Total Claims: 7
Claim 1
Independent Claim
200 words
An X-ray shield for protecting an operator physically gripping a patient upon an X-ray table during irradation and adapted for removable attachment to a diagnostic table comprising: a frame having vertical legs depending from a horizontal cross piece; a pair of feet connected one to the bottom of each said legs in angularly adjustable relation thereto and being adapted for slidable engagement with at least one of two tracks extending along the top of said table for mounting said frame in adjustable position on said table in extension above the table; an upper sheet of flexible radiation resistance material depending from said crosspiece between said legs with a lead glass window therein, and removably attached to said legs for protecting said operator standing on the opposite side of said shield from the table from stray X-rays and secondary radiation; a lower sheet of flexible radiation resistant material having attachment means along the top thereof adapted to cooperate with attachment means along the bottom of said upper sheet for removably engaging said sheets in overlapping relation whereby said lower sheet is free to move about the top thereof for extension over said table to protect the hands of said operator thereat.
Claim 2
Dependent Claim
200 words
An X-ray shield for protecting an operator physically gripping a patient upon an X-ray table during irradation and adapted for removable attachment to a diagnostic table comprising: a frame having vertical legs depending from a horizontal cross piece; a pair of feet connected one to the bottom of each said legs in angularly adjustable relation thereto and being adapted for slidable engagement with at least one of two tracks extending along the top of said table for mounting said frame in adjustable position on said table in extension above the table; an upper sheet of flexible radiation resistance material depending from said crosspiece between said legs with a lead glass window therein, and removably attached to said legs for protecting said operator standing on the opposite side of said shield from the table from stray X-rays and secondary radiation; a lower sheet of flexible radiation resistant material having attachment means along the top thereof adapted to cooperate with attachment means along the bottom of said upper sheet for removably engaging said sheets in overlapping relation whereby said lower sheet is free to move about the top thereof for extension over said table to protect the hands of said operator thereat.
Claim 3
Dependent Claim
