Liquid dispensing reservoir

A liquid dispensing device for dispensing a precise quantity of a liquid into an ophthalmic environment of an individual, the liquid dispensing device comprising:

• a self-collapsible medical grade liquid reservoir comprising a rigid base portion attached and sealed to a highly sensitive flexible foil lid portion having a thickness in the range of 0.03 millimeters to 0.4 millimeters, to form a sealed cavity between the rigid base and the flexible foil lid,
• wherein the attachment of the rigid base portion to the highly sensitive flexible foil lid portion provides for an increased sensitivity of the highly sensitive flexible foil lid portion, and the cavity formed by the rigid base portion and the highly sensitive flexible foil lid portion is capable of containing a volume of 1 milliliter to 20 milliliters of the liquid, and the highly sensitive flexible foil lid portion is configured to respond to a pressure differential created by dispensing a liquid volume as small as 0.5 microliters;
• a pump;
• a dispensing tip positionable towards an eye of the individual to dispense the liquid onto a surface of an eye or into an area protected by an eyelid;
• and
• a liquid fluid path providing a fluid connection between the self-collapsible medical grade liquid reservoir, the pump and the dispensing tip.
