Abstract
Abstract The present invention features essentially only two relatively movable components, of which an outer sheath provides a forwardly curved path, a flexible mouth and a forwardly extending reference foot, and an inner flexible shaft has a forward element, which serves to open the mouth and to collect a mucus specimen when the flexible shaft moves forwardly and which serves to protect the mucus specimen and to close the mouth when the flexible shaft moves rearwardly. A probe is provided for inserting a test element into the vaginal cavity while shielding it from intermediate vaginal contact, for positioning the test element precisely in contact with the cervical os in order to collect a specimen of cervical material therefrom, and for retrieving the test element and the specimen from the vaginal cavity while shielding them from intermediate vaginal contact.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
260 words
A vaginal probe comprising: (a) sheath means characterized substantially by an original shape extending substantially along an axis of elongation for insertion into the vaginal cavity, said sheath means including forward extremity means connected thereto and intermediate mouth means, said sheath means being sufficiently rigid to provide a passage therethrough and to substantially maintain said original shape during said insertion; (b) shaft means having a rigid rearward portion and a semi-rigid forward portion for causing closing of said mouth means when in one condition and causing opening of said mouth means when in another condition; (c) specimen sampling means for confinement within said sheath means when in one condition and for protrusion through said mouth means when in another condition, said specimen sampling means extending through a predetermined region, when in said other condition, from said mouth means to the cervical os; (d) said specimen means being confined within said sheath means when said sheath means is inserted into and is withdrawn from the vaginal cavity; (e) a control means, said specimen means being in contact with the cervical os when said extremity means is seated in the posterior fornix, said control means is in one condition so that said mouth means is open, and said specimen means is in one condition so that it protrudes through said mouth means; (f) said forward extremity means having a configuration for seating in the posterior fornix and being a mechanical reference ranging in length along said axis from 1 to 5 centimeters and maintaining said length along said axis during said insertion.
Claim 2
Dependent Claim
260 words
A vaginal probe comprising: (a) sheath means characterized substantially by an original shape extending substantially along an axis of elongation for insertion into the vaginal cavity, said sheath means including forward extremity means connected thereto and intermediate mouth means, said sheath means being sufficiently rigid to provide a passage therethrough and to substantially maintain said original shape during said insertion; (b) shaft means having a rigid rearward portion and a semi-rigid forward portion for causing closing of said mouth means when in one condition and causing opening of said mouth means when in another condition; (c) specimen sampling means for confinement within said sheath means when in one condition and for protrusion through said mouth means when in another condition, said specimen sampling means extending through a predetermined region, when in said other condition, from said mouth means to the cervical os; (d) said specimen means being confined within said sheath means when said sheath means is inserted into and is withdrawn from the vaginal cavity; (e) a control means, said specimen means being in contact with the cervical os when said extremity means is seated in the posterior fornix, said control means is in one condition so that said mouth means is open, and said specimen means is in one condition so that it protrudes through said mouth means; (f) said forward extremity means having a configuration for seating in the posterior fornix and being a mechanical reference ranging in length along said axis from 1 to 5 centimeters and maintaining said length along said axis during said insertion.
Claim 3
Dependent Claim
23 words
The probe of claim 1 wherein said sheath means defines a path therewithin having a straight rearward portion and a curved forward portion.
Claim 4
Dependent Claim
25 words
The probe of claim 1 wherein said mouth means is provided by a cap that is removably connected to the remainder of said sheath means.
Claim 5
Dependent Claim
40 words
The probe of claim 1 wherein said shaft means is slidable in said sheath means between an inoperative position at which it is confined within said sheath means and an operative position at which it protrudes through said mouth means.
Claim 6
Dependent Claim
45 words
The probe of claim 1 wherein said specimen means includes a test element at its forward extremity, said forward extremity having an inoperative position at which it is confined within said sheath means and an operative position at which it projects from said sheath means.
Claim 7
Dependent Claim
39 words
The probe of claim 1 wherein said shaft means includes a flexible intermediate portion having a spine and a plurality of beads, said beads being of substantially the same maximum cross-sectional extent as said passage of said sheath means.
Claim 8
Dependent Claim
29 words
The probe of claim 1 wherein said rigid rearward portion has a controlling diameter that is substantially the same as the diameter of said passage of said sheath means.
Claim 9
Dependent Claim
266 words
A vaginal probe comprising: (a) sheath means characterized substantially by an original shape extending substantially along an axis of elongation for insertion into the vaginal cavity, said sheath means including forward extremity means connected thereto and intermediate mouth means, said sheath means being sufficiently rigid to provide a passage therethrough and to substantially maintain said original shape during said insertion; (b) shaft means having a rearward portion and a forward portion for causing closing of said mouth means when in one condition and causing opening of said mouth means when in another condition; (c) specimen sampling means at the forward extremity of said shaft means for confinement with said sheath means when in one condition and for protrusion through said mouth means when in another condition, said specimen sampling means extending through a predetermined region, when in said other condition, from said mouth means to the cervical os; (d) said specimen means being confined within said sheath means when said sheath means is inserted into and is withdrawn from the vaginal cavity; (e) a control means, said specimen means being in contact with the cervical os when said extremity means is seated in the posterior fornix, said control means is in one condition so that said mouth means is open, and said specimen means is in one condition so that it protrudes through said mouth means; (f) said forward extremity means having a configuration for seating in the posterior fornix and being a mechanical reference ranging in length along said axis from 1 to 5 centimeters and maintaining said length along said axis during said insertion.
