Patent ID: 7503899

Claim:
Apparatus for quick screening for vaginal moisture pH level as related to a pre-selected pH level, comprising a) a manipulable generally key shaped element including a probe insertible into the vagina, b) a pH indicator on one side of said element, said indicator characterized as producing a color which corresponds to pH level of vaginal moisture contacting the indicator, c) and a second indicator on another side of said element, said second indicator being elongated lengthwise of the element and being an amine indicator, d) a local comparison zone having a fixed color corresponding to a predetermined pH level, and positioned and shaped for quick color comparison with the color of said pH indicator after pH indicator contact with vaginal moisture, said pH indicator having contact with vaginal moisture for visual comparison of the color of said zone with the color of said pH indicator, e) said pH indicator and said comparison zone spaced in mutual proximity on and lengthwise of the probe, and having like cross dimensions between 3/16 and ⅜ inch, and to have generally arcuate peripheral shapes, f) and wherein said element includes an enlarged substantially flat handle from which the probe projects longitudinally to be gripped between the user's thumb and forefinger, the handle having two laterally shaped edges presented toward said test site or sites and spaced generally longitudinally therefrom to limit probe longitudinal insertion into the vagina, said pH indicator and said local comparison zone being aligned on a line which extends between said two edges, and both having curved edges facing oppositely and convexly away from said line, and protruding at opposite edges of said probe.
