589600 An apparatus for alleviating obstruction of an airway, comprising a therapy appliance 101 comprising a peripheral surface configured to mate with and thereby enclose an external area of the throat overlying the upper respiratory passage, where when mated, the therapy appliance 101 provides a space-filled chamber 102 lying between the inner surface of the therapy appliance 101 and the throat having an enclosed volume of between 0.5 and 12 in3 , wherein the peripheral edge is configured to provide a pressure along the contact surface with the user's skin of 60 mm Hg or less at a partial vacuum level within the enclosed volume of between about 7.6 cm to about 61 cm of water, an air pump operably connected to the chamber 102 and configured to maintain a partial vacuum within the chamber 102, and a vacuum control module comprising a microcontroller operatively coupled to a vacuum or pressure sensor and motor control circuitry which controls the pump on/off cycles and/or speed. |
