ABSTRACT:
The invention provides an ear irrigation device for injecting a fluid into an external ear canal extending between an external ear and a tympanic membrane. The external ear canal includes an outer portion extending inwardly from the external ear and including cerumen-producing glands and an inner portion between the tympanic membrane and the outer portion. The ear irrigation device has a longitudinally extending body including an inward end and an outward end. Also, the ear irrigation device includes an input duct extending from the outward end to the inward end and terminating in a nozzle. The nozzle is adapted to direct fluid out of the body both transversely and towards the external ear when the inward end is positioned proximate to the inner portion of the external ear canal.
