CA 2732786

A method and apparatus for non-invasive analysis of an oral fluid, such as saliva, to determine the presence and the level of a certain constituent in the saliva. The apparatus includes a user-friendly, lolli-pop like construction that is self-contained and provides a user with a method to obtain a saliva sample by sucking or licking a pop-like head of the apparatus. A reagent on the apparatus is exposed to the saliva sample and interacts with the certain constituent to produce a color change made visible on the apparatus. The resulting visible color change is then matched visually with a corresponding color on a color-coded alphanumeric gauge for determining the presence and the level of the certain constituent in the saliva sample, thereby providing quick and simple monitoring of health conditions and concerns.

La présente invention concerne un procédé et un appareil danalyse non invasive dun fluide buccal, tel que la salive, pour déterminer la présence et la concentration dun certain élément constitutif de la salive. Lappareil comprend une structure en forme de sucette facile à utiliser qui est indépendante et permet à un utilisateur dobtenir un échantillon de salive par succion ou coups de langue sur la tête de lappareil en forme de sucette. Un réactif sur lappareil est exposé à léchantillon de salive et entre en action avec ledit élément  constitutif pour produire un changement de couleur visible sur lappareil. Le changement de couleur visible obtenu est alors comparé visuellement avec une couleur correspondante sur un indicateur alphanumérique à code-couleur pour déterminer la présence et la concentration dudit élément constitutif dans léchantillon de salive, ce qui permet de fournir une surveillance rapide et simple dun état de santé.
