Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
132 words
An X-ray eye shield for use during dental radiography comprising a radiolucent frame adapted to fit the contours of the head and two radiopaque lens cups attached to said frame in a manner which will bring the lens cups into conformity over the eye sockets when the shield is placed on the head of the patient, said lens cups being attached to said frame by passive hinges which permit adjustment of said lens cups into conformity over the eye sockets after the frame has been placed on the head of the patient, and being made of a material which effectively prevents passage of X-ray radiation, but X-ray radiation otherwise not being occluded by said eye shield so that the important anatomical landmarks necessary for accurate dental diagnosis may be X-rayed without distortion.
