Precision lid retracting eyedropper device
First Claim
1. a precision lid retracting eyedropper device comprising a third embodiment of said precision lid retracting eyedropper device where a first embodiment comprises:
- 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 foot on the upper portion of the orbital ridge near the eyebrow and the other J foot on the lower portion of the orbital ridge near the cheek bone;
so that when the said squeezes said legs together, then rests said J 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 fist tubular member;
said outlet check valve of said pump assembly connected by a second tubular member to a downwardly disposed exit aperture;
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.

6. A variation on said first embodiment of said precision lid retracting eyedropper device as claimed in claim one wherein said pump assembly is positioned in a vertical position and said piston slidably impinges on a rigid elongate pivotal member terminating in a tube compressing foot member which can impinge upon said resilient tubular pump member causing said solution to be expelled into said user'"'"'s eye.
