Abstract
Abstract A dilating speculum comprises a tubular body (8) adapted for connection at one end to an eye-piece and light source, a tubular probes (11) adapted to be inserted into the vagina or other body cavity and comprising an outer probe part (13) detachably secured to the tubular body (8) and an inner probe part (12) lodged within the bore of the outer part (13). An inflatable latex (15) sheath surrounds a length of the probe (11) and is sealed thereto at each end of that length. The seal at one end is effected by virtue of an end portion of the sheath (15) being sandwiched between the two probe parts (12, 13) and at the other end by a stretched elastic ring (35) encircling the probe (11) and sheath (15). A passage (24, 23, 25, 28, 29) through the body (8) and probe (11) allows the sheath (15) to be inflated between the seals.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
90 words
A speculum, for use in examining the interior of a body cavity, comprising a tubular body having two ends, a tubular probe adapted to enter said body cavity detachably secured to said tubular body so as to project beyond one of the ends thereof, an inflatable element encircling said probe, and means to inflate said element, and wherein said tubular body and said tubular probe are at least partly made of transparent material to permit light to be transmitted from end to end of said speculum through said transparent material.
Claim 2
Dependent Claim
90 words
A speculum, for use in examining the interior of a body cavity, comprising a tubular body having two ends, a tubular probe adapted to enter said body cavity detachably secured to said tubular body so as to project beyond one of the ends thereof, an inflatable element encircling said probe, and means to inflate said element, and wherein said tubular body and said tubular probe are at least partly made of transparent material to permit light to be transmitted from end to end of said speculum through said transparent material.
Claim 3
Dependent Claim
36 words
A speculum according to claim 1 wherein the inflatable element is in the form of a sheath of film covering a length of the probe and sealed to the probe at each end of that length.
Claim 4
Dependent Claim
29 words
A speculum according to claim 2 wherein said sheath of film extends as an uninflated skirt beyond one seal so as to at least partly cover said tubular body.
Claim 5
Dependent Claim
28 words
A speculum according to claim 2 wherein said means to inflate comprise means to admit gas to a space between the sheath and said length of the probe.
Claim 6
Dependent Claim
24 words
A speculum according to claim 1 wherein the other end of said tubular body is adapted for connection to an eye-piece and light source.
Claim 7
Dependent Claim
18 words
A speculum according to claim 1 further comprising tubular liner extending through the bore of said tubular body.
Claim 8
Dependent Claim
34 words
A speculum according to claim 1 wherein said probe comprises an outer probe part detachably secured to said tubular body and an inner probe part lodged within the bore of said outer probe part.
Claim 9
Dependent Claim
71 words
A speculum according to claim 7 wherein the inflatable element is in the form of a sheath of film covering a length of the probe and sealed to the probe at each end of that length, and wherein the seal at one end of that length of probe is effected by virtue of an end portion of the sheath being sandwiched between said outer probe part and said inner probe part.
