Abstract
Abstract A device is disclosed for home use detection of cervical and vaginal carcinoma. The device comprises a probe of various designs including an aspiration device or a swab for removing cells from the vagina or cervix. The probe is encased to provide a sterile environment. The device includes a container having a rupturable membrane for maintaining a solution in a sterile environment prior to breaking of the rupturable membrane. The rupturable membrane is established for being severed by the probe enabling the probe containing the removed cell to be immersed in the solution in the container. In one embodiment, the container contains a fixing solution for reacting with the cells on the probe enabling the transfer of the sample cells to a testing laboratory. In another embodiment of the invention, the container contains an iodine soluition for reacting with the sample cells. The color of the stained sample cells is then compared to a color chart for providing an immediate indication of the test results.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
239 words
A kit for the home detection of squamous cell carcinoma of the cervix and vagina comprising: a probe including a semi-rigid member; said semi-rigid member having a proximal end and a distal end with a swab at said distal end of said semi-rigid member for collecting and removing cells in use from the vagina and cervix; means for encasing said probe in a sterile environment prior to use; a container; a weakened region formed on said container defining a frangible portion and a body portion and for enabling said frangible portion to be severed from said body portion; said body portion having a rupturable membrane for maintaining an iodine stain in a sterile environment prior to the breaking of said rupturable membrane; said swab being configured such that said swab is able to rupture said rupturable membrane of said body portion to permit said swab to be immersed into said iodine stain when said swab is positioned within said container; said frangible portion of said container being severable from said body portion of said container to enable said swab to reach and to break said rupturable membrane of said body portion thereby permitting said swab to be immersed into said iodine stain; and a comparison chart comprising a plurality of colors for comparing the extend of stain by the iodine of the cells present on said swab to enable the consumer to determine the presence of squamous cell carcinoma.
