Filed:

Mar 10, 2009

Appl. No.:

12/401051

Inventors:

Russell Bazemore - Grant AL, US
Alastair Winn - Santa Barbara CA, US
Thomas McKee - Madison AL, US

International Classification:

A61B 5/097
A61B 5/00

US Classification:

600532, 600573

Abstract:

The present disclosure generally pertains to chemical extraction apparatuses and methods for extracting volatile, semi-volatile, and non-volatile chemicals from a user's oral cavity. In one exemplary embodiment, a chemical extraction apparatus is composed of absorbent material, which is positioned within the oral cavity of a user for a period of time. Volatile, semi-volatile, and non-volatile chemicals are extracted from the breath and saliva of the user. By keeping the absorbent material in the oral cavity for an extended period of time, such as several minutes or hours depending on the types of materials selected, even trace levels of a chemical can be concentrated in the absorbent material thereby enabling conventional analytical techniques to detect the chemical.

International Classification:

A61B 5/097
A61M 16/00

US Classification:

600532, 12820527

Abstract:

A chemical extraction apparatus has absorbent material for absorbing or adsorbing volatile chemicals from a breath of a user. The chemical extraction apparatus is positioned within such that breaths from the user flow over the absorbent material thereby causing volatile chemicals in the breaths to absorb or adsorb into the absorbent material. The absorbent material is then analyzed to determine the amount of chemicals absorbed or adsorbed into the absorbent material. Based on such analysis, various diseases or conditions can be detected or diagnosed.
