  • Patent number: 7770582
    Abstract: A comfortable and viable and removable device of channel-type tongue position correction for anti-snoring. The device is made of wire or band material, including a fixer, an upper and nether force-components which are connected with the fixer. The device is mostly applied on upper jaw. The force end of the upper force-component is designed to be suitable to the soft palate palatine velum, and acts to raise up the soft palate palatine velum and uvula upward/upward and backward suitably. The force end of the nether force-component is designed to be suitable to the normal configuration of the corpora linguae (anterior tongue), and acts on the portion in front of the sensitive position of the hind half of the corpora linguae (anterior tongue) to press the big tongue downward/downward and forward. Thus, depending on the co-action of the upper and nether force-components, the blocked respiratory tract could be expanded to prevent snore and remit sleep apnoea syndrome.
