ABSTRACT:
A dropper 10 is provided which allows a person to precisely instill eye drop solution while the person's head and the dropper 10 are oriented in an upright position. The dropper 10 includes a deformable, resilient reservoir 40 of medicinal fluid which may be squeezed to to cause the fluid to flow up a supply conduit 15 to a housing 20 of the dropper 10. The fluid then flows out an opening 32 in a tip 31 of the dropper 10. An inner rod 130 or inner delivery tube 30 extends along an interior of the supply conduit 15. The tube 30 or rod 130 discourages air bubbles from being entrapped within the conduit 15. The tip 31 extends forward from a center line 41 along an extension 27 which is substantially perpendicular to a collar 50 extending up from the reservoir 40.
