Apparatus and Method of Washed Hand and Object Detection
First Claim
1. A system for monitoring an individual'"'"'s hand hygiene comprising:
- a hand washing substance comprising a chemical odor marker, said odor marker comprising a detectable odor marker vapor; and
a detector for detecting said odor marker vapor emanating from the individual'"'"'s hand containing said hand washing substance wherein said hand is placed proximate to said detector without said hand physically touching said detector, said detector comprising a sensor and one or more indicators operably in communication with said sensor, said detector generating a signal based on the results of said detection.

Abstract
The present invention is a method and apparatus for contaminant detection of body parts, such as hands, and or their coverings, such as clean room suits or gloves, and small objects. Particularly, the method and apparatus involve collecting air samples containing aerosolized contaminate particles from the objects and analyzing the sample for presence of a contaminate. Aerosol lab-on-a-chip and/or electronic nose devices are utilized for the detection of contaminant particles. Also included is a system and method for monitoring an individual'"'"'s hand hygiene or an object'"'"'s cleanliness using a washing substance containing one or more chemical odor markers and a touchless detector for detecting the odor markers and generating a signal based on such detection. The detector may be handheld or portable. The system may also employ a mechanism for identifying the individual, and may employ one or more remote devices for monitoring or indicating the results of the detection.
