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.
