Abstract
Abstract A radiation guard suitable for use in conjunction with a diagnostic table and penetrable by the hands of an operator to facilitate moving or examining a patient positioned on a table. In accordance with the invention there is provided a supportive frame mountable at about an edge of the table so as to extend vertically from about the edge, the frame comprising at least a pair of spaced bars. A plurality of strips of flexible radiation shielding material are mounted across the bars in closely spaced relationship, the strips being mounted sufficiently close together to prevent substantial radiation leakage through the frame. The hands of an operator can be inserted between the adjacent strips to manually reposition or examine a patient while protecting most of the operator's body from substantial radiation.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
116 words
A radiation guard suitable for use in conjunction with a diagnostic table and penetrable by the hands of an operator to facilitate examining or moving a patient on the table, comprising: a supportive frame mountable at about an edge of said table so as to extend normally from said edge, said frame comprising at least one pair of spaced bars; and a plurality of strips of flexible radiation shielding material mounted across said bars in closely spaced relationship, said strips being mounted sufficiently close together to prevent substantial radiation leakage through said frame, whereby the hands of an operator can be inserted between adjacent strips to touch a patient without exposing the operator to substantial radiation.
