Abstract: An irrigation device for injecting a fluid into a channel formed in an object relative to a surface of the object for washing walls defining the channel. The walls intersect to form at least one terminal portion disposed distal to the surface. The irrigation device includes an elongate body extending between an inward end and an outward end. The body includes a nozzle positioned at the inward end, and an input duct extending between the outward end and the inward end and in fluid communication with the nozzle for directing the fluid to the nozzle. The nozzle includes a plurality of output ducts in fluid communication with the input duct. The output ducts are positioned to direct the fluid out of the body substantially toward the walls and substantially toward the surface upon positioning the nozzle proximal to the terminal portion of the channel.

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.
