ABSTRACT:
A system for ear irrigation, consisting of an applicator for applying a solution of water at a temperature of 100.degree. F. to 105.degree. F., and at a pressure pulsating between 0 and 75 psi, at a frequency substantially above 100 cycles per minute--preferably 1,000 cycles per minute or somewhat higher.
The flow of liquid is supplied to the ear by means of an applicator having a tapered end, which ends in a smooth convex manner. The tube connects by a male connector to a standard female counterpart, using a pulsating dental irrigation device. The distal end inserts into the ear, and has a smooth convex ending. At the distal end, three holes are present with accompanying three grooves. The position of the three openings provides for a pulsating solution to eject through two holes on one side and one hole on the opposite side. Thus, the solution rocks the cerumen, pulses the cerumen, and washes it. Yet, it does not strike or injure the eardrum.
Rocking the cerumen, as well as pulsing it, serves to enhance easy removal of the cerumen. This is in addition to the regular washing that the water performs.
Because the openings on the right and left offset each other as the fluid ejects, the distal end of the irrigator vibrates little. At the proximal end, the irrigator tip has three elevations which correspond to the three openings. Thus, the operator can identify the circular position of the three openings without viewing them by observing the three elevations. The tip is provided with a finger grip for grasping and holding the tip effectively. This type of connector allows for swiveling or rotating the ear irrigator tip.
Three channels are cut into the distal end to allow easy access of water and to prevent build-up of water pressure.
