Precision Lid Retracting Eyedropper Device
First Claim
1. A precision lid retracting eyedropper device comprising:
- a hollow housing;
said housing having an aperture at its top most surface and a hollow cylindrical portion at its bottom most surface;
a pair of resilient downwardly facing legs integrally attached to the bottom surface of said hollow housing;
said legs terminating opposing J-shaped feet;
a plurality of friction inducing strips attached to the underside of said J-shaped feet;
said legs spaced sufficiently apart to allow a user to place one said J-shaped foot on the upper portion of the orbital ridge near the eyebrow and the other J-shaped foot on the lower portion of the orbital ridge near the cheek bone;
such that when the user squeezes said legs together, then rests said J-shaped feet on said upper and lower eye socket, and then releases said legs, the eyelids of the user are forced to remain open because of the outward spring action of said legs;
an eye drop solution storage chamber located within said hollow housing;
a pump assembly located within said hollow housing;
said pump assembly comprised of a resilient tubular member having an inwardly directed check valve frictionally inserted in one end and an outwardly directed check valve frictionally inserted at the opposite end;
an elongate piston member whose bottom end impinges on the central portion of said resilient tubular pump member and whose upper end exits said top housing aperture terminates at its top end in a push button;
said solution storage chamber connected to said inlet check valve by a first tubular member;
said outlet check valve of said pump assembly connected by a second tubular member to a downwardly disposed exit aperture; and
said second tubular member held in place by said cylindrical housing member;
so that when said user presses on said push button, said piston impinges on said resilient pump tube and forces a precise amount of eye drop solution out of said outwardly directed check valve and out said exit aperture and into said user'"'"'s eye.

Abstract
Precision lid retracting eyedropper device with a hollow, rigid housing having an upper aperture that allows a push button topped piston to enter the housing where the piston can impinge on a resilient tubular member that is part of a pump assembly. The housing also includes a solution storing chamber that feeds solution to the pump assembly. A solution exit tube attached to the outgoing portion of the pump assembly emanates from the bottom part of the housing and can be directed towards the user'"'"'s eye. Integral downwardly facing resilient legs are placed just above and below the user'"'"'s orbital ridge so that when the legs are squeezed and released, the user'"'"'s eye lids are forced open allowing the user to dispense a precise amount of solution into his or her eye. A precision eye drop solution container having the ability to retain and dispense a precise single portion of eye drop solution each time the user depresses an actuator device located on and within the housing of the container. The container includes downwardly facing legs and feet that are parallel to each other and spaced so that the foot of each leg can align and make contact with the upper and lower orbital socket of the user. The feet have rubber-like under surfaces whose soft yet gripping quality acts to help hold the eye lids of the user in the open position. The dispensing action can be automated and an LED light indicating that dispensing has occurred.

17. A preferred embodiment of the precision eye dropper comprised of a hollow housing;
-
a pair of downwardly facing, non-resilient legs terminating in a pair of concave shaped perpendicularly disposed feet and spaced so that one said foot engages the upper orbit socket of the user'"'"'s eye and the other foot engages the lower orbit socket of the user'"'"'s eye; said housing containing a first flexible bladder, a second flexible bladder, a first and a second one way valve, a rubber stopper insert, a plunger rod and a dispensing tip; said first bladder being doughnut shaped and having an integral tube extension that attaches to said first check valve; said plunger rod extending down through said doughnut shaped first bladder; said first check valve communicating an orifice at the top of said second bladder; said second check valve communicating with an orifice at the bottom of said second bladder; the bottom of said second check valve communicating with said dispensing tip; so that when a person presses on the top of said plunger rod, liquid stored within said first bladder is forced through said extension tube into said first one way valve and into said second bladder; said plunger causing compression in said second bladder and causing said eye drop solution stored within said second bladder to be expelled through said second one way valve and out of said dispensing tip into the user'"'"'s eye. - View Dependent Claims (18, 19, 20, 21)

22. A precision eye drop dispenser comprising;
- a hollow housing;
a pair of non-resilient downwardly disposed legs terminating in a pair of concave feet;said legs parallel spaced and fixedly attached to the underside of said hollow housing; said hollow housing enclosing a U shaped track, a drive disk, a ratchet drive disk, a spring biased plunger rod, a ratchet drive arm and a pawl for said ratchet drive arm; said drive disk and said ratchet disk concentrically and fixedly attached to each other; said drive disk having a shaft member; said shaft member rotatably retained within a centrally located aperture on a flat wall of said housing; said ratchet drive arm attached to said plunger rod in a spaced and parallel manner; said ratchet drive arm terminating at its lowest point in a pawl assembly;
said pawl capable of forcefully and upwardly engaging said ratchet drive disk thereby causing a plurality of radially displaced posts attached to the perimeter of said drive disk to rotate in a clockwise manner;and in turn causing a portion of an eye drop portion retaining strip, slidably retained within said track, to be advanced forward one portion position; said plunger rod slidably retained in a vertical manner within said hollow housing; said plunger rod tip capable of depressing a dome shaped portion located on the top side of said eye drop retaining strip thereby causing a precise portion of said eye drop solution to be dispensed out of a cone shaped, cap covered portion affixed to the bottom side of said eye drop portion retaining strip.
