Abstract
Abstract The invention overcomes the problem of excessive dilation of the introitus, and also permits the interior of the vagina to be dilated independently of the introitus. Essentially, the vaginal speculum (1) comprises an introitus engaging ring member (2) and a pair of vagina engaging members (3,4) of arcuate shape slidable through the ring member (2). The introitus engaging ring member (2) is inserted into the introitus and the vagina engaging members (3,4) are moved through the ring member (2) in the direction of the arrow A. As the vagina engaging members (3,4) are moved through the ring member (2) into the vagina, ends 9 and 10 move apart, thereby dilating the interior of the vagina. In another embodiment of the invention the vagina engaging members (3,4) are pivotally connected (30, 31) to the introitus engaging ring member (2).

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
47 words
A vaginal speculum of the type comprising a pair of elongated vagina engaging members (3,4) movable apart relative to each other and adapted to extend into the vagina, characterised in that the vagina engaging members (3,4) extend into the vagina from an introitus engaging ring member (2).
Claim 2
Dependent Claim
47 words
A vaginal speculum of the type comprising a pair of elongated vagina engaging members (3,4) movable apart relative to each other and adapted to extend into the vagina, characterised in that the vagina engaging members (3,4) extend into the vagina from an introitus engaging ring member (2).
Claim 3
Dependent Claim
30 words
A vaginal speculum as claimed in claim 1 characterised in that the introitus engaging ring member (2) is of substantially circular cross-section and adapted to extend partly into the vagina.
Claim 4
Dependent Claim
30 words
A vaginal speculum as claimed in claim 1 or 2 characterised in that the vagina engaging members (3,4) are slidable through the introitus engaging ring member (2) into the vagina.
Claim 5
Dependent Claim
27 words
A vaginal speculum as claimed in any of the preceding claims characterised in that at least one of the vagina engaging members (3,4) is of arcuate shape.
Claim 6
Dependent Claim
24 words
A vaginal speculum as claimed in any of the preceding claims characterised in that both the vagina engaging members (3,4) are of arcuate shape.
Claim 7
Dependent Claim
31 words
A vaginal speculum as claimed in any of the preceding claims characterised in that the vagina engaging members (3,4) are adapted to slide together through the introitus engaging ring member (2).
Claim 8
Dependent Claim
61 words
A vaginal speculum as claimed in any preceding claim characterized in that portions of the vagina engaging members (3,4) as they pass through the introitus engaging ring member (2), abut each other along abutting surfaces (11) adjacent corresponding longitudinal side edges (13) the said portions of the vagina engaging members (3,4) together forming an opening (12) for inspection of the vagina.
Claim 9
Dependent Claim
45 words
A vaginal speculum as claimed in claim 7 characterised in that each abutting surface (11) of the vagina engaging members (3,4) is provided with a friction surface (14) to cause the vagina engaging members (3,4) to move together through the introitus engaging ring member (2).
Claim 10
Dependent Claim
25 words
A vagina engaging speculum as claimed in any of the preceding claims characterised in that the vagina engaging members (3,4) are of substantially semi-circular cross-section.
Claim 11
Dependent Claim
45 words
A vaginal speculum as claimed in claims 1 or 2 characterised in that at least one of the vagina engaging members (3,4) is pivotally connected to the introitus engaging ring member (2) and means (35) to move the vagina engaging members (3,4) apart being provided.
Claim 12
Dependent Claim
26 words
A vaginal speculum as claimed in claim 10 characterised in that both vagina engaging members (3,4) are pivotally connected to the introitus engaging ring member (2).
Claim 13
Dependent Claim
66 words
A vaginal speculum as claimed in claims 10 or 11 characterised in that the means (35) to move the vagina engaging members (3,4) apart is provided by a pivotal member (35), the pivotal member (35) being pivotal on the inner surface (36) of one of the vagina engaging members (3,4) and extending therefrom to engage the inner surface (37) of the other vagina engaging member (3,4).
