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 cells 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 solution 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: 12
Claim 1
Independent Claim
296 words
A device for the detection of cervical and vaginal carcinomas comprising: an elongated tube; said elongated tube including an internal and an external wall; a rounded end disposed at one end of said elongated tube; said rounded end of said elongated tube defining a plurality of orifices; said elongated tube includes an integral shield disposed adjacent the end of the elongated tube remote from said rounded end for limiting penetration of said elongated tube into the vagina; a flexible diaphragm, having a peripheral edge disposed within said elongated tube; said peripheral edge being circumferentially sealed to the inner wall of said elongated tube thereby fixing the location of said flexible diaphragm within said elongated tube and dividing said elongated tube into a first portion which in part defines said rounded end of said elongated tube and a second portion which houses a plunger; said plunger comprising a piston connected to a piston rod having a trigger; said plunger is disposed within said elongated tube and cooperates with said flexible diaphragm for drawing a vaginal specimen into said elongated tube upon the axial movement of said plunger by reciprocation of said trigger thereby enabling said plunger to be reciprocated within and relative to said elongated tube which results in reciprocation of said flexible diaphragm providing aspiration of the vaginal specimen through said orifices and into said elongated tube; a fixing container cooperating with said elongated tube; said fixing container including a cylindrical portion; said fixing container further including an ampule for containing a fixing solution; a rupturable membrane disposed between said ampule and said cylindrical portion; and said cylindrical portion slidably receiving said rounded end of said elongated tube to enable the rupture of said rupturable membrane enabling the fixing solution and the vaginal specimen to mix.
Claim 2
Independent Claim
296 words
A device for the detection of cervical and vaginal carcinomas comprising: an elongated tube; said elongated tube including an internal and an external wall; a rounded end disposed at one end of said elongated tube; said rounded end of said elongated tube defining a plurality of orifices; said elongated tube includes an integral shield disposed adjacent the end of the elongated tube remote from said rounded end for limiting penetration of said elongated tube into the vagina; a flexible diaphragm, having a peripheral edge disposed within said elongated tube; said peripheral edge being circumferentially sealed to the inner wall of said elongated tube thereby fixing the location of said flexible diaphragm within said elongated tube and dividing said elongated tube into a first portion which in part defines said rounded end of said elongated tube and a second portion which houses a plunger; said plunger comprising a piston connected to a piston rod having a trigger; said plunger is disposed within said elongated tube and cooperates with said flexible diaphragm for drawing a vaginal specimen into said elongated tube upon the axial movement of said plunger by reciprocation of said trigger thereby enabling said plunger to be reciprocated within and relative to said elongated tube which results in reciprocation of said flexible diaphragm providing aspiration of the vaginal specimen through said orifices and into said elongated tube; a fixing container cooperating with said elongated tube; said fixing container including a cylindrical portion; said fixing container further including an ampule for containing a fixing solution; a rupturable membrane disposed between said ampule and said cylindrical portion; and said cylindrical portion slidably receiving said rounded end of said elongated tube to enable the rupture of said rupturable membrane enabling the fixing solution and the vaginal specimen to mix.
Claim 3
Dependent Claim
41 words
A device as set forth in claim 1 wherein said elongated tube includes a weakened section disposed adjacent said external wall of said elongated tube around the circumference of said elongated tube remote from said rounded end and said flexible diaphragm.
Claim 4
Dependent Claim
40 words
A device as set forth in claim 1 wherein said elongated tube includes internally projecting longitudinally extending splines which cooperate with corresponding longitudinally extending grooves disposed along said plunger for preventing rotation of said plunger relative to said elongated tube.
Claim 5
Dependent Claim
33 words
A device as set forth in claim 1 wherein said elongated tube includes internally projecting stops which cooperate with said plunger to limit longitudinal movement of said plunger relative to said elongated tube.
Claim 6
Dependent Claim
49 words
A device as set forth in claim 4 wherein said internally projecting stops include a first set of stops for limiting the approach of said plunger relative to said flexible diaphragm and a second set of stops for limiting the movement of said plunger away from said flexible diaphragm.
Claim 7
Dependent Claim
17 words
A device as set forth in claim 1 wherein said flexible diaphragm includes a central bulbous portion.
Claim 8
Dependent Claim
19 words
a device as set forth in claim 6 wherein said central bulbous portion is releasably secured to said plunger.
Claim 9
Dependent Claim
47 words
A device as set forth in claim 1 wherein said cylindrical portion includes inwardly projecting ears which cooperate with an annular groove defined by the external wall of said elongated tube to lock the external wall of said elongated tube into sealing engagement with said cylindrical portion.
Claim 10
Dependent Claim
34 words
A device as set forth in claim 8 wherein said annular groove is located at a greater distance from said rounded end than the distance between said inwardly projecting ears and said rupturable membrane.
Claim 11
Dependent Claim
27 words
A device as set forth in claim 9 wherein a rim of said ampoule includes an annular ridge disposed adjacent a first side of said rupturable membrane.
Claim 12
Dependent Claim
39 words
A device as set forth in claim 1 wherein said rupturable membrane includes an annular portion of reduced thickness which ruptures when said rounded end of said elongated tube is inserted into said cylindrical portion and into said ampoule.
