du sujet.
