Abstract
A finger guide (2) comprises first and second orthogonally-oriented portions (4,12) each comprising a pair of opposed converging surfaces (6,8;14,16) into which the end and the shank, respectively, of a finger for examination fit. Because of the relative orientation of the surfaces, movement of the finger relative to an examination surface (22) is reproducibly constrained.
