Abstract
Abstract A device for viewing the cervix and vaginal segment of a human uterus has a plurality of blades removably mounted on a holder. The blades are elongated transparent members and have an internal cavity closed near one end of the blade and open at the opposite end. The cavity is relatively wider in one direction and relatively narrower in another direction with the walls adjacent the narrower sides relatively weaker than the walls adjacent the wider sides.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
68 words
A body cavity speculum blade comprising; an elongated transparent plastic member including an internal cavity closed nearer one end of said blade and open at the opposite end; said blade cavity being relatively wider in one direction and relatively narrower in another direction transverse to the length of said blade such that the walls adjacent the narrower sides are relatively weaker than the walls adjacent the wider sides.
Claim 2
Dependent Claim
68 words
A body cavity speculum blade comprising; an elongated transparent plastic member including an internal cavity closed nearer one end of said blade and open at the opposite end; said blade cavity being relatively wider in one direction and relatively narrower in another direction transverse to the length of said blade such that the walls adjacent the narrower sides are relatively weaker than the walls adjacent the wider sides.
Claim 3
Dependent Claim
51 words
A body cavity speculum blade as defined in claim 1 wherein the end of said blade having the closed end of said internal cavity, has a curved portion for use within the body cavity and the closed end of said blade cavity is curved to conform to said curved blade portion.
Claim 4
Dependent Claim
31 words
A body cavity speculum blade as defined in claim 1 wherein said blade is curved and said blade cavity is similarly curved for use of said blade within the body cavity.
Claim 5
Dependent Claim
71 words
A body cavity speculum blade comprising; an elongated body; connecting means on one end of said body for temporarily connecting said blade to a speculum; means on the other end of said body for engaging a body portion within the body cavity and applying a force thereto in a direction along the length of said blade; and said connecting means further comprising a breakaway body portion for releasing said connecting means.
Claim 6
Dependent Claim
