Abstract:
A method for clearing an obstruction in an eustachian tube opening in the nasopharynx region of a human throat behind which a volume of fluid has accumulated within a eustachian tube, such as during an infection of the middle ear, comprising the steps of:vibrating the nasopharynx region in the area of the eustachian tube opening to at least one of break up and dislodge the obstruction without permanent damage to the eustachian tube opening; and removing the fluid within the eustachian tube accumulated behind the obstruction through the eustachian tube opening in association with the vibrating step; wherein the vibrating step and the removing step are performed by a device comprising a housing having a longitudinal internal conduit, the internal conduit terminating at a first end and a second end, the first and second ends having attachment portions thereon, the attachment portion at the first end being adapted to be interconnected to a suction source; a motor mechanically interconnected to the second end attachment portion and adapted to impart vibratory movement to the second end attachment portion; an elongated tip having a first end and a second end, each of the first and second ends having an opening therein, the tip having a longitudinal internal conduit extending between the openings in the first and second ends of the tip, the first end of the tip being mounted to the attachment portion at the housing second end wherein the internal conduit of the tip is in fluid communication with the longitudinal conduit of the housing; whereby actuation of the motor imparts vibratory movement to the second end attachment portion, and thereby to the attached tip and, when the housing first attachment portion is interconnected to a suction source, suction and vibration are simultaneously applied to the tip second end and, thus, when the tip second end is applied against an obstructed body cavity opening, the vibration acts to break up the obstruction and the suction contemporaneously acts to withdraw the accumulated fluid from the eustachian tube opening; whereby, once the vibrating step has reduced the obstruction in the eustachian tube opening, the removing step withdraws the fluid from within the eustachian tube to relieve pain and discomfort associated with the fluid accumulation.
