Abstract: A liquid dispensing tip comprises both an alternative dispensing tip and an adapter. The alternative tip is sized to be screwed directly onto dispensing bottles having a large diameter connector. The adapter insert is placed inside the alternative dispensing tip when the dispensing bottle has a small diameter connector.

Abstract: An attachment for use with a unit dose eye drop dispenser comprises a tapered receptacle and a lateral positioning arm. The tapered receptacle is “squeezable” so that a reservoir of the unit dose dispenser can be placed within the receptacle and the walls of the receptacle squeezed to dispense a droplet. The positioning arm is shaped to be placed over the patient's nosebridge to properly position the receptacle over the eye for optimum placement of an eye drop.

Abstract: A drop metering device for use in combination with an eye dropper or other liquid dispenser comprises a rigid receptacle having an open chamber for removably receiving a squeeze bottle of the dropper. The plunger is mounted to reciprocate radially inwardly with respect to the rigid receptacle so that, when the squeeze bottle is in place, a controlled deflection can be induced in the squeeze bottle. The plunger may be mounted on a lever arm with a ring adjustment mechanism which provides a variable stop surface between the lever arm and the receptacle. Alternatively, the plunger may be mounted in a radially oriented slide bearing with a threadably mounted stop member for adjusting the length of travel.

Abstract: Apparatus for attaching to a squeeze bottle or other dispenser for delivering drops to an eye comprises an axial member and a laterally extending leg. The axial member is attached to the bottle and receives drops or liquid therefrom. The leg is rested against the patient's nose bridge so that it directs fluid to a trough and releases drops into the eye after a predetermined threshold volume is exceeded.
