Crazy Straw Eyedropper

The task of heating eyedrops is on everyone's mind these days. One must really keep their eyes open for these trends.

The crazy straw eyedropper heats eyedrops up to the required 105F required to liquify meibomian secretions using friction alone. The idea is to implement a meandering accordion-style channel leading to the orifice of the eyedropper. As pressure is applied, the liquid flows through this channel and heats up via frictional forces. The mechanism will be adjusted to impart a sufficient amount of heat from an ambient starting temperature. A temperature-sensitive dye will be embedded in the final stage of the channel to confirm the proper temperature has been reached. If the user finds the temperature is not suitable, they can twist and loop the channel around all sorts of ways to impart further frictional heating from bends and elongation. Perhaps there will be little ribs and microstructures on the inner surface to amplify heating.
