Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
149 words
A hand held light source probe for use with transillumination apparatus for tumor detection in human female breasts comprising: a housing including a hollow heat insulating handle portions; a pipe having proximal and distal ends extending longitudinally from one end of said housing, curing through substantially 90°, and terminating at its distal end in a plane surface; a high intensity incandenscent reflectorized light source positioned in said housing to illuminate the proximal end of said light pipe; a fixed opaque light shield of substantially less area than the proximal end of said light pipe so positioned in the projected light pahh of said bulb between said bulb and said pipe as to positively prevent the presence of a focal spot from said source on the distal end of said light pipe; and means for positively circulating cooling air through said housing and over the outer surface of said bulb.
Claim 2
Dependent Claim
