Abstract

A handwash monitoring system and method for providing an alert when a person must wash her hands. A badge worn by the person is activated to register at least one of a visual, audible or tactile alarm after a specified time interval or by a beacon placed where contamination may occur when the badge enters the range of the beacon. The person must wash her hands according to a predetermined handwash procedure as set forth by visual and audible prompts issued by a base unit in a wash area in order to clear the badge alarm and advance a wash count.

16. The handwash monitoring system as set forth in claim 7, wherein said base unit communicates with said badge using wireless means.

17. The handwash monitoring system as set forth in claim 7, further comprising a plurality of beacons placed at locations where it is desired to communicate with said badge to register the hands-unwashed state when said badge is within a predetermined proximity to any one of said plurality of beacons.

18. The handwash monitoring system as set forth in claim 17, further comprising means for preventing said badge from registering the hands-unwashed state for a predetermined period of time upon said base unit detecting the person has correctly performed the predetermined handwash procedure to allow the person to exit said wash area and pass one or more of said plurality of beacons without registering the hands-unwashed state.

19. The handwash monitoring system as set forth in claim 17, wherein said plurality of beacons communicate with said badge using wireless means

20. The handwash monitoring system as set forth in claim 7, further comprising a plurality of sentinels equipped with one or more of audible means, visual means and remote means for issuing a warning when said badge is within a predetermined proximity to any one of the plurality of sentinels while registering the hands-unwashed state.

21. The handwash monitoring system as set forth in claim 7, further comprising means for preventing reactivation of the predetermined handwash procedure for a predetermined period of time upon the base unit detecting the person has correctly performed the predetermined handwash procedure.

22. A handwash monitoring method comprising the steps of:

instructing a person to perform a predetermined handwash procedure using a base unit;

deactivating a faucet for a predetermined period of time upon the base unit detecting the person has correctly performed a specific step of the predetermined handwash procedure;

detecting whether the person has properly performed the predetermined handwash procedure using the base unit; and
