There are numerous devices and aids available for preventing snoring. Most of them are cumbersome and inconvenient to use. My invention offers a simple and easy-to-use way to reduce or prevent snoring. The cause of snoring is quite simple: we simply don't get enough air through our noses. When we breathe, the suction in the nose increases, pulling the nostrils inwards. In extreme cases, breathing then takes over the mouth. However, since the soft palate and uvula relax during sleep, this airway is also constricted, resulting in snoring sounds. In extreme cases, breathing stops completely, leading to sleep apnea. It is therefore essential to ensure an adequate supply of air from the outset. This, in turn, means that the nostrils must remain unobstructed. With this invention, the nostrils remain unobstructed and an adequate supply of air is guaranteed. The nasal sleeves are inserted into both nostrils. The textured surface (knurling) ensures the necessary grip of the nasal sleeves in the nostrils.

Soft palate cryoprobes and associated methods and systems for treating obstructive sleep apnea are disclosed herein. A system can include a thermal treatment unit, a conduit system fluidically coupled to the thermal treatment unit, an insulator having an insulating pad, and a soft palate cryoprobe having an inlet tube and an outlet tube, each fluidically coupled to the conduit system. The soft palate cryoprobe can further include an elongated housing removably coupled to an applicator having a distal face. In operation, the distal face of the applicator is in thermal contact with the soft palate, while the insulating pad provides thermal insulation to the posterior pharyngeal wall. A controller can be operably coupled to the thermal treatment unit and configured to direct temperature-controlled fluid to the inlet tube in response to sensor readings.

This invention provides a device for treating snoring, comprising a support segment with a connecting segment at its tail end. The support segment is composed of multiple elastic keels, each connected at its tail end to the connecting segment. Each elastic keel expands outwards when the support segment is extended. It also includes an insertion tube, which is hollow and allows the support segment to retract and be placed within it. The support segment, which can be inserted into the pharynx for further expansion, opens the airway and prevents snoring caused by soft palate or pharyngeal collapse. After the support segment is delivered to its position via the insertion device, the device is dislodged, allowing the support segment to expand and support the soft palate or posterior tongue root. Alternatively, it can be delivered to a designated location via a delivery tube, and by pulling the inner core outwards, the elastic keels of the support segment bend and expand to support the soft palate or posterior tongue root, thus opening the airway and treating snoring. This method does not require removal of the soft palate and therefore does not affect the patient's eating.
