Abstract:
1. A precision lid retracting eyedropper device comprising: a hollow housing; said housing having an aperture at a first surface thereof and a hollow cylindrical portion at a second surface thereof; a pair of resilient legs integrally attached to the second surface of said hollow housing; said legs terminating opposing J shaped feet; a plurality of friction inducing strips attached to 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 said legs are squeezed together, then said J shaped feet are rested on said upper and lower portions of the orbital ridge, and then said legs are released, the eyelids of the user are forced to remain open because of an 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 comprising a resilient tubular member having an inwardly directed check valve positioned in a first end thereof and an outwardly directed check valve positioned in a second end thereof; an elongate piston member having a first end impinging on a central portion of said resilient tubular member and a second end exiting said housing through the aperture in the first surface thereof where the piston member terminates in a push button; said solution storage chamber connected to said inwardly directed check valve by a first tubular member; said outwardly directed check valve of said pump assembly connected by a second tubular member to an exit aperture; said second tubular member held in place by said hollow cylindrical portion of said housing; so that when said user presses on said push button, said piston impinges on said resilient tubular member of said pump assembly 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.
