Abstract
An apparatus is provided for relaxing an apneic obstruction in a nasopharyngeal airway of a patient. A bolus chamber and a rearward chamber are defined within a housing. A movable piston within the housing is actuated using a pair of magnets. When an impeller, mounted within the rearward chamber, rotates as a result of patient exhalation into the rearward chamber, the repulsive force between said magnets causes said piston to move and drive a bolus of air into the airway of the patient.
