Abstract

Self diagnostic devices and methods for detecting a physical condition of a female based on a property of a vaginal secretion of the female are provided. The device comprises: a region of the device which receives the vaginal secretion from a body of the female and changes in appearance based on whether the vaginal secretion has a selected physical property; and a mounting mechanism for mounting the region of the device on the body adjacent to and external from the vagina such that the region receives secretions from the vagina and does not substantially lose water or other volatile components of the vaginal secretion due to vaporization. The device can be used for convenient diagnosis of vaginal infections such as infections caused by yeast, bacteria, viruses and other microorganisms.

Claims

1. A self diagnostic device for detecting a physical condition of a female based on a property of a vaginal secretion of the female, the device comprising:

a region of the device which is capable of receiving the vaginal secretion from a body of the female and changes in appearance based on whether the vaginal secretion has a selected physical property; and

a mounting mechanism for mounting the region of the device on the body adjacent to and external from the vagina such that the region receives secretions from the vagina and does not substantially lose water or other volatile components of the vaginal secretion due to vaporization.

2. A device according to claim 1 wherein the mounting mechanism includes an adhesive.

3. A device according to claim 1 wherein the mounting mechanism includes a hook material.

4. A device according to claim 1 wherein the mounting mechanism includes stitching.

5. A device according to claim 1 wherein the device further includes a transparent perforated barrier film over the region for preventing contact between the region and the body.

6. A device according to claim 1 wherein the region is in the form of fibers or threads stitched onto a wearable substrate.

7. A device according to claim 6 wherein the wearable substrate is selected from the group consisting of pantyliners and catamenial pads.

8. A self diagnostic device for detecting a physical condition of a female based on a property of a vaginal secretion of the female, the device comprising:

a region of the device including pH indicating material which is capable of receiving the vaginal secretion from a body of the female and changes in appearance based on a pH of the vaginal secretion; and

a mounting mechanism for mounting the region of the device on the body adjacent to and external from the vagina such that the region receives secretions from the vagina and does not substantially lose water or other volatile components of the vaginal secretion due to vaporization.

9. A device according to claim 8 wherein the region includes pH indicating material for indicating a pH of the vaginal secretion between about pH 3.5 and 5.5.

10. A device according to claim 8 wherein the device further includes a water permeable barrier film over the pH indicating material for preventing contact between the pH indicating material and the body.

11. A device according to claim 8 wherein the pH indicating material includes dye imprinted on a wearable substrate.

12. A device according to claim 11 wherein the wearable substrate is selected from the group consisting of pantyliners and catamenial pads.

13. A self diagnostic method for detecting a physical condition based on a property of a vaginal secretion, the method comprising:

wearing a device adjacent to and external from a vagina of a body such that the device is positioned to receive secretions from the vagina, the device having a region which receives the secretion and changes in appearance based on whether the vaginal secretion has a physical property;

removing the device from adjacent to the vagina after a time for a sufficient quantity of vaginal secretions to be received by the device; and

observing the region of the device in order to determine whether the region has changed in appearance so as to indicate that the vaginal secretion has the physical property.
