Abstract

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. Processes are provided for retrieving specimens in the form of tissue or mucus.

Claims

1. 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 substantially maintain said original shape during said insertion;

(b) control means 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 curvature when in said other condition, from said mouth means to the cervical os

(d) said specimen sampling means being confined within said sheath means when said sheath means is inserted into and is withdrawn from the vaginal cavity;

(e) 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 said one condition so that said mouth means is open, and said specimen means is in said 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.

2. The probe of claim 1 wherein said mouth means is provided by transverse portion that is integral with portions of said sheath means and that is defined by slits in said transverse portion.

3. The probe of claim 1 wherein said control means includes a tube 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.

4. The probe of claim 1 wherein said specimen means includes a rod having a test element at its forward extremity, said forward extremity having an inoperative position at which it is confined within said control means and an operative position at which it projects from said control means.

5. The probe of claim 1 wherein said specimen means includes an element with a ridged face for contacting the cervical os.

6. The probe of claim 1 wherein said specimen means includes a shaft and a pivoted element thereon, said pivoted element having a surface for contact with the cervical os.

7. The probe of claim 1 wherein said specimen means includes a sponge.

8. A vaginal probe comprising:

(a) a sheath and a forward extremity connected thereto for insertion into the vaginal cavity, said sheath including an intermediate mouth, said sheath and said extremity being composed of a resilient polymer and being developed along an axis, said mouth being generally transverse with respect to said axis, said sheath and said extremity being characterized by an original shape extending substantially along an axis of elongation and being sufficiently rigid to maintain said original shape during said insertion;

(b) a movable control within said sheath, said control causing closing of said mouth when in one condition and causing opening of said mouth when in another condition;

(c) a shaft having a test element at an end, said shaft being reciprocable with respect to said sheath, said test element being confined within said sheath when in one condition and being protruded through said mouth when in another condition;

said shaft extending through a curvature when in said other condition from said mouth to the cervical os;

(d) said test element being confined within said sheath when said sheath is inserted into and is withdrawn from the vaginal cavity;

(e) said test element being in contact with the cervical os when said extremity is seated in the posterior fornix, said control is in said one condition so that said mouth means is open, and said test element is in said one condition so that it protrudes through said mouth;

(f) said extremity 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.

9. The probe of claim 8 wherein said mouth is provided by transverse portion that is integral with portions of said sheath and that is defined by slits in said transverse portion.

10. The probe of claim 8 wherein said tube is slidable in said sheath between an inoperative position at which it is confined within said sheath and an operative position at which it protrudes through said mouth.

11. The probe of claim 8 wherein said test element includes a rod, said forward extremity having an inoperative position at which it is confined within said tube and an operative position at which it projects from said tube.

12. The probe of claim 8 wherein said test element includes a ridged face for contacting the cervical os.

13. The probe of claim 8 wherein said test element includes a shaft and a pivoted element thereon, said pivoted element having a surface for contact with the cervical os.

14. The probe of claim 8 wherein said test element includes a sponge.
