A device for dispensing a foam medication into a human or animal ear includes a supply of foamable medicine held within a container. The medicine is advanced through a delivery tube that is configured to engage an ear without entering the ear canal to an extent that it contacts the eardrum. The delivery tube has an enlarged end portion that prevents the device from being inserted too far into an ear, and the enlarged end portion has a series of openings oriented in two different directions to deliver foam into the ear forward of the device and around the circumference of the delivery tube. |
