Abstract: An ear irrigation device for flushing an ear canal to remove debris safely and without the risk of over-insertion. The ear irrigation device includes a disk that has a top and a bottom. A conical protrusion extends from a central top portion of the disc. A tubular member extends from a central bottom portion of the disc. The tubular member has a lure lock to connect with the irrigation fluid delivery system. A bore extends through the conical protrusion, the disc, and opens into the tubular member, wherein the bore forms a channel through which a stream of water can pass through and eject from the tip of the conical protrusion. The conical protrusion can insert into an orifice while the disc prevents over-insertion. Multiple drain holes provided in the conical protrusion can channel out the irrigation fluid flushed from the ear canal.
