Intra-vaginal prolapse diagnostic instrument

Claim 1

An intra-vaginal diagnostic instrument for detecting utero-vaginal prolapse comprising an elongated cylindrical plunger including a distal end and a proximal end, means defining an annular notch on said plunger, said distal end of said plunger including a bulbous terminal, and said proximal end including a pinched zone of diminished diameter, a tubular body encircling said plunger and including a distal end and a proximal end, said distal end of said tubular body terminating in a generally concave flange configured to engage the entrance of the vagina, an annular flange positioned on the proximal end of said tubular body, a scale tube mounted on the exterior of said tubular body for sliding movement thereon between said annular flange and said concave flange, measuring indicia on said scale tube configured to cooperate with said annular notch on said plunger to provide an indication of the depth of penetration of the bulbous end portion of said plunger into the vagina when said plunger is moved thereinto relative to said tubular body and said annular notch on said plunger is positioned beneath said measuring indicia on said scale tube.
