ABSTRACT:
A combined eyelid retracting and eye flushing device that permits an operator to retract the upper eyelid of a patient for selective eye flushing or other treatment. The device comprises a frame with spaced apart ends. One end forms an integral handle and the other end defines a peripheral edge that forms an arcuate lip for securing the eyelid to the frame. A plurality of spaced apart orifices penetrate the lip to distribute suction along the entire edge surface. An integral flushing system attached to the frame near the lip comprises an irrigator with a hollow stem protruding outwardly from one side of the frame and an aspirator with a hollow stem protruding oppositely. The irrigation stem terminates in a nozzle that selectively sprays liquids upon the eye and the aspiration stem terminates in a receptive orifice that drains run-off liquids and entrained contaminants therefrom. The lip, irrigator and aspirator all connect to a plurality of channels housed inside the frame. The channels establish fluid flow communication through the frame from the lip, irrigator and aspirator to external vacuum suction, liquid and storage sources. When the device is deployed, an operator aligns the lip along the upper eyelashes and the aspirator stem adjacent the inner terminus of the palpebral fissure. The upper eyelid is then seated against the frame edge with vacuum suctioning through the lip. The upper eyelid is retracted as the frame rests upon the patient's forehead and superciliary arch.
